California Mining Journal, December, 1942 THREE Opening the Way for -Zine and Copper Development E Heart of California is to get zinc and copper development with a number of projects that are now under way. The most immediate is a 50-ton zine concentration plant now being installed at the location of the Highway 40 gold mine on U. S. Route 40, about % mile west of Newcastle, Placer County. Leases Two Mines G. M. Trent, 353 Linden Ave., Auburn, Cal., is responsible for the Tri-County (El Dorado, Placer and Nevada) area breaking into the base metal reduction business. He is transforming the gold plant and now has under lease two properties, approximately equal distant from the plant: the Valley View copper mine in Placer County and the Buzzard, a zinc-gold mine in El Dorado County. After several months negotiations he has succeeded in securing a lease on the Placer County property from the owner, Superior Judge J. B. Landis of Auburn Cal. Some months ago he leased the Buzzard and has been getting tests of its ore made in Salt Lake. The largest test made was on a 50-ton carload lot. Valley View, 8% Copper; 12% Zinc The Valley View mine is approximately 18 miles northwest of Auburn and 9 miles east of Lincoln. It was first worked in 1862 for gold. Between 1902 and 1913 it was held by the late L. C. Trent, father of the present lease holder, and W. B. Hellings. They shipped 7 cars of ore to the Mountain Copper Co., which returned 8% copper, 12% zinc with good gold and silver values. During 1916 to 1918 a total of 21 carloads of ore were shipped. These shipments ran well in copper but so high in zinc that the necessary smelter penalty for zinc took the profit out of the venture. With present metallurgical processes, however, the zinc can be saved and is a valuable asset to the ore. An Extensive Deposit At present Trent reports that not much is known of underground conditions as the property has not been worked for 24 years. However, on the surface the gossan outcrop is very extensive, in one place being 200 feet wide and 700 feet long. Smelter returns on Valley View ore show that it makes a high grade concentrate, low in iron and indicating that the zine is a true sphalerite and not marmetite (a sulphite of zinc, high in iron content). The Placer County ore, these tests show, easily makes the necessary 45% concentrate, and it has been determined that selective flotation will do the job. In the Supervisors Survey now being made for strategic minerals a number of zinc, copper, and lead properties have been uncovered. In addition to the Buzzard and Valley View, Trent has reports on five other properties. He now announces that it is his intention to aid in the development of these properties by taking custom work and thus bringing them to a stage where large operators will be interested. One property, he points out, runs 15% copper, $12 in gold and some silver. The Trent plant will consist of a 54 Marcy mill, two banks of flotation cells and a conTwo Stock Piles for Manganese at Tracy TRACY, (Stanislaus Co.), Nov. 10.—O. E. Chaney and associates are shipping manganese ore from the Schmidt property, following several months of vigorous development work. The product is in the form of pyrolusite and is especially in demand for the manufacture of dry batteries. Considerable ore has been stockpiled and the outlook is promising for a long productive period. A manganese buying station has been established in Tracy by a Baltimore, Md., manufacturer of dry batteries. Tracy also has a Metals Reserve stockpile for chrome, manganese and quicksilver. Chaney formerly was manager of gold properties on the Mother Lode, near Amador City and in Nevada. centrator. Trent states that he long has had a conviction that such a plant will be a considerable factor in developing the base metal resources of the Tri-County area. Picks Lincoln For Fuming Plant Trent is also interested in seeing that the area gets a zinc fuming plant. He says the town of Lincoln is strategically located for such a plant, due to the fact that it has excellent main-line highway and rail shipping facilities, a natural gas supply for fuel and the clay necessary in the processing of the zinc. Such a plant, Trent states, will greatly aid the development of western ores with the elimination of high freight charge to plants at Great Falls, Montana, and at Amarillo, Texas. The Lincoln plant would not only serve the prospective mines of the nearby area but would serve Amador, Calaveras, Shasta and Siskiyou copper operations now getting under way. Shasta Gets 300-Ton Plant Incidentally: Trent tells of the 300-ton zinc selective flotation plant now being installed by the Mountain Copper Co. on their Shasta County operation. They are moving equipment from their Big Canyon gold mine in El Dorado County. They will use selective flotation. General Manager F. W.
