Miner Bellzone rose on Wednesday after it began a multi-million dollar share buy-back scheme.
The firm has the mandate to buy up to $3m of its stock from shareholders, equivalent to 1.6% of its issued share capital.
It will do this through market purchases of the company's own ordinary shares, with the cost based on the prevailing market price quoted on AIM.

Nik Zuks, Bellzone's Chief Executive, said the buy-back represented an opportunity to return value to shareholders while the company's shares were at very depressed levels.
"We remain well funded with $105m of cash on hand as at 31 May 2012, with [the] Forecariah [mine in Guinea] fully financed to production," he said.
