The Let Her Go Gallagher occurrence is located at approximately 1200 metres elevation on a generally east-facing slope between Cedar and Lendrum creeks, approximately 3.9 kilometres 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.

The property occurs in a thick mass of fine-grained grey and white limestone of the Mississippian to Permian Milford Formation. Production has consisted of high-grade silver ore, mainly from pods of rusty gossan near the surface. One pit exposed a narrow-sheared zone striking 050 degrees and dipping 30 degrees to the north, along which galena and minor chalcopyrite are scattered. One of the dumps contains blocks of vein calcite with clusters of galena and reddish sphalerite.

Work History

The Gallagher property was worked from 1888 to 1890 and again from 1907 to about 1920. A number of shafts and open pits and at least one adit were excavated. An unknown quantity of ore was shipped in 1907 and in the following year approximately 68 tonnes of ore was shipped. In 1914, a crosscut tunnel was extended for approximately 84 metres. The following year approximately 144 metres of drifts, crosscuts and raises were developed, and approximately 11.8 tonnes of ore was shipped. In 1917, a further 28.1 tonnes of ore is reported to have been shipped.

In 1956, Highland-Bell Ltd. conducted a program of geological mapping on the area as the Big Bluff, Fred, Mar and Nick groups of claims.

In 1996, a program of prospecting and geochemical (rock, silt and soil) sampling was conducted by George Addie on the area as the Silver Hoard property.

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 2012, David Wallach prospected and rock sampled the area as the Ainsworth 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 2016, David Wallach conducted a soil sampling program on the area immediately southwest as a part of the Ainsworth property. In 2019, Lee Lorenzen conducted a soil sampling program on the area as the Ainsworth Crown 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. Also in 2021, a 48.0 line-kilometre airborne (drone) magnetic survey was conducted on the area by Taylor Lorenzen. In 2023, a 92.0 line-kilometre airborne magnetic survey was conducted on the area by Shane Smith.
