Highlights: Drilling underway. XXIX has commenced its planned large-scale drill program at the Thierry Copper Project, focused on the near-surface K1 deposit. K1 drill program.

The planned 20,000-metre, two-phased program is designed to test grade, scale and continuity under XXIX's updated bulk-tonnage interpretation and support a future mineral resource update. First systematic drilling in decades. The program represents the first systematic, large-scale drilling on the Thierry property in over 40 years.

Ontario's largest primary copper resource. Thierry is 100%-owned, royalty-free, and pairs the near-surface K1 zone with the high-grade, past-producing K2 zone. Modern geological model.

XXIX has rebuilt and reinterpreted more than 210,000 metres of historical diamond-drilling data into a modern, validated geological database. Materially new K1 interpretation. Historically modelled as sub-parallel tabular veins, K1 is now interpreted by XXIX as a near-surface, disseminated bulk-tonnage copper-PGE system with mineralization open at depth.

Fully funded. XXIX holds over $19 million in cash and approximately $24 million in working capital. Toronto, Ontario--(Newsfile Corp. - July 20, 2026) - XXIX Metal Corp ‎.
