VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 16, 2011) - Mercator Minerals Ltd. (TSX:ML) ("Mercator", or the "Company") is pleased to announce today it has achieved for a consecutive 90-day period an average mill through-put rate of 45,058 tons per day and also achieved average copper and molybdenum recoveries of 79.5% and 73.1%, respectively, at its wholly-owned Mineral Park Mine in Arizona.


This milestone satisfies the performance test required in the project loan agreement with the lending group, and reduces the cash sweep significantly down to 25% at the Mineral Park Mine, which will provide greater financial flexibility for the Company.


The performance test commenced on August 17, 2011 and was completed on November 14, 2011.


Bruce McLeod, President and CEO comments, "From the day we started commissioning the second concentrator line at Mineral Park, our operational group has done a tremendous job ramping up production and recoveries to successfully complete the performance test. Despite reduced crushing capacity in the early part of the test period, prior to the second crusher coming online on September 30, 2011, the operational group has proven that it is an innovative and experienced team that can rise to the challenge and also take great pride in their work."


On Behalf of the Board of Directors
