... collapsed. Late ore- and postore-stage sulfide minerals (pyrite, orpiment, and stibnite) from the Betze-Post and Meikle deposits in the Carlin trend and from the Jerritt Canyon mining district have Pb isotope characteristics similar to those determined in Getchell and Turquoise Ridge. This observation...

... the Turquoise Ridge underground mine. The pits were developed by 1993 and mining was completed by 1995. As open-pit mining proceeded, several drill holes intersected some gold-bearing veins and stockwork zones in a “traditionally” barren pillow basalt unit in which the shallow holes were generally terminated...

... of 43.9 ± 0.6 Ma (MSWD = 1.3; Fig. 5E ). Previous analyses of sample IT-10 of X porphyry from the 2,445-m level of the Turquoise Gulch underground mine yielded a 41.6 ± 1.2 Ma K-Ar biotite age and 41.8 ± 2.3 Ma U/Pb zircon age ( Cornejo et al., 1997 ). In our results, most zircons are slightly discordant...

... network of a porphyry copper deposit. Recent exploration trends target exotic deposits because they are amenable to heap leaching; their sulfide-free copper oxide ore is environmentally benign; and their common occurrence near existing mine infrastructure extends mine life.
