Montage Gold announces that its Petit Yao target has the potential to become a higher-grade satellite of scale

Executive Summary

• Montage Gold reports multiple high‑grade intercepts at the Petit Yao target (7 km from the Koné processing plant), confirming >1.1 km of strike continuity and mineralisation to a depth of only 150 m.
• Key intercepts include 6.0 m @ 7.26 g/t Au (incl. 1 m @ 13.84 g/t and 1 m @ 16.40 g/t) and 6.0 m @ 5.09 g/t Au (incl. 1 m @ 23.00 g/t).
• The company plans an additional 6,800 m of drilling (plus ~1,000 m of auger work) before year‑end to delineate a maiden starter resource at Petit Yao and update resources across several other deposits.

Key Details

• High‑grade intercepts reported
• Hole PYRC007: 6.0 m @ 7.26 g/t Au (incl. 1 m @ 13.84 g/t, 1 m @ 16.40 g/t) from 55 m.
• Hole PYRC017: 6.0 m @ 5.09 g/t Au (incl. 1 m @ 23.00 g/t) from 59 m.
• Hole PYRC0033A: 5.0 m @ 5.12 g/t Au from 43 m.

• Additional notable intercepts:

  • Hole PYRC021: 14.0 m @ 1.44 g/t Au (53 m).
  • Hole PYRC015: 13.0 m @ 1.50 g/t Au (67 m).
  • Hole PYRC023: 9.0 m @ 1.62 g/t Au (122 m) and 2.0 m @ 2.23 g/t Au (136 m).

• Drilling coverage to date (2025)

• Total metres drilled on Petit Yao: 4,068.5 m across 43 holes (including 2 DD holes, 41 RC holes).

• Overall program for 2025: 252.5 m DD + 1,860 m RC (initial) + 1,957 m follow‑up = 4,068 m YTD.

• Planned drilling before year‑end

• Additional 6,800 m of RC and DD drilling aimed at infill and step‑out to support a maiden starter resource estimate.

• ~1,000 m of auger drilling on a newly identified soil‑geochemical anomaly northeast of Petit Yao.

• Resource update expectations

• Maiden resource for Petit Yao to be released after completion of the current drill program.

• Concurrent updates anticipated for Gbongogo South, Koban North, ANV, Yeré North, Lokolo Main, Sena, Diouma North deposits and any new discoveries.

• Metallurgical testwork (preliminary) on 25 samples:

• Oxide material average recovery ≈ 98.7 %.
• Transition material average recovery ≈ 97.5 %.

• Fresh material average recovery ≈ 96.0 %.

• Quotes

• “We are very excited with the initial drill results received for the Petit Yao target, which suggests that it has the potential to be delineated into one of the highest‑grade deposits of scale at our Koné project.” – Silvia Bottero, EVP Exploration.

• Technical verification – Results reviewed and approved by Qualified Person Silvia Bottero (BSc, MSc, SACNASP).

Notable Quotes

“Given the importance of this discovery, we have swiftly modified our exploration programme to immediately increase drilling at the Petit Yao target, with the goal of delineating a maiden starter resource in the coming months.” – Silvia Bottero, EVP Exploration.
