Austral Gold Limited Reports Surface Silver-Gold Results At Juncal
Austral Gold Limited completed Phase 1 of its exploration program at its 100%-owned Juncal Silver-Gold Project in Chile. Phase 1 comprised geological mapping and more than 1,000 metres of channel sampling in trenches using a diamond-blade rock saw. Significant silver-gold results from channel sampling, with continuous surface mineralisation identified across seven of eleven mapped veins. Javiera vein: approximately 1,400 metres of strike; length-weighted average grade of 183 g/t AgEq over 0.7 metres (25 channels) for 128 g/t·m AgEq. Sofia vein: approximately 500 metres of strike; length-weighted average grade of 68 g/t AgEq over 1.8 metres (15 channels) for 122 g/t·m AgEq. Koda vein: approximately 500 metres of strike; length-weighted average grade of 71 g/t AgEq over 1.8 metres (7 channels) for 128 g/t·m AgEq. Channel sampling identified continuous surface mineralisation along strike across seven of the eleven mapped veins, confirming grades identified during reconnaissance and refining the structural interpretation. Selected intervals (reported at a 30 g/t AgEq cut-off) are shown in Table 1. Samples are analysed at the internal laboratory of Austral's Chilean subsidiary, Guanaco Compañía Minera SpA. The Company maintains a QA-QC program across all processes involving geological samples, including the insertion of standards and blanks, analytical and field duplicates, and a representative subset of pulps submitted to accredited external laboratories for independent verification. NW-trend System: interpreted as the dominant and oldest structural corridor within the district; i.e. Gloria Vein. NE-trend System: interpreted as a secondary system that appears to offset the Gloria system through dextral displacement; i.e., Barreales, Romané, Sofia, Carolina, Mia and Isidora veins. ENE-trend System: interpreted as a smaller conjugate structure associated with a later-stage deformation event. i.e.: Javiera, Koda and Edith veins. The intersection of the Gloria and Romané systems in the northwestern sector coincides with a broad zone of hydrothermal alteration and is interpreted as a priority target due to its potential to focus hydrothermal fluid flow and mineral deposition. Tourmaline breccia bodies identified in the eastern portion of the Project, predominantly affecting intrusive units, may represent an additional component of the district's hydrothermal evolution. Building on the Phase 1 results, the Company is advancing the next stages of its exploration program. Phase 2: June-August 2026. An induced polarisation (IP) survey is planned, building on the Phase 1 drone-supported magnetic survey, to refine drill targets. The survey will focus on structures associated with identified geochemical anomalies in the silver-gold (Ag-Au) veins. Phase 3: September-November 2026. Approximately 10,000 metres of reverse circulation (RC) drilling is planned, using Company-owned equipment and operated by DV Drilling contractor company. Drilling is designed to test down-dip extensions of mapped structures and assess potential mineralisation below the surface, including areas not exposed at the surface. As no historical or modern drilling has been undertaken at Juncal, this program will represent the first systematic test of subsurface continuity of the mineralisation.

Widths are channel (sample) lengths, not necessarily true widths; true widths are interpreted to be lower. AgEq = silver equivalent. Results reported in accordance with JORC 2012 and NI 43-101. Silver equivalent (AgEq) is calculated as: AgEq (g/t) = Ag (g/t) + [Au (g/t) × (Au price ÷ Ag price)]. AgEq assumes Austral Gold long-term metal prices of USD 27.5/oz silver and USD 2,500/oz gold (a gold-to-silver ratio of approximately 90.9:1). Metallurgical recoveries are assumed equal for all metals, as no metallurgical test work has been completed; recovery assumptions are therefore preliminary and may not be realised. It is the Company's opinion that all elements included in the metal equivalent calculation have a reasonable potential to be recovered. Widths quoted in the highlights (e.g. 0.4-1.5 metres for Javiera) are the mineralised channel widths used to calculate the reported length-weighted average grades.
