Mexico’s Best Silver Drilling Intercepts in 2025

/ Gambusino Prospector / Leave a comment

During 2025 thirty-four companies presented silver results from drilling programs in forty-five deposits located in eleven states.

GoGold Resources tops the table below with a 21.25 m interval averaging 2,077 gpt Ag from Los Ricos South in Jalisco, followed by Palmarejo, Pitarrilla, Plomosas-San Marcial, La Colorada, Campo Morado, La Preciosa, and Don David, all with grade*meter results over 10,000 gpt*m.

Epithermal systems dominate the list, with 34 out of 45 deposits in the list belonging to this category. Intermediate sulfidation epithermal deposits, the most common, include Los Ricos South (Jalisco), Pitarrilla (Durango), Plomosas-San Marcial (Sinaloa), La Colorada (Zacatecas), La Preciosa (Durango), Don David (Oaxaca), Columba (Chihuahua), Alamos Silver (Sonora), Zacualpan (Estado de México), El Tigre (Sonora), Cusi (Chihuahua), Los Gatos (Chihuahua), Tahuehueto, (Durango), Los Reyes (Sinaloa), Las Coloradas (Chihuahua), La Reyna (Nayarit) and Plomosas (Chihuahua). Intermediate sulfidation epithermal deposits with some evidence of low sulfidation mineralization comprise Cruz de Plata (Durango) and Panuco (Sinaloa), while Cristina (Chihuahua) and Gran Pilar (Sonora) are likely intermediate sulfidation epithermal mineralization distal to porphyry copper systems.

Low sulfidation epithermal deposits include Copalquin (Durango), San Dimas (Durango), La Colorada (Sonora), Santa Elena-Navidad (Sonora), Las Chispas (Sonora), Coneto (Durango), Claudia (Durango), Bolañitos (Guanajuato), Santa Elena-Luna (Sonora), Santa Elena-Santo Niño (Sonora), San Ignacio (Guanajuato) and El Cubo (Guanajuato). Palmarejo (Chihuahua), which displays the second-best intercept in second in the table, present mainly low sulfidation mineralization with local intermediate sulfidation style input.

Five of six skarn deposits, Media Luna, EPO, El Limón, ELG Underground and Media Luna West are part of the Guerrero Gold Belt, and only one, Bolívar is in Chihuahua. Cerro Las Minitas in Durango presents skarn and carbonate replacement deposit (CRD) mineralization. La Parrilla in Durango and Camino Rojo in Zacatecas present skarn, CRD and intermediate sulfidation epithermal mineralization styles.

Campo Morado in Guerrero is the only project present in the table that belongs to the volcanogenic massive sulfide (VMS) deposit classification.

Seventy percent of the silver intercepts of the table are sourced in four states: Durango (10), Chihuahua (8), Sonora (8) and Guerrero (6).

Mexico’s Best Gold Drilling Intercepts in 2025

During 2025 thirty-two companies presented gold results from drilling programs in forty-three deposits located in eleven states.

Heliostar Metals topped the list with an 83.2 m intercept at Ana Paula that averaged 17.30 gpt Au. Six of the first seven positions in the table below are from deposits located within the Guerrero Gold Belt. These are mostly skarn deposits and include Ana Paula (a complex deposit mineralization-wise), EPO, ELG Underground, El Limón Sur, Media Luna and Media Luna West. Other deposits with skarn affinities include Cerro Las Minitas and La Parrilla in Durango and Camino Rojo in Zacatecas, although also presenting carbonate replacement deposits (CRD) mineralization.

The most numerous deposit types in this table of gold drill intercepts are within the epithermal category, evenly split between the low and intermediate sulfidation divisions. Low sulfidation epithermal deposits include La Colorada (although some doubts remain on this one), Las Chispas, Santa Elena and Cecilia in Sonora; Palmarejo in Chihuahua (with minor local intermediate sulfidation input); Copalquin, Claudia, Coneto and San Dimas in Durango; San Ignacio, El Cubo, Bolañitos and Valenciana in Guanajuato; Panuco (also with intermediate sulfidation epithermal mineralization) and Los Reyes in Sinaloa and Los Ricos South (along with minor intermediate sulfidation mineralization) in Jalisco.

Intermediate sulfidation epithermal deposits in the list comprise Alamos Silver and El Tigre in Sonora; Columba, Cusi, Las Coloradas and Los Gatos in Chihuahua; Cruz de Plata (also with low sulfidation epithermal mineralization), Tahuehueto and La Preciosa in Durango; Plomosas-San Marcial in Sinaloa; La Colorada in Zacatecas; Zacualpan in Estado de México; Don David in Oaxaca and La Reyna in Nayarit. Other two deposits present intermediate sulfidation epithermal mineralization, but are probably distal parts porphyry copper systems: Gran Pilar in Sonora and Cristina in Chihuahua

Campo Morado in Guerrero is the only volcanogenic massive sulfide deposits drilled during 2025 with results published by the companies involved. Geographically, 53% of the deposits with gold results in drilling campaigns are in three states on the north of the country, Sonora, Chihuahua and Durango, while 16% are located in Guerrero.

ON MEXICO ISSUES

  • Editor’s Commentary: Mexico The Mexican mining industry is enduring challenging times, battling an in-house restrictive regulatory environment while precious metal prices break all records in the World scene. Unfortunately for Mexico, the present government has in its DNA dogmatic ideologic chains that prevent really positive changes, immersed as it is in its quest to centralize power. Good examples on this endeavour are the recently approved law on water rights, which heavily restricts the granting and exchange of extraction permits, and the intention to change the electoral law in order to make it more difficult for the opposition to challenge the MORENA party rule. The current administration regulatory environment in mining is not good, or even clear, but it has to be said that it is better than under the past administration and that the president seems to have the will to improve it. While the rule book for applying the 2023 law in mining is still being drawn, long awaited permits that allow for open pit expansions and tailings dam construction have begun to flow. Reflecting the overall global economy uncertainties and higher commodity prices, 2025 ends with an optimistic mood for the worldwide mining industry with some of that optimism spilling over into the Mexican side by means of a steady inflow of funds during the last few months to the coffers of  junior companies with properties in Mexico. Expect more drilling in 2026, and the development of some properties that have been on the shelves for some time now.
