This prospect is in the Karta River Wilderness Area, which is closed to exploration and mining.
Location: The Buckhorn prospect is at an elevation of about 3,000 feet about 0.3 mile north of Granite Mountain and 0.5 mile south of the center of section 17, T. 73 S., R. 84 E. The location is accurate.
Geology: The rocks in the vicinity of the Buckhorn prospect are part of a large granodiorite-quartz diorite stock (Sainsbury, 1961; Eberlein and others, 1983; Brew, 1996). Early workers considered it to be Mesozoic or Cretaceous, but recent radiometric dating indicates that it is Devonian (S.M. Karl, oral communication, 2003). Wright and Wright (1908) described the Buckhorn prospect as 9 claims explored by open cuts and several tunnels. A quartz vein about 15 inches wide that strikes N5W and dips 45NE can be traced for several miles. The vein has free gold and sulfides. The sulfides are unspecified but the vein reportedly is similar to quartz veins at the Flagstaff Mine (CR043) that contain chalcopyrite, galena, and pyrite. Maas and others (1991) found a trench and caved adit. A 1-foot sample across a quartz vein in the trench had negligible metal values. A sample of quartz with pyrite from the dump of the adit contained 2.2 parts per million (ppm) gold and 15.7 ppm silver.
Workings: The workings consist of a trench and a caved adit.
Age: Unknown, other than that the vein is in Devonian granitic rocks.
Commodities (Major) - Ag, Cu, Pb
Development Status: None
