The Tamrak (L.3341) occurrence is located at an elevation of approximately 880 metres on a northeast-trending ridge, south of Lendrum Creek and approximately 4.8 kilometres north-northwest of Ainsworth.

Regionally, the area is underlain by hornblende schists, limestone and banded quartzite of the Upper Mississippian to Permian Milford Formation and basaltic volcanic rocks of the Carboniferous to Permian Kaslo Group. Granodioritic intrusive rocks of the Middle Jurassic Nelson Batholith are exposed to the west.

From 1949 to 1951, 21 tonnes of ore were shipped, resulting in the recovery of 13 654 grams of silver, 5988 kilograms of lead and 1700 kilograms of zinc.

The claim was Crown granted to The Laurier M. & M. Co. in 1899. Owner of the property in 1949 was E. Emilson. The last record of work was in 1951.

In 1971, Hi-Lode Minerals Ltd. completed an 8.5 line-kilometre ground magnetic and electromagnetic survey on the area as the Laurier, Tam-Rak, RFG and Attended Crown-granted claims.

During 2007 through 2011, Goldcliff Resource Corp. completed programs of prospecting, geological mapping, geochemical (rock, silt and soil) sampling and an airborne geophysical survey on the regionally extensive Ainsworth Silver property.

In 2015, Goldcliff Resource Corp. conducted a program of prospecting, geological mapping, geochemical (rock, silt and soil) sampling and a 4.1 line-kilometre ground electromagnetic survey on the area as part of the Ainsworth Silver property.

In 2020 and 2021, Goldcliff Resource Corp. conducted a further program of geochemical (rock, silt and soil) sampling and a 508.0 line-kilometre airborne magnetic, electromagnetic and radiometric survey on the Ainsworth Silver property.
