Naga Deng Copper Mine was a fictional location in India. It used to be the largest and deepest copper mine in the world, as mentioned by Satnam. The mine was converted into an underground neutrino scientific laboratory. Adrian Helmsley visits his friend Satnam Tsurutani in 2009. Satnam takes Adrian to the mine where he shows him his discovery. After the 2012 apocalypse, the mine was most likely destroyed when India was swept away by mega-tsunamis during the Worldwide Flooding. As a result of the apocalypse, the Naga Deng Copper Mine was left with extreme damage, along with the rest of India and is rendered uninhabitable.
