Mawchi

Mawachi a location in the Bawlake district of the Kayah State (also called Karenni State) is a state of Myanmar and formerly in the Karenni States of Burma. In the 1930s, the Mawchi Mine was the most important source of tungsten in the world.

Mawchi contained the world's largest granite-hosted tin-tungsten vein system before WWII. Ore production from 1930 to 1940 amounted to 2000 to 6000 tonnes annually, which amounted to 60% of Myanmar's total production, and one third of the world's wolfram (tungsten). From 1980-2010, 25,000 tonnes of tin-tungsten (Sn-W) ore were produced. Mawchi is located in the Western Granite Province, composed of Cretaceous to Eocene I-type granites and S-type granites, dominated by ilmenite-series rocks of granodioritic and syenogranitic composition.^[1]^[2]
