In 1999 there were 3 main areas for gem mining at Kin: Kin-ko-lan-bauk,
Kin-shu-taw and
Kin-kyauk-leik.
Rubies and
sapphires were recovered from the alluvium using several medium-to-large scale open-pit and
myaw-dwin mining schemes. In November 2001 these mines were closed but continued to work seasonably.
