The MAC showing is located approximately 21.5 kilometres northwest of Peachland and approximately 500 metres southwest of the Brenda mine mill site. The area covered by the MAC claims adjoins the Brenda mine property (MINFILE 092HNE047).
This area is underlain by granodiorite and porphyritic quartz diorite of the Upper Triassic to Lower Jurassic Pennask Batholith, which is locally known as the Brenda stock.
Fractured granodiorite contains small amounts of chalcopyrite and pyrite on or near veins and stockworks similar to those on the Brenda mine property (Minister of Mines Annual Report 1966, page 185). Lamprophyre and trachyte porphyry dikes trend east and are approximately 1 metre wide.
Work History
The MAC claims were held by Anuk River Mines Ltd. during the exploration boom around the Brenda mine in the late 1960s. In 1966, they carried out a major program that included 23 percussion drillholes and 1207 metres of diamond drilling in 15 holes. No assessment reports were filed on this program; however, other sources (Minister of Mines Annual Report 1966, page 185) state that all of the drillholes were collared in granodiorite, and that small amounts of copper and subeconomic molybdenum were encountered. Notations on a surface plan of the property indicate that drillcores assayed as high as 0.152 per cent molybdenite in DDH 11, 0.113 per cent molybdenite in hole DDH 6 and 0.11 per cent molybdenite in hole DDH 8; copper values were less than 0.2 per cent (Property File - Anuk River Mines Ltd.(1966): Surface Plan). The plan does not indicate if these are average or best assays.
In 1981, Esso Resources Canada Ltd. completed an 810 line-kilometre airborne magnetic and electromagnetic survey on the area.
During 1986 through 1990, Fairfield Minerals Ltd. completed prospecting in the area and subsequently staked the claims in 1990. During 1991 through 1996, Fairfield Minerals Ltd. conducted programs of prospecting, geochemical (rock, silt and soil) sampling and minor trenching on the area as the Pen claims. In 1991, a subcrop grab sample (PEN91-R1) of quartz-carbonate veins in an altered volcanic, located approximately 1.1 kilometres south of the Mac occurrence, yielded 0.48 gram per tonne gold (Assessment Report 22304).
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.
