Track Record of Creating Value in Colombia

Buriticá Mine

The Collective Edge

Founded Continental Gold which discovered, built and ultimately sold the largest gold mine in Colombia to Zijin Mining in 2020.

Well trusted, knowledgeable and successful management team in Colombia.

Sold for C$ 2 Billion to Zijin Mining in 2020

2024 production*: 323,000 ounces of gold

*Zijin Mining's 2024 annual report

Highly specialized talent in generating grassroot exploration targets has resulted in multiple discoveries.

Robust Colombian focused model that integrates the Company's business plan with all stakeholders in a "Collective" manner.

Large-Scale Operating Mines

* Since September 2022, eight licenses have been issued

in the country (four open pit & four underground) 6

Caldas: The Most Desirable Mining State in Colombia

500+ year mining history - Pro-mining area of Colombia

Industrial based economy with excellent infrastructure

High level of education Excellent security

7

Operating in an Established Mining Camp

Located Contiguous to a Multi-Million Ounce Producing Mine

Option to earn 100% interest in the Guayabales and San Antonio projects.

Located next to Aris Mining's multi-million-ounce Marmato project which is currently in construction.

District never consolidated until now despite a 500+ year mining history.

Abundant labor, hydro power and supportive government.

Guayabales and San Antonio fall within a multi-kilometre mineralized intrusion complex.

**Please refer to disclaimer slide #2 for cautionary statement.

Guayabales: Three Targets to be Drilled in 2026 (up to 100,000 Metres) 10 permitted & operating mines in a 3km area within an established mining camp.

Multiple discoveries made through reconnaissance drilling since 2022.

165,000+ meters of drilling completed.

Please refer to the appendix (pages 31 to 44) for the individual metal breakdown used in the metal equivalent grade calculation. 10

Deep Drilling Aligns with Potential Future Development

Please note that no engineering studies have been commissioned to assess the viability of the tunnel and that the image depicted is included for illustrative purposes only.

Please refer to the appendix (pages 31 to 44) for the individual metal breakdown used in the metal equivalent grade calculation. 11

Apollo System: Large-Scale & Growing; 115,000m (269 holes) Completed

One Large System with Two Different Host Rocks

• Breccia system with shallow bulk tonnage Au-Ag-Cu-W mineralization located above a deeper Reduced Intrusion Related System (Au-w/ minor Bi-Te)

• Hanging Wall Vein System: Sheeted veinlets hosted in porphyry rocks

  Up to 100,000m of Drilling in 2026 (Up to 14 rigs)

• Expand the high-grade Ramp Zone at depth

• Expand the Northern Apollo area

• Infill drilling ahead of initial MRE in mid-2027

  Excellent metallurgy

  Geologically similar to giant deposits:

• Telfer and Havieron (Greatland Gold)

• Winu (Rio Tinto)

• Marmato Mine (Aris Mining)

  Please note that no engineering studies have been commissioned to assess the viability of the tunnel and that the image depicted is included for illustrative purposes only. Please refer to the appendix (pages 31 to 44) for the individual metal breakdown used in the metal equivalent grade calculation.

  
  
  Ramp: Only ~20% of the Breccia's Circumference has been Drilled!

  • Only 385m of up to 1,500m of the outer breccia margin has been tested to date for Ramp Zone style mineralization

  • 2026 drilling will test the entire

    ~1.5 km outer circumference

    of the breccia body

  • Seven drill rigs dedicated to Ramp Zone in 2026

    Please note that no engineering studies have been commissioned to assess the viability of the tunnel and that the image depicted is included for illustrative purposes only. 14

    
    
    

    Ramp: 350m Vertical Drilled & Open; Highest Grades in Deepest Holes

    • 2026 drilling to test Ramp Zone over 600 vertical meters

    • Highest grades to date in the zone at the deepest elevations. Will it continue?
