A comparison of the hydrothermal alteration systems around the Mo-hosting White Pine intrusion, Utah, and the Buckingham Porphyry, Nevada
(2015)
The White Pine Fork Mo porphyry has an estimated resource of 16 Mt of Mo at 0.1%
Mo. The host intrusions are K-feldspar- and quartz-porphyritic monzo- to syeno-granites
characterised by LREE enrichment, fractionated HREEs ...
