Standard Hill Mines is an independent claim holder in Kern County, California.
Standard Hill Mines owns a group of five patented and 14 unpatented mining claims, approximately 300 + acres, about 3 miles south of Mojave, 65 miles north of Los Angeles, California.
From its discovery in 1894 until underground mining finished in 1956, it is estimated that Standard Hill Mines produced approximately 150,000 oz gold and approximately 500,000 oz silver, from over 15,000 ft of horizontal drifts and stopes to a depth of 900ft down the dip of the mineralization. During open pit mining by Shell Oil Co. (Shell)/Billiton Minerals (Billiton) from 1987 to 1990 it is estimated an additional 77,500 oz of gold and 258,000 oz of silver were produced. Standard Hill Mines is a well documented, historical producer. It lies within the Mojave Mining District that has been active for almost 120 years. The property has not had any exploration activity performed on it since mining was completed in 1990 by Shell/Billiton. Historical records, as well as the exploration database created by Shell/Billiton during its exploration in the 1980s, indicate that the property still has potential for more economic mineralization. The property is currently leased to Granite Construction of California for the extraction of non-mineralized aggregate and rock.
