MEXICO MINING NEWS 1929

MEXICO  MARCH 30 1929

It is understood that the Mexico Mines of El Oro will discontinue operations at its mines at El Oro, Mexico, although development will be continued at its property at Catorce, San Luis Potosi, Mexico. In addition to the development program at Catorce, treatment of the tailings from the old mill will be undertaken.

The company, which is under the direction of T. H. C. Mitchell, general manager, El Oro, has erected a preliminary plant of 100 tons daily capacity, which will be increased to 1,000 tons daily, if further operations prove successful. Sir Park Golf, 128 Gresham House, Old Broad Street, London, England, is president.
===
The Cusi Mexicana Mining Company, with properties at Cusihuiriachic, Chihuahua, Mexico, reports for the year 1928 an operating profit of $874,358, and a net profit of $278,227, after making deductions for depreciation, unproductive prospecting and loss through fire. The latter figure compares with $145,471 for the year 1927.

The gross income through the sale of concentrates was $997,604, and the expense of operating was $628,245. The company had on hand at the close of the year, current assets totaling $250,459, of which sum $126,340 was represented by cash, and current liabilities amounting to $85,857. The surplus account shows $526,954, including the net of $278,227, for the year 1928.
--==---===
H. C. Dudley, 704 Lonsdale Building, Duluth, Minnesota, president, states in his report to the shareholders that the Santa Marina shaft, which was burned from the Providencia level, to the surface, has been completely re-timbered, and is again in operation.

He also states that as much ore has been put in sight by development as has been extracted during the year.  W. G. Swart, consulting engineer for the company, reports that the company milled 81,472 tons of ore during 1928, as compared with 47,976 tons in 1927, and 37,151 tons in 1926.

The shipments from the mill consisted of 7,481 tons of lead concentrates and 5,698 tons of zinc concentrates during last year, and, in addition, 493 tons of dump ore were sent from the property. It is stated that there is about one year’s ore supply blocked out and partly broken in the stopes.

Two sulphide veins, unknown before, have been cut in the old workings south of the Cusi fault, both of which are said to be producing average ore. A tunnel run on the San Miguel vein is reported to have been extended for its entire length of 250 feet in oxidized ore.
===
Silver-lead ore, carrying values in copper, is reported to have been struck on the 200-foot level of the North Cananea Mining Company’s property at Cananea, Sonora, Mexico.

The ore was discovered in crosscut No. 2 in the Las Peñitas shaft. Crosscut No. 1, which is expected to shortly intersect crosscut No. 2, has been extended about 70 feet. C. W. Gabrielson, Box 279, Bisbee, Arizona, is president of the North Cananea, and C. C. Newens is superintendent.
===
It is reported that the San Francisco mine, in the Sierra Juarez district, and the Conejo Blanco mine, in the Taviche district of Mexico, have been sold to a group of Alabama capitalists by the former owners, R. Wilson and Finney Bacon. The San Francisco mine has been idle for the past 20 years.
===
Negotiations are being made for the continuance of an automobile road from Durango to Mazatlan, Sinaloa, by the way of El Salto, Durango, it is stated. This would facilitate matters in the transportation of ores to the newly constructed lead smelter at Mazatlan, and furnish an outlet for production from that region.
====
It is understood that operations may soon be resumed at the old Dicha mine, located near Acapulco, Guerrero, Mexico, which has been idle for some time. At one time the construction of a railroad was started to the properties from Acapulco.
====
Difficulty is being experienced by the Cananea Consolidated Copper Company, it is stated, in securing powder for use in operation of its mines at Cananea, Sonora, Mexico, because of the Mexican revolution.

An embargo has been placed on all explosives entering Mexico, and it is understood that the Southern Pacific Railroad is accepting no shipments of this product.
===
The Sabinal Mining Company, recently incorporated under the laws of Arizona, has opened an office in the Nebhan Building, at El Paso, Texas.

The company is at present operating and developing its properties, which are located in the Sabinal district, near Ascencion, Chihuahua, Mexico, and which include the Azteca and Florencia mines.

The Azteca consists of nine pertenencias, or about 22 acres total area, and is said to be producing ores carrying good values in lead and silver. This mine is well equipped with a gasoline hoist headframe, hoist house, and quarters for workmen.

The Florencia property consists of 10 pertenencias, or about 25 acres total area, and is a producer of silver.

A mill site with water rights and a tailings disposal location has been secured by the company, and in the near future, a new flotation plant of 30 tons daily capacity will be erected to concentrate the ores that have not sufficient value to warrant direct shipment to the smelter. The mill will be designed, so as to be easily increased in capacity.

In general, the Sabinal Mining Company proposes to operate the Azteca mine, ores from this mine to be treated in a mill built for that purpose, and the proceeds from the mill operations to be used for the development of the Florencia property.

The concentrates will be shipped to the El Paso smelter. Officers of the company are: B. E. Bryant, president and general manager; B. B. McClintock, vice-president; A. L. Bryant, secretary and treasurer, and G. H. Tisdale, superintendent.

CALIFORNIA-AHUMADA REPORTS DEVELOPMENT PROGRESSING

Good progress is reported being made by the California-Ahumada Mining Company, H. A. Houser, president, with main offices at 646 First National Bank Building, El Paso, Texas.

The company is said to be amply financed, an arrangement having been concluded with the Pardners Mines Corporation of New York, whereby that company is to buy the entire stock remaining in the treasury, amounting to 400,000 shares, at 25 cents a share, having deposited, for the first 200,000 shares, $50,000 cash in the bank to the credit of the California-Ahumada company on November 1, 1928.

The Pardners Mines Corporation is to purchase a second block of 100,000 shares at $25,000 on June 80, and 100,000 shares on November 30, 1929. In addition, the Pardners company has an option to purchase a block of 180,000 shares before April 17, 1930, at 85 cents a share, and 171,000 shares at 90 cents per share by October 17, 1930.

Properties of the California-Ahumada Mining Company are located in the Cerros Cobrados Mountains, in northeastern Chihuahua, Mexico, and consist of the La Gloria, Esperanza, California, Ampliacion de Gloria and Anexa de Gloria claims.

About 485 tons of ore, containing values in silver, lead and copper, have recently been shipped from these claims, the gross value of which is estimated at $16,212 72, or an average of $85.82 per ton, the net profits amounting to $9,233.67, or $20.17 per ton.

Within the last few months, the company has installed new equipment and machinery, including a new hoist and compressor. A complete camp has been established on the La Gloria claim, and office buildings, a warehouse, and employees’ homes erected, and a road built.

A 75-foot tunnel has been driven on the Esperanza claim to tap the fracture on the La Gloria claim.  On the California, a hoist has been installed, and a shaft sunk along the dike, which at a depth of 30 feet has a favorable showing of lead ore.

It is estimated that there are about 10,000 tons of ore, similar to the grade shipped, blocked out in the mines. Forty-five men are employed on the ground, working three shifts daily. Edward Salveson is superintendent, and W. M. Benham, geologist.

Since the new equipment was installed the first of the year good progress has been made. The shaft has been sunk to a depth of 225 feet, and station cut at the 165-foot level. At the 65-foot level, the south drift has been extended 200 feet, and the north drift 225 feet.

THE MINING JOURNAL  JUNE 30 1929

MEXICO MINING NEWS

A strike of silver ore has been reported recently made in the Niñita mine, which is located near Sabinal, Chihuahua, Mexico. At the end of the 300-foot tunnel, a winze was sunk 85 feet in solid limestone, and entered into a contact of porphyry, it is stated.

A sample of ore from this contact, assayed in El Paso, Texas, is understood to have averaged 80 ounces. With further drifting on the contact, samples were taken at intervals of 20 feet, which assayed 100, 200 and 240 ounces silver to the ton.

A. V. de Pascale, Albino Garcia, Dr. S. Haffner and Leopoldo Iwonski, who may be reached at Box 417, El Paso, Texas, are owners of the Niñita.
---====----
Work is scheduled to be resumed at holdings of the Ampliación de Florencia Mining Company in July, operations having been suspended for several months due to the unsettled conditions in Mexico.

The claims are located at Sabinal, Chihuahua, Mexico, A. V. de Pascale, Box 417, El Paso, Texas, president and general manager.
---====----
Property of the Sierra Madre Exploration Syndicate at Soyopa, Sonora, Mexico, is being developed by adits and shafts with Bulkeley Wells in charge as general manager.

According to Fred H. Dakin, consulting engineer, the holdings are expected to be put upon a producing basis very shortly, the values being in gold, silver and lead.

Regular mine work requires the services of 30 men. Headquarters of the company are located at 1408 Hobart Building, San Francisco, California.
---====----
A new company, to be known as the El Sol Mining Company, has been organized by H. A. Houser, president, B. Knight Smith, vice-president, H. B. Waud, treasurer, and W. T. Houser, secretary, with main offices at 662 First National Bank Building, El Paso, Texas, for operation and development of properties near Villa Ahumada, Chihuahua, Mexico.

The company, which is capitalized at $1,500,000, has acquired the Hija del Sol, Estrella, La Mexicana, Seguridad and La Abundancia claims, two of which, the Hija del Sol and Estrella, adjoin the California claims of the California-Ahumada Mining Company and lie less than a mile from property of the Mosqueteros Mining Company.
---====----
Preliminary work has already been started on the Don Carlos, Anexas a Don Carlos, and Ampliación de Don Carlos properties, recently taken over by Ralph C. Nowland, mining engineer of 1800 Hobart Building, San Francisco, California, and Durand C. Hall, mining geologist, the new organization to be known as the Aztec Mining Company.

It is reported that an ample development fund has been subscribed by mine operators of the coast, associated with banking interests of New York. The properties adjoin the Gloria and Esperanza claims of the California-Ahumada Mining Company, near Alcaparra, Chihuahua, Mexico.
---====----
A 500-ton concentrator, employing flotation, is being constructed at the old San Carlos mine, located in the State of Chihuahua, Mexico, by the Victor Mining Company, which is controlled by Frederick Velie of Kansas City, Missouri. A road has been built to connect the mine with the station of Chato, on the Orient railroad, 30 miles distant.
---====----
News is current that field engineers have lately been at the Silver Plume mine, near Cananea, Sonora, Mexico, working with staff engineers of the Minaret Consolidated Mine Company, on final details covering the installation of heavier mine machinery and the construction of a 50-ton milling plant.

C. C. Randall, 107 North Lemon Street, Anaheim, California, is general manager of the Minaret company, now operating the Silver Plume.
---====----
Development work, as well as production, is active at the properties of the Cusi-Mexicana Mining Company at Cusihuiriachic, Chihuahua, Mexico, of which H. C. Dudley, 704 Lonsdale Building, Duluth, Minnesota, is president.

The diamond drill, which has been installed on the 1,000-foot level by the E. J. Longyear Company to explore the area north of the Cusi fault, is operating two eight-hour shifts daily. The drill will be driven toward the west at an angle of 60 degrees downward, and to the east at an angle of 80 degrees downward.

The Santa Marina and the San Antonio veins, on the south side of the fault, running directly north, are presumed to have been cut off by the fault, and the extensions of the veins are expected to present a broadside target for the drill.

A station is being cut at 1,150 feet in the Santa Marina shaft, which was bottomed in the vein at 1,060 feet. However, the vein dipped out of the shaft with increased depth, and after the station is completed, a crosscut will be driven to the enrichment, and drifting will be done both north and south.

The extent of the ore downward in the Santa Marina shaft has not yet been ascertained. The drift on the Santa Marina vein, south from the shaft on the 1,150 level, Is expected to carry development under the so-called big lead stope, which lies between the Green and Red faults, and to gain an additional depth of 150 feet.

This enrichment is said to extend well toward the surface, having a distance of about 220 feet on the bottom levels, and not having diminished as to size and quality of ore on the 1,000-foot level.

The drift from “A” level, south from the Red fault, and which is described as the extension of the combined Santa Marina and San Antonio veins, is being watched with much interest.

The drift, which is being driven to get under the old workings in the San Nicholas area, has lately cut stringers of ore, and it is proposed to explore this once productive area at much greater depth than was attained by former operators.
---====----
Near-future improvements to be undertaken by the Greene Cananea Copper Company on its holdings at Cananea, Sonora, Mexico, will include reconstruction of its crushing and sampling plants, the erection of new ore bins, and improvements to the railroad approach.

The capacity of the power plant is being increased by the installation of high-pressure direct-fired boilers and a 6000-k. w. turbine. New high-pressure waste heat boilers are also to be installed at the company’s reverberatory plant.

The additional power capacity will enable prospecting of the Sonora Hill area by underground workings. T. Evans is president and general manager, and L. A. Maule is purchasing agent.
---====----
The Jimulco mines at Estación Otto, Coahuila, Mexico, operated by the Compañia Minera de Peñoles, S. A., for the past five years, have been leased to John W. Beard of El Paso, Texas.

These copper mines, which are 50 miles south of Torreón, Coahuila, Mexico, are connected with the National Railway by a five-mile narrow-gauge line. George Butler, Jr. will be in charge of development work.
---====----
During the year 1928, the Neg. Minera San Rafael y Anexa., with operations at Pachuca, Hidalgo, Mexico, distributed dividends in the sum of $660,000, bringing the total dividends paid up to January 1, 1929, to $19,119,579.78.

During the year, the company treated a total of 228,250 tons of ore, with an average content of 445 grams of silver, and 1.99 grams of gold, representing an average daily tonnage of 725 tons, as compared with 641 tons the previous year. The extraction averaged 90.6 per cent silver and 92.6 per cent gold.
---====----
Ore from the property of the Security Copper Company, at Pitiquito, Sonora, Mexico, is understood to have recently assayed 16.8 ounces silver, 27 percent copper and $4 gold, running about $81.17 per ton. The ore was sampled at the sampling plant of the Chamber of Mines at Tucson, Arizona. M. M. Hickey is manager.
---====----
The Santa Gertrudis Company, Ltd. of Pachuca, Hidalgo, Mexico, milled 145,893 dry short tons of ore during the quarter ended March 81, 1929, according to reports of that company.

For silver sold, the company received an average price of $0.570, United States currency per ounce, .999 fine.

The total revenue for Santa Gertrudis, Inversions, and Dos Carlos, after allowing for development and participation of owners, but before depletion and depreciation, was $394,919. Capital expenditures by the Dos Carlos Company amounted to $11,020.
---====----
Three shifts are being worked by the Califomnia-Ahumada Mining Company, Alcaparra, Chihuahua, Mexico, in driving the drift and running the No. 8 crosscut on the 165-foot level, 25 tons of ore per day being produced from these two developments.

The drift has been in ore on all sides for 73 feet, it is understood, and the crosscut has been extended 19 feet in the same ore.

It is believed by company interests that the development of this property within the next six months will warrant the construction of a spur track to the Chihuahua y Oriente railroad, six miles distant.  

W. T. Rouser, with company headquarters at 648 First National Bank Building, El Paso, Texas, is manager and secretary.
---====----
Operations of the Fresnillo unit of the Mexican Corporation, S. A., at Fresnillo, Zacatecas, Mexico, will hereafter be known as The Fresnillo Company, effective from May 1, 1929.

Main offices of the company will be located at Edificio Woodrow, La Bolivar No. 18, Mexico City, Mexico, Hugh Rose, managing director. Thomas C. Baker is general manager of the properties at Fresnillo.
---====----
Following the installation of adequate pumping equipment, production is again coming from the No. 8 level of the Ahumada Lead Company at Los Lamentos, Chihuahua, Mexico, John M. Brooks, Villa Feliz U. Gomez, Chihuahua, Chihuahua, Mexico, general manager.

The pumping capacity of the mine has now been brought up to 2,400 g. p. in., and bulkheads are being put in the stopes to keep-the water back. Development above the No. 7 level has been dropped, and interest is now being centered upon exploration of the ore body from the No. 8 level.
¿¿¿
Construction of a Forrester flotation machine has recently been completed at the Tigre Mining Company, El Tigre, Sonora, Mexico, resulting in improved extraction. At the company’s 225-ton mill, located at El Molino, Sonora, Mexico, a Model D Dorr duplex classifier, was substituted for two Model C simplex machines.

According to General Manager R. T. Mishler, exploration work indicates that the bottom of the ore body has been reached no ore having been found on the No. 7 level of the Fortuna mine, which corresponds to the No. 21 level of the Tigre mine; and the Gold Hill enrichment, said to be continuous in both length and depth for 1,000 feet, has apparently reached its boundary lines at the thirteenth level.

Small ore bodies have been developed on levels 18, 14 and 15. During the year 1928, production amounted to 82,480 tons, resulting in a recovery of 9,684 ounces gold and 2,599,485 ounces silver.
---====----
At the Tiger Leasing Company at La Quemada, Jalisco, Mexico, which is also a subsidiary of the Lucky Tiger-Combination Gold Mining Company, difficulty in metallurgical operations has been experienced, and the company is considering the installation of an additional Dorr classifier and tanks.

Proven and probable ore reserves of this company total approximately 174,414 tons, believed to be sufficient to keep the 80-ton plant in operation for six or seven years at the present rate.

Additional tonnages are also expected to be developed in the west end of the 400 and 500 levels. W. A. Wasley is general manager of the Tiger Leasing, and T. R. Herndon is mill superintendent.
---====----
A new baghouse and a sintering plant are being added to the lead smelter of the Cia. Minera de Peñoles, S. A., at Torreón, Coahuila, Mexico, A. J. Halbcrt, superintendent. The plant has a capacity of 400,000 tons of charge per year.

At the company’s Achotla unit at Tamixco, Guerrero, Mexico, J. F. Thorn, superintendent, changes are being made in the method of treating the silver-lead-gold ores. Hereafter an all-brine leaching method is to be used at the 800-ton plant in place of cyanidation.

George H. Harbordt, with headquarters at Apartado 251, Monterrey, Nuevo Leon, Mexico, is general manager of the Peñoles company.
---====----
Ore has been proven for a length of 2,487 feet on the 340-meter level in the Cuevo Santa vein at the Mexican Corporation, S. A., now known as The Fresnillo Company, at Fresnillo, Zacatecas, Mexico, according to reports of the company. Approximately 1,837 feet of ore was also developed at a depth of 270 meters.

At 840 meters, the body averages five feet in width, and runs 10.8 ounces silver, 10.9 per cent lead, and 12.1 per cent zinc. The company’s General shaft has been enlarged and timbered to 340 meters, and a raise is now being put up from the 425 meter level.

Production has also been started from the San Nicolas area of the holdings. The mill is at present treating 2,500 tons of oxide ore and 400 tons of sulphide ore daily.
---====----
All preliminary arrangements have been made and the ground broken for the 800-ton milling plant to be constructed at Chihuahua, Chihuahua, Mexico, by the American Smelting and Refining Company for treatment of ores from the company properties at Santa Eulalia, Chihuahua. It is expected that this construction will involve about a year’s time.

At the new plant, the coarse crushing will be done in gyratory crushers and Symons cone crushers, and the fine grinding in rod and ball mills, each in closed circuit with the classifiers. Gravity and flotation methods will be employed in concentration.

W. M. Drury is general manager of the American Smelting and Refining Company, and at present maintains headquarters at the New York office of the company, 120 Broadway.

THE MINING JOURNAL for SEPTEMBER 30, 1929

MEXICO MINING NEWS

Satisfactory progress in development work is reported by the Sierra Pinta gold mine in the Altar district of Sonora, Mexico. The main shaft has been sunk to a depth of 700 feet, and continues in ore. Plans are underway to do some drifting at the 700 level.

S. Nixon, who is said to hold an option on the property, states that, while this ore is not as rich as commonly reported, it is of commercial value. All shipments are made by Ajo, Arizona. A. L. Richards, Box 647, Ajo, Arizona, is general manager, in charge of all work at the mine.
----
The Jupiter mine, an old Spanish “antigua,” is being reopened by L. 0. Skliris, mining engineer, Hotel Paso Del Norte, El Paso, Texas. Mr. Skliris purchased the mine from Alberta V. Sosa of Agua Prieta, Sonora, after a careful examination and sampling.

The Jupiter is in the Sierra Pinta Mountains, 55 miles south of Cananea, and is also near the town of Baviacora, on the Cananea-Hermosillo highway.

There are several thousand tons of ore on the old waste dumps, which Mr. Skliris reports as averaging around 100 ounces silver and one-ounce gold per ton.

For the present, work is being concentrated on the opening up of ore bodies disclosed when the shaft was unwatered. An adit tunnel, five feet wide by seven feet high, is being driven, which is to cut the vein at an approximate depth of 500 feet below the surface, and 310 feet below the 190-foot shaft, which was un-watered.

This tunnel is now in 150 feet, and the vein should be reached in 350 feet more of tunneling. It is estimated that this will be accomplished about the first of December.

The floor of the tunnel has a one per cent down grade to the portal for the future drainage of the property. The ore in sight in the lower workings is said to show a 20-inch pay streak, assaying 3,000 ounces of silver and 25 ounces of gold per ton.
---=
The Guadalupana Mining Company, according to an announcement by Dr. Carl Lee Smith, president, 339 First National Bank Building, El Paso, Texas, is to construct a 40-ton concentration and flotation mill.

This mine is six miles east of Tecoripa, and 100 miles southeast of Hermosillo, and 60 miles from Ortiz, the nearest railroad station, from which a good road leads to within three miles of the mine.

Considerable development is evidenced by the old shafts and drifts, from which a large quantity of high-grade ore was mined in former years.

Careful sampling indicated that both high-grade and milling ores in commercial quantities remain in sight, ranging from 7.5 ounces to 662 ounces silver, together with gold and lead.

Tests as to method of recovery have been made by the Southwestern Engineering Corporation and by the University of Texas, College of Mines. Principal development is on the 300 level, workings above the level are now largely caved.

It is estimated that there are about 1,500 to 1,600 tons on the old dumps, which can be profitably treated by concentration, and flotation. Water for milling can be obtained from wells three-quarters of a mile from the mine, and fuel, semi-anthracite coal, is found in abundance at San Javier, 80 miles distant. The present equipment consists of a steam hoist and small compressor.

S. H. Worrell, mining engineer, has recently completed a thorough examination of the mine.
--==
Cia. Minera. Borda Antigna y Anexa, near Tlalpujahua, Michoacan, Mexico, closed down the last of August, due to exhaustion of ore reserves.

This move had been contemplated for a number of months, as attempts to increase reserves had not been successful. Borda Antigua was operated by Cia. Mm, Las Dos Estrellas.
-===
Cia. Minera Las Dos Estrellas in El Oro y Tlahpujahua, Mineral Dos Estrellas, Michoacan, Mexico, continues to operate with a full force, although some difficulties are being experienced, due to the low grade of ore now being handled. This company mines about 2,200 tons of ore per day, employing an operating force of almost 3,000.
====
North Cananea Consolidated Mining Company, Cananea, Sonora, Mexico, is making plans for the sinking of its main shaft to the 500-foot level. This shaft is now down 380 feet.

Drifting on the 200 and 850 levels has given good results, it is said. C. W. Gabrielson, Box 2880, Bisbee, Arizona, is president of the company.
-===
Pittsburgh Vetagrande Mining Company, Zacatecas, Zacatecas, Mexico, J. C. Archibald, manager, is reported as mining at the rate of about 500 tons of silver-gold ore daily.

The San Barnabe mine, in the same district, has been un-watered under Mr. Archibald’s direction, and exploration work is in progress.
--==
The Fresnillo Company, Fresnillo, Zacatecas, Mexico, Thomas C. Baker, general manager, is understood to be obtaining very encouraging results from the development on the 425-meter level of the Cueva Santa vein, a good grade of ore showing over a three-foot width.

The ore shoot has been opened up for 600 feet, averaging 18.6 per cent zinc, 11.7 per cent lead, 18.9 ounces silver, and 0.8 dwt. gold. The sinking of the Saraos shaft to the 425 meter level has been completed, and skip-loading equipment installed. The mill is treating about 3,000 tons daily, of which 2,500 tons is oxidized ore.
--==--
A couple of American engineers from Zacatecas have gone to Northern Puebla, to have another try at reopening the old camp of Tetela del Oro; and are reported to have started in Los Canadas working with 100 men.

Tetela lies 9 leagues west of the station of Huitzizilapan, on the Teziutlan branch of the Interoceanic Railway in a rough, hilly country. The formation consists of limestone intruded by porphyry and contains several classes of ores.

Starting from the Santa Rosa mill as a center and the purely gold ores are found to the southwest and the silver ores to the east, both along zones of igneous lime contact.

The main ore bodies contain both silver and gold, and the chief modern enterprise on one of them was that of the Tetela Mining and Milling Company which was floated in London over 25 years ago for £200,000.

With the small fraction of this sum, that was not gobbled by the vendors and promoters, was built a concentration mill, and the Espejeras Antigua was partially reopened.

The ore chimney occurred in limestone near the igneous contact and shows pyrite, rhodonite and their oxides in quartz with a content of 600 grams of silver and 5 grams of gold.

The first adit driven by the Tetela Company struck the ore chimney where it had already been stoped; later the attempt to sink a winze from the adit was prevented by water; finally a lower adit was started but never reached the ore because of the bankruptcy of the company.

Since then the machinery has been sold for junk and nothing remains of the investors’ brave effort except roofless buildings, a flooded mine and a tailing dump, whose values were poorly extracted by a milling process ill-suited to the ore.

The chief gold mines are the companion Providencia and Aurora Antiguas. The gold here occurs in connection with pyrite blende, chalcopyrite, and arsenopyrite, and much of the ore evidently ran 1 to 2 ounces of gold.

The old workings are quite extensive and consist of open cuts, shafts, adits and stopes, which are now inaccessible because of water or caving. The ore bodies are sometimes quartz veins, sometimes contact lenses, but are irregular, both in form and gold content.

The Santa Rosa mill treated Providencia ore by amalgamation, and has a 50-foot waterfall yielding 21 horsepower. It is located three kilometers south of Tetela Village and has long been abandoned.

The latest activity here was a decade ago by Juan lbeken, a millman of Pachuca, who invested a decade’s savings in the construction of a little stamp mill and a silver-lead blast furnace. Ibeken later became manager and did some smelting, with the aid of imported lead, for account of his creditors.

Reports of the American Smelting and Refining Company, show a consolidated net income of $10,947,501 for the six months ended June 30, 1929, which compares with $8,219,451 for the first half of last year.

This may also be compared with a net income of $8,507,944 for the same period of 1927. The consolidated balance sheet as of June 30, 1929, showed current assets of $94,813,457, against $88,456,101 a year earlier; current liabilities of $23,642,762, against $17,706,323 on June 30, 1928, and net working capital of $71,170,695, against $70,749,778.

On June 30, of this year, the company had on hand, in cash, demand and time loans, and  U. S. Government securities, $26,668,743. This sum represented a decrease of $553,742, from the total of the same items at the end of 1928.

In this connection, President Simon Guggenheim points out that “cash on hand would have been materially larger had it not been for the revolution in Mexico, last spring.

While the company’s mines and smelters were operated during military activities, it was not possible to ship bullion out of Mexico, and thus the cash realization of metal values was delayed.” Operations have now become normal.

THE MINING JOURNAL  FOR November 30 1929

MEXICO MINING NEWS

Approximately 600 tons of ore per day is being mined by the Neg. Minera de San Rafael y Anna, at Pachuca, Hidalgo, Mexico, with production averaging 20,000 kilos of silver quarterly.

This compares with around 90,000 kilos produced last year. R. A. Conrads, is director general in charge of operations, assisted by Oliver Powers, mine superintendent, and L. W. Allen, mill superintendent.
-=-=-
A number of the smaller mining companies near Zacualpan, Mexico, Mexico, have resumed operations, employing the flotation method for treatment of the ores, and are now shipping concentrate to the San Luis Potosi smelter of the American Smelting and Refining Company.

Details are not yet available in regard to the 500-ton flotation plant proposed for erection by A. S. & P. at San Luis Potosi.
-=-=-=
According to Clement K. Quinn, 1050 Union Trust Building, Duluth, Minnesota, the Canam Metals, Ltd., is acquiring the Canam Mex Mines, Ltd.

In addition to Tri-state properties which will be taken over, the company is gaining control of mines at Zacatecas, Zacatecas, Mexico, one of the properties being known as the Farroquia, where important ore disclosures are said to now be in progress to the west of the shaft, in virgin ground, at a depth of 300 feet.  

East of the shaft, the mine is developed to a depth of 660 feet, with the workings bottomed in ore.

While installation of a 200-ton mill is considered as warranted by Ira B. Joralemon, the company’s consulting engineer, it is probable that mill construction will be withheld until further development has taken place. The ore is a primary sulphide, carrying copper, lead, zinc and silver.

Two other properties of promise in the same district, are the San Roberto and the Zarogossa, both of which are controlled by Zacatecas Metals, which is the Mexican holding corporation for Canam Metals. Operations are being directed by J. C. Archibald of Zacatecas.

Development work accompanying shaft-sinking on the Oliver Vein in the Silver Plume Mine of the Minaret Consolidated Mines Company, near Cananea, Sonora, Mexico, has uncovered a body of copper-lead-silver ore at a depth of 72 feet, according to current reports of Harry L. Seares of 511 Story Building, Los Angeles, consulting engineer. The shaft is double-compartment, and the ore is said to assay in excess of $82 per ton.

The work being prosecuted on the Oliver Vein constitutes a check on geophysical work recently performed by the Radiore Company of Los Angeles (a geophysical prospecting concern), which, it is stated, has outlined conductive ore bodies over a horizontal distance of 1,500 feet.

The company expects to take an appreciable tonnage of ore from this source, in addition to the volume being mined from the main workings, and treated in the new 50-ton flotation plant, which went into commission the middle of this month.

MEXICO

During the month of March, 1929, mining companies of Mexico paid total dividends amounting to $1,509,947.

This amount was made up of the regular quarterly dividend of 75 cents per share paid on common stock by the American Metal Company, Ltd., operating in the United States and Mexico, totaling $484,947; and the preferred-stock quarterly dividend of $1.50, paid by the same company, amounting to $150,000; together with the regular quarterly dividend of $1.75, totaling $875,000, paid on preferred stock by the American Smelting and Refining Company, also operating in both countries.

The last quarterly dividend paid by the American Metals Company, Ltd., on common stock, at the same rate, amounted to $446,127, while the preferred-stock dividend was a duplicate of last quarter. The quarterly dividend of the American Smelting and Refining Company, on preferred stock, remained the same for the last quarter was paid in December, 1928.
---====----
C. W. Gabrielson, Box 279, Bisbee, Arizona, reports that crosscuts on the 200-foot level of the main shaft of the North Cananea Consolidated Mining Company’s property at Cananea, Sonora, Mexico, have cut five separate and distinct veins, and that two of the crosscuts are now running into silver-lead ore, averaging around $100 per ton.

Intensive development is under way at the North Cananea holdings, following a campaign of diamond drilling. Mr. Gabrielson is president of the company.
--===---===
For the year 1928, the Santa Gertrudis, Ltd., with properties at Pachuca, Hidalgo, Mexico, reports a net income of $897,867, before deduction for depreciation and depletion, as compared with $520,098 in 1927.

From the company’s various properties, a total of 163,251 dry tons of ore were mined during the last year, which compares with 181,880 tons during 1927. The average price received from sales of silver in 1928 was $0.5822 per ounce 999 fine.
--==---===
The annual report of the American Smelting and Refining Company shows a net income, after depreciation, depletion, interest, federal taxes, and preferred-stock dividends, of $18,586,203, which is compared with $15,477,769 in 1927, and $17,-760,721 in 1926.

During last year the company paid dividends totaling $8,989,820, against $8,379,840 in 1927. The company’s new lead refinery at Monterrey, N. L., Mexico, is expected to soon start operations, and gives promises of substantial profits.

In addition to the company’s present holdings, further expansions are also under consideration. At the close of 1928, a special distribution of 8 per cent of the year’s salary was made to all salaried employees in the service of the company throughout that year.
--==--===
Purchase is being made of new hoisting equipment, an air compressor, and machine drills by the Silver Plume Mining Company, to be used in shaft-sinking and development of the company’s Olive Vein.  

From this source, Morris B. Parker, of Hollywood, California, who is general manager, states that 768 tons of ore have been milled, experimentally, at a neighboring reduction plant, with a recovery of 92 per cent of the assay value of the mill heads, and a smelter return of $14,247 from the concentrates.

Arrangements are being made to equip the property with a 50-ton flotation plant, which is expected to be put in commission within the near future.

At the present time, it is understood that two carloads of $60-ore are being mined, which will be consigned direct to the smelter. Harry L. Seares, 511 Story Building, Los Angeles, California, is consulting engineer for the Silver Plume whose properties are located 26 miles east of Cananea, Sonora, Mexico.

In his report to the Ahumada Lead Company, John W. Brooks, Jr., manager of the Cia. Minera de Plomo, S. A., the company’s subsidiary at Los Lamentos, Chihuahua, Mexico, states that the total output of lead for the year 1928 was 12,854,809 pounds.

The average price realized by the company was 6.29 cents per pound. Production was much less in 1928 than in 1927, the total output of lead the previous year being 24,865,705 pounds.

The total production to date of December 81, 1928, was 142,295,155 pounds of lead, 1,626,882 ounces of silver, with 806,209 dry tons shipped.

A number of things are said to account for the less production in 1928; one being failure to encounter commercial ore in extensions of old ore shoots; the inability to mine on the eighth level, owing to the necessity of providing better ventilation through a connection with the surface; re-adjustment of the old pumping equipment and the installation of a new pump, and the lower prices of metals.

The new pumping equipment provides a capacity of 2,400 gallons per minute. Indications are that a substantial quantity of ore will be mined from the section between the seventh and eighth levels.

Work has been discontinued temporarily on the company’s Perdido claim, while operations have been suspended indefinitely on the Sonora, Lois and Sorpresa claims.

All development work and the greater part of the stoping is done on a contract basis. A force of about 197 men is employed under the direction of Mr. Brooks, who has headquarters at Villa Felix U Gomez, Via Lucero, Chihuahua, Mexico.
==---====--
It is understood that the Erupcion Mining Company, with properties at Los Lamentos, Chihuahua, Mexico, has become interested in the Mosqueteros Mining Company, on a 50 per cent basis, and will prosecute development work with a view of opening up new ore bodies.

During last year the Erupcion Company shipped around 1,557 tons of ore in seven months, recovering 698,356 pounds of lead, and 9,868.49 ounces silver. Income from sales of lead and silver was reported to be $62,488.17, with expenses of $92,117.06, making an operating loss of $29,688.89.

Approximately 989 feet of drifts and crosscuts, and 260 feet of raises and wines were driven. George H. Cobbe, 759 First National Bank Building, El Paso, Texas, is secretary of this company.
--===---===
The La Campana mine, located in the Altar district of Sonora, Mexico, is being reopened under the direction of J. E. McIntyre, mining engineer of Chicago, it is stated.

This mine, of which E. E. Pope of Parkersburg, West Virginia, is one of the principal owners, has been idle since 1912. It is a gold-silver property.
--==---==
The Moctezuma Copper Company, operating properties at Nacozari, Sonora, Mexico, H. H. Horton, manager, reports for the year 1928, a production of 818,416 tons of ore, compared with 795,958 tons in 1927.

Development work consisted of 29,495 feet of drifts, raises, and winzes. A total footage of 16,218 feet was drilled, of which 10,781 feet were drilled as stope development work.

This diamond drill work was successful both in finding net ore and in extending known stoping areas. At present, development of the nineteenth, twentieth and twenty-first levels is actively in progress.

The Pilares ore body, at the south end of the mine, has been encountered on the nineteenth level, but its extent and copper content are not yet fully known.

Drifting and diamond drilling on the Porvenir vein, outside of the Pilares Oval, failed to disclose the existence of commercial ore, and work has been discontinued at this point.

In stoping methods, an increased tonnage was mined during the year by inclined cut-and-fill, and a decreased tonnage by flat cut-and-fill and shrinkage methods.

At the concentrator, experimental work on a bowl classifier unit gave favorable results due to the better classification and finer grinding accomplished.

Although several outside properties have been examined and considerable work done, no commercial ore has been developed, with the exception of a small tonnage of gold and silver ore on the Margarita vein of the Churunibabi group.

Work is reported to be progressing in a promising way at holdings of the Altar and Cananea Mining Company, located in the Altar, Sonora, Mining District of Mexico, drifting being done both ways from the main shaft, at a depth of about 220 feet. The mines are being worked with engines, equipped with air compressors, making machine-drilling possible.

The holdings consist of 10 claims, which cover a total area of 824 acres. George Young, 927 East Sixth Street, Tucson, Arizona, is secretary-treasurer.
