What brought SolGold to Ecuador in 2012 ? 1. Early 2012, SolGold management were tasked to identify a new world class Cu-Au opportunity. 2. Four employees of SolGold had a prior relationship with Cornerstone via a JV between Intrepid Mines and Cornerstone in southern Ecuador. 3. Some of the principa
Slide 7: Long History of Terrane Accretion
Long History of Terrane Accretion An important aspect of district selection was use of a terrane accretion model for development of Cu fertility (i.e. prolonged transient compression within arcs followed by extensional pulses). • Romeral Terrane (Cedial et al 2003): Timing of accretion poorly constr
