Mineral Geology in BPSC Examinations:

After the creation of Jharkhand in 2000, Bihar retained distinct non-metallic, limestone, and strategic mineral reserves that are repeatedly tested in state examinations:

Gold Reserves at Sono (Jamui): The Geological Survey of India (GSI) confirmed Jamui district holds India's largest reserve of low-grade gold ore (approx. 222.88 million tonnes, ~44% of India's total gold reserves).
Limestone Hub: Rohtas and Kaimur plateau belts hold supreme cement-grade limestone (Vindhyan system) powering factories at Banjari and Dalmianagar.
Pyrites Monopoly: Amjhore in Rohtas district is the sole producer of iron pyrites (sulphur source) in India.
Mica Belts: Nawada and Jamui districts form the northern fringes of the historic Bihar-Jharkhand mica belt.

Exam View: Key Takeaways:

Gold Ore Reserves: Sono block, Jamui district (~44% of national reserves).
