Expedition Mining Inc.: 2012 Exploration Plans for Joy and Mt. Mervyn Properties

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 31, 2012) - Expedition Mining Inc. (TSX VENTURE:EXU) (the "Company") wishes to announce the receipt of their Class 3 Exploration Permit, and that plans for the 2012 field program on the Joy and Mt. Mervyn Projects have been finalized. Work will commence once weather conditions permit. The properties are located between the Kathleen Lakes Fault and the Dawson Thrust, along the Rackla Gold Belt in the Yukon. The target is Carlin-type gold mineralization similar to that being drilled by ATAC Resources and Strategic Metals on their adjoining properties.

The work program will focus on those portions of the properties that contained multi-element geochemical anomalies, geophysical targets and prospective geology. The geochemical anomalies are believed to be significant as they include the important pathfinder elements of As, Sb, Hg and Tl, which have been associated with gold mineralization at the Rau and Nadaleen trends of ATAC Resources, and the Crag showings of Strategic Metals. The 2012 program will concentrate on gaining a more complete understanding of the geology in the anomalous areas through additional rock sampling, trenching, detail mapping and ground geophysical surveys to define drill targets.

Regional mapping has shown the properties to be underlain by fault bounded slices of limestones, clastic sedimentary units and ultramafic rocks. On the Joy property these units appear to have a southerly dip which is significant as the soil geochemical anomalies occur along the northern edge of the property. Extensive, and locally intense, quartz-carbonate alteration is associated with structural breaks in all of the rock types identified.

Prospecting has resulted in the discovery of two showings associated with the lower contact of the ultramafic unit. These are located in the northwest corner of the Joy property and were named the Virga and Kermoda showings. Silver, lead-zinc mineralization is associated with quartz carbonate veining in these rocks. The showings are also highly anomalous in As, Cd, Hg, Sb and Tl along with elevated gold. Sampling of the ultramafic rocks indicates that they are significantly depleted in all these elements. Rock sampling in the area of the showings has exposed strong mineralization as shown in Table 1.

The mineralization identified to date is associated with extensive, and locally intense, quartz-carbonate alteration zones. These zones show a strong correlation to the east-west trending thrust slices of the Dawson Thrust, particularly in the vicinity of cross-cutting northerly trending structures.

Geological and logistical support for the program is being provided by Aurora Geosciences, who constructed a 15 man camp on the Mt. Mervyn property in 2011.

Mr. James Chapman, P.Geo., is the Qualified Person responsible for the design of the program, and all exploration work on the Joy and Mt. Mervyn Properties will be done under his supervision. Mr. Chapman has read and approved the technical content of this news release.
