Since 1997, GEOMIN has executed several significant projects of geological and geochemical mapping, environmental assessment projects and hydrogeological investigations.

Providing of new water resources for country areas Zalugiin Gol and Ulaan Tolgoi within larger surroundings of Erdenet city, Mongolia (2010 – 2012)

  • The development goal of project is to ameliorate life conditions of habitants living in the Zalugiin Gol and Ulaan Tolgoi areas near Erdenet city by deepening of new water wells – deep boreholes - and thus to contribute to the diminuation of habitants migration from this area to the province center. Part of project is compilation of water economy budget of territory and elaboration of water management plan of Orkhon province (aomag) and its center Erdenet.
