Mirasol Provides Exploration Update on Sobek Copper-Gold Project in the Vicuna District, Chile

Mirasol monetizes non-core assets to fund modest Sobek exploration as drill results remain incremental.

By The Northwire Desk — AI Analysis Jun 22, 2026 · 07:00 MRZ · 0.35 Mirasol Resources Ltd.
Executive Summary
  • Mirasol Resources released an exploration update on June 22, 2026, covering the second drill hole at the 46 South target of its flagship Sobek Copper-Gold project in Chile's Vicuña District.
  • Hole S46-DDH-002 intersected low-grade but structurally controlled mineralization: 4.50 m @ 0.07 g/t Au, 223 ppm Cu; 3.00 m @ 0.14 g/t Au, 188 ppm Cu; and 3.72 m @ 0.16 g/t Au.
  • Management elevated the VN-Zone as a high-priority drill target following IP-PDP geophysics showing a strong resistivity contrast.
  • The Green Wall domain is being re-evaluated as a potential copper-rich system, with prior rock chips showing up to 14.7% Cu.
  • Future work will focus on follow-up drilling at VN-Zone and Green Wall to define structural and geochemical controls.
Material Impact
  • This is an exploration update, not an earnings release. It contains no new financial results, guidance changes, or financing announcements.
  • The intercepts are consistent with early-stage, structurally controlled mineralization in a district known for high-grade porphyry/epithermal systems. However, the grades remain sub-economic for near-term development.
  • The market has already priced in the lack of a major discovery, as evidenced by the stock's decline from the January high of $0.88 to the current $0.35 range. The news is Routine - Neutral.
