Jamalco is a joint venture between General Alumina Jamaica Limited (a subsidiary of Century Aluminum Company) and Clarendon Alumina Production Limited (a wholly owned Government company) with a focus on bauxite mining and alumina production. Jamalco started as a bauxite mining venture by Alcoa in 1959 and exported its first shipment of bauxite in 1963. The venture began alumina production at a new refinery in Halse Hall, Clarendon in 1972 with a production capacity of 500,000 metric tonnes per year (mtpy), which it exported from its port facility at Rocky Point. The refinery’s capacity was upgraded to 1 million mtpy in 1999 and then to 1.25 million mtpy in 2003. The last expansion was in 2007 to 1,416,700 mtpy. In May 2023, Century Aluminum Company acquired General Alumina Jamaica Limited, which owns 55 percent of the joint venture and Clarendon Alumina Production Limited retains its 45 percent ownership of the joint venture. What We Do: Jamalco mines bauxite and refines it into alumina before it is exported from its Port at Rocky Point, Clarendon. Jamalco’s bauxite mines are located in South Manchester on the Mount Oliphant plateau and in Harmons Valley in Jamaica. The railhead from which bauxite is trammed to the refinery is located at St. Jago in Clarendon, Jamaica. The refinery is located at Halse Hall in Clarendon, Jamaica and the Port from which alumina is shipped is located at Rocky Point also in Clarendon, Jamaica.

About Jamalco
Jamalco is a renowned brand in the mining and production industry, specializing in bauxite mining and alumina production. Established in 1959 as a joint venture between General Alumina Jamaica Limited and Clarendon Alumina Production Limited (CAP), Jamalco has a rich history and expertise in the field. Their journey began with bauxite mining, and in 1963, they successfully exported their first shipment of bauxite.
Over the years, Jamalco expanded its capabilities and started alumina production in 1972 at a refinery in Halse Hall, Clarendon. With continuous upgrades, the refinery's production capacity reached an impressive 1,416,700 million metric tonnes per year. Jamalco's ownership structure has evolved, with Alcoa initially managing the joint venture.
However, in December 2014, global commodities company Noble Group acquired Alcoa's stake, while CAP retains its 45 percent ownership. As part of their operations, Jamalco mines bauxite and refines it into alumina. On average, it takes 2.
5 tonnes of bauxite to produce one tonne of alumina. The alumina is then exported to aluminium smelters, where it plays a vital role in producing one tonne of aluminium metal. Jamalco's mining sites are strategically located in South Manchester and Harmons Valley, while their refinery is situated in Halse Hall.
They have a dedicated port at Rocky Point for the shipment of alumina. Driven by their commitment to excellence, Jamalco aims to be recognized as The Best Alumina Producer. They continually strive for improvement in all aspects, including delivering world-class alumina, exceeding customer expectations, maintaining cost-effectiveness, and ensuring safety, environmental sustainability, and social responsibility.
