Mar 20, 2008 (Mark Puumala) - The Oliver occurrence is described by Atkinson et al. (1990) as consisting of eight separate sulphide showings located at the northern end of Setting Net Lake. The main showing, which is reported to have produced occurrence-grade copper and zinc assays by Cruickshank (1988) and Atkinson et al. (1990) is located approximately 600 m east of the lakeshore. The Oliver occurrences are reported by Atkinson et al. (1990) to include two types of mineralization. The first consists of disseminated and semi-massive sulphides hosted by interflow metasedimentary horizons that occur within mafic metavolcanics. The second occurrence type is hosted within the mafic metavolcanics and consists of disseminated sulphides in variably altered flows. The main Oliver occurrence is described by Atkinson et al. (1990) as a north-northeast-trending unit of sulphide-rich interflow metasediments enclosed by massive mafic metavolcanic flows. The metasedmentary horizon is up to 23 m wide and has been traced over a strike-length of approximately 1.2 km. The Oliver occurrences have been interpreted by Parker (1999) to be examples of volcanogenic sulphide mineralization. Mineralization is reported to consist of pyrrhotite, pyrite, minor chalcopyrite and sphalerite that occurs as thin layers and discontinuous massive pods or lenses. Disseminated sulphides are also reported to occur throughout the host rock (Atkinson et al. 1990). Alteration minerals include large brown-red garnets (up to 3 cm), fibrous green actinolite and epidote. Chalcopyrite concentrations are reported to be highest in the garnetiferous material. Atkinson et al. (1990) report grab sample assay results of up to 3930 ppm Cu and 3150 ppm Zn, while Cruickshank (1988) reported assay values of up to 4220 ppm Cu and 5600 ppm Zn. Atkinson et al. (1990) also report that a sample collected by Minorex assayed 0.7% Cu.
