TORONTO, January 12, 2018 – Sherritt International Corpora tion (“Sherritt”) (TSX:S) today ann ounced

its 2017 production results and provided guidance for expected production , unit costs and capital

spending in 2018. All amounts are in US dollars, unless otherwise noted.

Highlights

 Finished nickel and cobalt production at Sherritt’s Moa Joint Vent ure (JV) was 31,523 tonnes and

3,601 tonnes, respectively, which is within 2017 guidance ranges.

 Nickel production at the Moa JV for 2018 is forecasted at between 31,500 tonnes and 32,500

tonnes on a 100% basis.

 Cobalt production at the Moa JV for 2018 is forecasted at between 3,500 and 3,800 tonnes on a

100% basis.

 Net direct cash costs (NDCC) at the Moa JV are forecas ted at between $2.50 and $3.0 0 per

pound of finished nickel reflecting higher anticipated sulphur and energy input costs.

 Gross oil production in Cuba is forecasted at between 4,300 and 4,800 barrels per day in 2018.

 Expected oil production for 2018 reflects a three-year extension of the Puerto Escondido/ Yumuri

production sharing contract to 2021, which has received approval from the Executive Committee

of the Council of Ministers of the Republic of Cuba.

 Total capital spending in 2018 is expected to be $94 million , and will include $41 million of capital

spending at the Moa JV and $39 million of spending for Oil and Gas operations. Spending at the

Oil and Gas Operations may vary depending on the rate of collection of overdue receivables.

Nickel and cobalt prod uction at the Moa JV in 2017 was in line with guidance. Ambatovy’s nickel and

cobalt production for 2017 were below guidance due to a number of factors, including acid plant

1 Nickel and cobalt production are presented on a 100% basis. Sherritt’s share varies by business unit, with the Moa

JV being a 50% joint venture, Ambatovy a 12% investment in an associate, and Power a 331/3% interest.

2All 2017 guidance figures are as of Q3 2017 as reported on October 24, 2017.

equipment failures resulting in reduced acid availability and reliability issues relating to the pressure acid

leach circuit, and other unplanned maintenance activities.

In 2018, nickel and cobalt production at the Moa JV is forecasted at between 31,500 and 32,500 tonnes

and 3,500 and 3,800 tonnes, respectively, on a 100% basis. The forecasted totals are consistent with

2017 results, but slightly lower than historical averages due to a number of factors, including , the impact

of heavy rains in Q4 2017 that inhibited mining and is expected to negatively impact mix ed sulphide

availability in Q 1 2018, and the expected reduced availability of third -party feed due to increasingly

competitive market demand.

Gross oil production in Cuba is forecasted at between 4,300 and 4,800 barrels per day in 2018. The

forecast is based on the rene wal of the Puerto Escondido/ Yumuri production sharing contract given the

approval received from the Executive Committee of the Council of Ministers of the Republic of Cuba . The

production forecast for 2018 also reflects the expiration of the Varadero West production sharing contract

previously disclosed. The oil production forecast does not anticipate any production from Block 10 in 2018

as drilling is yet to be completed.

Nickel and cobalt production at Ambatovy in 2018 is forecasted at between 40,000 tonnes and 43,000

tonnes and 3,900 tonnes and 4,200 tonnes, respectively, on a 100% basis. Forecasted production takes

into account the impact that the recent Tropical Cycl one Ava has had on operations. Production at

Ambatovy is currently halted and it is anticipated that, pending completion of repairs and replacement of

certain equipment, production will resume by the end of January. It is also expected that Ambatovy will

require a ramp up period in the first quarter of 2018 before production is stabilized.

The Power Unit is forecasted to produce between 750 and 800 megawatt hours of electricity in 2018. The

total is below 2017 production results due to natural oil reservoir declines and the resulting reduction of

gas production available for power generation.

Summary of 2018 Unit Cost Forecasts

Unit Operating Costs 2018

Guidance

Metals (NDCC, US$ per pound)

Moa Joint Venture US$2.50 - $3.00

Ambatovy Joint Venture US$3.00 - $3.50

Oil and Gas – Cuba (unit operating costs, C$ per barrel) C$22.00 - $23.50

Power (unit operating costs, C$ per MWh) C$20.75 - $21.50

Net direct cash costs (NDCC) at the Moa JV are forecasted at between $2.50 and $3.0 0 per pound of

finished nickel produced. The forecast for 2018 is marginally higher than NDCC realized in 2017 due to

increased input costs. Net direct cash costs are based on by -product credits and input commodities that

are subject to considerable change given the volatility of cobalt, fertilizers, crude oil, natural gas and

sulphur prices . The NDCC forecast for the Moa JV is also subject to the seasonality of fertilizer sales,

which are typically higher in the second and fourth quarters.

NDCC at the Ambatovy JV are forecasted at between $3.00 and $3.50 per pound of finished nickel

produced. The forecast is below the NDCC realized in 2017 due to expected increased production of

nickel and higher byproduct credits offset by higher input commodity prices, particularly sulphur.

Oil production costs in Cuba a re forecasted to be between C$22.00 and C$23 .50 per barrel . The

forecasted costs are higher than hi storical averages due to lower anticipated production in 2018 than in

previous years.

Operating costs for Power are forecasted to be between C$20.75 and C$21.50, in line with recent

performance.

Summary of 2018 Spending Cost Forecasts

Spending on capital3 (US$ millions/ C$millions) 2018

Guidance

Metals

Moa Joint Venture (50% basis) and Fort Site (100% basis) US$41 (C$52)

Ambatovy Joint Venture (12% basis) US$13 (C$17)

Oil and Gas – Cuba US39 (C$50)

Power (331/3% basis). US$1 (C$1)

Capital spending at the Moa JV is forecasted at $41 million in 2018, up significantly from 2017 . The

increase is largely due to the carry forward of unspent cap ital on activities and purchase of equipment

deferred to 2018. Capital spending in 2018 is also planned for the replacement of aging trucks and

infrastructure, including a fertilizer conveyor and a demineralized water system.

Capital spending at the Ambatovy JV is forecasted at $13 million. Spending planned for 2018 includes

projects to improve equipment reliability and address corrosion issues as well as for process improvement

projects to support the production ramp up.

Capital spending at the Oil and Gas Unit is forecasted at $39 million. The forecasted spend is primarily for

drilling activities on Block 10 and conducting a seismic program on Block 8A. The timing and amounts of

capital spending within the Oil and Gas Unit will vary depending on the collection of overdue receivables.
