Sherritt Moa Nickel-Cobalt Pause Raises New Supply Concerns for 2026

Sherritt International

Sherritt Moa nickel-cobalt pause is now the company’s most immediate operational challenge for 2026. Sherritt said it will temporarily suspend mining at its Moa joint venture in Cuba because fuel deliveries cannot be fulfilled. The company also expects to place the processing plant on standby. As a result, Sherritt Moa nickel-cobalt pause is creating new uncertainty around upstream supply and production planning.

This matters because Moa is a key source of nickel and cobalt feed for Sherritt’s wider business. The company said it does not yet know when fuel deliveries to the site will resume. That makes the interruption more serious than a short maintenance event. Therefore, Cuba nickel-cobalt supply is now facing a disruption with no clear restart timeline.

Sherritt is using the downtime to complete maintenance activities at the processing plant. That should help the site use the pause more productively while operations remain constrained. However, the core issue is still fuel access, not plant readiness. Consequently, Sherritt Moa nickel-cobalt pause may last longer than the market would prefer.

Fort Saskatchewan Refinery Buys Some Time

Fort Saskatchewan refinery gives Sherritt some short-term protection against the Cuban disruption. The company said its Alberta refinery should see no immediate impact and will continue producing finished nickel and cobalt. Existing feed inventory is expected to last until mid-April. As a result, downstream production can continue for now.

That inventory buffer is important, but it is limited. If Moa mining and processing do not restart before the feed runs low, pressure could move downstream as well. Therefore, the Fort Saskatchewan refinery is buying time rather than fully solving the problem.

Nickel and Cobalt Output Guidance Now Looks Less Certain

Nickel and cobalt output guidance for 2026 now looks harder to defend. Sherritt had expected to produce 26,000-28,000t of finished nickel and 2,750-2,850t of finished cobalt this year. The company now says it will update guidance once it has greater certainty on a full restart. As a result, Sherritt Moa nickel-cobalt pause is directly affecting market expectations for annual output.

One part of the business remains stable. Sherritt said its power division, Energas, should continue operating without issues. That limits the disruption to the metals side of the portfolio. Meanwhile, investors and buyers will focus on how quickly fuel deliveries can return to Moa.

The Metalnomist Commentary

This disruption shows how vulnerable nickel and cobalt supply chains can remain to non-market factors such as fuel availability. Sherritt still has some downstream breathing room, but that buffer is not large. If Moa stays offline for too long, the company may need to materially reset its 2026 metals outlook.
