Situated near the town of Monywa (Burma), when you go by road to visit the caves of Pho Wing Thaun, you pass by antique copper mines which are run by an Australian company. But today there is still some copper on the slopes, which the inhabitants of the area live from. This is a process whereby water pouring cans causes become extremely acidic. Later that water is mixed with traces of copper and by a process of heating copper residues are extracted to then be sold. Whenever it has not rained much in SIAMTRAILS you pass by this road so you can see this unusual place.
