Please look at the State Inspection Report for Abandoned and inactice Mines Southern Idaho silver City war eagle report.Thats a good place to start.It shows most all operations on the top of the mountain from the Sinker up which is the last 2000' of the mountain.You will find that the mountain is like swiss cheese with different tunnels and operations etc.Many pictures.Not many water samples I agree but it shows and tells about the metals that pollute the ground water which has risen 1100' to the top of the mountain.1100' of water means that the psi at the bottom of these tunnels are nearly 500 psi.Anyways enjoy the reading as I did.
