Slide 4: Investment Thesis
Investment Thesis From partner-funded validation to 100% exposure and execution Carolina Rush has reset the Brewer story around ownership, control and next steps for discovery 100% ~US$2M 2 3,480 acres Brewer interest and partner-funded priority porphyry holes contiguous Brewer- operational control
Slide 5: What Changed
What Changed OceanaGold withdrawal reframes the opportunity; does not erase the technical progress Before Partner-funded earn-in was the lead financing/validation story Now Rush controls Brewer 100%; retains the 2026 technical work, and determines the next drill program Why OGC OceanaGold indicated
Slide 6: 2026 Accomplishments
2026 Accomplishments Stronger technical position and improved commercial foundation • 100% Brewer interest retained with approximately US$2 million of partner-funded exploration • Expanded Brewer-Jefferson position to approximately 3,480 contiguous acres • Two priority deep porphyry exploration hole
Slide 7: Brewer Ownership & Control

Slide 17: Interpretation and Next Steps
Interpretation and Next Steps Phase II Porphyry Targets Defined • Independent review by Dr. Richard Sillitoe supports the tilted porphyry copper-gold model • Hole 38 provides evidence that Brewer is potentially a gold-rich porphyry copper system • The program refined the target area toward the west/
