Fosters sits within ground already covered by Vertex Mining Licenses and existing Development Consent. Fosters is accessed by an existing Adit and development drive. For further information please refer to ASX Announcement “Exploration Target Calculated for Fosters” (29 August 2023). The Exploration Target is conceptual in nature as there has been insufficient exploration to define a Mineral Resource. It is uncertain if further exploration will result in the determination of a Mineral Resource under the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, the JORC Code” (JORC 2012). The Exploration Target is not being reported as part of any Mineral Resource or Ore Reserve.

Refer to VTX ASX announcement 5 July 2023 Reward Gold Mine Mine Ready for Production Experienced Team & Equipment High-Grade Stopes Gold ore is ready to mine at the Reward Gold Mine, with multiple headings available for advancement. Production of underground ore is scheduled to commence in September 2025. Advanced underground mining equipment is already on site or nearby, supported by a highly skilled mining team operating under the Vertex owner-operator model — where Grade is KING. One of he first stope block comprises 700 tonnes @ 42.5 g/t Au, with the total stope containing 2,075 tonnes @ 17.8 g/t Au, positioning the mine for strong early-grade production.
