Bison Drills into High Grade Gold in Bisset Camp
September 14, 2006 - Toronto, Ontario, - Bison Gold Exploration Inc. (BGEI - CNQ) (“Bison”) announces initial results of core drilling on the Company's 100% owned CENTRAL MANITOBA gold project located in the Bissett Gold Camp in south-eastern Manitoba.
The primary objective of this short program was to test the grade and width of mineralization along the CENTRAL MANITOBA mine structure in the area of the un-mined Wentworth vein, situated between the Kitchener/Growler mines to the west, and the Tene/Hope/Roger mines to the east. See figure below. The CENTRAL MANITOBA mine structure extends for approximately 3 km, but was only mined (1927-1938) where high-grade gold values were present in discrete quartz veins. Mineralization at the CENTRAL MANITOBA property occurs along a gabbro sill in a geologic environment which shows strong similarities to the nearby and recently re-opened SAN GOLD mine in the Bissett Gold Camp.
The scope of this initial program included nine shallow holes into the Wentworth vein and one deep hole in close proximity, reaching under the Tene mine. Drill holes CM-06-1, -2 and -3 were drilled at -45°, -66° and -78° under a series of trenches on the Wentworth vein. Holes CM-06-4, -5 and -6 were drilled at the same orientations from a point 40m along strike to the east, and holes CM-06-7, -8 and -9 were drilled at the same orientations, 40m to the west. The core lengths are the actual lengths as drilled and have not been adjusted for the true width of the mineralized zone.
All drill holes intersected the CENTRAL MANITOBA shear zone, with varying quartz veining and Gold mineralization. The majority of these holes intersected an upper and lower quartz vein with 1 to 2 metres of sheared wallrock in between. Holes CM-06-4, -5 and -6 appear to be cutting the eastern fringe of the vein, with higher grades trending towards the west. Shear zones in the footwall of holes CM-06-5 & -6 including a narrow intersection of 2.12% Cu in the footwall of hole CM-06-5 may mark the start of the next en-echelon vein to the east along the CENTRAL MANITOBA shear. Holes CM-06-1, -7 and -8 intersected high grade Gold mineralization of 9 to 17 Au g/t over narrow widths, and modest gold grades over good widths, typified by CM-06-1 with 4.13 Au g/t over 3.83m.

The final hole in this initial core drill program, CM-06-10, was drilled at -63° targeting the gabbro sill host rock at a vertical depth of 200 to 300m under and to the west of the Tene 2 and Tene 6 mine workings. A deep drill hole CM-06-10 was completed to a drill depth of 454m, intersecting the targeted gabbro host rock at 199 to 392m. Several mineralized, quartz-veined shear zones were intersected within the gabbro, and the assay results are expected by 30th September 2006.
Production at the CENTRAL MANITOBA mines did not extend below 200m and very little exploration was done below that depth in the 1930s. Significant tonnages of lower grade mineralization, including copper values not previously recovered may also be present along the shear zone structure between the old mine workings.
"We are pleased with the results from this initial program," said Chris Watkiss, President and CEO of Bison Gold, "especially the new indications of further mineralization at depth in hole CM-06-10. Based upon the results of this initial program, our planning is already underway for a larger and more extensive core drill program, targeting both shallow mineralization between the old mines, and deeper targets down-plunge from the mined zones."

This core drill program was completed under the supervision of W. C. Hood, P.Geo. a Qualified Person under NI 43-101. Drill core was sawed, with half sent to Accurassay Laboratories in Thunder Bay for analysis. Gold analysis was done with a 50g Fire Assay with AA finish. Check analyses using the Screen Metallics technique will be completed at the end of the program. Copper analyses were done by ICP with Aqua-Regia digestion. Duplicate analyses were completed on every tenth sample and blank samples were also utilized. W. C. Hood has reviewed this News Release.
