Sherritt Announces Ambatovy May Monthly Production Update and Receipt of Production and Efficiency Certificates

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

Sherritt International Corporation ("Sherritt" or the "Corporation") (TSX:S.TO) announced today the May 2015 operational results for the Ambatovy Joint Venture.

Operating results attributable to Sherritt at a 40% ownership basis are summarized in the following table:

For the month of May, finished nickel production was 1,550 tonnes (3,874 tonnes, 100% basis), or approximately 76% of nameplate capacity, and finished cobalt production was 103 tonnes (257 tonnes, 100% basis). Ore throughput in the pressure acid leach (PAL) circuit was 354,109 tonnes (100% basis), or approximately 71% of nameplate capacity.

May throughput and finished nickel production were impacted by the plant strike in April, an unexpected outage at the plant caused by a high voltage transformer failure, and consequent overload damage to the two ore thickeners. Unthickened ore is currently being processed directly through the PAL circuit, affecting ore throughput rates by around 15%. It is anticipated that one ore thickener will return to service in July and the other in Q3.

In May, the Ambatovy project lenders' independent engineer verified and signed both the Production and Efficiency certificates required to satisfy financial completion. Sherritt has now received seven of the 10 certificates required under the terms of the Ambatovy financing, with the remaining three certificates expected to be delivered prior to September 30, 2015.

Ambatovy has implemented a program to reduce head count as part of a wider campaign aimed at mitigating the effects of continued low metal prices. Approximately 1,100 Ambatovy employees and contractors have had their employment contracts suspended or been demobilized, reducing overall project head count by approximately 12%.
