Mirasol readies Sobek's 46 South for November drilling

Executive Summary

• Mirasol Resources announces the 46 South target on its Sobek copper‑gold‑silver project as a high‑priority, untested drill target based on integrated soil geochemistry, ground IP‑PDP, airborne MT and magnetic surveys.
• The company will complete a deep‑vector IP and MT survey by mid‑October 2026 to refine target geometry and plans to commence the 2025 drill program in early November 2026.
• Soil assays show up to 275 ppm Cu, 37 ppm Mo and 88 ppb Au; rock chip samples return up to 1.0 g/t Au, 420 ppm Cu, 508 ppm Mo, confirming a strong mineralized system.

Key Details

• Target Definition: 46 South covers ~1.0 km × 0.7 km copper‑gold‑molybdenum anomaly; located on southern margin of a ~6 km × 6 km circular magnetic high and within a cylindrical MT resistivity/chargeability anomaly.
• Geophysical Highlights:
• Ground IP‑PDP shows chargeability increase from ~150 m to >600 m depth; resistivity core >5,000 Ω·m.
• Airborne MT anomaly starts at ~4,500–4,600 masl and extends deeper, analogous to known porphyry systems in the district.
• Soil Geochemistry: Max values – Cu 275 ppm, Mo 37 ppm, Au 88 ppb across the anomaly.
• Rock Chip Results: Up to 1.0 g/t Au, 420 ppm Cu, 508 ppm Mo from quartz‑veinlet and breccia samples.
• Structural Context: Target sits at intersection of north‑south & northeast‑trending structures crossed by northwest‑trending faults; these intersections coincide with the strongest soil anomalies.
• Survey Plan: Deep‑vector IP and MT survey to be deployed early November 2026 (launch) after completion by mid‑October 2026, aimed at refining shallow IP/res domains and deeper MT responses for drill vectoring.
• Drilling Outlook: First‑pass drill hole design will test the overlapping soil anomaly, chargeable/resistive bodies, and deeper MT response; drilling slated for early November 2026.
• Regional Setting: Sobek lies ~7 km west of Filo del Sol deposit and ~3 km southwest of NGEx’s Lunahuasi discovery; part of a north‑south trending mineralized corridor in the Vicuna district.
