VANCOUVER, Oct. 27 /PRNewswire/ - Mercator Minerals Ltd. ("Mercator" or the "Company") is pleased to announce that the rougher cell expansion at Mineral Park was completed on schedule during the first week of October.  After 3 weeks of operation, copper recoveries have increased to 82% (versus target of 80%) and molybdenum recoveries have increased to 71% (versus target of 75%). The third quarter saw production of 9,032,269 lbs of copper, 1,236,443 lbs of molybdenum, and 135,136 ozs of silver, with recoveries of 75% and 58% for copper and molybdenum, respectively. All figures in this news release are management estimates and are unaudited.

Revenue from Mineral Park was $59.1 million during third quarter, with operating cash flow estimated at $24 million.

"The new roughers at Mineral Park are living up to expectations" said Mike Surratt, President and CEO. "We are still making system adjustments and training crews how to effectively run the new circuits, but we expect continued improvements in recoveries, particularly with respect to molybdenum" added Surratt.   

Third Quarter Production

For the third quarter of 2010, Mineral Park produced 8,125,396 lbs of copper in concentrates (Q2- 8,180,422 lbs), 864,635 lbs of cathode copper (Q1- 824,966 lbs), 1,236,443 lbs of molybdenum in concentrates (Q2-948,443 lbs), and 135,136 ozs of silver (Q2 - 117,185 ozs).

Mill throughput totalled 2.52 million tons (Q2 - 2.31 million tons) or 27,420 tons per day (Q2 - 25,371 tons per day), and averaged head grades of 0.22% copper (Q2 - 0.24% copper), 0.039% molybdenum (Q2 - 0.039% molybdenum) and 0.09 oz/ton silver (Q1 - 0.10 oz/ton silver).  Mined grades continue to meet or exceed planned grades.

Turbine Financing

The previously announced $21 million facility to fund a new gas turbine for Phase 2 operation at Mineral Park was completed October 21st. The turbine is scheduled for delivery the first week of December and is expected to commence operation in April of 2011. The unit is a 34 megawatt GE LM 6000 turbine that will, in concert with the existing grid usage, supply all of the power for the 50,000 tons per day Phase 2 expansion. 

El Pilar Update

El Pilar run of mine bulk testing has been operating for over 69 days with encouraging results. The test contains 300 tons apiece and are in 2 large concrete bins, referred to as "cribs". Crib 1 has demonstrated a calculated copper recovery rate of 51% over the 69 days, while Crib 2 has recovered 48% of calculated copper. The El Pilar feasibility study used 60% recovery over 120 days on material crushed to less than six inches. Contained grades within the pregnant leach solution ("PLS") have been high starting out at over 4 grams per liter and are still 1.39 grams per liter and 1.24 grams per liter after 69 days for Cribs 1 and 2, respectively. The high recoveries and good PLS grades after 69 days indicate that run of mine leaching could be a viable processing mechanism at El Pilar given its capital and operating advantages.
