Orla Mining Reports First Quarter 2026 Gold Production
Mexico’s Best Copper Drilling Intercepts, First Quarter 2026
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.

Teck to Release First Quarter 2026 Results on April 23, 2026
Mexico’s Best Silver Drilling Intercepts, First Quarter 2026
Nineteen companies released silver results from twenty drilling programs in Mexico during the first quarter of 2026. The highest silver intercept is from Luca Mining’s Campo Morado project in Guerrero, with 135.7 m averaging 77 gpt Ag. 1,833 gpt Ag, including a 0.55 m subinterval just over 7,500 gpt Ag. The underground diamond drilling campaign results are from the Largo Norte Zone, near current mining operations in this volcanogenic massive sulfides deposit (VMS).
Eighty percent of the projects in this table correspond either to intermediate or low sulfidation epithermal mineralization systems. The more numerous are those of intermediate sulfidation affinity, including La Colorada (Zacatecas), Alamos Silver, Cusi, Columba, La Preciosa, San Acacio, Las Coloradas, San Agustín and Tahuehueto. Intermediate sulfidation but probably distal to a porphyry copper system is Gran Pilar, in Sonora. Cruz de Plata presents both intermediate sulfidation and low sulfidation discrete zones of mineralization. Low sulfidation epithermal systems in the list comprise Yoquivo, La Virginia, Claudia and Copalquín, while Panuco present mainly low sulfidation mineralization with some zones of intermediate sulfidation affinity.
The remaining entries are lone examples of their mineralization styles: Campo Morado, at the top of the table, is a volcanogenic massive sulfides (VMS) deposit, Cerro Las Minitas presents skarn and carbonate replacement (CRD) mineralization, Adelita is a skarn distal to a porphyry copper system and Dios Padre a strongly zoned Au-Cu-Ag breccia related to a porphyry copper system.
Mexico’s Best Gold Drilling Intercepts, First Quarter 2026
Twenty one companies released results from drilling programs in Mexico during the first quarter of 2026. The highest gold intercept was at Heliostar’s Ana Paula project in Guerrero, with more than 55 m averaging 9.71 gpt Au, including a 10.9 m subinterval over 38 gpt Au. Ana Paula, which is part of the Guerrero Gold Belt, presents skarn and replacement mineralization with significant gold in sulfide rich breccias, with an uncommon late epithermal overprint. Other projects displaying skarn mineralization include Adelita in Sonora and Cerro Las Minitas in Durango. The only volcanogenic massive sulfides (VMS) deposit in the list is Campo Morado, in Guerrero, which attained a well-deserved second place with its long multigram gold intervals.
Epithermal systems represent 70 percent of the entries in the table below. High sulfidation deposits are the least numerous within the epithermal cohort in Mexico, but when economic, tend to be reasonably big and present in clusters. The three deposits here: Halcón, Cerro Pelón and Puerto del Aire (PDA) are in the Mulatos District in Sonora, and within the six top positions in the table. Intermediate sulfidation epithermal deposits are the most numerous, although more common in the lower part of the table, and include Tahuehueto, La Colorada (Zacatecas), Cusi, La Preciosa, San Acacio, Alamos Silver and Las Coloradas. Low sulfidation epithermal deposits include La Virginia, Yoquivo, Copalquín and Claudia. Cruz de Plata presents discrete intermediate and low sulfidation mineralization, while Panuco is dominated by low sulfidation mineralization but presents locally intermediate sulfidation characteristics.
Orogenic gold deposits are represented by EP (El Plomo) and La Unión, (proposed here) in Sonora. Finally, Dios Padre, also in Sonora, is a strongly zoned breccia distal to a porphyry copper system.
Summarizing, seventeen of the twenty-four projects on the list are epithermal systems, three present some type of skarn mineralization, two show orogenic gold style characteristics, one is a breccia related to a porphyry copper system and one, the top of the list, is a volcanogenic massive sulfides deposit.
