Zanzibar Mineral Exploration Gains Momentum After Discovery of Heavy Mineral Sands

Speaking at the launch of the seventh Tanzania Mining and Investment Conference 2026 in Dar es Salaam, Ali Hassan Mrisho, Head of the Mineral Division within Zanzibar’s Ministry of Water, Energy and Minerals, said initial geological investigations had identified promising occurrences of heavy mineral sands, including ilmenite and zircon.

These minerals are important components of global industrial supply chains. Ilmenite is one of the world’s principal sources of titanium, which is widely used in aerospace engineering, construction materials, pigments and advanced manufacturing. Zircon is similarly valued for applications in ceramics, foundry casting, refractory materials and an expanding range of high-technology industries.

From geological indications to commercial assessment

According to Mrisho, the Zanzibar Government is working with the Geological Survey of Tanzania to undertake more detailed assessments aimed at determining the scale, quality and commercial viability of the identified resources before any significant extraction activities begin.

The distinction is important. Early geological indications do not confirm commercially recoverable deposits. They do, however, identify areas where exploration can now proceed in a more targeted and informed manner.

For investors, Zanzibar’s entry into structured mineral exploration broadens Tanzania’s mining narrative. Mainland Tanzania has established itself as one of Africa’s significant mining jurisdictions through the production of gold, diamonds, tanzanite, graphite, nickel and other strategic minerals. Zanzibar, by contrast, has historically maintained only a limited mining profile.

The current programme therefore represents an important first step in determining whether the islands possess mineral deposits capable of supporting future investment and commercial development.

Sustainability and long-term development in focus

Mrisho said the next phase of exploration will be conducted in accordance with sustainable development principles, with environmental stewardship and community participation at the centre of the programme.

Authorities aim to ensure that any future mineral development delivers broad-based economic benefits while protecting local livelihoods and natural ecosystems.

The initiative reflects a wider trend across Africa, where governments are placing greater emphasis on geological mapping and responsible resource development as part of broader economic transformation strategies. Many countries are investing in geological knowledge to strengthen resource governance, improve domestic value addition and attract long-term investment into their mining industries.

The timing is also notable. Rising global demand for minerals used in advanced manufacturing and energy-transition technologies has increased investor interest in previously underexplored regions across the continent.

Officials stressed that comprehensive scientific studies remain essential before decisions on commercial mining can be made. Further exploration will seek to establish the extent of the deposits while evaluating environmental considerations, technical feasibility and potential economic returns.

The announcement comes ahead of the Tanzania Mining and Investment Conference 2026, which brings together policymakers, geological experts, mining companies and investors to discuss opportunities within Tanzania’s evolving mineral sector. The event also serves as a platform for examining regulatory developments and investment prospects while exploring how mineral resources can support inclusive and sustainable economic growth.

For investors, the key takeaway is that Zanzibar mineral exploration remains at an early stage, but the direction is increasingly clear. The archipelago is moving methodically from preliminary geological indications towards evidence-based assessment and potential resource development.

The next signals to watch will be the results of detailed geological surveys and whether they identify deposits with sufficient scale and quality to justify commercial exploration and investment.
