The North Brenda-Central showing is located approximately 5 kilometres north of the Brenda mine open pit (MINFILE 092HNE047) and 25 kilometres northwest of Peachland.

The area is underlain by porphyritic quartz diorite of the Lower Jurassic Pennask Batholith, locally known as the Brenda stock. Alteration of the quartz diorite is generally confined to fractures and narrow alteration envelopes around those fractures. Four main alteration assemblages have been noted; quartz-hematite-pyrite, chlorite-epidote-potassium feldspar, biotite-chalcopyrite and chlorite. The dominant trend of these fractures is northwest, in contrast to the northeast trend at the Brenda mine.

Locally, chalcopyrite mineralization is present as very thin fracture fillings with biotite. Cross-cutting relationships indicate that the chalcopyrite fracture fillings are the oldest. Malachite is found on weathered surfaces.

In the 1960s, a drill hole (PH9) intercepted 24.0 metres averaging 0.34 per cent copper (Assessment Report 16750).

Work History

The occurrence was part of the extensive property holdings of Noranda Exploration Company Ltd in the 1960s. Numerous trenches, roads and drill holes were left in this general area by Noranda; however, the results of this work were not filed for assessment.

In 1967, Lakeland Base Metals completed a program of soil sampling on the area immediately east of the occurrence as the JO claims.

In 1970, Arrow Inter-America completed an airborne magnetic survey, totalling 752 line-kilometres, on the area as the Tic and Toc claims.

During 1974 through 1976, Canadian Occidental Petroleum carried out geological mapping and rock and soil geochemical surveys on the area as the Tre claims.

In 1987, Brenda Mines Ltd. completed a program of geological mapping, soil sampling, ground magnetic and induced polarization surveys and drilling on the area as the North Brenda (NB claims) 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 2019, C.J. Greig completed a soil sampling program on the area as the Trepanier property.
