Oct 24, 2022 (Therese Pettigrew) - The mafic volcanics outcrop west of L10+00mE and north of the base line east of L10+00mE (Dwg. 6676). The mafic volcanics are predominantly weakly altered massive flows. They are very fine grained, dark green, weakly mineralized (nil to trace pyrite) and weakly foliated. Flows of andesitic and dacitic composition outcrop very locally. Mafic to intermediate crystal tuffs and agglomerate also outcrop locally within the mafic flow sequence. The crystal tuffs (pyroclastic flows) contain approximately 5-15% fine-grained feldspar phenocrysts. The agglomerates contain 5-10% lapilli-sized feldspathic fragments. Strongly foliated mafic volcanics were mapped as mafic tuffs. These rocks have a tuffaceous appearance due to their strong foliation but may be sheared or schistose flows. The sediments outcrop predominantly east of L9+00mE and south of the base line (Dwg. 6676). Greywacke and argillite are the most common sediments observed on the property. The greywackes are very fine-grained, light to dark grey and moderately foliated. Occasionally the greywackes are interbedded with argillite. The argillites (varved slates of Johnston, 1972) are very fine-grained, dark green, thinly bedded/laminated and moderately to strongly foliated. Both the greywacke and argillites are non to weakly mineralized with pyrite (nil to trace) (Assessment report 52J04SE0001).

Oct 24, 2022 (Therese Pettigrew) - The strongest altered and mineralized rocks on the property were observed at the exposed volcanic/sediment contact in the main trench located at L9+50mE; 0+0SmS (Dwg. 6676). The hanging wall (trench-north) is sheared mafic volcanic. The central portion of the trench is underlain by a strongly silicified-carbonate alteration zone, approximately 5 m in width. This zone is mineralized with 1-3% pyrite and trace molybdenite. Initial grab samples of mineralized rock taken from the trench returned values of 2.9 to 4.4 g/t Au. A set of near continuous chips taken over 1 m lengths through the mineralized/altered zone returned an average of 1.5 g Au/ton over 5 meters. The footwall of the zone is a unit of sericite schist with weak pyrite mineralization (trace to 1%). Grab samples taken in this section only returned up to 14 ppb Au. The strongly serialized footwall rock is assumed to be a highly altered sediment or feldspar porphyry (Assessment report 52J04SE0001). Gold values (2.9 to 4.4 g/t Au) occur within a carbonate silica-altered sheared contact zone between volcanics and sediments at the main trench on the property. The contact zone has pyrite and molybdenite mineralization and silicification. DDH MN-2 returned up to 2.03 ppm Au over 1 m from strongly silicified quartz-carbonate veins with 3-5% pyrite and locally up to 10% pyrite. DDH MN-4 returned up to 2.14 ppm Au over 0.6 m from the contact zone with quartz-carbonate stringers, 3% pyrite and trace chalcopyrite (Assessment report 52J04SW8926). Sampling done by Heritage Mining in 2022 returned assays of 1.27, 1.63, and 1.91 g/t Au (Heritage Mining news release Oct 19, 2022). Copper mineralization is found in Early Precambrian quartz-feldspar porphyry. Disseminated pyrite and chalcopyrite were identified. Gold occurs in carbonate zones of narrow width, ath the contact between Early Precambrian metavolcanics and sediments. Gold sampling gave a high of 0.2 oz/t Au over a narrow width (SDMR 00525). Grab samples assayed 0.44% and 2.56% Cu and 0.16 and 0.26 oz/t Ag (King, 1970).
Jul 14, 2022 (Q Unknown) - 1951: 225 samples taken, best assay 0.2 oz Au/ton.
