(Stated in US Dollars unless otherwise indicated)

TRADING SYMBOL: TSX - ML

VANCOUVER, May 17 /PRNewswire-FirstCall/ - Mercator Minerals Ltd. ("Mercator" or the "Company") reports its results for the three month period ended March 31, 2010. This release should be read with the Company's unaudited financial statements and management discussion and analysis available on the Company's website and filed on SEDAR under the Company's issuer profile.

After the accrual for interest and interest payments of $3.56 million ($3.45 million in interest accrued on the Notes issued by the Company in 2007) and $5.36 million in non-cash items including accretion, amortization and stock based compensation, the Company recorded a net loss of $11.5 million or $0.06 per share compared to a loss of $10.65 million or $0.11 per share for the corresponding period in 2009.

During the period, the Company generated revenues of $23.88 million, a 376% increase over revenues of $6.34 million in the first quarter of 2009 on the shipment of 6,000,374 pounds of copper in concentrates (2009 - 2,306,308 pounds), 628,490 pounds of molybdenum in concentrates (2009 - 94,094 pounds), 64,952 ounces of silver (2009 - 12,240 ounces) and 777,410 pounds of cathode copper (2009 - 1,175,128 pounds).

For the first quarter of 2010, Mineral Park produced 5,432,225 pounds of copper in concentrates (2009 - 2,306,308 pounds), 638,512 pounds of molybdenum in concentrates (2009 - 94,094 pounds), 64,952 ounces of silver (2009 - 12,240 ounces) and 777,410 pounds of cathode copper (2009 - 1,175,128 pounds).

Mill throughput totaled 2.04 million tons (2009 - 1.45 million tons) or 22,340 tons per day (2009 - 16,176 tons per day), and averaged 0.224% copper (2009 - 0.274% copper), 0.039% molybdenum (2009 - 0.021% molybdenum) and 0.115 oz/ton silver (2009 - 0.046 oz/ton silver). Mill recoveries averaged 60.1% for copper, 40.3% for molybdenum and 27.4% for silver. As previously announced recoveries in the first quarter were affected by circuit testing and tonnage testing and have seen significant improvements since. The Company has determined that underperforming recoveries were the result of insufficient retention time in the rougher flotation tanks and not enough horse power in the motors driving the agitators in the roughers. During the first part of the quarter, the Company added horsepower to two of the rougher motors and set up a bank of molybdenum rougher flotation cells to add retention time to the rougher tails. The net effect of these tests indicated positive results.

"Production at Mineral Park continues to improve, through the end of the quarter, with March and April showing clear indications of the improvements that have been made and we continue to make at Mineral Park," said Mike Surratt President and CEO. "We are making steady progress" Surratt stated. "With the increased horsepower and the incorporation of additional rougher flotation, leading to increased recoveries, we are increasingly confident that we can meet or exceed our design parameters over the coming months", said Michael L. Surratt, President and CEO.

    Financial Highlights for the Three Months ended March 31, 2010

    -  Revenues from copper, moly and silver sales for the three month period
       ended March 31, 2010 of $23.88 million compared to $6.34 million for
       the corresponding period in 2009;

    -  Production of 5,432,225 pounds of copper in concentrates (2009 -
       2,306,308 pounds), 638,512 pounds of molybdenum in concentrates (2009
       - 94,094 pounds), 64,952 ounces of silver (2009 - 12,240 ounces) and
       777,410 pounds of cathode copper (2009 - 1,175,128 pounds);

    -  Net loss for the three month period ended March 31, 2010 of $11.55
       million compared to a net loss of $10.65 million for the corresponding
       period in 2009.

    -  Estimated cash operating cost* on first quarter 2010 production of
       $2.67 for copper and $12.88 for molybdenum, also on a co-product
       basis;

As previously reported, subsequent to the end of the period, the Company closed the refinancing of and subsequently redeemed, in full, the $120 million 11.5 % notes. The new bank financing reduced current interest rates by more than half, from 11.5% to 4.83%, representing a savings of approximately $700,000 per month, representing a potential savings of $0.42 per pound of copper sold forward. While management believes the medium and long term fundamentals of copper are very good, the Company also structured a risk management program in support of the recent refinancing and the development plans for the expansion of Mineral Park and the El Pilar project in Mexico. A total of 145 million lbs of copper have been sold forward over a six year term at an average net price to the Company of $3.01 per lb, net of all costs. This forward sale totals less than 11% of the Mineral Park proven and probable mineral reserves as disclosed by the Company in the Annual Information form for the year ended December 31, 2010.
