Eight companies released copper results from drilling programs in Mexico during the first quarter of 2026. The best copper intercept is from Luca Mining’s drilling at Campo Morado in Guerrero, with 135.7 m averaging 0.88% Cu. The underground diamond drilling results are from the Largo Norte Zone, near current mining operations in this volcanogenic massive sulfides deposit (VMS).

For a short table like this one it is striking the diversity of mineralization styles present. The most common deposit type is intermediate sulfidation epithermal, of which there are three examples at the lower end: Tahuehueto, La Colorada (Zacatecas) and Alamos Silver. Mineralization at La Huerta is described as of iron-oxide-copper-gold (IOCG) affinity, Cerro Las Minitas presents skarn and carbonate replacement mineralization, whereas Adelita can be defined as a skarn distal to a porphyry copper system, and Dios Padre as a strongly zoned Au-Cu-Ag breccia related to a porphyry copper system.
