CEO Commentary on Results

"Our latest assay results from the December quarter 2025 drilling program at Van Uden show strong gold mineralisation south of the historic Tasman pit. Thick intercepts of greater than 2.0 g/t Au persist at depth and will materially add ounces to the upcoming MRE update." – David Selfe, CEO

Strategic Focus on High-Grade Zeehan Area

The drilling campaign has particularly focused on the historically named Zeehan area south of the historic Tasman pit. Moreover, this area shows remarkable similarities to the high-grade Tasman pit but has seen no previous mining activity, representing a significant opportunity for resource expansion.

Zeehan Area Highlights:

• Multiple thick intercepts above 2.0 g/t Au at depth
• Mineralisation continues beyond 180 metres downhole depth
• Steepening gold mineralisation coincides with steepening basalt-sediments contact
• No previous mining activity in this high-potential zone
• Deepest hole (TGGR119) ended in mineralisation, indicating further depth potential

The deepest drillhole in this southern region intercepted 13m @ 2.23 g/t Au from 181m downhole. Importantly, this hole ended in mineralisation, suggesting significant depth extensions remain to be tested through follow-up drilling programmes.

Understanding Gold Grade: What Makes These Results Exceptional

Gold grade is measured in grams per tonne (g/t), representing the concentration of gold within the rock. However, the TG Metals drilling results at Van Uden can be assessed within industry standards:

TG Metals' intercepts averaging 1.6-2.5 g/t Au over substantial widths (13-30 metres) represent high-grade, thick mineralisation that is highly attractive for open-pit mining economics. For instance, the inclusion of bonanza-grade intervals like 12.39 g/t Au further enhances the economic potential.

Key Investment Metrics

• Current MRE: 227,140 ounces at 1.1 g/t Au
• Conceptual pit shell based on A$5,000/oz Au
• Multiple mineralisation zones showing depth continuity
• 5 RC drillholes with assays still pending

Comprehensive Drilling Programme Delivers Quality Data

TG Metals executed a systematic drilling approach using two truck-mounted rigs. The Schramm T660 provided deep drilling capability (>500m depth), whilst the Schramm X300 handled shallow to moderate depth drilling (~150m).

Technical Excellence

• 19 drillholes completed across entire Van Uden deposit length
• All holes drilled at -60° dip and 250° azimuth for optimal intersection
• 1-metre sampling intervals in mineralised zones
• PhotonAssay™ analysis providing high-quality results
• Quality control protocols with certified reference materials and blanks

The drilling targeted both infill areas to upgrade resource confidence and extension zones to expand the current resource boundary. Consequently, the drilling demonstrated particular success in proving continuity beyond the current conceptual pit shell.

Strategic Timeline and Upcoming Catalysts

TG Metals has outlined a clear timeline for advancing the Van Uden Gold Project toward development. The company has established specific priorities for each quarter ahead.

Immediate Priorities (Q1 2026)

• Complete pending assays for remaining 5 RC drillholes
• Diamond core drilling results expected in March 2026
• Commence updated MRE modelling upon completion of assays

Near-term Development (Q2 2026)

The company maintains adequate funding for planned activities. Additionally, diamond core drilling continues on-site to provide essential geotechnical data for mining studies.

Van Uden's Strategic Investment Advantages

The project benefits from its position in a world-class location within the Forrestania Greenstone Belt – a proven gold-producing region. Furthermore, it sits 90km from established infrastructure at Hyden with close proximity to Marvel Loch (producing) and Westonia-Edna May processing plants.

The deposit is also located 12.5km from Mt Holland lithium mine, placing it in an established mining district with proven infrastructure.

Resource Growth Trajectory

Geological Advantages

The project showcases multiple advantages including its orogenic gold system – a proven deposit type in Western Australia. The structural control along Van Uden Shear provides exploration targeting, whilst multiple mineralisation zones offer resource expansion potential.

Most significantly, fresh rock mineralisation averages 1.2 g/t Au over 2.5 million tonnes, providing a solid foundation for development studies.

What Are Orogenic Gold Systems?

Orogenic gold deposits form during mountain-building processes when gold-bearing fluids flow through fractures and shear zones in the Earth's crust. However, understanding these systems is crucial for appreciating Van Uden's potential.

These deposits are characterised by several key features:

• Structural control: Gold concentrates along fault systems and shear zones
• Depth continuity: Mineralisation often extends hundreds of metres below surface
• Multiple zones: Several parallel or intersecting mineralised structures
• Economic grades: Typically contain gold grades suitable for commercial mining

The Van Uden deposit exhibits classic orogenic characteristics. Moreover, gold mineralisation occurs within the Van Uden Shear, a major structural corridor that has channelled gold-bearing fluids through the rock sequence.

This geological setting suggests excellent potential for discovering additional mineralised zones both along strike and at depth.
