The Black Rock Basin (BRB) Project claim group is currently comprised of 320 acres on BLM ground in the southern part of the Vulture Mining District, Maricopa County, Arizona in the northeastern Belmont Mountains. The property is located along a twelve mile northwest mineralized trend where several gold and copper mines previously operated.

Bulk sampling during Bonanza's reconnaissance reveals promising higher level gold values over six large target zones. Approximately 400 soil samples were taken on a surveyed grid. These samples were sent to Chemex Labs in Reno, Nevada and analyzed for 32 elements including gold, silver, copper, lead & zinc. The results obtained from this work indicate a minimum of six gold anomalies within the claim boundaries. Over ten bulk samples returned gold values in excess of 3400 ppb (0.10+ oz/ton), including 2% copper, 20% lead, 15% zinc and up to 7 ounces of silver per ton.

Property within the BRB Project experienced minor prospecting during the early 1900's through numerous small prospect pits, shallow shafts, adits, and small tunnels. There is no formal record of production on the BRB property. The property is located approximately 80 miles west of Phoenix and 25 miles southwest of Wickenburg, Arizona, and is accessible year round. The BRB Project is situated within the lower hills and flats of the northern Belmont Mountain Range with elevations from 1900 feet to 2500 feet.
