Barrick brings TSF back within design capacity

Late last year Barrick Gold managed to bring the North Mara gold mine’s tailings storage facility (TSF) pond back within its permitted design capacity.

Barrick made a commitment to the Tanzanian government when it took over control of the mine in September 2019, at a time when the country’s National Environment Management Council (NEMC) had closed down the TSF, then holding significantly more water than it should.

The company’s chief operating officer for Africa and the Middle East, Willem Jacobs, describes the achievement of the target as a huge milestone for North Mara and its team, who had made a herculean effort to bring the badly neglected TSF into line with international best practice as well as Barrick’s own tailings management standards.

Barrick spent more than USD65-million on the project, increasing the water treatment plant’s capacity 16-fold from 2.5 million litres per day to 40 million litres per day. The addition of a brine treatment plant has reduced the volume of salts in the effluent water, enabling it to be stored safely.

Jacobs says that the mine will continue to monitor the TSF’s performance and will engage regularly with the relevant authorities to ensure that its high standards are maintained. “This includes the analysis of drinking water wells and surface water sources surrounding the mine,” says Jacobs.

“When we took over the old Acacia assets in Tanzania, we formed a partnership with the government to oversee these mines. The real benefits of this partnership included the swift resumption of operations at North Mara and the revitalisation of the moribund Bulyanhulu, now both valuable members of the Barrick portfolio. This latest development is further proof of our partnership philosophy’s capacity to deliver real benefits and our commitment to caring for the welfare and environment of our host communities,” says Jacobs.
