Dec 07, 2005 (G Meyer) - The overall strike direction of the shear zone, along which the scheelite-gold mineralized zone occurs, is 316 and the dip is steep to the east. Locally, the zone is deformed with the development of small folds.

Dec 07, 2005 (G Meyer) - A review of a geological map by Johns (2000) suggests that the gold-scheelite showings occur in intermediate to mafic metavolcanic rock.

May 01, 2024 (Nazha Sabiri) - DDH CO7-1 (317 m) intersected the main mineralization zone at the vertical depth of 180 m. Basalt sample from this zone returned 3.2 g/t Au over 1.45 m; another sample from a porphyritic andesite mineralized shear assayed 0.63 over 1.4 m (same hole) (20000003816). Grab sample 1611 from the Sheelite Zone assayed 1526 ppm WO3, 1.46 ppm Au and 2.3 ppm Ag (41P11SE2036).
Dec 07, 2005 (G Meyer) - At this site overburden stripping and several pits expose a strongly carbonatized, sericitized zone with disseminated pyrite and a stockwork of quartz-carbonate veins.
