Show MINES AT FRISCO OPENING NEW LEADS Development in the Horn Silver mines of the Tintic Lead company at Frisco, Utah, is being centered en opening up the continuation of the large replacement ore body being sloped in 926, fifty feet above the 9 00 level. In the meantime, shipments ship-ments of ore at the rate of eleven carloads weekly are being maintain ed. . At the adjoining Frisco Lulu mine of the American Smelting and Refining Re-fining company, the collar of the shaft has been done, an electrical hoist set up and a compressor and drill-sharpener installed. A water tank for storage purposes has been built and a pipeline laid. Water will be hauled to the mine in tank cars by the railroad and drained into the tank. Some of the men are being boarded at the Horn Silver mine. Others are living in Milford and driving to work. When the surface work at the Frisco Lulu is completed, crosscut-ting crosscut-ting of the limestone beds productive produc-tive in the adjoining Tintic Lead property will be undertaken, it is said on the 200 and the 400 foot levels. Ore Reserves Added to The most important development of recent weeks at the Horn Silver is the opening up of a sulphides, ore body in 923, 50 feet below the bottom bot-tom of 926 and 50 feet to the northeast, north-east, indicating the downward continuation con-tinuation to the northeast of the big silver-lead-zinc ore body, in 826. This deposit was missed on the 900 level in the drift by but two feet. When Manager Karl G. Link decided to pub up a raise to catch the continuation con-tinuation of 926, the strike was made. Since striking the ore, the drift has been in ore for thirty feet. In a number of places, redoxide of zinc, identified as mannheimite by R. T. Walker, geologist for the United States Smelting, Refining and Mining company on a recent visit to the property, has been opened up in large quantities. This material, running run-ning from 10 to 25 per cent zinc, is being piled on the dump for future shipment when the demand for zinc oxide will permit its marketing at a profit. Other Leads Followed. This mineral which in other places on the 900 has been a marker leading lead-ing to the large sulphide deposits, is being followed in a number of headings. head-ings. In 928, 200 feet northwest of 926, a large body of red oxide of zinc has been followed for 4 0 feet above the level. It is in this area, the management is expecting the next imprtant development. No. 929, 150 feet north of 926, the formation is softening and iron and chert coming com-ing into the face. The orebody in 926 is proving to be a great, irregular orebody making mak-ing out into the limestone where-ever where-ever the formation has favored replacement. re-placement. The stopping area on the main floor about 50 feet above the 900 level contains about 3600 square feet. The ore is of varying widths, fin one (place the stoping thickness extends below the main floor and clear up to the 800 level. Grade of the ore has averaged, according ac-cording to Manager Link, close to 10 oz. of silver to the ton, 10 per cent lead, and 10 per cent zinc. The mineralization in 926 is evidently evi-dently associated with two main fissures, fis-sures, a northwest-southeast and a northeast-southwest. To the east and north of 920, Assure As-sure ore has been continuous from above the 1000 to the 720. Width has ranged from 3 to 10 feet. Shipments are being made from the 200 the 300, the 500, 700, 800 and 900. Low grade gold ore is being be-ing produced from the 200. On the 700, in the Central area, a copper ore, carrying silver and lead, is be-jing be-jing mined. Mineral Survey. |
