Slide 4: Key Project Centres and Company Focus
Key Project Centres and Company Focus • Romano – targeting “major” gold discoveries in frontier terrain environments, with proven large scale gold endowments nearby (+6M ounces of gold) • Kalgoorlie – targeting near term gold production opportunities from multiple advanced projects with open ended r
Slide 5: Two Priority Growth Centres
Two Priority Growth Centres Romano – the next major discoveries are likely to continue in the frontier terrains (Hemi, Nova, Gruyere) • The Romano Project, North-Eastern WA Goldfields hosts early exploration targets, including: • Gruyere North ( 1km on strike from Gruyere +6M Oz mine)* • Bloodwood (
Slide 6: Romano Project
1. Romano Project • Immediately on strike of the Gruyere 6Moz gold mine • Huge position -800km2 land position across multiple poorly explored greenstone belts • Over 70km of prospective greenstone belts • Targeting large scale gold deposits in this frontier terrain • Mineralised prospects already id

Slide 8: Romano Project – Bloodwood Exploration
Romano Project – Bloodwood Exploration • Modelled shear hosted gold First pass soil sampling and shallow air-core drilling identified gold anomalism over 5km strike • Encouraging first drilling results • Single follow up Diamond Drilling returned encouraging result • Targeting large scale gold depos
Slide 9: Romano Project – Brahman Exploration
Romano Project – Brahman Exploration • Modelled intrusive unit – targeting a Gruyere intrusion hosted analogue • First pass shallow air-core drilling identified gold anomalism • Follow up RC and Diamond Drilling returned encouraging results over 2km strike • Targeting large scale gold deposits • Pro
Slide 10: Kalgoorlie - Three Advanced Gold Prospects
2. Kalgoorlie - Three Advanced Gold Prospects • Capricorn - Resource • Baden Powell - Resource • Rockland - Discovery 10
Slide 11: Capricorn
Capricorn • Mineralisation: Multiple Loads 2m – 4m thick • Opportunity: Not previously mined – discovery stage • Strike: +250m • Resource: 659,300t @ 1.2g/t (0.5g/t cut-off)* • Vertical limit of resource : 135m • Open: North, South and at depth • Access: Proximal to the Goldfields Highway • Nearby G
Slide 12: Capricorn Cross Section
Capricorn Cross Section • Mineralisation across the Kalgoorlie suite remains open at depth • Regional surface depletion down to approximately 30m, as shown in this cross section of the Capricorn project • Assets recently discovered and not previously mined or minimal production • Primary gold minera
Slide 13: Baden-Powell
Baden-Powell • Mineralisation: Sub vertical loads • Resource: 595,300t @ 1.2g/t (0.5g/t cut-off)* • Vertical Limit: Majority of resource within 100m of surface • Open: North and South, and at depth • Access: <1km from Goldfields Highway • Milling: ~30km from Paddington and multiple other gold proces
Slide 14: Numerous Priority Exploration Targets
Numerous Priority Exploration Targets • Located south of Aphrodite (>1.3m Oz Au – Genesis Minerals), southern extension of prospective greenstone / basalt contact • Strong north-south soil & auger gold anomalies, many of which remain untested, ie. Olympia Prospect • Mostly shallow air-core / RAB (~5
Slide 15: Rockland – a New Discovery
Rockland – a New Discovery 1km Mineralised Gold Trend – barely tested • Gold mineralisation open at depth • Impressive gold grades (ASX 21/1/2025) from first-pass Dundas drilling including: • 6m @ 3.3g/t Au from 78m • 5m @ 2.3g/t Au from 109m • 2m @ 5.6g/t Au from 74m • Mineralisation extends north
Slide 16: Next Steps at Rockland
Next Steps at Rockland Drilling planned March 2026 • Rockland is emerging as part of a larger combined system with >1km Au trend at Rockland (granted M24/974) • Mineralisation open along strike and at depth • Down-dip potential across the ‘Rockland’ for maiden resource potential targeted • High-grad
Slide 17: Company Strategy
Company Strategy • Targeting district-scale discoveries in the frontier Romano (Yamarna region). • Consolidating shallow gold resources in the Kalgoorlie district. • The Kalgoorlie Projects are well positioned with supporting infrastructure and warrant further exploration and development studies • C
