INTERNATIONAL ACTIVITIES

In the past, GEOMIN staff members took part in a number of expeditions abroad, particularly focusing on the geological mapping, prospecting and exploration of deposits of mineral resources.

COMPLETED PROJECS

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

• 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.

• The aim of the project was revision of the present state of mining and beneficiation capacities at Khovd Gol wolframite deposit in western Mongolia. Re-evaluation of current ore reserves together with revision of ore grades of tailings have been performed in the frame of this project. Preliminary study of redevelopment of aproach to underground mining and project of construction of new gravity beneficiation plant have been also elaborated.

Technical and technological assistance in remediation of ecological loads arising from illegal gold mining within central part of Mongolia (2008 - 2010)

• Accounting of dangerous mining tailings in Bayankhongor aimak,
• Geoenvironmental investigation of old loads after mining within somans Baruunkharaa, Bornuur, Jargalant, Mandal, Sharyn Gol and Sumber,
• Reclamation and revitalization of Boroo locality,
• Operation of decontamination plant in Technology center in Bortolgoi city,
• Project of Technology center in soman Mandal.

• Drilling, hydrogeological and sampling work have been carried out in the frame of this project in order to specify intensity and extent of pollution of hydrosphere and geological environment caused by raw hides treatment factory (contamination mainly by metals, organic substances and oil products). Expoloration have been carried out in industrial zone of Ulaanbaatar on the banks of Tuul river. Indication and permanent monitoring wells have been deepened, hydrodynamics tests caried out and numerous samples taken of underground waters, soils and building constructions for chemical analysis. Geological structure of studied area have been characterized on the basis of gathered results. Project represents delivery for DECONTA a.s. company.

• Evaluation of reserves of underground water in fore-land of extended tailings pond after Cu and Mo ore treatment at Erdenet deposit. Evaluation of stability conditions of tailing pond dam in dependence on underground water pumping.

• Project represents delivery for Mendel University in Brno. The main task of hydrogeologists from GEOMIN company was to ensure water resources for irrigation systems in locality, where small plant production is carried on. Comprehensive hydrogeological and geophysical investigation survey have been carried out followed by deepening of new wells and their capacity verification by pumping tests. New water resources have been embodied into the system of irrigation of cultivated areas. Geological and hydrogeological work performed in the locality enabled to specify its geological structure, aquifer and complete evaluation of possibilities of use.
  

• In the frame of new water resources construction and putting into operation the specialists of GEOMIN company ensured subseqent management and optimization of using of individual types of irrigation systems applied in locality.

• The main target of project is to reduce participation of man and impact of his activity in desertic and semi-desertic areas of Suchbaatar province on ingoing process of desertification and to help to maintain traditional extensive forms of agriculture in sustainable extent. As contemplation was also ensuring of life conditions and development of county centers by improvement of drinking water supply. Project followed by its subject and location previous peoject „Sustainable development of water economy and and water resources management and desertification combat in Dornogobi region within south-east part of Mongolia“, carried out in years 2003 - 2006. New water resources have been prospected with help of geological and hydrogeological mapping, remote sensing and geophysical measurements. Drilling work, hydrodynamical tests, chemical analyses, construction of overground objects of water resources and their technical equipment have been carried out under the supervision of GEOMIN company specialists. The most important project output represent new and renewed water resources. Resources have been completly constructed so that target groups can use it without any next investments.Water treatment plant have been installed at three new water resources, located in county centers (Czech water tratment plants produced by W.P.E Běchovice company). After handing over of plant its provider was established and trained in handling, maintenance and protection. The same in the case of water treatment plants.

• The aim of this development project was to built new wells – deep boreholes – for the needs of supply of slums, herdsmen and their herds and boors by drinking and service water. Compilation of hydrogeological map of Erdenet city and its larger surroundings, engineering economy study of water supply of city and GIS as well as creation of databasis of all water resources in Orkhon aimak belong also to the project.

• The intent of project was identification and assessment of environmental risks resulting from tailings arising from illegal artisanal mining of gold deposits and ore dressing with the use of mercury and cyanides. Part of project represents research of soil and underground and surface waters contamination by mercury in egions with developed mining. The main project target is to implement long-term monitoring of manner of mining and ore dressing of placer gold deposits and to contribute to the improvement of environment protection within Selenge river catchement.

• Carrying out of geological survey and reassessment of raw material reserves of the important placer gold deposits within central Mongolia, recommendation of exploitation method and proposal of optimal implementation of health harmless gravitational technology.

• Hydrogeological evaluation, reconstruction of damaged shallow wells and identification of new deep water sources in Dornogobi region in south-east Mongolia.

• Assessment of impacts of Cu-Mo ores mining and processing procedures in Erdenet mine.

• Evaluation of basic regional information on the setting and geological development of this area. The work included carrying out of geochemical prospecting in the given area and prognostic evaluation of the region from the viewpoint of expected occurrences of ore deposits. Geological works were performed in the south-west part of Mongolia close to the border with the People´s Republic of China at an area of approx. 36 000 km².

• Identification and investigation of old environmental burdens in the area of abandoned Baganuur military base and identification of environmental risks resulting from the finished activities of Soviet army.

• Attending to environmental themes on the territory of the capital of Ulaanbaatar

• Identification and installation of new water sources in the centres of Chandmani and Erdene and Sangijn Dalaj districts in the municipalities of Talshand and Sangijn Dalaj in south-west Mongolia.

• Prognostic evaluation of Central Wollega area focused on occurrences of gold and base metals, followed by investigation of the selected promising area.
