Trevali Expands and Extends Debt Facility - Providing Additional Funds to Strengthen Balance Sheet

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec. 31, 2015) -

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Trevali Mining Corporation ("Trevali" or the "Company") (TSX:TV)(LMA:TV)(OTCQX:TREVF)(FRANKFURT:4TI) announces that it has amended, by way of entering into a supplemental indenture, its original note indenture with its senior secured holders ("Noteholders") of its $52.5 million senior secured notes (each a "Note" and collectively the "Notes") placed on May 30, 2014 (the "May 2014 Offering") to extend and expand the debt facility.

In light of the challenging commodity-price climate faced by the entire mining sector, the Company initiated discussions with its Noteholders in late-Q3 to seek adjustments under the Notes to both strengthen the Company's balance sheet and preserve working capital. Under the amended agreement, the Company has issued an additional $8.4 million in new Notes ("New Notes") and has received a waiver for the Company's $7.5 million amortization payment scheduled to be made on August 30, 2016 - which will now be deferred until August 30, 2017.

In relation to the above amendments and issuance of New Notes, the 6,468,000 5-year warrants issued in connection with the May 2014 Offering have been repriced downward from $1.26 to $0.475 (representing a 15% premium to the Company's 5-day VWAP ending December 24, 2015) and the term of such Warrants has been extended to a new five-year term. These existing warrants, as amended, cannot be exercised until 10 trading days following the date of this press release. In addition, in connection with the New Notes issued, an additional 1,034,880 5-year Warrants have been issued having an exercise price of $0.475. The Company has also agreed to seek standard anti-dilution protection of the Warrants in certain circumstances, subject to TSX pre-approval.

"We are very pleased to receive such a strong vote of confidence from our Noteholders, leading Canadian financial institutions, as we continue to advance our Caribou Zinc Mine towards commercial production," stated Dr. Mark Cruise, President and CEO of Trevali Mining. "Along with the Company, all stakeholders in the Caribou mine - the Province of New Brunswick, our First Nation partners and Glencore - continue to strongly support our operations and are working diligently to ensure the ongoing success of the project."

The Company has pledged to complete certain post-closing filings and registrations (principally filing on title in New Brunswick a revised amended debenture representing the increase in principal amount of the Notes outstanding) which it is required to complete by January 15, 2016.

This news release contains "forward-looking statements" within the meaning of the United States private securities litigation reform act of 1995 and "forward-looking information" within the meaning of applicable Canadian securities legislation. Statements containing forward-looking information express, as at the date of this news release, the Company's plans, estimates, forecasts, projections, expectations, or beliefs as to future events or results and the Company does not intend, and does not assume any obligation to, update such statements containing the forward-looking information. Such forward-looking statements and information include, but are not limited to statements as to: the intended use of proceeds in connection with the Offering, the accuracy of estimated mineral resources, anticipated results of future exploration, and forecast future metal prices, expectations that environmental, permitting, legal, title, taxation, socio-economic, political, marketing or other issues will not materially affect estimates of mineral resources. These statements reflect the Company's current views with respect to future events and are necessarily based upon a number of assumptions and estimates that, while considered reasonable by the Company, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies.

These statements reflect the Company's current views with respect to future events and are necessarily based upon a number of assumptions and estimates that, while considered reasonable by the company, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies. Many factors, both known and unknown, could cause actual results, performance or achievements to be materially different from the results, performance or achievements that are or may be expressed or implied by such forward-looking statements contained in this news release and the company has made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: fluctuations in spot and forward markets for silver, zinc, base metals and certain other commodities (such as natural gas, fuel oil and electricity); fluctuations in currency markets (such as the Canadian dollar and Peruvian sol versus the U.S. dollar); risks related to the technological and operational nature of the Company's business; changes in national and local government, legislation, taxation, controls or regulations and political or economic developments in Canada, the United States, Peru or other countries where the Company may carry on business in the future; risks and hazards associated with the business of mineral exploration, development and mining (including environmental hazards, industrial accidents, unusual or unexpected geological or structural formations, pressures, cave-ins and flooding); risks relating to the credit worthiness or financial condition of suppliers, refiners and other parties with whom the Company does business; inadequate insurance, or inability to obtain insurance, to cover these risks and hazards; employee relations; relationships with and claims by local communities and indigenous populations; availability and increasing costs associated with mining inputs and labour; the speculative nature of mineral exploration and development, including the risks of obtaining necessary licenses and permits and the presence of laws and regulations that may impose restrictions on mining, diminishing quantities or grades of mineral resources as properties are mined; global financial conditions; business opportunities that may be presented to, or pursued by, the Company; the Company's ability to complete and successfully integrate acquisitions and to mitigate other business combination risks; challenges to, or difficulty in maintaining, the Company's title to properties and continued ownership thereof; the actual results of current exploration activities, conclusions of economic evaluations, and changes in project parameters to deal with unanticipated economic or other factors; and increased competition in the mining industry for properties, equipment, qualified personnel, and their costs.
Investors are cautioned against attributing undue certainty or reliance on forward-looking statements. Although the Company has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, described or intended. The Company does not intend, and does not assume any obligation, to update these forward-looking statements or information to reflect changes in assumptions or changes in circumstances or any other events affecting such statements or information, other than as required by applicable law.

Trevali's production plan at the Caribou Mine is based only on measured, indicated and inferred resources, and not mineral reserves, and does not have demonstrated economic viability. Trevali's production plan at the Santander Mine is based only on indicated and inferred mineral resources, and not mineral reserves, and does not have demonstrated economic viability. Inferred mineral resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is therefore no certainty that the conclusions of the production plans and Preliminary Economic Assessment (PEA) will be realized. Additionally, where Trevali discusses exploration/expansion potential, any potential quantity and grade is conceptual in nature and there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

We advise US investors that while the terms "measured resources", "indicated resources" and "inferred resources" are recognized and required by Canadian regulations, the US Securities and Exchange Commission does not recognize these terms. US investors are cautioned not to assume that any part or all of the material in these categories will ever be converted into reserves.

This news release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the United States. The securities described herein have not been and will not be registered under the United States Securities Act of 1933, as amended, or the securities laws of any state and may not be offered or sold within the United States, absent such registration or an applicable exemption from such registration requirements.
