'The note from the honourable minister for environment is self explanatory, along with it is a list of 12 mines which are operating without fulfilling the requisite conditions or without having obtained any clearances from other statutory authorities,' D'Souza has said.

The issue of illegal mining has been one of the main features of the monsoon session of the Goa legislative assembly. A high level committee appointed by the chief minister has also thrown light on several instances of illegal mining in the state.

The opposition has repeatedly alleged that several cabinet ministers were involved in illegal mining. Leader of opposition Manohar Parrikar had also alleged that nearly 18 percent of Goa's mining exports was fed by illegal mining.
