Kazakhstan has 5 coal basins. Largest part of the coal reserves is found in the Karaganda and Ekibastuz coal basins. This sector is sustained by the confirmed coal reserves for over 100 years. Aside from the aforementioned natural resources, Kazakhstan also possesses considerable explored reserves of cobalt-nickel ores, rare metals (tungsten, molybdenum), stannum, rare earths, non-metallic minerals (potassium salt, vermiculite, wollastonite, zeolith, etc.) that are either developed at a smaller scale, or are pending development.
