The Townsite occurrence is located near the south bank of Munn Creek at an elevation of approximately 760 metres and approximately 500 metres west 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.

In the Townsite adit, a stratabound seam of massive pyrite with minor sphalerite and chalcopyrite is reported.

In 1980, a grid sample (A80-2209) of massive sulphides from the Townsite adit assayed 0.8 per cent copper, 0.1 per cent lead, 0.5 per cent zinc and 112.8 grams per tonne silver (Assessment Report 9347).

Work History

In the late 1800s or early 1900s, the Townsite adit was drifted for 55 metres at 250 degrees, at which point it turns and follows the main Highlander vein for 90 metres. A secondary vein system 25 metres from the portal has been drifted on for approximately 70 metres in a generally south direction.

The property was acquired by Yale lead & Zinc Mines Ltd. in 1949 and was worked, along with the Highlander (MINFILE 082FNE030), Albion (MINFILE 082FNE140) and other claims, up until 1959. It is reported that in 1953, 682 tonnes of ore was milled from the Townsite mine.

In 1979, David Minerals Ltd. conducted a program of geochemical (stream and silt) sampling on the area as the Peanut Butter claims of the Ainsworth property. The following year, Lacana Mining Corp. conducted a program of geological mapping on the Jack Pot claim. In 1990, Dragoon Resources Ltd. conducted a soil sampling program along Munn Creek, immediately west of Ainsworth, as the PB 7 claim.

In 2012, David Wallach prospected and rock sampled the area as the Ainsworth property. In 2019, Bill Mckinney conducted a program of prospecting, rock sampling and aerial photo structural interpretation on the Ainsworth property. In 2021, a 24.0 line-kilometre airborne (drone) magnetic survey was conducted on the area by Taylor Lorenzen. In 2023, Turnagain Resources Inc. conducted a further program of prospecting, rock sampling and aerial photo structural interpretation on the Ainsworth property.
