Critical Minerals in Tanzania: Why the World Needs What Tanzania Has

What if the minerals powering tomorrow's electric vehicles and wind turbines are sitting right beneath our feet and most of the world hasn't even noticed?

That is not a rhetorical question. It is the reality of Tanzania's critical minerals sector. For years, the world has looked to Tanzania for gold and rightly so, as Africa's fourth-largest producer. But beneath that gold narrative lies a much bigger story. One that involves graphite, nickel, cobalt, copper, rare earth elements, and the global energy transition.

The world is racing to decarbonise. Electric vehicles, battery storage, wind turbines, and renewable energy infrastructure all depend on a suite of minerals that most people have never heard of. And Tanzania has them. In significant quantities. The question is no longer whether the world needs what Tanzania has. It is whether global investors and manufacturers will recognise the opportunity before it is too late.

Let us explore why Tanzania's critical minerals matter and why now is the time to pay attention.

So, What Exactly Does Tanzania Have?

For decades, Tanzania's mining story was primarily a gold story. That makes sense: gold exports earned the country US$4.7 billion in the year ending November 2025. That is a lot of gold.

But the more compelling narrative today is the one happening beneath that gold-focused history. Tanzania has officially identified 25 critical and 18 strategic minerals. These include:

• Graphite - Tanzania holds approximately 6% of the world's graphite reserves, with some estimates placing total resources at nearly 323.8 million tonnes.

• Nickel - The Kabanga Nickel Project is believed to be one of the world's largest and highest-grade development-ready nickel sulphide deposits.

• Copper and Cobalt - found alongside nickel in Kabanga and elsewhere.

• Rare earth elements - including Neodymium and Praseodymium, critical for electric vehicles, wind turbines, smartphones, and defence systems.

• Other strategic minerals - including lithium, titanium, niobium, helium, and more.

This is not a speculative inventory. It is a documented, government-verified resource base that is now attracting serious global attention.

Take graphite, for example. The Mahenge graphite mine, operated in partnership with Australia's Black Rock Mining and South Korea's POSCO International, contains approximately 6 million tonnes of natural graphite reserves. It is expected to supply 60,000 tonnes annually for about 25 years. The Lindi Jumbo Project boasts some of the world's highest-grade deposits with 17.9% Total Graphitic Carbon reserves. That is not a niche project - that is a world-class resource.

Then there is the Ngualla Rare Earth Project in the Songwe Region, considered one of the world's largest undeveloped rare earth deposits. And the Kabanga Nickel Project, which also contains substantial copper and cobalt resources, is advancing toward a Final Investment Decision in 2026.

So yes, Tanzania has what the world needs.

Why Does the World Need These Minerals So Badly?

The global context explains why all of this matters. According to the International Energy Agency's Global Critical Minerals Outlook 2025, demand for lithium is set to grow fivefold by 2040. Cobalt demand will double. Copper demand will rise by 30%. Graphite and nickel demand will also double.

This is not abstract economics. This is the physics of the energy transition.

Electric vehicle batteries require lithium, cobalt, nickel, and graphite. Wind turbines and solar installations require copper, rare earth elements, and aluminium. Energy storage systems depend on the same suite of minerals.

The sheer scale of future requirements is staggering. It is estimated that by 2050, some 3 billion tonnes of minerals and metals could be needed for wind, solar, and geothermal energy alone. That is not a typo — billion, with a B.

Three major trends are reshaping the global minerals landscape:

1. Security of supply - countries are scrambling to secure access to critical minerals.

2. Clean energy cost parity - renewable energy is becoming cheaper, but only if the minerals are available.

3. Equitable resource partnerships - resource-rich countries are demanding more value from their resources.

Tanzania's membership in the Minerals Security Partnership - a global framework aimed at securing supply chains for critical minerals - reflects just how strategically important its resource base has become. The competition for critical raw materials is intensifying, and Tanzania is right at the centre of it.

What Is Tanzania Doing About It?

The Tanzanian government is not sitting back and letting this opportunity pass by. The centrepiece of the reform agenda is the National Strategy for Critical Minerals, which the government is finalising for 2030. The strategy will identify the types, quantities, and geographical locations of minerals essential to global industries.

But here is where it gets really interesting. The strategy is not just about extraction. It is focused on building capacity across the entire value chain from exploration and mining to processing, manufacturing, and recycling. That is a fundamental shift from a mining economy centred on extraction to one focused on beneficiation, processing, and industrial value addition.

President Samia Suluhu Hassan has also directed the Ministry of Minerals to expand the country's exploration coverage to 50% by 2030. That is a serious commitment to expanding the resource base.The results of this strategic approach are already visible. The mining sector now contributes approximately 10% to 12.7% of Tanzania's GDP up from just 4% in 2007. The sector achieved the Vision 2025 target of 10% GDP contribution a year early, in 2024. In 2025, minerals contributed 52.57% of Tanzania's traditional and non‑traditional exports, up from 45.17% in 2024.

The government has also identified 14 high‑value opportunities across 11 strategic and critical minerals that could generate at least US$7.2 billion annually. That is a roadmap for investment.

What Does This Mean for You?

If you are reading this, chances are you are an investor, equipment supplier, off‑taker, or service provider looking at Tanzania's mining sector. And you are probably wondering: what does all of this mean for me?

Here is the honest answer: the opportunity is massive, but the complexity is real. Navigating licensing, local content rules, value‑addition mandates, and community relations is not straightforward. It requires local presence, regulatory fluency, and operational capability.

The firms that win in Tanzania's critical minerals sector will not be those with the boldest predictions. They will be those with the deepest relationships, the clearest understanding of the regulatory landscape, and the commitment to move from exploration to production — and from production to value addition.

That is where Simba Ustawi comes in.

We hold active gold processing and copper mining licenses in Tanzania. We operate on the ground. We have proven partnerships with Tembo and Amani. We understand the regulatory environment, the infrastructure challenges, and the opportunities.

Whether you are an equipment supplier looking for a local partner, an off‑taker seeking high‑quality copper and gold, or a co‑investor ready to deploy capital, we are the partner who can make it happen.

Conclusion

Tanzania's critical minerals story is not a forecast it is already being written. The graphite mines are operating. The nickel project is advancing. The rare earth discoveries are being evaluated. 

The policy framework is in place. The global demand is rising.

The world needs what Tanzania has: substantial, diverse, and strategically significant mineral resources that are essential to the energy transition. Tanzania, in turn, needs partners who understand that success in this sector requires more than capital - it requires local presence, regulatory fluency, and operational capability.

That is exactly what Simba Ustawi offers.
