Minas de Matahambre — A new lead and zinc mine in northwestern Cuba is on track to start production in October as part of the Caribbean island’s efforts to breathe fresh life in its mining sector, says the Emincar joint venture. While nickel exports are already among Cuba’s main earners of foreign currency, that cash-strapped country has untapped potential in other mineral deposits, according to the US Geological Survey. The $278m Castellanos mine would produce 100,000 tonnes of zinc concentrate and 50,000 tonnes of lead concentrate a year, said executives at Emincar, the venture between Swiss-based commodities group Trafigura and Cuban state company Geominera.
