OWNERS of gold processing plants using Carbon-in-Pulp (CIP) technology in Geita Region have been instructed to ensure proper management of their tailings and chemical waste ponds, especially during the ongoing rainy season to prevent leaks that could harm nearby communities.

They have also been urged to implement effective water management systems within their operations to maintain the structural integrity of pond walls and avoid overflow that could endanger surrounding residents.

The directive was issued recently by Samwel Shoo, Geita Regional Mining Officer, who warned that the current rains pose a serious risk if proper safety measures are not in place.

Shoo emphasized the importance of surrounding all processing sites with trenches connected to drainage pits to prevent rainwater from flowing into or out of the project areas unchecked.

He also cautioned plant owners to avoid overfilling chemical mixing pits and to ensure that leaching tanks are not excessively loaded with soil, which could cause spillage.

“The Mining Commission has received a weather forecast from the Ministry of Minerals indicating ongoing long rains from March through May. The rains can significantly disrupt mining and processing activities and pose serious risks to nearby communities,” he said.

In response, the commission has begun reinforcing embankments and constructing extended drainage systems at small-scale mining sites to control rainwater infiltration.

Shoo stressed that all mines must maintain strict safety protocols, including daily monitoring of weather reports from the Tanzania Meteorological Authority and the evacuation of workers from pits at the first signs of heavy rain.

He urged miners to work with heightened caution during this rainy season and to ensure that their mining infrastructure is well-constructed to prevent accidents and safeguard workers.
