The Mining Act (Cap. 123 RE 2019) governs Tanzania's extractive sector — licence types, royalty regime, beneficiation mandates, and the Mining Commission's enforcement role — and was last comprehensively restructured in the 2017–2018 reform wave that introduced the Permanent Sovereignty Act and the original local-content regulations. The Written Laws (Miscellaneous Amendments) (No. 4) Act, 2024 (Bill No. 15 of 2024, gazetted 5 November 2024 in Special Gazette No. 34 Vol. 105) is the first parliamentary instrument since the 2017 wave to materially expand the classification authority and entry-threshold layers of the Mining Act.
The mining-related amendments operate on five axes:
1. Critical and strategic mineral classification authority (new). The Minister for Minerals is empowered, on recommendation from the Geological Survey of Tanzania (GST), to declare a mineral as either: - Critical — essential to national economic, geopolitical consideration, technology, or industrial use, with supply limited or threatened. - Strategic — a mineral resource with diplomatic or defence importance. This is the first Tanzanian statutory mechanism for such classification. Once declared, the Mining Act and downstream regulations can attach differential treatment (export licensing, stockpiling, royalty, beneficiation, sovereign-equity participation) to the classified mineral category. The classification list itself is delegated to GST recommendation + ministerial declaration. 2. USD 5,000,000 minimum capital floor for Mining Licences (50× hike). The minimum capital investment threshold for a Mining Licence rises from USD 100,000 to USD 5,000,000. The Mining Licence (ML) is the mid-tier title between the Primary Mining Licence (PML, Tanzanian- nationals-only artisanal layer) and the Special Mining Licence (SML, large-scale projects). The 50× capital floor effectively prices out junior explorers and small-cap foreign developers from the ML tier, concentrating mid-scale operations toward better- capitalised players or driving them up to SML negotiation. 3. Gemstone-export carve-out via organised auctions / gem fairs. The general restriction on raw-mineral and concentrate export (introduced by the 2017 Mining (Mineral Beneficiation) Regulations regime requiring in-country beneficiation) is retained, but gemstones disposed of through government-organised mineral auctions or international gem fairs receive a statutory carve-out for export. This formalises the existing TANZANITEONE / Mererani gemstone- marketplace channel. 4. GST sample-data verification. Mineral right holders exporting samples must have the underlying mineral data verified by GST. This converts what was an administrative inspection function into a statutory pre-clearance, providing a chokepoint for unauthorised sample export and giving GST a legal basis to enforce sampling-fee collection. 5. Penalties for false mineral data + 28-day application-fee deadline. Mineral right holders submitting inaccurate or false mineral data face penalties under the Act. Failure to pay application fees for grant of mineral rights within 28 days of notification deems the application withdrawn — speeding up rights-allocation processing.
The Bill was introduced as the Written Laws (Miscellaneous Amendments) (No. 4) Bill, 2024 (Bill No. 15 of 2024 in the parliamentary order), amending eight Acts: the Advocates Act (Cap. 341), Basic Rights and Duties Enforcement Act (Cap. 3), Community Service Act (Cap. 291), Immigration Act (Cap. 54), Kariakoo Market Corporation Act (Cap. 132), Land Act (Cap. 113), Mining Act (Cap. 123), and Public Service Act (Cap. 298). The Mining Act amendments are the substantive industrial- policy content; the other amendments are administrative.
export-control regime.* The Act doesn't itself impose export controls — it creates the classification authority* on which subsequent ministerial export-licensing or beneficiation orders can be predicated. This mirrors the architecture of Indonesia's hilirisasi (where Permendag and Permen ESDM orders rely on the Minerba Law's classification authority) and China's MOFCOM rare-earth export controls (predicated on the Foreign Trade Law's dual-use catalogue authority). Watch for follow-on Mining Commission gazette notices declaring specific Tanzanian minerals (graphite, niobium, REE, nickel, helium) as critical or strategic.
Where Tanzania's GN 563/2025 captures the services-and-supplier margin of the extractive base, this Act establishes the classification authority needed to capture downstream processing and export margin on a mineral-by-mineral basis. The two instruments (GN 563/2025 + this Act) together build the supplier- layer + classification-authority stack on top of the 2017 Permanent Sovereignty + 16% free-carried-interest baseline.
Mining Licence tier effectively excludes most ASX-listed and AIM-listed junior explorers from the mid-tier title. Existing ML-holders may face renewal-stage scrutiny; new entrants must either capitalise above USD 5m or negotiate at the SML scale. This concentrates Tanzanian mid-scale mining toward better- capitalised mining majors and Chinese state-linked developers.
globally significant deposits across the modern critical-minerals basket: Nachu graphite (EcoGraf, Magnis), Lindi graphite, Kabanga nickel-cobalt (BHP/Lifezone JV — world's largest undeveloped sulphide), Ngualla NdPr REE (Peak Rare Earths — among the world's top-5 NdPr-rich deposits), Panda Hill niobium, Rukwa helium (Helium One). The classification authority gives the Tanzanian state a structured mechanism for differential treatment of these deposits — favourable to FID-ready major projects, restrictive to raw-export models.
register.** The existing TZ entry (GN 563/2025 local-content amendment) covers procurement-layer regulation under the Mining Commission's section 112 delegated authority. This Act is a parliamentary statute amending the Mining Act itself — distinct legal instrument, distinct authority, distinct downstream policy surface. Future TZ filings (mineral-classification gazette notices, Mining Act royalty changes, beneficiation orders) will reference this Act as the enabling statute.
declaration list of critical / strategic minerals has not yet been gazetted (as of May 2026). Watch Mining Commission and Ministry of Minerals notices. The plausible first declarations: graphite, niobium, NdPr REE, nickel-cobalt (Kabanga), helium.
authorises classification but does not itself prescribe what policies follow. Open: will critical-mineral status trigger beneficiation-in-Tanzania mandates, export-licensing controls, state participation requirements, royalty differentials, or stockpiling obligations? Each is a downstream policy choice.
Act 2024 gold-reservation rule.** The 2017 Permanent Sovereignty Act gave the state 16% free-carried interest and "unconscionable contract" renegotiation rights; the Finance Act 2024 introduced gold-reservation for local refining. Critical-mineral classification could layer additional sovereign-equity or reservation mandates onto specific minerals. Cumulative IRR effect on foreign investors is the open analyst question.
threshold.** Whether existing ML holders below the new capital floor are grandfathered, required to recapitalise, or downgraded to PML status at renewal is a Mining Commission discretion that will set the practical tightness of the regime.
bilateral investment treaties with the UK, Germany, the Netherlands, Canada, China, India, and others. Differential treatment of foreign mining-licence holders predicated on critical-mineral classification could face investor-state challenge. The WTO Appellate Body's non-functionality (cf. EU DS592 on Indonesia nickel) limits multilateral enforcement.
