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.
