Union Coal & Mines Minister G. Kishan Reddy, along with Arunachal Pradesh CM Pema Khandu, inaugurated the state's first commercial coal mine at the Namchik-Namphuk coal block in Changlang district on October 6, 2025. The mine has reserves of 1.5 crore tonnes and is expected to generate over ₹100 crore in annual revenue.

First allocated in 2003, the block faced decades of delays before being revived through a transparent auction process in 2022. A Bhoomi Poojan ceremony preceded the handing over of the mining lease. The launch included a '100-tree plantation initiative' to address environmental concerns. The project marks a significant step for the North-East's mineral sector development.
