The Goat deposit is located about 34 kilometres northeast of Stewart, approximately 5 kilometres north of the Stewart highway (37A) and just south of the Goat Glacier.
The area is underlain by north striking, green andesitic agglomerates and minor intercalated siltstones of the Lower Jurassic Unuk River Formation (Hazelton Group). Just west of the mine area thick, massive volcanic breccias occur. Northwest trending quartz monzonite dikes intrude the volcanics. Several veins occur on the property.
The Goat deposit is a parallel series of polymetallic silver-gold-zinc-lead veins that consist of crudely laminated sulphide-quartz-siderite and gangue. The sulphides include coarse-grained sphalerite, disseminated and massive arsenopyrite and pyrite, tetrahedrite, freibergite and minor galena. Gangue minerals include siderite, quartz and minor epidote and calcite. Galena-lead isotope analyses indicates a Tertiary age for the mineralization (Fieldwork 1990, page 241).
The main veins (F and G veins) lie along irregular northeast-trending fractures in a 100 to 120-metre-wide, northwest trending shear zone in the volcanics. Rocks in the shear zone consist of variably schistose volcanics and chloritic and sericitic phyllonite (Minister of Mines Annual Report 1965). The veins average about 15 centimetres in width and transect the shearing and the dikes.
The F vein, traced for more than 120 metres, undulates northeast across the shear zone and dips 35 to 80 degrees northwest. The F vein terminates close to the limits of the shear zone. The G vein, traced for about 75 metres, is a branch vein on the hangingwall side of the F vein.
The Goat vein, comprising a 0.1 to 0.8-metre-wide quartz stringer vein, extends over a length of 240 metres between elevations of 1067 and 1189 metres. The quartz dominated vein contains disseminated to semi massive pyrite, galena and sphalerite. A channel sample, collected in 1946 from an adit at 1067 metres elevation above sea level, assayed nil gold, 75.4 grams per tonne silver, 0.07 per cent copper, 2.90 per cent lead, 3.9 per cent zinc and 0.05 per cent cadmium across a width of 0.71 metre (Minister of Mines Annual Report 1946, page 80).
A sample (44439) taken from the mill site in 1991 assayed 3.58 grams per tonne gold, 216.7 grams per tonne silver, 0.153 per cent copper, 0.18 per cent lead and 6.45 per cent zinc (Assessment Report 22040).
Proven and probable reserves in 1979 were 8800 tonnes grading 4782.9 grams per tonne silver and 10.6 grams per tonne gold (Northern Miner - March 1, 1979). Recorded production during the period 1975 and 1979 to 1981 was 1,794,049 grams of silver, 5475 grams of gold, 52,641 kilograms of zinc, 4071 kilograms of lead and 153 kilograms of copper.
Work History
The showings were staked in 1960 as the Surprise claim group by Newmont Mining and Granby Mining. The claims were restaked in 1963 as the Goat group. Noradco acquired the claims in 1964 and completed trenching, sampling and three drill holes on the property. In 1965, two adits were driven on the F vein and two raises were driven to the G vein. In 1968, an agreement with Shield Minerals Corp. ensured continued underground development. In 1971, Abitibi acquired the Shield Minerals interest and incorporated Nordore Mining Co. In 1974, Nordore rehabilitated the workings now on the Ken 1-4 and Goat A-H claims. In 1974, the Remus claims were acquired as a mill site; about 1770 tonnes of ore was stockpiled. In 1976, about 295 tonnes of ore was milled from a portable concentrator. Development work on the E vein recommenced in 1979 and "some" material was put through the concentrator. In 1980, underground development continued, and the mill operated for several months. The mill was destroyed by fire in 1981 and all work ceased. A geophysical survey was carried out over the property by Bond Gold in 1990. In 1991, Cameco conducted geochemical surveys and sampling on the Ken and Hugh claims. The property was staked by R. Kasum during 2003 and an option deal with Grizzly Diamonds Ltd. was made in late 2004. In 2005, a prospecting and sampling program was completed by Apex Geoscience Ltd. on behalf of Grizzly Diamonds Ltd.
Work by Decade Resources conducted during 2011 and 2016 was primarily focused on exploration for Kuroko type VMS deposits along the northern and western part of the property. Several different mineralization types were indicated from this work. Highlights of the previous Decade sampling included: 1) the presence of Kuroko type VMS mineralization along the western portion of the area and 2) the presence of high-grade silver with gold associated with lead - zinc bearing rocks along the northern part of the property. The 2011 sampling was carried out on float rocks in the valleys to cover as great an area as possible. In 2011, 226 samples were collected. Sampling of a calcareous mudstone with finely laminated and bedded sulphides yielded 33.4 grams per tonne silver, 0.70 per cent lead and 6.50 per cent zinc; sampling of dacitic rocks gave a high of 115.7 grams per tonne silver, 0.50 per cent lead and 6.5 per cent zinc within a breccia with strong hydrozincite staining (Assessment Reports 33053, 37324). In 2016, 18 float rock samples were collected in total, with 9 of these collected below the area of the underground workings, yielding up 2.3 grams per tonne gold, 100 grams per tonne silver, 0.65 per cent lead and 2.76 per cent zinc (Assessment Reports 36578). Samples were manganese stained, siderite rich quartz with variable brown coarse sphalerite. In 2016, a total of 9 samples were also collected in the North Goat area just over a kilometre north of those 9 samples collected below the underground workings. These samples yielded values up to 0.0067 grams per tonne gold, 3.8 grams per tonne silver and 0.0114 per cent zinc (Assessment Report 36578).
In the 2017 geochemical program, a total of 64 float and bedrock samples were collected within a few kilometres east and southeast of the Goat past producer. Sampling was carried out along moraines and valley bottoms extending from known gold-silver bearing areas on the property. Samples were taken of any pyritiferous, manganese stained or sulphide bearing bedrock or float boulders. Sampling indicated values ranging up to 2.02 grams per tonne gold, 136 grams per tonne silver, 0.28 per cent copper, 2.35 per cent lead and 3.51 per cent zinc (Assessment Report 37234).
