• Transition to high-grade underground gold production at Reward Gold Mine
• Established multiple mining fronts and completed key infrastructure upgrades
• Gravity-only processing plant achieves strong gold recoveries

Vertex Minerals Limited is pleased to present its Quarterly Activities Report for the quarter ended 30 September 2025. The quarter marked a pivotal milestone for the company, with the commencement of underground ore production at the Reward Gold Mine in Hill End, New South Wales. Following more than a year of planning, rehabilitation and infrastructure works, Vertex successfully re-entered the Reward workings and delivered the first high-grade ore from the Lady Belmore Reef in August 2025. This achievement represents the formal transition of Reward from development into production. During the quarter, Vertex established multiple production fronts across the Lady Belmore Reef and adjoining Mica veins, confirming both grade continuity and operational readiness. The first stope was fired in mid-August 2025, and subsequent firing and bogging operations during mid-to-late September 2025, particularly within the 1670 airleg and 1438 long hole stopes, confirmed the predicted vein geometry, grade continuity and ground conditions. By late September 2025, Vertex had completed the initial phase of underground production, establishing a consistent and reliable ore-to-plant supply chain. The Reward gravity-only processing plant operated continuously throughout the quarter, achieving metallurgical recoveries of 90+ percent. Several optimisation initiatives were implemented during the quarter to enhance reliability and throughput. The quarter positions Vertex as a new Australian gold producer with operational momentum, a clear pathway for production growth, and an experienced management team focused on responsible, profitable mining.

Vertex expects continuous expansion of underground development to increase gold output through Q4 2025.

Looking forward, the December quarter will see continued long hole stoping in the now developed mining fronts and the integration of additional ore sources to support steady-state production. With a clear development pathway, strong technical performance and a focused team on site, Vertex is positioned to generate sustained operational momentum through to 2026.
