Point Location Description: Precise
Location Method: Conversion from MDI
Access Description: An all-weather gravel access road runs from Enterprise to Parham. The prospect is accessible from a vehicle trail which passes south of Slave Lake and joins the access road approximately 10 road kilometres north of the CPR crossing in northeast Camden East Township.
Pre 1916: 2 pits were opened by unknown operators. 1935: Mr. G.A. Beausoleil acquired the property and carried out preliminary exploration work and transferred interest to Miss C.L. Beausoleil. 1936-1937: Lennox Mines Limited bought the property and sold it to Lennox Mines Company Limited. One shaft was excavated to a depth of 50 feet, and 60 feet of drifting was completed. Two other shafts were also deepened. About 1000 feet of diamond drilling was completed. 1938-1948: Lennox Mines Co. Ltd. carried out an unspecified amount of trenching. 1947-48: Lennox Mines Co. Ltd. completed a diamond drill program brought the total amount of drilling up to 5000 feet. At this time, the shaft was dewatered and surface mapping and prospecting was carried out. 1967: P.W. Kingston produced a geological map of the property (OFR 5548, p.142).

Oct 23, 2019 (Sheree Hinz) - The geology of the area is dominated by the granitic gneisses of the Hinchinbrooke and MacLean Intrusions. The Hinchinbrooke granite, a circular body of 27km x 22km, slightly elongated in the NE direction, crosscuts a sequence of mafic meta-volcanic rocks (amphibolite schists and gneisses), marbles and clastic meta-sediments (paragneiss and politic-schists). The Hinchinbrooke Granite contains a great number of xenoliths of its hosts rocks. These xenoliths are typically elongated (flattened) in the NS to NE direction and vary greatly in size from less than 100m to 15km in length. The property is situated within one of these xenoliths in the western part of the Hinchinbrooke intrusion. Metamorphism in the area is generally upper amphibolite to granulite.

Oct 23, 2019 (Sheree Hinz) - The zinc mineralization consists of heavily disseminated bands of sphalerite up to 20cm, in white dolomitic marble. Individual bands contain 30-80% dark red, fine to medium grained sphalerite with grains being coarser in the lower grade bands. A chip sample of mineralization from zone 2 is reported to have returned an assay of 19.6% Zn, 42ppm Pb and 0.1 oz/t Ag while a grab sample of the rock dump returned 44.4% Zn, 17ppm Pb, 430 ppm Cu, and 980 ppm Cd.
