The Osilinka occurrence is located at an elevation of approximately 1085 metres on a southwest-facing slope, north of the Omineca River and approximately 6.5 kilometres northwest of Old Hogem.
Regionally, the area is underlain by argillite, greywacke, wacke and conglomerate turbidites of the Upper Triassic to Lower Jurassic Takla Group, which have been intruded by quartz monzonitic to monzogranitic intrusive rocks of the Lower Jurassic Hogem Plutonic Suite. To the southwest and west of the Pinchi Fault mudstone, siltstone and fine clastic sedimentary rocks of the Lower Permian to Upper Jurassic Cache Creek Complex are exposed.
Locally, as defined by diamond drilling, a medium-grained equigranular monzonite with local chlorite-potassium feldspar ± silica alteration with trace finely disseminated chalcopyrite.
In 2009, drillhole OS-09-05 yielded 0.21 and 1.88 grams per tonne gold over 18.0 and 2.0 metres (9.0 to 27.0 and 143.0 to 145.0 metres down hole), respectively, whereas another drillhole (OS-09-02), located approximately 500 metres to the northwest of the previous drillhole yielded 0.10 gram per tonne gold over 22.8 metres (158.0 to 180.8 metres down hole; Assessment Report 31694).
In 2013, a rock sample (R1965166) from an outcrop of pyroxenite with trace chalcopyrite and malachite staining, located down slope of the area previously drilled, assayed 0.133 per cent copper and 0.075 gram per tonne gold (Assessment Report 34271).
Work History
In 2006, Serengeti Resources Inc. staked the area as the Osilinka 1-44 claims. In 2007 and 2008, Serengeti completed programs of geochemical (rock, soil and silt) sampling, a 1249.0 line-kilometres airborne geophysical survey and a 31.3 line-kilometre induced polarization survey on the property.
In 2009, Serengeti Resources Ltd. completed a program of soil sampling, a 17.0 line-kilometre induced polarization survey and six diamond drillholes, totalling 1253.0 metres, on the Osilinka property.
In 2013, Serengeti Resources Inc. completed a program of geological mapping and rock, silt and soil sampling on the property.
In 2014 and 2015, Serengeti Resources Inc. completed a geophysical review of previous airborne and induced polarization surveys.
