SHIRLEY’S PROSPECT Platinum Gold Placer

123 Acres, Legacy claim 413468. Over 1000m per side river frontage on the Tulameen River. Located 10km W of Princeton, equidistant to Coalmont. Minfile 092H235. Most recorded production and exploration has occurred along two stretches. The upper stretch begins about 2 kilometres west of Tulameen and continues up the river for 12km to the mouth of Champion Creek. The lower stretch begins at Coalmont, just above the mouth of Granite Creek, and continues southeast for 19km to Princeton. See Tulameen River Placer (092HNE199) for a detailed review of the upper section. Metals found along the Tulameen River tend to occur in old sinuous channels buried deep below glacial gravels, which contain only spotty values. Gold occurs in rough, angular or slightly flattened and rarely well-flattened nuggets. Some of the nuggets contain abundant white quartz. Platinum forms small rounded grains of uniform size. They are smaller than the gold nuggets and are commonly pitted. Larger platinum nuggets often have a coating or included crystals of cumulate chromite, sometimes with intergrown magnetite and inclusions of olivine. The gravels worked along the river also yielded black sands containing fine platinum, in addition to gold. The ratio of gold to platinum recovered in this part of the river is about 4:1, but decreases upstream. Black sands produced by a dragline 4km above Princeton assayed 251 grams gold per tonne and 40.1 grams platinum per tonne. Farther upstream, about 3 km below Coalmont, a sample of panned black sand assayed 27 grams gold per tonne and 21 grams platinum per tonne. A series of shafts and pits at this location below Coalmont encountered gravels averaging 1.1 grams of gold equivalent per cubic metre for combined gold and platinum. Similar workings at Petersen Flat, 5 km west of Princeton averaged 1.2 grams of gold equivalent per cubic metre for combined gold and platinum. Latitude 46º27'3" Longitude 120º34'41" $25,000
