Otis Stakes New Matrix Creek Silver-Gold Target at Oakley
Bulk-tonnage silver-gold mineralization crops out in a Black Matrix Breccia ("BMB") within the Matrix Creek detachment fault zone cutting Paleozoic quartzite. Outcropping mineralization is contained within stacked sheets between 5- to 15-metres-thick and is exposed along the ridge of a large synclinal fold over a surface area approximately 200 metres by 350 metres. This mineralization comprises a brecciated structural zone along the northern limb of the fold. Fourteen rock-chips of BMB outcrop collected along the ridge contain significant silver-gold mineralization. The samples contain up to 306 g/t Ag and up to 1.34 g/t Au, with all 14 samples averaging 70.4 g/t Ag and 0.55 g/t Au. The equivalent gold grade of the 14 samples is 1.67 g/t Au. Preliminary 48-hour bottle-roll results performed by ALS Chemex Labs in Vancouver, B.C., suggest that the gold is up to 82% recoverable and that the silver is up to 93% recoverable.
The mineralized detachment containing the BMB is deformed into a southwest-plunging synclinal fold. Otis geologists have recently discovered mineralized BMB cropping out along the southern limb of the synclinal fold that is almost one-mile south of the mineralized ridge described above. The new BMB target has never been drilled.
All assay work was performed by ALS Chemex Labs, Vancouver, B.C., which has ISO 9001:2008 quality management system certification and ISO 17025:2005 technical capability accreditation. A 30-gram pulp of all samples was assayed for gold by Fire Assay/AA finish methods. Silver was analyzed by four-acid digestion.
