Sherritt International Corp. has ceased operations at its Fort Saskatchewan refinery in Alberta, citing the exhaustion of feed inventory from its Moa mine in Cuba.
The Canadian energy firm confirmed the halt, marking a significant contraction in its North American processing capacity as the supply link to its Caribbean mining operations has been severed.
The refinery closure is the direct operational consequence of Sherritt's recent strategic withdrawal from Cuba.
The company previously announced it was shutting down its Cuban mining activities, identifying the tightening of U.S. sanctions as the decisive factor in the decision.
With the Moa mine no longer producing nickel and copper concentrate for export, the refinery in Alberta has been left without the raw material necessary to sustain production.
This development highlights the severe logistical and financial constraints facing Sherritt.
