Ruby and spinel were found in the alluvium.On the hilltop (22°56'03"N. 96°30'33"E. 1,158m ASL) blue sapphires and a smaller number of rubies were mined in the alluvium in an open-pit scheme. Some of these gems are of fine quality and attractive in appearance.

In May 1999, with the mines in full operation, ruby, sapphire, spinel, moonstone, quartz, apatite, zircon and schorl were recovered from the alluvium.
