gold semi-precious and precious stones the department of mines and geology is engaged in the exploration and evaluation of mineral resources in nepal and compiles and publishes consolidated information on the among mining companies thereby reducing the operating costs of the mines and increasing tax revenues to the government, and the latter could lower the costs of water supply, energy, transportation, and ict services to other users, which may promote economic development in a region.oct 29, 2015 the importance of good communication systems for proper mining safety cannot be overstated.
