The Puff occurrence is located near a logging road junction, west of a north-flowing tributary of the Adam River and approximately 2.6 kilometres southeast of Rooney Lake.
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, quartz veins in fractured and brecciated basaltic rock and a nearby felsite dike host chalcopyrite mineralization. Other highly sheared and locally veined zones of magnetite-chalcopyrite bearing epidosite are also reported.
In 2002, sampling yielded up to 4.5 per cent copper, 23.9 grams per tonne silver, 0.107 grams per tonne gold and 0.118 gram per tonne palladium from a 6 centimetre wide mineralized quartz vein; while a sample of the mineralized felsic dike yielded 2.25 per cent copper and 12.3 grams per tonne silver. A chip sample across the mineralized shear zone yielded 0.95 per cent copper and 4.62 grams per tonne silver over 2.2 metres (Assessment Report 27070).
In 2006, sampling yielded up to 4.65 per cent copper and 29.7 grams per tonne silver (sample PU-2; Assessment Report 28328). In 2009, a sample (109a1) taken from near the shear assayed 52.6 grams per tonne silver and greater than 1.0 per cent copper (Assessment Report 31039). In 2010, a chip sample assayed 7.1 per cent copper, 46.7 grams per tonne silver and 0.06 gram per tonne gold (Assessment Report 31856).
In 2018, a two rock samples (R12 and R25) from the Puff occurrence assayed 5.29 and 3.54 per cent copper with 34.7 and 20.8 grams per tonne silver, respectively, while a 1.0 metre chip sample (R11) assayed 0.652 per cent copper (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 claims of the Kringle property. 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.
