Antimony
Myanmar holds significant, largely under-exploited antimony deposits, primarily located in the Shan State, Kayah State, and the Tanintharyi Region. Key minerals include stibnite, often found in quartz veins within carbonate rocks. Major mining areas include the Lyhamyar deposit and Tha Byu deposit, with significant exports historically sent to Thailand
Key Aspects of Antimony in Myanmar:
Geological Context: Deposits are generally shallow, low-temperature hydrothermal veins, often associated with, and enriched by, weathering in Paleozoic-Mesozoic sedimentary sequences.
Key Locations:
Shan State: Southern Shan Plateau (e.g., Hopong Township), northern Shan State.
Kayah State:
Tanintharyi Region:
-
Production and Trade:
- Myanmar has acted as a supplier of antimony ore and concentrates.
- Significant exports go to Thailand and other markets like Japan.
- Production fluctuated, with a notable peak around 2012–2014, and recent active mining in areas like TachileikMineralization Types:
The deposits are classified into several types, often found in breccias and veins associated with fault zones. Minerals present include stibnite
