COAL - The estimated reserve of coal in Meghalaya is 576.48 million tones. The coal is suitable for use as fuel for heat and power generation, in producing iron, steel and gas and to make coke for metallurgical purposes. Total annual production of coal in the state is about 5.0 million tones.
LIMESTONE - Huge deposits of good quality limestone , cement to chemical grade are found in the southern part of Meghalaya from Jaintia Hills in the East to Garo Hills in the west. The total estimated reserve is 15,100 million tones.
CLAY - Large deposits of good quality lithomargic clay is found in Garo Hills and are high temperature resistant (about 17500c ) and can be used for furnance lining and boiler oil stills.
KAOLIN/CHINA CLAY - Small patches of kaolin or china clay occur in Khasi Garo and Jaintia Hills and can be utilized in white ware, porcelain and paper making industry.
GRANITE - Deposits of multi-coloured granite around Nongpoh, Mylliem and Mawkyrwat and black granite around Jenjalgre in west Garo hills are available which may be processed into table tops and wall/floor cladding.
Minor deposits of glass sand, quartz, feldspar, bauxite, rock phosphate, phosphatic nodule, gypsum, sillimanite and base metals/trace metals are recorded from different parts of the State. Mineralisation of uranium is recorded in different parts of the State which is under the domain of Atomic Mineral Division (AMD), Government of India.
