The Gillman occurrence is located on the north side of the east fork of Mohawk Creek, a north-flowing tributary of Pool Creek, at an elevation of approximately 1800 metres.
The area is underlain by metasedimentary rocks of the Lower Paleozoic Lardeau Group, which includes medium-grey to greenish quartzites, greywackes, carbonaceous phyllites and quartz sericite schist.
Locally, a north to northwest-striking, east-dipping quartz vein, 0.6 to 2.0 metres wide, cuts shale and phyllite. The vein contains galena, pyrite and sphalerite and has been followed along strike for 60 metres.
In 1914, a sample assayed 109 grams per tonne silver and 124 grams per tonne gold (Annual Report 1914, page 263).
In 1933, a 1 tonne sample of ore returned 62 grams of silver, 62 grams of gold, 22 kilograms of lead and 23 kilograms of zinc.
In 1979, sampling averaged from 3.4 to 6.8 grams per tonne gold, with values in excess of 17.1 grams per tonne gold coming from irregular pods and lenses of pyrite (Property File - J. Jenks [1979-01-01]: Property Report - Placid Oil Company - The Bob Leighton Mining Interests in the Trout Lake Area).
In 1988, diamond drilling was reported to have yielded up to 10.2 grams per tonne gold over 3 metres and 23.9 grams per tonne gold over 4.2 metres (Property File - Bryndon Ventures [1988-03-21]: News Clipping - High hopes for Bryndon). Also at this time, a stockpile of approximately 1814 tonnes of ore averaging greater than 34.2 grams per tonne gold was reported (Property File - Bryndon Ventures [1988-03-21]: News Clipping - High hopes for Bryndon).
In 2014, rock samples from the Gillman occurrence yielded up to 0.13 per cent lead and 8.29 grams per tonne gold (Assessment Report 35310).
In 2016, a grab sample from the Gillman occurrence assayed 57.1 grams per tonne gold, 108 grams per tonne silver, 0.59 per cent zinc, 2.8 per cent lead and 0.11 per cent copper (Chapman, J. (2019-03-20): National Instrument 43-101 Technical Report on the Silver Dollar Property).
Work History
The area has been explored since the late 1800s in conjunction with the nearby Beatrice (MINFILE 082KNW040) and Silver Dollar (MINFILE 082KNW101) occurrences.
