Aeris Resources Limited presented outstanding results of its drilling program in the Tritton Operation, located in central New South Wales.
The firm was producing high grade copper intersections at Avoca Tank and Budgerygar. Strike extension and depth continuity are supported by these results. The results will be used for future Mineral Resource updates, management said.
The results are a boost to confidence in near-mine growth potential. They also assist in better short-term production planning. The Tritton Operation continues to be a key copper operation for the Company.

New Mineralised Trend Extends Strike Beyond Expectations
A new mineralised trend was confirmed at Avoca Tank which was connected to the central mined corridor. The system now extends over 160 metres along strike.
This is more than the previously interpreted length of 2.15 metres. The most significant intersections are ATEL122 with 6.6m at 6.52% Cu. Other areas of good performance include ATEL154 at 24.0m, 3.03% Cu.
The creativity of this group was well demonstrated with several holes returning above 4% Cu. The mineralised system is open along strike and at depth. These results are being incorporated into geological modelling.

Deep Drilling Reveals Strong Grade Continuity Below Resource
High grade results are still being achieved for resource extension drilling below the current Mineral Resource. Intersections show uniform distribution of copper in the mineralised corridor. Significant assays are ATGC405 with 9.5m at 8.48% Cu.
The highlights also include ATGC374 which has 9.5m at 4.22% Cu. These results apply to the resource for depths up to 200 metres below that reported.
The continuity indicates possible additions to inventory that can be mined. Detailed interpretation continues in the deeper sections. New estimates will be made available in the next quarter.
Budgerygar Delivers Thick Intersections Supporting Upgrade Path
The Budgerygar deposit’s resource definition drill program was completed. Results show thicker sulphide zones than the previous modelling. The key intersections with BDEL121 are 39.5m (1.72%) Cu.
Other results include BDEL116 at 21.1m and 2.58% Cu. These results provide support for the current Inferred Mineral Resource to be upgraded to Indicated Mineral Resource.
As described, the lens consists of a stack of copper sulphide lenses, and three such lenses were drilled. A 250 metre down dip extent was the program length. New data will now be used in the development of the geological modelling.

Underground Strategy Targets Near-Mine Expansion
Aeris and Triton are advancing a focused underground drilling program aimed at strengthening near-mine growth and operational flexibility.
- Four drill rigs are currently operating underground at Tritton.
- The rigs are managed by Aeris to support expansion efforts.
- Drilling targets include Avoca Tank, Budgerygar, Triton, and South Wing.
- These deposits provide key short- to medium-term ore sources.
- Any new mineralisation would sit close to existing processing facilities.
- Proximity supports cost-effective development and infrastructure use.
- The strategy enhances mine scheduling flexibility and operational planning.
- Priority remains on resource definition and extension drilling.
- Additional drilling is scheduled through FY26 and into FY27.
- The program integrates exploration activities directly with mining operations.
Resource Updates Scheduled For Q4 FY26
Both deposits are expected to receive Mineral Resource updates in Q4 FY26. The drilling is progressing while Avoca Tank interpretation continues. The updated estimate will be updated as a result of Budgerygar results.
Management hopes for better conversions at Budgerygar lenses. The 007 and 008 sulphide bodies are the primary upgrading targets. There is continuing strong geological continuity in the system around Triton.
There is ongoing exploration drilling on the operation. The developments further strengthen the company’s organic growth pipeline. More updates to follow once modelling activities are complete.
Why These Results Matter For Investors And Operations
The latest drilling results strengthen Tritton’s long-term growth outlook and operational confidence. Key implications include:
- Enhanced Long-Term Copper Confidence: The new drilling reinforces the long-term copper potential of Tritton.
- Improved Geological Scale Understanding: Extended strike length supports stronger and more reliable geological models.
- Greater Production Stability: High-grade continuity helps underpin consistent and predictable production planning.
- Potential Resource Confidence Upgrade: Improved classification outcomes may increase overall resource reliability.
- Stronger Mine Design Parameters: The results could positively influence future mine planning and engineering decisions.
- Reinforced Underground Growth Strategy: The findings validate the importance of ongoing underground exploration drilling.
- Multiple Directional Expansion Potential: Mineralisation remains open in several directions, indicating further upside.
- Proven Exploration Effectiveness: The company’s structured scientific approach continues to deliver tangible results.
