TORONTO, ONTARIO--(Marketwire - Feb. 23, 2011) - Bison Gold Resources Inc. ("Bison Gold" or the "Company") (News - Market indicators) is pleased to announce 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 g/t Au 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 tabulated below. The widths reported are drill intercepted core widths and not true widths.

"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 P.Geo, V.P. 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. 

QA/QC

Drill core was sawed, with half sent to TSL Labs in Saskatoon, SK and the other half retained for reference. Most gold analyses were done using 50g fire assay with AA finish. A gravimetric finish is employed where samples return gold values in excess of 3000 ppb. 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 in to the sample series at their core processing facility. 

All exploration activities for Bison Gold are under the supervision and guidance of David C. Benson, P.Geo, and a Qualified Person under NI 43-101. Mr. Benson has reviewed the technical portions of this news release.
