Capstone Mining, owner of the Pinto Valley copper mine in the Globe/Miami AZ district, expands on high-grade exploration findings in Mexico.  Hay Mountain is much closer to home for them.  I wonder if they might be aware of it, given they have money for exploration?  Maybe they are not "international" enough for BG given that they are a Canadian company.
