The Cruller showing is located west of the Adam River, approximately 11.5 kilometres east-southeast of the community of Sayward.
The area to the west of the Adam River is underlain mainly by the upper part of the Triassic Karmutsen Formation, comprising mainly thick massive flows with local intercalations of amygdaloidal basalt and pods of autoclastic breccias, pillowed and massive flows with thin intercalations of volcaniclastic and limy sandstones, all cut by thin dolerite/gabbro sills.
Locally, distal skarn contact mineralization occurs near a porphyritic monzodiorite dike. The dike appears to strike 150 degrees. Mineralization consists of pyrite, chalcopyrite and malachite.
In 2006, sampling yielded up to 2.71 per cent copper, 5.6 grams per tonne silver and 0.35 grams per tonne gold (Assessment Report 28747). In 2010, sampling of the zone returned up to 2.83 per cent copper and 6 grams per tonne silver (Assessment Report 31856).
The Eclair occurrence is located a few hundred metres southwest of the Cruller showing. Locally, amygdular (feldspar) phyric basalt host quartz veins with chalcopyrite and bornite.
In 2011, sampling yielded up to 6.09 per cent copper (Assessment Report 32553).
In 2018, seven rock and chip samples (R6 through R8, R26, R27 and R29) from the Éclair occurrence area assayed from 1.88 to 14.95 per cent copper, 2.0 to 27.4 grams per tonne silver and 0.04 to 1.24 grams per tonne gold, while another sample (R28), taken several hundred metres to the east, yielded 2.54 per cent copper and 7.7 grams per tonne silver (Assessment Report 38134; MacIntyre, D. (2018-07-18): Technical Report - Red Metal Ridge Mineral Property).
Work History
During 2002 through 2013, M. Schau completed programs of prospecting, geological mapping and rock sampling on the area as the Puff and Kringle claims. In 2018, Crest Resources Inc. completed a program of prospecting, geochemical (rock and soil) sampling, trenching and a 24.0 line-kilometre ground electromagnetic survey on the area as the Red Metal Ridge property.
