Portfolio and growth strategy

• South Cobar strategy targets systematic exploration across a mature mining belt; the Achilles discovery supports the district-scale opportunity.

• Two 2025 acquisitions for $1.9 million established a consolidated South Cobar land position, including the 6.5 km Browns-Evergreen system and ~25 km of historic drilling.

• Growth plan includes Achilles resource extensions, an initial Evergreen resource, and gold-focused exploration at Junee.

Achilles silver-gold deposit

• Initial JORC resource totals 10.3Mt at 116g/t AgEq for 38.5Moz; Indicated resources are 5.0Mt at 141g/t for 22.5Moz and Inferred resources are 5.3Mt at 93g/t for 16.0Moz.

• 58% of AgEq ounces are Indicated; resource comprises 28.7Moz open-pit and 9.8Moz underground resources.

• Mineralisation extends from surface to over 540m down dip; drilling includes 6m at 2,474g/t AgEq from 212.65m, outside the December 2025 MRE.

• Further drilling targets a near-term resource upgrade, including extensions at depth; the deposit remains open.

Browns-Evergreen

• Evergreen drilling expanded the mineralised zone from a previously identified 150m width to over 500m; multiple holes had assays pending.

• Highlight intercept: 17m at 5.3g/t Au, 163g/t Ag, 0.8% Cu and 17.3% Pb+Zn from 128m, including 8m at 10.4g/t Au and 29.0% Pb+Zn.

• Drilling is intended to support an initial JORC-compliant resource; an 8,000m DD/RC program was underway.
