The Magee occurrence, located 4 kilometres east-southeast of Stewart, was discovered in 1980.
The showing consists of a 0.3 metre wide tetrahedrite bearing quartz vein striking 128 degrees and dipping 18 degrees northeast. The vein is hosted in dacitic tuff of the Lower Jurassic Unuk River Formation (Hazelton Group). A sample assayed 2.58 grams per tonne silver, 0.46 per cent copper and trace lead (Assessment Report 8650, page 9). In 1986, a rock sample (#2173) by Teuton Resources Corp. assayed 15.2 grams per tonne silver (Assessment Report 15574).
Another zone of mineralization, referred to as the Ma 1 zone and located in the approximate area of the Magee occurrence, comprises a network of shear zones, spaced 20 to 50 metres part and trending northeast to northwest and hosts a series of northwest-trending quartz veins, up to 0.6 metre wide, with sparse sulphides (pyrite and chalcopyrite) in a fractured dacitic tuff. Within the shear zones, wallrock fragments set in a gouge or clay mix contain chlorite and specular hematite.
In 1991, a rock sample (88001) assayed 1.31 per cent copper and 19.7 grams per tonne silver over 0.6 metre (Assessment Report 21101).
Work History
In 1980, Western Hemisphere Mining Corporation conducted reconnaissance geological and geochemical surveys on the Magee claims. During 1984 through 1987, Teuton Resources Corp. completed programs of prospecting, geochemical (rock, soil and stream sediment) sampling and a 24 line-kilometre airborne geophysical survey on the area.
In 1990, White Channel Resources Incorporated conducted geological mapping, soil and stream sediment sampling on the Ma and Gee claims. Also at this time, Amphora Resources completed an 8.1 line-kilometre airborne magnetic and electromagnetic (VLF) survey on the area. In 1991, White Channel Resources Inc. completed a program of geological mapping and geochemical (rock, silt and soil) sampling on the area as the Ma 1 claim.
In 2018, Granby Gold Inc. completed an 88.25 line-kilometre airborne magnetic and gamma-ray spectrometry survey on the area.
