MLA 22-81 - Mineral Resources Of The Buttermilk Rare II Area (No. 5-038), Inyo County, California - Summary

The U.S. Bureau of Mines made an economic appraisal of the Buttermilk study area, Inyo County, California in October 1980. Results of surveys indicate no potential for metallic, non-metallic, or energy resources in the area. However, glacial till covering most of the area prevented bedrock examinations by the appraisal teams or earlier prospectors. No mining claims are known to be in the area. INTRODUCTION Present Studies The U.S. Bureau of Mines, Western Field Operations Center, searched county mining claim records and other data available concerning mineral deposits, claims, leases, production, and mining activity in the area. The Bureau conducted field work in October 1980 searching for prospects and claim locations.
