Capsule Geology

The Dekalb 4 occurrence is located at an elevation of approximately 1780 metres on the northeast-facing slope, east of Quartzrock Creek and approximately 12.5 kilometres east of the historical community of Cassiar.

Regionally, the area is underlain by cherts, greywacke, greenstones and mafic volcanics of the Upper Paleozoic Sylvester Allochthon (Slide Mountain Complex) and serpentinite ultramafic rocks of the Permian Blue Dome fault zone (Slide Mountain Complex), which are folded and faulted and intruded by a small hornblende-feldspar porphyry stock.

Locally, a quartz pod is reported to host gold values.

In 1981, a chip sample is reported to have assayed 11.5 grams per tonne gold over 3.0 metres, later sampling in 1983 returned only trace gold values (Assessment Report 12498).

Work History

The area has been explored in conjunction with the nearby Lucky Shot (MINFILE 104P 041) occurrence and a complete exploration history can be found there.
