CHEYENNE, Wyo.—George Bee is prospecting for gold in folds of feldspar, granodiorite, and quartz exhumed from faults in the earth’s crust, hundreds of feet below a ridge-rimmed prairie vale on the eastern flanks of the Laramie Range.
He doesn’t need a pickaxe to muscle mineral from stone, or a stream-side sluice to sift river slag to find what he seeks. He doesn’t even need to be at the mine, a nondescript slit-trench gash amid waving buffalograss and sage-crested arroyos, to see its bonanza.
