HOUSTON, TEXAS (By Editors at Energy Analytics Institute, 7.Jul.2025, Words: 371) — Luca Mining Corp. announced analytical results from the first surface drillhole at the Reforma Deposit and the next 4 underground diamond drill holes of an ongoing 5,000m underground and 2,500m surface Phase One exploration drill program at the Campo Morado Polymetallic VMS mine in Guerrero state, Mexico.
Campo Morado hosts several polymetallic massive sulphide deposits containing gold, silver, copper, zinc, and lead mineralization within a highly prospective land package totaling over 121km2 within the Sierra Madre del Sur mineralized belt. This year’s underground exploration campaign represents the first substantive exploration the project and mine have seen since 2014, Luca announced on 7 Jul. 2025 in an official statement.
Highlights:
— surface drillhole CM-RF-25-001 intercepts 15.1m of 11.9 AuEq (5.35 g/t gold, 187.50 g/t silver, 0.31% copper, 8.39% zinc and 2.75% lead) at the Reforma Deposit;
— underground drillhole CMUG-25-015 returns assays including 4.5m of 12.2 g/t AuEq** (4.5m of 0.36 g/t gold, 161 g/t silver, 7.16% copper, 1.82% zinc and 0.12% lead) within a wider 11m of 7.6 g/t AuEq (0.32 g/t gold, 99 g/t silver, 4.20% copper, 1.63% zinc and 0.19% lead);
— 22 underground drillholes completed to date as part of a 5,000m Phase 1 program targeting near-mine resource expansion;
— unrealized mineral potential continues to be identified in underexplored zones – results to inform updated mineral resource and mine plans; and
— surface drilling continues at Reforma and El Rey with 5 drillholes completed to date at the Reforma Deposit – first exploration of these deposits since 2010.
Surface drillhole CM-RF-25-001 was collared within the central part of the Reforma deposit, intersecting 15.05m of 11.9 AuEq (5.35 g/t gold, 188 g/t silver, 0.31% copper, 8.39% zinc and 2.75% lead) within a larger 21.52m of 9.53 AuEq (4.24 g/t gold, 159 g/t silver, 0.38% copper, 6.24% zinc and 2.05% lead).
As the inaugural surface drillhole for Luca, it was designed to confirm the size, tenor, and grade of precious and base metals historically reported at the Reforma deposit and will help guide future exploration of untested gold-rich targets north of the high-grade G9 deposit and other currently producing areas on the Campo Morado property, Luca said.
