Sherritt Reports Strong 2022 Production Results and Provides 2023 Guidance

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

Sherritt International Corporation ("Sherritt") (TSX:S), a world leader in the mining and hydrometallurgical refining of nickel and cobalt from lateritic ores, today announced production results for the fourth quarter and year ended December 31, 2022, and provided guidance for expected production, unit costs and spending on capital in 2023.

"In 2022 we established and strengthened our core pillars to enable success in 2023 and beyond. We continued to focus on improving production efficiencies, investing in production expansion, deleveraging the balance sheet and collecting on receivables from our Cuban partners. This will enable us to take advantage of the strong long-term market fundamentals for nickel and cobalt, primarily on the strength of the electric vehicle battery market. Despite economic challenges in Cuba and global geo-political constraints, Sherritt achieved strong 2022 production results," said Leon Binedell, President and CEO of Sherritt International Corporation.

Mr. Binedell continued, "We view 2023 as a transition year for the Moa Joint Venture as we continue to deliver our plant capacity expansion and access new mining areas as we implement our updated Life of Mine plan utilizing Economic Cut-Off Grade methodology. The updated Life of Mine plan will be reflected in the revised NI 43-101 report expected in the first quarter and is expected to extend the current operations to beyond 2040."

Highlights

2022 Actual

• At the Moa Joint Venture (Moa JV) finished nickel production was 32,268 tonnes (100% basis), in line with guidance, representing a 3% increase year-over-year primarily due to increased refinery reliability and higher nickel-to-cobalt ratio, while finished cobalt production of 3,368 tonnes (100% basis) was materially within guidance.
• Power production was 568 gigawatts (GWh) of electricity, beating updated guidance as a result of successful efforts to increase gas availability.

2023 Guidance

• 2023 will be a transition year for the Moa JV. The key priority will be to ensure the expansion plan remains on time and on budget. The final draft of the NI 43-101 report is expected to be released by the end of the first quarter using the latest methodologies for the analysis of the Economic Cut-Off Grade (ECOG) and Life of Mine (LOM), in which the current LOM is expected to extend to beyond 2040. This transition phase of mine expansion will include accessing new mining areas and bringing the new slurry preparation plant (SPP) online in 2024. As a result, finished nickel production is forecast to be 30,000 – 32,000 tonnes (100% basis), while finished cobalt production is forecast to be 3,100 – 3,400 tonnes (100% basis).
• Net direct cash costs (NDCC) ¹ at the Moa JV are forecast to be in the range of US$5.00 - US$5.50 per pound of finished nickel sold.
• Sherritt's share of spending on capital ¹ is forecast to be C$94.4 million:
  • Sustaining spending on capital of C$70 million is primarily for infrastructure, the replacement of equipment, and tailings management at the Moa JV.
  • Growth spending on capital of C$20 million is primarily for the continued construction of the new SPP and leach plant sixth train at the Moa JV.
  • Sustaining spending on capital of C$4.4 million at Power is primarily for maintenance and equipment purchases.

Summary of 2022 Production Results

Sherritt expects to report its full operational and financial results for the fourth quarter and year ended December 31, 2022 on February 8, 2023 after market close.

2023 Guidance

Guidance for 2023 is based on a number of assumptions and estimates as of January 23, 2023 including, among other items, assumptions about commodity prices, prevailing currency exchange rates, and anticipated costs and expenditures. Sherritt's guidance for 2023 also includes estimates based on several risks and uncertainties, which may cause actual results to differ materially.

Summary of 2023 Production Forecasts

Moa JV production guidance is slightly lower in 2023 compared to guidance figures provided in previous years as the Moa JV transitions towards its expansion plan commencing in 2024 and reduces reliance on low margin third-party feed. Additionally, the transition to the new SPP will cause some temporary processing disruptions as Moa JV relies solely on the old SPP.

The Power business is expected to produce between 575 and 625 GWh of electricity in 2023, higher than previous year's guidance, as Sherritt continues to work with its Cuban partners to increase the availability of gas.

Summary of 2023 Unit Operating Cost Forecasts

NDCC at the Moa JV are forecast between US$5.00 and US$5.50 per pound of finished nickel sold, above guidance for 2022, due to lower forecast cobalt and net fertilizer by-product credits. NDCC for the year to date Q3 2022 was US$4.39 ⁴ per pound of nickel sold. NDCC includes by-product credits and input commodities that are subject to considerable change given the volatility of cobalt, fertilizers, sulphur, diesel and fuel prices. NDCC guidance for 2023 is based on a forecast cobalt reference price of US$23.50 per pound and a forecast sulphur price of US$230 per tonne including freight and handling.

Forecasted NDCC will have some quarterly variance due to the seasonality of fertilizer sales, which are typically higher in the second and fourth quarters, and planned maintenance shutdowns.

Unit operating costs for the Power business in 2023 are forecast to be between C$28.50 and C$30.00 per MWh. Unit operating costs for 2023 are expected to be above guidance for 2022 due to planned gas and steam turbine maintenance in preparation for additional gas supply in late 2023. Power unit operating costs for the year to date Q3 2022 was C$18.60 ⁴ .

Summary of 2023 Spending on Capital Cost Forecasts

Sherritt's share of spending on capital at the Moa JV and Fort Site is forecast at C$90 million in 2023. Sustaining spending on capital of C$70 million is primarily for infrastructure, the replacement of equipment, and tailings management at the Moa JV. Sustaining spending on capital for the year to date Q3 2022 was C$44.4 million ⁴ .

Forecast growth spending on capital for 2023 of C$20 million is primarily for the continued construction of the new SPP and leach plant sixth train. Growth spending on capital in year-to-date Q3 2022 was C$3 million ⁴ .

During 2022, Sherritt approved a two-phase expansion project focused on increasing annual mixed sulphate precipitate (MSP) production by 20% of current production or 6,500 tonnes of additional contained nickel and cobalt (100% basis). The expansion program capitalizes on the growing demand for high purity nickel and cobalt being driven by the accelerated adoption of electric vehicles and builds on the 26-year successful track record of the Moa JV. Total capital cost is estimated to be US$77.0 million (100% basis) or approximately US$13,200 per additional annual tonne of contained nickel for the full expansion.

Non-GAAP and Other Financial Measures

Unit operating cost/net direct cash cost (NDCC) and spending on capital are non-GAAP measures. Management uses these measures to monitor the financial performance of the Moa JV, Power and other operating divisions. Management believes these measures enable investors and analysts to compare the Corporation's financial performance with its competitors and/or evaluate the results of its underlying operations. These measures are intended to provide additional information, not to replace International Financial Reporting Standards (IFRS) measures, and do not have a standard definition under IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. As these measures do not have a standardized meaning, they may not be comparable to similar measures provided by other companies.

Historical unit operating cost/net direct cash cost (NDCC) and spending on capital are incorporated by reference to Sherritt's Q3 2022 Management Discussion and Analysis for the three and nine months ended September 30, 2022, dated November 2, 2022, which is available on Sherritt's website. Unit operating cost and net direct cash cost amounts have been reconciled to their most directly comparable IFRS measures in the Non-GAAP and other financial measures section of the MD&A starting on page 38.
