Its formational age is constrained at ~49 Ma by field evidences, crosscutting relationships and 40Ar/39Ar geochronology (Corral et al., 2016, Corral, 2021). The recent molybdenite Re-Os dates by Perelló et al. (2020) claim that ore is spatially and temporally related to the host volcanic domes at ~71 Ma. After a thorough review of the geologic, geochemical and geochronological data from the Cerro Quema area, it is concluded that the Re-Os dates of Perelló et al. (2020) are not representative of the Cerro Quema formational age. Their proposed formational age at ~71 Ma is significantly older than the age of the host rock (~67 Ma). Furthermore, they invoke a previously unrecognized regional-scale magmatic event solely based on their molybdenite Re-Os dates. Instead, the Cerro Quema genetic model discussed here, in which magmatic-hydrothermal fluids derived from porphyry copper-like intrusions associated with the Valle Rico batholith produced the Au-Cu mineralization at ~49 Ma, is consistent with the geology, geochemistry and geochronology of the Azuero Peninsula. 2021 otro 1405-3322 https://www.redalyc.org/articulo.oa?id=94370810018 https://www.redalyc.org/journal/943/94370810018/ https://www.redalyc.org/journal/943/94370810018/html/ https://www.redalyc.org/journal/943/94370810018/94370810018.epub https://www.redalyc.org/journal/943/94370810018/movil 10.18268/BSGM2021v73n1a121220 en http://www.redalyc.org/revista.oa?id=943 Boletín de la Sociedad Geológica Mexicana application/pdf Sociedad Geológica Mexicana, A.C.
