Oct 29, 2021 (Therese Pettigrew) - The Eyapamikama Lake area is at the northwest end of the North Caribou Lake greenstone belt. The greenstone belt is structurally a large synclinorium. The synclinorium has a rim of predominantly mafic metavolcanics and a core predominantly of metasediments. Iron formations occur at and near the contact of the mafic metavolcanics with the metasediments. The Seeseep Lake gold occurrence is situated on the south flank of the synclinorium within the mafic metavolcanics.

Oct 29, 2021 (Therese Pettigrew) - Sample 58 on OGS map P2834 returned 4.63 ppm Au from a mafic metavolcanic with sulphides and iron staining. Sample 57 returned 0.605 ppm au from a quartz vein without visible mineralization (Barlett et al., 1985). Approximately 150 m to the north of where the location of sample No. 58 is indicated by Bartlett (1985), a pyrite occurrence symbol is indicated on the map. At this location, narrow shear zones striking 100 degrees and dipping 80 degrees S cut the mafic metavolcanics. The shear zones contain 1 to 3 percent disseminated pyrite and many quartz stringers. Geocanex Inc. took a few grab samples from the shear zones. The gold content of the samples ranged up to 995 ppb gold. Geocanex Inc. traced the zone in outcrops to the west for approximately 425 m (Janes et al., 1997).
