Sherritt and its Cuban partners are finalizing timelines, cost estimates and economics of other components of the growth strategy, including identifying financing alternatives. Sherritt currently estimates the growth strategy will deliver incremental increases to annual finished nickel and cobalt production by 15 to 20% from totals produced in 2021 once all projects at Moa, including the SPP and the refinery in Fort Saskatchewan, are completed in 2024 at an anticipated cost of US$20,000 to US$25,000 per tonne of new nickel capacity. Sherritt expects to provide further updates on its growth strategy with the release of its results for the first quarter of 2022.
