Mercator Provides Update on its Mineral Park Mine & El Pilar Project

All currencies in US$ unless otherwise specified.

VANCOUVER, Aug. 9 /CNW/ - Mercator Minerals Ltd. ("Mercator" or the "Company") (ML: TSX) today reported that July production for its Mineral Park copper-molybdenum mine continued in line with the improved results achieved in the second quarter of 2010, producing 2,846,238 pounds of copper, 396,322 pounds of molybdenum and 34,610 ounces of silver during the month. Tons processed and metal recoveries were also in line with the prior quarter and management expectations. All figures herein are management estimates and are unaudited.

Mineral Park Mine

As noted above, production improvements achieved during the second quarter of 2010 were sustained through July, with similar monthly levels of tons processed, recoveries and metals produced. Mercator expects to continue at these performance levels until the additional flotation tanks are brought on line and then, subsequently, the Phase 2 expansion is completed.

As part of its Phase 2 expansion to 50,000 tons per day processed, Mercator reports that construction of the rougher flotation expansion continued on schedule with 3 of the 6 tanks installed, the fourth tank on site, the fifth on the road and the sixth ready for shipment. All the structural concrete is complete and support steel is being installed. The tanks are scheduled for start-up the end of September and will provide additional retention time, which is expected to further improve copper and molybdenum recoveries. Three of the four Phase 2 ball mill shells are on site and the remaining parts are in transit between the Houston port and the mine. All the concrete for the Phase 2 ball mills is complete and the mechanical is in progress. The Phase 2 thickner is complete as well as the Phase 2 SAG mill.

El Pilar Project

During the month of July, the El Pilar bulk sample was mined and shipped to Mineral Park for run-of-mine leach tests. Over 600 tons of copper ore were extracted from several pits and trucked to Mineral Park, where the entire sample was screened, sampled, re-combined and placed in two large cribs or leach cells. Solution application has started and will be processed through a pilot scale SX plant over the next several months in order to determine whether heap leaching of run-of-mine material can deliver economically competitive recoveries as compared to prior plans to crush the mineralized material before stacking and leaching. Processing run-of-mine material could result in significantly reduced capital and operating costs. In parallel, heap leach pad optimization engineering is progressing on schedule in order to optimize the leach pad design in order to reduce costs.

Senior Management Appointment

Mercator today also announced that it has hired Joe Campbell as Vice President responsible for the EL Pilar Project. Mr. Campbell has over 25 years of operating experience, including extensive SX/EW experience. In addition, Mr. Campbell worked extensively in Mexico and South America. "We are very pleased to have someone with Joe's expertise and experience to lead our El Pilar team," said Mike Surratt, President and CEO.

Gary Simmerman, BSc., Mining Eng. FAusIMM, Mercator's VP Engineering, a Qualified Person as defined by NI43-101, supervised the preparation of and verified the technical information contained in this release.
