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.

CEO Comment

"

Our agreement with TerraEye for the EP Gold Project places Colibri among a growing group of

explorers adopting next-generation remote sensing and AI tools

," said Ian McGavney, CEO of Colibri.

"

By combining TerraEye's satellite analytics with our extensive exploration database, we expect to

sharpen our geological modelling, refine drill targets, and accelerate the path toward discovery

.

The EP Gold Project represents a

large and underexplored land package

, and we believe this

program will not only

confirm and strengthen the targets we already know

, but also highlight

new

areas with potential mineralization and even previously unrecognized historical workings

. To

date, Colibri has already identified

10 high-priority targets, of which only three have been drill-

tested

, and we are optimistic that TerraEye's work could expand this pipeline even further. This

additional actionable data will both validate our geological models and open up new opportunities for

exploration across the project

."

TerraEye Comment

"

Exploration teams don't need more layers—they need ranked, defensible targets they can act on

,"

said Marek Wilgucki, CEO of TerraEye. "

At EP we're fusing Colibri's magnetics, gravity and

geochemistry with explainable satellite analytics so every target comes with a clear rationale and

coordinates. Our goal is simple: shorten the loop from desktop insights to boots-on-the-ground

validation and 2025 drill decisions

."

Recent Examples of the Approach

TerraEye's methodology has been applied with other explorers to rapidly shortlist field-ready targets and

integrate with ground programs, including:

Kuya Silver - Bethania (Peru):

Regional (≈1,850 km²) reconnaissance produced explainable

spectral targets aligned with epithermal indicators; GIS layers delivered for QGIS integration.

Kuniko - Norway (EUSPA Demonstrator):

Bare Earth Composites and mineral mapping

enabled a desk-to-outcrop cycle in a few months, with early field validation of spectral targets.

About the EP Gold Project

The

EP Gold Project

, located near Caborca in Sonora, Mexico, lies within the productive

Caborca

Gold Belt

, host to some of Mexico's largest gold deposits including Fresnillo's La Herradura and Noche

Buena mines. Colibri controls 100% of the EP Project, which spans 4,766 hectares and is road

accessible via Federal Highway #2 and ranch roads.

To date, more than

13,800 metres of drilling

have been completed across Evelyn and Plomo, outlining

multiple zones of shallow gold mineralization that remain open along strike and at depth. Highlight

intercepts include

8 m @ 4.82 g/t Au²

,

15 m @ 2.36 g/t Au²

,

29 m @ 0.47 g/t Au²

, and broader

intervals such as

66 m @ 0.27 g/t Au⁴

and

27 m @ 0.23 g/t Au⁴

(Hole EVE23-198), starting near

surface and ending in mineralization.

Chip/channels have returned

high grades

from several targets, including:

Banco de Oro

: up to

298 g/t Au over 2.4 m underground³

, with additional values of

12.3 g/t

Au³

and

11 g/t Au³

.

San Perfecto

: up to

58.9 g/t Au⁵

and

47.3 g/t Au⁵

, with additional strong values of

32.1 g/t Au¹

,

16.65 g/t Au¹

, and

15.6 g/t Au¹

.

Only

3 of 10 high-priority targets

have been drill-tested, leaving significant exploration upside. The

project is fully permitted for drilling, with a new program planned for 2025.
