Mine Pit Lake chemistry

Hi All,
I have some interest in gathering data over chemical composition of mine pit lake especially for the dissolved base metal . I am looking for worldwide possible sites with Cu, Ni, Zn, Co with dissolved value over 1mg/l.
If anyone may provide first hand data or path to accept it, it would be very much appreciated.
Thanks
