TORONTO, ONTARIO--(Marketwire -01/09/12)- Bison Gold Resources Inc. ("Bison Gold" or the "Company") (TSX-V: BGE.V - News) is pleased to announce the commencement of a 15,000 metre diamond drilling program on the Central Manitoba Property. The drilling program will focus on an identified high grade corridor in the immediate vicinity of the past-producing Ogama Mine as well as evaluating the potential that the Property could host Osisko Mining Corp. (TSX: OSK.TO - News) "Hammond Reef" bulk tonnage gold mineralization. Results from the past years diamond drilling have been compiled with the past two years worth of surface exploration (geological mapping, lithogeochemical sampling, channel and trench sampling). Interpretation of the results indicates that the Ogama zone and the new HW Zones occur within a much larger gold-mineralized structural corridor. This drilling campaign will, in part, attempt to outline the limits of this corridor as well as define the high grade 'core' centred in the vicinity of the Ogama mine.

Over the past two years, Bison has collected and analyzed 8,417 drill core samples from 32 diamond drill holes and 1,733 grab, chip and channel samples from the Project area. The following tables re-state the highlights from the past two years drilling and surface exploration.

Table 1. Drill Intersect Highlights from Bison's Drilling 2009-2011. Refer to press releases dated July 7 and August 17, 2010; and February 11, February 24, May 30, July 8, August 24 and December 15, 2011.

"The results speak for themselves. Numerous and impressive high-grade gold mineralization is being discovered at less than 500 meters depth at the former past producing Ogama Mine site. These results are comparable to some of the best gold discoveries made in Rice Lake, Manitoba at similar grade, width and depth." said Lucas Ewart, President and CEO of Bison Gold, referring to neighboring Gold producer, San Gold Corp. (TSX: SGR.TO - News).

The Ogama Mine was nearly written off years ago after the initial exploration program conducted in Central Manitoba was focused almost entirely on the more eastwardly past producing Central Manitoba mineshafts. Only 3 holes, were drilled to a depth of 400 meters at the Ogama Mine, it was on the last hole a bonanza strike of 35 g/t over 4.73 meters was initially discovered.

"35 g/t over 4.73 meters, took a lot of people by surprise. The discovery was made only 90 meters below where the historical Ogama Mine workings had ended." said Amir Mousavi, Bison Gold's VP Corporate Development and Chief Financial Officer. "The Ogama mine produced 40,000 oz Au between 1925-1940, 1948-1951 and at higher head grades (12 g/t Au) than that of the more prominent San Antonio Mine (10 g/t Au) at the time". The San Antonio mine produced 1.2 million oz Au between 1925-1940 at grades of 10 g/t Au. Today, the San Antonio mine is better known as the San Gold Corp (TSX: SGR.TO - News) Rice Lake Gold Mines, an evolving gold producer located only 26 km north/west of Bison Gold's Rice Lake Central Manitoba Property claims, connected by an all weather provincial road.

Bison Gold's Rice Lake property includes 8 past producing mines and mine shafts that were optioned to Placer Dome in 2003. Placer Dome had a corporate mandate to discover a minimum 10 g/t Au over 3 meters, which failed to be achieved after a short drilling program in 2004. "Exploring for gold in Manitoba requires experience, patience, ambition and a lot of luck, something Bison Gold's exploration team has no shortage of," said Mr. Mousavi. "Placer Dome's decision to drop the program inevitably changed the future of Rice Lake. They were only a few short meters away from discovering bonanza Gold grades. Had they discovered what we are today, Rice Lake would have looked more like Red Lake and home to some world-class gold producers."

The Rice Lake mining camp lies approximately 100 km west of Red Lake's mining camp. Both mining camps are within the Uchi Subprovince of the Canadian Shield, a geologic terrane that spans beyond the two distinct gold mining camps and hosts numerous precious and base metal deposits.

"The style and structural pattern of the Gold mineralization on Bison's Property is very similar to that of the San Gold's Main Mine and newly discovered deposits," said Scott Snider, Bison's Exploration Manager. Mr. Snider worked as an Exploration Geologist for San Gold prior to coming to Bison.

Nearby San Gold Corp. (TSX: SGR.TO - News) recently published Gold assays of comparable grade, width and at similar depth as those discovered during Bison Gold's 2010-2011 drilling program (refer to SGR News Release on December 20, 2011). Albeit there is no certainty further exploration will define a gold deposit of the size and grade of the San Gold deposits.

The figure below is a comparison between San Gold's published results from December 20, 2011 and the re-stated drilling results from Bison's 2009-2011 drilling program.

"We are very pleased for our neighbors " said Mr. Ewart, referring to San Gold's recent news release. "The Rice Lake belt remains one of Canada's best kept secrets, and San Gold has done a excellent job of achieving several milestones in the last year that is finally bringing recognition to the belt".
