Executive Summary

• Tinka Resources provided an update on its exploration activities at the Silvia gold-copper project in Peru, where two drill holes have been completed and assay results are expected in early 2026.
• The company announced a strategic reassessment of the Colquipucro silver deposit, citing record-high silver prices and improved geological knowledge as drivers for re-evaluating the 2016 resource estimate.
• The release also details administrative changes, including the appointment of a new corporate secretary and the engagement of Oak Hill Financial for investor relations and capital market advisory services.

Key Details

• Silvia Project Drilling:
  • Two diamond drill holes (S25-001 and S25-002) completed at Area A of the Silvia NW project.
  • Hole S25-001: Drilled to 257 metres at a 55-degree west-dipping orientation.
  • Hole S25-002: Drilled to 258 metres at a 70-degree west-dipping orientation.
  • Both holes tested beneath outcrops of high-grade gold-copper surface mineralization (skarn and possible porphyry styles).
  • Assay results are awaited and expected to be disclosed in early 2026.
  • A third hole is currently in progress from a platform 100 metres north, with a planned depth of 450 metres.
  • A fourth hole is expected to commence in December 2025 for completion in January 2026.
• Colquipucro Silver Project Re-evaluation:
  • Company is reassessing the Colquipucro deposit, located 2km from the Ayawilca zinc project.
  • Previous 2016 mineral resource estimate: 14.3 million ounces (indicated) and 13.2 million ounces (inferred) at a silver price of $24/oz.
  • Current silver prices are greater than $60/oz (record highs), prompting the review.
  • Planned work includes geological reinterpretation and review of metallurgy/silver recovery assumptions.
  • Resource database includes 8,700 metres of drilling in 49 holes; deposit is up to 75 metres thick, potentially amenable to open-pit mining.
• Corporate Appointments:
  • Wilma Lee appointed as Corporate Secretary, effective December 1, 2025.

Notable Quotes

• "We are excited by the progress made so far with the initial drill program at Silvia, testing beneath skarn and porphyry-style gold-copper mineralization in surface outcrops. The first two holes are complete, and we eagerly await the assay results from the laboratory now expected early 2026." — Dr. Graham Carman, President and CEO
• "The Colquipucro silver deposit is somewhat of a forgotten asset within our portfolio... With silver prices having more than trebled and with our much improved knowledge of the geology of the Ayawilca district as a result of multiple studies, this is the perfect time for a reassessment of this project." — Dr. Graham Carman, President and CEO
