Nine companies released copper results from drilling programs in Mexico during the second quarter of 2025. The best copper intercept is from Axo Copper La Huerta project in Jalisco, with 15.40 m averaging 3.86% Cu. The company presented intervals drilled in in 2020 by another company and from its own 2023 campaign, for a total of 11,441 m. According with the technical report, mineralization is of iron oxide copper gold (IOCG) affinity: “Mineralization at the La Huerta Property is characterized by Cu-Fe sulphides (chalcopyrite and minor bornite), Cu oxides and abundant iron oxides (magnetite and specular hematite). Hydrothermal alteration is represented by sodic-calcic (albite, actinolite, epidote) and potassic (biotite, orthoclase) assemblages with minor chlorite, sericite and late calcite. These deposits occur closely associated with coeval Mesozoic intrusions as we observe in La Huerta …”.

Most copper produced in Mexico comes from porphyry copper deposits, but none of the properties in the table below display that style of mineralization. The El Limón Sur deposit is the second in the list and is part of a skarn system, while the third deposit is a volcanogenic massive sulfides (VMS) system at Campo Morado, both in Guerrero. There are four projects that display intermediate sulfidation epithermal mineralization: Alamos Silver in Sonora, Don David in Oaxaca, La Reyna in Nayarit and Pitarrilla in Durango.

The bottom two projects also present intermediate sulfidation epithermal mineralization, but in their case the mineralization seems to be distal to porphyry copper systems.
