Cuba's state-owned Minera de Occidente mining company announced agreements to supply Spanish and Brazilian firms with calcium carbonate and zeolites.

Starting in July, Winperas, a joint venture of Minera and Spain's Winkler Panamericana, will receive 400 tons a month of calcium carbonate from Minera for distribution in Cuba.

Winperas has been selling Spanish-produced calcium carbonate in Cuba and the substitution of the Cuban-sourced mineral will save the island $4 million a year, Minera de Occidente executive Rolando Tapanes told Efe.
