Sherritt's Updated Reserve Estimate and Life of Mine Plan at the Moa JV More than Doubles Reserves and Extends Life of Mine to 26 years

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

Sherritt International Corporation ("Sherritt", the "Corporation") (TSX:S), a world leader in the mining and refining of nickel and cobalt metals essential for the growing adoption of electric vehicles, announced today that it is filing an updated National Instrument 43-101 Technical Report (NI 43-101 or 2023 Moa JV Technical Report) for the Moa Joint Venture (the Moa JV) indicating that current reserves are expected to support a 26 year life of mine.

Highlights

  • Proven and Probable Reserves (i) increased to 1,182 kt of nickel and 144 kt of cobalt, an increase of 110% and 129% (ii) , respectively;
  • The life of mine (LOM) extends to 2048, an increase of 14 years, with total estimated metal recovered of 724 kt of nickel and 85 kt of cobalt;
  • Over the next 10 years, average annual finished metal production of 30 kt of nickel and 3.3 kt of cobalt from Moa is expected, excluding the impact of the Moa JV expansion program and refining of third-party feeds;
  • Favourable economics in the base case scenario supports an after-tax NPV (8%) of US$812 million (100% basis) using conservative prices of US$7.12/lb nickel and US$21.32/lb cobalt;
  • Significant upside in an alternative case increases the after-tax NPV (8%) to US$1.5 billion (100% basis) using recent analyst commodity price forecasts of US$9.00/lb nickel, US$23.50/lb cobalt and higher input commodity prices;
  • The 2023 Moa JV Technical Report excludes the upside NPV impact from the Moa JV expansion. Once completed by the end of 2024, the full expansion is expected to result in a higher NPV but shorten the LOM by 3-5 years.

"The updated reserves and associated life of mine at the Moa JV underpins and validates our long-term strategy for producing low cost, high purity nickel and cobalt," said Leon Binedell, President and CEO of Sherritt International. "With an estimated 26-year mine life and a strong market outlook for our products, the revised economics supports both our near-term strategy of expanding production capacity and our long-term growth ambitions to meet the demand from evolving markets increasingly driven by the energy transition and, in particular, electric vehicle battery supply chains."

Mineral Reserve Estimates

The 2023 Moa JV Technical Report, which incorporates a newly developed strategic LOM plan based on the economic cut-off grade (ECOG) methodology, estimates that as of August 31, 2022 the Moa JV had 117.2 millions of tonnes (Mt) of proven and probable reserves at an average nickel grade of 1.01% and cobalt grade of 0.12%, providing total reserves of 1,182 kt of contained nickel and 144 kt of contained cobalt. The updated contained nickel and cobalt reserves are 110% and 129% higher, respectively, compared to the amounts previously reported and as disclosed in the 2021 Annual Information Form (2021 AIF).

Updated Life of Mine Plan

With the increase in Proven and Probable Reserve estimates, Moa's mine life is expected to extend by approximately 14 years to 2048 based on the utilization rates at the effective date of the 2023 Moa JV Technical Report. Over the next 10 years, average annual finished nickel and cobalt production, exclusive of the impact of the current expansion program and third-party feed, is estimated at 30 kt of finished nickel and 3.3 kt of finished cobalt. Total recovered metals over the extended life of mine are estimated to be 724 kt of nickel and 85 kt of cobalt.

The current LOM strategy used to support the 2023 Moa JV Technical Report uses an "economic cut-off grade" (ECOG) methodology versus a "fixed cut-off grade" (FCOG) used in the previous NI 43-101 Technical Report filed June 26, 2019 for the Moa JV in determining the amounts of Proven and Probable reserves. The primary difference between the ECOG and FCOG is that the ECOG better reflects the potential economic benefit of extracting the selected material. The ECOG definition incorporates the nickel and cobalt commodity prices, the metallurgical recovery of these metals, and the costs involved in the mining, refining and marketing of these metals.

Economic Analysis

The base case extended LOM has a favourable after tax NPV of US$812 million (100% basis) at an 8% discount rate using conservative prices of US$7.12/lb nickel and US$21.32/lb cobalt. This is based on the LOM in the 2023 Moa JV Technical Report.

Additionally, the 2023 Moa JV Technical Report includes an alternative scenario which results in an after tax NPV of US$1.5 billion (100% basis) at an 8% discount rate, based on recent analyst commodity price forecasts for nickel, cobalt and key input commodity prices.

  2. The economic analysis including the NPV calculation is for the Moa JV and production from the Moa mine only and does not consider the impact of operating results of Sherritt's 100% owned fertilizer business, potential third-party feed opportunities, and the impact of the current Moa JV expansion on timing of production and capital cost estimates.
  3. In addition to the nickel and cobalt prices in the table, key input commodity prices for the base case and alternative scenario include: sulphur – US$161/t and US$230/t, diesel – US$0.64/l and US$1.00/l, and fuel oil – US$320/t and US$500/t, respectively.

Impact of Current Moa JV Expansion Program on the LOM

In 2021, the Moa JV embarked on a low capital intensity expansion program to capitalize on the growing demand for high purity nickel and cobalt being driven by the accelerated adoption of electric vehicles (EV). The scope of the expansion program was narrowed during 2022 to better reflect the evolving intermediate market for nickel and cobalt and to focus on the most critical components of growth in light of supply chain challenges and inflationary price pressures on capital. The current program is aimed at increasing annual mixed sulphide precipitate (MSP) production by 20% or 6,500 t of contained nickel and cobalt (100% basis).

The expansion program consists of two phases with phase one focused on the construction of a new slurry preparation plant (NSPP) at Moa, and phase two is focused on the expansion of the Moa processing plant, including the Leach Plant Sixth Train and Fifth Sulphide Precipitation Train as well as construction of additional acid storage capacity at Moa. The total capital cost is expected to be US$77 million (100% basis) or approximately US$13,200 per additional annual tonne of contained nickel for the full expansion. Growth spending on capital for the expansion program is expected to be self-funded by the Moa JV primarily using operating cash flows.

The economic analysis in the 2023 Moa JV Technical Report includes the remaining capital for the construction of the NSPP and the related ore haulage distance and mining fleet benefits; however, it does not include any of the incremental MSP production associated with that phase. Therefore, Sherritt estimates only US$50 million of additional capital would be required to complete the expansion program and realize the increased annual production of MSP by 6,500t of nickel and cobalt and associated economic benefits.

Assuming an accelerated mining sequence in order to meet the expected increased production related to the Moa JV expansion, the LOM would likely be reduced by 3 to 5 years, resulting in a LOM of approximately 21 to 23 years. This increased production would be expected to increase cashflows and the NPV of the Moa JV.

APPENDIX 1 – RESOURCE AND RESERVE DEFINITIONS

Mineral resource and mineral reserve definitions, according to the "CIM Standards on Mineral Resources and Reserves – Definitions and Guidelines", are as follows.

MINERAL RESOURCE

A ‘Mineral Resource' is a concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling.

An ‘Inferred Mineral Resource' is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity.

An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

An ‘Indicated Mineral Resource' is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.

Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation.

An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Mineral Reserve.

A ‘Measured Mineral Resource' is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit.

Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation.

A Measured Mineral Resource has a higher level of confidence than that applying to either and Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proven Mineral Reserve or to a Probable Mineral Reserve.

Modifying Factors are considerations used to convert Mineral Resources to Mineral Reserves. These include, but are not restricted to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors.

MINERAL RESERVE

A ‘Mineral Reserve' is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Pre-Feasibility or Feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified.

The reference point at which Mineral Reserves are defined, usually the point where the ore is delivered to the processing plant, must be stated. It is important that, in all situations where the reference point is different, such as for a saleable product, a clarifying statement is included to ensure that the reader is fully informed as to what is being reported.

The public disclosure of a Mineral Reserve must be demonstrated by a Pre-Feasibility Study or Feasibility Study.

A ‘Probable Mineral Reserve' is the economically mineable part of an Indicated, and in some circumstances, a Measured Mineral Resource. The confidence in the Modifying Factors applying to a Probable Mineral Reserve is lower than that applying to a Proven Mineral Reserve.

A ‘Proven Mineral Reserve' is the economically mineable part of a Measured Mineral Resource. A Proven Mineral Reserve implies a high degree of confidence in the Modifying Factors.

Notes:

  1. Mineral Reserves are reported with an effective date of 31 August 2022, using the 2014 CIM Definition Standards.
  2. The Qualified Person for the estimate is Michiel Breed, a Micon employee.
  3. Mineral Reserves are reported on a 100% basis. Sherritt and GNC are equal (50:50) partners in the Moa JV Moa Project.
  4. The reporting cut-off is calculated as a Net Value = Revenue from Ni + Revenue from Co – Cost >0, and Ni>=0.7% and Fe>=25%. The costs are equal to the sum of mining costs, processing costs and nickel selling cost of US$2.00/lb, including Moa port and loading, freight and insurance, CRC refining and royalties. The processing cost has a fixed component of US$69.76/t and a variable cost related to Fe, Mg and Al content. Revenue was calculated at the market price of US$7.1/lb for nickel and US$21.3/lb for cobalt, with nickel and cobalt MSP to Product recovery of 98.2% and 92%, respectively. SPP to MSP nickel and cobalt recovery is variable and depends on iron content. Mineral Reserves include a 15% allocation for ore loss and a 5% dilution factor.
  5. The Mineral Reserves volume and tonnage have been rounded to reflect the accuracy of the estimate, and numbers may not add up due to rounding.

Notes:

  1. Mineral Resources are reported in situ, with an effective date of 31st August 2022, using the 2014 CIM Definition Standards.
  2. The Qualified Person for the estimate is Ms Beatrice Foret, MAusIMM (CP), a Micon employee.
  3. Mineral Resources are reported inclusive of those Mineral Resources converted to Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
  4. Mineral Resources are reported on a 100% basis. Sherritt and GNC are equal (50:50) partners in the Moa JV Moa Project.
  5. The reporting cut-off is calculated as a Net Value = Revenue from Ni + Revenue from Co – Cost >0, and Ni>=0.7% and Fe>=25%. The costs are equal to the sum of mining costs, processing costs and nickel selling cost of US$2.00/lb, including Moa port and loading, freight and insurance, CRC refining and royalties. The processing cost has a fixed component of US$69.76/t and a variable cost related to Fe, Mg and Al content. Revenue was calculated at the market price of US$9.7/lb for nickel and US$28.1/lb for cobalt, with nickel and cobalt MSP to Product recovery of 98.2% and 92%, respectively. SPP to MSP nickel and cobalt recovery is variable and depends on iron content. The cut-off grade for the estimated Mineral Resource is based on similar mining operations in other countries and reasonable assumptions on mining and processing.
  6. No stockpiled material is included in the Mineral Resources.
  7. The block model grades were estimated using the ordinary kriging method.
  8. The Mineral Resources volumes and tonnages have been rounded to reflect the accuracy of the estimate, and numbers may not add up due to rounding.
