San Joaquin County

  • San Joaquin County Mines and Mineral Resources (circa 1913-1914) – Excerpts from Report XIV of the State Mineralogist - Mines and Mineral Resources of Portions of California, Chapters of State Mineralogist's Report - Biennial Period 1913-1914, Part IV. "The Counties of Fresno, Kern, Kings, Madera, Mariposa, Merced, San Joaquin, Stanislaus," by F. L. Lowell, Field Assistant (field work in August, 1914), San Francisco, California, July, 1915, California State Mining Bureau, San Francisco, California, 1916, pp. 173-370.

    "San Joaquin County, of which Stockton is the county seat, has an area of 1370 square miles or approximately 926,720 acres. Of this acreage 763,048 acres are in farm lands. The population of the county was 50,731 in 1910. The county may be classed as agricultural and very little mineral is found in commercial quantities to pay for working.

    "The principal output under a mineral head is natural gas. There is also some manganese, clay and indications of coal in the Corral Hollow district in the southern end of the county. Water is abundant and is obtained from wells and irrigation ditches. The county is bounded on the north by Sacramento County, on the northeast by Amador and Calaveras counties, on the east and southeast by Stanislaus County, in the southwest by Alameda County and on the west by Contra Costa County."

  • San Joaquin County Mineral Industry (circa 1919) – Excerpt from California Mineral Production for 1919, Bulletin No. 88, by Walter W. Bradley, California State Mining Bureau, 1920.

    Area: 1,448 square miles.
    Population: 79,905 (1920 census)
    Location: Central portion of state.

    "San Joaquin County reported a mineral production for the year 1919 having a total value of $449,000, as compared with the 1918 output, worth $601,973, the decrease being due mainly to brick and manganese. Comparatively few mineral substances are found here, the chief ones being brick, clay, manganese, natural gas, glass-sand, and miscellaneous stone. Gold, platinum, and silver are obtained by dredging in the Mokelumne River, which forms the boundary between this county and Amador on the northeast.

    "In twenty-eighth place, commercial production for 1919 was as follows:

San Joaquin County – List of Stone Quarries, Etc.*

(* Please note this list does not include sand or gravel quarries.)

  • Carnegie (south of), San Joaquin County, California – the California Lime and Cement Company’s Quarry and Lime Kilns (Limestone) (From The Structural and Industrial Materials of California, Bulletin No. 38, California, State Mining Bureau, San Francisco, California, 1906.)

    "California Lime and Cement Company's Quarry, located about three fourths of a mile south of Carnegie. The company's offices are at 328 Montgomery street, San Francisco. The quarry was opened in 1900 and the lime was originally burned in an open kiln at the quarry, but at present the rock is hauled to the railroad siding at Carnegie and burned in a continuous oil-burning kiln, with a capacity of 200 barrels per day. The lime is only burned as it is needed for building purposes at Tesla and Carnegie. Some lime rock is shipped to the glass works at Stockton. The rock occurs in a series of aragonite veins, varying in width from 3 inches to 3 feet and dipping to the northeast at an angle of about 65 degrees. It is overlaid with crushed shales stained with iron. The quarry was opened for about 75 yards, with a face averaging about 40 feet high. Four prospect tunnels further developed the deposit and exposed considerable serpentine inclusions, which cause much waste in quarrying."
