TORONTO, ONTARIO--(Marketwire - May 30, 2011) - Bison Gold Resources Inc. ("Bison Gold" or the "Company") (News - Market indicators) is pleased to provide an update on results from exploration drilling on the Ogama-Rockland trend from the company's Central Manitoba Property which has yielded its highest gold intersections to date.

Highlights include: Diamond drill hole OG-11-09 which intersected 7.96 meters of 46.19 g/t Au in a zone of intense alteration and quartz veining containing visible gold within a granodiorite. This drill hole intersected the Ogama zone approximately 100 metres west of drill hole OG-09-01, which intersected 36 g/t Au over 1.92 metres and 42 metres below OG-09-02, which intersected 25 g/t Au over 0.99 metres. Additionally, drill hole OG-11-09 intersected a new gold-bearing structure in the 'hangingwall' to the Ogama zone; 2.30 metres of 15.56 g/t Au. Drill hole OG-11-08 intersected a previously unrecognized near surface heavily altered structure containing a vein of coarse visible gold associated with fine-grained pyrite. This new zone cut 206.00 g/t Au over 1.91 metres. Significant results are tabulated below. The widths reported are drill intercepted core widths and not true widths.

"Our drilling to date has outlined significant high-grade mineralization at depth below and extending along strike to the old Ogama mine workings as well as intersected multiple additional structures and drill targets in the 'hangingwall wall' to the Ogama structure", stated Lucas Ewart, President and CEO for Bison Gold. Bison is currently drilling a fence of holes approximately 50 m to the east of the intersections from holes OG-11-08 and OG-11-08. Initial results from the holes are anticipated to be released in the coming weeks as there are over 600 prepared core samples still awaiting assay testing. 

"We are exceptionally pleased with the success rate of our drilling targets and with over $3.7 million in the treasury we will continue our active exploration program through the summer and fall of 2011", stated Amir Mousavi, VP Corporate Development for Bison Gold. Over the past 6 months alone Bison Gold has conducted over 7000 meters of drilling making it the most active pure exploration company in the Rice Lake area.

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.
