Practically all the gold produced in India is obtained from the Kolar and Hutti gold fiels in karnataka.The gold occurs as auriferous quartz veins within the dark amphibolic rocks of Dharwar age. The gold lodes are believed to be of high temperature hydrothermal origin.

The Kolar Gold Fields, located in the state of Karnataka. This field was discovered in the late 1800s and produced gold until it was closed in 2001 due to high costs and low gold prices. The Kolar Gold Fields were once one of the deepest mines in the world, with miners descending as deep as 3,000 meters to extract the precious metal.

The Hutti Gold Mines in Karnataka, the Andhra Pradesh Gold Fields in Andhra Pradesh, and the Sonbhadra Gold Fields in Uttar Pradesh. These fields have produced significant amounts of gold over the years, with the Hutti Gold Mines being one of the largest and oldest in India, having been in operation since the 19th century.

In addition to these major gold fields, there are also numerous small-scale gold mines and artisanal mining operations scattered throughout India. These smaller mines may not produce as much gold as the larger fields, but they are still an important source of income for many people in rural areas.
