Mercator Production for Two Months Exceeds Projected Q2 2011 Production Guidance


VANCOUVER, June 7, 2011 /CNW/ - Mercator Minerals Ltd. (TSX:ML) ("Mercator", or the "Company") is pleased to announce that that for the first two months of Q2 2011, the Company produced 7,538,130 pounds of copper and 1,128,674 pounds of molybdenum at its wholly owned Mineral Park mine in Arizona, as compared to total Q2 2011 production guidance for the months of April to June, given on March 8, 2011 of 10,163,548 pounds of copper and 1,033,558 pounds of molybdenum, representing 74% of the guided quarterly copper production and 109% of the guided quarterly molybdenum production during a period of two months of a three month quarter, with a full month of production to come.  Improved mill performance, increased recoveries and increased mined tonnage accounted for the higher than expected production levels.  In addition, Mineral Park produced 56,953 ounces of silver in May.

  April May 2 Month Total Q210 Guidance
Copper Production 3,703,804 3,834,326 7,538,130 10,163,548
Molybdenum Production 610,017 518,657 1,128,674 1,033,558

"Our operating teams in the mill and the pit have continued to make improvements in all areas of production.  They deserve 100% of the credit for this exceptional performance," stated Mike Surratt, Mercator's President & CEO.

El Pilar Development Update

Mercator has completed two 300 tonne crib tests to determine run-of-mine ore leachability at its El Pilar SX/EW development project in Mexico. The completed tests demonstrate recoveries of 67.9% for Crib 1 and 63.7% for Crib 2 over 120 days.   The recoveries were very similar to the recoveries produced in column testing, where 67.5% recovery was achieved in 120 days.  As a result of this successful test program, Mercator is proceeding with an optimized feasibility study incorporating the run-of-mine development option for El Pilar.  Run-of-mine leaching will eliminate the capital and operating costs associated with the crushing plant for El Pilar.  The optimized feasibility study is expected to be complete in July.

"El Pilar is shaping up to be a very robust project and we are looking forward to building one of the larger copper heap leach operations in North America," said Mike Surratt.
