A CBI team today visited three prominent mining areas in Sandur here in connection with alleged illegal mining.
The five-member team from Chennai also later went to Belekeri in Uttara Kannada, officials said.
Belekeri was in the limelight over illegal export of iron ore from the port there, which was exposed by former Karnataka Lokayukta N Santosh Hegde.
In his report, Hegde had said 7.74 million tonnes of iron ore were illegally exported between 2006-07 and 2010-11, causing huge loss to the exchequer.
