Coal mining and deposits Coal mining and deposits<br />
19.4 Coal is mined on a small scale in Bhangtar in Samdrup Jongkhar and exported to neighbouring tea estates<br />
of India as well as Bangladesh. Detailed exploration has been carried out in Gerua and the Dimala Khola blocks on<br />
Bhangtar-Deothang road. So far, the area have not shown any indication of large coal deposits because of the<br />
tectonised nature of its occurrence. In Gerua block, a total reserve of 89,000 tonnes of coals has been estimated at<br />
50 metre depth from the surface. Assessments of coal deposits in other parts of Bhangtar are in progress.<br />
Dolomite miningDolomite mining<br />
19.5 Dolomite is mined by five private companies and exported to India and Bangladesh. Large dolomite<br />
deposits occur close to the border with India. Bhutanese dolomite has good export potential, as the quality of<br />
dolomite is suitable for use in steel, glass and magnesium metal manufacturing processes.<br />
Gypsum miningGypsum mining<br />
19.6 Gypsum is mined in Pema Gatshel for use in cement plants. In addition, gypsum is exported to India and<br />
Bangladesh.<br />
19.7 A quartzite mine is being opened in Chhukha for export of quartzite lumps to India and Bangladesh.<br />
Investigations of quartzite deposits have been given great emphasis in view of the establishment of Ferro Alloys<br />
Limited at Pasakha. The quartzite deposits at Tintale, Samchi have been found to be suitable for use by Ferro<br />
Alloys Limited. This enterprise is owned jointly by the Royal Government, a private Bhutanese company and a<br />
Japanese company. A total of 4 million tonnes of quartzite with silicon was proved by Geological Survey of India,<br />
Bhutan Unit, for this company.<br />
Limestone deposits and miningLimestone deposits and mining<br />
19.8 Limestone is mined for manufacture of portland cement and calcium carbide. There are three cement plants<br />
in Samchi Dzongkhag each with installed daily capacity of producing 400 tonnes, 100 tonnes and 30 tonnes,<br />
respectively. Investigations of Rongri area in Sarbhang has proved a deposit of cement grade limestone of about<br />
1.94 million tonnes. Bhutan Calcium Carbide Limited is developing the infrastructure to utilise this deposit. There<br />
is also a reserve of 4.012 million tonnes of cement grade limestone in Pagli extension area, which would feed the<br />
400 tonnes per day Penden Cement Authority. Gumtu Mini Cement Plant would require about 50,000 tonnes of<br />
limestones per annum and a reserve of 0.9 million tonnes of limestone was proved in Titi area for use by this Plant.<br />
A major cement plant will be established in the 7FYP: the Dungsum Cement Plant in Nanglam. A reserve of 2.8<br />
million tonnes of limestone has been proved in the Kangrazhi and Kurung Ri area of Nanglam which will be used<br />
by the Dungsum Cement Project.<br />
Base metal depositsBase metal deposits<br />
19.9 Investigations are in progress in Gongkhola, Tongsa for copper deposits. A borehole has indicated the<br />
presence of mineralised zone. Drilling in Burkhola in Sarbhang area for strategic minerals has shown a reserve of<br />
3.42 million tonnes of scheelite ore of varying quality.<br />
InstitutionsInstitutions<br />
19.10 The Department of Geology and Mines is under the Ministry of Trade and Industry and is responsible for<br />
geological mapping, mineral exploration and providing geoscience services required by other government agencies<br />
and the private sector mining companies. The Department of Geology and Mines works in close collaboration with<br />
Geological Survey of India, Bhutan Unit which is based in Samchi, Bhutan.<br />
19.11 The Department of Geology and Mines, as a matter of government policy, is not involved in mining<br />
operations. It is a support organization which provides information on mineral deposits to promote mineral based<br />
industrial development. It also provides geo-technical information to the Department of Roads, Department of<br />
Works and Housing, Department of Power for evaluation of engineering hazards and on questions of structural<br />
stability. The Department of Geology and Mines supplies lithological and structural information to the Ministry of<br />
