S & K Mine (Monywa Mine), Monywa, Monywa District, Sagaing Division, Burma (Myanmar)

Latitude: 22°15'N
Longitude: 95°5'E
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 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.
