Capsule Geology

The Sam occurrence is located 38 kilometers west of the community of Burns Lake, 900 metres northeast of Goosly lake.

The Sam property is within the northern part of the Nechako Trough which hosts strata consisting of a sequence of Mesozoic volcanic and sedimentary rocks overlain by an extensive sequence of Tertiary volcanics.

Along the north side of Goosly Lake, the area is underlain by Cretaceous to Tertiary Francois Lake Group rocks, mainly Upper Cretaceous Tip Top Hill Formation volcanics which are overlain by Eocene Goosly Lake Formation. The Tip Top Hill Formation is comprised mainly of andesite, andesitic to dacitic lavas and pyro- clastics which are overlain by feldspathic andesite, trachyandesite lavas, breccias, sills and stocks of the Goosly Lake Formation (Bulletin 78, Figure 1).

Most of the rocks have undergone sericite-carbonate-chlorite and quartz alteration. Grey clay is found locally along fracture and pyrite is disseminated throughout. Massive sulphide veins, ranging from 0.1 to 3.0 metres in width, occur along the southeast side of the altered belt of andesitic tuffs and volcanic breccias. The dominant sulphide in these veins is pyrite with minor sphalerite and traces of chalcopyrite, tetrahedrite and arsenopyrite. The alteration zone strikes about 120 degrees, dips steeply north and ranges from 70 to 200 metres in widths.

Majority of the massive to semi-massive sulphides were located within the East zone, at depths of 20 to 230 metres. Four small, mineralized intervals were intersected in the West zone, located 500 metres northwest of the East zone. The rocks between these zones (the Central zone) are altered, but no significant mineralization was found.

Drilling in 1986 and 1987 in the East zone within the pyritic calcite-quartz-silicate alteration zone intersected several massive to semi-massive sulphide intervals with silver values ranging from 25.0 to 715.0 grams per tonne values usually less than 1 per cent with high values up to 9.5 per cent zinc (Assessment Report 17307). The sulphide intervals were often brecciated, and locally clay is a matrix.

Work History

In the late 1960’s and early 1970’s the Sam claims were part of a larger block of claims, including the Donna and Paula claims to the south, controlled by Silver Standard Mines Limited.

In 2009, a program of rock sampling and a 1.6 line-kilometre induced polarization survey was completed on the area as the Gillian Silver property.

In 2017, Copper Mountain Mining Corp. completed a 40 line-kilometre airborne electromagnetic (ZTEM) survey on the area as the Goose 1 property. In 2020, Prosperity Exploration Corp. completed a 170 line-kilometre airborne electromagnetic (VTEM) survey on the area as the Silver Lake property.
