Mineral Deposits of Myanmar (1) Tin-Tungsten Deposits Although more than 122 mineral occurrences have been recorded (Goossens, 1978), only about ten can be economically worked as large and medium sized mines. The larger tin-tungsten mines in Myanmar are: - Mawchi, Heinda, Heinze, Hermyingyi, Kanbauk, Yadanabon, Kyaukmetaung and Nanthila mines, whereas Mawchi, Hermyingyi, Yadanabon and Nanthila mines work on vein deposits and the other work on placer deposits. (2) Lead-Zinc-Sliver Deposits 39 mineral occurrences are listed by Gossens in 1978. Out of these, only three are of economic important to be developed as mines. They are, in order of importance: Bawdwin, Yadanatheingi and Bawsaing mines. Lead mineralization occurred as massive type, disseminated type and stock work and irregular stringers in the host rock of epidotized rhyodacite porphyry of acidic volcanic rock. The strike length of the Vein No.1 is 172.ft long and it's average width is 4.4 ft wide. The ore reserve is 5,000 tons and average grade is 25% Pb. (3) Copper Deposits Out of 45 mineral occurrences of copper ore, only three are of some economic importance. These are: Monywa deposit (now producing by Ivanhoe Myanmar Holding Ltd. ), Shangalon deposit ( about 16 miles SW of Kawlin ), and Sabe-Taung deposit ( about 12 miles ESE of Kyaukse ). (4) Nickel and Chromide Deposits The Nickel deposits occur in close association with the Cretaceous-Eocene serpentinite bodies emplaced in northern Chin Hills ( Mwetaung ) and in northern Myanmar ( Innet-taung ). The chromide deposits are also associated with the serpentinized ultrabasic bodies. At least 13 chromide occurrences are known at Mwetaung and Tagaung Taung. (5) Manganese Maganese Boulder Floats Maganese Ore ( 48% Mn ) Residual Manganese deposit originated in muscovite schist (Mergui Group of Silurian to Permian age) will carry out production in the very near future.The ore reserve is 2.3 million ton with the grade of 15-30% Mn for low-grade ore and 40-48% Mn for high grade ore. Residual Manganese deposit originated in muscovite schist (Mergui Group of Silurian to Permian age) will carry out production in the very near future.The ore reserve is 2.3 million ton with the grade of 15-30% Mn for low-grade ore and 40-48% Mn for high grade ore. (5 ) Antimony Deposits Tin-bearing QV Small scale Antinomy mining in slate host Out of 30 mineral occurrences of stibnite listed by Goossens in 1978, only four have been developed as small mines. These are Thabyu, Lebyin, Natsan and Painchit mines. Mining of antimony ore in the slate host of Taungnyo Group of Permocarboni ferous age is carried out at Kadaik Area of Mon State. (6) Iron Deposits Out of 48 iron oxide occurrences listed by Goossens in 1978,
