Acacia Mining on Friday reported a 13% rise in gold reserves at the end of May for its Gokona mine in North Mara, Tanzania, adding weight to its view that majority shareholder Barrick Gold’s buyout proposal undervalued the miner. Acacia Mining last month strongly disagreed with the world’s No. 2 gold miner’s valuation of the company, saying the proposal undervalued its mine plans and appeared to have ignored the value of its exploration and development assets.
