A group of 6 unpatented Au-W-Mo claims located in sec. 13, T7S, R14E, about 1¾ miles S of Antelope Peak, 4 miles S of E from Barkerville, 16 road miles SW of Winkleman, on private land. Owned by C. Upshaw.
Mineralization is a vein deposit hosted in granite. 2 narrow quartz veins carry W and Au values. Prevailing rock is porphyrytic granite cut by numerous stringers of quartz, which, in places, contain a little gold & tungsten. A quartz vein strikes N70E and dips steeply South. It is a few inches thick (short distance East of Upshaw's Camp). About ½ mile farther NE, a fissure zone of irregularly Eastward-trending & steep Southward dip is traceable for some 2,000 feet. It contains lenticular bodies of coarsely-crystalline, cellular, dull-white quartz. This vein is 6 to 12 inches (15 to 30 cm) wide with tungsten mineralization. Associated rock unit is the Ruin (Oracle) Granite.
Workings include a shallow pit; 70 foot deep inclined shaft with 50 feet of drifts.
