The Tamil Nadu government has updated its District Mineral Foundation (DMF) Rules, replacing the 2017 regulations with new rules for 2025. These revisions aim to better benefit individuals and areas impacted by mining operations. Key changes include new penalties for leaseholders who contravene contribution norms, shifting from potential imprisonment to financial penalties. The rules mandate that at least 70% of the Trust Fund must be allocated to directly affected areas and high-priority sectors like health, education, and environment.
