Capsule Geology

The Late occurrence outcrops along the northeast shore of Thumb Lake, approximately 2 kilometres north-northwest of the north end of Vincent Lake and 41 kilometres north-northeast of Princeton.

This occurrence is hosted in massive red andesitic breccia, near the contact with massive green andesitic breccia and lithic tuff of the Upper Triassic Nicola Group.

Locally, chalcocite and rarer bornite occur in north-trending fracture zones, and less commonly as disseminations, over an area 240 metres long and 120 metres wide. Stringers of epidote, calcite and specular hematite are associated with the chalcocite and bornite. Malachite usually accompanies this mineralization.

Work History

In 1972 and 1973, Great Plains Development Company of Canada Ltd. completed programs of geological mapping, geochemical (silt and soil) sampling and 62.0 line-kilometres of ground electromagnetic and magnetic surveys on the area as the Buck group of claims.

In 1981, Inter-Continental Energy Corp. completed a program of geological mapping, geochemical (rock and soil) sampling and ground magnetic, electromagnetic and induced polarization surveys on the area as the Late claims. A sample (no. 1) with traces of chalcocite and malachite assayed 0.024 per cent copper, 0.2 gram per tonne silver and less than 0.001 gram per tonne gold over 1.0 metre, whereas a second grab sample (no. 2) from a pit excavated in a shear with malachite staining, approximately 150 metres northwest of the previous sample, assayed 0.0082 per cent copper, 2.4 grams per tonne silver and 0.001 gram per tonne gold (Assessment Report 10448).

During 1986 through 1991, Fairfield Minerals Ltd. completed reconnaissance programs of rock, silt and soil sampling on the area as the Vin 1-19 claims. In 1991, a chip sample (VN91-R16) from an outcrop of volcanic rock hosting an east-trending, 2- to 3.5-centimetre wide, quartz-calcite vein/shear with fine-grained pyrite masses, located approximately 1 kilometre northwest of the Late occurrence, yielded 0.690 gram per tonne gold and 3.4 grams per tonne silver over 0.2 metre; previous to this, during 1986 through 1990, an undescribed sample (Q14-R2) from the same location as the previous sample (VN91-R16) yielded 0.720 gram per tonne gold and 2.5 grams per tonne silver (Assessment Report 22259).

In 2009 and 2012, Victory Resources Corp. completed programs of photogeological structural (lineament) analysis on the area as the Toni property. In 2014, a 5.9 line-kilometre ground electromagnetic survey was completed on the area.
