HIGHLIGHTS
➢ Side Well Gold Project Mineral Resource Estimate update (MRE) updated:
o 16.0Mt @ 2.0g/t Au for 1.02 million ounces of contained gold
➢ This establishes Side Well with a substantial resource inventory in a project with
district-scale, multi-kilometre potential
➢ Well-defined, high-grade gold ounces within a robust geological model
➢ 61% of ounces in the higher confidence Indicated category and circa 90% of ounces are considered to have potential for open pit mining
➢ Significant recent drilling intersections including 105m @ 2.41g/t Au at Eaglehawk and the recent intersection of deep visible gold mineralisation below Mulga Bill indicate
enormous upside to this Mineral Resource Estimate, providing increased confidence in
the multi-million-ounce potential of Side Well.
➢ Mulga Bill deposit grows to 642,000oz @ 2.4g/t Au (77% Indicated), with a very high-grade component of 441,000oz @ 5.3g/t
➢ 2025 has been a very successful year with resource growth at Mulga Bill and Ironbark bolstered by four new deposits with maiden MREs: Eaglehawk, Flagpole, Saltbush and Golden Bracelet, all of which offer significant potential for further growth
➢ With at least 3 rigs recommencing drilling in January 2026 and a strong cash balance, Great Boulder will be working to rapidly grow its resource inventory and progress Side Well towards production.

Great Boulder’s Managing Director, Andrew Paterson commented:
“This is a significant milestone for Great Boulder and for the Side Well Gold Project.
“When we first started drilling at Side Well, we quickly realised the project had genuine multi-million-ounce potential and we are very pleased to deliver on the first 1Moz milestone as we continue to aggressively drill and deliver further resource growth and additional discoveries.”
“Recent results have highlighted immediate upside to the resource; for example the recent visuals from deep holes (200m below previous drilling) at Mulga Bill highlight the enormous potential of that system.
“Meanwhile we’ve only completed a small amount of drilling at Flagpole and Golden Bracelet, both of which remain open along strike and at depth, and Eaglehawk is only just emerging.
“Our systematic exploration highlights the massive potential for the Side Well project, indicating strong resource growth into 2026 and beyond.
“With multiple rigs growing the resource base we also remain focused on our development path. The Company intends to lodge mining lease applications covering Mulga Bill, Eaglehawk and Saltbush in the New Year while we continue moving the project towards production.”
