Interestingly, roscoelite also occurs in association with telluride minerals at Cripple Creek, Colorado.
Extensions of known ore bodies - all of the currently known mineralised zones, viz: Western Roscoelite Zone, Central Zone, C9 Zone, Black Zone and the Pump Creek Zone have the potential to be extended by detailed drilling both along strike and down dip.
The Company's focus is on drilling three bonanza style targets, with drilling currently continuing at the Western Roscoelite Zone (WRZ).
Roscoelite is confined to deeper deposits; orthoclase, carbonates, fluorite, galena, pyrite, sphalerite, specular hematite, tellurides, quartz, and marcasite occur over the whole range of depths that have been studied.
The two bonanza zones identified along a major fault zone in the Western Roscoelite Zone (WRZ) are currently the focus of drilling and have the potential to host a more substantial bonanza zone.
As part of Buffalo's pre-feasibility work, an in-fill drill program on the Western Roscoelite Zone will begin in mid-February.
Four close-spaced drill holes have been completed to define the extent of the quartz roscoelite bonanza gold zone within the BZ Zone at Mt Kare, around drillhole 122SD11.
Associated minerals are: pascoite, sherwoodite, selenium, bariandite, devilline, rossite, hewettite, carnotite, clausthalite, coffinite, tyuyamunite, uraninite, corvusite, montroseite, roscoelite, galena, pyrite and tennantite.
A drill program commenced in December to define the extent of bonanza grade Quartz Roscoelite mineralisation encountered in the BZ Zone around drillhole 122SD11.
Associated minerals are: dolomite, quartz, roscoelite, chromphyllite, calcite, hematite, uraninite, zincochromite, vanadium oxides, etc.
A two part drilling program is aimed to test quartz roscoelite mineralisation which is associated with bonanza gold grades.
Massive pyrrhotite occurs intimately associated with the arborescent electrum and roscoelite, and as small blebs and streaks in clasts of the sedimentary host rocks within the quartz/calcite veins.
