The article presents new data on geology, mineralogy, and geochemistry of porphyry-copper, gold-silver, and silver-polymetallic ore occurrences in the Kongin magmatic zone of the Omolon terrane and granitoids, associated with it. It has been demonstrated that petrology and the age of granitoids are similar to those in the OCVB Penzhina segment. Mineralization of the Kongin zone is very close to that of the OCVB, differing in relatively high Mo in porphyry-copper ores and prevalence of silver-polymetallic mineralization over gold-silver.

ABSTRACT Exploration for porphyry copper deposits beneath barren or poorly mineralized, advanced argillic lithocaps is becoming common­place; however, there have been few discoveries except in cases where the copper ± gold ± molybdenum mineralization has been partly exposed, typically as a result of partial lithocap erosion. At Valeriano, in the high Andes of northern Chile, completely concealed Miocene porphyry copper-gold mineralization was recently discovered beneath a lithocap. Here, the results of the staged drilling program that led to the discovery are summarized, with emphasis on the key geologic, alteration, and mineralization features that provided guidance. The final deep drill holes of the 16-hole program cut well-defined advanced argillic and sericitic alteration zones before entering chalcopyrite ± bornite–bearing, potassic-altered porphyry, with grades of 0.7 to 1.2% Cu equiv, at depths of ~1,000 to >1,800 m.

Significant Addition

With the publication of this collection of papers on porphyry deposits, SEG offers a signifıcant addition to its popular Compilation series. Introduced in 2007, the series brings together papers on a single theme, collected from the entire archive of Economic Geology and other SEG publications, in a searchable, digital format—on CD-ROM or, as is the case with the newest release, on a DVD. The porphyry compilation, organized by Editor David Cooke, was available at the Whistler 2013 Conference in September and can now be purchased online through the SEG bookstore (www.segweb.org/store). We include below the preface written by Cooke, which also appears on the DVD.
