The Pen 8 occurrence is 1.2 kilometres southeast of the summit of Pennask Mountain and 500 metres west-northwest of Hidden Lake.

The showing occurs in tuffaceous siltstone and argillite of the Upper Triassic Whistle Creek Formation (Nicola Group), at the south end of a small north-trending stock of granodiorite, 1.8 kilometres long. This stock may be related to the Lower Jurassic Pennask Batholith, which surrounds the Nicola Group volcanics and sediments comprising this roof pendant. The siltstone and argillite are hornfelsed and intercalated with calc-silicate and quartz-garnet bands. The bands are mineralized with disseminated pyrrhotite, arsenopyrite, chalcopyrite and sphalerite (?).

To the southwest of the previous zone, near the southeast shore of Hidden Lake, sulphide pods, less than 1 metre in diameter, comprising pyrite, pyrrotite and arsenopyrite are reported to be exposed by a roadcut.

Selected grab samples (PEN91-R19) of outcrop and talus analyzed 0.0075 gram per tonne gold and 1.0 gram per tonne silver, whereas a float sample (PEN91-R11) of quartz vein fragments with disseminated pyrite and arsenopyrite, located near the eastern shore Hidden Lake and approximately 950 metres east-southeast of the Pen 8 occurrence, yielded 1.69 grams per tonne gold (Assessment Report 22304, page 18, Table 2).

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.
