Monitor year-end 2026 block model update and Q1 2027 resource/reserve estimate for potential mine life extension. The expanded drill program and positive grade continuity suggest Lindero's underground potential may add meaningful reserves, but no production or cost data was disclosed.
Price Chart
Executive Summary
Fortuna Mining Corp. reported infill drilling results at its Lindero Mine in Argentina, confirming gold mineralization extends significantly below the current reserve pit design. The 2026 program was expanded from 6,000 to 8,534 meters due to early success, with highlights including 0.96 g/t Au over 350 meters (hole LDH-272) and 0.85 g/t Au over 236 meters (hole LDH-259). An updated resource/reserve estimate is planned for Q1 2027, supporting a revised life-of-mine plan.
Key Facts
- 2026 infill drill program expanded from 6,000m to 8,534m (31 diamond holes) due to early success
- Hole LDH-272: 0.96 g/t Au over 350m from surface, including 98m averaging 0.91 g/t Au below current pit design
- Hole LDH-259: 0.85 g/t Au over 236m from surface, including 94m averaging 0.66 g/t Au below pit design
- Gold mineralization extends vertically >300m below surface; zone remains open at depth
- Updated block model and pit design targeted by year-end 2026; revised resource/reserve estimate planned for Q1 2027
- Gold grades consistent with or higher than block model estimates per SVP Technical Services
Financial Impact
No financial figures provided; exploration results support potential mine life extension and resource upgrade at Lindero
Risk Factors
- Updated resource/reserve estimates may not confirm economic viability of deeper mineralization
- No production or cost guidance provided; exploration success does not guarantee mine plan changes
- Forward-looking statements subject to permitting, metallurgical, and operational risks
