IC 7546 Mines and Mineral Deposits (Except Fuels), Park County, Mont

This report is one of a series based upon investigations made and being made within the Missouri River Basin in Montana by engineers of the Bureau of Mines , Albany Branch , Mining Division . These investigations are made primarily to provide preliminary information to the Department of Interior agencies and to others concerned with planning the proposed Federal power development within the Missouri River Basin . The present report has been designed to permit public distribution of factual data obtained . The field investigations were made during the late fall of 1947 and the summer of 1948. Information on mineral occurrences in several areas in Sweet Grass County also are included in this report because of their close proximity to Park County . Practically all known metallic mineral deposits within Park County were investigated ; some nonmetallic mineral deposits also were investigated. The investigations of the metallic mineral deposits in Park County cannot be considered complete ; some long inactive mines and prospects on which little or no information is of record may have been missed . Many of the underground openings , especially at the long inactive properties , no longer are accessible ; consequently , much of the information regarding history their and development necessarily has been obtained from available Federal and State publications .
