Trevali Resources Corp. ("Trevali" or the "Company") (TSX:TV)(FRANKFURT:4TI)(OTCQX:TREVF) announces that at its Special Meeting of Shareholders held on March 30, 2011, shareholders unanimously voted in favour of its proposed acquisition of Kria Resources Ltd. ("Kria") by way of plan of arrangement (the "Arrangement"). 15,901,261 Shares or approximately 25.1% of the Company's issued and outstanding common shares were represented at the meeting in person or by proxy. All of the shares represented at the meeting voted in favour of the transaction. The proposed Arrangement and related shareholder resolutions were detailed in the Joint Information Circular of Trevali and Kria dated February 22, 2011. 

Completion of the Arrangement remains conditional on the final approval of the Ontario Superior Court of Justice and satisfaction of other customary conditions, including regulatory and stock exchange approvals. Subject to the satisfaction or waiver of all conditions precedent, it is currently anticipated that the Arrangement will be completed on or about April 6, 2011.

"The overwhelmingly strong support by both Trevali and Kria shareholders in favour of our planned acquisition of Kria is testament to the positive synergies the two companies bring to the table," said Dr. Mark Cruise, President and CEO of Trevali. "The new company will boast a robust project pipeline with two new planned polymetallic mines coming on-stream over the next several months, first in New Brunswick at the Halfmile Project and then followed by the Santander Project in Peru."

Upon the pending completion of the Transaction, the combined company (planned to be renamed Trevali Mining Corporation) will have approximately 84.3 million issued and outstanding common shares and, Trevali and Kria shareholders will own approximately 75.1% and 24.9% of the combined company, respectively.

ABOUT KRIA RESOURCES LTD

Kria Resources is a base metal exploration and development company focused on high-quality, advanced-stage base metal assets. Kria's primary asset is the Halfmile Lake and Stratmat properties near Bathurst, New Brunswick. The Halfmile Lake and Stratmat projects are optioned by Kria from Xstrata, which is currently the largest shareholder of Kria. Kria completed a preliminary economic assessment ("PEA") on its Halfmile Lake project in September 2010 that indicated the project's economics improve if the mineral resource from Kria's nearby Stratmat property is combined with the mineral resource from Halfmile Lake.
