Why in News?
- A significant zone rich in nickel, copper and platinum‑group elements has been discovered in the Bhalukona–Jamnidih block of Chhattisgarh. Deccan Gold Mining Ltd. has obtained the licence to explore this area.
About the Block
- The block is located in Mahasamund district, about 70 kilometres from Raipur, within the Sonakhan Greenstone Belt of the Bastar Craton.
- It lies in a Neo‑Archaean geological setting with mafic and ultramafic rocks such as gabbro, pyroxenite and meta‑olivine websterite.
- Sulphide mineralisation occurs up to 300 metres deep and includes pyrite, chalcopyrite and pyrrhotite.
- Adjacent to the Kelwardabri block (held by Vedanta), the area is poised to become a hub for strategic minerals.
Scientific Significance
- Geological Survey of India exploration (G4 level) confirmed the mineral potential. Geophysical surveys revealed a 700‑metre‑long mineralised zone.
- The site represents a complex volcanic and sedimentary history, offering insights into Earth’s early crustal processes.
- It is a high‑potential zone for nickel, platinum‑group elements, chromium and copper.
Importance of Ni–Cu–PGE Minerals
- Nickel: Used in stainless steel, aerospace components and electric‑vehicle batteries.
- Copper: Essential for electrical wiring, renewable‑energy systems and electronics.
- Platinum‑group elements: Platinum, palladium and rhodium are critical for catalytic converters, fuel cells and green hydrogen production.
- These minerals are indispensable for clean‑energy transitions, defence applications and advanced electronics.
- India currently imports most of these metals; domestic sources can boost self‑reliance and support the country’s critical minerals strategy.
Conclusion
The discovery in the Bhalukona–Jamnidih block enhances India’s strategic resource base. Careful exploration and sustainable mining can contribute to energy security and technological advancement.
