Colibri Engages TerraEye to Advance Targeting at EP Gold Project

Dieppe, New Brunswick--(Newsfile Corp. - September 24, 2025) - Colibri Resource Corporation (TSXV: CBI) ("Colibri" or the "Company") is pleased to announce that it has entered into an agreement with TerraEye, a provider of satellite remote sensing and AI-driven exploration solutions, to deliver an advanced targeting program at Colibri's EP Gold Project in Sonora, Mexico.

Accelerating Discovery with Satellite + AI

TerraEye will deploy a multi-sensor workflow—combining multispectral and hyperspectral satellite imagery, explainable AI anomaly detection, and artisanal-mining activity detection—to identify and prioritize high-potential gold targets across the EP Project. TerraEye's datasets will be integrated with Colibri's magnetic, gravity, and geochemical databases to generate refined exploration models and actionable targets.

The approach is designed to detect subtle geological and geochemical indicators of mineralization—even where vegetation obscures the surface—by:

• Building Bare Earth Composites (BEC) to minimize vegetation, sand, and clouds to expose soil/rock windows for analysis.

• Running mineral mapping (e.g., Spectral Angle Mapper, Mixture-Tuned Matched Filtering) and geological indices to highlight alteration, clays, Fe-oxides and other pathfinders.

• Interpreting structures and lineaments from terrain models to locate potential fluid pathways.

• Applying AI clustering and explainable spectral targeting to converge multiple lines of evidence into ranked target zones.

What TerraEye Will Deliver at EP

The program will deliver decision-grade exploration intelligence, including:

• Prioritized Target Portfolio - A ranked list of targets with clear rationales (spectral/structural/geochemical evidence), sized polygons and coordinates for efficient field follow-up.

• Professional Analytical Report - An executive summary for decision-makers and detailed technical sections for geologists, with maps and figures supporting each target.

• GIS-Ready Data Package - GeoTIFF rasters (mineral-match scores, indices, composites), lineament/structure vectors, and target shapefiles/GeoJSON with attributes.

• TerraEye Platform Access - A secure, private workspace to review layers interactively, toggle evidence, and collaborate on next steps.

Strategic Importance for EP

By fusing TerraEye's satellite-derived anomaly maps with Colibri's datasets, the program is expected to sharpen geological models, focus ground work and drill planning, and reduce discovery risk. In the Caborca Gold Belt context, the ability to detect structure-guided alteration and stress in vegetation provides additional evidence to prioritize targets.
