I have a close friend who has been talking with his grandma and they own land in colorado. Anyways they were home over the past few months and she said that during the 1930's or 40's a group came out to the property looking for gold. They didnt find gold but they found platinum. She said that she can remember the area where the platinum was found. I was wondering if I could get any links and information to anything about mining/finding platinum.....could an E-trac find it and if so what would the tone be...like gold...?? I know that the etrac is not the "tool" for the job but its all I have at this point. Any help would be awsome!!!!
