Note:
Specimens labelled "Norbergite" coming from Oakssaung Hill has showed by analysis to be chondrodite or clinohumite. See messageboard at http://www.mindat.org/mesg-7-227088.html
Was discovered in 2003. Chondrodite marble and spinel marble are the principle rocks. The morphology of the area suggests that the gems were down from the highlands and accumulated at the bottom of the hill. Gem mining is illicit, and it is carried out in the loos (loo-dwin) and in myaw-dwin schemes where the following gems are found:
-Transparent, clean, light blue to greenish-blue, columnar, slender gem quality apatite crystals are found mostly as detrial. Apatite crystals of over 30 grams are known, and stones over 50 carats have been faceted.
-Bright blue sodalite found as boulders of varying sizes (pebble to fist size) associated with calcite characterized by concentric light blue spots. The material makes fine quality, large size, translucent cabochons.
-Light creamy monoclinic amphibole crystals associated with mica and other minerals.
-Hackmanite, chondrodite, spinel and diopside.
In 2004 at Phayar-taung, Myaw-taung and Kyini-taung uranium-bearing minerals were discovered. - Ted Themelis (2008) Gems and Mines of Mogok
