Corporate and Operations Update

• Great Plains Metals Corp. completed four diamond drill holes totaling 500 meters at the Everton Project in Victoria, Australia.
• Visible molybdenite was observed in all four holes, along with unidirectional solidification textures (USTs) indicating pencil porphyry systems.
• One additional hole is planned for completion by end of April 2026; assay results expected in Q2 2026.
• Shallow air core drilling commenced at the Yeoval Goodrich site to test for porphyry-related cupolas under alluvial cover.
• Management change: Peeyush Varshney appointed as new CEO, succeeding Aidan Bishop who remains on the Board of Directors.
• Corporate updates include engagement of Pretium Communications Inc. for marketing services at $2,500/month and a new website launch.

• The completion of drilling and visual confirmation of molybdenite validates the geological model established in previous announcements (March 2026).
• While positive, this is an incremental update on a previously announced program rather than a discovery of a resource or assay result that would fundamentally alter valuation.
• The CEO transition from Aidan Bishop to Peeyush Varshney provides continuity as the former remains on the Board; this mitigates risk but does not constitute a "Game Changer" without external validation of the new CEO's track record.
• The news is in line with previous expectations regarding drilling timelines and assay release schedules (Q2 2026).
• No immediate dilution or financing event is announced, preserving capital structure stability for now.

• Great Plains Metals Corp. focuses on exploration in Tier-1 jurisdictions (Australia).
• Flagship Project: Everton Molybdenum Project (Victoria), a past-producing mine (~20,000t @ 1.4% Mo mined historically between 1918-1926).
• Secondary Projects: Yeoval Goodrich (NSW) targeting copper-gold porphyry systems; Mt Rose discovery nearby.
• Strategy: Delineating geometry and size of pencil porphyry systems identified via legacy data re-evaluation and geological mapping.
