Expedition Begins Airborne Electromagnetic Survey on Joy and Mt. Mervyn Properties in Rackla Gold Belt

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 10, 2011) - Expedition Mining Inc. (TSX VENTURE:EXU) -


Expedition Mining Inc. (the "Company") is pleased to announce that it has begun an airborne time-domain electromagnetic survey over the Joy and Mt. Mervyn properties. Both the Joy and the Mt. Mervyn properties, consisting of 128 and 314 claims respectively, are located in the Rackla Gold Belt. This newly discovered gold district hosts ATAC Resources' Rau property which contains drill-confirmed "Carlin-type" gold mineralization.

"Carlin-type" gold deposits are defined as economic amounts of gold finely disseminated throughout host rocks of varying composition, originating from hydrothermal processes with a structural control component. The Joy and Mt. Mervyn properties are located between the regional scale east-west trending, Dawson Thrust and the Kathleen Lakes Fault, and within a carbonate inlier of the Selwyn Basin Paleozoic tectonic province. Gold-bearing sulphide and oxide mineralization at the Rau property occurs in shallow water limestone, dolomite, and calcareous siltstone of Cambrian to Devonian age, locally intruded by Triassic granitic plutons and quartz porphyries.

Approximately 1000 line-km of high-resolution magnetic and electromagnetic data will be collected in May 2011 with the SkyTEM system. This airborne survey will identify prospective structures and conductors on the properties and provide a framework for a summer program of geological mapping and sampling. The surface exploration programs are designed to rapidly advance any new discoveries to the drilling stage.

All technical information contained in this release has been reviewed and approved by Bert W. Jeffries, PGeo, a qualified person within the meaning of National Instrument 43-101.
