Orosur Mining Inc Announces Infill Drilling Hits 104m @ 6.61g/t Au at Pepas

Executive Summary

• The latest three infill holes at the Pepas prospect returned high‑grade, surface‑starting intercepts: PEP047 = 104 m @ 6.61 g/t Au (including 36.6 m @ 10.23 g/t Au), PEP048 = 32.3 m @ 3.65 g/t Au (including 22.8 m @ 4.51 g/t Au), and PEP049 = 94.2 m @ 3.74 g/t Au (multiple higher‑grade sub‑intervals).
• These results continue the strong performance of the Pepas infill program, reinforcing confidence that a NI 43‑101 compliant Mineral Resource Estimate can be completed by year‑end.
• Soil sampling at the adjacent El Cedro porphyry prospect will resume this week after a weather‑related pause, supporting broader project advancement.

Key Details

• Pepas Hole PEP047 – Total interval 0–104 m @ 6.61 g/t Au; notable sub‑intervals: 5–41.6 m (36.6 m @ 10.23 g/t Au) and 83.05–98.45 m (15.4 m @ 10.30 g/t Au).
• Pepas Hole PEP048 – Total interval 0–32.3 m @ 3.65 g/t Au; sub‑interval 5–27.8 m (22.8 m @ 4.51 g/t Au).
• Pepas Hole PEP049 – Total interval 0–94.2 m @ 3.74 g/t Au; sub‑intervals: 0–6.65 m (7.27 g/t Au), 17.85–40.35 m (22.5 m @ 5.61 g/t Au), 61.55–82.15 m (20.6 m @ 5.04 g/t Au).
• Program Progress: Averaging ~1 hole per week with a single rig; rapid turnaround enabled by on‑site fire‑assay lab in Medellín (3‑4 day results).
• Future Work: Near‑term metallurgical, mining‑plan and logistics studies slated to commence once the maiden MRE is released.
• El Cedro Update: Soil sampling program, previously 1/3 complete, will restart this week after road repairs following a wet season interruption.
• CEO Comment (Brad George): “The latest results at Pepas continue to impress… we are increasingly confident that there is a commercially viable opportunity at Pepas and will very soon commence non‑drill related studies to advance Pepas toward development.”
