Orosur Mining Inc Announces New mineralised zone discovered near Pepas

• Date: 2026-04-14
• Headline: Orosur Mining Inc Announces New mineralised zone discovered near Pepas
• Core Announcement: Discovery of a new mineralized zone approximately 100m west of the Pepas deposit at the Anz\u00e1 Project in Colombia.
• Drilling Highlights:
  • Hole PEP082: 26.4m @ 2.85g/t Au (including 7.70m @ 5.07g/t Au).
  • Hole PEP083: 14.45m @ 8.27g/t Au from surface (including 2.55m @ 42.7g/t Au).
• Operational Updates:
  • Drilling commenced at the APTA prospect (Hole MAP106, planned depth 400m).
  • Drone-mounted airborne magnetic survey started over southern project area (APTA and El Cedro).
  • El Cedro prospect undergoing mapping/sampling; potential drilling in H1 2026.
• Context: This follows the February 2026 Maiden Mineral Resource Estimate (MRE) which defined 201,000 oz Indicated resources at Pepas.

• Impact on Valuation: The news confirms continuity and expansion of the mineralized system surrounding the newly defined Pepas resource. While high-grade intercepts (PEP083 from surface) are attractive for open-pit economics, this is an incremental update following the major MRE milestone in February 2026.
• Expectation vs. Reality: The company announced in January 2026 that exploration would expand to test new targeting concepts. This news fulfills that commitment rather than surprising the market with a completely new discovery.
• Risk Mitigation: High-grade surface intercepts reduce potential strip ratios for future mining, which is positive for project economics. However, the resource remains small (approx. 200k oz Indicated) and requires further drilling to convert Inferred resources or expand the footprint significantly.
• Market Reaction Potential: Given the stock has corrected ~50% from January highs ($0.72) to March lows (~$0.30), this news may provide a floor for the share price, but it is unlikely to trigger a re-rating comparable to the initial MRE announcement unless subsequent drilling significantly increases resource tonnage.

• Company: Orosur Mining Inc. is a gold exploration and development company focused on Colombia and Argentina.
• Flagship Project: Anz\u00e1 Gold Project, Mid-Cauca gold belt, west of Medell\u00edn, Colombia (~330km\u00b2). 100% owned by Orosur following the acquisition of Minera Monte Aguila (formerly JV with Newmont/Agnico Eagle) in November 2024.
• Development Stage: Early-stage development/Exploration. Maiden MRE released February 2026 (201,000 oz Indicated). Currently advancing toward economic study and permitting.
• Other Assets: El Pantano Project (Argentina), 51% owned with option to earn 100%.
