VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 7, 2011) -

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

Expedition Mining Inc. (TSX VENTURE:EXU) (the "Company") and Aldrin Resource Corp. (News - Market indicators) are pleased to announce that plans are well under way for the upcoming 2011 work program on the Brew property, in the White Gold District, Yukon. The program will include additional soil sampling, as well as a trenching program designed to develop targets to be tested in a core drilling program. Expedition Mining is conducting exploration on the Brew property under a joint venture agreement with Aldrin Resource Corp. whereby Expedition can earn a 50% interest in the property.

Ground Truth Exploration Inc. will be conducting an extensive soil sampling program totalling 3,000 samples on the Brew property in the 2011 field season. The existing soil grid will be extended to the East following a linear gold-in-soil anomaly outlined in the 2010 sampling program. Grid samples will be collected at 50 metre station and 100 metre line spacing. The remainder of the property will be sampled with ridge and spur traverses to outline additional targets within the Brew property. Ridge and spur samples will be collected at 50 metre sample spacing. (For additional information, soil sample map is posted on our website at www.expeditionmining.com.)

During the 2010 field season approximately 3,496 soil samples were collected, and the results expanded and better defined the extent of several open-ended gold anomalies in the Central zone along the main northwest trend. The soil surveys delineated a three kilometre long gold anomaly across the central grid area, and one kilometre north the soil sampling identified a second three kilometre long gold anomaly. Due to early winter conditions in 2010, only five trenches were completed, with four completely chip sampled. The highest in-soil values (maximum of 874.1 parts per billion gold) have not been trenched. During the 2011 field season, seven trenches are planned to evaluate the highly anomalous gold zones. 

Significant fault zones, identified by highly brecciated and silicified host rock were intersected in the Brew trenches which also exposed iron-rich gossan material containing anomalous gold values in the brecciated zones. The trenches exposed gossan material up to 45-metres in length in the trenches. Elevated iron numbers from the trench samples suggest the rock originally contained high percentages of sulphides which may have mobilized gold during oxidation.

Expedition has contracted Aurora Geosciences Ltd. of Whitehorse, Yukon to manage the 2011 exploration program at the Brew property. In mid-May, Aurora will conduct shallow diamond drilling beneath Trenches 10-1 and 10-2 to obtain fresh samples of mineralized rock, using a Packsack drill to test the fault zones to a depth of 20 m below ground level. Thereafter, additional soil sampling and trenching will be conducted in the Central Zone in mid-July to locate a bedrock source for the gold soil anomalies. After reviewing the 2010 results Jean Pautler, P.Geo., made the following recommendations: Several of the five trenches excavated in 2010 will be deepened and additional trenches will be excavated. Logging and sampling should be completed by early August. The Company is making preparations to complete a conventional diamond drill program in September, contingent upon favourable trench program results. All exploration work on the Brew property will be conducted under the supervision of Dave White, P.Geo., a Qualified Person with respect to National Instrument 43-101.

Information with respect to the Brew property contained in this press release is approved by Bert W. Jeffries, P.Geo., qualified person required under National Instrument 43-101.
