A correction from source is being issued with respect to the release disseminated on April 8, 2011 at 9:15am ET. The second bullet under the highlights section was missing some required information. The complete and corrected release follows.

Trevali Mining Corporation and Kria Resources Ltd. have received final approval from the Ontario Superior Court of Justice for a business combination, by way of a plan of arrangement, whereby Trevali has acquired all of the issued and outstanding common shares of Kria (the “Kria Shares”) and Kria has become a wholly-owned subsidiary of Trevali (the “Transaction”). The Transaction was approved by shareholders on March 30, 2011, received final court approval on April 6, 2011, and closed effective on April 7, 2011. Following closing of the Transaction, 87,663,745 common shares of the combined company (the “Trevali Shares”) are issued and outstanding, of which 20,992,250 Trevali Shares were issued to Kria shareholders (representing 23.95% of the issued and outstanding Trevali Shares).

“Trevali now possesses an enhanced production pipeline with two new polymetallic mines planned to come on-stream over the next several months, first in New Brunswick, Canada at the Halfmile deposit, followed by the Santander mine project in west-central Peru – providing shareholders with increased cash-flow growth potential, lower risk with multiple production platforms and a strengthened management team,” stated Dr. Mark Cruise, President and CEO of Trevali. “In conjunction with our mine development activity currently underway, the Company is also undertaking aggressive exploration and resource expansion drilling programs at Santander in addition to examining various options to unlock shareholder value from our Ruttan Copper deposit in northern Manitoba that also remains open for expansion.”

“We are very pleased to see the business combination with Trevali successfully close,” stated Mr. Mike Hoffman, President and CEO of Kria. “The overwhelming shareholder support for this transaction indicates that shareholders recognize the intrinsic value in combining the assets under one company and we all look forward to the months ahead as Trevali drives forward on the production and exploration fronts.”

Additionally, Trevali has completed the final US$5-million payment due to Xstrata Canada Corporation – Xstrata Zinc Canada Division (“Xstrata”) under the July 2008 (amended July 15, 2009) purchase agreement between Kria and Xstrata to acquire the Halfmile and Stratmat properties near Bathurst, New Brunswick.

HIGHLIGHTS

– Operations diversified across two world-leading mining jurisdictions, Peru and Canada. – Diversification from a single advanced project to two mine development projects, with production anticipated in 2011 – 2012 (feasibility studies have not been completed and there is no certainty that the deposits will be economically viable) – Significant increase in tonnages and contained metal in all resource categories, including over 1.7 billion pounds of indicated zinc resources and 2.8 billion pounds of inferred zinc resources, together with significant silver, lead and copper resources (Table 1). – Excellent resource expansion potential at Santander where all four newly discovered polymetallic deposits (Magistral North, Central, South and Puajanca South) and the historic Santander Pipe, remain open for expansion at shallow-to-moderate depths. – Robust, advanced project pipeline. – Quality exploration portfolio at the Santander and Ruttan projects – numerous high priority targets currently undergoing drill testing at Santander. – Trevali will have significant leverage to commodity price increases, specifically zinc, silver and lead in the near-term. – Listing on the TSX with a Lima Stock Exchange (BVL) listing in progress, anticipated to result in improved stock liquidity and strong re-rating potential. – World-leading strategic partners-Glencore International (at Santander) and Xstrata Zinc (toll-milling for Halfmile). – Expanded talent pool of experienced geoscientists, mining engineers,

management team and board of directors.
