The joint venture mine sites are located on the south side of the Mandalay-Mogok road, along the banks of the Yebu creek, by the Mintada bridge.
At the mining site rubies
and blue sapphires
of low-medium quality are recovered from the alluvial deposits, using mechanized open-pit and myaw-dwin
mining methods. Some of these gems are of high quality, but their weigh seldom exceeds 2-3 carats. Star ruby
of medium quality, spinel
are frequently found. In 2001 the mines were closed.
