Capsule Geology

The Torres occurrence is located 3 kilometres southeast of Orofino Mountain, near the summit of the old Fairview-Cawston road. Oliver lies 9 kilometres to the southeast and Keremeos lies 12.5 kilometres to the west-southwest.

The Torres occurrence is located within Middle Jurassic diorite and dioritic feldspar porphyry that has been subsequently intruded by granite and granodiorite of the Jurassic Oliver plutonic complex. To the immediate south of the occurrence lies metasediments and metavolcanics of the Carboniferous to Permian Kobau Group. Chloritic schist with intercalated limestone, greenstone and serpentinite comprise lithologies of the Kobau Group. Younger aplite and lamprophyre dikes are found crosscutting all older rock units.

The old workings were restaked on the Mars 1 claim, which is underlain by diorite. The quartz veins occupy a shear zone in diorite. The veins contain lenses and disseminations of pyrite, chalcopyrite, galena, sphalerite, arsenopyrite, tetrahedrite, gold and silver. Crossfaults have displaced some of these veins about a metre.

The Torres occurrence was first discovered in 1933 and acquired by Viking Gold Mines, Ltd. in 1934. A 10-metre inclined adit and numerous open pits explored two 0.9 to 1.2-metre wide quartz veins. A chip sample across 1.8 metres yielded 8.23 grams per tonne gold (Minister of Mines Annual Report 1933, page 167). A grab sample yielded 274 grams per tonne gold. A select grab sample from the adit yielded 30.86 grams per tonne gold and 394 grams per tonne silver (Minister of Mines Annual Report 1933, page 167).

In 1934, a 186-metre adit was driven slightly below the inclined adit. This adit intersected two veins varying from several centimetres to 1.8 metres wide. Crosscuts were made north and south of the adit. Samples generally yielded low gold values but some high-grade sections were intersected. A 7.6-centimetre vein was sampled at the face of the adit. An assay of this vein yielded 100 grams per tonne gold and 840 grams per tonne silver (Minister of Mines Annual Report 1934, page D15). In 1935, Viking Gold Mines shipped 2 tonnes of ore, yielding 187 grams of silver, likely from this property.

Topper Mining Ltd. mined 40 tonnes of ore from the Torres occurrence in 1973. Recovery included 809 grams of silver, 62 grams of gold, 80 kilograms of lead and 40 kilograms of zinc.
