Expedition Mining Commences Trenching Program on Long Canyon Gold Property

Expedition Mining Inc. (TSX VENTURE:EXU) (the "Company") is pleased to provide
this update on the 2013 exploration programs within the Walker Lane Mineral
Belt. 


LONG CANYON PROPERTY 

This property consists of 37 unpatented lode claims located 200 kms southeast of
Reno and 16 kms southeast of the community of Mina, Nevada. Previous rock
sampling has returned gold values up to 1.7 g/t over 3 m, and up to 9.7 g/t gold
and 529 g/t silver in grab samples, and soil samples of over 1.0 g/t gold. The
property hosts an extensive siliceous zone containing strongly anomalous mercury
(to 155,000 ppm), antimony (to 987 ppm) and arsenic (to 2,790 ppm) values.  


Structurally the Long Canyon project area is dominated by strands of the
northwest trending Walker Lane Fault Zone. Arcuate splays from the main faults
trend east-west across the property and are exposed in many of the drainages.
The northerly trending structures extend through the Pilot Mountains to the
north, and are covered by pediment fans to the south. The intersections of these
structural zones are believed to be important localizing features for the
mineralization encountered at the Bellville Mine and the deposits in the Douglas
Camp. 


Exploration programs carried out by the Company have identified several
structural trends associated with multi-element soil anomalies. These structural
zones trend dominantly north-northeast and northwest, and intersect beneath the
siliceous zone which occupies the central portion of the property. The
north-northeast trend is characterized by swarms of narrow quartz veins with a
general northerly orientation and subvertical dip. These veins range from less
than 1 cm to greater than 1 m in thickness. At least two of these NNE zones have
been identified to date. Veins within the NW trending zone show a greater
variation in dip attitude from -45 to vertical, and are generally oriented
sub-parallel to the overall Walker Lane belt. 


Compilation of the results of the Expedition programs with the historical IP
data has shown that the zones of structural intersections correlate with the IP
anomalies and with the multi-element soil geochemical anomalies. These areas
have been chosen for the initial trenching program. Approximately 250 m (800
feet) of trenching are planned for six trenches. The trenches will be oriented
perpendicular to the dominant structural trend in order to maximize exposure of
the vein systems. 


The Long Canyon project is situated in southeastern Mineral County and is
flanked by several well known historical mining districts. The Pilot Mountains
to the north have a long history of mercury production, followed by tungsten
mining along the eastern edge of the range. The former producing Belleville Mine
8 kms north of Long Canyon reportedly produced around 100,000 ozs to 1939 from
two quartz veins.  


To the west, the Douglas Camp area was dominantly a gold and silver camp which
also contained abundant scheelite and produced over $1,000,000 of tungsten
during and after WW I. 


To the southwest, the Candelaria District was known for high grade silver
deposits which averaged 60 oz/ton in the early days of mining. By 1999 over 68
million ounces of silver had been extracted from the mines in this district.
