Show EVADA DOUGLAS IS OPffliH ODES Casting Copper Section Showing Show-ing Large Tonnage Twelve Per Cent Material. Superintendent Archie Orem of the Nevada Ne-vada Douglas Copper company has wired the Salt Lake offices to the cfToct that on the 100 and 200 levels of the Casting Copper section of tho property he has full faces of 12 per cent, copper oro. On the 100-foot level, tho crosscut Is now In fifty-live feet all the way In ore, while tho crosscut, on the 200-foot. level Is sixty feet In, all In ore, while at noithor placo have any walls boon encountered to date. This Is the most gratifying news that the Nevada Douglas company has r- nnU.vrl IV,,. o nnnvWl fn 111 norlnrl nu II tends to establish the truth of the assertion asser-tion made by the management some months ago that the Casting Copper section would prove to be as good as. If not belter than, the Ludwlg section. This Casting Copper development la bringing substantial tonnages to sight and Increasing In-creasing the company's production ability abil-ity In a very gratifying manner. The plan of the Nevada Douglas company com-pany to equip tho property with a leaching leach-ing plant will bring into available form a very large tonnage of copper oro now developed, but which can bo better handled han-dled In a leaching plant than by dirout smelting. It Is ostlmatod that there arc from 500,000 to i00,000 tons of such ore available, tho average of which Is anywhere any-where from 2 to 3J per cent coppor. Tho exhaustive sorlcs of experiments mado by leaching experts on the Nevada Douglas Doug-las ores has demonstrated that ores carrying even less than 2 per cent and over li per cent can be handled profitably, profita-bly, and tho company Intends to Install a mill consisting of five unlta each with a daily capacity of 300 tons of ore. The system to be used will be leaching leach-ing bv the agency of sulphuric acid and precipitation by electrolysis, while the arrangements for a Pacific coast market will materially reduce the company's cost of production. The Nevada Douglas management, man-agement, is rounding out the new plans In a comprehensive manner, and there- Is considerable Interest, drawn lo the company com-pany by virtue of Its new plans. |
