Exploration History

1967: Several occurrences of copper and nickel mineralization were found by A. Kozowy in the vicinity of Nabish Lake, about ten miles southwest of Dryden. 1968-9: Trenching, magnetic and electromagnetic surveys by Hollinger Mines Ltd. Hollinger drilled 3 DDH totalling 430.9 m. 1971: Lynx-Canada Ltd. optioned claims in this area from Alex Kozowy and Alex Glatz of Dryden and drilled at least 2 DDH totalling 176.2 m. 1990: Glatz and Kozowy conducted magnetometer and VLF-EM surveys. 1991: Societe Miniere Mimiska Inc. conducted mag and VLF-EM surveys and drilled 7 DDH totalling 609.6 m.

Geology Comments

Mar 22, 2010 (J Bongfelt) - Sulphide mineralization occurs along a north-trending breccia zone composed of sub-rounded andesitic fragments in a coarser dioritic matrix. The suphides are mainly nickeliferous pyrrhotite, lesser amounts of chalcopyrite and pyrite, and minor pentlandite. (Mineral Resource Circular No. 12, p. 164).

Lithology

Lithology Comments

Mar 23, 2010 (J Bongfelt) - The Kozowy property is underlain by metavolcanic rocks, with the sulphides occurring along a north-trending breccia zone composed of sub-rounded andesitic fragments in a coarser dioritic matrix. The zone appears to be about 150 feet wide and may possibly lie between two north-south faults. Bedding planes in nearby agglomerate strike east-west. A number of test pits have been sunk in the breccia zone. Sulphides are mostly nickeliferous pyrrhotite with less chalcopyrite and pyrite and minor pentlandite. The sulphides occur predominantly in the gabbroic matrix of the breccia and are also concentrated along intertwining slip planes. (MP 16, 1967, p.6-7)

Mineralization

Mineralization Comments

Mar 23, 2010 (J Bongfelt) - Grab samples up to 3% Ni and 0.5% Cu have been reported. Dimensions of the mineralized zone are not known. (Mineral Resource Circular No. 12, 1969, p.164) 1968: Diamond Drill Report of Kozowy Option Hole No. PSK #1 - 1.23% Cu and 1.76% Ni Hole No. PSK #2 - .09% Ni 1988: Four samples were taken from a blast of the new Nabish sulphide showing by Alex Kozowy: 2310, 1875, 979 ppm Ni, and 12900 and 4300 ppm Cu. 1990: new stripping and trenching by Mr. Alex Kozowy of Dryden resulted in the following assays: Trench #1 = best assays of 0.018 oz/ton Au, 4.00% Cu, and 2.19% Ni Trench #2 = best assays of 0.017 oz/ton Au, 2.20 % Cu, and 1.03% Ni Test Pits 1, 2, & 3 = best assays of 0.79% Cu, and 2.01% Ni 1990: C.E. Blackburn accompanied Alex Kozowy to the K40210 Occurrence on Nov. 13, 1990 and assayed samples reporting the following best numbers: 3.680 % Cu, and 2.588% Ni

Nov 24, 2017 (Therese Pettigrew) - Copper-nickel mineralization appears to be spatially associated with the quartz diorite breccia. Spectacular pyrrhotite-chalcopyrite mineralization is present at Trench 1. Up to 25% chalcopyrite and 60% pyrrhotite was observed. Semi-massive sulphide containing blue quartz eyes and altered chloritic wallrock was observed in Trench 1. Grab samples returned up to 6.5% Cu and 3.5% Ni. Platinum and palladium values ranged up to 280 ppb (AFRI 52F10NW0056). Significant drill hole intersections from the 1991 program included 0.91% Ni with 0.52% Cu over 1.52 m from a depth of 1.40 m to 2.92 m, and 0.62% Ni with 0.39% Cu over 1.28 m from a depth of 5.00 m to 6.28 m in hole CB-91-01. These values were obtained under the main trench. A vertical hole intersected 0.53% Ni over 0.65 m from a depth of 4.12 m to 4.77 m in drill hole CB-91-05 (AFRI 52F10NW0056).
