ELECTRIC HAULAGE IN MINES By LEONARD WILSON·

The 'general problem of haulage in mines, like all other engineering problems, reduces to one of dollars and cents, and therefore, a clear birdseye view of the economic side of the problem is of prime importance. Tn making a study of the costs of elec­ trict haulage it is better to consider a case where the advantage of electric over other forms of haulage is the least apparent; and for that purpose a study is made of a typi­ cal lead silver mine. The mine has one central shaft sunk

safety devices. Proportion of underground cable for 8,000 feet horizontal run and 2,200 feet vertical. Propor­ tion of surface transmission lines and transformers. This comprises the total equipment, installed and housed, for furnishing direct current to the trolley wire .. $13,000.00 B-Trolley (4-0) wire, suspen­ sions, and rail bonds for 34,200 feet of track installed

to a depth of 2,200 feet with main trans­ portation tunnels at various levels_ The economics of electric haulage is consid­ ered only for these main transportation tunnels. The accompanying diagram gives full particulars of the location and lengths of these tunnels together with the total tonnage and ton miles handled at each level. It also shows location of generator sets. The cost items for the electrical equip­ ment are as follows: A-Four motor genarators sets with control e::tuipment and

Total annual cost ......... $21,420.00 Each of the four-ton locomotives llas a

capacity for hauling a maximum train of twenty-five mine cars holdin'g 37:y" tons of ore. The average length 0.1' track per loco­ motive is .93 miles and at the average oper­ ating speed the time taken per roundL-ip (allowance being made for switching) is 30 minutes. The maximum haulage of each locomotive per shift is therefore 560 ton miles. With locomotives of such capacity it would be possible to 'lccomplish the neces­ sary haulage with one locomotive on each level working 8 hours a day on the l,()OO level and 4 hours a day on each of the

r

other levels. In actual practice the 1,00Q level would require ,two locomotives artd all locomotives would· work 8 hours (; day. On thIs basis the average haulage p~ loco­ motive would be 209 ton miles per day, or 37:ih per cent of their maximum capacity. The cost of haulag'e under such conch­ tions with locomotives working at 37:ih per cent maximum capacIty is $21,43'iJ.OO per annum for 627,0(}1) ton miles, which is equivalent to' 4.07 per ton mile, apportioned as follows: Interest on capital ........ ,435c 10.6%)

Depreciation of equipment ..940c ( 23.1 %). Repair and maintenance ....700c ( 17.30/0) Wages of operators .... ~ .. 1.710c ( 4~.O%) Power for operation ....... ,285c ( 7.0%)

Total cost per ton mile 4.07 c (100 %) It will be seen that the most important item is that of motormen's wages and tMs item is one which depends very much on the conditions under which the mIne is operating. One motorman, with a locomo­ tive of the above capacity, can handle 500 ton miles of material' in one shift, if it is consistent with operating conditions to furnish material at this rate. For a long haul, say three miles, there is no difficulty in furnishing material (ore or waste) for 500 ton miles, but on short hauls the loco­ motive cannot be loaded up to full useful capacity and a limit is reached at which mule haulage or hand tramming is more economical. In laying out a system of underground haulage it is of the utmost Importance to reduce the labor item of operation to a min· imum and at the same time to eliminate the possibilities of interruption to service. Motor generator sets must be equipped with fool-proof automatic switch equipments; the most up·to·date construction must be used on tracks, bonds and oveThead trolley; and locomotives must be selected that will have the least possible maintenance. The ques· tion of possible danger to human life must receive 11rst consideration and is one of the limiting factors in the selection of a suit­ able system for electric haulage. In order to insure safety to life it is ad­ visable to limit the' trolley voltage to 250 volts. A number of mines are operating with 500 volt trolleys, but this cannot be considered safe practice in the small tun­ nels of the average metaliferous mine as there are numerous cases on record of men being killed by making contact across 500· volt circuits. By reason of this low voltage it is 'imperative to feed the trolley at a !'number of points in order to avoid exces­ sive drop of voltage, and this has to be done by the installation of a motor generator set at each of these points. For average condi­ tions the distance between motor generator sets should not exceed 10,000 feet. For this particular mine four motor generator sets are required, located at the points shown on the diagram. These sets are furnished with alternating current from

the four units. In the older forms of equip­ ment the generators would be provided with adjustable ,fieldrheosta:ts and hand operated switches and the process of starting a mo­ tor generator set required some little skill, After the motor had been started it would be necessary to adjust the generator volt­ age to approximately the voltage on the trolley from the other sets, then close the main switch and readjust the field rheo­ stat to secure proper division of load.

Where the cables have to be suspended in vertical shafts the band armor is replaced by wire armor of sufl'lc\!illt strength to carry the entire weight of the cable and covering. The cable, in such cases, is securely clamped at the top of the shaft by a long cast iron clamping sleeve, deslgneu to support the weight, of about 1,01}0 reet of cable, If the shaft is deeper >,

If the polarity of the generator became reversed it would be necessary to throw the field on to the trolley and then throw it back on to the generator terminal before switching in the generator. With the improved system each generator is equipped with a Tirrill regulator which maintains the voltage at 250 volts under all

THE WISHART GOLD SAVER

One of the most interesting and success­ ful placer mining machines now on the mar­ ket is being manufactured in Los Angeles. This is known as the Wishart New Age Gold Saver and Amalgamator, and its adap­ tability to all kinds of gold placer mining has been most satisf!lctorily demonstrated in California, Arizona, and in the gold dis­ tricts of Alaska. The fame of this machine has been known in Salt Lake for soone time, and a number of our leading mining men have been interested to the extent that they have visited the city of angels for the express purpose of looking it over. Considerable interest will be felt locally, therefore, when

Mr. Wishart Luilds a dry placer machine as weB as one using water in its operation. The gold saver purchased by the Hastings company will require water in the recovery of its placer gold. The gravel is deUvered into a hopper placed above a belt conveyor by means of scraper or steam shovel. From the hopper it is fed antomatically through a gate upon a belt' conveyor, which delivers it into the ,boot of the elevator, where it is picked up

material is kept equally as loose as in panning. To elean up, the operation requires a period of about twenty minutes. This is done generally !Il the morning, at noon, and at night. But it can be made more fre· quently, if desired. Every machine turned out by Mr. Wish· art is built to meet with c~nditions and requirements I}xisting in different placer diggings. In this instance, with the rna· chine constructed for the Hastings com­ pany, he has given his guarantee that the machine will save ninety·five per cent of the gold content of the gravel, or material, that is free. An eight·horsepower gasoline engine will ,be used with this machine. The cost of power will depend upon the depth of the gravel deposit and the length of elevator required.

In the spout the 'material comes into contact with the water, which washes the gravel thoroughly, before it passes out through the perforations in the end of the revolving screen into the sluice boxes. The sluice boxes are lined with sheet iron riffles so constructed that the packing of the material, as it passes through the boxes, is impossible. Therefore the gold, or any other heavy substance or material, is precipitated at once to the bottom of the sluice box and held in the riffles. The reason why the material cannot pack is because the sluice boxes have a vibra· tion of 165 strokes per minute, so that the

(Special Correspondence.) Lovelock, Nev., March 4.-There is con­ siderable activity in the Velvet district. about twenty·two miles west of Lovelock. It is not a new camp, as it was discovered in 1907, but considerable rich gold ore has been opened up recently at a depth of 150 feet. The formation consists mainly of altered dacites, rhyolites and trachytes and eruptives of this class, highly silicified and oxidized and resembles the Goldfield coun· try very much Good ore has been shown on the two principal properties, quite a body of $200-ore having been found on the Davis property.

GEOLOGY OF DOLLY VARDEN DISTRICT By). ). BANIGAN

The Antelope mountains are about thirty miles in len-gth and lie in the south­ eastern part of Elko county, Nevada. The southern half of the range is composed ot a chain of volcanic hills extending into White Pine county, The northern half consists of an erup­ tire granite core tilting carboniferous lime­ stones and shales, followed by intrusions into the granite and sedimentary beds of bodies and dikes of monzonite 1quartz porphyry) and andesite porphyries.• Later, extensive rhyolite flows came up, covering a portion of the granite, earlier basic porphyries and sedimentary beds. The rhyolites are more extensively de­ veloped on the eastern side of the range, Where the contact is plainly shown, cov· €Iring earlier andesite hills and extending in great flows into Antelope valley. There are three classes of ore deposits: (a) Fissure veins in porphyry, granite and sedimentary beds, (b) Contact deposits be­ tween granite and porphyry and lime and porphyry, (c) Disseminated ore in porphyry. Ores of the District. The ores of the Mizpah-Dolly Varden districts are connected with a great porphyry stock. from one quarter to one mile wide and fourteen miles in length. It strikes northwest·southeast 'across the range, intrudes the granite on the north and limestone and shales on the south, sending nU'merous dikes into the granite and sedimentary beds. Following the intrusion of this great porphYrY body the overlying limestones and shales were extensively metamorphos­ ed, fissured and faulted, and great quanti· ties of iron brought to the surface, which were later leached and the copper deposit­ ed in the underlying porphyry. The gossan and sedimentary beds have been removed by erosion from the northern portion of the belt, exposing great areas of mineral­ ized porphyry. That the iron cap was copper 'bearing is evidenced by the pres­ ence of disseminated copper sulphide and carbonate in the porphyry on the surface away from any fissuring. The. ore ·bearing porphyry was technic­ ally classified as a feldspar porphyry by Emmons and Hague in U . .s. Fortieth Par­ ·allel Survey and is the same as the ore bearing porphyry of the Ely district, sev­ enty-two miles south. The section, under the name of Wachoe Mountains, was ex· amilied by government geologists and are· "port with geological atlas published in 1877. The porphyry and ore deposits are per­

t

pi

haps of the same geological age as those of the Ely district. The surface and geological conditione are the same, except that there has been more fissuring in the Mizpah district and the iron cap with overlying sedimentaries has been stripped off by erosion. Large masses of porphYrY appeared to have been pyritized and the leaching of the iron gives it a brownish or reddish appear­ ance. It is not improbable that a portion of the copper in the zone of secondary enrichment was derived by a leaching of the metals in the porphyry as well as t,om the overlying Iron cap. Disseminated ore has been demonstrat­ ed on the south end of the porphyry stock at a depth of 135 feet by Captain J. A Hassell, and associates, of New York, with churn drills. Drilling continues with a report that a working shaft is now plan­ ned for development. Several Promising Properties. There are several promising properties under development, showing copper in the sedimentary beds in the immediate vi­ cinity of the porphyry stock, with silVer and lead deposits on the south end. The Victoria mine is situated in lime­ stone. The last thirty feet of the Victoria shaft is In native copper ore averaging 6.8 per cent. Drifts have been extended from the bottom of this shaft twenty feet to the east, forty feet to the west, and fifty feet to the south and the limits of the ore body have not yet been determined. The Nevada -Butte property, recently incorporated by Salt Lake people, lies in the extreme north end of. the porphyry stock and comprises fifteen claims, original locations of the Mizpah district. The property shows three different sets of fis­ sure veins; contact deposits 'between gran­ He and porphyry and disseminated ore in a porphyry are a 1,200 by 1,800 feet. Four large north-south fissure zones forty to 300 feet wide extend through the Nevada-Butte, cutting both granite and porphyry. Three or four large and num­ erous smaller, parallel fissures connecte(! by innumerable cross veins and feeders occur in each zone. The country rock, between parallel .fissures, is highly altered and mineralized and shows sulphide and carbonate of copper on the surface. It is highly probable the veins will laterally enrich the porphyry for a considerable dis­ tance from the main fissures. The group shows sixty different ore croppings, carrying values from one to fifty-three per cent; $2 to $380 in gold and one to forty ounces of silver. There is 750 feet of development in seven shafts q

and tunnels. Three shafts show direct smelting ores in fissure deposits, from one to four feet wide, assaying six to twenty per cent copper and $2 to $14 in gold and silver. T'hree hundred feet of sinking on the fissure deposits, and 150 feet or less in the j}orphyry, shOUld reach the zone of second­ ary enrichment. The property is 'situated within five miles east of Mizpah siding on the Nevada Northern railroad and plenty of water Can be had in Steptoe valley for smelting and concentrating works. Surface showings have been pronounced more favorable than on the south end of the belt where disseminated ore has bee» proven, and the Nevada-Butte is now prac­ tically certain of opening up a similar de­ posit. The right geological condition exists in the Mizpah-Dolly Varden 'belt for making big copper mines and all that is required to bring out another great copper camp in Nevada is development. ROSE SPRINGS MINING CO.

The Rose Springs Mining company, of San Francisco, is actively engaged in the development of its property at Tuolumne, California, and expects to get into oxidized ore, again, in its tunnel, in the very near future. A fault cut eft the ore body soon after the company's neW mill had been started, and since then the plant has been closed down. In searching ·for the lost ore a 7-foot vein of $20 sulphide ore was opened up, for the treatment of which a concentratin~ ,plant will be constructed at a later date. The oxidized ore, for the handling of which the mill was constructed, was four feet in width between walls, the mine run averag­ ing, without sorting, ~15 to the ton in free milling gold. The mill is operated by power generated by gasoline engine, but a water-power plant will be installed as soon as practicable, as Well as an 1,800-foot aerial tra'mway. The company was fairly launched on a profit-making basis at the time the fault was encountered, and it has taken time and money to rel~ate the body of oxidized ore. Now, however, conditions are more satis­ factory, and it is hoped, within a reason­ able tife, to be ahle to report that the Rose .springs is on a self·sustaining and paying basis. The company also owns a group of valu­ able claims near Butte Mountain, Nevada, In the development of which, according to advices from San Francisco, work will be resumed as soon as possible.

The Country Boy mine at Breckenridge, Colorado, has been started up under the management of Warren Page. of Leadville.

I feel safe in stating that more than double this vol­ umeo! water will be developed ·before the tunnel is completed, hence it is evident that in its Snake Creek interests, in this water and power alone, the Daly-Judge company has an cextremely valuable asset.

REPORT OF THE DALY -JUDGE

The report of the Daly-Judge Mining company, operating at Park City, has been issued for the year 1912. General manager Lambourne says; In presenting this, my annual report, as manager of this corporation, I ,wish to con­ gratulate you on the improved showing over that· of Hill, in increased production, and earnings and the decrease in development expenses, in spite of the fact that the new work accomplished ranks with the most extensive in the history of the company. Total development work amounted to 9,784 feet, of which 4,002 feet were driven during the last three months of the year. Since September 1, 1912, systematic ex· ploration has been largely increased under the contract system, by Which approximate· ly double the footage is driven in a given time, with no greater cost per foot than has been the case heretofore. The unexplored portion of the mine is unquestionably promising, and with the knowledge gained during each year in its development a continuation of the contract system of development will open up the resources of the property with the least de­ lays. Production last year totaled 62,606 tons of ore, the net value of which was $728,­ 381.36, as against 59,461 tons valued at $577,040.74 in 1911. The company closes the year with a surplus of $524,.570.05 on hand, after the payment of $225,000.00 in dividends. As forecasted in the last annual report, the company has enjoyed a much better in­ come from its zinc middlings than hereto­ fore, receiving for the same in 1912 an av­ erage of $27.29 per ton, against $10.83 dur­ ing the preceding year. This was due to the increased market value of spelter, to improved methods of concentration and to the favorable terms of the contract under which this product is marketed. In directing your attention to the en­ closed report of the general superintendent, I desire to urge reference to the map which is made a part of this report, showing a vertical projection of the mine along the Daly fissure with Its various workings duly named whereby the operations of the com­ pany can better be understood. This map shows the White Pine work­ ings upon the Daly-Judge property, also, from whi::h, many years ago, considerable ore was' taken. An interesting account o~ the early productivity of this White Pine section has been made a part of the United States Geological Survey publication on the Park City district which was issued by the government last year. From the 500 level on down the Daly-Judge company is driving to the southwest to get under these

early workings to demonstrate the contin­ uation of the ore bodi.es with depth. The 500 level will 'give 400 feet of vertical depth from the bottom of the White Pine shaft. This work is important, and a large extent of virgin country will be explored. Since the close of the year development work on the 1,900 and 2,300 levels has been vigorously going on, At the present time the face' of the Snake Creek drain tunnel is 5,700 feet from the portal, and the water flow is 6,300 gal­ lons per minute. There is now available in ORE,

prospecting and exploratory work during the year 9,784 feet Total production 58,­ 951 tons milling ore and 6.138 tons ship· ping ore. During the year one Wilfley table, one Multideck Wilfley slimer, two ·Callow tanks, one Richards-Janney classifier and one new jig have been added to the equipment of the mill, which resulted in a closer saving and a better separation of lead from zine. Two new tanks and one old one have been installed at the head of the mill, giving a storage capacity of 115,()00 vallons of water. The mill has been kept in good repair. The mill treated 58.951 tons of ore, dry weight, from which 13,419 tons of lead: con· centrates and 4,300 tons of zinc middlings were made. There were concentrated 4.4 tons of crude ore into one ton of lead con­ centrates, and alJ products combined, 3.4 tons into one. Reserve ore bodies exist on the 600, 9'00 and 1,100-foot levels. There are some re­ serves in No. 1,218 stope and the ore may extend indefinitely to the northeast. With the rapid rate at which development is now being prosecuted more new ore bodies may be expected to be opened during 1913. Accompanying the report is the map re­ ferred to ,by Mr. Lambourne, which is a good example of the kind of information which we have advocated from time to time in our editorial columns. --"--()-~"--

The South Nevada Gold Mining com· pany, whose property is located eight miles southeast of Las Vegas. Nevada, has ar­ ranged with a machinery house {or the equipment for a 100-ton 'milling plant, con­ Sisting vf stamps, rolls, and a cyanide annex, which is to ,be ready to go into commis­ sion about the first of May next. The pro­ cess of ,recovery will be amalgamation, fol­ lowed by leaching In cyanide solution, and it is claimed that a very close saving of the gold CO!ltent of the ore will be made.

The company quite recently acquired all of the land between its mining property and that of the Winterwood Land company. Plenty of water for milling and camp pur. poses has been fecured ,by wells, the water rising nearly to the surface. The company is a very close corporation, and none of its Hoek is for sale. A power house has been located near the mouth of the main working tunnel, and comfortable .quarters have bEen built for the manage­ 'ment and employees. Dr. G. W.

MORE ON THE EAGLE STRIKE.

In our last issue we published details of the new strike at Eagle, Colorado, and now add the follow ins from the columns of the Denver Republican. The ore is found in laminated sandstone, Commissioner Henahan says, and the rich values are scarcely visible to the eye--ex­ cept in the ribbonlike structure of the high grade that shows the coloring and structure of silver sulphide. Other specimens from the general ore show silver ,brcYmides, while other parts indicate the presence of uran­ ium, vanadium and carnotite. The sand­ stone Is dark, and may be of the Dakota or La Plata group. At this particular strike the foot shows a fine-grained, yeJloWish por­ phyry, and it is believed that the "hanging waH," when reached, will be La Plata sand­ stone. The combinations are almost Identical with the great vanadium mines of southern Colorado, with the exception that in Salt creek valJey development gives greater and more pronounced values in silver contents. The llace Qf discovery is ideally situated. A good road leads to the section where the openings have been made, there is plenty of water for milling and camp purposes. and timber for all mining uses can be had within two miles of the strike. The dis­ tance from the town of Eagle on the Rio Grande railroad is less than ten miles, and a stage line cuts the country down to the old camp. The sandstone are·'l is extensive. There seems to 'be a parallel line of three hill sections running from southeast to north­ west. Creede is the western line, Salt creek country the central and Red Cliff makes the eastern line of contact. The formation is in no wise similar to ~hc s"l.noston~ sE'ction eIther Tlest or east. Old ti;."ers call the ,'andstolJe "quartzite," or "soft quartzjte." It is really a sandstonf'. rrobably Daltota. "Th<:J strike over ~here in Eagle IS on

the level, all right," said Commissioner Henahan. "Osc;tr Kempf. an old· timer from Boulder county. E. E. Glenn and R. S. "Wolverton opened up this ore some time ago. They k€pt their discovery quiet. After they had secured all th€' ground they wanted, they made their strike known and came to Denver with samples of their ore and had the runs made here with Henry E. Wood & Co. The unusual returns caused them to come to me with the information. "The entire development that has 'been done on the prospect shows nothing but ore. The crosscut is still in ore, and the bromide of silver is scattered all through the rock, as are the uranium values. The ore shown in the samples that I have here shows the laminations with the streaks of the silver sulphides in plain evidence. This country has been known for many years, but always has been turned down on account of the values being in the sandstone formation. Not until the discoveries of vanadium in the southern and southwestern part of the state has any interest been aroused in this sec· tion. "It looks from what can be seen no"W that there will be a regular mining excite· ment over there when the snow goes off. I would advise everybody to remain out of there until at least the middle of July. There is a heap of snow down there, and pretty soon there will be no less than ten to fif­ teen feet on the level. This will remain on the hills for months to come. There is a small stampede in there now. 1'he men are the hardy prospector type that never con· sider weather, hardships or anything else­ they go and that's all there is to it. The locations from noW on will "of necessity have to be made on the snow-and they will legally hold just the sa'me as any other loca· tion any time, ill other words, the work ot dis-covery will have t:l be made in regular form, as ,provided by law. "Below the opening made by the dis­ {!overies, I found blue and crystalized lime. But the dark sandstone is about the same as down below. This strike means the re­ juvenation of mining here-and there are other eamps to be heard from In a short time that will advance the indUstry to the same plane that obtained years ago. The twenty·year cycle is here, and it has come on schedule time, just at the ti'me when the mining industry was quiet. Yes, I think that thi.s new ~ection will make gOOd." Henry E. Wood, of Henry E. "Vood Com­ pany here, said: "1 have known of this district for the past ten years. 1 have always known it to be in the sandstone, and to be rich in silver. Determinations that 1 have made there from time to time convince me that there is an immense area over there that will undoubtedly make one of the great sil­ ver camps of Colorado."

MIAMI IN 1912. Mine Being Prepared $0 That Best Mining Methods May be Later Adopted.

J. Parke Channing of the Miami Copper company, operating at Miami Arizona, has given out the following statement. as to oper­ ations in 1912: In 1912 the development of the Miami ore ·body for mining was extensively carried forward by extending the extraction drifts on the 420-foot level so as to undercut the main orebody of that level, and also to get underneath the Captain ore body and to connect wHh the Captain shaft. The devel­ opmentof the 570-foot level was extensive so as to prepare this level for an extraction level. It is being cut up in the same rec­ tangular gridiron fashion 'as the 420-foot level, and is so arranged ,that when the final method of mining is determjned upon, it will ,be aYaila'ble for sny method selected. The third extraction lcyel was arranged for in the main shaft at a depth of 720 feet, but nothing has been done ·at this point, as it may ·be advantage,ous to put this level to a still greater dep1h, depending upon the ore development. O:f the ore mined in 1912, a large pro­ portion came from development work and from the square sets and slicing. The sl·,rinkage stopes whi{)h have been tried out on the 420-foot level are nearly all in shape, but the wo-rk of cutting out with square sets above them and the intervening pillars was not completed. The indications so far are that this meth{)d of combined shrinkage stopes and pillar slicing will prove to be economical both as regards per-centage of extraction and cost. The early estimates of ore reserve as­ sumed the or'e to extend to a depth of only fifty feet below the 570-foot level. During the latter part of 1912, eight diamond drill holes were put doWn from the 570-foot level. showing that the ore extends in pla-ces from 100 to 200 feet below that level,and in some places the ·bottom was not reached. The indications are that the ore will gO to a muoh greater depth than was expected, 'following along the line of the Gila conglo­ merate fau!t. The results of 1912 show a material increase in the ore in sight, to­ gether with excellent prospects for continu­ ation in depth. In January, 1912. the mill w'as treating at the rate of 2,200 tons per day, and since June 1 at the rate of nearly 3,000 tons per day. The approximate produdion for the year was 32,000,000 pounds of refined co·pper. The year's work in the mil! demonstrated the increased efficiency of the Hardinge peb· ble mills over the Chile 'mills, and orders have been placed for the Hardinge pebble mill to replace the Chile mills as they are worn out.

is being introduoed. one at a time, in each section of the mill. In addition to this, expel'iments indicated the desirability of saving ·a certain amount of mineral which is at present I{)st in the sand tailing, and these imvrovements will gradually be in­ stalled during 1913. The indications are that, with these betterements the capacity of the present mil! can be materially in­ creased over its present limit of 3,000 tons per day. In the power house the spaces left for new machinery were filled by the installa­ tion of a 600·horse vower boiler, a 4,000 cubic foot air compressor,a 1,250 k. w. gen­ erating set, and a sec{)nd condenser. A second 400-horsepower synchronous motor was installed at the Burch pump station, tbus giving the pumping plant with its two pumps a capacity of 2,400 gallons of water per minute. A tailing elevator was installed below the mill, raising the tailing to a height of seventy-five feet, and permitting of its discharge in the se-cond gulch 'below the mill. On the surface, a number of houses were built, and a hospital, jointly owned by the Miami and the Inspiration, is now being erected. The work for the year pro­ gressed smoothly and ,the !proSipects, as above stated, for increased ore reserves and an increased tonnage in the mill are most exceIJent. ---~o,---

PACIFIC GOLD MINING &

MILLING.

H. C Johnson, secretary of the Pacific Gold Mining & Milling company, of Ameri­ can Fork, has issued a report of operations for the company for the year 1912, from which the following is taken: During the year the mine has been continuously operated excepting for a short time with a force of from three to nine engaged. A total of 220 linear feet of drifting and 3,950 cubic fet of stoping was driven by hand power. During the year five railroad cars of crude ore and jig concentrates were ship­ ped to the International. This ore amount­ ed to 416,982 dry pounds and brought $8,­ 139.49 smelter'net, as ::Igainst ·$6,204.05 for the year 1911 and contained 3,614.56 fine oz. silver and 214,019.45 pounds of lead. Gold. copper and zinc values were normal. Ore lots 10 and 12 containing 105.3 tons brought $5,061.00 or $48.06 per ton, but the average price was $39:04. .In June a lease of the dump mill ore was granted to Hugh Jamison, who in· stalled a hand jig and shipped lot 11, sold for $1.195.38. The north drift, north work­ ings was extended and now shows indica· tion of the bromide ore which composed lot 1 taken from the surface. In t.he summer the main vein was found gOing south from main west drift, north workings, by Geo. Tyler, foreman. J:t haa been previously lost on account of a fault IltNt ,&or \iTs.iIllmediatel y started

stoping and drifting south on the vein. 1<'01" 120 feet the drift showed continuous ore from twelve inChes to five feet wide though it was crushed from the fault 'movement and of lower grade than the south workings ore and more oxidized and higher spar contents. Sixty feet more drifting will connect north and south workings. This work is let to Martin Strehle, contractor, of Salt Lake, and should be finiShed February 10, 1913. Three small stopes were made during the year from lower tunnel main vein, but the ore in each is pinched at the top. The ore is generally in lens·shaped bodies, be­ ing widest at the center and tapering at the ends. The Kruse stope showed a width of four feet solid galena at one time. The ore was broken as fine as possible and separated on the grizzly, the coarse being hand·sorted on the table and the finer run through the jig and sluice boxes. The coarse mill ore was saved on a sep­ arate dump. For the first year in its history the company has made a profit. although a small one. The vein is now opened for 600 feet and neither end reached. The average width between massive quart· zite walls is from six to eight feet. The ore and gangue are very hard, making working and mil costs extremely high by using hand labor. Leasing might be profitably adopted on the fissure 'ore but the opening of bedded or carbonate bodies by the company is of prime importance. is strongly recommend­ er! by E. P. Jennings, its engineer, and can now be undertaken with more confidence, with the knowledge gaineJ by development of the fissures at depth.

MIN I N G STIL.L ANOTHER NEW COLORADO CAMP State JCommissioner of Mines Favorably Impressed With Gilmore Camp.

"People all over the country are writing me insistent requests, and the Denver and outside state mining 'men almost demand, that I make :i trip into the new camp of Gilmore, ConeJos county," says State Com­ missioner of Mines Henahen, to the Denver Republiean. "I had a long interview with a mining Ulan Who come out from there \Vednesday. He is abSolutely reliable and is n~t inter· ested in that country to any great extent. "He showed me plain and roast~:l speci. mens of the ortl that was taken from the Gilmore strike. .. 'This new district.' he said. 'covers an area tell 'miles long and eight miles wide. The contacts along the brecciated trachyte intrusions. where the new discoveries have been made, show ore in almost every case at the rurface. As a matter of fact, in the area of mineralization, as shown by Hayden, mines are being developed. "'Almost forty years ago this section of the country eame into mining notice. There are many dumps throughout the section men­ tioned. In every and all cases the suI· phides with tellurium are present. The dumps all assay, I mEJan in a commercial way. Without the pregent flux that is used in determinations of the tellurium ores, the values show very poorly. and would not in· terest either a prospector or investor. "'This is undoubtedly the very reason that this immense area of mineralized zone has laid idle for so many years. The new impetus was really given to prospectors less than six months ago. " 'George Gilmore, an old-time Ouray and Silverton prospector and miner, went into this country last summer. Gilmore sampled all of the old dumps. At last he received the returns that he was looking for, that is, rich prospects. He samp:ed old work­ ings along the Alamosa river, on the south­ ern slope of Lookout mountain. He saw figures en returns that showed better than $2,000 per ton. Hurrying back to the old workings, which were caved in, he started to work. The original prospector had taken the wrong streak, missing the nch quartz by less than a foot. Gilmore took more sam· pIes and had them assayed, notwithstand­ ing that free gold showed in a sparkltng, glittering maSs all OVE'r them. The discov· ery was verified, the second lot of assays being higher still. He sent the pulp to Cripple Creek and received even better re­ turns. "'The .hill where he made his find is very steep.

"'He has had five miners at work driv­ ing the tunnel since last November. He has sacked every pound of the ore that he has mined, and dUring the past month every round that has been blasted has been taken down on a sheet. H 'When the richness of the Gilmore strike became known, men from Cripple Creek began to send m their field men and engineers. The discovery was authenticated. J. T. Milliken of the Cycle, A. E. Carlton, and other well known mining men, sent their men back into the new camp and in No­ vember lllld December made locations. They completed their work of discovery along in early January, and the miners were com­ pelled to come out through the heavy snow. " 'Of course, the insiders went into Gil­ 'more and staked the whole country for miles around. There will not be a chance for t':!e location of any grouD(1 within at leaEt a six mile radius of Gilmore.

He made his find of rich ore near the mouth of Whitman fork. This is between Jasper and Stunner, in Conejos county.' "This is the second man that has come from the Gilmore section in the past week. Their manner shows convincingly that the rumors that have run and been made public annoy them. FamiI!ar with the game, the fact crops out that the stampede that will go in will, in all probability, take from them open ground that they had their eyes upon, for location. "This has deeided me to make the trip into the new camp. I am literally forced to go," £aid Mr. Henahen. "I Will, of neces­ sity, have to make at least twenty miles on webs, pack grub and ·blankets. The San Juan mountains are not new to 'lIle. I was in them for the better part of my life. "With the present heavy snOWfall, and the snow that may follow, it makes sure that bare ground wi!! not 'be seen down there until the month of July, at least. "No, I hardly think that there will be

REPORT OF THE RICO·WELLIN.GTON.

W. Lester Mangum, of Provo, Utah. sec­ retary of the RiCO-Wellington Mining com­ pany, a Knight company operating at Rico, Colorado, has prepared the following report, signed by the general manager: "A two-bucket tram, extending 2,500 feet from the WelIington tunnel to Winkfield switch on the Rio Grande Southern railway, has been installed and is in operation. Th~s tra'm has a capaeity to handle from fifty to sixty tons of ore in eight hours, costing twenty-three cents per ton placed on cars, as compared with the former cost of ninety cents per ton. wagon haul. This equipment includes a two-compartment ore bin and terminal at the switch as well as at the tunnel, and an auxiliary terminal and load­ ing station connected by trestle with the bottom Of the large storage platform twenty­ five feet lower than the tunnel level. This platform has a storage capacity of from 4,000 to 5,000 tons and is at present used for the storage of zinc {)re. Smaller storage bins and platforms are also provided for the storage of

The strike as a weapon of miners is again made ridiculous by the action of em­ ployees of the South Hecla Mining company, in Cottonwood canyon, who walked out be­ cause the courtesy of that company's ample boarding house was extended to a handful of non-union miners made homeless by the destruction by fire of the boarding house of a neighboring company, whose men reo fused to join in a former strike.

It has become the fashion for state leg' islatures to consider the passage of "blue sky" laws for the protection of investors. The state of Utah has just escaped legisla· tion which would have the same result on the mining industry in Utah as that other Kansas blight, the drought, has aforetimes had on Kansas crops. But other states arEi considering similar laws, so that a brief mention of the grave defects in the law that was proposed for Utah may not be amiss. In reading the draft of the original pro· ,posal, all goes serenely through definitions of investment companies, stock brokers and agents, till the first demoraliZing proviSion is reached. namely, the necessity for obtaIn­ ing a license from the state bank commis­ sioner before engaging in stock selling. Just why the state bank commissioner should have anything to do with the mining indus­ try is not evident. It is notorious that east· ern people, who may be expected to have similar feelings to a bank c01llmissioner, in other words, so called investment advisers, are, almost without exception, united in con· demnation of mining investments. A hoS­ tile aVmosphere is thus Introduced at the start. A certain amount of information must Pie furnished before a license will issue, which might be a satisfactory requirement, if the licensing authority were the proper one. A further illuminating provision is made that ~the granting of a permit to said stock broker shall 'be further contingent upon said stock broker having the reputation of handling such stocks, bonds and other securi­ ties as said bank -commissioner shall decide to be good legitimate investments." We always felt that that there was room for grave doubt, even among experts in mining deals, engineers and -brokers, as to Just what was a good legilimate investment. The same investment may be legitimate for one man and exceeding unwise not to say illegitimate, for another. An'd, to permit one who may not have the wisdom to say 7 ; f17

that such a mining stock is legitimate and that such other is not, to decide this 'mat­ ter, is farcical. 'vVe have already spoken of the tendency in certain banking drcles to regard all mining investments as undesirable.

The Chino Copper company, of New Mexico, has issued its report for 1912. Pro­ duction for the year was 29,237,966 pounds, from milling 1,120,375 tons Of ore. Profits were $2,352,822. The cost of copper for the last quarter was 8.49 cents a pound, an in­ crease due to treating a lower tonnage, and producing lower grade concentrates. Aver­ age daily tonnage treated was 4,920 tons during the last quarter, against 1,763 for the first quarter. ,

COMMUNICATION,

The Editor: We wish to thank you for space allotted to the Farmington Oil situation in your issue of February 28th, Some few inaccuracies crept into the reo port referred to and possibly it may be of interest to give additional data. This Mattox well is situated sixteen miles west of Farmington in a valley some four miles wide, known locally as "the Meadows," as also near the center of an immense fossil bed, which was surveyed and very favorably reported on, by Prof. Lake, the well known government geolog· ist, some years ago, You will find this field marked as indicating oil on official geological maps, At a depth of 1,717 feet quite a deposit of oil was encountered which upon analysis proved to be high in gasoline and paraffine, Work on the original well Is resumed after necessary repairs were made and this company proposes sinking to a depth of 3,000 feet if necessary to make complete and convincing demonstration as to quantity, Something near Ion barrels were drawn from the well at time oil was en· countered, A telegram just recei ved from A. R. Ross, a Denver oil man, gives notice that he has deposited $6,000 ·as the first in· stallment of $8,000 to put in a new drill· ing outfit with a capacity of 4,000 feet, He was here five days ago and appeared en· thusiastic over the oil signs and forma· tions, It is definitely known that a strong com· pany is ·forming in Durango to put down a well, Their expert has been here nearly two weeks, A Gallup, New Mexico, com· pany is forming to invade this field, as also another from Colorado Springs so far positively known of. .contrary to your former report already mentioned, no other oil well is being sunk within one hundred miles of Farmington, Oil operators from .california, Wyoming and Texas have recentlv visited and in· spected the field and all seem highly pleased.

The Prospector and His Burro

ing another double-c'olllpartlllRllL shafl..

(By Will C. Higgins,)

"I see," said the prospector to his burro, "that yon have been up on the hill looking down that old double·compartment shaft, and that yon have arrived at the conclusion that it would take a thousand burros to fill it up, providing they shonld come along and happen to fall into it; and you shudder at the thought of the possibility of that friend of yours, that lop-eared outlaw of a jack, leaving the trail and meeting his finish in its cavernoUs depth, It is true that there is danger there, both for man and beast, and the collar of the shan should be se· curely covered, as it w!ll never be used again, and is a menace at any and all times. "This shaft," continued the prospector, "was sunk by a company that was flnsh with money but woefully lacking in mining experience. The manager was employed be· cause he was a friend of the presil!ent and was an expert sausage·maker; and the pres. ident and his board of dir·ectors were un· animous in the opinion that anyone "lho could make good sausage would fill the ,bill when it came to such an easy job as sink­ ing a hole in the ground and finding ore· bodies, and so he was employed, The manager was enthusiastic over the proposi· tion, and labored under the impression that the entire group, owned by his company, was one vast treasnre house, and that orEl existed in great deposits, in chimneys, pipes, and in the bedding planes, under every 1nch of its domain; and so he decided to go after this great weaith in a proper manner; ifor he was going to show the mining world a few new wrinkles in mine development and operation, "And so the double·compartment shaft was started, although there was no indica, tions of the presence of ore to be seen any­ where in its vicinity. At a depth of 800 feet the manager began running drifts in different directions, and about 2.000 feet of work was done in this line before he tum· bled. to the fact that the ground was not mineral·bearing, and also became aware that the treasury of the company had ·become aJ.most depleted, Then a halt was called, .WU

Glimpses Into Geological Facts and Prob· lems.

"The frame work of the mountains and how they were reared." By what machinery were mountain· masses upraised? We can only parfially realize that an enormous power has been exerted, (which certainly was as truly a mechanical work as the erection of the pyramids) during recent times, geolgglcally speaking. The past generations. whiph had witnessed the tremendous ·power of some of Qur a.ctive volcanGe:o I:!hought that these forces Were ,adequi!IJt~ of,o,r the prod,uction. both of earthquakes and mountains. It is true that recent histm'y tells us of blown·off mountain caps, of islands li~ted from the bottom of the sea and sustained ever since at an elevation of several hundred feet above sea·level We also know that many mountain-masses consist of piles of stuff brought up by volcanos. Mt. Hood is a pile of lava, Mr. Ranier, also, and every field man has seen some minor·ranges which are entirely made up of lava. But how about the "Rockies," the "Andes." the "Adirondacks," etc. They and hundreds of others show clearly that they are not piles of lava. a:,though some of them may have been covered in places by volcanic materiaL Now here lifting has been done to which voloonie work bears a very feeble comparison. Look at some of these mountain chains. all tne parts (sandstones, limestones, quartzites, schists, granites, etc.,) were formed and adjusted together before the u'plift. We must look for a far greater power than volcanic action. Let us therefore consider another possible force in the following Iines-~ Supposing the theory of a once molten earth is rigtht, let us consider what had to be the natural course of events in the cooling of such a globe. That molten globe must have become encrusted and it is also very obvious that this crust grew gradually thicker and thicker; in this case the transmission of heat from the interior would be retarded. That would imply that gradually a constant temperature would exist at the surfaCe or the earth and also a higher but neverthe· less constant temperature would exist at the mid,zone in the crust. The interior. 01: course, continued, anti continues today, to lose heat, which is transmitted to the outer crust. As this outer crust will not lose more heat than it so receives, It will not contract, nor expand. as it does not under­ go appreciable changes in temperature.

traction of the outer crust. while it. itself, is contracting constant"iy. Now, if the in­ terior is contracting constantly, while, al> we, have seen, the outer crust remains stationary, the crust would become too large for the shrunken nucleus. What would result? The outer crust would cer­ tainlv not remain raised above the nucleus, leaving vacant, or even gag·fiJ:ed, spaces be­ tween the two. If you consider the enormous weight of the atmosphere-four­ teen pounds on every square inch-ana then in addition the enormous weight of the crust itself, then, assuredly, the crust must settle down as fast as the molten nucleus grows smaller. As said before. the outer crust will become too large and set· tling down on the interior nucleus, lateral p~essure, provortional to its own weight, will smash and thicken certain parts of the outer crust. Or, if too solid. the crust will wrinkle-­ just as the skin aT an ap·ple will wrinkie, when the pulp within shrinks through the evaporation of the juice. These first wrinkles. even if covered by the ocean, were the beginning of our chains of mountains as we see them today. As long as our earth Joses heat and con· tracts, Wrinkling tendencies will exist. But after a set of wrinkles has once been developed, later readjustment will find reo lief in the already existing wrinkles,-that means in the enlargement of the first wrinkles. In this way. the first uplifted masses have undergone a second or third upheaval, resulting finally in our mountain ranges as we know them today. Many mountain ranges show clearly that they have been uplifted during different times of the geological ages, which later upliftings. accompanied by extensive fault· ing, haVe brought (and bring even in our time) only disapp'ointment to the mine'r. As most of our earth-quakes OCClIr today in or near mountainous ,regions, the fact remains that this readjustment of the outer c;ust Is still seeking relief at or near the first developed wrinkles. --~.~----

REPORT OF THE NEVADA HILLS.

President Wingfield of the Nevada Hills Mining company. of Fairview. Nevada. has issued the annual report of the company. He says; "We feel that the past nine months' operations have been very satisfactory, in. deed, the net realization for the period be· ing $438,909.66. The report of March 31, 1912, showed that the company was indebt· ed in the sum of $495,.000. whereas, the present report shows the company to be in­ debted in the sum of $100,000, and with available assets that roughly show a sur· plus of $31,000. "In weighing the item of cost per ton, attention is respectfully called to the fact that the property of your company is sit.

uated at a point. which adds materially to the expense both in the matter of supplies and in the obtaining of a good class of labor." Production during the nine months to· taled 29.984 tons of are, the total gross value of which was $804,679.37 or $26.84 per ton, of which $78.104.85 was lost in t;,ilings, leaving the production valued at $726,G64.52. or $24.24 per ton. The total costs of $287,754.86. or $9.60 per ton, left a net operating profit of $438,909.86. or $14 64 per ton, of which $120.000 was wrIt· ten off for depreciation, leaving net profit of $318,909 66, or $10.64 per ton. During the year the company drove 6,855 feet Of development work at a cost of $10.55 per foot. Approximately twenty per cent of this work was d,one on are, producing 3.372 tons of are valued at $71.386.26. or $21.17 per ton. "The power situation, which in the past has caused serious interruption of work. is now very greatly improved, since the com· pletion by the p.ower company of a retain· ing dam which will allow them to impound the rush of water during the early spring 'run·off,' and at this date it seems probable that we shall have continuous power ser· vice in the future. "Being dependent on the mine to fur­ nish water for milling operations. there have been times in the past when produc­ tion might have been increased, had addi· tional water been available. However, this curtailment of production has not been great enough in any manner to warrant the expenditure which would be necessary in order to pipe in water from the outsIde. The plans for development in the immedi· ate future include the sinking of the pres­ ent shaft, which, of course. may materially increase the present supply of water. "During the early part of the present fiscal year the better grades of are were mined and milled for the purpose of cre­ ating a fund to payoff as rapidly as pos­ sible the company's indebtedness and reo dUlCe the interest charges. T,his having. to a large extent, been accomplished during the latter part of the year no particular figure for the mill heads has been pre­ determined, ore of any and all payable grades having 'been mined as encountered. or as circumstances and economy in work­ ing demanded. "For the purpose of this annual report. no attempt has been or will be made to furnish an accurate estimate of the meas­ urable ore.. or 'are in sight,' for such a course would have necessitated a consider· able amount of dead work not justified by conditions. On the contrary. all develop· ment work has been carried on with the idea of rendering such work available for the future ec~nomical extraction of ore, which procedure, previous to actual stop· ping, does not expose ore bodies on enough sides to render them accurately measur·

able. While the result of our exploration work has, in some cases, been disappoint­ ing, it seems within the bounds of con­ servatism to state that there is at the present time, sufficient ore exposed to op­ erate the mill at the present rate of pro­ duction for a period of two years; and it cannot be said that the mine is yet beyond the prospective stage. "Development has been somewhat cur­ tailed during the year past, in order that the indebtedness of the company might be discharged more rapidly and the interest charges wiped out. Now that the company is practically out of debt and has good as­ sets in the way of ore reserves, plant equipment, etc., a more active policy of development has been decided upon. "The work of sinking the shaft will be resumed immediately, and also the coun­ try west of the Big Fault on the 304, Wing­ field and Eagle veins will be thoroughly prospected. Up to this time these veins have been neglected and it is expected that good results will be obtained. Also a large amount of lateral work will be done from the long east drift on the present bottom level, which will crosscut the entire width of the lode porphyries and prospect the eastern extension and continuation in depth of all these veins."

The ore bodies have been completely blocked out and are being put in shape for the most economical mining It is tak­ ing much time to get the raises to the top of the ore bodies and the sub-levels opened, but this work is being pushed rapidly, for the ore cannot be properly mined by the caving system until we are on top of it and have cut the same loose from the cap­ ping, with a mat of timber separating the waste from the ore. Practically all of the ore so far pro­ duced has come from opening and develop­ ment work, and only on the first sublevel, in the Brooks mine, has a very small aIp.ount of slicing next to the hanging been done.

be more apparent during the coming year when in operation over a longer period. However, it is expected that during the coming year the cyanide plant will absorb the extra concentrates without suffering in extraction, and a very material saving will be effected. The reduction in milling costs of 13c over last year is due principally to increas­ ed power and water efficiency. and a small saving in concentration. The mine superintendent reports as fol­ lows: The following shows the year's produc­ tion, COJt of operation and total profits~ Mined and milled, 53,874.08 tons pf a value of $15.341 per ton. Loss in tailings 53,163.15 tons of a value of $1.S33 per ton, with redlization from ore of $13.808 per ton. Per ton costs were as follows: Mining $2.976; development, $1.35; diamond drlJl· ing, .077; milling, 2.960; general expense, 0,431; maintenance, 0.201; marketing bullion and concentrates 0.776; total $8,771, making the direct realization $5.037, to whiCh must be added $0.665 per ton miscellaneous earn­ ings, and substracted indirect costs of .548 and depreciation of $1.175, leaving the net realization $3.973 per ton. The amount of ore produced shows an increase of 1.782 tons, and the average value is 78c per ton higher than that of the preceding year. The costs of mining, development and milling all show a decided decrease. Mining-The results of mining opera­ tions show a decided improvement over those of the previous year. This is due largely to the greater width of the ore bodies and to centralizing the work as much as possible. An increased efficiency, not only in the mine, but also in the mechanical department, is indicated by the folJowing statement of costs: iMining Costs-Details for the year end­ ing August 31, 1912-,-53,874.08 tons mined.

The cost of mining, as compared with $3.360 for the year previous, shows are· duction of 38lhc per ton. This is mainly due to the cost of breaking, which shows a decrease in labor and supplies of 28%c per ton. The cost of hoisting also shows a reduction. Of the '53,874.08 tons of ore hoisted du.­ Ing the year, 4,811 tons were produced from development. Development-During the year the usual amount of development work was accOIU­ pJished, showing a total of 10,076 feet, as against 9,932 feet fOr the preceding year. In addition to this three diamond drill hOi"" were completed, making a total of 1,047% feet drilled, as compared with 1,086 feet for the preceding year. The greater part of the development work was confined to the southeastern por· tion of the property, and has resulted in the discovery of several bodies of good ore. The three diamond drill holes, two of which were started last year, were sunk from the 765-foot level in the northern part (If the property. The most important development made during the year is that of the Shaft vein, which has produced a large tonnage of good ore.

The total cost of development, as com­ pared with $1.55 for the preceding year, shows a reduction of 20c per ton. This is due to the larger tonnage mined, and to the reduced cost per foot of crosscutting, raising and sinking. The cost of $3.95 per foot for diamond drilliqg, as compared with last year, shows an increase of $1.33 per foot. This may be explained by the fact that hole No. 10, which was continued from a depth of 733% feet to a total depth of 1.207 feet, made slower progress as the depth increased, and that hole No. 11, after reaching a total depth of 615 feet, was abandoned on ac­ count of the failure to recover 300 feet of drill fods, which had become fast in the hole. Ore Heserves-In ·order to give an ac­ curate statement of the amount of avail· able Ofe in the mine, it is necessary to out­ line the limits of the ore bodies. On ac· count of their broken and faulted condition, this would not only entail a large amount of unnecessary expense, but also mean the carrying out of a prohibitive amount of development work. with a consequent ovel'­ taxing of the hoisting plant. which Is worked to its full capacity. Therefore no attempt has been made to block out the ore with a view to measuring the tonnage exposed, and, consequently, anything but a mere approximation Of the amount of avail· able ore in the mine is out of the question. This is borne out by the fact that for the last two years the amount of ore estimated has faIJen far short of the tonnage pro­ duced. At the beginning of the fiscal year 1910·1911, the amount of probable ore avail· able was estimated to be 26,000 tons, whereas 53,874 tons have been produced. At the present time, it is estimated that there are 32,000 tons of ore available in the mine. Future development of the ,shaft vein will undoubtedly expose new bodies of ore, and there is every reason to believe that the other veins of the mine will Yield a larger tonnage of ore than can ·be .esti­ mated at this time.

Crosby will enlarge his cyanide plant in the Santa Maria district to treat the accumulated tailings. The Miller & Bauder mine adjoining is preparing to set up a small mill. Both the Copper Queen and the Calumet and Arizona have been doing considerable concreting of shafts, where the ground was solid, and are extending this method of "timbering" wherever possible. The Needles Mining & Smelting com· pany is shipping about 200 tons a day from its Tennessee mine, near Chloride. A breaking dow'n of the loading machinery delayed shipments somewhat recently. . The Bannie \iining company, operating on upper Lynx creek, in the Prescott sec­ tion, will continue shaft sinking soon, the showing made in dOing assessment work having encouraged the owners to develop the property more thorouj;hly. A new shaft on the property of the Horse­ shoe Mining company, at Cerbat, is down -eighty feet and the ore is said to fill the shaft, and it is expected that a good body of milling ore will be reached. Frank ODea is in charge of the work. Walter Myers reports a discovery of gold in a large porphyry dike, near the Frosl place at Wallapai Springs. The ore is re­ ported to be very rich and the energy oj the discoverer is now being devoted to sink ing in hope of proving its continuance. The Gunn-Thompson company has aC quired the Hackberry property, about nlm miles from Kingman. The mine Tlroducec high values between 1874 and 1884, but ha! been idle since that time.

In the Bisbee distrid, it is announced that all that remains for the merger of the Saginaw with the Calumet and Arizona to become operative is the formal sanction of the stockholders of the two companies. A meeting for this purpose was arranged ,for March 10th. Six and one-quarter shares of Sagina 7{ will be exchanged for one C. & A.

The Ohio Mines company, owning the Little Jessie group at Chaparral, will clean out its shaft, which is double compartment to the 300-foot level, and develop the jlrop' erty for the extraction of its low grade ore. A large vein of milling ore was recently discovered on the surfa~e, and, during the time when the property was .ship,ping high·, grade, much eight to twelve dollar ore was uncovered. The Arizona Southwestern Copper com­ pany, operating at CoP'perville, is getting its affairs in shape for operation on a large scale. The mill is nearly completed and an electric hoist will be installed to enable development to ~ontinue and ore to be ex­ tra.cted to the full capacity of the mill, which is said to be about 150 tons a day. On the 300-foot level, crosscuts have been run for 800 feet at 100 foot intervals, which show fro'm eight to eighteen feet of ore, averaging in copper, lead, gold and silver, about $24 to the ton. L. Hoffman is gen­ eral manager. CALIFORNIA.

The Uncle Sam mine, near Kennett, Shasta county, is being actively developed under the management of Harry D. Staley. This is an old-time producer with a r~ord output of two millions and a dividend dis­ bursement of $600,000. The management now has 300,000 tons of $5 to $6 ore ready for extraction and milling. The ore ~an be mined and treated at a cost of $2.50 a ton. A new ten-stamp mill was recently installed on the property. The mine is developed by a 1,2'DO-foot tunnel, which gives 600 feet of backs, and depth is being rapidly attained as the tunnel is extended into the mountain. The ore is moved from the mouth of the mine to the mill by gravity, a distance of 150 yards. COLORADO.

On the 1,400 west level of the Old Town, it Idaho Springs, four feet of $50 ore is be­ ng opened up by lessees. During February, 104 cars of ore and :oncentrates were shipped from Telluride ,tation, a considerable gain over the ship­ nents of a year ago.

D. H. Burlingame, manager of the San­ tiago mine, in gast Argentine, is shipping $50 ore regularly, and will increase the ton­ nage as soon as the Argentine Central rail­ way is opened. 'The Liberty Bell, in the Telluride dis­ trict, is the first company in Colorado to cyanide its cO'lcentrates. Hereafter only bullion will be shipped, as is the practice with th'3 Alask,l-Treadwell, in Alaska, and the Goldfield Con, at Goldfield, Nevada. The Primos Chemical company has in­ stalled a five-ton electric motor and ten two·ten cars for use on its tramway be­ tween t,he mines and mili at Lakewood. The line is three miles long, and the power is furnish'~d by storage batteries. At a depth of 110 feet in the 1905 shaft of the Boulder Tungsten Production com­ pany, at Nederland, a streak of ore was struck which contains 30 to 40 per cent tUngsten. Much of the shaft has been in low grade, and it is the opinion in the dis· trkt that 'better ore will be found at depth. D. D. Shirley is forming the Dividend: Gold Mines company to take over the Black Jack and Linden mines at Black Hawk. The Black Jack has two shafts, 120 and 140 feet deep and a 100-foot tunnel connocting. T'his tunnel is in ore of an excellent grade. The mine is completely equipped for oper­ ating. At No. 3 shaft on the CamIJ Bird, at Ouray, ore has been reached in the 6th level, which proves the still further down· ward extension of the vein which the com­ pany has been recently developing. The ore is wider than above and the values hold. It is evident that the Ca;mp Bird is by no means dead. The mine has come back be­ fore, when it was feared that the end of its long career had been reached. The Oro-Cashier Mining, Milling & Power company, is opening a group of mines at Ophir, under the supervision of E. H. Van Endert. There are 'many openings on the mine, and a large amount of development is proposed. A sample of 600 pounds re­ cently treated at Denver returned values of about $35 a ton. Water is plentiful for mill­ ing, and a mill is so()n to be .installed, the equipment having been decided upon. The officers of the company are: E. H. Van Endert, president and general manager; W. O. Beckman, viee-president; G. C. Weber, secretary; A. M. Van Endert, treasurer.

A six-foot shoot of high grade copper ore was encountered on the 300-foot level of the Carmen Creek Mining company's property, near Salmon. J. W. Halcombe is manager of the company. The Pittsburg~ldaho, at Gilmore, con­ tinues to send out 100 tons of ore daily. The Gilmore property shipped seven cars in February. The tunnel being driven on these two properties is progressing satis· factorily. Two shifts are being worked at the Wilbert mill, in the Dome district, and about 65 tons of ore are ,being handled per day. When more water is available the tonnage will probably be increased to 100 tons, and it is possible that the mill will be enlarged to treat 150 tons. Develop­ ment in the mine is stated to be satis­ factory, An assessment of one cent per share against the capital stock of the National Copper Mining company near Mullan, Idaho, has been levied ,by the directors. The board will continue the present sys­ tem of development in the lower tunnel. The cash derived from the assessment will be used in continuing this work and to open up the ore body for stoping operations as fast as possible. Oscar and Anker Amonson and George Hanson report a strike of rich gold on their Hi-gh Bell group of claims, near Salmon, on Little 'Eight Miles. The ore was found in one wall of a tunnel which the owners were driving. The ore is mainly bromide of silver and gold. Trans­ portation of the ore to the railroad will be easy, if the discovery opens up into an orebory of commercial size. Machinery is still being forwarded to the Bohannon Bar Dredging company, which has 3,600 acres of ground ten miles east of Salmon. The dredge will cost about $140,000. The buckets are five cubic feet capacity. There are sixty ,buckets on the chain. The yield of the ground is expected to be about fifty cents a yard. J. F. Ryan, of Marysville, California, will have charge of the installation. Work is to be resumed on the Bell mine in the 'Coeur d'Alenes, near the Morning and the Frisco. Directors of the company recently levied an assessment of one per cent against the 5U,000 shares out­ standing, whiCh will provide a fund of $5,­ 000 for immediate use. The assessment is due March 12 and the officials anticipate ready response to the notices sent to stockholders. The mine, owned by the Finch-Campbell interests and Youngs­

The Red Monarch Mining company has t"ken over five claims in the Beaver min· ing district of the Coeur d'Alenes, adjoin· ing the Callahan and in the same neigh· ·borhood as the Idora Hill, Senator Clark's Sunset, and other rich properties. Con· siderations aggregating $50,000 are involv· ed in the transfer. Ralph Smith has been elected president; .K J. Lippert, vice presi. dent. and H. Bernard secretary·treasurer, all of .spokane, Washington. Controlling interest in the Flynn grou! of mines, in the Coeur d'Alene district, lying on the crest of the diviue uetween Gem and }fuIlan, and adjoining both the Morning and Frisco mines, has been se· cured under a two·year ·bond for ~150,0(}O by the Federal Mining company, accor.ding to advices received from Wallace. The deal was closed by Harry L. Day, president and general manager of the Federal, and the Flynn company has been reorganized, with Mr. Day as its head and Ramsey Walker as treasurer, while Joseph Whalen is continued in office as secretary. A sub· stantial payment has been made to the former owners of the property, all of whom are pioneers of the Coeur d'Alenes, and there is no doubt but the bond will ·be taken up before its expiration. Plans al· ready outlined for the development of the property contemplate extending the mill level of the Frisco mine, now in 1,800 feet, 2,000 feet further east through the Grover .Cleveland, one of the Frisco group, to tap the Flynn ore bodies at from 2,000 to 2;500 feet.

The Butte & .superior is treating 600 tons a day at a profit, but the second sec· tion of the mill will not be ready before another month. H. R. Hanson, of Butte, and Joseph J. 'WaIl, of Boston, have been added to the directorate Of the Butte Central, which is operating a new 125 ton mill at Butte. The Elkhorn Mining company has been incorporated by H. A. Frank. Chas. E. Gruwell, W.P. Cary and James E. Higgins of Butte and A. O. Heywood of Helena. The capital stock is $1,000,000. The independent companies in the B.utte camp will probably take advantage of the agreement with the miners which automatically reduces wages to $3.50 when 90pper falls ·below seventeen cents. Development on the May Day Mining company's property, at Radersburg, will be continued with an increased force and new equipment will be purchased. George A.

Development has been suspended on the 1,900·foot level of the Colorado shaft of the Davis·Daly, at Butte, as conditions did not warrant further search for ore in that section. Work will be concentrated on the 1,200 and 1,400 leve:s, in expecta· eOn of finding ore there. The output of copper tor the Butte dis· trict in February was 21,717,130 pounds compared with over 26,000,000 in January.

The Big Eight group of mines, consist· ing of three claims, adjoining the Band B 'group, controlled by the Greenough inter· ests, near Troy, has been purchased by Harry L. Day, president of the Federal Mining company, for $50,000, the sale be· ing based on five cents a share, for the issued capitalization of 1,000,000 shares. The Big Eight group was owned by the Greenough interests, J. D. Finley, Edward McCaffrey and other .spokane, Washing· ton, men, who recently secured control of the property through the purchase of an extensive ·block of stock from E. L. Tate. Whether the properties were taken over by Mr. Day individually or for the Federal company can not be learned, but in view of extensive purchases made by the Federal in the last few months it is beEeved to be a company transaction.

----0---­ DEATH OF PROMINEN.T MINING MAN.

George E. Gunn, who had extensive min­ ing interests in the west, died suddenly at the Hotel Utah. Salt Lake City, March 11. Mr. Gunn was born at Mientor, Ohio, fifty years ago. About twenty years ago he be­ calme identified with mining and smelting in Montana. and about a decade ago became interested in the Ely. Nevada. district. While field engineer for the American Smelting & Refining company, he became aware of the possibilities at Ely, and later became the owner of the Cumberland Ely mines. He then became interested in the Yerington district in Nevada, taking over the Mason Valley. and partiCipating in the formation of the smelting company which has the flourishing custom smeltery at ThO'mpson. With the formation of the Gunn-Thomp­ son company his interests widened. This company 'brought out the Inspiration Copper company of Arizona, which was recently taken over by Amalgamated interests. The company now controls the Mjagma Copper company in the same state. Other com· panies owned by this fir'm are the Hack­ 'lerry in Arizona, the Barker in Montana, and the Gunn-Quealy coal mines in Wyom­ ing. William B.Thompson. of Thompson, Towle & company. was associated with Mr. Gunn. Besides being an engineer of great ability. and a successful mining operator, Mr. Gunn was one of the organizers of the National Copper bank in Salt Lake. and was slated for a high office in the organization at the time of his death. His philanthropies were widespread, though secret. He died wealthy, but his properties, none of them. had reached full fruition. so that his death took him off on the real threshold of ilis succeSs. His demise is regretted 'by all with whom he came in contact, and is a distinct blow to the mining Industry. Mr. Gunn was a bachelor. and leaves sev· eral brothers.

1913. BINGHAM MINES COMPANY.

The report of the Bingh'am Mines com­ pany for the past year has been received. The indebtedness of the Bingham. Utah, company has been reduced to $455.000. The company made earnings of $138,113 in 1912. The payment of dividends by the Eagle & Blue Bell. of the Tintic district. is of great assistance to the Bingham Mines company, which holds the stock. Mana1$er Imer Pett, In his report. says: "A summary {If development work at the Dalton & Lark mine for the year shows a total of 1,953 feet of drifts, crosscuts. raises. and winzes. Not all of this wor,~ has been productive. but some new' ore bodies have been opened and partially de­ veloped. The main shoots were exploited, yielding a large tonnage, and a reserve is left for the ensuing year. The Brooklyn and Lead mine have been the most liberal producers. while the Lark vein has yielded a small tonnage of bigher grade ore. As in the past. it is planned to continue ex­ tensive development work in the unexplor­ ed sections of the three well-known veins. "On account of foul air and the strike of miners, the Commercial 'was operated for only seven and one-half months. "Mining was mostly confined to the ore developed above the 330 level. About 75 per cent of the territory of No. 2 shart has been productive from the 330 level up to the old Lower CommercIal tunnel. No new ore was developed west of the shaft. and the reserve above the '150, level west has been exhausted. The downward ex­ tension of the ore body was exploited on the 360 and 500 levels east. yielding a large and profitable tonnage, but the aver­ age metallic contents of the ore developed on these levels is too low to work profit­ ably at this time. A change is noted both in the structure and contents of the vein at this depth. On the 30, a north and south fissure was followed a distance of eighty feet, developing high-grade copper_ "The high productiveness of the terri­ tory above the 330 level warrants further development belOW, ,and this will ,be un­ dertaken as soon as the operating force is up to normal. "Total new development work for the year consists of 986 feet of drifts, cross­ cuts and raises." ~",,--o---
