- Osisko (OSK) confirms new high-grade zone at Golden Bear
- New results include 51.1 g/t Au over 2.0 metres
- The drill program at Golden Bear is currently focusing on the up and down plunge areas of the new D4 zone
- D4 is located 250 metres south-west of D1, is open in all directions
- Mineralization at D4 is hosted in altered felsic quartz porphyry dikes and occurs most commonly as grey to translucent silica replacement
- Osisko Mining Inc. (OSK) is down 2.32 per cent, trading at C$4.21 at 12:46 pm EST
Osisko Mining (OSK) has expanded the Golden Bear discovery.
The Golden Bear discovery is located in the Abitibi greenstone belt, Urban township, Eeyou Istchee James Bay, Québec.
Expansion drilling 250 metres southwest of the Golden Bear discovery hole has defined the presence of a fourth mineralized zone (D4).
This new zone displays silica alteration, pyrite mineralization and local visible gold, similar to the mineralization style observed at the high-grade Lynx zones at Windfall.
D4 is located 225 (metres vertical) below the surface remains open along strike, up and down plunge and has a sub-parallel orientation to the three previously defined “D” zones.
Osisko Mining Chief Executive Officer John Burzynski commented: “The Golden Bear discovery continues to expand with mineralization and alteration typical of what we see at Windfall.”
“Apart from the D Zones, there are also a number of results that do not yet correlate to a defined zone. The team is excited to be working on what we hope will become a significant discovery,” added Burzynski.
The drill program at Golden Bear is currently focusing on the up and down plunge areas of the new D4 zone.
D4 is located 250 metres southwest of D1, is open in all directions and is currently defined by five intercepts.
Mineralization in D1 and D2 is hosted in altered felsic quartz porphyry dike and andesite, and it occurs as pyrrhotite replacement in grey to translucent silica and quartz-carbonate-pyrrhotite veins.
Replacement mineralization is associated with silica alteration and contains trace to 15 per cent disseminated and clustered pyrrhotite with local visible gold and traces of sphalerite-chalcopyrite-galena.
Vein-type mineralization is associated with a halo of pervasive sericite-chlorite ± ankerite alteration containing sulphides (predominantly pyrrhotite with local traces of sphalerite, chalcopyrite, pyrite, galena and arsenopyrite), and local visible gold.
Mineralization at D3 is hosted in altered andesite associated with silica alteration and a halo of pervasive sericite-ankerite alteration, similar to D1 and D2.
Mineralization within the silica alteration consists of trace to 10 per cent pyrite ± pyrrhotite stringers with local visible gold and traces of sphalerite.
Quartz-carbonate vein-type mineralization is also present and consists of trace to 5 per cent pyrite-pyrrhotite and trace amounts of sphalerite. Mineralization at D4 is hosted in altered felsic quartz porphyry dikes and occurs most commonly as grey to translucent silica replacement and veins.
Both types of mineralization are associated with strong pervasive silica alteration with a halo of sericite-ankerite alteration and consist of trace to 20 per cent disseminated pyrite with minor sphalerite and local visible gold.
Mineralization in all zones occurs at or near geological contacts between felsic quartz porphyry dikes and andesites.
