Expedition Acquires Second Gold Property in the Yukon's Rackla Gold Belt Near ATAC

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 12, 2011) -

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Expedition Mining Inc. (TSX VENTURE:EXU) (the "Company") is pleased to announce it has entered into an option agreement pursuant to which it can acquire a 100-per-cent interest in the Mt. Mervyn gold property from Paul Dadwal. The Mt. Mervyn property is located in the Mayo Mining District of central Yukon, 5 kms from ATAC Resources' Rau Gold Property, where Carlin-type gold mineralization has been discovered, and adjacent to Strategic Metals' claim block.

Ron Atlas, president and chairman, said: "We are very excited about the acquisition of the Mt. Mervyn gold prospect. This property, along with our Joy property, gives us a great land position in the newly emerging Rackla Gold Belt. With our recent financing of $2.2 million, we are committed to aggressive exploration on all our Yukon properties this year and will be announcing extensive work programs in the very near future."

The Mt. Mervyn property is comprised of 314 unpatented mining claims, approximately 6,564 hectares (65.64 sq kilometres), located in the recently defined Rackla Gold Belt. This is an early stage exploration project, with numerous defined similarities to ATAC Resources' Nadaleen Trend that hosts Carlin-type gold mineralization.

Initial data review by the owner indicates the claim block covers calcareous rocks of the Hyland Group, which is the same formation that hosts gold mineralization on the ATAC claim block. Also present on the property are numerous fault structures which are similar to the structural setting on the nearby ATAC properties.

Gold mineralization potential was originally defined by earlier mapping and sampling completed by the Geological Survey of Canada and more recently by the Yukon Geological Survey. This work recognized gossans and sulphide mineralization on the claim block which appears to be associated with younger intrusive dikes.

The Mt. Mervyn property has excellent potential for hosting gold mineralization in a similar setting to ATAC's nearby prospects.
