TORONTO, March 22, 2012 /CNW/ - Merc International Minerals Inc. ("Merc") (TSX Venture: MRK) is pleased to announce it has commenced its winter 2012 drilling program at its 100% owned Colomac Gold Property in the Northwest Territories.

Highlights:

• Merc has commenced its winter 2012 drill program at its Colomac Gold Property by deploying two diamond drills. Merc expects to drill 5,000 metres in the winter program followed up by an additional 10,000 metre drill program in the summer of 2012;
  
  
• Drills will test targets located within two high priority areas along the 7 kilometre long Colomac Dyke;
  
  
• Drilling objectives are to verify historic reports of a high-grade gold shoot at the Colomac Dyke South Zone, to confirm that gold mineralization extends to depth below the previously mined main pit at the Colomac Dyke Central Zone and to infill and expand the previously reported NI 43-101 compliant resource; and
  
  
• Construction of a large capacity exploration camp has commenced at Colomac, and is expected to be completed prior to the start-up of the 2012 summer drill program.

Following the receipt of its Land Use Permit, previously announced on February 29, 2012, Merc began moving materials to Colomac on the recently completed ice road. Construction of a large capacity exploration camp is currently in progress and is scheduled to be finished by early summer. The Colomac camp will become the main facility supporting all future activities within Merc's Indin Lake Gold Project area.

Both drills are currently drilling from ice setups on Baton Lake, testing mineralization to depth within the host quartz-feldspar porphyry dyke, (the Colomac Dyke). One drill will focus on infilling and expanding the current resource, as well as exploring for the presence of high-grade mineralized shoots below the main pit. The second drill is located 2.5 kilometres south along the west shore of Baton Lake.  Drilling at this location will verify historical reports of a high-grade gold shoot discovered within the Colomac Dyke South Zone by Royal Oak Mines in 1997. This type of mineralization represents a new opportunity at Colomac, as high-grade shoots were previously not recognized or explored for, nor have they ever been included in any previous Colomac resource calculation. Drilling is expected to continue in this area into the summer program.

Merc President and CEO, David Wiley, commented, "We are especially excited to announce that we have kicked off our winter 2012 drill program.  As previously mentioned, our focus with this phase of drilling at the Colomac Gold Property will be on expanding and upgrading our previously announced NI 43-101 Inferred Mineral Resource estimate.  In particular, we look forward to learning more about the potential of the high-grade gold shoot that has historically been reported to exist at the Colomac Dyke South zone.  If confirmed, we expect the high-grade shoot will have a positive impact on both the overall size and average grade of our resource."
