Right Resources Reports 4.79 g/t Gold in Rock Chips at Aster Ahead of Drilling
Key Takeaways
- Rock-chip assays at Aster returned up to 4.79 g/t Au with 429 ppm bismuth, with five of 67 samples above 0.6 g/t Au.
- The first Aster aircore assays are due in November 2026, and they will show whether the surface gold signatures continue at depth.
- 51 aircore holes (22 at Aster, 29 at Luna) are complete as part of a roughly 60-hole, 2,000m first-stage program on EL9028.
- Aster is the highest-ranked gold target, sitting on a north-south shear corridor more than 4km long and about 800m across, though that is a structural dimension and not a mineralised body.
- The University of Tasmania's CODES will assess in the December Quarter 2026 whether the system is a single intrusion or multiple overlapping events, ahead of any RC or diamond drilling.
Aster gold results: rock-chip assays of up to 4.79 g/t Au sharpen Blue targets
Right Resources Limited (ASX: RRE) reported new rock-chip assays of up to 4.79 g/t Au at the Aster Prospect, alongside progress on Blue Project aircore drilling. The Blue Project sits approximately 22km north of Tumbarumba, New South Wales.
As at 11 October 2026, 51 aircore holes had been completed: 22 at Aster and 29 at Luna. Aster encompasses the eastern gold target from the 4 September 2026 announcement, which reported a peak rock-chip result of 5.16 g/t Au.
Graham Howard, Managing Director
“Our immediate objective is to determine whether the surface geological and geochemical signatures continue below surface and use the results to prioritise follow-up RC and diamond drilling.”
The practical takeaway is that surface results are now being tested at depth. Initial Aster assays are anticipated in November 2026, subject to laboratory turnaround times.

Four prospects define the Blue Project
Right Resources is now calling the broader exploration area the Blue Project and has named four prospects within it. The company says the names provide a framework for targeting and reporting exploration progress.
| Prospect | Focus | Ranking or status | Key feature |
|---|---|---|---|
| Aster | Gold-bismuth-tellurium targets | Highest-ranked gold target | North-south shear corridor extending more than 4km |
| Luna | Central tungsten-bismuth-gold targets | Priorities based on geological interpretation and logging | Includes the previously reported tungsten metallurgical sample area |
| Moonlight | Structurally controlled tungsten and gold target | Highest-ranked tungsten target | Structurally controlled target |
| Nova | Structurally controlled tungsten and gold target | Target for further mapping and proposed drilling | Structurally controlled target |
The company says these priorities will be refined as assay results become available. For investors, that means the rankings are a working view, not a settled one.
Aster gold data in detail
The announcement covers 67 new surface rock-chip samples from Aster, with gold assays ranging from below detection (<0.001 g/t Au) to 4.79 g/t Au. Eight samples returned more than 0.1 g/t Au, including five above 0.6 g/t Au.
Top results, with their bismuth (Bi) content, were:
- 4.79 g/t Au with 429 ppm Bi (RTRK_00491)
- 3.07 g/t Au with 167 ppm Bi (RTRK_00490)
- 1.525 g/t Au with 166 ppm Bi (RTRK_00493)
- 0.938 g/t Au with 66 ppm Bi (RTRK502)
- 0.626 g/t Au with 18.05 ppm Bi (RTRK_00497)
Gold-bearing samples are associated with quartz veins, pegmatite dykes and chlorite-altered shears. The company says the gold-bismuth association provides a vector for follow-up targeting within the interpreted intrusion-related system.
Mapping and geophysical interpretation indicate a north-south shear corridor extending more than 4km and approximately 800m across. These dimensions describe the structural corridor and do not represent a continuous mineralised body or true mineralisation width.
What are rock-chip samples and aircore drilling?
Rock-chip samples are selective surface samples. The company notes they may not represent average grade across the prospect, so they point to where to look rather than what is there.
Aircore is a shallow drilling method. This announcement reports surface rock-chip results and drilling progress only, with no drill assay results. The reconnaissance program is not designed to define a Mineral Resource, and geological logging and assay results will be used to prioritise potential follow-up reverse circulation (RC) and diamond drilling.
Drilling progress at Aster and Luna
The 51 holes form part of an approximately 60-hole, 2,000m first-stage program on EL9028, within a broader approximately 3,000m campaign. Further drilling on EL9889 is proposed, subject to approvals and refinement using first-stage results.
- Aster (22 holes): Testing selected portions of the north-south shear corridor along existing access tracks. Logging has identified pegmatites, aplites, quartz veining and shearing.
- Luna (29 holes): Drilling has focused on some priority targets identified through integrated geophysical interpretation and geological logging, and has tested the margins of the tungsten anomaly from existing access tracks.
The Luna metallurgical sample location has not been directly tested and requires approval to clear pine trees. Logging results are geological observations only, and gold grades remain subject to laboratory assays.

Next steps and catalysts
The company’s stated next steps include:
- Completing the first-stage aircore program and reporting assays as available, with initial Aster assays anticipated in November 2026
- Continuing geological mapping across Aster, Luna, Moonlight and Nova
- Extending soil and outcrop sampling across prospective areas of the Blue Project
- Progressing approval for pine-tree clearing and approvals for proposed further drilling on EL9889
- Ranking priority targets for potential follow-up RC and/or diamond drilling
The company will also work with the Centre for Ore Deposit and Earth Sciences (CODES), University of Tasmania, during the December Quarter 2026. CODES will assess whether the geology and geochemistry reflect a single intrusion-related system or multiple overlapping mineralising events, and the interpretation remains an exploration model requiring further technical work and drilling.
The nearest catalyst is the first Aster aircore assays in November 2026, which will show whether the surface signatures carry below the surface.
