BISON GOLD RESOURCES INC. CENTRAL MANITOBA PROPERTY UPDATE: HIGH GRADE GOLD INTERSECTIONS FROM DIAMOND DRILLING ON OGAMA-ROCKLAND TREND CONFIRM DEPTH EXTENSION OF THE OGAMA ZONE
Bison Gold Resources Inc. has released further results from drilling on the Ogama-Rockland trend on the company's central Manitoba property.
Diamond drill hole OG-10-05 intersected the Ogama structure approximately 50 metres below the OG-09-07 drill hole intercept of 35.0 grams per tonne gold over 4.73 metres. OG-10-05 intersected 17.6 g/t Au over 6.55 metres within a 25.64-metre intercept that returned assays of 5.3 g/t Au. Additionally, drill hole OG-10-05 intersected a new gold-bearing structure in the hangingwall to the Ogama zone: 1.46 metres of 16.6 g/t Au. Significant results are in the attached table. The widths reported are drill intercepted core widths and not true widths.
DRILL HIGHLIGHTS Drill hole Core interval (m) Width (m) Au g/t OG-10-05 485.36-511.00 25.64 5.3 including 489.86-496.41 6.55 17.6 including 489.86-491.63 1.77 50.8 including 493.34-496.41 3.07 8.2 including 501.08-504.71 3.63 4.5 OG-10-05 158.29-159.75 1.46 16.6
"The results from OG-10-05 are very significant in the fact that not only high-grade gold mineralization persists at depth but the gold-bearing structure (the Ogama zone) appears to be increasing in thickness with depth," stated David Benson, PGeo, vice-president of exploration for Bison Gold. Bison's current drilling program has evolved with the OG-10-04 and OG-10-05 high-grade gold intersections and will continue to drill test depth and strike extensions of the Ogama zone away from the historical mine workings.
Quality assurance/quality control
Drill core was sawed, with half sent to TSL Labs in Saskatoon, Sask., and the other half retained for reference. Most gold analyses were done using 50-gram fire assay with AA finish. A gravimetric finish is employed where samples return gold values in excess of 3,000 parts per billion. Screen metallics techniques were used on samples with visible gold. TSL maintains a strict quality control program with standards, blanks and duplicates included with every sample series. Standards and blanks are inserted regularly by Bison Gold personnel into the sample series at its core processing facility.
All exploration activities for Bison Gold are under the supervision and guidance of Mr. Benson, PGeo, and a qualified person under NI 43-101. Mr. Benson has reviewed the technical portions of this news release.
We seek Safe Harbor.
