The Goat occurrence is located at an elevation of approximately 1700 to 1800 metres on a north-trending ridge, east of the Finlay River and approximately 8.5 kilometres east-northeast of its confluence with the Firesteel River, about 275 kilometres north of the community of Smithers.

Regionally, the area is situated within a Mesozoic volcanic arc assemblage, which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Paleogene sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Stuhini Group andesite flows and pyroclastic rocks, and marine sedimentary and volcanic rocks of the Lower to Middle Jurassic Hazelton Group. These rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calc-alkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults that define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high-angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The occurrence area is underlain by grey to green andesitic flows and tuffs of the Stuhini Group immediately south of a thrust fault contact with crystal ash tuffs and flows and associated epiclastics of the Toodoggone Formation. Stuhini Group hostrocks strike northwest and dip 78 degrees southwest to 79 degrees northeast.

Locally, dark green andesitic tuffs host three east trending, subparallel quartz-carbonate veins or vein systems, which are exposed over a north-south distance of approximately 175 metres. The veins contain pyrite, chalcopyrite, galena, sphalerite and tetrahedrite with associated quartz-sericite-calcite-pyrite-ankerite alteration in east-trending shears. The veins vary in width and length, with maximum widths of 1 to 4 metres, and have been traced along strike for 100 to 250 metres. The veins strike 070 to 115 degrees and dip near vertically to 42 degrees south. The quartz is both milky white to grey in colour and also of the amethystine variety with banded chalcedony; open-spaced fillings also occur. Malachite and hematite staining are common. Propylitic and local clay alteration are associated with the veins.

The main (southernmost) Goat occurrence vein, referred to as the Black vein, has been traced along strike for approximately 150 metres and varies from 0.05 to 0.40 metres in width. The Mid vein, located approximately 100 metres to the north of the Black vein, varies from 0.20 to 0.35 metres in width and has been traced for approximately 200 metres along strike. A third subparallel vein is located a further 75 metres to the north and downslope of the Mid vein.

In 1981, a float sample (SC-40-81-9) of vuggy quartz-calcite vein with galena, sphalerite and malachite staining assayed 88.9 grams per tonne silver (Assessment Report 10705). In 1987, a considerable amount of rock chip sampling was conducted on veins and country rock from this zone, yielding up to 209.9 grams per tonne gold, 204.7 grams per tonne silver, 0.206 per cent zinc, 0.447 per cent lead and 0.085 per cent copper from the north vein (sample R-6925). A second sample (6926), taken to the east along the same vein, assayed 35.4 grams per tonne silver, 3.60 per cent zinc, 2.529 per cent lead, 0.023 per cent copper and trace gold (Assessment Report 17459).

In 1999, a sample (BK-15) from a 0.10 to 0.15 metre wide and 25-metre-long vein, located at the southern end of the mineralized zone, assayed 39.2 grams per tonne gold and 108.0 grams per tonne silver with low base metal values, whereas another sample (DR-14) taken from a 0.20 to 0.35 metre wide and 30-metre-long vein, located 100 metres to the north and downslope of the previous vein, yielded 20.3 grams per tonne gold, 225.0 grams per tonne silver, 11.85 per cent lead and 16.27 per cent zinc (Assessment Report 26251). Another 0.15-metre-wide vein, located a further 75 metres to the north and downslope of the previous vein, yielded values up to 0.67 gram per tonne gold, 92.5 grams per tonne silver, 0.823 per cent copper and 5.89 per cent lead (sample DR-2; Assessment Report 26251).

In 2000, sampling and hand trenching of the Black vein yielded values from 0.07 to 297.93 grams per tonne gold and 0.4 to 272.4 grams per tonne silver over a strike length of 115 metres, whereas the easternmost sample, taken over 0.15 to 0.20 metres, yielded 25.18 grams per tonne gold and 557.3 grams per tonne silver (Assessment Report 26545). Also at this time, sampling of the Mid vein yielded up to 0.390 per cent copper, 0.964 per cent lead, 0.460 per cent zinc and 33.5 grams per tonne silver over 0.5 metre (Assessment Report 26545). In 2002, chip sampling across the veins yielded up to 396.5 grams per tonne silver, 165.8 grams per tonne gold, 0.01 per cent copper, 3.92 per cent lead and 9.61 per cent zinc (sample 02DB-134; Assessment Report 27160). In 2003, sampling of the west and east ends of the Black vein yielded up to 297.93 and 165.87 grams per tonne gold with 272.4 and 396.5 grams per tonne silver, respectively, whereas samples of the Mid and northernmost veins yielded up to 20.27 and 0.67 grams per tonne gold with 225.1 and 92.5 grams per tonne silver, respectively (Assessment Report 27429). Another sample, taken approximately 500 metres to the north-northeast yielded 1.01 grams per tonne gold (Assessment Report 27429).

In 1980, initial silt sampling of the area by Serem Ltd., the predecessor to Cheni Gold Mines Inc., resulted in the staking of the Wrich claims in 1981. Subsequent work, during 1982 through 1985, included geological mapping, prospecting, rock and soil geochemical sampling and geophysics, consisting of VLF-EM and VLF-EMR surveys. In 1987, Cheni conducted a program of rock and soil sampling, geological mapping. An option agreement was made between Skylark Resources Ltd. and Cheni Gold Mines Inc. following this program. The 1988 exploration program by Skylark on the Wrich claim consisted of drilling 10 BQ thin-wall diamond-drill holes, totalling 963.35 metres. Additional surveys conducted during the 1988 program included geological mapping, geochemical (rock, soil and silt) surveys and geophysical surveys consisting of VLF-EMR and magnetometer.

During 1997 through 2003, Stealth Mining Corp., on behalf of Electrum Resource Corp., completed programs of rock and soil sampling, geological mapping and ground geophysical surveys on the area. In 2009, Gold Fields Toodoggone Exploration Corp. completed a program of rock and silt sampling, geological mapping, a 180.8 line kilometre ground induced polarization survey and a 2778.0 line kilometre airborne magnetic survey on the area as part of the Pine property. During 2016 through 2018, Amarc Resources Ltd. completed programs of soil and rock sampling, geological mapping, 115.0 line kilometres of ground induced polarization surveys and 1940.0 line kilometres of airborne magnetic surveys on the area as the Joy property.
