Expedition Mining Inc.: 2012 Exploration Summary

Expedition Mining Inc. (TSX VENTURE:EXU) (the "Company") wishes to provide this
update and summary of results on the 2012 exploration programs carried out on
the Company's Nevada and Yukon projects.


In September and October a program of mapping and rock chip sampling was carried
out on the recently acquired Black Hills, Jenny Hill and the Slate Mountain
projects in Nevada. Grab samples collected during the initial prospecting of the
area showed gold associated with quartz veining. Gold values of up to 8.5g/t
over 1.5m were returned from the Black Hills property and 3.09g/t over 1.5m from
the Jenny Hill property during the recent program.


A soil geochemical survey was initiated over the three projects in November, and
is anticipated to be complete by January 2013. The Black Hills portion of the
survey will be complete by the time of the Christmas break. All analyses are
being carried out by ALS Chemex in Reno, Nevada.


The Long Canyon Project was recently added to the Company's portfolio of Nevada
gold projects and an initial program of mapping, rock chip sampling and a soil
geochemical survey are planned for January 2013.


The 2012 work program on the Joy and Mt. Mervyn was completed by Aurora
Geoscience personnel and consisted of additional mapping and rock sampling. The
majority of the work was carried out on the Joy project, with only a small
program on the Mt. Mervyn. Gold results were uniformly low in the rock samples,
with the exception of one vein sample containing 2.8g/t. Mapping of the Joy
property has not located any significant sections of calcareous sediments
leading the Company to conclude that the potential for Carlin style
mineralization is low. As a result, the Company intends to terminate the option
agreement on the Joy Property. The Company will maintain the Mt. Mervyn Project
until such time as a follow-up program can be implemented to fully evaluate the
property.


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


The Company also announces that an aggregate of 650,000 incentive stock options
have been granted to directors and officers at an exercise price of $0.10 per
share on December 14, 2012. The options are exercisable for a period of five
years, ending on December 14, 2017 and are subject to the requirements of the
Exchange and the Company's Stock Option Plan.
