A placer gold deposit area in parts of T7 & 8S, R8, 9 & 10W, South & central Muggins Mountains. The major placers occur in Burro Canyon. Minor ones are found in smaller canyons in the vicinity of a prominent mountain that is variously known as Klotho, Coronation, or Muggins Peak, and also at the southern base of Long Mountain.
Southward-dipping lava flows, intercalated with thick beds of conglomerate, form a rugged terrain. This conglomerate, which consists mainly of coarse, sub-angular pebbles of gneiss and granite, rather firmly cemented in a sandy to clayey matrix, forms the bedrock of the placers. The gold-bearing gravels occur principally as ancient bars several feet above the streak channel and, to a less extent, in the present stream bed. The gold occurs as particles up to 0.15 inch in diameter, mostly concentrated at or near bedrock. It appears to have been derived by erosion of the conglomerate, in which it was probably present as low-grade placer material derived from gold-bearing quartz veins originally contained in the gneiss, schist, and granite of the range.
Workings were numerous surface workings.
