Capsule Geology

The California Extension occurrence is located east of the Hurley River, approximately 1.5 kilometres west of the north end of Noel Lake.

The area is underlain by greenstones and coarse clastic rocks of the Upper Triassic Cadwallader Group. To the east these are in contact with serpentinite ultramafic rocks of the Permian Bralorne-East Liza Complex.

Locally, andesites and greenstones host a 5.0 metres wide silicified and carbonitized (listwanite) shear zone that hosts gold values. The zone strikes 140 degrees and dips 50 degrees east.

It is reported that the zone grades 4.5 grams per tonne gold over 4.0 metres, with assays of up to 15.8 grams per tonne gold over 1.0 metre (Assessment Report 23773). In 1994, diamond drilling yielded up to 1.8 grams per tonne gold over 1.06 metres (Assessment Report 23773). In 2007, diamond drilling yielded values of up to 1.58 grams per tonne gold over 1.51 metres (DDH MB07-01; Assessment Report 30106).

The area has been explored in conjunction with the California (MINFILE 092JNE020) occurrence. In 1994, Levon Resources completed a program of trenching, geochemical sampling and nine diamond drill holes, totalling 620.0 metres, on the area as the BRX property. In 2004, Mill Bay Ventures, on behalf of Levon Resources, completed a program of trenching and diamond drilling, totalling 726.2 metres in nine holes, on the area. In 2007, a program of geochemical sampling and a lone drill hole, totalling 636.1 metres, were completed.
