Highlights

- Stelar Metals has successfully completed Phase 1 of its field program at the Hill of Leaders Tungsten Project

- Rock chip and grab samples collected across the Hill of Leaders tungsten field have been dispatched to laboratory for assay

- Program covered historic tungsten workings across the 2km+ mineralised corridor

- Field update to be reported shortly with first assay results anticipated in late June 2026

- Phase 1 Reverse Circulation (RC) drill planning remains on track to commence in July 2026

- Previous rock chip sampling at Hill of Leaders returned exceptional surface grades including 6.1% WO3, 2.1% WO3 and 1.45% WO3

Stephen Biggins, Executive Chair, Stelar Metals Limited commented:

"We are extremely pleased with the outcome of our first field program at Hill of Leaders. Our geological team systematically assessed the historic tungsten workings. With samples now on the way to the laboratory, we are building momentum towards our first tungsten drill program.

"The coming weeks will be very exciting for Stelar shareholders as we announce our initial field report, receive the first assay results, and commence Phase 2 on the ground."

Hill of Leaders Phase 1 Field Program

The program was conducted by Stelar's geological team and has materially advanced the Company's geological understanding of the mineralised system and has identified compelling areas for follow up.

Phase 1 comprised geological mapping and surface sampling across the extent of the Hill of Leaders tungsten field. Field activities included:

- Geological mapping of the 2km+ mineralised corridor, covering the Hill of Leaders, Curtis, Doria, and North Curtis prospects

- Examination of accessible historic tungsten workings, including shallow trenches and shafts from 1950s-era mining activity

- Preliminary assessments of vein swarm geometry, alteration zones, and greisen distribution to refine structural controls on mineralisation

- UV lamp scanning for scheelite identification across prospective zones

- Collection of rock chip and grab samples from mineralised outcrops, vein exposures and historic workings

Rock chip and grab samples have been collected and dispatched to an accredited laboratory for multi-element assay, with tungsten (WO3) and copper as primary analytes. Results are anticipated late June 2026.

Previous rock chip sampling at Hill of Leaders had returned outstanding surface grades, with results including 6.1% WO3, 2.1% WO3 with 11.85% Cu, 1.45% WO3, and 1.27% WO3. The expanded field program is intended to test the continuity of the exceptional surface mineralisation recorded in historic sampling of the Hill of Leaders system.

An update report summarising the initial field observation will be published to the ASX in the coming weeks, providing a detailed overview of the key findings that will inform the Phase 1 RC drilling program.

Next Steps

- Imminent - Detailed field update report published to ASX

- Imminent - Phase 2 mapping and sampling program to commence

- June 2026 - Phase 1 assay results

- July 2026 (target) - Phase 1 RC drilling commences (~3,000m over 3 sections)

- Q3 2026 - Phase 1 Diamond Drilling (~1,000m) to follow up RC results

- Q4 2026 onwards - Phase 2 RC/Diamond Drilling and Resource Drilling

Hill of Leaders Tungsten Project Background

The Hill of Leaders Tungsten Project is located on exploration licence EL33232, covering 445km2 in the world-class Tennant Creek mining region of the Northern Territory, approximately 80km from Tennant Creek and well serviced by major road and rail infrastructure connecting to Darwin Port.

Stelar has entered into a binding earn-in agreement1 with private company F&H Brothers Metals Pty Ltd, where Stelar has the option to acquire 100% of the project within 12 months.

No bedrock drilling has ever been conducted beneath the mineralised surface vein swarms, representing a genuine first-mover discovery opportunity which Stelar is actively moving to test.
