Savannah Resources said on Wednesday it had little control over what it described as the political process which is delaying its extraction plans for what could become western Europe's largest lithium mine in northern Portugal.
Portugal is already Europe's biggest lithium producer, but its miners sell almost exclusively to the ceramics industry and are only now preparing to produce the higher-grade lithium that is in demand globally for use in electric cars and electronic devices.
London-based Savannah has said Portugal's Barroso mine could be at the centre of Europe's lithium value chain.
