Point Location Description: Location taken as the location of the discovery hole
Location Method: Based on Assessment
Access Description: Access to the NW quadrant of Tully Tp is from the south where bush trails northwards from the end of the gravel road which ends at the Texmont Deposit. An alternate access is from the east where bush trails lead west from the end of the gravel road passing by Ice Chest Lake and Roy Lake.
1983: Newmont Exploration - diamond drilling intersected gold and zinc-copper values.

Nov 14, 2022 (Q Unknown) - Drilling in 1983 (MN83-6, 7, 8, 9 and 10) as follow-up to the discovery hold also intersected gold values. The more significant assays follow: MN83-1: 2.7% Zn, 0.7% Cu/3.5 ft; 4.65 g/t Au/2.25 ft, 1.39 g/t Au/2.75 ft, 1.03 g/t Au/2 ft, 1.31 g/t Au/3 ft, and 3.02 g/t Au/20 ft, (includes 6.98 g/t Au/5 ft); MN83-6; 788 ppb Au/20.5 ft and 242 ppb Au/8 ft; MN83-7: 1.33 g/t Au/5.9 ft; MN83-8: 1.6 g/t Au /16.6 ft; MN83-9: 4.99 g/t Au/3.6 ft, 2.11 g/t Au/5.2 ft, 1.10 g/t Au/3.3 t and 1.21 g/t Au/4.5 ft; and MN83-10: 247 ppb Au/46.6 ft and 1.29 g/t Au/4 ft. Much of this drilling was done on a wide spacing of 400 ft centres. The gold mineralization in hole MN83-1 was hosted by silicified, carbonatized basalt containing abundant pyrite and arsenopyrite with lesser quartz-ankerite stockworks. The zinc-copper value in hole MN83-1 was hosted by a massive pyrite unit which the drill log describes as infusion in sediment to tuffaceous unit. The flanking units are an iron carbonatized ultramafic flow uphole, and aluecoxene basalt downhole.
