Expedition and Aldrin Begin Trenching and Mapping Program on Yukon Brew Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 9, 2010) - Expedition Mining Inc. (TSX VENTURE:EXU) (the "Company") and Aldrin Resources Corp. (TSX VENTURE:ALN) are pleased to report that a trenching, sampling and mapping program has begun 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.

Expedition Mining recently contracted with Groundtruth Exploration of Dawson to complete a soil sample survey on the Brew property and the results have been analyzed and a follow-up trench program has been initiated to evaluate the significance of the gold anomalies defined by the soil sample program.

Approximately 2,615 samples were collected in the 2010 grid soil sample survey and preliminary assay results have increased the size of the gold in soils anomaly defined by the 2009 Ryanwood program (1360 soils). The completed grid 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.

The current trenching program has been designed to develop drill targets to be tested in a core drilling campaign planned for the 2011 field season. The complex geology identified in reconnaissance mapping suggests the Brew property is underlain by multiple northwest trending fault slices which coupled with anomalies outlined by a ground magnetometer survey indicate the property has the potential to host mineralization similar to that at the nearby White Gold and Coffee properties. The basic rock types at Brew include Devonian-age metavolcanic and metasedimentary rocks with an anomalous gold-molybdenum-mercury-arsenic-antimony-nickel soil geochemical signature with gold-bearing placer deposits in adjacent drainages.

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 company also intends to add additional soil sample grid lines to close off several open-ended gold anomalies which were identified in this year's program.

Expedition is also reviewing the logistics associated with rehabilitating a landing strip that is present on the Brew claim block. The runway is not usable at this time but would require minimum work to return it to operational condition allowing fixed-wing aircraft support for future exploration programs.

Expedition Mining is optimistic that at the end of this field season several drill targets will be identified on the Brew property and that the potential for discovering economic gold values will continue to improve.
