    Special Project-1
    Inspection of Mining lease area
                The Directorate has proposed for inspection of all mining lease areas to verify whether the proper implementation of the lease conditions are made or not.

    • The inspecting officer will physically verify the leased area.
    • He will verify the documents like challans, stock register, sale register, excise duty paid on quantity, electricity bill in case of industry, and also milling test reports.
    • For checking the illegal mining, he will collect the intelligence report from the local area.
