Show MINING EXPERTS SEE NEED OF MORE PROPERTIES Domestic development of tungsten tung-sten and copper deposits must begin soon if United States is to have a plentiful supply of these two vital minerals, two prominent promin-ent mining men said in Salt Lake City Monday. Van Rensselaer Langingh of New York City, vice president of Molybdenum corporation of America, reported that his company com-pany is beginning to mine and, mill tungsten near Milford. Most of the known domestic tungsten deposits are in Nevada and California Cali-fornia and supply 40 per cent of the ore needed annually in this country. Much that is used is imported from South America and China. A consulting mining engineer, C. Q. Schlereth of Denver, said it is his opinion that more copper cop-per mines must be developed in this country or the amount of ore mined will begin to decline de-cline within nine years. "One of the notable exceptions is the Utah Copper company mine at Bingham, which apparently has ore for many, many more years", Mr. Schlereth said. -s |
