Sherritt Confirms Mineral Reserves and Outlines Increased Mineral

Resources at Moa JV

TORONTO, June 26, 2019 – Sherritt International Corporation (“Sherritt”) (TSX:S), a world leader

in the mining and refining of nickel and cobalt from lateritic ores, today filed on SEDAR an updated

National Instrument 43 -101 Technical Report (the “ 2019 Technical Report”) for the Moa Joint

Venture (“Moa JV”) that confirms the Moa JV’s current Mineral Reserve estimates and outlines

increased Mineral Resource estimates with the potential to increase Moa’s mine life.

“Backed by updated technical and economic data, the 2019 Technical Report confirms that Moa

is a low-cost, long-life asset with the potential to significantly increase the mine life,” said David

Pathe, President and CEO of Sherritt International. “ With a minimum 15 -year mine life, Moa

favorably positions Sherritt to capitalize on the growing demand for electric vehicle batteries as a

supplier of high quality, ethically-sourced Class 1 nickel and cobalt.”

The 2019 Technical Report, which was prepared in compliance with National Instrument 43-101

– Standards for Disclosure for Mineral Projects (“NI 43-101”), was prepared for Sherritt by CSA

Global with an effective date of December 31, 2018. The 2019 Technical Report updates technical

and economic data referenced in Sherritt’s 2018 Annual Information Form (“AIF”) dated February

13, 2019.

Highlights of Mineral Reserve and Resource Estimates

A comparison of the mineral reserve estimates in the 2018 AIF and 2019 Technical Report is

summarized in the following table:

2019 Technical

Report Total

The 2019 Technical Report introduced several changes to the methodology used previously to

determine the Moa JV’s Mineral Reserves estimates but arrived at no material changes to either

the total Mineral Reserve estimates’ tonnage or grade.

Inferred

The 77 % increase in Measured and Indicated Resources estimates determined by the 2019

Technical Report was primarily driven by the use of an economic cut-off grade that was marginally

lower than the fixed cut-off grade used previously.

With the increase in Measured and Indicated Resource estimates, Moa’s mine life has the

potential for significant extension if the estimates are upgraded to Proven and Probable Mineral

Reserves categories. The Moa JV currently has an estimated mine life of 15 years through 2033

based on Mineral Reserves estimates.

The Moa JV explores, develops, mines and processes nickel laterite deposits in Cuba for refining

into finished nickel and cobalt from a refinery in Fort Saskatchewan, Alberta and marketed to

customers internationally. In 2019, Sherritt and the General Nickel Company S.A. will celebrate

the 25-year anniversary of the formation of the Moa JV

The 2019 Report, which is available from Sherritt’s profile page on www.sedar.com, was prepared
