Luca Mining Corp. (TSXV: LUCA, OTCQX: LUCMF, FRA: Z68) is making headway at its Campo Morado polymetallic mine in Guerrero State, Mexico, with new drill results that suggest both resource growth and fresh exploration potential. The company’s ongoing Phase One drill campaign is targeting near-mine expansion and underexplored zones, and early results are turning heads with thick, gold-rich intercepts and new zones of mineralization.
The first surface drillhole at the Reforma Deposit, CM-RF-25-001, intersected a robust 15.1 meters grading 11.9 grams per tonne gold equivalent (AuEq), which included 5.35 g/t gold, 187.5 g/t silver, 0.31% copper, 8.39% zinc, and 2.75% lead. This hole is part of a larger interval of 21.5 meters at 9.53 g/t AuEq, confirming the presence of high-grade precious and base metals that had been suggested by historical data but not tested since 2010.
Underground, drillhole CMUG-25-015 returned 4.5 meters of 12.2 g/t AuEq (0.36 g/t gold, 161 g/t silver, 7.16% copper, 1.82% zinc, and 0.12% lead) within a broader 11-meter interval grading 7.6 g/t AuEq. Other holes, such as CMUG-25-016, delivered 30.8 meters at 1.59 g/t AuEq, further highlighting the mine’s polymetallic nature and the potential for resource expansion near existing workings.
In total, 22 underground drillholes have been completed so far in the current 5,000-meter campaign, focusing on zones adjacent to current production areas and previously untested targets. These results will feed into an updated resource estimate and future mine planning.
Campo Morado is a sizable property, covering 121 square kilometers within the Sierra Madre del Sur mineralized belt. The mine hosts several volcanogenic massive sulphide (VMS) deposits, rich in gold, silver, copper, zinc, and lead. This year’s exploration marks the first major campaign since 2014, and the company is intent on leveraging its extensive database, which includes over 600,000 meters of past drilling and a suite of geophysical and geochemical data.
The Reforma and El Rey deposits, both located about a kilometer from the main mine, are of particular interest. Discovered in the 1990s, these gold-silver enriched zones were never included in the mine plan, as previous operators focused on the zinc-rich G9 deposit. With gold prices at record highs, Luca Mining is now aiming to bring these zones into production, potentially adding significant value to its resource base.
Luca’s approach is systematic, prioritizing targets based on geological, geochemical, and geophysical interpretations. Thirty-eight priority targets have been identified across the Campo Morado concessions, with many still undrilled. The company’s current surface program includes 2,500 meters of drilling at Reforma and El Rey, designed to confirm and expand resources and collect material for metallurgical testing.
The underground campaign, running in parallel, is focused on adding mineable resources close to existing workings and identifying new zones with high potential. The combination of historic data, new drilling, and modern analytical methods is expected to provide a strong foundation for updated resource estimates and mine plans.
Luca Mining Corp. is a Canadian company operating two wholly owned mines in Mexico’s prolific Sierra Madre belt. Campo Morado produces zinc, copper, gold, silver, and lead from an underground operation, while the Tahuehueto mine in Durango State is a newly constructed underground mine focused on gold and silver. Both assets offer considerable resource upside and district-scale exploration potential.
With a robust pipeline of drill targets and ongoing campaigns both underground and at surface, Luca Mining is aiming to unlock new value at Campo Morado. The focus on gold-rich zones like Reforma and El Rey could reshape the mine’s resource profile, especially in a strong metals price environment.
