Orosur Mining Inc - High Grades Continue Pepas, El Cedro Prospectivity

By The Northwire Desk — AI Analysis Sep 09, 2025 · 02:12 OMI · 0.445 Orosur Mining Inc.
OMI · Price

Executive Summary

  • Six additional infill drill holes at the Pepas prospect returned significant gold intercepts, including an unexpected high‑grade vein (PEP055) with up to 303 g/t Au over 1.9 m.
  • The Pepas MRE infill program is ahead of schedule and could be completed by late October 2025, moving the resource toward NI 43‑101 compliance.
  • Soil sampling at the adjacent El Cedro prospect shows widespread anomalous gold (≥0.3 g/t Au, with pockets >1 g/t Au), supporting a larger porphyry system and potential future drilling.

Key Details

  • Pepas Drill Intercepts
  • PEP054 – 20.6 m @ 2.01 g/t Au (incl. 6.5 m @ 3.29 g/t Au)
  • PEP055 – 47.25 m @ 15.25 g/t Au overall; includes a 1.9 m interval @ 303.25 g/t Au (two coarse‑gold samples: 465.71 ppm and 122.74 ppm, re‑assayed with consistent results)
  • PEP056 – 22.5 m @ 1.64 g/t Au (incl. 5.7 m @ 3.78 g/t Au)
  • PEP057 – 7.45 m @ 3.05 g/t Au and 17.1 m @ 5.47 g/t Au (multiple sub‑intervals up to 12.31 g/t Au)

  • PEP058 – 34.85 m @ 3.42 g/t Au (incl. 20.1 m @ 4.7 g/t Au)

  • Coarse Gold Verification – The two high‑grade samples from PEP055 were re‑assayed twice, confirming no significant sampling bias.

  • Program Status – Infill drilling is ahead of schedule; a mid‑program review may allow completion by late Oct 2025. Post‑completion, the rig will shift to either further Pepas work or exploration at the APTA prospect.

  • Metallurgical Testing – Planning underway for one‑ or two wider‑diameter (PQ) metallurgical holes; laboratory partners being engaged in South and North America.

  • El Cedro Soil Program

  • ~65 % complete; soils show extensive anomalous gold (>0.3 g/t Au, with zones >1 g/t Au).

  • Mapping indicates a complex gold porphyry system with associated vein structures and base‑metal mineralisation (assays pending).

  • Future Work – Upon completion of the soil program, data will be compiled to plan the next phase, potentially involving drilling at El Cedro.

  • Corporate Context – The Anzá Project is now 100 % owned by Orosur following a share purchase in Nov 2024. The company has drilled 48 holes post‑transaction with historic grades ranging up to ~12 g/t Au.

Notable Quotes

“The Anza Project continues to develop and broaden in scope. Pepas is progressing toward MRE as planned, but the results at El Cedro are showing this licence has much more to give.” – Brad George, CEO, Orosur Mining Inc.
