Abstract

The Late Cretaceous Pebble Cu-Au-Mo deposit is a large Cu and Au resource in a belt of Cu and Au deposits in Southwest Alaska. This study presents precise ⁴⁰Ar/³⁹Ar igneous and alteration ages and a Re-Os mineralization age from the Pebble deposit as well as an alteration age from the Tertiary Sill epithermal Au-Ag deposit, which is less than 5 km from the Pebble deposit. These data have utility in regional exploration modeling and provide an opportunity to relate the timing of intrusion to alteration and mineralization.
