Capsule Geology

The Pen 5 showing is 1.3 kilometres east-northeast of the summit of Pennask Mountain and 1.1 kilometres north-northwest of Hidden Lake.

The occurrence is hosted in a small elongate stock of granodiorite, near its eastern margin. This north-trending stock is 1.8 kilometres long and intrudes andesitic ash and lapilli tuff of the Upper Triassic Whistle Creek Formation (Nicola Group). The stock may be related to the Early Jurassic Pennask batholith, which surrounds the Nicola Group volcanics and sediments comprising this roof pendant.

Selected grab samples of sericite and chlorite-altered granodiorite, with clots and stringers of arsenopyrite, sphalerite and pyrite, assayed 1.6 grams per tonne gold and 5.0 grams per tonne silver (Assessment Report 22304, page 17, Table 2, sample PEN91-R8).

The volcanics near the granodiorite contact contain small, massive sulphide pods in skarn and quartz-arsenopyrite veins.

In 1991, selected grab samples of angular quartz vein float fragments up to 4 centimetres wide, with sparse to abundant arsenopyrite, yielded 3.77 grams per tonne gold and 3.2 grams per tonne silver (Assessment Report 22304, page 17, Table 2, sample PEN91-R9).

Work History

The area was originally explored in the 1960s for copper-molybdenum mineralization similar to that of the Brenda (MINFILE 092HNE047) deposit to the east.

During 1986 through 1990, Fairfield Minerals Ltd. completed prospecting in the area and subsequently staked the claims in 1990. During 1991 through 1995, Fairfield Minerals Ltd. conducted programs of prospecting, geochemical (rock, silt and soil) sampling and minor trenching on the area as the Pen claims.

In 2005, Charles Greig and Bernard Kreft staked the area over the old Pen 5 and 8 claims, which were renamed Puupster and Puupster 2, as part of the North Brenda property.

During 2006 through 2012, Bitterroot Resources completed programs of rock, silt and soil sampling, geological mapping, trenching, 147.6 line-kilometres of ground magnetic surveys and a 66.2 line-kilometre ground induced polarization survey on the area as the North Brenda property.

In 2016, Gorilla Minerals Corp. completed a soil and rock sampling program on the area as the New Brenda property. In 2018, Flow Metals Corp. completed a program of geological mapping, spectral and structural analysis and rock sampling on the New Brenda property. The following year, a program of geochemical (rock and soil) sampling, structural analysis and minor trenching was completed on the property.
