Why Technology Metals

Technology Metals for a Modern World

The global shift toward clean energy, electric mobility, and advanced technology is driving unprecedented demand for critical and technology metals.

Rare Mining East Africa Limited is strategically positioned to supply metals essential for the modern world, including tin, nickel, copper, cobalt, and gold.

Technology metals are fundamental to:
• Electric vehicle batteries and charging infrastructure
• Renewable energy systems
• Electronics and advanced computing
• Robotics and industrial automation

Tin is indispensable for electronics soldering, accounting for nearly half of global usage. Nickel and cobalt are critical components in high-performance EV batteries and superalloys. Copper underpins electrification and energy transmission worldwide.

While demand continues to accelerate, global supply is constrained by aging mines and a shortage of new discoveries. This growing supply gap presents a compelling opportunity for well-positioned exploration companies.

Rare Mining East Africa Limited is actively seeking partners to help unlock the next generation of critical metal resources.

Why Tanzania

One of Africa’s Most Attractive Mining Jurisdictions

Tanzania is one of Africa’s most attractive and stable mining jurisdictions, offering a strong foundation for long-term exploration and development.

Key advantages include:
• A stable political environment
• A modern and transparent Mining Act (2010)
• Competitive fiscal and tax regimes
• Established mining governance and regulatory frameworks

The country benefits from world-class infrastructure, including:
• Major road and rail networks
• International ports and airports
• Reliable telecommunications
• Access to regional power grids

Tanzania hosts several globally significant mines, such as Geita, Bulyanhulu, and North Mara, and is endowed with a wide range of commodities including gold, base metals, rare earths, and gemstones.

With a country risk profile comparable to South Africa, Tanzania provides an excellent platform for responsible and scalable mineral development.
