' Silver ore carrying from 20 10 40 ounces per ton Is being shipped to ! smelter from properties operated by the I Candelarla' Mines company, at the old camp of Candelaria, near the boundary between Esmeralda and Mineral counties, says the Mining and Scientific Press. The Argentum and Mt. Diablo mines were worked In the late '70s, and were among the largest of Nevada silver producers pro-ducers in that period. The district was then known as the Columbus. The adjoining ad-joining Lucky Hill property, also owned by the Candelaria Mines company, Is being worked through a tunnel and shaft. Stopes on the 100 and 200-foot levels are breaking from eight to eleven feet of shipping ore, and a large tonnage of mill- I ing ore has been exposed. The ' first named properties have a large quantity -of impounded tailing from the old mills that is said to be valuable. Four carloads car-loads of smelting ore was shipped during dur-ing the last week of January. Ore is shipped at a rate sufficient only to pay for development and leave a moderate surplus. A. J. Jarmuth is manager. New Mill at Unionville. A flotation mill has been completed at Unionville, In southern Humboldt county, to treat ore from the once famous fa-mous Arizona silver mine, owned by the Sunset Mining & Development company. Connection with the old mine workings has been made by a 390-foot tunnel, giving giv-ing access to the ore channel below any , point reached before. The ore, a straight silver sulphide, is found in a wide bedded bed-ded zone, lying nearly horizonta1 and worked in earlier operations to a depth 1 of only 250 feet. The mine is said to have produced $5,000,000 in the '60s, the high-grade ore having been shipped to Wales by way of Sacramento. It was located In 1S02, and the richest ore was freighted to the coast before the railroad came to Nevada. E. S. Van Dyke, vice president, is now at the mine. He says that- a relatively small part of the ore channel has been prospected. F. W. Lockman is superintendent. The ore has been tested for flotation, and is said to be well adapted to that process. Leasing at Goldfield. The new leasing policy of the Goldfield Development company will glve longer lease terms, with no restrictions on profits, prof-its, and ample time for the removal of ore extracted. It is expected, together with operations planned by the new company, com-pany, to result in a more energetic and more venturesome policy of mining In this area, a large part of which has not been prospected. The company will furnish fur-nish equipment, air, timber and supplies to-the lessees at about cost, and its own work is designed to produce ore for company com-pany account and to open the properties for leasing. The manager, H. G. Mc-Mahon, Mc-Mahon, reports over 100 applications for leases already in hand. It is not likely that lessees will for the present undertake under-take work on deep levels, as the product contains copper and the Consolidated' company Is opposed to resuming the operation op-eration of its flotation plant until the copper market is stabilized. In a report on the Atlanta property, the manager, A. I. D'Arcy, says that a considerable quantity of milling ore has been exposed, and the east cross-cut on the 1000-foot level, driven to cut the Atlanta vein, has lately shown several seams of good ore, assaying as high as S59 per ton in gold and copper. While the lens-shape of the deposits renders it impossible to estimate the tonnage, he believes sufficient ore wjll be available soon to warrant leasing or building a mill. |
