A five member team, headed by CBI Superintendent of Police, Subramanyeshwar Rao, armed with samples of the iron ore from Belikeri port which was illegally exported to various countries, compared it with iron ore in AMC and DMS mining areas, CBI sources said.
CBI is being assisted by experts from Mines and Geology department, sources said.
Associated Mining Corporation and Deccan Mining Syndicate owned, by former Minister G Janardhana Reddy and his wife Aruna Lakshmi are facing a probe for alleged illegal mining following a Supreme Court directive.
AMC had transported 0.80 lakh tons of iron ore to Belikeri port from Ramgad mining area on March 23 last year, CBI sources said.
