• 75% of 15,000m Phase 1 diamond drill program at Burbanks Project completed
• Recent assays have returned continued high grade hits including 2.00m @ 235.70g/t Au
• Two metallurgical holes completed to support mine feed planning for the Black Swan Processing Hub

Horizon Minerals Limited has provided an update on the ongoing drilling program at its 100% owned high-grade Burbanks gold project, located 9km south of Coolgardie in the Western Australian Goldfields. The Phase 1 diamond drill program, comprising 15,000m, is now 75% complete, with recent assays continuing to return exceptional high-grade gold mineralization. Highlights include: 2.00m @ 235.70g/t Au from 248.31m, including 1.16m @ 396.62g/t Au; 0.32m @ 5.14g/t Au; 0.52m @ 5.25g/t Au; 2.00m @ 3.16g/t Au; 1.00m @ 6.29g/t Au; 4.50m @ 2.55g/t Au; and 1.00m @ 6.24g/t Au. The drilling has targeted multiple zones, including the gap between the Main Lode and Burbanks North resources, the area south of the Main Lode workings, and the Burbanks North resource. In addition, two metallurgical holes have been completed to support mine feed planning for the Company's 100% owned Black Swan Processing Hub. The remaining 15 holes from the Phase 1 program are expected to be reported by the end of the March 2026 quarter, enabling an updated Mineral Resource Estimate in the June 2026 quarter, followed by Ore Reserve studies.

The Company will continue the Phase 1 drilling program at Burbanks to complete the 15,000m campaign, with results expected through to the March 2026 quarter. This will be followed by a 15,000m Phase 2 extensional drilling program aimed at growing the resource base, commencing in the first half of 2026.
