GoldHaven Reports Independent Review Confirming Large-Scale Hydrothermal System and Identifies High-Priority Drill Targets at Copecal
GoldHaven Validates Brazil Hydrothermal System Ahead of Phase II Drilling; Funding Secured for Magno Expansion

Executive Summary
- Independent Validation: An independent geological review has confirmed the Copeçal Project in Brazil as a large-scale, structurally controlled hydrothermal gold system.
- Target Vectors: The review identified clear vectors toward higher-grade mineralization at both East and West targets based on 9 holes totaling 1,085.7 meters from the inaugural program.
- West Target: Higher-grade enrichment associated with asymmetric to isoclinal fold structures; core of gold-in-soil anomaly remains largely untested.
- East Target: Confirmed northerly dipping shear-hosted mineralized zone with zoned sulphide assemblages (chalcopyrite–pyrite and chalcopyrite–bornite).
- Future Work: Phase II drill program scheduled for Q2 2026 to expand on these findings.
- Historical Context: Project features a ~6 km gold-in-soil anomaly originally identified by AngloGold Ashanti, which previously invested approximately US$1 million in exploration at the site.
Material Impact
- Validation of Thesis: The independent review serves as technical validation for the initial drilling results released in February 2026 (39m @ 0.11g/t Au). It reduces geological risk but does not introduce a new resource estimate or economic study.
- Funding Alignment: This news directly supports the $5.0M LIFE offering closed on April 30, 2026, confirming that proceeds will be used to advance the Copecal project as planned.
- Market Expectations: The market has already priced in the initial drilling success (stock rallied from $0.10 to $0.35 between Jan and Feb). This news confirms the next step (Phase II) rather than a surprise discovery, making it incremental rather than transformative.
- Dilution Context: While positive for project viability, the company has recently raised significant capital ($2M flow-through + $5M LIFE), increasing share count and dilution risk which offsets some of the technical upside.

Company Overview
- GoldHaven Resources Corp.: A junior exploration company focused on polymetallic projects in British Columbia (Canada) and Mato Grosso (Brazil).
- Magno Project (BC): District-scale polymetallic property (~37,200 ha) targeting silver-lead-zinc, tungsten, indium, and copper. High-grade surface samples reported up to 2,370 g/t Ag and 6,550 ppm W.
- Copecal Gold Project (Brazil): 100%-owned project in the Alta Floresta Gold Belt. Inaugural drilling confirmed gold anomalies; independent review validates hydrothermal system potential.
- Three Guardsmen Project (BC): Surface sampling returned copper grades up to 15.85% Cu, indicating high-grade skarn potential.
