But it is much more than just ZTEM. ZTEM indicating 6-7 Pebble size deposits in one thing. But couple that with the fact this is all part of a caldera system with typical known consistancies and the Pebble deposit is already proven to contain a wide array of economical copper and gold and you have basically a slam dunk.
Similar with Bonanza Hills. You can fly ZTEM over the entire U.S. and find many ore deposits I would assume, but until you have samples that indicate the presence of significant quanties of economical metal, it doesn't mean much. The presence of proven reserves at Pebble and a grab sample of high grade gold at BH, makes this an extremely compelling story stock at a measely 35 +/- mrkt cap.
Oh, and then there is the uranium which will eventually be put into play.
