LUCA Identifies New Wide High-Grade Gold Zones at Tahuehueto Earlier this week, LUCA Mining Corp. (traded as LUCA.v or LUCMF for US investors), which is expected to produce 60,000-70,000 oz of Gold Eq in 2024 between its two mines, announced a crucial development at its Tahuehueto Gold Mine, confirming new high-grade gold mineralization over extensive widths.
This discovery involves shoots branching off the main Creston vein at Underground Level 23, one of the primary structures currently being mined.
The Tahuehueto mine is situated within the Sierra Madre Mineral Belt, an area rich in active and historic mines. Although still under development, the Tahuehueto mine is expected to start generating positive cash flows this year, in line with LUCA's strategy to enhance shareholder returns.
Detailed geological mapping and channel sampling at Level 23 have identified breccia ore shoots up to 20 meters wide. Some channel samples have revealed gold concentrations exceeding 20 grams per tonne (g/t Au).
These high-grade zones, previously identified in earlier drilling, are integral to LUCA's plan to increase production to 1,000 tonnes per day (tpd), a target anticipated to be reached in the coming months.
Since early 2022, underground development at Tahuehueto has advanced, focusing on access, dewatering, and initial mining at Level 23.
The pre-feasibility study for Tahuehueto highlighted maximum vein widths of 8.4 meters in the hanging wall and 6.5 meters in the footwall vein splays at Level 23.
Current measurements show comparable widths, with 4.9 meters in the footwall and 9.5 meters in the hanging wall, though vein geometries vary.
The footwall splay, extending along a 160-meter strike, demonstrates excellent continuity. Channel sampling of the southwestern extent of the vein-breccia zone—approximately half of the fully exposed footwall splay—indicates a lateral extension of 200 meters by 230 vertical meters based on diamond drilling.
This area remains open at depth and to the northeast and southwest, with these targets included in ongoing exploration.
