Mine the Rock. Fortunately, Dr. Brown says, ore deposits get bigger as they fall in grade. Clay, which is everywhere, is a low-grade aluminum ore, and sulphur can be extracted from plentiful calcium sulphate (gypsum). Even ordinary rocks can be processed for their minerals. One hundred tons of an average igneous rock, e.g., granite, contain eight tons of aluminum, five tons of iron, 1,200 lbs. of titanium, 180 lbs. of manganese, 70 lbs. of chromium, etc. Dr. Brown believes that the time may come when rock is refined into 20 or 30 products. Rock reserves will last indefinitely...
...struggling to stay alive. The troubles were symptomatic of the change coming over the U.S. uranium industry. Instead of a headlong scramble for a quick million, uranium has grown into a tough, mature business where the survivors are those big enough to find and mine enough high-cost ore to come out ahead...
Last week, for the first time, the Atomic Energy Commission's Director of Raw Materials Jesse Johnson revealed exactly how big a business uranium has become. In testimony before a congressional subcommittee, Johnson reported that ore shipments from the four-state Colorado Plateau area (90% of U.S. total output) will hit 1.5 million tons worth $46.5 million in fiscal 1956. He predicted that within two years Plateau production will increase to 2,500,000 tons annually. Said Johnson: "During the past two months, the AEC has received and is actively considering more proposals for processing mills than...
Mining and exploration costs have gone up 51.6% between 1951 and 1955. At current prices, even big outfits run into serious cost problems. Estimates are that a 2,000-ton ore deposit becomes unprofitable at depths of 90 ft., that even a 10,000-ton deposit cannot be mined successfully below 240 ft. By 1960, say miners, costs will have climbed until exploration alone will cost $13.92 per ton. The Four Corners Uranium Co., which grossed $1,160,000 in 1955, spent $716,000 to mine $653,000 worth of ore, would have been deep...
...Toronto Street. While Canada's ore-rich economy has surged irrepressibly ahead since World War II, the boom might have bypassed Bay Street if President Trebilcock had never ventured, via the World, into a financial career. After working up to business editor, he quit to study mining law, later hung his shingle over a tent at Red Lake camp in Ontario's 1925 gold rush. On his return to Toronto, Trebilcock was appointed counsel to the old Standard Stock and Mining Exchange, Canada's key mining market; in 1934 he worked out a merger with its rival...
