Mercator Minerals Reports Second Quarter 2012 Production Results07:00 EDT Monday, July 09, 2012VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 9, 2012) -Mercator Minerals Ltd. (TSX:ML) ("Mercator" or the "Company") is pleased to announce production for the three months ended June 30, 2012 from its wholly-owned Mineral Park Mine ("Mineral Park") was 21.4 million pounds of copper equivalent*, which consisted of 9.5 million pounds of copper in concentrates and cathode copper, 2.6 million pounds of molybdenum and 155,000 ounces of silver.

In April, during the optimization process, the grinding media in both SAG mills were changed to a larger sizing and volume. While these changes had a positive effect on the throughput, it did result in increased liner wear and damage in the SAG mills. Due to these issues, SAG mill availability in May averaged 82% and required unscheduled liner changes in both SAG mills. Availability has subsequently increased to over 97% during the month of June."As we exit the second quarter we are seeing the benefits of our productivity improvement program. We are currently achieving our targeted throughput level of 50,000 tons per day and are exceeding our targeted metal recoveries, with copper greater than 80% and molybdenum greater than 79%," commented Bruce McLeod, President & CEO. "With the additional downtime during this quarter, along with further optimizing of operations, we have positioned ourselves well for sequential quarter over quarter increases in metal production as we meet our 2012 production goals."Quality Assurance/Quality Control Gary Simmerman, BSc Mining Eng, FAusIMM, Mercator's VP Mineral Park, a Qualified Person as defined by National Instrument 43-101, supervised the preparation of and verified the Mineral Park technical information contained in this release.

This information and these statements, referred to herein as "forward-looking statements", are not historical facts, are made as of the date of this press release and include without limitation, statements regarding discussions of future plans, guidance, projections, objectives, estimates and forecasts and statements as to management's expectations with respect to, among other things, the size, grade and quality of the Company's mineral reserves and mineral resources, potential mineralization, and possible extensions of zones. In addition, estimates of mineral reserves and mineral resources may constitute forward looking statements to the extent they involve estimates of the mineralization that will be encountered if a property is developed. These forward-looking statements involve numerous risks and uncertainties and actual results may vary. Important factors that may cause actual results to vary include without limitation, certain transactions, certain approvals, changes in commodity and power prices, changes in interest and currency exchange rates, risks inherent in exploration results, timing and success, inaccurate geological and metallurgical assumptions (including with respect to the size, grade and recoverability of mineral reserves and resources), unanticipated operational difficulties (including failure of plant, equipment or processes to operate in accordance with specifications, cost escalation, unavailability of materials, equipment and third-party contractors, delays in the receipt of government approvals, industrial disturbances or other job action, and unanticipated events related to health, safety and environmental matters), political risk, social unrest, and changes in general economic conditions or conditions in the financial markets. In making the forward-looking statements in this press release, the Company has applied several material assumptions, including without limitation, the assumptions that: (1) market fundamentals will result in sustained copper and molybdenum demand and prices; (2) the current copper leach operations at Mineral Park remain viable, operationally and economically; and (3) the milling operations at Mineral Park will continue to be viable, operationally and economically.
