Expedition Mining Inc. and Aldrin Resources Corp. Complete Phase I Work Program on Yukon Brew Property

VANCOUVER, BRITISH COLUMBIA -- (Marketwire - Aug. 25, 2010) - Expedition Mining Inc. (TSX VENTURE: EXU) (the "Company") and Aldrin Resources Corp. (TSX VENTURE: ALN) are pleased to report exploration progress on its Brew project located in the Yukon Territory approximately 20 kilometres east of Kinross/Underworld's White Gold project. 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.

In June, 2010 the Brew claim block was expanded by staking an additional 176 quartz claims to add to the original 168 claims staked in 2009 by Dawson prospector Shawn Ryan. The additional claims double the Brew property size to approximately 70 square kilometres or 17,250 acres. Shawn Ryan staked the original Underworld claims currently being explored by Kinross and also staked the nearby Coffee claim block being explored by Kaminak Gold Corporation. Preliminary soil sampling and reconnaissance prospecting indicate the Brew property contains geological and geochemical features similar to the White Gold and Coffee properties.

Expedition Mining recently contracted Groundtruth Exploration of Dawson to complete a soil sample survey on the Brew property. The recent sampling grid expands the original survey done by Ryanwood Exploration. This field season's soil program collected approximately 2,615 samples and preliminary assay results have increased the size of the gold in soils anomaly defined by the 2009 Ryanwood program (1360 soils). The completed survey indicates that there is a large gold in soil anomaly that coincides with arsenic, antimony and base metal elements located in three zones that appear to be related to a strong northwest-trending fault system that is likely associated with regional structures thought to control mineralization on other active prospects in the White Gold District. The Brew property gold in soil anomaly is now over two kilometres in length and surface metal values indicate a width of up to one kilometre. (See maps on website at www.expeditionmining.com.)

The company intends to complete additional soil sampling and a trenching and geological mapping program designed to focus on the gold, arsenic and antimony anomalies identified from this season's exploration activities. As assays are received, the trenching and geological mapping program will be expanded. Mr. Ron Atlas, President and Chairman said, "We are extremely lucky to have this opportunity. We are working with Shawn Ryan and his team, who are experienced in the Yukon, to help us bring this property to the drill-ready stage. Our proximity to the Kinross/Underworld's and Kaminak properties and our location in the White Gold District makes this one of the best opportunities we have ever had."

In the eastern grid area, the gold in soil zone is associated with anomalous molybdenum, mercury, arsenic, antimony and nickel (Ryan, 2009), in an area underlain by a complex zone of amphibolite (metavolcanic rocks), metasedimentary rocks, including marble lenses, and felsic orthogneiss. The complex geology may be suggestive of multiple northwest trending fault slices through this region, which is implied by the radarsat image (Ryan, 2009). The ground geophysical signature is not suggestive of skarn type mineralization due to the absence of magnetic high anomalies associated with the gold in soil anomalies. (J.Pautler, P. Geo. Brew Project Summary, 10/27/2009).

Circular topographic features on the Brew Project may reflect ring fractures associated with the doming effect of an underlying intrusion, possibly of Cretaceous age based on the presence of other Cretaceous intrusions in the area. (J.Pautler, P. Geo. Brew Project Summary, 10/27/2009). Mineralization at the Coffee property of Kaminak Gold Corporation has been found within the Cretaceous aged Coffee Creek pluton (Kaminak Gold website) and associated with possible similar aged felsic dykes (Dawson Rocks core shack, August 2010).

The Brew Project has potential to host mineralization similar to that at the White Gold and Coffee properties based on similar geological setting and geology (including Devono-Mississippian felsic orthogneiss, metavolcanic and metasedimentary rocks, with suggestions of a buried probable Cretaceous aged intrusion), gold-molybdenum-mercury-arsenic-antimony-nickel soil geochemical signature, and presence of nearby placer creeks. (J.Pautler, P. Geo. Brew Project Summary, 10/27/2009).

Expedition Mining is enthused about the potential of the Brew property and this year's program will add to the understanding of the mineralization contained on the property.
