The Redfern (Southface) occurrence is located on a south-facing slope, approximately 2.8 kilometres northeast of the southeast end of Redfern Lake.

Regionally, the Redfern Lake area is underlain by Middle Devonian Dunedin Formation carbonates conformably overlying Lower to Middle Devonian Stone Formation dolomites. To the east, this package is thrust over Devonian to Carboniferous Besa River Formation shales. To the west, a package of Cambrian to Ordovician Kechika Group, Ordovician Skoki Formation, Silurian Nonda Formation, Lower Devonian Muncho-McConnell Formation and Lower to Middle Devonian Stone Formation rocks are thrust over the Dunedin Formation. The Dunedin Formation can be divided into two units: a lower dolomite unit and an upper limestone unit.

The Southface occurrence is hosted within fossiliferous-granular dolomite of the lower Dunedin Formation near the contact with the upper limestone unit. Mineralization consists of two stratiform zones of disseminated sphalerite and galena with associated drusy quartz and calcite patches. The zones, separated by 3 metres of barren strata, vary from 0.5 to 2 metres in width and can be traced for 2000 metres.

In 1975, a grab sample from the southern end graded 7.8 per cent zinc and 0.14 per cent lead; 700 metres to the west a second sample returned 1.8 per cent zinc and 0.04 per cent lead (Assessment Report 5551). A 3- by 1-metre lens of massive limonite, sphalerite, smithsonite, galena and minor pyrite occurs within the upper zone from which a grab sample graded 44.0 per cent zinc and 14.6 per cent lead (Assessment Report 5551).

In 1979, chip sampling, approximately 1.4 kilometres northwest of the plotted location of the Southface occurrence, yielded up to 3.50 per cent zinc and 3.45 per cent lead over 1 metre in sample 37.5W, whereas another sample (70W) yielded 20.9 grams per tonne silver over 2.5 metres (Assessment Report 7705).

Work History

In 1972, Vestor Explorations Ltd. completed a program of geological mapping and soil sampling on the Redfern Lake area as the Chilly, Damn, Egg and Foo claims. In 1973, Rio Tinto Exploration Canada Inc. completed a program of geological mapping, minor rock sampling, a 36.2 line-kilometre induced polarization survey, a 30.5 line-kilometre ground magnetic survey and a photogeological study on the Foo, Egg, Chilly, Vista and Damn claim groups. In 1974, Rio Tinto Canadian Exploration Ltd. completed nine diamond drill holes, totalling 608.0 metres, on the Vestor property. The following year, a further program of geological mapping and soil sampling was completed on the property. In 1979, Teck Explorations Ltd. completed a program of geological mapping and geochemical (rock and soil) sampling on the Vestor property.
