VANCOUVER, BC, July 7, 2026 /CNW/ - Luca Mining Corp. ("Luca" or the "Company") (TSXV: LUCA) (OTCQX: LUCMF) (Frankfurt: Z68) reports new assay results from its ongoing 2026 drilling program at the Tahuehueto gold-silver mine in Durango, Mexico.
Exploration drilling has continued to intersect high-grade gold mineralization in newly identified breccia zones, close to current mine workings, confirming continuity of breccia-hosted mineralization within the Creston vein system and highlighting the potential for near-mine resource expansion.
Highlights
High-grade intercepts from surface drill holes targeting the Creston Vein, including:
-
4.7 metres ("m") of 6.73 g/t AuEq** (3.35 g/t Au, 109.05 g/t Ag, 0.68% Cu, 0.20% Pb, 12.06% Zn) in hole DDH26-246 including 0.6 m of 14.80 g/t AuEq (9.21 g/t Au, 300.00 g/t Ag, 0.76% Cu, 0.35% Pb, 12.64% Zn)
-
4.5 m of 4.21 g/t AuEq (1.61 g/t Au, 140.07 g/t Ag, 1.25% Cu, 0.25% Pb and 0.48% Zn) in hole DDH26-SU-14
-
2.8 m of 6.90 g/t AuEq (3.03 g/t Au, 223.94 g/t Ag, 0.62% Cu, 3.47% Pb and 3.83% Zn) in hole DDH26-245
-
1.2 m of 10.37 g/t AuEq (2.09 g/t Au, 451.00 g/t Ag, 4.24% Cu, 0.29% Pb and 0.13% Zn) in hole DDH26-242
-
Drilling confirmed the continuity of mineralization in previously untested areas located 20 to 35 m below Level 20, extending known high-grade breccia zones at depth and further validating Luca's geological model
Intercepts exceed current mined grades and occur within development distance of existing underground infrastructure, supporting potential integration into the near-term mine plan
Verified vein-related mineralization at the Creston Vein in close proximity to current mining faces through the Termite drill program:
-
1.7 m of 13.27 g/t AuEq (8.92 g/t Au, 116.83 g/t Ag, 0.74% Cu, 7.19% Pb and 11.36% Zn) in hole TRT26-06
-
Two contracted diamond drill rigs are currently on site and in operation, one dedicated to underground drilling and one to surface drilling. A Luca owned and operated underground rig continues to define mineralization identified in the near-term mine plan. To date, Luca has completed 54 underground holes for 10,426 m and 25 surface holes for 4,599 m
"These latest drill results have identified a previously unrecognized extension of the high-grade breccia-hosted vein system currently being mined on Level 20." stated Paul D. Gray, VP Exploration. "Management's interpretation that mineralization continued below Level 20 has now been confirmed, with results exceeding our expectations. The first five drillholes into this previously undrilled area successfully intersected the down plunge extension of the Creston vein. Based on these encouraging results, an additional nine holes were added to the program to further define the potential of this target, each of which successfully intersected the structure."
