Description: From abstract: Pitchblende is known to occur in the Jo Reynolds deposit, which was primarily a lead-zinc-silver ore body. The reported production in 1919 of 8 tons of high-grade uranium ore, presumably from the lowest workings of the mine, is still unconfirmed but has a fair degree of credibility.
