VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 01/31/13 -- Trevali Mining Corporation ("Trevali" or the "Company") (TSX: TV)(TSX: TV.WT)(OTCQX: TREVF)(LMA: TV)(FRANKFURT: 4TI) is pleased to announce that it has entered into a Limited Environmental Liability Agreement ("Agreement") with the Province of New Brunswick ("Province") regarding the historic environmental liabilities ("Historic Liabilities") at the Caribou mine and mill complex located in the Bathurst Mining Camp. Under the Agreement, Trevali will be responsible for all environmental liability and reclamation costs associated with the Caribou Mine on closure, other than in respect to any historic liabilities.

"This is an important milestone in the Trevali project and will bring it one step closer to creating many jobs in Bathurst region. At the same time it will be critical in helping to protect the environment for many years to come. The province of New Brunswick will continue to work closely with the Trevali team to assure success in re-activating Caribou operations. We look forward to our continued working partnership with the company," said New Brunswick's Energy and Mines Minister Craig Leonard.

"We are very pleased to complete this milestone with the Province of New Brunswick following our recent acquisition of the Caribou mine and mill in the Bathurst Mining Camp," stated Dr. Mark Cruise, Trevali's President and CEO. "With this agreement in place Trevali can now move another step forward in its near-term activation plans for its Caribou and Halfmile operations, which will form the foundation for the Company's long-term growth strategies in the Bathurst Mining Camp."

The Agreement is based upon a report entitled "Program for the Protection, Reclamation, and Rehabilitation of the Environment" ("Reclamation Plan") prepared by Stantec Consulting Ltd. and submitted to, and approved by, the New Brunswick Department of Energy and Mines.

In keeping with the Company's corporate philosophy to minimize environmental impact, Trevali will also use its best efforts to use existing waste rock stored on surface at Caribou, in the form of roads, containment dikes and waste dumps, as backfill in the underground operations. Additionally Trevali has agreed to allow the Province the option to store and dispose of Restigouche mine waste rock at the Caribou site, thereby providing the Province with a lower-cost and fast-track reclamation solution for the former Restigouche site.
