Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Orebody): Sherman vein is a split from the Union vein which extends SW through Hidden Treasure ground to connect with Tiger-Poorman vein. The Sherman vein may also be a SE extension of the Custer Vein of the Tamarack and Custer mine.
Comment (Production): Ore tonnage and recovered metas as reported by Mitchell and Bennett (1983) from US Bureau of Mines data; grades from Day Mines, Inc. data.
Comment (Reserve-Resource): According to Shenon and others (1954) much low grade lead ore remains on the Sherman vein.
Comment (Development): Main Sherman orebody discovered in or just before 1927.
Comment (Development): 12 PATENTED CLAIMS, 1 MILLSITE
Comment (Deposit): LEARY VEIN STRIKES N 60 DEG W, DIPS 70 DEG S. IN THE TAMARACK - MARSH SUBBELT.
Comment (Workings): LENGTH OF WORKINGS A 1961 FIGURE
