The Osilinka 6 occurrence is located about 760 metres north of the Osilinka River approximately 42 kilometres north of the community of Germansen Landing.

Rocks underlying the occurrence include Ordovician to Lower Devonian Echo Lake Group carbonates. Mapping and prospecting by Cominco Ltd. in 1993 revealed a few localized mineral showings that occur in dolomites. The showings include one or more of the following minerals: galena, smithsonite, hydrozincite and sphalerite. All showings exhibit similar styles of mineralization, occurring as small irregular patches and disseminations in association with dolospar veining or pervasive dolomite flooding. In 1993, a rock chip sample (M92-R96) across 4.0 metres at the Osilinka 6 showing assayed 1.94 per cent lead, 5.44 per cent zinc and 30.9 grams per tonne silver (Assessment Report 23095, Plate 1).

In 1990, Cominco Ltd. staked the Par 1-7 claims following discovery of soils anomalous in lead, zinc, silver and iron over an area of 3.5 by 4.5 kilometres. The Osilinka 6 mineral claim is part of the large contiguous claim group which collectively make up Cominco Ltd.’s 100% owned Par property. The soil anomaly is underlain by a north-northwest trending package of Lower Cambrian to Middle Devonian carbonates and clastics. In 1991, the remainder of the Par property claims were staked to cover extensions of the prospective stratigraphy. Exploration programs in 1990 and 1991 involved: grid soil sampling, geological mapping, airborne and ground geophysics and trenching. Results from the geochemical and geophysical surveys collectively defined a northerly trending zone deemed prospective for hosting lead-zinc mineralization. In 1992, a diamond drilling program was carried out in the vicinity of trenches and along the zone of coincident geophysical (electromagnetic) and geochemical (lead, zinc, silver, iron) anomalies. In addition to diamond drilling in 1992, soil surveys were conducted over other portions of the claim group, including the Osilinka 6 claim, where an extensive, high magnitude lead plus zinc soil anomaly was discovered. In 1993, an exploration program on the Osilinka 6 claim involved geological mapping, line cutting (19.5 kilometres), road (2.0 kilometres) and drill pad (4) construction, ground geophysics (horizontal loop electromagnetic (HLEM, 16.8 kilometres), induced polarization (IP, 7.2 kilometres), and diamond drilling (4 holes, 313 metres). Drill targets were defined by coincident high lead plus zinc soil geochemistry, EM conductivity, and IP chargeability plus resistivity anomalies. Two of the four drillholes were abandoned at shallow depths due to poor ground conditions; the other two holes successfully tested their respective targets. No lead or zinc mineralization was intersected in any of the drillholes. The highest geochemical values returned from drill core were 868 parts per million (ppm) lead, 643 ppm zinc, 3.0 ppm silver, and 1831 ppm barium (Assessment Report 23095).
