The 50 km2 Monywa copper district lies near the Chindwin River within the northward continuation of the Sunda-Andaman magmatic arc, and 110 km west of the city of Mandalay.
High-sulphidation epithermal copper deposit(s), hosted in a series of Cenozoic sedimentary clastic rocks and Late Miocenic felsic to intermediate volcanic rocks (andesite or dacite porphyry intrusions).
Most mineralization is structurally-controlled with digenite-chalcocite in breccia dykes, in steeply dipping NE-trending sheeted veins, and in stockwork and low-angle sulfide veins.
The deposits were discovered by drilling starting in 1959. The mine was started in 1984 (1983 according to Mitchell et al. 2011, as a small open pit at Sabetaung), is owned by No. 1 Mining Corp. (sic) and operated by a 50/50 joint venture of Ivanhoe Mining and the military regime.
