"Company: St. Louis Smelting and Refining Company...The fee is some five hundred acres of mining land is owned by the company, and an additional two hundred acres is held under a mining lease. Drilling had proved the ore to occur in a dolomitic horizon and to contain from 3 to 12 per cent zinc and small quantities of lead. Early in 1930, some thought was given by the officials of the company to the erection of a concentrator to mill the ore from this acreage. During the ensuing months a basic flow sheet and type of structure were tentatively approved, but no further action was taken for years because of the low prices offered for zinc concentrates"--leaf 4.
