Rwanda Opens 10 High-Potential Mineral Blocks to Attract New Wave of Global Investors

Rwanda has opened a new window for mining investment after releasing the second edition of its Mining Investment Pitchbook for 2025, a portfolio featuring ten exploration, mining and gemstone blocks now available to both local and international investors.

The announcement was made on December 3 at the Kigali Convention Centre during Rwanda Mining Week, an annual platform the government uses to attract strategic partners to its fast growing minerals sector.

The newly listed blocks include four ready for mining sites, four exploration zones and two gemstone rich areas. They cover a diverse range of minerals including tin, tantalum, niobium, lithium, beryllium, wolframite, gold and high value gemstones such as sapphires and tourmaline.

Rwanda Pushes for Smarter Investment and Stronger Partnerships

The Rwanda Mines, Petroleum and Gas Board (RMB) Chief Executive Officer Alice Uwase urged investors to express interest early, stressing that the country has strengthened its geological knowledge base to make investment decisions more predictable.

“Reliable exploration data is the foundation of any successful mining project. Without clear and verified data, investors hesitate even when the minerals are available,” she said, adding that financing for Rwandan companies and targeted incentives remain key to strengthening the sector.

Uwase emphasized that companies vying for concessions must demonstrate technical expertise and sufficient equipment, not merely financial backing, with joint ventures encouraged where necessary.

The 2025 edition of the Pitchbook features zones with verified historical work as well as new targets identified using updated geological research. According to RMB, licensing procedures have also been streamlined to enhance transparency and governance.

Applications for the ten blocks will remain open until March 3, 2026, with guided site visits planned for January so potential investors can carry out on the ground assessments.

During the first edition of the Pitchbook, RMB received 73 applications for 10 blocks, an indicator officials say of the sector’s increasing competitiveness.

Inside the 10 Blocks Now Open to Investors

1. Binyeri Block in Kamonyi District (70 ha)

Located in Rukoma Sector, the area hosts pegmatite fields known for cassiterite, coltan, lithium and beryllium. Previous surveys including work done in 2015 and 2018 confirmed strong mineral potential across the Bugoba zone and neighbouring regions.

2. Musenyi Block in Bugesera District (1,100 ha)

Close to the Bugesera granite, the block is rich in tin bearing pegmatites. Earlier studies recorded tin grades of up to 0.2 percent, and the site has a history of mining activity, making it a brownfield with reduced exploration risk.

3. Rubiha Block in Gatsibo District (450 ha)

Situated in Rugarama and Kiziguro sectors, this area falls within a tin rich corridor where cassiterite purity has been reported as high as 99 percent. Its mineralisation is linked to granitic intrusions that also host tantalum and niobium.

4. Minazi Block in Gakenke District (700 ha)

Covering Minazi, Coko and Rushashi sectors, this is one of the most diverse blocks. It shows potential for tin, coltan, gemstones, rare metal pegmatites and gold. Earlier stream sediment and rock chip sampling under PTA R2 identified tantalum grades of 100 to 200 ppm and approximately 12,000 tonnes of potential resources.

5. Shyorongi Block in Rulindo District (3,175 ha)

Mineralisation here is associated with leucogranite intrusions known to host niobium, tantalum, tin, tungsten and gold. Extensive sampling campaigns reveal similar tantalum grades to those found in Minazi.

6. Bihembe Block in Rwamagana District (3,175 ha)

Located in Nzige, Muyumbu, Nyakariro and Karenge sectors, the area is influenced by Bugesera and Kigali leucogranites. Stream sediment values indicate the presence of tin, lithium, niobium and tantalum.

7. Kabagari Kinihira Block in Ruhango District (1,500 ha)

This block contains cassiterite, coltan, lithium, beryllium and gemstones. PTA N2 and N3 studies show modest but consistent traces of key strategic minerals including niobium and beryllium.

8. Kivumu Nyamyumba Block in Rubavu District (875 ha)

Known for cassiterite, wolframite and beryl, the block is located in a zone with several pegmatite hosted mineral occurrences.

9. Bushekeri Rangiro Block in Nyamasheke District (1,400 ha)

One of the two gemstone only blocks, the area features sapphire, amethyst, smoky quartz, ruby and black spinel. Sapphires typically range from 2 mm to 8 mm, with rare specimens reaching up to 15 mm.

10. Kanama Block in Rubavu District (1,575 ha)

Situated within the Gishwati Complex, this gemstone block hosts tourmaline, beryl, almandine and sapphire. Large dolerite boulders found in rivers can be processed for additional mineral recovery.

Government Calls for More Value Addition

RDB’s Chief Investment Officer Michelle Umurungi encouraged investors to go beyond extraction and focus on refining minerals locally.

“Rwanda is building pathways for processing key minerals such as tantalum, tungsten and gold. Our goal is to create a business environment where investors can access modern geological data and add value within the country,” she noted.

RMB’s Chief Geo Hazard Officer Barbara Akaliza highlighted that applicants must also present clear development plans, stating, “We expect investors to outline strategies for the first, third and fifth years of the project.”

Growing Interest in Rwanda’s Minerals Sector

As global demand for critical minerals rises driven by electric vehicles, renewable technologies and advanced electronics, Rwanda aims to position itself as a competitive and transparent destination for exploration and mining investment.

With enhanced geological mapping, stronger governance systems and diversified resource potential across the ten newly opened blocks, officials say the country is ready to welcome experienced miners seeking long term partnerships.
