The Silver Glance occurrence is located near the south bank of Lendrum Creek at an elevation of approximately 930 metres and approximately 4.7 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.
The occurrence area is underlain by schist and limestone of the Mississippian to Permian Milford Formation. Several quartz-bearing fissures are mineralized with galena, sphalerite, pyrite and marcasite.
A tunnel (Silver Glance adit) at creek level follows the vein in a 110-degree direction for 66 metres. Here the vein splits and is followed by two branches of the tunnel, one going 85 degrees for 23 metres, in which the vein appears to pinch out, the other branch extending for 18 metres at 110 degrees with the vein still in the face.
Assays from 1896 are reported to be high in silver and gold. No record of production exists but the Annual Report for 1898 mentions that 163 tonnes was sorted for shipment. In 1955, approximately 4.5 tonnes of sorted ore was obtained from the clean up of the adit and shipped. The following year, 5.4 tonnes of hand-picked ore, grading 789 grams per tonne silver, from a small raise on a fracture zone filled with quartz and/or calcite in a hornblende schist was shipped (PF - Brown, C.J. (1956-07-11): A Report on the Property of Triumph Mines Inc.).
Work History
This group of claims lies along the western edge of the Highland and Florence properties and covers an area extending from near Cedar Creek to the South Fork of Woodbury Creek.
Most of the development work on the Hercules claim was done in approximately 1890. The workings consisted of 36.5 metres of tunnel in two adits, a shaft 4.5 metres feet deep and some trenching. In approximately 1985, a 22.8-metre shaft was put down on the Sullivan claim. Apparently, no work has been done on the Noranda claim.
The Silver Glance claim has had the most development work done on it. The property was located in 1896 and was apparently worked intermittently for approximately 4 years. By 1899, approximately 106.7 metres of underground development had been completed.
The Hercules-Sliver Glance group consists of the Hercules, Sullivan, Noranda, Silver Bell, Glen Ellen, Harrison, Free Silver and Silver Glance claims. Three of the claims, formerly called the Pataha, Ellen and Bugaboo were relocated in 1951 under the respective names of Hercules, Sullivan and Noranda.
In 1951, Nubar Mines Ltd. of Toronto held an option on the claims and are reported to have completed some diamond drilling. In 1952, the Asbestos-Corporation Ltd. completed approximately 914 metres of diamond drilling in 30 holes. The results of this work have apparently not been released by the company. In 1952, Guichon Mine Ltd., owners of the Buckeye claim, held an option on all the above claims; however, their work was apparently confined to the Buckeye.
During 1951 through 1957, considerable work was done on the area by Triumph Mines Limited. The adit was rehabilitated and enlarged in 1955. The following year, the adit was extended to approximately 250 metres from the portal towards the Noranda (MINFILE 082FNE038) workings and is reported to have intersected encouraging concentrations of silver-lead-zinc mineralization in a band of limestone approximately 202 and 217 metres from the portal. In 1957, the adit was advanced a further 63.7 metres for a total of 314 metres. Also 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 1979, the area was held and explored by Ainsworth Resources Ltd. The adit was reported to be approximately 320 metres long by this time.
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.
