Expedition Mining Inc.: 2012 Exploration Program Commences on the Joy and Mt. Mervyn Properties

Expedition Mining Inc. (TSX VENTURE:EXU) (the "Company") wishes to announce that
it has commenced the 2012 field program on the Joy and Mt. Mervyn Projects.
Crews have mobilized to open the camp and the field work started on July 7th.
The properties are located between the Kathleen Lakes Fault and the Dawson
Thrust, along the Rackla Gold Belt in the Yukon. The target is Carlin-type gold
mineralization similar to that currently being drilled by ATAC Resources and
Strategic Metals on their adjoining properties. 


The work program will focus on those portions of the properties that contained
multi-element geochemical anomalies, geophysical targets and prospective
geology. The geochemical anomalies are believed to be significant as they
include the important pathfinder elements of As, Sb, Hg and Tl which have been
associated with gold mineralization at the Rau and Nadaleen trends of ATAC
Resources, and the Crag showings of Strategic Metals. 


"Exciting discoveries have been made on properties adjacent to the Joy & Mt.
Mervyn properties and it is essential that the Company establish whether it has
viable Carlin type gold targets on our claims," said Ron Atlas, President of
Expedition Mining. "This program is designed to do that in the most efficient
and economical manner."


Prospecting in 2011 resulted in the discovery of two showings (Virga and
Kermoda) associated with the lower contact of the ultramafic unit on the Joy
property. Silver, lead-zinc mineralization is associated with quartz carbonate
veining. The showings are also highly anomalous in As, Cd, Hg, Sb and Tl along
with elevated gold. Rock sampling in the area of the showings has exposed strong
mineralization as shown in Table 1.

The mineralization identified to date is associated with extensive, and locally
intense, quartz-carbonate alteration zones. These zones show a strong
correlation to the east-west trending thrust slices of the Dawson Thrust,
particularly in the vicinity of cross-cutting northerly trending structures. 


Geological and logistical support for the program is being provided by Aurora
Geosciences, who constructed a 15 man camp on the Mt. Mervyn property in 2011. 


Mr. James Chapman, P.Geo, is the Qualified Person responsible for the design of
the program, and all exploration work on the Joy and Mt. Mervyn Properties will
be done under his supervision. Mr. Chapman has read and approved the technical
content of this news release.
