Capsule Geology

The Ned property is underlain by Upper Triassic Nicola Group volcanics overlain by the Eocene Kamloops Group. Nicola rocks are predominantly green-grey, massive and porphyritic andesite with minor tuffs. The Nicola rocks usually exhibit widespread chlorite and epidote alteration and locally calcite. Kamloops Group volcanics are typically porphyritic basalts and weathered, pink-brown rhyolites.

Mineralization found in outcrop consists of malachite and azurite in Nicola andesites in old pits/trenches. Just north of Ned Roberts Lake, an area of about 500 by 500 metres exhibits extensive carbonate and chalcedonic alteration, ranging up to intense argillic alteration with almost complete silicification of the hostrock (Silica Hill zone). This zone has been recognized to have potential for precious metal epithermal mineralization. Drilling on the Silica Hill zone in 1994 intersected 1.5 metres of silicified, pyritic brecciated volcanics grading 10.7 grams per tonne gold (hole 94-3). About 183 metres south of the Silica Hill zone, drillhole 94-1 intersected a gold-bearing zone in a northwest trending fault. The Ned Gold zone is at depth and is a 20.7 metre section of brecciated, graphitic mudstone and tuffaceous sandstone. One intersection yielded 64 grams per tonne gold over 2.44 metres; a second intersection 7.6 metres further down the hole intersected 13.4 grams per tonne gold over 1.52 metres. At the bottom of this drillhole (94-1) from 122 to 136 metres, a serpentinized ultramafic was intersected and yielded up to 0.16 per cent nickel, 600 ppm chromium and 18 per cent magnesium (Assessment Report 24195).

The Kon and Win claims were staked in 1969 near the southwest edge of the Iron Mask batholith and around Ned Roberts Lake. In 1969-70, Concorde Explorations Ltd. conducted line cutting, geological mapping, soil sampling (619) and a ground magnetometer survey. In 1972, Concorde Explorations completed 15 kilometres of induced polarization survey. In 1975-76, Afton Mines Ltd. conducted geological mapping, soil sampling (276) and 9 kilometres of VLF-EM survey on the Hughes claims which now cover the Ned Roberts Lake area. In 1989-90, an airphoto interpretation report with limited rock and soil sampling was completed on behalf of Rhino Resources Inc. In 1993-95, Rhino Resources continued work on the Ned claim by conducting airphoto and geophysical interpretation, geological mapping and diamond drilling 11 holes totalling 1803 metres.
