MRK Merc International Minerals Inc.

Merc International Minerals Inc. ("Merc") (TSX VENTURE:MRK) is pleased to
provide an overview of its recently completed 2010 Winter Drill Program at its
Damoti Lake Gold Project, located 200 km north of Yellowknife, Northwest
Territories. Results continue to outline broad zones of near-surface gold
mineralization, with associated high-grade cores.


This second phase of drilling, which focused on stepping out along strike from
historical work in the Horseshoe Zone and parallel iron formations, achieved
remarkable success as 83% of the holes intersected gold mineralization. Between
March 19, 2010 and June 5, 2010, Merc completed 42 drillholes for 7,985 meters.
Drill results were reported in four news releases: May 18, 2010; June 15, 2010;
July 6, 2010; Aug 4, 2010. Zones discovered at Red Mountain by Merc's 2009 drill
program were extended, and new high-grade vertically stacked zones were traced
over 200 meters north along strike of the host iron formation. For information
on Merc's drill program and results, please visit Merc's website

Red Mountain Zone

Zones discovered at Red Mountain by Merc's 2009 drill program were extended, new
high-grade vertically stacked mineralized zones were traced over 200 meters
north along strike, and other new zones discovered at depth. Fifteen holes were
collared within the eastern limb of the Red Mountain syncline, located 125
meters west of the Horseshoe Zone. This drilling has intersected the best widths
and grades ever reported for Red Mountain, successfully establishing Red
Mountain as a new priority target. For example, D10-416B returned a composite
grade of 1.64 grams gold per tonne over 151.40 meters, demonstrating the
continuity of extensive near-surface mineralization extends to depth. Hole
D10-420B, collared 165 meters north of D10-416B, intersected several of its
projected zones, including 20 meters of 5.60 grams gold per tonne, with a
subinterval of 9.80 grams gold per tonne over 8.5 meters, starting from 20
meters below surface.


In addition, the latest drilling has identified a mineralized corridor linking
the high-grade Horseshoe Zone (125 meters to the east of Red Mountain) and
coincidental magnetic and induced polarization (IP) anomalies located 250 meters
further east of Horseshoe. Merc is presently developing drill targets within
this highly prospective and unexplored area.


Northern Extension of Horseshoe Zone

Drilling was successful in extending the near-surface Horseshoe Zone
mineralization further to the north intersecting 5.03 grams gold per tonne over
3.5 meters, 14.95 grams gold per tonne over 0.5 meters; 1.0 meter of 14.66 grams
gold per tonne, including 0.5 meters of 28.20 grams gold per tonne; and 2.5
meters of 6.56 grams gold per tonne, including 0.5 meters of 22.90 grams gold
per tonne. These results demonstrate the ongoing potential of this promising
mineralized zone. Additional holes are needed to further evaluate/extend the
mineralization northward within the fold limb, an area that remains open. 


Other Zones

Two holes were drilled 200 meters southwest of Red Mountain in the nose of a
fold, referred to as the Runway Zone, and appear to have intersected the fringe
of a mineralized zone (3.5 meters of 3.49 grams gold per tonne, including 12.5
grams gold per tonne over 0.5 meter). Based on these encouraging preliminary
results, additional work is required in this new target area as it constitutes
another "Horseshoe-like" mineralized fold opportunity.


Drilling also confirmed and expanded the high-grade mineralization previously
reported for the BIF Island Zone, located 3.5 kilometers southwest along strike
of the Horseshoe Zone. Nineteen holes were drilled in the folded iron formation,
which is geological setting similar to the Horseshoe Zone. Holes primarily
tested shallow targets to a maximum vertical depth of 150 meters in order to
define the extent of the host iron formation and confirm a strong core of gold
mineralization conforming to the general plunge of the fold. This has resulted
in an enhanced geological model for gold mineralization outlining broad zones of
mineralization containing high-grade cores. The limits and expansion
opportunities of this mineralized zone will be further evaluated. 


Future Exploration Work

Given the relatively shallow nature and good continuity of the gold
mineralization at Damoti, Merc will conduct some preliminary evaluations on its
potential for an open pit operation. Additional drilling and exploration work
will be contingent upon the incorporation of the present drill results into an
expanded geological model to assist in target generation and evaluation. Future
work is being planned for, but not restricted to, the following areas:




--  The mineralized corridor that extends northwestward through the
    Horseshoe and Red Mountain Zones; 
--  Northern extensions of the Red Mountain and Horseshoe Zones; 
--  The Rangi target area that lies 150 meters east of the Horseshoe Zone
    and extends 2.5 km to the south.  



Work will also focus on exploring the mineralized Runway fold and the regional
unconformity/fault contact between mafic volcanic rocks and sedimentary rocks
that lies along the western portion of the Damoti claim group. This geological
setting of iron formation and regional fault zone is similar to portions of
Agnico-Eagle's Meliadine gold deposit, which reportedly contains more than 3
million ounces of gold.
