The Laguna Mountains are in east-central San Diego County east of Cuyamaca Rancho State Park and 55 miles east of San Diego. A considerable number of claims have been located here, but the principal gold source has been the Noble mine, which yielded more than $60,000 between 1888 and 1914. The district was prospected during the 1920s and 1930s. The ore deposits consist of narrow north-striking gold-quartz veins in shear zones in mica schist, gneiss, and quartz diorite. This district is at the southeast end of the same belt that includes the Julian-Banner and Cuyamaca districts.
