A documented mineral occurrence is not collecting permission. Sikkim Mineral Policy 2025 and the state minor-mineral framework regulate mineral extraction, quarrying and riverbed materials, while much of the state is ecologically sensitive, forested or high-altitude terrain. Verify land ownership, protected-area/forest status, mineral rights and site-specific permission before removing material.
