Zincore and First Quantum Extend Date for Signing Formal Dolores Joint Venture Agreement

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 07/13/12 -- Zincore Metals Inc. (TSX:ZNC)(LMA:ZNC) ("Zincore" or the "Company") reports that the date for signing the Formal Agreement outlining the Dolores joint venture details with First Quantum Minerals Ltd ( "FQM" ) has been mutually extended by both companies. As originally described in the Company's news release dated May 8th, 2012, it had been anticipated that the Formal Agreement would be completed within 60 days of the signing of the binding Memorandum of Understanding ("MOU").

Zincore President and CEO, Jorge Benavides, commented, "Together with FQM we have made significant progress on documenting the strategic partnership over Dolores. The process for producing the Formal Agreement which maps out the Dolores joint venture details has however taken longer than anticipated. We expect to conclude the documentation shortly and will report back to the market on completion."

Mr. Benavides further commented, "First Quantum has already completed a private placement of C$3.8 million at $0.20 share into Zincore and purchased an additional 22,953,871 Zincore common shares in the secondary market to bring their ownership level in the Company to 19.99%. We have also appointed Mr. Mike Parker, the First Quantum-nominated representative, to our Board of Directors. Suffice to say, we have already developed an excellent relationship and look forward to continue to develop this relationship with completion of the Formal Agreement."

Under the terms of the signed and binding-MOU, First Quantum can earn up to an 80% interest in Zincore's Dolores project over eight years by achieving specified objectives.
