Gold has long powered Tanzania’s mining economy, but the story of Barrick Gold Corporation in the country is less about geology and more about transformation. What was once a strained and uncertain operating environment has evolved into one of Africa’s most closely watched examples of how governments and mining companies can rebuild trust and unlock value together.
At the centre of this shift is Twiga Minerals Corporation, the joint venture formed in 2019 between Barrick and the Tanzanian government. More than just a corporate restructuring, Twiga reset the relationship between state and investor, turning a period of conflict into a framework for collaboration. It gave the government a direct stake in the country’s gold assets, aligned economic interests and created a pathway for operations to stabilise and grow again. Before this shift, Barrick’s Tanzanian assets then operated under Acacia Mining had been caught in a prolonged dispute over taxes, exports and regulatory compliance. The fallout disrupted production, shook investor confidence and left key mines underperforming. The creation of Twiga marked a decisive break from that past, allowing Barrick to regain operational control and reintroduce long-term planning.
Today, the company’s presence in Tanzania is anchored by two major operations, Bulyanhulu Gold Mine and North Mara Gold Mine. Together, they form a Tier One gold complex producing more than half a million ounces of gold annually. But beyond production figures, what stands out is how these mines have been repositioned from struggling assets into consistent performers. At Bulyanhulu, a technically complex underground mine, operations were successfully restarted after a period of suspension, supported by renewed investment in infrastructure and systems. North Mara, combining open-pit and underground mining, has seen steady improvements in efficiency and output. Both operations now reflect a level of operational discipline that was missing during earlier years of uncertainty.
Since 2019, Barrick’s economic footprint in Tanzania has grown significantly. Billions of dollars have been injected into the local economy through taxes, procurement and investment, with a strong emphasis on sourcing goods and services locally. This shift has helped stimulate domestic supply chains and support the growth of Tanzanian businesses linked to the mining sector. Employment has followed a similar pattern. The workforce numbers in the thousands, with the overwhelming majority being Tanzanian nationals and a significant portion drawn directly from surrounding communities. This focus on local participation is not just about numbers, it is part of a broader effort to embed mining more deeply into the national economy rather than operating as an isolated enclave industry.
The Twiga model itself has gained attention across the continent. By giving the government a meaningful stake and ensuring a clearer sharing of benefits, it has helped restore investor confidence while addressing long-standing concerns about resource ownership and value distribution. In a sector often defined by tension between host countries and operators, it offers a more balanced approach. At the same time, Barrick’s operations have extended beyond mining into social and community investment. Programmes in education, healthcare and water infrastructure have been rolled out in mining regions, alongside initiatives like the ‘Future Forward Programme’, which aims to expand access to schooling. These efforts are designed to strengthen the company’s social licence to operate, an increasingly critical factor in modern mining.
The progress has not come without challenges as legacy issues, particularly around community relations at North Mara, continue to require careful management. Land use concerns, environmental questions and past grievances mean that maintaining trust with local communities remains an ongoing process rather than a completed task. Regulation is another evolving factor. Tanzania has introduced reforms that increase government participation and tighten compliance requirements. While these changes have improved oversight and governance, they also add layers of complexity for operators navigating the regulatory landscape. Operationally, the mines themselves are not simple. Deep underground mining at Bulyanhulu, combined with complex ore processing and cost pressures, requires continuous investment and technical expertise. Add to that the inherent volatility of global gold prices and it becomes clear that sustaining performance is as demanding as achieving it.
Barrick’s strategy in Tanzania is focused on longevity and expansion. Exploration is ongoing, targeting extensions of existing deposits and identifying new opportunities in underexplored areas. Infrastructure upgrades are improving efficiency and unlocking additional resources, while plans for a Special Economic Zone linked to mining operations point to a broader vision of industrial development. The wider impact on Tanzania’s economy is significant. Gold remains the country’s leading export and Barrick’s operations are among the largest contributors to export earnings, government revenue and foreign investment. Beyond direct financial contributions, the development of skills, local industries and infrastructure is helping to reshape the mining sector’s role in the national economy.
In the global context, Tanzania is firmly positioned as one of Africa’s leading gold producers, supported by strong geology, established infrastructure and growing investor interest. As demand for gold continues, driven by its role as a safe-haven asset in uncertain economic times, the country’s importance in the global market is likely to endure. Barrick’s journey in Tanzania ultimately reflects a broader shift in how mining is approached on the continent. It is no longer just about extracting resources but about building partnerships, sharing value and creating lasting economic impact. The transition from conflict to collaboration has not only revived the company’s operations but also set a precedent for how resource development can be managed more sustainably. As Tanzania’s gold sector continues to evolve, Barrick through Twiga remains at the centre of that story. Not simply as an operator but as a participant in shaping a more balanced and integrated model of mining, one where performance and partnership are expected to go hand in hand.
