The area is located NW of Pingu-taung. The general mining area is known since the last century. Rubies and spinels are found embedded in different types of marble. Most of these rubies are of cabochon grade, fewer of faceted grade, and small in size. Rubies, spinels, blue sapphires and quartz are frequently recovered from the alluvium.Ref: Ted Themelis (2008) Gems and Mines of Mogok, p. 249
