The Blue Chihuahua mine is a pegmatite deposit prospected for gemstones and mineral specimens. The main workings are located approximately 800 feet north of the Riverside/San Diego County line in Riverside County. In the past, the mine has been erroneously reported as being in Chihuahua Valley, San Diego County, but is actually three miles north of the area.
The pegmatite was first located by a Mr. Staley in the late 1960's. Josie Scripps became partners with Staley and named the deposit the Blue Chihuahua. Staley and Scripps removed overburden and developed several productive work areas along a thin dike with the assistance of Bob Bartsch and Al Ordway.
