The report records the GPS coordinates of each site, indicating that the inspections were supported by field-based verification.The department has clarified that no mining permission or permit for extraction of minor minerals or earth had been issued for any of the identified locations. To establish ownership of the land and confirm the relevant khasra numbers, the Revenue Department has been requested to carry out demarcation. Officials stated that further legal and administrative action will be initiated after the demarcation report is received.Till now, the administration action has been restricted to registering FIRs against unknown persons with no suspects identified or arrested.Criminal proceedings have been initiated under Sections 4(1) and 21(1) of the Mines and Minerals (Development and Regulation) Act, 1957. The report details several FIRs registered during July.One case at Dera Bassi relates to alleged obstruction of government officials during an anti-illegal mining operation, while another FIR at Handesra concerns the alleged unauthorised excavation of nearly 40.50 lakh cubic feet of earth from the Tangri river area. Separate cases have also been registered in connection with alleged illegal mining activities at Bijanpur, Peer Muchhalla and Ghadoli.During one inspection at Bijanpur, officials detected ongoing illegal excavation involving a JCB machine. However, the operator reportedly fled the spot with the machinery before it could be seized, leading to registration of a case against the unidentified accused. In another instance, police registered a case over alleged illegal extraction of gravel from the Ghaggar river near Peer Muchhalla.
