Orosur Mining Inc - Pepas Drilling Continues to Intersect High Grades

Executive Summary

• Orosur Mining reports assay results for five additional infill holes at the Pepas prospect, including a high‑grade intercept of 63.55 m @ 8.23 g/t Au (hole PEP060) and 49.95 m @ 4.29 g/t Au (hole PEP064).
• The program remains on schedule with a mid‑program review underway, supporting the goal of completing a NI 43‑101 compliant Mineral Resource Estimate (MRE) for Pepas by year‑end.
• Cumulative drilling to date (post‑MMA transaction) totals 53 holes, delivering multiple significant gold intersections that continue to define mineralisation margins and geological controls.

Key Details

• Hole PEP060: 63.55 m @ 8.23 g/t Au (overall); includes a higher‑grade sub‑interval of 37.5 m @ 12.99 g/t Au (24.85–62.35 m).
• Hole PEP064: 49.95 m @ 4.29 g/t Au (overall); includes a sub‑interval of 15.6 m @ 9.88 g/t Au (44.90–60.50 m).
• Additional holes reported with modest grades:
• PEP061 – 3.40 m @ 0.48 g/t Au
• PEP062 – 7.05 m @ 0.47 g/t Au
• PEP063 – 14.00 m @ 2.56 g/t Au (plus 7.00 m @ 1.21 g/t Au deeper)
• Mid‑Program Review: Orosur is conducting a review to ensure drilling remains on target for the planned MRE, with anticipated resource consultant site visit in early November.
• Overall Program Progress: Since acquiring full ownership of Anzá (SPA closed 28 Nov 2024), 53 holes have been drilled at Pepas; numerous high‑grade intervals (>5 g/t Au) have been intersected across the program.
• CEO Comment (Brad George): “Pepas continues to move inexorably forward. The NI43‑101 MRE process is rigorous, but all of the pieces are falling into place.”
• Project Context: Anzá Gold Project is 100 % owned by Orosur following the November 2024 SPA that bought out former JV partner Minera Monte Aguila (MMA). The project hosts three primary prospects – Pepas, APTA and El Cedro.
