The list of the mineral companies was compiled and updated in June 2012 by EISEI network. All of the information were originally collected from mining provincial departments of the Ministry of Industry, Mines and Energy (MIME), and other sources from the network. The list records the total of 150 companies along with the company's address and nationality as well as geographical location, land size and mineral types of the operation. Nearly all of those companies were granted exploration licenses.
