Trigg Minerals has defined an Exploration Target at Antimony Canyon of approximately 12.8 to 15.6 million tonnes at grades ranging from 0.75% to 1.5% antimony (Sb), representing between 96,000 and 234,000 tonnes of contained antimony metal. This target is conceptual in nature and reported in accordance with the JORC Code (2012), with further exploration required to determine whether a Mineral Resource can be estimated.

The target is based on a footprint measuring 4.31 km by 2.42 km and an average mineralised thickness of 3 metres, indicating a potential mineralised volume of 5.6 to 6.8 million cubic metres. Mineralisation is stratabound within flat-lying calcareous sandstone units of the Flagstaff Formation and demonstrates strong lateral continuity, supported by over 30 historical mines and adits throughout the project area.

The model draws from validated historical sampling by the USBM and USGS and applies conservative parameters, including a density of 2.3 t/m³ and 3m thickness. Any increase to these assumptions following current exploration could significantly enhance the tonnage and metal content.

Technical reporting is being undertaken by Dahrouge Geological Consulting Ltd to meet both SEC S-K 1300 and JORC (2012) standards. Additionally, KLM Geoscience will commence a CSAMT geophysical survey over key areas from 14 July 2025. Historical data sources (Travers, 1949; Duncan & Myers, 1949) have been verified as reliable for grade and distribution.

The Company also confirms that all funds from the Placement announced on 2 July 2025 were settled on schedule by 8 July 2025, with shares to be issued on 14 July 2025. The total amount raised remains unchanged.
