Far East Gold (ASX:FEG) high grade mapping broadens Idenburg’s mineralised footprint

Far East Gold has reported further advances at its flagship Idenburg Project in Indonesia, where detailed geological mapping across the North Bermol, South Bermol and Nova prospects has identified new zones of quartz sulphide veining within low angle shear and thrust faults.

The results affirm that gold mineralisation of the same structural style extends across multiple prospects within the broader Idenburg area.

Highlights

• North Bermol grab and outcrop assays up to 22.1 g/t gold and 11.8 g/t silver.

• South Bermol grab and outcrop assays up to 7.1 g/t gold and 2.6 g/t silver.

• Nova grab and outcrop assays up to 8.1 g/t gold and 2.1 g/t silver.

• Mapping confirms low angle shear related mineralisation at several prospects.

• Two drill rigs currently operating at North Bermol and Sua.

The current surface program runs in parallel with Phase 1 drilling and builds on a review of historical work compiled by SMGC.

Field teams have mapped sulphide bearing quartz veins in interpreted low angle structures, a mineralisation style that drilling has already confirmed at Bermol and North Bermol.

The Bermol district is interpreted to follow a structural corridor of about four kilometres, and recent work shows that northwest trending shear zones host high grade veins within this corridor.

At Nova, roughly four kilometres north of Sua, initial mapping has outlined mineralised quartz sulphide veins within low angle shears that mirror the Bermol setting.

Historical work reported by SMGC delineated a 300 metre cluster of anomalous soil gold above 0.1 g/t, while outcrop sampling returned one metre at 3.90 g/t gold and one metre at 9.06 g/t gold.

Recent company sampling at Nova produced grab results up to 8.12 g/t gold, corroborating the earlier dataset and pointing to multiple mineralised positions within the prospect.

“These results confirm that similar gold mineralised fault and shear structures occur within multiple prospects, underscoring the strong potential for additional gold discoveries through continued drill testing of defined targets.”

The geological context is consistent with orogenic lode gold. Prospects sit within the Idenburg Inlier, a terrane of metamorphic rocks with dismembered ophiolites emplaced along regional thrust faults.

Company descriptions cite fluid inclusion and petrographic work that align with auriferous sheared quartz veins in metamorphic hosts.

Processing characteristics from earlier test work are supportive, with preliminary results from the Sua district indicating gravity recoveries of around 50 to 60 percent and overall recoveries above 95 percent using conventional leach flowsheets.

Preliminary work on Bermol material suggested minimum gold recoveries by carbon in leach exceeding 80 percent.

The company confirms that the Idenburg Inferred Mineral Resource reported under the 2012 JORC Code remains unchanged, and that the underlying assumptions and technical parameters continue to apply.

This resource position provides context for the current campaign that aims to convert new surface targets into drill supported zones.

With two rigs active and detailed mapping continuing, Far East Gold is methodically extending the mineralised footprint at Idenburg while testing priority targets derived from the emerging structural model.

The confirmation of similar low angle shear hosted mineralisation at multiple prospects, including Nova, strengthens the district scale interpretation.

As results are integrated from surface and drilling programs, the focus turns to delineating continuity and geometry of the newly mapped zones within one of Indonesia’s prospective orogenic gold settings.
