MLA 62-83 - Mineral Investigation Of The Moses (No. 5203) And Dennison Peak (No. 5202) Rare II Areas, Tulare County, California ? Summary

U.S. Bureau of Mines personnel examined mines, prospects, and mineralized areas to determine the mineral resources and potential of the Moses and Dennison Peak RARE II areas in Tulare County, California. These areas, along the west slope of the Sierra Nevada, are underlain by grarnitic rocks of the Sierra Nevada batholith and contain numerous metasedimentary roof pendants. Silver, copper, and zinc occur in contact-metasomatic deposits within the metasedimentary rocks. In the Moses area, the Powell Mine (fig. 1) contains an estimated 90,000 tons (82,000 t) of subeconomic silver, zinc, and copper resources. The King Solomon Prospect has 3,000 tons (2,700 t) of silicified phyllite containing zinc. On the Helen-Joyce Prospect, 44,000 tons (40,000 t) of gossan occur above a poorly exposed silver-zinc rich zone. Potential exists for additional mineral resources and occurrences at each of these properties.
