STOCK WATCH

INVESTORS in troubled gold miner Acacia Mining enjoyed a session in the black.

Acacia has been at loggerheads with the government of Tanzania over the latter’s decision to ban the export of gold concentrate. Earlier this week, the firm was served a £138bn fine by the government for allegedly undervaluing its gold in the country.

But Acacia shot up yesterday after saying discussions with the government were under way. Shares increased 13.1pc, or 20.7p, to 178.5p.
