RE:RE:South Korea hunts tungsten treasure - and a few quotes from the article......
The Sangdong mine is being modernised, with vast tunnels being dug underground, while work has also started on a tungsten crushing and grinding plant.
The Korean Mine Rehabilitation and Resources Corporation (KOMIR), a government agency responsible for national resource security, told Reuters it had committed to subsidise about 37% of Sangdong's tunnelling costs and would consider further support to mitigate any potential environmental damage.
