Understanding Critical Minerals and Their Strategic Importance
Defining Critical Minerals
Critical minerals are elements essential for economic development, national security, and emerging technologies. Their supply is vulnerable to disruption due to geological scarcity, geopolitical concentration, or lack of substitutes.
India has identified 30 critical minerals including lithium, cobalt, nickel, graphite, and rare earth elements. These minerals underpin electric vehicles, renewable energy systems, semiconductor manufacturing, and defense technologies.
Role in India’s Manufacturing Sector
The Geological Survey of India plans to start 227 projects focusing on various critical minerals in 2025-26 Critical Minerals of India: Complete Guide, Status, Policy (2025). This extensive exploration initiative supports the Make in India campaign by ensuring raw material availability for domestic manufacturing.
Critical minerals enable India’s transition toward high-value manufacturing sectors. Battery production, electronics assembly, and renewable energy equipment manufacturing all depend on secure mineral supplies.
Import Dependency and Self-Reliance Goals
India currently imports most critical minerals, creating vulnerability to supply chain disruptions and price volatility. India lacks advanced capabilities in extracting and processing minerals like lithium from clay deposits or recovering rare earths from e-waste Critical minerals: Goals and gaps.
The auction strategy addresses this gap by incentivizing domestic exploration and production. Reducing import dependency strengthens economic resilience while creating domestic employment opportunities.
Connection to Clean Energy Transition
Demand for nickel, cobalt, graphite, and rare earths increased by 6-8% in 2024, largely driven by energy applications such as electric vehicles, battery storage, renewables, and grid networks Executive summary – Global Critical Minerals Outlook 2025 – Analysis – IEA. India’s clean energy ambitions require massive mineral quantities.
The country’s target of 500 GW renewable energy capacity by 2030 necessitates secure mineral supplies. Solar panels, wind turbines, and battery storage systems all require specific critical minerals in substantial quantities.
Detailed Breakdown of the 23 Mineral Blocks
Mining Lease vs. Composite Licence Structure
The distinction between mining leases and composite licences reflects different stages of mineral development. Mining leases apply to blocks with proven reserves ready for extraction, while composite licences combine exploration and mining rights.
Mining Lease Blocks (4 blocks) offer immediate production potential. These blocks have completed geological surveys and feasibility studies, allowing faster commencement of mining operations.
Composite Licence Blocks (19 blocks) require initial exploration before mining can begin. This structure attracts entities with exploration expertise and risk appetite, enabling discovery of new mineral deposits.
Geographic Distribution and State Participation
The 13-state distribution ensures that mineral wealth development remains geographically inclusive. States receive revenue through statutory payments and premium bids, creating incentives for facilitating mining operations.
Central and eastern Indian states dominate the distribution due to favorable geology. However, the auction also includes blocks in southern and western regions, reflecting comprehensive national mineral mapping efforts.
Bidding Process and Eligibility Criteria
The auction follows a transparent, competitive bidding mechanism. Bidders propose premium percentages above the base price, with highest bidders winning blocks subject to technical qualification verification.
Eligibility criteria balance experience requirements with opportunities for new entrants. Financial capacity, technical expertise, and environmental compliance records factor into bidder evaluation.
Expected Timeline for Block Development
Revenue from these auctions accrues to respective State Governments Sixth Tranche of Critical Minerals Auction to Launch in Hyderabad, creating immediate fiscal benefits. However, actual mining operations typically commence 18-36 months after auction completion.
Composite licence blocks require additional time for exploration activities. Mining lease blocks can potentially begin production within 12-24 months, depending on existing infrastructure and regulatory clearances.
Infrastructure Boom: Maharashtra and Bengaluru Megaprojects
Maharashtra’s Infrastructure Investment Plan
