In one of its clearest signals yet, the government of Tanzania has made it plain that holding mineral assets without development will no longer be tolerated by revoking 40 exploration licences in a sweeping enforcement action and placing a further 43 operators on notice to comply or face the same fate.
Minister of Minerals Anthony Mavunde ordered the Mining Commission to cancel the licences following repeated non-compliance, despite prior warnings and grace periods extended to operators. A ministry assessment found widespread breaches including the hoarding of exploration blocks without development activity, failure to pay statutory fees, non-compliance with local content rules and inadequate corporate social responsibility commitments.
“The government will not tolerate negligence that hinders the development of the mining sector and the broader economy. We have identified serious violations that undermine the sector’s potential. This enforcement action is a restoration of discipline and transparency in the country’s licensing framework,” said Mavunde at a briefing in Dodoma.
In addition, the revoked licences will be returned to the state and reallocated under Tanzania’s ‘Mining for a Brighter Tomorrow’ programme, which targets small-scale miners, capable investors and designated community groups to broaden inclusive participation in the sector. The 43 licence holders issued with compliance notices have 30 days to address outstanding violations or face similar cancellations, with officials indicating that reassignment to development-ready investors will follow swiftly where non-compliance persists.
This action places Tanzania within a continental pattern of tightening regulatory oversight. Across Africa, governments are increasingly moving from passive licence issuance to active enforcement by scrutinising whether mining rights are translating into production, employment and revenue rather than speculative asset holding. For Tanzania, the stakes are particularly high as it is the world’s sole source of tanzanite, a strategically significant gemstone concentrated near Mount Kilimanjaro.
The country is positioning itself as a critical minerals hub across graphite, nickel, lithium and gold as global energy transition demand accelerates. The message from Dodoma is unambiguous, in Tanzania’s mining sector, a licence is a commitment to develop not a speculative option to hold.
