Glencore joins battle for Cuba
Glencore has joined a contest to recapitalize Sherritt International, a Canadian miner with a 50% stake in Cuba’s Moa nickel-cobalt venture, which includes the Fort Saskatchewan refinery in Alberta. After US widened Cuba sanctions in May, Sherritt withdrew, staff resigned, and it faces early repayment of a $57m loan. Glencore’s consortium proposes a US vehicle for at least 55% equity, while Gillon Capital also seeks 55% via warrants.
How this was made

The 30-second read
Why it matters
For Sherritt, expanded US sanctions and governance departures raise financing and operational risk, while competing proposals aim to recapitalise the company and secure non-Chinese refining capacity. For Glencore, the bid signals strategic positioning in cobalt/nickel refining, but execution risk remains due to sanctions and regulatory boundaries.
Market read
A sanctions-driven distress situation is now entering an active control contest, creating near-term headline risk and potential deal-driven repricing.
What to watch
Deal success may hinge on US regulatory tolerance for “working around” sanctions and on whether feedstock and cashflow can restart at Fort Saskatchewan.
Background
The article frames a control contest for Sherritt International tied to its 50% stake in the Moa nickel-cobalt JV with Cuba’s General Nickel Company, which underpins North America’s significant cobalt refining capacity.
Market effects
Highlights strategic-metals refining capacity competition and sanctions risk for cobalt/nickel supply chains.
Could affect Canadian listed mining sentiment tied to Cuba exposure and sanctions compliance.
Non-Chinese refining capacity remains a geopolitical constraint, influencing investor appetite for strategic metals infrastructure.
Counterpoint
Even with bids, sanctions constraints may prevent workable structures, making the contest more about leverage than a near-term resolution.
