The Yosie property is centred 1 kilometre north of the confluence of Mineral and Crusader creeks, 14 kilometres east of Slocan. Access from the Slocan highway is via the Crusader and Lemon creek roads.
Little is known about this property other than galena occurs on small shears in Nelson granodiorite as seen in a few open cuts and pits. Structural control of the mineralization is apparently related to faults trending northeast subparallel to Mineral Creek and VLF-EM 16 anomalies. C.C. Young worked the claims in 1978 and 1979; 4 tonnes were produced in 1985, yielding 1385 grams of silver, 2 grams of gold, 1205 kilograms of lead and 170 kilograms of zinc.
