Acacia designing new tailings facility at Tanzania mine to prevent spillage
Gold miner Acacia Mining has assured its shareholders that it is working on a solution to prevent any seepage from its tailings storage facility (TSF) at the North Mara mine, in Tanzania.
The company said this month that the government of Tanzania had directed the mine to resolve a spillage of water at its polishing pond, which the company said had since been resolved.
The spillage resulted from a security incident in which sections of the pipe used to transport water from the polishing pond to the TSF had either been vandalised or stolen.
The pump used to transport water to the TSF had to be switched off, which led to the water level in the polishing pond overflowing.
Acacia said it welcomed the support of the Tanzanian government in resolving this issue and said it was working closely with the authorities to implement improvements to security measures around the polishing pond to help prevent any reoccurrence.
The miner further highlighted that the mine’s technical team was working with government to address its concerns in an agreed timeframe.
The mine has, subsequently, undertaken to manage all seepage through the use of additional pumps and the construction of other containment facilities to return any seepage to the TSF and ensure it is confined to the mine site.
Risk of ContaminationAll seepage would be contained on the site and would not flow into the surrounding environment or present a risk of contamination to any public water source, Acacia said.
In January, the Tanzanian government issued a directive to the mine to build a new TSF. Since receiving the directive, the mine has started planning and designing a new TSF and is working with government to progress the construction of the new TSF to support its future mine production plans.
Operations at the mine remain unaffected.
