MIDAS VERDICT:

Lithium is a metal whose time has come. Savannah Resources has one of the most exciting mines in Europe, that could be up and running within three years. At 4.2p, the shares have been held back by concerns the Portuguese government will refuse to let Savannah move into construction. But there are strong grounds for optimism and, if all goes well, the stock could deliver substantial rewards. An attractive buy for adventurous investors.
