MRK Merc International Minerals Inc.

Merc International Minerals Inc. ("Merc") (TSX VENTURE: MRK) is pleased to announce the staking of mineral claims contiguous to its Damoti Lake Gold Project. Additional ground was acquired along strike of the host iron formation to the north of the resource area and to the west along the volcanic rock/sedimentary rock contact, an area of known historic gold surface showings. Approximately 1,542 hectares were staked, adding to Merc's previous land holdings of 2,849 hectares.

In a recent news release (April 2, 2009) it was reported that mobilization of a diamond drill rig and drilling equipment to the Damoti Lake Gold Project, located 200 km north of Yellowknife, Northwest Territories, was completed in preparation for a 6,000 metre drill program scheduled for early June 2009. The Damoti Lake Gold Project has been the focus of several previous surface exploration and diamond drill programs, some of which have produced resource estimates as illustrated in the table provided below.

(i) These historical resource calculations are believed relevant but should
not be relied upon until verified. These historical estimates did not use
mineral resource categories as stipulated in NI 43-101.

(ii) Resource calculated with an 8 gram gold per tonne cutoff to facilitate
the evaluation of a small high-grade mining operation restricted to the
Horseshoe zone.

The Company's ongoing 2009 exploration program is designed to expand upon the known resource and consists of compiling all historical data, auditing historical resource estimates, constructing an updated three dimensional deposit model, defining and testing drill targets, and initiating a NI 43-101 resource estimate for the entire deposit. Twenty to thirty drill holes are planned to infill priority target areas within the current resource and to extend the mineralized zones along strike and to depth within the Horseshoe and Pyrite Zones. Drilling will also focus along the mineralized structures immediately west of the Horseshoe Zone within the Red Mountain, Pink Antler and Lookout Zones.

In November 2008, Merc secured $2.0 million in flow-through financing to support the 2009 Damoti drill program, which is expected to be completed by October 2009. In late 2009 an updated NI 43-101 complaint resource will be completed using all drilling to date within the Horseshoe zone (135 drill holes) as well as the drilling completed in the 2009 program (20 to 30 holes). This NI 43-101 compliant resource will make use of approximately 63 holes not included in the 1997 and 2004 resource estimates. Management believes this should result in an increase to the previous resource figures.
