Jamaica’s Government learned that UC Rusal might sell Windalco the same way investors did, according to a Bloomberg report citing unnamed sources. 

Mining Minister Floyd Green said that the Government had no record or notice of any sale, and that Rusal’s local team had no information either. The Government says it will query the parent. Rusal has not confirmed the report, and Bloomberg’s sources said any sale was at an early stage and might not proceed.

 But the episode points to a structural issue: every operating alumina refinery in Jamaica is majority foreign-owned, and decisions about their future are made in boardrooms abroad.

Windalco is wholly owned by Rusal of Russia. Jamalco is 55% held by US-based Century Aluminium, with the Government’s Clarendon Alumina Production holding 45%. Alpart, shut since 2019, belongs to China’s state-owned JISCO, which plans a US$490 million first-phase restart due by June 2027. Discovery Bauxite exports ore from St Ann to Atlantic Alumina’s refinery in Louisiana.

Ownership has shifted repeatedly. Rusal built control of about 65% of Jamaica’s alumina production after buying Norsk Hydro’s Alpart stake in 2011 and later agreed to sell Alpart to JISCO in 2016.

 The Government sold its last 7% of Windalco to Rusal in 2014, credited against debt it owed the company. Each change reset the counterparty the state deals with on leases, royalties and investment.

The law gives the Government a checkpoint at the asset level. Under the Mining Act, a mining lease holder cannot transfer the lease or any interest in it without the Minister’s written consent, according to the Jamaica Business Gateway. What is less clear is whether a sale of shares higher up the corporate chain, leaving the local lease holder unchanged, triggers the same requirement or any duty to notify. The bauxite agreements between the state and individual producers, which may contain change-of-control clauses, have not been made public. 

Listed parents disclose under the rules of their stock exchanges, which generally require announcements once a transaction is material and agreed, not when buyers are first approached. That timing gap means host governments may learn of early-stage talks only through press reports.

The exposure is not small. Windalco produced 396,000 tonnes of alumina in 2025, equal to about 28% of national alumina export volume. Mining and quarrying export earnings fell 46.4% in January to May 2026, according to the Statistical Institute of Jamaica.

Guyana faces the same question. Rusal holds 90% of the Bauxite Company of Guyana, with the Guyanese Government holding 10%. Bloomberg said that the operation is also being marketed.

Green has pointed to Windalco’s recently completed US$29 million haul road and a new mining area as signs that operations are continuing. The Government has not said whether it will seek notification terms in future mining agreements.
