Comment to "Porphyry-related high-sulfidation mineralization early in Central American Arc Development: Cerro Quema deposit, Azuero Peninsula, Panama" by Perelló et al., (2020)

The Cerro Quema Au-Cu deposit is hosted by a dacite dome complex of the Río Formation, Late Campanian-Maastrichtian volcano-sedimentary sequence Panamanian magmatic arc. Its formational age constrained at ~49 Ma field evidences, crosscutting relationships and 40Ar/39Ar geochronology (Corral et al., 2016, Corral, 2021). recent molybdenite Re-Os dates Perelló al. (2020) claim that ore spatially temporally related to host volcanic domes ~71 Ma. After thorough review geologic, geochemical geochronological data from area, it concluded are not representative age. Their proposed significantly older than rock (~67 Ma). Furthermore, they invoke previously unrecognized regional-scale event solely based on their dates. Instead, genetic model discussed here, in which magmatic-hydrothermal fluids derived porphyry copper-like intrusions associated with Valle Rico batholith produced mineralization Ma, consistent geology, geochemistry Azuero Peninsula.
