Sus características son relativamente atípicas en comparación con el resto de los depósitos en México, considerando el modelo más aceptado de un pórfido de cobre. El Pilar es un yacimiento de cobre exótico hospedado en gravas del Mioceno, que rellenaron cuencas generadas durante el evento extensional Basin and Range. La mineralización de sulfuros hipogéncos aflora poco y está asociada con una brecha magmática ligada al emplazamiento de un plutón monzonítico fechado por U-Pb en zircones en ~75 Ma. La edad del depósito obtenida por Re-Os en molibdenita es de ~73.9 Ma, y las reservas se estiman en 0.36 Mt de cobre.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT El Pilar is a porphyry copper deposit located in the northern part of the state of Sonora, Mexico, at ~15 km from the border with USA, and about (40 km) from the town of Cananea, inside the most favorable part of the porphyry copper belt of the southwestern North America. Its features are relatively atypical when compared with the rest of the deposits in Mexico, considering the most accepted porphyry copper model. The El Pilar is an exotic copper deposit hosted in Miocene gravels, that filled basins generated during the Basin and Range extensional event. The primary sulfide mineralization is poorly exposed and is associated with a magmatic breccia, linked with the emplacement of a monzonitic pluton dated by U-Pb zircon at ~75 Ma. The age of the mineralization was obtained by Re-Os molybdenite dating in ~73.9 Ma, and the estimated resources are of 0.36Mt copper.]]></p></abstract>
