Critical and Strategic Mineral Blocks auctions

GS3 Economy / MiningPrelims and Mains

Why in news
On 23 June 2026 the Ministry of Mines said 10 more critical mineral blocks were auctioned in the Seventh Tranche, taking the total to 56. It also reported the Second Tranche of Exploration Licence auctions, bringing those blocks to 11.
What it is
The Critical and Strategic Mineral Blocks auctions are tranche-wise e-auctions of mineral blocks run by the Ministry of Mines with State governments. They aim to build domestic supply of minerals needed for clean energy, electronics and defence, and to cut import dependence. Blocks are offered as Composite Licences (exploration plus mining) or Mining Leases.
Tranche size
The 8th Tranche has 20 mineral blocks: 17 Composite Licence blocks and 3 Mining Lease blocks, across nine States.
Auction record so far
88 critical and strategic mineral blocks have been offered, and 56 have been successfully auctioned.
Minerals on offer
Blocks include graphite, rare earth elements, vanadium, gallium, titanium, molybdenum, tungsten, potash, phosphorite and glauconite.
Exploration support
The NMEDT scheme partially reimburses exploration expenses of Composite Licence holders.
Unified Mining Portal
The portal is meant to ease doing business and coordinate Centre and States for faster approvals and operationalisation.
Legal basis
Auctions of mineral blocks are conducted under the Mines and Minerals (Development and Regulation) Act, 1957, as amended in 2015 and 2023.
Size of the eighth tranche
20 blocks are on offer: 13 newly identified and 7 under the Second Attempt.
Cumulative progress
Across all tranches, 88 critical mineral blocks have been offered and 56 auctioned so far, as stated by the Ministry's Secretary.
Auction method
Online two-stage ascending forward auction. The preferred bidder is the one quoting the highest percentage of the value of mineral dispatched.
Total auctioned
56 critical and strategic mineral blocks have been auctioned out of 88 unique blocks taken up by the Centre, a success rate of over 63%.
Seventh Tranche
The NIT was issued on 23 March 2026 offering 19 blocks. Ten were auctioned, with first-time blocks in Gujarat, Uttarakhand and Telangana.
Exploration Licence
The second EL tranche extended the framework to Arunachal Pradesh, Uttar Pradesh and Odisha for the first time. Cumulative EL blocks auctioned by the Centre are 11.
Minerals in tranche
The Seventh Tranche included graphite, rare earth elements, vanadium, titanium, glauconite and rock phosphate.
Who gets the revenue
Auction revenue goes to the State Governments where the blocks lie, even though the Centre conducts the auction.
Insurance Surety Bond
The Mineral (Auction) Amendment Rules, 2026 allow an Insurance Surety Bond as an alternative to bank guarantees.
Post-auction timelines
The Mineral (Auction) Second Amendment Rules, 2025 streamlined the timelines for performance security, upfront payment and Letter of Intent.

Don’t confuse with Composite Licence vs Mining Lease: A Composite Licence covers both exploration (prospecting) and mining; a Mining Lease is for mining in an already explored block.

Don’t confuse with NMET vs NMEDT: The National Mineral Exploration Trust (NMET) funds exploration; the release names the NMEDT scheme for partial reimbursement of exploration costs for Composite Licence holders. Check the exact name when it is asked.

Don’t confuse with Exploration Licence vs Composite Licence: An Exploration Licence is for exploration of critical and deep-seated minerals. A Composite Licence covers both exploration and mining in one grant.

Don’t confuse with Mining Lease vs Composite Licence: A Mining Lease allows mining of a block that is already explored. A Composite Licence covers exploration first and then mining in one grant.

Don’t confuse with Forward vs reverse auction: In a forward auction, bidders compete upward, as here on the percentage of value of mineral dispatched. In a reverse auction, bidders compete downward on price.

Economy terms and data: 42 Prelims questions since 2013, rising in recent years; they test what a term or instrument means. In Mains, 12 news-triggered questions.

No practice question for this one; the card may still help an answer. Why: Lasting topic on file; seventh tranche brings 56 blocks auctioned. Mostly routine progress data, so no question likely.

Worth revising until Prelims 2028: most news questions come within two years of the event.

Environment

El Niño and the Indian Monsoon

GS1 Geography - ClimatologyPrelims and Mains

Why in news
On 22 June 2026, INCOIS released its first specialized El Niño bulletin for maritime sectors, warning of Indian Ocean heating, marine stress and a rough Bay of Bengal. The release was posted on 23 June 2026.
What it is
El Niño is the periodic warming of the central and eastern equatorial Pacific Ocean, part of the ENSO cycle. It weakens the Walker circulation and usually reduces Indian summer monsoon rainfall. The India Meteorological Department, under the Ministry of Earth Sciences, issues the official monsoon forecasts.
First Stage forecast
IMD's first long range forecast, issued on 13 April 2026, predicted below-normal rainfall at 92% of the LPA.
Second Stage forecast
The forecast was revised to 90% of the LPA, with El Niño conditions expected to develop.
El Niño onset
Weak El Niño formed in June 2026 and strengthened to moderate.
El Niño and monsoon link
In an El Niño event the Indian summer monsoon is generally weaker than normal, and the event's intensity decides how large the impact is.
Historical record
Of 16 El Niño years since 1950, 7 saw below-normal Indian monsoon rainfall.
Timing of the effect
The inverse relationship between El Niño and rainfall is stronger in the later half of the season, especially September.
No district risk study
The Ministry has issued no district-wise El Niño risk assessment or guidelines to States for 2026.
No 'Super El Nino' category
Neither the WMO nor IMD officially defines a 'Super El Nino'. The term is informal.
How strength is classified
El Nino events are classed as weak, moderate, strong or very strong by the size of sea surface temperature anomalies over the equatorial central Pacific.
2026 progression
El Nino was weak in June 2026 and became moderate in July 2026.
Outlook
It may reach the very strong category in October–December 2026, but its impact on India depends on coupled ocean–atmosphere conditions, of which El Nino is one factor.
Impact-Based Forecasts
IMD issues Impact-Based Forecasts and risk-based warnings daily, valid for 7 days, for disaster authorities and States.
Walker circulation
El Nino weakens the Walker circulation, an east-west atmospheric circulation over the tropical Pacific.
Peak of the event
The ongoing El Niño is expected to peak in winter, from November 2026 to January 2027.
Thermal stress
The Arabian Sea and Bay of Bengal are likely to face thermal stress, most in March-May 2027. This may bleach corals and cause marine heat waves.
Fisheries impact
Sardine and mackerel catches may fall as fish migrate or fewer young fish join the stock.
East and west coast contrast
The Bay of Bengal will stay rough in the monsoon, raising erosion and flood risk on the east coast. The Arabian Sea and west coast should be calmer.
Next bulletin
INCOIS will issue the next specialized bulletin in the second week of July 2026.
Parent body
INCOIS is the Indian National Centre for Ocean Information Services, Hyderabad, under the Ministry of Earth Sciences.

Don’t confuse with El Niño vs La Niña: El Niño is warming of the central and eastern Pacific and usually weakens the Indian monsoon. La Niña is cooling and usually favours it.

Don’t confuse with ENSO vs Indian Ocean Dipole: ENSO is a Pacific phenomenon. The IOD is the temperature difference across the Indian Ocean, and a positive IOD can offset El Niño's effect on the monsoon.

Don’t confuse with El Niño vs Indian Ocean Dipole: El Niño is a Pacific phenomenon. The Indian Ocean Dipole is a sea-surface temperature difference across the Indian Ocean; a positive IOD can offset El Niño's effect on the monsoon.

Don’t confuse with El Nino vs La Nina: El Nino is warming of the central and eastern equatorial Pacific and usually weakens the Indian monsoon. La Nina is cooling there and usually favours good monsoon rainfall.

Don’t confuse with El Nino vs Indian Ocean Dipole: El Nino is a Pacific phenomenon. The Indian Ocean Dipole is a temperature difference between the western and eastern Indian Ocean. A positive IOD can offset El Nino's effect on the monsoon.

Don’t confuse with INCOIS vs IMD: INCOIS gives ocean advisories such as sea state and fishing zones. IMD issues weather and monsoon forecasts.

Environment: Prelims tests bodies, programmes and the law behind them; Mains asks why plans fall short.

No practice question for this one; the card may still help an answer. Why: El Niño is an on-file topic; INCOIS bulletin on marine heat and fish catch adds a new angle. Concept is asked, but this release lacks testable facts.

Worth revising until Prelims 2028: most news questions come within two years of the event.

Monitoring
An Empowered Committee chaired by the Cabinet Secretary monitors it; District Collectors/Magistrates implement at district level.

Don’t confuse with PARIVARTAN vs Vehicle Scrappage Policy: The national Vehicle Scrappage Policy (2021) sets up scrapping and fitness rules for old vehicles. PARIVARTAN is a Delhi-NCR scheme giving financial incentives for replacing old trucks and buses.

Don’t confuse with PARIVARTAN vs PM E-DRIVE: PARIVARTAN is a Delhi-NCR scheme to replace old BS-IV trucks and buses; PM E-DRIVE is a national scheme promoting electric vehicles.

Don’t confuse with MoHUA vs MoRTH: MoHUA approved the guidelines, but MoRTH implements the scheme.

Don’t confuse with NCRPB vs CAQM: NCRPB is a statutory planning body that channels the funds. It is not the Commission for Air Quality Management.

Don’t confuse with OEM discount vs government incentives: The 8% discount comes from the manufacturer. Interest subvention and fuel vouchers come from the Centre. Tax and registration relief come from states.

Don’t confuse with BS-IV vs BS-VI: These are Bharat Stage emission norms; BS-VI is stricter. India moved directly from BS-IV to BS-VI in 2020.

Schemes: 52 Prelims questions since 2013, 10 in Prelims 2026 alone. They test features, the period and who funds it. In Mains, 33 news-triggered questions, mostly GS3.
