BISON GOLD RESOURCES INC. CENTRAL MANITOBA PROPERTY UPDATE: DRILLING ON OGAMA-ROCKLAND TREND CONFIRM THREE ADDITIONAL GOLD-BEARING STRUCTURES TO THE OGAMA ZONE
Bison Gold Resources Inc. has provided an update on results from drilling on the Ogama-Rockland trend from the company's central Manitoba property.
Three new additional gold-bearing structures parallel to the Ogama zone have now been confirmed through diamond drilling. They have been termed by the company: HW1, HW2 and HW3, and they are approximately 50 metres, 200 metres and 300 metres northeast of the Ogama zone, respectively. The drill holes reported here were drilled in a fence approximately 50 metres along strike to the southeast of drill holes OG-11-09 and OG-11-08 (see press release dated May 30, 2011), with intersections that include: 3.82 metres of 96.5 grams per tonne gold (Ogama zone) and 2.30 metres of 15.6 g/t Au (HW2) from OG-11-09, and 1.91 metres of 206.0 g/t Au from OG-11-08 (HW3). This new interpretation is based upon drill results from six holes and follow-up surface investigations. Intersections from holes OG-11-10, OG-11-11 and OG-11-12 are in the table, "Drill results." The widths reported are drill-intercepted core widths and not true widths. Estimated true widths range from 70 per cent to 90 per cent of core widths. OG-11-13, the fourth hole of this fence of drilling, has been completed and the company is currently awaiting assay results. OG-11-14 is currently being drilled with a target of the Ogama zone 50 metres beneath the intersection of 3.82 metres of 96.5 g/t Au in hole OG-11-09.

"We are very pleased with the results of this drilling program to date. We have not only intersected high grades and widths from the Ogama zone at depth and along strike from the old mine workings, but we have now identified three new gold-bearing structures, which have become legitimate targets for our exploration efforts on the property," stated Lucas Ewart, president and chief executive officer for Bison Gold. As well, Bison plans to drill test at depth below the Ogama zone intersection from OG-10-05 which cut 5.3 g/t Au over 25.64 metres and drill test a previously untested, near-surface, multiline gold-in-soil mobile metal ion anomaly approximately 250 metres along strike to the northwest of the Ogama mine workings.
Surface exploration update
Bison mobilized field crews to the central Manitoba property in late May, and the crews have been conducting extensive investigations of the Eldorado zone, Ogama West, and the surface projections of the HW1, HW2 and HW3 zones. The program consists of extensive grab, chip and channel sampling, lithological and structural mapping, and prospecting. To date, Bison crews have identified the main Eldorado zone at surface and followed it for a strike length of 185 metres; identified an additional gold-bearing structure approximately one kilometre to the northeast of the Eldorado zone (Eldorado east); identified intense alteration, structure and mineralization in the vicinity of the multiline, gold-in-soil MMI anomaly (drill target for this program); and identified the surficial expressions of the HW1, HW2 and HW3 zones. Initial highlights are in the table "Surface exploration highlights."

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 atomic absorption 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 the core processing facility. All rock samples from surface exploration follow the same rigorous protocols. A representative sample for each sample sent for assay is collected in the field and stored at Bison's core processing facility.
All exploration activities for Bison Gold are under the supervision and guidance of David C. Benson, PGeo, a qualified person under National Instrument 43-101. Mr. Benson has reviewed the technical portions of this news release.
