Dawson (1894) reported that 'stibnite occurs near Watkinson's, about 23 miles above Lytton, on the Fraser'. The vein is reported to be about 35 centimetres wide, with quartz and calcite. The stibnite yielded traces of gold and 74.9 grams per tonne silver. The locality is about 800 metres south of the intersection of Highway 12 and Cinquefoil Creek. Rocks in the vicinity are tightly folded sediments of the Jurassic-Cretaceous Relay Mountain Group cut by rusty granitic dikes. Abundant quartz-calcite veinlets were observed; pyrite occurs irregularly in the dikes. Tetrahedrite is reported from near this same locality (Geological Survey of Canada Memoir 262, page 96).
