Aton Reports Final Results from The Abu Marawat Diamond Drill Programme, Including 39.55 G/T Gold And 161 G/T Silver Over 3.90 Metres from The JVZ Structure, And 9.63 G/T Gold And 86.5 G/T Silver Over 17.70 Metres from the CVZ

Executive Summary

• Aton Resources released final assay results from the last 19 diamond drill holes (AMD‑196 to AMD‑213) and a re‑entry of hole AMD‑102 at the Abu Marawat deposit in Egypt, revealing multiple high‑grade polymetallic intersections.
• Notable intercepts include 39.55 g/t Au & 161 g/t Ag over 3.90 m (JVZ structure), 9.63 g/t Au & 86.5 g/t Ag over 17.70 m (CVZ), and several >5 g/t Au intervals with significant Cu/Zn grades, underscoring the deposit’s potential for a combined gold‑silver‑copper‑zinc operation.
• The company announced ongoing metallurgical testing, RC drilling, environmental baseline work, and progress on expanding the Hamama West Pre‑Feasibility Study to incorporate Abu Marawat and Semna deposits.

• Program Completion: Total of 113 diamond holes drilled, 9,642.7 m total depth; final tranche focused on high‑grade targets and metallurgical core collection.

• Operational Updates:

• Ongoing discussions with Egyptian authorities (MRMIA & MoP) to incorporate Abu Marawat and Semna into the Hamama West Pre‑Feasibility Study, shifting from heap leach to modular CIL processing.
• SLR engaged for comprehensive metallurgical testwork (head assays, comminution, leaching, flotation/SART). Samples delivered July 2025; program on schedule.
• ~5,000 m RC drilling commenced late July 2025, expected completion Oct 2025; results to be released in coming weeks.
• Additional diamond drilling at Hamama for metallurgical and geotechnical purposes; 115 core samples sent to Fugro SAE for pit‑wall stability testing.
• Environmental baseline work progressing: concession‑wide biodiversity survey completed; ESIA baseline monitoring ongoing.

Notable Quotes

• “This is yet another series of exceedingly positive drill results from the Abu Marawat deposit, in our retained exploration areas,” said Tonno Vahk, CEO. “We continue to push ahead on metallurgical and geotechnical diamond drilling… and look forward to positively concluding discussions with Egyptian authorities.”

Materiality Assessment: Material – Positive (the high‑grade intersections materially enhance the economic outlook for Abu Marawat and support advancement of the pre‑feasibility study).
