Executive Summary

Date: April 28, 2026.
Headline: Results of Updated Mineral Resource and Reserves; Increases Consolidated M&I to 731koz Au and Inferred Resource to 653koz Au.
Key Announcement: Serabi Gold announced a significant update to its mineral resources across the Palito Complex and Coringa Mine following Phase 2 brownfield exploration.
Resource Growth:
- Consolidated Measured & Indicated (M&I) resources increased by 29% to 730,800 oz Au (from 567,400 oz in March 2025).
- Consolidated Inferred resources increased by 50% to 653,300 oz Au (from 434,700 oz in March 2025).
Reserve Update: Palito Complex 2P reserves rose to 228,400 oz Au (from 147,000 oz in April 2025).
Strategic Context: CEO Mike Hodgson states this represents approximately half-way to the growth target of 1.5 million ounces by end of 2026.
Technical Reporting: A new NI 43-101 Technical Report is expected within 45 days.

Material Impact

Positive Asset Revaluation: The 29% increase in M&I resources and 50% increase in Inferred resources materially increases the company's asset base without requiring new acquisitions. This validates the $9 million brownfield drilling program announced in late 2024/early 2025.
Validation of Growth Strategy: The news confirms management is on track to meet the stated goal of reaching a 1.5–2.0 Moz resource base by end of 2026. Current combined resources (M&I + Inferred) total ~1.38 Moz, indicating significant upside remaining in the second half of 2026.
Synergy with Recent Financials: This news follows closely on the heels of the April 14, 2026 announcement confirming debt-free status and $64.4 million cash balance. The combination of a stronger balance sheet and larger resource base reduces dilution risk and enhances enterprise value.
Not Unexpected but Significant: While exploration results were hinted at in September 2025 (high-grade intercepts), the formal reserve/resource update quantifies the success. It is not a "Game Changer" as it follows a known trajectory, but it is "Material - Positive" due to the magnitude of the increase relative to previous estimates.
