Mexico’s Best Drilling Intercepts, Second Week of December 2025
Two companies published during this week results from drilling campaigns in Mexico.
Coeur Mining provided results from the 2025 exploration program at its Palmarejo complex in Chihuahua. Approximately 68,000 m of drilling were completed by eleven rigs across the 30,000 ha land package. The program successfully identified several growth opportunities, both near-mine and district-scale. The Hidalgo, Libertad and San José veins were extended along strike by 500 m, 300 m, and 150 m, respectively. Drilling confirmed the discovery of precious metals mineralization along 900 m of strike along the 4 km Camuchín-Escondida trend.
The following is an excerpt from the 2015 technical report: Mineralization on the Palmarejo Complex consists of epithermal, low- to intermediate sulfidation, silver-gold vein and vein-breccia deposits that exhibit vertical and lateral zoning…. characterized by pervasive silicification, quartz-fill expansion breccias, and sheeted veins. Multiple stages of mineralization produced several phases of silica, ranging from chalcedony to comb quartz, and two periods of silver-gold mineralization (Corbett, 2007). This strongly-zoned mineralization is characterized by pyrite, sphalerite, galena, and argentite (acanthite) deposited within the quartz vein/breccias at lower elevations and higher-grade precious-metals mineralization with fine grained, black, silver-rich sulfide bands or breccia-infill in the upper portions of the structures.
Impact Silver released further results from the underground drill program in the Santo Domingo zone of its Plomosas mine in Chihuahua. In the press release is the next description: Mineralization at the Plomosas mine occurs as zinc-rich Carbonate Replacement zones in three bedrock units – the Mina Vieja marble (Tres Amigos Zone), the Juarez limestone (Juarez Zone) and in carbonate layers within the Cuesta Shale (Santo Domingo Zone) – where structural ground preparation along these units accommodated concentrations of zinc, lead, and silver.
