Orex Announces New Drilling Campaign at Goldboro

MONTREAL, CANADA--(Marketwire - Feb. 8, 2011) - OREX EXPLORATION INC. (TSX VENTURE:OX)(FRANKFURT:O5D) would like to inform shareholders that Osisko Mining Corporation (TSX: OSK; Deutsche Boerse: EWX) has approved a new exploration drilling campaign at Orex's wholly-owned Goldboro Gold Property. Osisko has advised Orex that this drilling campaign will include 10 holes for approximately 2,500 metres of drilling on two areas of the Goldboro Gold Property. The areas to be drilled are, more specifically: 1) a 600-metre interval between West Goldbrook and Dolliver Mountain, where there is no record of previous drilling due to a large bog that limits access; and 2) a 750-metre interval from East Goldbrook to the east property boundary. Osisko is in the process of finalizing the budget for this campaign and negotiating with suppliers, after which it intends to begin drilling at Goldboro in March 2011.

Four diamond drill holes are planned on two sections spaced 200 metres (m) apart in the West GoldBrook – Dolliver Mountain gap where there is no record of previous drilling. At the east end of the gap, 2010 drill hole number OSK10-09 yielded 36.5 m grading 1.07 grams per tonne (g/t) gold (Au) and containing a 10.5 m interval grading 2.15 g/t Au at a vertical depth between 150 m to 200 m below surface. The mineralized zone is projected to extend up-plunge westerly towards surface in the area to be drilled (refer to news release of June 10, 2010).

Six drill holes are planned on 3 sections spaced 250 m apart from East Goldbrook to the east property boundary. In 2010, reverse circulation (RC) drilling was completed along a fence of closely spaced holes (25 to 50 metres apart) across the indicated trend of mineralization in this area. Bedrock chip samples from 6 RC holes yielded grades above 0.1 g/t Au, within a 250 m-wide mineralized corridor extending eastward from East Goldbrook. Three of these RC holes contained bedrock chip samples with grades above 1.0 g/t Au specifically; 1.38, 10.85 and 25.65 g/t Au respectively (refer to news release of November 18, 2010).

Mark Billings, President and CEO of Orex, commented, "The management of Orex is pleased that Osisko will soon begin the next drilling campaign. This campaign will provide us with information on the previously undrilled 600-metre gap between West Goldbrook and Dolliver Mountain. In addition, the RC drilling results of last year demonstrate that gold mineralization extends eastward from East Goldbrook, which we hope to test further with this campaign. The two areas collectively provide nearly 1.5 km of untested strike length."
