MRK Merc International Minerals Inc.

Merc International Minerals Inc. ("Merc") (TSX VENTURE: MRK) reports results on seven additional drill holes from its recently completed 2010 Winter Drill Program at its Damoti Lake Gold Project, Northwest Territories. All holes were collared within the eastern limb of the Red Mountain syncline, located 125 metres west of the Horseshoe syncline and its associated high-grade gold mineralization.

Highlights include: Hole D10-416B which returned 16.12 grams gold per tonne over 8.0 metres, including 60.25 grams gold per tonne over 1.5 metres and 8.50 grams gold per tonne over 4.0 metres, including 18.12 grams gold per tonne over 1.5 metres; Hole D10-418 returned 7.93 grams gold per tonne over 3.00 metres, including 12.40 grams gold per tonne over 1.80 metres, and 2.60 grams gold per tonne over 16.25 metres, including 6.84 grams gold per tonne over 4.25 metres, and 17.90 grams gold per tonne over 1.25 metres. Drill hole D10-416B intersected extensive mineralization extending from near-surface, returning a composite grade of 1.64 grams gold per tonne over 151.40 metres. These intersections represent the best widths and grades ever reported for Red Mountain.

Drill holes D10-416, D10-416B, and D10-418 infill and extend, up to 75 metres in length, two of the five mineralized zones within the east limb of the Red Mountain syncline, and confirmed the presence of two new zones at depth. The intersections also collectively helped to better define a recently identified southeast/northwest trending mineralized corridor that includes the high-grade Horseshoe Zone (125 metres to the east) and a high magnetic feature in association with an induced polarization (IP) anomaly located 250 metres further east of Horseshoe. Historic work in this latter area returned several anomalous gold values in iron formation from surface samples. This portion of the property remains largely unexplored and highly prospective.

Two holes (D10-417 and D10-417B) drilled 40 metres south of hole D10-418, intersected mineralized zones at similar depths to those encountered in D10-418, as well as a new zone at depth. Two drill holes located further to the south of the Red Mountain - Horseshoe corridor (D10-423 and D10-423B) intersected the targeted iron formation but returned no significant assay results. For additional information on drill hole locations and Merc's drill program please visit Merc's website www.mercinternational.ca.

"We are very encouraged by the total length of mineralization intersected in hole D10-416B and its five internal higher grade zones. This was one of our priority drill targets chosen for its associated IP anomaly. A similar IP/magnetic anomaly also exists along the eastern perimeter of the mineralized corridor," stated Dr. Michael Byron, Merc President and CEO. "That area has yet to see any focused exploration activity. As our exploration model continues to evolve, this mineralized corridor will play a significant role in our exploration strategy and target identification."

Drilling at Red Mountain was designed to test the continuity of new mineralization discovered by Merc in 2009 and to expand these vertically stacked zones to the north and south. "Given the success in this new northern area of the Red Mountain syncline, Merc now awaits with great interest the results of additional holes that were drilled further north along the same structure," added Dr. Byron. "Positive results from these holes will significantly open up Red Mountain by extending the mineralization in excess of 200 metres northward."

Quality Control

Merc International Minerals Inc. has implemented a quality-control program to ensure best practice in the sampling and analysis of the drill core. NQ-size drill core is saw cut and half the drill core is sampled in standard intervals not exceeding 1.5 metres in length while core from the main mineralized horizons or core displaying visible gold or significant sulfides are sampled in greater detail generally not exceeding 1 metre in length. The remaining half core is stored in a secure location.

Core samples are transported in security-sealed bags for analyses at ALS Chemex Assay Laboratory, Vancouver, BC. ALS Chemex is an ISO 9001:2000 certified laboratory. Gold assaying is done by a fire assay - atomic absorption spectrometry method on a 30-gram charge of a 1,000 gram pulp. Samples returning values exceeding 3 gpt Au are re-checked by fire assay with a gravimetric finish. Pulp and metallics assaying for gold is conducted on the entire pulverized sample for all samples within the main mineralized horizons and those samples with visible gold or significant sulfides.

As part of its QA/QC program, Merc International Minerals Inc. inserts external gold standards (low to high grade) and blanks every 20 samples. This is in addition to the standards, blanks and pulp duplicates inserted by ALS Chemex. In addition, samples of pulps have been collected from ten percent of all samples analyzed and will be submitted to a second independent laboratory for comparison purposes.

The Damoti Lake Gold Project is being supervised by William Waychison, M.Sc.A., P.Geo., the Qualified Person (QP) for this project.
