The operational halt at the Moa joint venture follows a period of mounting supply chain volatility. According to a company statement, Sherritt is unable to secure fuel on a reliable schedule, forcing the decision to pause active mining. While the facility remains on standby, the company plans to redirect its workforce toward essential maintenance activities to ensure the plant remains viable for an eventual restart.

Sanctions and Economic Impact

The energy crisis is largely a byproduct of tightened U.S. sanctions, which have restricted oil shipments to the island and left the national grid in a state of near-collapse. This shortage has already forced the Cuban government to implement rolling blackouts and cancel commercial flights. The United Nations has described the deteriorating conditions as a humanitarian crisis, noting that the lack of fuel is impacting basic services such as water distribution and healthcare.

Sherritt is currently "evaluating all options" for sourcing the input commodities necessary to resume production. However, the company has not provided a specific date for when it expects to return to full capacity. The pause marks a significant disruption for one of Cuba's most vital industrial partnerships as the country struggles to navigate its most restrictive energy environment in decades.
