Far East Gold Ltd has reported further high-grade gold intersections from drilling at the Sua prospect within its Idenburg Gold Project in Papua, Indonesia, extending the known mineralised system and paving the way for an updated mineral resource estimate.

The areas of announced PIPPIB forest reclassification are also indicated. Refer to Appendix 1 Table 1 for details of the JORC2012 Inferred Mineral Resource Estimate forIdenburg as completed by SMGC. Coordinates are referenced to datum WGS84, zone 54 south.
Assay results from drillholes KSD028 to KSD035 confirm that shear-zone-hosted gold mineralisation extends about 100 metres down-dip and along strike to the northeast. The mineralised zones remain open both at depth and along strike, highlighting the potential for additional resource growth as drilling continues.
The company has engaged SMG Consultants Ltd to update the current JORC 2012 Inferred mineral resource estimate for the Idenburg project, which currently stands at 540,000 ounces of gold at 4.1 g/t. The upcoming update will incorporate results from Far East Gold’s recent drilling at the Sua prospect.

At the same time, the company is preparing the next phase of drilling at Sua, targeting further resource expansion. The planned program is expected to include about 2,350 metres of targeted drilling, with further details to be announced shortly.
High-grade intercepts confirm continuity
Recent drilling has delivered several notable gold intercepts that extend the mineralised system and confirm continuity within the shear-hosted structure.
Key intersections from the latest drilling include:
▶︎10.29 g/t gold over 1.65 metres from 17.1 metres in hole KSD033
▶︎2.12 g/t gold over 8.6 metres in KSD033, including 8.55 g/t over 1 metre
▶︎2.57 g/t gold over 3.9 metres in KSD034, including 7.92 g/t over 1 metre
▶︎5.24 g/t gold over 1.45 metres in KSD035, including 7.21 g/t over 0.95 metres
▶︎1.18 g/t gold over 7.4 metres in KSD035, including 4.97 g/t over 0.6 metres
“The high-grade intercepts in KSD033 to KSD035 extend the previously reported mineralisation to deeper levels and further confirm the strength and continuity of the Sua shear-hosted gold system,” Far East Gold non-executive chairman Justin Werner said.
“Importantly, the mineralisation remains open down dip and along strike to the northeast, highlighting strong potential for additional resource growth through continued drilling.”

Expanding the Sua gold system
Step-out drilling across the Sua prospect has progressively extended the mineralised system along both strike and depth.
Recent holes have tested both the eastern and western extents of the shear zones and confirmed continuity across the structure. Holes KSD028 and KSD029 advanced drilling east of earlier holes to further test the extent of mineralisation within the shear zones.
Hole KSD030 confirmed down-dip continuity in the central zone, intersecting 8 g/t gold over 0.5 metres within a broader 32-metre mineralised shear zone, highlighting the potential scale of the system.
Western step-out holes KSD031 and KSD032 also intersected multiple mineralised zones, reinforcing strike continuity across the prospect area.
To date, Far East Gold has completed 14 diamond drillholes at the Sua prospect for a total of 2,925 metres, targeting extensions to previously identified mineralisation. Assays for one remaining hole, KSD036, are still pending.

From KSD033 significant assay interval of 8.55 g/t Au over 1.0m from 97.2 to 98.2m, C) Deformed and chloritized metadiorite with overprint of coarse pyrite. From KSD035 significant assay interval of 7.21 g/t Au over 0.95m from 142.75 to 143.7m.
Large shear corridor offers further upside
Mineralisation at Sua is hosted within a series of stacked milky quartz veins with sulphide mineralisation developed within low-angle shear zones. More than 30 individual gold-bearing quartz veins have been identified to date.
The prospect sits within the 5-kilometre-long Sua–Afley shear zone, a major structural corridor that the company believes offers significant potential for additional high-grade discoveries.
Based on historical exploration and earlier drilling, the Sua prospect currently hosts an inferred resource of 2.5 million tonnes at an average grade of 3.7 g/t gold for approximately 296,000 ounces.
Recent drilling has focused on testing extensions beneath existing mineralisation, with results suggesting higher-grade gold zones may occur deeper within the shear system beneath lower-grade material encountered closer to surface.
Future drilling will continue targeting extensions to these zones down-dip and along strike to the northeast. Meanwhile, ongoing surface mapping at the nearby Kwaplu prospect is expected to help define targets for an initial scout drilling program.
The latest drilling results and the upcoming resource update are expected to provide a clearer picture of the scale and growth potential of the gold system emerging at Idenburg.
