'" " .. , " •• 'me," Bethlehem Superior Hollow Drill THERE are neither pits nor hairline cracks in the smooth inner walls of Bethlehem Superior Hollow Drill Steel. There is no weak point for fatigue stresses to drive an entering wedge and cause early rod failure. That's one of the biggest reasons why Bethlehem Superior is turning in such a remarkable record for drilling economy in major mining areas and large construction jobs throughout the country. The entire inner surface of Bethlehem Superior Hollow Drill is utilized to absorb the terrific pUnish4 ment of modern drilling. Get complete facts on Bethlehem Sup& rior Hollow Drill Steel. It is being used from coast to coast. It is tough, easy to heat.treat, the kind of sleel that means real drilling economy on any job.

San Franci.co Gold King mine, oPerated' by C, O. Mittendorf, Box 321, Randsburg, California. The Mountain King gold mine at Hodson, via Copperopolis, California, has suspended operations. The shutdown, which affects about 55 men, is said to be due to a strike at the smelter. W. B. Phelps, 1494 Brae Bum Road, Altadena, California, is general superintendent, and L. V. Chancellor is mine superintendent. The property is operated by the Jumbo Con.olidated Min4 ing Company. Robert W. Lea, vice4president of the Johns4Manville Company of New York, and Spencer Grant of Grant Birkholm and Company, Inc., 206 Sansome Street, San Francisco, California, have leased, on a royalty basis, 326 acres of ground in the Panoche district near Hollister, California, with a view to extensive quicksilver mining operations should the property prove sufficiently rich in the ore. Lily Berg of Hollister is the owner of the ground. The property has never been worked and E. H. T. Mitchell, mining engineer of San Francisco, is in charge of a crew of three men engaged in preliminary testing. James Fitzhugh of Alturas, California, is reopening the old Gearhart mine on Indian Creek about 10 miles north of Happy Camp, California. The property was pur4 chased from Lon Collins, Sam Sargent, Carl Adamson, Henry Erhart, and Genr Newton. It is comprised entirely of un4 explored ground and will be worked by hydraulic mining, following completion of the ditch system to supply water for the giant. 'One and one4half miles of road to the mine were constructed in July from the McClimans ranch on the South Fork of Indian Creek. O. T. Dennhardt, 4565 Oregon Street, San Diego, California; John Wilson; and A. E. Place of Nelson, Nevada, have leased the Noble mines in the Laguna Mountains, Pine Valley District, San Diego County, California. The property has been tied up in an estate and has been idle for over 20 years. Work has been started on a small scale with Dennhardt in charge. Eight and one-half to 10 tons of ore are being shipped daily from the Monte Cristo mine near Mammoth Lakes, California, to the Mineral Reduction mill near Benton Station with encouraging recovery values reported. C. A. and Raymond Collins and associates began prospecting work on the property in 1937, and recent development has disclosed a vein which had been lost by former operators. The mine is opened by a 1,550-foot tunnel driven in earlier operations. A crew of 12 men is employed under the supervision of Raymond Collins, Bishop, California. F. F. Thompson, 600 South Sullivan Street, Santa Ana, California, and his partner, Vaughn Maynard, also of Santa Ana, have reported discovery of a five-foot vein carrying commercial tin ore at their mine 40 miles east of Baker, California, and about seven miles north of Cima, California. The property was formerly known as the Bernice claims and was worked two years ago by C. E. Hammett and Trig Button just prior to being taken over by the present owners. W. C. Nichols, Bank of America, San Francisco, California, is operating the Centennial placer mine on the Klamath River near McConnell Bar, using a dragline trommel, and sluices. John Vogler, Klam: ath River, is in charge. The Submarine Mining Company, A. W. Wickman, manager, Stockton, California is working the K. S. S. property on th~ Tuolumne River above the Stevens Bar bridge. A diver, working on the river bot- tom, directs the suction nozzle of a Six4 inch gravel pump. The operators plan to construct a $6,000 floating boat to carry their surface equipment. It is estimated that five years will be required to work out the ground under lease. Associated with Wickman in the enterprise are Ben Lamping, W. H. Farren, and Bert Knapp . Extensive changes are being made in the milling plant of the Central Eureka Mininl Company, James Spiers, superintendent, Sutter Creek, California. The 40 stamps are being reduced to 20, and the battery screens are being increased to four-mesh for preliminary grinding. A new six by seven Joshua Hendy ball mill then takes the pulp and grinds to 60 mesh, working in conjunction with a multi zone Dorr clas· sifier fitted with a 12-foot bowl, which effects a better separation of finer grind4 ing. The new plant will have a capacity of 200 tons per day. The present plant is treating 130 tons daily. A new a114steel change house, capable of accommodating 200 men, is also under construction at the mine. It will be fireproof, and will be steam heated for winter weather. Mining is in progress between the 3,000 and 2,650 levels, while a development program is being carried out between the 3,000 and 3,500 levels. The Erin Go Bragh mine near James4 town, California, formerly operated by the California Standard Gold Mines Corporation, and more recently by the Delgold Cor4 poration. is now under lease to Stephen Rowe, Jr., the original lease-holder and first superintendent under California Standard. He is employing a small crew in retimbering the old workings. New plates and a concentrator have been installed at the Jumper and Golden Rul. mines north of Jamestown, California. The mines are operated by the Lobica.a Com. pany, Box 812, Sacramento, California, and work at the property is directed by Frank Moyle and Charles Smith. Two dredging projects are being worked by Lar.en and Harm. Brother., Route 4, Box 2220, Sacramento, California. Work at the Scandia mine on Horse Creek began in December, 1939, while operations at the Moccasin mine on the Klamath River above the confluence of Horse Creek began in February, 1940. Equipment at the, Scan 4 dia includes a 21,4 4yard Northwest dra~ line and a 40 by 48-foot Bodinson floating washing plant. An average of 4,000 yardJ per day is handled at the Scandia opera~ tion. At the Moccasin mine, about two miles of ground on both sides of the Kia· math River are available and it is expected that 2lh years will be required to work the material. Moccasin equipment includes a Bucyrus-Monigha.n dragline with a 4~cubic yard bucket, and a Bodinson float· Page 18 THE MINING JOURNAL for AUGUST 15, 1910
ing dredge, capable of handling 400 yards per hour. Emmett Miles is superintend~ ent of the Scandia, and work at the Moccasin is directed by R. H. Wallace, superintendent. The three draglines and two washing plants of the Panob Gold Dredging Company, operating near Lincoln, California, &r.e handling more than 5,000 cubic yards of material daily, working two shifts with a total of 15 men employed. Walter E. Pantie, Box 307, Auburn, California, is co-owner and superintendent of the company. His associate is C. L. O'Brien. A portion of the new mill under construction at the Sulphide Queen mine, Mountain Pass, via Nipton, California, was destroyed by fire recently, causing approximately $5,'000 damage. Repairs are to be made at once. A crew of 20 men is employed at the mine and mill. Harry Lee Martin, 117 West Ninth Street, Los Angeles, is purchasing agent for the mine. Work at the property is directed by Fred B. Piehl. Active operations began about August 1 at the French Bar placer mine on the east branch of the North Fork of Feather River, two miles above Belden, California. Preparations for working the property were begun May 16 under the direction of C. A. Cooley, Belden, and a gOO-foot flume has been built, which will make it possible to work about 1,000 feet of the present river bed. Equipment includes a la-ton powel derrick with 60-foot mast and boom, 16- inch gravel flume with three-inch block riffles, a la-inch centrifugal pump, and another small pump. At present 10 men are employed. The project is backed by a group of Tacoma, Washington, business men. The Davenport Mining and Milling Company. Auburn, California, is making arrangements to extend one of the tunnels on the property for an additional 100 feet. Upon completion of this work, the ~ompany will decide as to a further program of development. B. N. Rosenbaum, 665 Fifth Avenue, New York City, president., will be at the Freeman Hotel, Auburn, 011 July 29 and 30, to direct arrangements for the work. Wilson J. Parks, Happy Camp, California, has secured an option on a large chrome deposit near Slate and Camp CreekR in the Orleans district, and development is expected to start in the near futurE". Parks has also acquired large chrome properties in the Moffit Creek district in Scotts Valley, and he is interested in asbestos and mineral deposits in the vicinity of Happy Camp. He is president of the Curley Jack Mininr Corporation, which operates the Davis hydraulic mine one mile west of Happy Camp. Parks' headquarters are at 468 Colman Building, Seattle, Washington. The B·H Company, headed by T. M. Ger· etty and associates of Jacksonville, Oregon, has secured a lease and bond on several hundred acres of gravel lying along Indian Creek eight miles above Happ~' Camp, California. Work began July 15 with two crews sinking test pits, and all gravel removed is being run through a test plant which is a replica of the washing plant to be used on their dredge. The company, which is at present operating a dragline dredge on Forrest Creek neal Jacksonville, Oregon, has six months in which to complete testing on the California ground. Lands included in the lease are the Sedros, Huey, Wadell, Bryan, Hockaday, and Blockwell. Gravity concentration equipment at the Carson Hill Gold Mining Corporation, Me· lones, California, has been converted to flotation in an effort to reduce tailings losses. The change over was handled by the Western-Knapp Engineering Company of San Francisco. Flotation cells were installed to replace table concentration, jigd were put in for the recovery of free gold, and a concentrate regrind mill was added. Sixteen hundred feet of extra pipe line was instalJed from the concentrator to the cyanide plant, together with the necessary additional pumping equipment. John A. Burgess is general manager at Melones. Three hundred and forty feet of development work are being done at the Silver Top mine in the Fingerboard area 25 miles southwest of Quincy, California, under the direction of J. Buren Evans. The ledge is approximately 20 feet wide. A small assay office has been installed at the mine. Mining operations have been started on the Birchim-Shively group of tungsten claims west of Bishop, California, by the Western Tungsten Corporation, Ralph P.
