Sep 11, 2015 (A Wilson) - Although worked extensively for mica during recent years, this property was originally opened for phosphate, in 1871, by an English company, several hundred tons of mineral being raised. The vein—composed of calcite, mica and apatite was reported to have measured over 25 feet in width. In 1892, the mine was acquired by the Lake Girard Mica System, who worked for both mica and phosphate, and subsequent operators include the Mica Manufacturing Company, of London, and Messrs. Sewell and Smith.
