The Geological Survey of India (GSI) has highlighted the vast untapped potential of critical and strategic mineral resources in the North-Eastern region of India. According to the report and handbook titled “Geological Potential of North East India”, released during the 2nd North-East Mining Ministers’ Conclave, the region possesses substantial deposits of minerals that are increasingly important for the global transition towards clean energy, digital infrastructure, and defence manufacturing.The findings are strategically important because critical minerals such as Rare Earth Elements (REEs), graphite, vanadium, lithium, cobalt, and other associated minerals form the backbone of modern technologies including:
The report underlines the need to reduce India’s dependency on imported critical minerals by identifying and developing domestic reserves, especially in geologically promising zones of the North-East.
Arunachal Pradesh has emerged as one of the most promising mineral zones in India.
GSI established a vanadium resource of 13.79 million tonnes, marking India’s first major resource of this critical alloying element.
Vanadium is important in:
The discovery assumes significance in the context of India's clean energy transition and renewable energy storage requirements.
GSI also established over 17.89 million tonnes of graphite resources in Arunachal Pradesh.
Graphite is a key raw material for:
The report highlighted that these deposits may support downstream beneficiation and high-value industrial applications.
Promising REE anomalies have been identified across Arunachal Pradesh.
Rare Earth Elements are indispensable for:
The discoveries are strategically significant because China currently dominates the global REE supply chain.
GSI investigations in Assam identified:
The report also mentioned preliminary geochemical indications of lithium in Precambrian gneiss formations in Assam.
The findings indicate that Assam may emerge as an important source of:
Meghalaya possesses major reserves of:
The report identified West Khasi Hills as an important bauxite-bearing region.
These resources can support:
Nickel and cobalt associated with ophiolite complexes are being investigated through detailed geological studies.
GSI identified:
These resources have strategic importance for metallurgy, energy, and industrial sectors.
| State | Key Mineral Potential |
|---|---|
| Tripura | Hydrocarbons, modest solid mineral inventory |
| Mizoram | Hydrocarbons, clay, construction-grade materials |
| Sikkim | Small-scale copper, lead-zinc, graphite occurrences |
| Meghalaya | Limestone, coal, bauxite |
| Assam | Iron ore, silica sand, placer gold |
| Arunachal Pradesh | Graphite, vanadium, REEs |
| Nagaland | Nickel, cobalt |
| Manipur | Chromite, lignite |
The discoveries are highly significant in the global context because critical minerals are central to:
India currently depends heavily on imports for many critical minerals, especially from countries such as:
Development of indigenous reserves in North-East India can strengthen:
Despite the economic potential, large-scale mining in the ecologically fragile North-East raises important concerns related to:
Therefore, mineral extraction in the region requires:

Critical minerals are minerals essential for:
These minerals generally face:
Examples include:
REEs are a group of 17 chemically similar elements used extensively in:
China dominates global REE processing and supply chains.
Ophiolites are sections of oceanic crust and upper mantle rocks exposed on land. They are important because they often host:
