The Nor Occurrence is plotted at approximately 1370 metres elevation on a northeast-facing slope, south of Lendrum Creek and approximately 5.0 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.

Locally, a zone containing lead, zinc and silver is reported. The underlying rocks may be slate, argillite or limestone of the Upper Mississippian to Lower Permian Milford Group.

Work History

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.

The occurrence is reported to have been discovered in 1972. A sample yielded 1.78 per cent lead, 5.70 per cent zinc and 871 grams per tonne silver.

In 1983, 5 tonnes of ore is reported to have been shipped from the occurrence with an average grade of 1.4 grams per tonne gold, 1941 grams per tonne silver, 0.1 per cent lead and 5 per cent zinc (Assessment Report 12572).

In 1984, Michael Linn conducted a program of prospecting and soil sampling on the area as the Prince claim group. In 1987 and 1988, La Ronge Resources Ltd. conducted programs of geological mapping, geochemical (rock, silt and soil) sampling and a 9.8 line-kilometre ground magnetic survey on the area as the Golden group 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 and 2014, 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 southeast as a part of the Ainsworth 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. In 2023, a 92.0 line-kilometre airborne magnetic survey was conducted on the area by Shane Smith.
