Expedition Commences Work Program on Joy and Mt. Mervyn Properties Along the Rackla Gold Belt

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 23, 2011) -

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

Expedition Mining Inc. (TSX VENTURE:EXU) (the "Company") wishes to announce the commencement of the 2011 work program on the Joy and Mt. Mervyn properties located along the Rackla Gold Belt in the Yukon. A helicopter supported camp has been set up on the Joy property at a location close to the Rackla River airstrip to facilitate logistical support. The Joy camp will serve as a central base camp for exploration work carried out on both projects.

The 2011 work program consists of detailed ground follow-up of prospective targets identified by the recently completed airborne EM and magnetic survey. This survey (News Release June 20, 2011) was successful in delineating numerous highly prospective anomalies on both the Joy and the Mt. Mervyn projects. The first phase of the 2011 field work consists of stream sediment sampling and prospecting. This will be followed up with geological mapping, rock and soil sampling over areas that return elevated metal values in stream samples.

In the region of the Joy and Mt. Mervyn properties the strongest geophysical anomalies are east-west trending, and appear to coincide with the projected locations of the Kathleen Lakes fault and the Dawson thrust. The majority of the secondary drainages in this area are north-south trending and are expected to provide good sections and exposure through the stratigraphic sequence. This will increase the effectiveness and exploration value of the stream sampling and prospecting program.

Geological and logistical support for the program is being provided by Aurora Geosciences.

The Company also wishes to announce that it has terminated its joint venture agreement with Aldrin Resource Corp. and has returned the Brew property back to Aldrin pursuant to the terms of the joint venture agreement. The Board has chosen to concentrate on the Joy and Mt. Mervyn properties which have shown exciting potential and in which the company holds 100% interest.

Information with respect to the Joy and Mt. Mervyn properties contained in this news release is approved by Bert W. Jeffries, PGeo, a qualified person required under National Instrument 43-101.
