Another kimberlite pipe, possibly leading diamond, found in the Anantapur district during examination by experts from the National Mineral Development Corporation (CNMCD) and Hyderabad-based National Geophysical Research Institute (NGRI).

It is the seventh fireplace kimberlite to be discovered in the cluster Kalyandurg Anantapur district and has been labeled KL-7. Most diamonds are extracted from carrot-shaped formations known as volcanic kimberlite pipes.

NMDC and NGRI have been conducting explorations in 2300 sq. Km region Kalyandurg Anantapur district after renewing his prospecting license.

The examination was conducted by Abhijit Mukherjee, CB Verma and Suyash Jha NMDC with Dr. Babu EVSSK NGRI.

Arial surveys of the region, along with remote sensing, were conducted to explore with other tests.

Scientists said the subsequent drilling kimberlite suspicious region led to the discovery of kimberlite pipe near budik-wave in Anantapur district. Kalyandurg previous explorations have led to the discovery of six kimberlite pipes.

"Based on the current discovery, also an appropriate research strategy here for future kimberlite exploration in the area suggests" the scientists said.

Diamond mining has several stages to the provisions of the Mines and Minerals Act. These include obtaining permits recognition of the Department of Mines and Geology, followed by a prospecting license from the state government. Companies will have to obtain mining concessions by the government for access to the actual mining.
