Here's the copper mine (http://www.themodernantiquarian.com/site/12344/bold_venture.html ). And I should have said the Bosnian Pyramid of the Sun - yes, you can find out about what's happening there - but not from an archaeologist. (Which is a pity considering the substantial remnants that are being excavated).
Many archaeologists are saddened by what is going on in Bosnia but they can't and don't suppress the info .I doubt there is a professional archaeologist who accepts the pyramid hypothesis anymore than they are likely to accept Osmanagic's , who is not an archaeologist , other ideas like the Mayans being Atlanteans who came from the Pleaides . Because something gets ignored does not mean it is suppressed .
