Ye-bauk-thar-yar (Ye-bauk-thayar), Mogok Valley, Mogok Township, Pyin-Oo-Lwin District, Mandalay Region, Myanmar
The mining area is situated just east of the Yebu-thapanbin-kyar gem mining area. In 1999 several joint venture companies were mining the sandy alluvium using lebin and open-pit mining methods. More than two-thirds of the gems recovered are rubies, fewer are blue and yellow sapphires, spinels and quartz. Dark red rubies with silk are also found, some of them were heated to lighten the dark red color, but without much success. Rubies and red spinels are also recovered from the nearby primary deposit by blasting out different types of marble.Ref: Ted Themelis (2008) Gems and Mines of Mogok, p. 221
