News of a high court claim against African Barrick Gold over the deaths of Tanzanians tarnished its shares on a day when it revealed $185m of cost cuts.
The struggling mid-cap gold miner has been accused of being complicit in the killing by police of at least six villagers in Tanzania during violence at one of its mines in May 2011.
African Barrick, which said it believes these "proceedings are without merit" and that it "intends to vigorously defend its interests", has a lot on its plate and investors headed for the exit even though it set out plans to address its financial problems. The shares were marked down 5.4p to 111.4p as it revealed $727m (£475m) of write-downs.
The company has been hit by the falling gold price, and although gold has picked up again in the past month, African Barrick's shares are still down more than 75 per cent since the start of the year.
The write-downs relate to a reduction in the value of its mines after it completed an operating review this year. It has now confirmed cost-cutting plans that will include closing its Buzwagi mine in Tanzania in less than four years.
Its second-quarter results were positive, with production and costs beating market expectations. But until there are signs of improvement in profits, the City will remain unconvinced. Investec's Hunter Hillcoat rated African Barrick a hold with a 135p price target.
The FTSE 100 failed to get past the 6,600 "sticking point" that City analysts have noted as a hurdle at the moment, but it still rose 10.7 points to 6,570.95.

News that Centrica is poised to become the biggest gas supplier to America's East Coast powered it up 8p to 385.8p. The deal to buy Hess's energy marketing business for around £500m comes ahead of its first-half numbers today.
The American business will become part of Centrica's US operation, Direct Energy, making that "the largest business gas supplier on the US East Coast and second-largest business power supplier in the retail market," Liberum Capital said. The broker added that the deal means Centrica is on track to double its North American profit in the medium term. Liberum's Peter Atherton rated the group a buy but said he needed "more financial information" before deciding on the value of the deal.
