Drill Results
Barksdale Intersects High Grade Porphyry Copper Mineralization, Including Two Intervals of 0.93% Cu and 0.90% Cu over 60.96 Metres Respectively on Flagship Sunnyside Project
Barksdale Copper Intercepts Validate Sunnyside Porphyry Potential Amid Capital Raises

Executive Summary
- Date: May 4, 2026
- Event: Drilling Results (First four holes of 2026 RC program).
- Key Highlights:
- Hole SUN26-002R: 0.93% Cu over 60.96m and 0.90% Cu over 60.96m within a broader 0.45% Cu over 392.19m interval.
- Hole SUN26-001R: 0.29% Cu over 454.15m, including high-grade intervals (e.g., 2.75% Cu over 3.05m).
- Total drilling to date: 13 holes totaling 13,475 feet (4,107 meters) in the current phase.
- Context: Results confirm broad areas of shallow, high-grade copper-zinc-silver mineralization within the Sunnyside Monzonite Porphyry. Drilling paused for monsoon season, resuming September 2026.
Material Impact
- Positive Validation: The intercepts (specifically 0.93% Cu over 60m) are significantly wider and more consistent than previous Spring 2025 results (e.g., 0.78% Cu over 4.6m). This materially strengthens the case for a robust porphyry system rather than just narrow veins.
- Expectation vs. Reality: While drilling was anticipated following the March 2026 completion of Round One, the grade and width exceed the initial Spring 2025 follow-up data. The market had priced in some improvement given the stock run-up from $0.17 to $0.26 between January and April 2026, but these specific wide intervals provide a higher floor for valuation models.
- Capital Context: This news follows a period of intense capital raising (Feb/March 2026 financings totaling ~$6M CAD). The results justify the capital deployment by confirming the asset's potential to support future resource estimation and earn-in milestones with Great Basin Metals.
- Risk Mitigation: The confirmation of mineralization reduces exploration risk, but does not eliminate it (no resource estimate yet).
