Latest Drilling Results from the Campo Morado Polymetallic Mine Project in Mexico

Luca Mining Corp. announced the latest drilling results from its polymetallic mine project at Campo Morado in Guerrero, Mexico.

The drilling primarily consisted of 6 surface drill holes and 5 underground drill holes deployed at the Reforma deposit.

Based on the drilling results from the Reforma deposit and adjacent underground operations, Luca has begun expanding the gold potential of the Campo Morado project.

Key intersections include:

Surface drill hole CMRF25-07 intersected 37.2 meters grading 13.85 g/t gold equivalent (Au 5.87 g/t, Ag 367.5 g/t, Cu 0.53%, Zn 5.54%, Pb 2.57%) at a depth of 211.2 meters, including 6.2 meters grading 43.77 g/t gold equivalent (Au 20.81 g/t, Ag 1,484.20 g/t, Cu 0.82%, Zn 5.98%, Pb 4.58%).

Hole CMRF25-06 intersected 39 meters grading 10.05 g/t gold equivalent (Au 4.09 g/t, Ag 304.9 g/t, Cu 0.96%, Zn 1.27%, Pb 1.74%) at 191.6 meters, including 9.9 meters grading 28.32 g/t gold equivalent (Au 11.61 g/t, Ag 783.9 g/t, Cu 3.51%, Zn 4.56%, Pb 2.91%) at 218.6 meters.

CMRF25-03 intersected 5.0 meters grading 9.13 g/t gold equivalent (Au 3.56 g/t, Ag 196.28 g/t, Cu 0.70%, Zn 4.43%, Pb 2.24%) at 285.5 meters.

Hole CMRF25-02 intersected 7.45 meters grading 12.59% gold equivalent (Au 6.91 g/t, Ag 228.06 g/t, Cu 0.37%, Zn 2.29%, Pb 4.75%), including 3.9 meters grading 19.78 g/t gold equivalent (Au 11.23 g/t, Ag 342.8 g/t, Cu 0.36%, Zn 3.95%, Pb 7.55%) at 273.8 meters.

These surface drill holes aimed to confirm the scale, continuity, and grade of the Reforma deposit. Results show that the intersected grades are comparable to or higher than previously reported results.

Underground drilling confirmed the grades and extensions in untested areas around the Southwest, Largo, and Bajo zones.

Among them, underground drill hole CMUG-25-022 intersected 5.5 meters grading 15.2 g/t gold equivalent (Au 3.20 g/t, Ag 252.6 g/t, Cu 2.19%, Zn 12.79%, Pb 5.10%) in an unmined area within 20 meters of current underground operations.

The Campo Morado project hosts several polymetallic massive sulphide deposits containing gold, silver, copper, zinc, and lead, forming part of the Sierra Madre del Sur mineral belt. This drilling campaign represents the first large-scale exploration since the mine commenced production in 2014.
