Higglns, mining engineer and general manager of the Kortuna, one of the properties recently consolidated with the Montana-Bifigham Consolidated Minim? Min-im? company, said yesterday that the pumping plant installed a week ago to furnish water fur tbt; new oil flotation mill from the Montana-Binsham drainage drain-age and transportation tunnel is now in entirely successful operation. A large sump was constructed in the draining and transportation tunnel about 3OU0 feet in from its portal where connection was made with the lower workings of the OtJiiKor mine. The pipe line was run through the Connor incline from the sump to the surface and thence to the Kortuna mill, a distance of approximately approximate-ly 3500 feet. While the pump has been working- to capacity, there is but little diminution in the sump water. The first unit of the new mill, Mr. Hig-gins Hig-gins says, Is working entirely successfully, success-fully, concentrating approximately seven tons of copper ore, averaging around 2 per cent into one, making a concentrate of from 15 to 20 per cent copper. From $1500 to $2000 worth of concentrates are now being produced dally. There are some 70,000 tons of ore on the dumps ready for concentration and an unlimited quantity of milling ore of 2 per cent copper cop-per blocked out in the mine. Work has already been 'begun on the installation of the second unit, which will be ready to operate as quickly as machinery ma-chinery can be gotten on the ground. Other units will be added as speedily as possible. Air. LI is gl na asserts that the Fortuna ore has proved more susceptible to oil flotation than any of the ores in the Bingham district, and that the saving is large. He predicts record-breaking shipments ship-ments of concentrates this month. |
