Operations at Shanta Gold's New Luika mine in south-west Tanzania were hit by a "fire incident" this week, though the company assured that it will have no impact on production.The East Africa-focused gold miner said that there was a fire in the screening section of the recently-commissioned crushing circuit of the gold processing plant at New Luika on Thursday.Two people suffered minor injuries but returned to work later in the shift. The rest of the plant was not affected."Whilst repairs are being undertaken there is expected to be no impact on this quarter's gold production as the company is able to revert back to the standby crusher," AIM-listed Shanta said in a statement.The company is investigating the cause of the incident and said it is treating the issue with the "utmost seriousness".
