Gold discovered by AuEx Argentina (2007). Subsequent work by Minera Andes, Mariana, and Agnico Eagle. Magna Terra initiated the first drill program in 2019.

Systematic exploration work to date includes:

• Surface Geochemistry – 360 rock and float samples; 741 trench samples; 715 soil samples.
• Ground Geophysics – 17.6 km of Induced Polarization (IP) survey over 12 E-W lines; High resolution magnetometry survey (completed 2026) – confirmed and expanded 6 priority targets.
• Historical Drilling: 8 scout drill holes totaling 1,184 meters (Magna Terra 2019)
• Current Drilling Phase 1: 3,000-meter diamond drill program near completion by Lunex Metals (assays pending).
• Phase 2 Drilling: 3,000+ meters planned for the second half of 2026, to follow up on and expand on Phase 1 results.

December 2025 Work Program highlights:

• High-grade rock results: up to 13.26 g/t Au and 1,155 g/t Ag
• Vía Láctea corridor CONFIRMED → remains the #1 drill target (drill-ready).
• New upside unlocked: magnetics outlines additional major corridors + intersection zones, opening a second “Vía Láctea–style” system window and new priority targets.

Recent Work – Lunex Metals

• Intensive multidisciplinary campaign (3Q–2025): mapping, trenching, systematic & saw-channel sampling, geophysics
• Geological and conceptual exploration model refined
• Samples submitted for laboratory analysis

Magnetometry Update

• High-resolution survey confirmed and expanded the 6 targets
• An additional 2 high-magnetic bodies were identified, interpreted as magmatic–hydrothermal centers

Magna Terra 2019 Historical Drill / Trench results – Highlights:

• Cruz del Sur zone – Hole LR-DDH 002: 75m @ 0.62 g/t Au and 5.6 g/t Ag (from 37m) incl. 42.0 m @ 1.01 g/t Au and 4.6 g/t Ag.
• Cruz del Sur Zone – Hole LR-DDH 001: 51.4m @ 0.26 g/t Au and 9.4 g/t Ag incl. 2m @ 1.08 g/t Au and 79.6 g/t Ag
• Orion Zone – Hole LR DDH 006: 15.6m @ 0.11 g/t Au and 0.81 g/t Ag (ended in mineralization)
• Cruz del Sur Zone – Trench #2: 55m @ 0.41 g/t Au and 13,2 g/t Ag

2026 Phase 1 Drilling Program Summary

Geological Rationale:

• Targeting a low-sulfidation epithermal gold system.
• Mineralization controlled by the Vía Láctea Fault across the Cruz del Sur, Orion, and Estrella del Norte
• Hydrothermal fluids ascended along the structure.
• Pervasive silicification, selective replacement, and disseminated sulfides developed in volcaniclastic rocks of the hanging wall.

Drilling Program

• 16 diamond drill holes (DDH).
• Total meters drilled: 2,517.5 m.
• 9 holes at Cruz del Sur, 4 at Estrella del Norte, 3 at Orion.
• Average depth: 157 m
• Completed between February and April 2026.

Observations

• Widespread mineralization hosted in replacement bodies and hydrothermal breccia zones within favorable lithologies.
• Silicification, quartz-sericite alteration and argillic alteration consistent with the model.
• Late-stage veinlets indicating acidic overprint.
• System geometry controlled by the interaction of structure, secondary permeability, and lithological receptivity.
