The Silvergal occurrence is located at an elevation of approximately 1040 metres on a south-southwest–facing slope, west of Russel Creek and approximately 2.5 kilometres northwest of the west end of East Barriere Lake.

The area is underlain by the Lower Cambrian Eagle Bay assemblage including the Tshinakin Limestone member and greenschist metamorphic rocks of the Johnson Lake unit. The rocks include calcareous chlorite schist and fragmental schist derived from mafic to intermediate volcanic and volcaniclastic rocks. The limestone is massive, light grey and finely crystalline.

Locally, a limestone hosts quartz veins and veinlets with massive galena, chalcopyrite, malachite, and an unidentified silver mineral. The area of quartz veining has been exposed over a width of 6 metres and strikes 350 degrees with a near vertical dip.

In 2011, five grab samples (BR11Q9D, BR11Q9C, BR11Q9A, BR11-104 and BR11-106) yielded from 5.8 to 220 grams per tonne silver with up to 0.747 per cent copper, 12.4 per cent lead, 0.308 per cent zinc and greater than 0.200 antimony (Assessment Report 32383).

In 2017, a sample (BR17-AP04) assayed 0.43 gram per tonne gold, 357 grams per tonne silver and 20 per cent lead (Assessment Report 37066).

Work History

In 1971, Duncanex Resources completed a program of silt and soil sampling on the area as the C&G and Den claims.

In 1984, Noranda Mining and Exploration Inc. completed a program of geochemical (rock and soil) sampling, geological mapping, airborne and ground geophysical surveys and two drillholes, totalling 132.2 metres, on the area as the Cad claims. The following year, a further two diamond drill holes were completed on the Cad claims.

In 1987, Merritech Development Corp. completed three diamond drill holes, totalling 394.1 metres, on the Cad claim group.

During 1988 through 1990, Minnova Inc., on the behalf of National Resource Explorations Ltd., completed programs of rock sampling, geological mapping, ground geophysical surveys and five diamond drill holes, totalling 524.6, on the area surrounding area as the Biere property.

In 1992, the area was prospected, mapped and rock sampled by Rich Coast Resources Ltd. as the Cad claims.

In 2010 and 2011, Astral Mining Corp. completed programs of prospecting, geochemical (rock, silt, and soil) sampling, hand trenching and 1334 line-kilometre airborne magnetic and electromagnetic surveys on the area as the Barriere Ridge and Honeymoon properties.

In 2013, Astral Mining Corp. completed a further 1121.4 line-kilometre airborne electromagnetic survey on the Barriere Ridge and Honeymoon properties. Later that year, a program of prospecting and geochemical (rock, silt, and soil) sampling was performed by D.J. Piggin.

During 2014 through 2018, programs of prospecting, geological mapping, hand trenching and geochemical (rock and soil) sampling were completed on the Barriere Ridge property.
