Five years after its formation, the Twiga partnership between Barrick Mining Corporation and the government of Tanzania continues to deliver shared value and operational excellence. Since Barrick took operational control in 2019, it has injected $4.79 billion into the Tanzanian economy, including $558 million in the first half of 2025. 

More than 90% of procurement continues to be with Tanzanian suppliers, the majority of whom are indigenous companies, with 96% of the workforce being Tanzanian and 49% coming from communities around the mines.

Barrick’s Tanzanian mines continue to deliver in line with guidance.  At the Bulyanhulu gold mine development of the Upper West decline is well advanced, supported by the arrival of a new fleet and improved access through expanded infrastructure.  The mine has benefited from focused investment in ventilation and dewatering systems.  These improvements are unlocking bottlenecks, improving flexibility and positioning Bulyanhulu to produce gold for decades.

At North Mara, a newly commissioned battery energy storage system is addressing power reliability, while underground and open-pit mining are progressing according to plan.  Community resettlement activities are nearing completion, and the mine continues to build trust and its social license.

Barrick president and chief executive Mark Bristow said the partnership had created a sustainable model for mineral development in Tanzania. “When we established Twiga, it was about more than just resolving legacy issues.  It was about building a new future by unlocking Tanzania’s gold endowment in a way that fairly shares the benefits and builds lasting value for all stakeholders.  Five years on, we’ve not only re-established Barrick as the sector’s leading economic contributor but have also earned national recognition across a range of areas from safety and local content to education and infrastructure.”
