("Mercator" or the "Company") is pleased to announce its production results for June 2010, totaling 3,089,472 lbs of copper, 396,184 lbs of molybdenum and 44,596 ounces of silver in concentrates. June was a record month for molybdenum production. These results bring second quarter production to 9.0 million lbs of copper, 0.95 million lbs of molybdenum and over 100,000 ounces of silver in concentrates. All figures in this news release are management estimates and are unaudited.

Revenues of $23.8 million were also a record for June and bring the second quarter revenues from Mineral Park to $56.1 million. Estimated operating cash flow for Mineral Park for the second quarter was $25.6 million.

"We are very pleased with the mine's progressively improved performance since the beginning of the year, and applaud our mine and plant staff for an impressive and record month at Mineral Park," said Mike Surratt, President and CEO.

Production & Operating Cash Costs per pound

During the three months ended June 30, 2010, the Company recorded estimated operating cash costs* of $1.88 per pound of copper and $9.97 per pound of molybdenum on a co-product basis (costs are divided proportionally based on the percentage of revenue from copper and molybdenum and the netting of silver revenue equally). Second quarter 2010 production was 9.0 million pounds of copper and 948,443 pounds of molybdenum and 117,185 oz. of silver.

Copper & Molybdenum Recoveries

Molybdenum recoveries increased to 57.7% in June as compared to 54.5% in May for the entire second quarter, copper recoveries averaged 73.8% compared to 60.1% for the first quarter, while molybdenum recoveries averaged 52.1% in the second quarter compared to 40.3% for the first quarter.

Additional rougher tanks are on schedule for startup the end of September. The first 3 tanks are on site and the concrete will be complete the second week of July. Support steel for the rougher tanks is being set. These tanks will provide more residence time for molybdenum and copper, with the objective of further improving recoveries.

Cash Costs per ton

Operating cash costs per ton* have also continued to improve, with estimated second quarter milling costs of $4.89 per ton milled and mining costs of $1.09 per ton mined. This compares with operating cash costs per ton* in the first quarter 2010 of $5.60 per ton milled and mining costs of $1.20 per ton mined.
