"Arizona Mining Review" covers breccia pipe uranium, USGS mineral resource plans

The June episode of Arizona Mining Review is now on YouTube at

The interview with Dr. Jon Spencer, Chief Geologist here at AZGS, about his new report on potential uranium-bearing breccia pipes in northwest Arizona is drawing a lot of attention.   He and his co-authors project one to two orders of magnitude greater numbers of collapse features, breccia pipes and corresponding mineral resources as currently known.

I also talk with former Pennsylvania State Geologist about USGS's revised  plans for mineral resource reports.  George led a panel discussion at the recent State Geologists Annual Meeting in Flagstaff, on mineral resources.
