Mercator Minerals Announces Letter of Intent to Increase
Financial Flexibility

Vancouver, British Columbia – October 22, 2012– Mercator Minerals Ltd. (TSX:ML) (“Mercator” or “Company”) is pleased to announce today that its wholly-owned subsidiary, Mercator Minerals (Barbados) Ltd (“MMBL”), has a non-binding letter of intent with Silver Wheaton (Caymans) Ltd. (“Silver Wheaton Caymans”), a subsidiary of Silver Wheaton Corp., to amend the silver purchase agreement (“SPA”).

“Consistent with our recently announced refinancing, the proposed amendment of the SPA would enhance our immediate financial flexibility and our ability to support low-risk, fast payback growth projects at Mineral Park,” commented D. Bruce McLeod, Mercator’s President & CEO. “We value our partnership with Silver Wheaton and appreciate their continued support in growing the Company.”

MMBL has a non-binding letter of intent with Silver Wheaton Caymans to amend the SPA. The amendment, once executed, will provide MMBL the right to exercise at any time until August 31, 2014 to defer delivery of up to 50% of required silver deliveries for one year. All deferred silver will be delivered in equal installments over 18 months after the one year deferral period. MMBL will compensate Silver Wheaton Caymans for any shortfall arising from a decrease in the silver spot price at the time of the original delivery date until the date of actual delivery, including a 12% annualized interest rate. The amendment will also grant Silver Wheaton Caymans a right of first refusal on any future precious metal streams relating to the El Creston project.

The amendment is subject to any necessary approvals, the negotiation and execution of definitive binding documentation, the amendments to the Mineral Park credit facility and El Pilar pre-construction credit facility being refinanced as previously announced, and certain additional security arrangements being put in place.
