...studied outdated manuals, and trained with obsolete weapons. For at least a year I was assigned to a detail assembling wall lockers. Upon completion of my six-year obligation, I felt I would have been as well prepared to defend my country not having attended a single weekday drill...
...Congress and the AEC approve, scientists will drill a 20-in. shaft 1,200 ft. down into the ore deposit. They will then lower a 20-kiloton device to the bottom, plug the shaft, and set off a nuclear blast. From experience with previous tests, the AEC knows that the explosion will create tremendous pressures that will literally push the rock away from the blast center, fracturing it in all directions. The result will be a cavity about 200 ft. in diameter; the surface of the earth will quake, but the AEC does not expect any radioactive debris...
After about eight months-enough time for radioactivity to decrease to safe levels-mining engineers will drill three holes from the surface to the top of the "chimney" of fractured rock. Through these holes, sulfuric acid will be poured into the chimney, where it will dissolve copper out of the rock. The solution, containing copper sulfate, will then drain into holes drilled at the bottom of the chimney and be pumped up through a shaft to a precipitation plant at the surface. There the solution will be processed to extract metallic copper, and the recovered sulfuric acid recycled for another...
