...J. David Lowell Abstract Discovery of the orebody, a faulted segment of the San Manuel orebody, was based on recognition of: (1) a zonal pattern in which ore is marginal to a low-grade core with potassic alterations--the zone of highest intensity; (2) evidence for post-mineralization tilting of 45...

.... Working with cuttings from very deep churn drill wells in Arizona in 1965, Dave predicted that the San Manuel blockcaved porphyry copper orebody would have a deeply buried faulted off portion. The prediction was based on observed alteration and mineralization zoning at San Manuel and a much deeper...
