Australia listed gold producer Perseus Mining says it has invested more than TZS 457.7 billion, equivalent to approximately US$174.6 million, into Tanzania’s economy as construction progresses at the Nyanzaga Gold Project, one of East Africa’s most significant emerging gold developments.
According to the company, the investment was made through its Tanzanian subsidiary, Sotta Mining Corporation, between July 2024 and March 2026. The expenditure forms part of the project’s development phase ahead of planned commercial production during the first quarter of 2027.
Company figures indicate that TZS 371.6 billion was directed towards locally procured goods and services, while TZS 60.7 billion was paid in taxes and statutory obligations. A further TZS 25.1 billion was allocated to employee salaries and benefits, reflecting the project’s growing contribution to economic activity within Tanzania.
The Nyanzaga Gold Project, located in Tanzania’s Mwanza Region, is currently estimated to be approximately 50 per cent complete. Construction activities have supported employment for more than 3,600 people, including 281 direct employees, with the company stating that a significant proportion of the workforce has been recruited from surrounding communities.
Perseus Mining holds an 80 per cent interest in the project, while the Government of Tanzania retains a 20 per cent free carried interest through Sotta Mining Corporation, reflecting the country’s mining framework that seeks to increase national participation in strategic mineral assets.
The company has stated that the mine is expected to operate for at least 16 years once production begins. According to published mineral resource estimates, Nyanzaga contains approximately four million ounces of gold resources, positioning it among Tanzania’s most substantial undeveloped gold assets.
Speaking on behalf of Sotta Mining Corporation, Country Manager Isaac Lupokela said the company remained committed to creating long term value for both local communities and the Tanzanian economy through responsible mining practices.
Beyond construction activities, the company reported that it had delivered more than 200 training opportunities over the past year while establishing a Community Employment Committee intended to strengthen transparency in recruitment and improve opportunities for local residents to participate in the project’s workforce.
Perseus Mining also highlighted investments in community infrastructure and social development. These include improvements to local water supply systems, health and safety awareness initiatives, the construction and replacement of primary school facilities, development of a community dispensary and the construction of the Ngoma Bypass Road, which is intended to improve road safety and connectivity within the surrounding area.
The Nyanzaga development comes as Tanzania continues to consolidate its position as one of Africa’s leading gold producing nations. According to the Bank of Tanzania, the country’s official gold reserves have expanded significantly in recent years as authorities seek to strengthen macroeconomic resilience and increase the strategic role of domestically produced gold.
Mining remains one of Tanzania’s principal sources of export earnings and foreign direct investment. The sector has attracted sustained capital investment as successive policy reforms have sought to balance investor confidence with greater national participation and value creation within the country’s mineral economy.
Across the continent, gold continues to play an important role in economic development, public revenue generation and industrial investment. While Ghana has emerged as Africa’s largest gold producer in recent years, significant production also comes from South Africa, Mali, Burkina Faso, the Democratic Republic of Congo and Guinea. New mine developments and expansions across several African jurisdictions illustrate a broader continental trend towards increasing production while seeking to maximise local economic benefits through procurement, employment and infrastructure development.
For many African governments, the emphasis is increasingly shifting beyond mineral extraction alone towards ensuring that natural resource development contributes to industrialisation, skills development and community wellbeing. Projects such as Nyanzaga are therefore being assessed not only on projected production volumes but also on their wider economic footprint, including local procurement, workforce participation, fiscal contributions and long term investment in host communities.
As construction advances towards first gold production in early 2027, the Nyanzaga Gold Project represents another milestone in Tanzania’s evolving mining industry and reflects the broader transformation taking place across Africa’s resource sector, where governments, investors and communities are increasingly focused on achieving more inclusive and sustainable outcomes from the continent’s mineral wealth.
