Bihar Looks to Convert Rs 21,000-Crore Mineral Finds into Working Mines

For twenty-five years after the 2000 bifurcation that carved out Jharkhand, Bihar carried the tag of a state left with the floods while its neighbour took the fortune. Stripped of almost its entire mineral base overnight, it settled into a largely agrarian economy. That narrative is now being tested.

Geological investigations carried out between 2021 and 2024 across Rohtas, Jamui and Gaya have identified mineral reserves valued at more than Rs 21,000 crore. State officials estimate that bringing these deposits into production could push annual mining revenue past Rs 5,000 crore, well above Bihar's current record collection of Rs 3,592 crore, which comes almost wholly from minor minerals such as sand and stone quarrying.

A senior official in the mining department said the value and commercial potential of the finds had been assessed, adding that the state was now at a stage that could yield commercial success from 2026-27.

What has been found

In Rohtas, glauconite deposits spread across the Pipradih-Bhurwa and Chutia-Nauhatta blocks are estimated at about 130.11 million tonnes, valued at Rs 14,048 crore. Glauconite is a source of potassium for potash fertilisers, a commodity India imports almost entirely. The district also holds high-grade limestone in the Bhora-Kathra block, with 33 to 39.68 million tonnes valued at Rs 1,761.42 crore, used in Portland cement and quicklime. Amjhor accounts for nearly 95% of the country's known pyrite deposits, a mineral used to make sulfuric acid and in industrial chemical processing.

Magnetite, an iron ore, has been identified in the Majos and Bhanta blocks. Majos, at the G2 stage of exploration, holds 48.40 million tonnes valued between Rs 3,817.60 crore and Rs 6,000 crore, while Bhanta, at G3, has 6.49 million tonnes worth Rs 511.91 crore. Both feed steelmaking and other metallurgical industries.

In the Sono area of Jamui, gold-bearing ore of 222.88 million tonnes contains roughly 37.6 tonnes of gold metal. Classified as a remaining resource rather than a reserve, it accounts for about 43% of India's primary gold ore resources. Preliminary exploration has begun, with trial production targeted for 2027-28.

In Gaya and Jehanabad, the Patalganga and Sapneri areas have thrown up vanadium-bearing magnetite, ilmenite and rare earth elements, along with lithium-bearing pegmatites. Vanadium goes into high-strength steel and energy storage, ilmenite yields titanium dioxide, and lithium and rare earths are used in EV batteries, wind turbines and defence technology.

The road to extraction

Officials say the Rs 21,000-crore figure rests on geological assessments that factor in extraction costs, beneficiation and logistics. Exploration by the Geological Survey of India moves through four stages, from G4 reconnaissance to G1 detailed exploration. To move from early survey findings to extraction between 2026 and 2031, Bihar has aligned its legal and administrative framework with mineral-rich states such as Odisha and Jharkhand under the amended Mines and Minerals (Development and Regulation) Act.

To reduce risk for bidders during early exploration, the Ministry of Mines has introduced reimbursable private agency models through the National Mineral Exploration Trust. A roadmap sets six months for submitting mining plans, 18 months for environmental clearances and 12 months for lease execution. The phase-wise plan includes the launch of the eighth tranche of critical mineral auctions in Patna in August 2026, advanced G2 and G1 drilling under composite licences in 2026-27, trial production at the Sono gold site in 2027-28, and full commercial extraction in the 2026-2031 window.

Bihar Geology and Mines Minister Pramod Kumar recently announced a 1,000-strong specialised Mines Police Force, structured on the lines of the state's excise police, to check illegal mining and protect the deposits.

Hurdles ahead

Structural delays persist. National mining rules require at least three technically qualified bidders for each block, and early auction tranches for Bihar's glauconite and nickel blocks had to be annulled after low turnout, with private miners reluctant to bid high on preliminary exploration data.

Infrastructure and technology add to the difficulty. Extracting agricultural-grade potash from hard-rock glauconite and refining vanadium from magnetite call for capital-intensive technologies that are still being developed domestically. Although many blocks sit on non-forest land, surface rights in agrarian Bihar are fragmented among thousands of private landowners, creating friction over land acquisition alongside mandatory statutory approvals such as environment and forest clearances and pollution control board consents.

KPS Keshri, former president of the Bihar Industry Association, said it remains to be seen how the mines are converted into revenue. He noted that while the state had found and explored vast reserves after bifurcation, it was up to the government to determine the scale at which they could be turned into income and how an industry could be built around the discoveries.
