GoldArc Resources Ltd (ASX:GA8) Several New Unexplored Gold Targets Identified at Leonora North Project

27 October 2025

Price Sensitive Announcement $

Highlights:

• Five main gold anomalies, including 3 significant new targets (S3, S4, S5) identified from extensive 902 soils samples survey at Leonora North Gold Project.
• New, high-priority S4 anomaly defined, measuring 1.2km long by ~0.5km wide.
• Geochemical analysis (probability plot) indicates S4 is stronger in grade than the anomaly over the existing Mt Stirling gold deposit.
• S4 is associated with favourable geology, including outcropping gabbro, basalt, and south-west oriented quartz veining.
• Two further new anomalies, S3 (1.1km) and S5 (0.5km), also identified; all three new anomalies have never been drill-tested.
• S1 (2.5km) and S2 (1.5km) anomalies confirm strong potential to extend known mineralisation at the Mt Stirling, Hydra, and Tyrannus prospects.
• Systematic follow-up including infill soils, rock chipping, and aircore drilling is now being planned.

Overview:

GoldArc Resources Limited (ASX:GA8) has reported highly encouraging results from a 902-sample soil survey at its Leonora North Gold project. The program has successfully identified five main gold anomalies, including three significant new targets (S3, S4, and S5) that have never been drill-tested.

Soil Survey

During the year 2025, 902 soil samples (including duplicates, blanks and standards) were collected in three phases in the northern part of the Leonora North Project. Multiple gold anomalies were identified. Two anomalies S1 and S2 are clearly associated with gold deposit
at Mt Stirling and mineralisation at Hydra and Tyrannus prospects and they indicate that there is additional gold potential to increase the resources along the soil anomalies that have not
been drill-tested.

The newly defined S4 anomaly is considered the highest priority target from the program. It is a large, cohesive anomaly measuring 1.2km long and 0.5km wide.

Significantly, the anomaly coincides with favourable geological indicators, including outcropping gabbro and basalt, and south-west oriented quartz veining, which is a promising sign for mineralisation. Interestingly, both S3 and S4 are intersected in the middle by
Wonambi Fault.

In addition to S4, the survey identified two other new, untested targets (Figure 1):

• S3 Anomaly: a 1.1km long anomaly with a southwest orientation.
• S5 Anomaly: A 0.5km long anomaly with a northwest orientation.

  None of the S3, S4 or S5 anomalies have ever been drill-tested, representing compelling
  ‘walk-up’ targets for a new gold discovery.

The survey also reinforced the potential to grow the Company’s existing resources at Leonora
North.

• S1 Anomaly: This 2.5km long anomaly is associated with the existing Mt Stirling gold
  deposit and the Hydra prospect along the Hydra Fault. It highlights clear potential mineralisation between these two prospects.
• S2 Anomaly: This 1.5km long anomaly coincides with the Tyrannus prospect along
  the Wanambi and Ursus Faults, indicating potential to expand mineralisation in this area.

Next Steps

The Company is planning a systematic follow-up program focused on advancing these new anomalies toward drill-ready status. This work will include infill soil sampling, geological mapping, and rock chip sampling, prior to a planned AC drilling program.

Drilling will also be planned to test the strike extensions of the S1 and S2 anomalies, targeting extensions to the known mineralisation at Mt Stirling, Hydra, and Tyrannus

Company Notes:

GoldArc Resources Managing Director, Paul Stephen commented: “These results are outstanding and a testament to our systematic exploration approach. To define three brandnew, undrilled anomalies is a great outcome, but the quality of the S4 target is exceptional.

Geochemical data suggests S4 has the potential to be a larger and higher-grade system than the one we’ve already defined at Mt Stirling. This full validates our belief in the untapped discovery potential at the Leonora North, and we have now generated a pipeline of high-priority targets for immediate follow-up and drilling.”
