Feb 26, 2021 (Sheree Hinz) - The property is underlain by marble interbedded with narrow bands of biotite-quartzo-feldspathic gneiss. Other quartz veins, up to 80 cm wide, pinch and swell out along strike, quartz stringers are erratically distributed on the property, and the mineralization appears to be widely scattered. Two pits that comprise the surface exposure of the deposit are underlain by dolomitic marble. A quartz vein exposed in the accessible pit is about 0.70 m wide and parallels the strike of the country rock.

Feb 26, 2021 (Sheree Hinz) - A quartz vein in one of the pits is mineralized with stringers and small clusters of chalcopyrite, and patches of malachite. A chalcopyrite-bearing quartz sample (LBP-0430) collected in 1987 (R241, pg.48) from the ore dump contained 13.0 ppm gold, 102 ppm silver, 0.59% copper, and traces of lead. Another sample of marble-hosted quartz vein (LBP-0694) collected in 1987 (R241, pg.36) assayed 10.1 ppm Au with traces of Cu.
