Corporate Updates

- Reiterates Production Guidance for 2017 -

– Sherritt International Corporation (“Sherritt” or the

“Corporation”) (TSX:S) today announced that operations and production activities at its Moa

Joint Venture and Oil and Gas and Power facilities in Cuba hav e been restored to normal

capacity following a period of clean up and re-start in the aftermath of Hurricane Irma.

Sherritt also confirmed that none of its facilities incurred more than minimal damage, and that all

of its employees were safely accounted for.

“Although our production activities were interrupted by Hurricane Irma, the disruption was

relatively insignificant thanks to the considerable preparation and planning efforts we undertook

with our Cuban partners,” said David Pathe, President and CEO of Sherritt Int ernational. “As a

result, Hurricane Irma has not had any material impact on our e xpected 2017 production

emanating from Cuba. With production and op erations back to normal, we now look forward to

drill results from our oil exploration activities in the Bl ock 10 concession, which we anticipate in

Q4 of 2017.”

Sherritt recommenced drilling in Block 10, which is located in the Bay of Cardenas off of Cuba’s

north shore, on September 1 8. The drilling is being completed under a production sharing

contract with the state oil company, Cubapetroleo SA (Cupet).
