The High Grade vein is located 1 kilometre north of Peak Lake.
The area is underlain by rocks of the Paleozoic Sicker Group comprising deformed breccia, tuff, argillite, greenstone, greenschist, narrow dykes of andesite porphyry, and argillaceous and calcareous sedimentary rocks. There are numerous faults and shear zones in the area suggesting a north-northeast fault through the Peak Lake area. A number of quartz veins and carbonatized zones are present.
The High Grade vein is hosted within a tightly folded sequence of cherty tuffs. The zone is characterized by tightly folded and fault bounded volcaniclastic rocks with minor pillow basalt of the Upper Devonian McLaughlin Ridge Formation, Sicker Group. Numerous quartz veins cut the volcaniclastic rocks and frequently yield anomalous values for gold upon geochemical analysis. The zone is broadly defined as having an average width of 200 metres, extending 700 metres northeast. The vein, open to the southwest, strikes 175 degrees and dips 32 degrees east. The vein is mineralized with sphalerite, pyrite, chalcopyrite and arsenopyrite.
A grab sample (16215B) from the vein assayed 24.5 grams per tonne gold, 63.1 grams per tonne silver, 1.0 per cent copper and 21.28 per cent zinc (Assessment Report 17207).
In 1987, drilling to test the downdip extension of the surface exposed the ‘High Grade’ vein, which yielded intercepts of 1.40, 2.31 and 3.28 grams per tonne gold over 0.05, 0.08 and 0.07 metre in holes EM87-1, -3 and -5, respectively, whereas a drillhole (EM87-2) collared on a nearby gold-in-soil and induced polarization anomaly yielded intercepts of 1.18, 1.98 and 1.22 grams per tonne gold, 22.3, 20.0 and 18.5 grams per tonne silver, 0.363,0.432 and 0.332 per cent copper with 0.01, 6.43 and 0.01 per cent zinc over 0.13, 0.18 and 0.11 metre, respectively (D.G.

Work History
During 1983 through 1989, Au Resources Ltd. completed programs of prospecting, geochemical sampling, geological mapping, trenching, an induced polarization survey and twelve diamond drill holes, totalling 1511.8 metres, on the Emma claims.
In 2016, Karmamount Mineral Exploration Inc. completed a program of prospecting and rock sampling on the area.
In 2020, Corcel Explorations Inc. completed an 811.3 line-kilometre airborne magnetic survey on the area as the Peak property.
