Firestone to delist, trim board on tough diamond market

The operation would be second biggest diamond mine in Sierra Leone.

Shares in the diamond miner fell for a second consecutive day after it warned that two of its South african mines had been affected by strikes.

Finding follows the recovery of five other diamonds of over 100 carats so far this year at the company's flagship Letšeng mine, in Lesotho.

Initiative seeks contributing to global efforts in preventing the use of child and forced labour in the mining supply chain, and to providing information needed to demonstrate the responsible sourcing of minerals and metals.

The Africa-focused diamond miner said that would likely happen unless it solves its issues with the government of Tanzania.

Draft bill gives government first option to buy unusually large diamonds found in the country's mines, such as the world's second-biggest 1,109 carat diamond discovered by Lucara two years ago.

He joined the company's board in September 2011 and was appointed chief financial officer in April 2013.

International watchdog group Global Witness says political elites and security forces have controlled and secretly exploited Zimbabwe's diamond sector for over a decade.

The diamond miner also had to halt operations at its Williamson mine as several key employees are being questioned by local authorities.
