Critical mineral block auctions: Centre roadshow in Patna for 8th tranche, 20 blocks on offer
Synopsis
The Centre is pitching 20 mineral blocks — spanning rare earths, vanadium, gallium, and graphite — to investors at a Patna roadshow on 18 August, the 8th such tranche in India's accelerating critical minerals auction programme. With clean energy and semiconductor supply chains under global pressure, how fast India can unlock these blocks matters well beyond the mining sector.
Key Takeaways
The Union Ministry of Mines is organising a roadshow in Patna on 18 August 2025 for the 8th tranche of critical and strategic mineral block auctions.
The tranche includes 20 blocks — 3 mining leases and 17 composite licence blocks — covering minerals such as graphite, REE, vanadium, gallium, titanium, tungsten , and others.
The event will be chaired by Minister of State Satish Chandra Dubey , with Bihar CM Samrat Choudhary and state Mines Minister Pramod Kumar attending.
Presentations will be made by MECL , SBICAPS , and MSTC on block details, the auction process, and e-auction mechanics.
The NMEDT Scheme offers partial reimbursement of exploration expenses for composite licence holders to incentivise private participation.
A technical workshop on 'Mineral Exploration: Planning, Execution and Reporting' by senior GSI officers will run in the second half of the programme.
The Union Ministry of Mines is set to hold a roadshow in Patna on Monday, 18 August 2025, to promote the 8th Tranche of Auction of Critical and Strategic Mineral Blocks, alongside a workshop on the National Mineral Exploration and Development Trust (NMEDT). The event, announced via an official statement on Sunday, marks another step in the Centre's push to accelerate domestic critical mineral development and attract private investment.
What the 8th Tranche Covers
The 8th tranche comprises 20 mineral blocks — including 3 mining leases and 17 composite licence blocks. The blocks cover a wide range of critical and strategic minerals: graphite, rare earth elements (REE), rare metals, vanadium, gallium, titanium, molybdenum, tungsten, potash, phosphorite, and glauconite. These minerals are essential inputs for clean energy technologies, semiconductors, and defence applications — sectors where India has historically depended on imports.
Key Officials and Stakeholders Present
The programme will be chaired by Union Minister of State for Coal and Mines Satish Chandra Dubey. Bihar Chief Minister Samrat Choudhary, state Mines Minister Pramod Kumar, and senior officials from the state government, the Geological Survey of India (GSI), and Mineral Exploration and Consultancy Limited (MECL) will also attend. Industry representatives and prospective investors are expected to participate.
What the Roadshow Will Feature
Detailed presentations will be made by MECL on the mineral blocks on offer, SBICAPS on the auction process and tender documentation, and MSTC on the e-auction mechanism. A dedicated session will cover the NMEDT Scheme, which provides partial reimbursement of exploration expenses for composite licence holders — a financial incentive designed to lower the risk threshold for private explorers. An open-house discussion will follow to address investor queries.
Workshop on Mineral Exploration
The second half of the programme features a technical workshop titled 'Mineral Exploration: Planning, Execution and Reporting'. Sessions by senior GSI officers will cover India's broader mineral exploration potential, the National Geoscience Data Repository (NGDR), preparation of exploration blocks using NGDR data, and standards for mineral exploration reporting. This component targets both new entrants and established players seeking to navigate India's evolving exploration regulatory framework.
Broader Policy Context
The initiative is part of the Centre's sustained effort to reduce import dependence on critical minerals — a vulnerability that has gained strategic urgency as global supply chains for clean energy and advanced manufacturing tighten. India has been ramping up auction tranches since amending the Mines and Minerals (Development and Regulation) Act to allow composite licences, which combine exploration and mining rights. The roadshow also aligns with the Atmanirbhar Bharat framework, with officials stating that greater domestic exploration is essential for sectors ranging from electric vehicles to renewable energy. With Bihar hosting the event, the exercise additionally signals the Centre's intent to draw eastern India's geological endowment into the national minerals pipeline.
Point of View
The pace of India's critical mineral auctions is accelerating — but the harder question is whether investor uptake is keeping pace with block supply. Composite licences were meant to de-risk exploration for private players, and the NMEDT reimbursement scheme adds another layer of incentive, yet the sector still lacks the deep geological data and tenure security that global mining majors demand. Hosting the roadshow in Patna is politically smart — Bihar has untapped mineral potential and the optics of federal-state coordination are useful — but eastern India's infrastructure gaps remain a structural deterrent. The real test of this programme is not how many blocks are auctioned, but how many reach production within a credible timeframe.

Frequently Asked Questions
What is the 8th tranche of critical mineral block auctions?
It is the latest round of government-led auctions of critical and strategic mineral blocks, comprising 20 blocks including 3 mining leases and 17 composite licence blocks. The blocks cover minerals such as graphite, rare earth elements, vanadium, gallium, titanium, molybdenum, tungsten, potash, phosphorite, and glauconite.
Where and when is the roadshow being held?
The roadshow is being held in Patna, Bihar, on Monday, 18 August 2025. It is organised by the Union Ministry of Mines and will be chaired by Minister of State for Coal and Mines Satish Chandra Dubey.
What is the NMEDT Scheme and why does it matter?
The National Mineral Exploration and Development Trust (NMEDT) Scheme provides partial reimbursement of exploration expenses to composite licence holders. It is designed to lower the financial risk for private investors entering early-stage mineral exploration, encouraging greater private-sector participation in India's critical minerals sector.
Why are these minerals considered critical or strategic?
Minerals such as rare earth elements, vanadium, gallium, and graphite are essential inputs for electric vehicles, renewable energy systems, semiconductors, and defence technologies. India currently depends significantly on imports for many of these, making domestic development a priority for supply chain security.
Who can participate in the auction process?
Industry representatives and prospective investors are invited to participate. The roadshow will walk attendees through the auction framework, bidding process, and investment opportunities, with detailed presentations by MECL, SBICAPS, and MSTC to guide potential bidders.
