Geological Age: Archean
Dec 07, 2005 (D Farrow) - The deposit is located in a volcanic sequence about 1.5 km wide comprising massive pillowed, often amygdaloidal flows interlayered with andesitic tuffs, lapilli tuff and agglomerate. This northeasterly striking volcanic sequence is intruded by several granodiorite sills which are crosscut by and contain northeasterly-trending tension fractures occupied by quartz veining up to 25 cm in width. Quartz-feldspar porphyry dykes also crosscut the metavolcanic sequence. The major auriferous granodiorite dyke on the Windward and Goldlund properties varies between 30 and 90 metres in width and follows a contact between tuff and pillow lava which has been traced for 3.2 km along strike. Gold in quartz veins is associated with pyrite, lead telluride and sometimes sphalerite.

Dec 07, 2005 (D Farrow) - 1980: VARIOUS DDH INTERSECTIONS - UP TO 9.49 OZ AU/TON OVER 0.7 FT (# 80-37).
Jun 29, 2020 (Therese Pettigrew) - Gold-bearing quartz veins occur as quartz-filled fractures contained within granodiorite dykes. Three parallel granodiorite dykes dip 85-87 degrees southwards and are 9-15 m thick, fractured, silicified, and mineralized with gold (Assessment report 52F16NW0040). DDH GL-17-062 returned 1.44 g/t Au over 12 m including 5.24 g/t Au over 2 m. DDH GL-17-063 returned 2.44 g/t Au over 18 m including 6.65 g/t Au over 2 m. DDH GL-17-065 returned 1.32 g/t Au over 90 m including 11.82 g/t Au over 2 m. DDH GL-17-068 returned 0.91 g/t Au over 68 m including 16.06 g/t Au over 2 m. GL-17-069 returned 1.51 g/t Au over 66 m including 13.93 g/t Au over 2 m. GL-17-076 returned 3.44 g/t Au over 8 m including 12.4 g/t Au over 2 m (Assessment report 20000015783).
Dec 07, 2005 (D Farrow) - Associated alteration includes pyritization, silicification and some carbonatization.
