Mosaic Minerals Announces Start of Exploration Work on Its Golden Island Gold Property
Mosaic Minerals Advances Golden Island Exploration with Summer Campaign and Pilot Plant Testing

Executive Summary
- Mosaic Minerals Corporation initiated its summer exploration campaign on the Golden Island gold property in Quebec on June 16, 2026.
- The campaign runs through July 2026 and focuses on preparatory ground clearing, GPS surveying of historical infrastructure, underground gallery evaluation, and a mini-bulk sampling program (~500 kg) to assess coarse gold dynamics via pilot plant processing.
- Historical 1982 drilling and recent 2024 surface sampling have identified strong gold targets, with recent surface samples returning up to 101.19 g/t Au, guiding the current exploration focus along a major NW-SE magnetic anomaly.
- No new drill results, resource estimates, or financial metrics were disclosed in this release.
Material Impact
- The announcement confirms execution of the exploration plan previously funded by the December 2025 private placement.
- It represents a procedural, on-schedule step toward resource definition rather than a transformative event.
- The mini-bulk sampling program is a logical technical follow-up to the high-grade surface samples, aimed at understanding ore processing characteristics before committing to larger-scale drilling or development.
- The news does not introduce new valuation drivers, unexpected catalysts, or material changes to the company's risk profile.
