Highlights
- FEG has reported promising assay results from its first drill hole, KSD023, at the Sua Prospect in Indonesia.
- The Idenburg Gold Project hosts an inferred JORC (2012) resource of 540,000 ounces of gold at an average grade of 4.1 g/t Au.
- In hole KSD023, coarse visible gold was reported.
- The hole confirmed and validated results from historical hole KSD002, which previously intersected 11 g/t Au over 11m.
- Metallurgical tests indicate 50–60% gravity recovery and over 90% total gold recovery through CIL or RIL processes.
- The company is also mapping and sampling the nearby Kwaplu Prospect.
Far East Gold Limited (ASX:FEG) has reported encouraging results from its first drill hole, KSD023, at the Sua Prospect within the Idenburg Gold Project in Indonesia. The project currently hosts a JORC (2012) inferred mineral resource of approximately 540,000 ounces of gold (Au) at an average grade of 4.1 g/t Au, including an estimated 296,000 ounces at an average grade of 3.7 g/t Au.
In KSD023, coarse visible gold was reported within a near-surface quartz vein, returning an assay of 82 g/t Au over 0.4m. This interval is part of a broader 9.8m zone grading 13.77 g/t Au from a depth of 18.5m. The hole was designed to twin historical hole KSD002, which previously returned 11 g/t Au over 11m from 18m depth, including 52.5 g/t Au over 1.6m.
Key Highlights from Drill Hole KSD023
- 131 g/t Au over 0.8m (24.5m – 25.3m)
- 180 g/t Au over 0.4m (24.9m – 25.3m)
- 24.08 g/t Au over 5.3m (20m – 25.3m)
- 13.77 g/t Au over 9.8m (18.5m – 28.3m)
Additional findings include the observation of coarse visible gold within multiple quartz-sulphide veins. The assays from KSD023 confirm historical drill data and geological interpretations.
Significance of the Sua Vein System
The company considers this confirmation of high-grade, visible gold as a key step in realising the full potential of the Idenburg Project. The presence of coarse gold boosts the potential for developing a viable resource.
The goal of the planned Sua drill program is to map the extent of the vein system and assess the continuity of its internal zones.
Current Drilling Program
The ongoing Sua drill program aims to confirm geological interpretations, validate historical results and extend the current resource base. A total of 10 diamond drill holes, covering approximately 1,820m, are planned. These holes will test the continuity of mineralised zones at closer 50-meter spacing, compared to historical 100-meter intervals.
Metallurgical and Resource Details
Preliminary metallurgical testing on surface and drill core samples indicated that 50–60% gold was recoverable through gravity methods, with total recoveries exceeding 90% using CIL or RIL processes.
Kwaplu Extension and Future Work
The company is also conducting detailed mapping and sampling at the Kwaplu Prospect. Historical data from Kwaplu show quartz-sulphide veins with assay results exceeding 100 g/t Au. This area has not yet been drilled.
The company believes that the Sua shear zones may extend into Kwaplu. The mapping program at Kwaplu will provide additional drill targets following completion of the current Sua program.
