May 11, 2010 (J Bongfelt) - 'The showing consists of a pit 3x3x2m deep blasted into gabbro on the side of a low hill. Overburden covers the area to the south and west. The east and north are under the waters of a beaver pond. Disseminated pyrrhotite, chalcopyrite and minor pyrite occur across the entire 3m width of the pit. The gabbro is medium-grained with occasional pegmatitic phase. The pegmatite is characterized by amphibole crystals up to 2cm in length.' (Kenora Assessment File 52F10NW, VV-1, Eagle lake Resources Ltd.)
Nov 04, 2022 (Therese Pettigrew) - Pyrrhotite and chalcopyrite occur in Early Precambrian mafic to ultramafic gabbroic rock which intrude intermediate to felsic volcanics (SMDR 00489).

May 11, 2010 (J Bongfelt) - Harrison Beaver Pond Showing 1971: Nichro Mines received the following best recorded assay results from DDH #2: 0.33 % Cu & 0.12% Ni. * Several holes were drilled in this area in the early 1970's, one of which intersected a quartz vein containing 0.29 oz./ton Au within the shear zone. True width of the quartz is unknown; the vein does not outcrop. 1974: Nichro Mines Ltd. - a grab sample assayed 0.33% Cu and 0.37% Ni from a test pit at the edge of the beaver pond. The pit exposes a sheared zone in gabbro over a width of 7m. The zone strikes east-west and dips vertically. Mineralization consists of pyrrhotite, chalcopyrite and pentlandite in discrete shears over the full width of the pit. Early 1980's: Beth Canada re-assayed old core: .35% to .45% Cu and .14% to .18% Ni. Also, grab samples collected by Beth, near pit, assayed 150-600 ppb Au. 1987: In one hole of this zone, a 5-foot intersection of quartz was obtained. Three assays of this core were carried out for gold by Eagle Lake Resources Ltd.. The results for Au were: '0.31 oz./ton, 0.27 oz./ton and 0.30 oz./ton. This vein is not exposed on surface and therefore the orientation is not known. The anomalous gold values in the samples from the pit indicate this zone has both gold and platinum potential.' (There is a map in Kenora AF 52F/10NW, V V-2, Eagle Lake Resources Ltd. titled 'Steep Rock - Harrison Prospect' that outlines the three Steep Rock showings with recorded assay figures, however, a copper grade of 0.40% and a nickel grade of 0.24% is no where to be found except on this map. Therefore, we cannot verify these assay grades.) (a. Kenora Historical File, F10NW00121, Steep Rock; b. Kenora Assessment File 52F10NW, W-1 & W-2, Nichro Mines Ltd.; c.

Nov 24, 2017 (Therese Pettigrew) - The #2 Showing is located at 7+25NW, 0+50SW, exposed in outcrop on the shore of the beaver pond. The showing consists of disseminated pyrite, pyrrhotite, chalcopyrite, and likely pentlandite in gabbro and a hybrid rock of gabbro and volcanics mixed. Previous assays from samples across this zone have values of 7-87 ppb Au with <2 ppb Pd and 10 ppb Pt. The #3 Showing was discovered at 10+1-NW, 4_75NE on the gently sloping southwestern flank of a ridge. The zone is exposed in a small outcrop. The zone consists of sheared, bleached, altered felsic volcanics. The rocks has been carbonated and silicified. Fine pyrite is disseminated throughout the exposed width of 10 feet. Assays from this zone gave results of 253 and 222 ppb Au (AFRI 52F10NW0061).
