The area is located NW of Pingu-taung. The general mining area is known since the last century. Rubies
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
are frequently recovered from the alluvium.
