RE:The complex structure of the PLS deposit
You basically get a blow out of mineralization at the unconformity and then the remainder is well behaved stratigraphically along the main graphitic fault offset. Some stratigraphy can act as barriers. The reason McArthur River was so prolific was because the thrust faulting occurred next to a footwall quartzite unit resulting in multiple graphitic offsets which were all essentially traps for uranium mineralization.
