The Lucky Coon occurrence is located on the eastern slopes of Spillman Creek, approximately 7 kilometres east of Adams Lake.

The area is underlain by the Lower Cambrian part of the Eagle Bay Formation consisting of siliceous and graphitic phyllites, phyllitic limestone and greenschist. The metavolcanics and meta- sediments generally strike northeast and dip 10 to 40 degrees northwest. The rocks are cut by Late Cretaceous or Early Tertiary quartz- feldspar porphyry and mafic dikes with northerly trends.

Mineralization comprises sulphides of silver, lead and zinc within metasedimentary rocks on the north limb of the Nitwikwaia synform. The showings occur within a dominantly metasedimentary succession (EBGs) of siliceous and/or graphitic phyllite, calcareous phyllite, streaky banded calc-silicate rock, limestone and quartzite. The metasediments are stratigraphically underlain by chloritic schists and greenstone (EBG). (Preto, et al).

The mineralization occurs as layers, lenses and pods of semi-massive to massive sulphides, generally within a siliceous gangue. The sulphide horizons are generally well banded and conformable to the schistosity and where observed, to the bedding. Intense deformation of the rocks has caused discontinuity and marked variability in the widths of the sulphide horizons which tend to thicken in the hinge zones of folds.

The Lucky Coon deposit is exposed intermittently over a strike length of 1200 metres in a northeast trend. Banded and massive sulphides include arsenopyrite, pyrite, sphalerite, galena, argentite, chalcopyrite and minor tetrahedrite within silicified limy phyllites, quartz-sericite schist and greenstone schist. Mineralization widths are generally less than 0.5 metres but may occur up to 2 metres. A 30 centimetre sample gave 0.7 gram per tonne gold, 583 grams per tonne silver, 14.5 per cent lead and 24 per cent zinc.

The Elsie deposit (082M 213) is thought to be a continuation of the Lucky Coon deposit however, it does not appear to be on the same stratigraphic level. Inferred reserves have been noted as 68,033 tonnes of 'high-grade' ore (Canadian Mines Handbook 1972-1973, p. 136 (Giant Metallics Mines Ltd.)).

In 1989, Sirius Resources completed a drill program of 17 diamond drill holes, totalling 1109.4 metres. The best intersections were encountered in DDH 19, which returned values of 271.9 grams per tonne silver, 14.2 per cent lead and 8.6 per cent over 1.65 metres (Property File: Ashton, J.M. (1989-01-24).
