Bindi Metals Quadruples High-Grade Gold Width at Drenjak to 8m at 13 g/t
Key Takeaways
- Final assays from RAV26011 have expanded the Drenjak high-grade intersection fourfold — from 2m @ 21.6 g/t Au to 8m @ 13.1 g/t Au, including a 2m interval grading 42.3 g/t Au from 47m depth.
- High-grade mineralisation is confirmed continuous from surface channel sampling (6m @ 15.3 g/t Au) through to approximately 100m down-dip, establishing a connected system rather than an isolated intercept.
- A second untested IP chargeability anomaly exceeding 60 mV/V sits immediately south of the drilled zone, giving the follow-up drill program a geophysically defined priority target.
- The maiden 14-hole, 2,159.4m diamond program also returned 5m @ 71.1 g/t Ag (including 1m @ 341 g/t Ag) and 16.4m @ 1.1% Ni at Rudnjak North, plus a new 800m x 300m gold-in-soil anomaly at the undrilled Bucje prospect.
- Ravni sits within the Kopaonik Metallogenic Zone, the same district hosting the approximately 8.6 Moz AuEq Rogozna deposit, providing meaningful geological context for the scale of the system being tested.
Final assays quadruple high-grade gold width at Drenjak
Final assays from hole RAV26011 have materially expanded the previously reported high-grade gold intersection at Drenjak, with Bindi Metals (ASX: BIM) confirming a broader 8m @ 13.1 g/t Au from 47m depth, including 3m @ 30.0 g/t Au and 2m @ 42.3 g/t Au. This replaces the previously reported interval of 2m @ 21.6 g/t Au and marks the completion of the company’s maiden 2,159.4m, 14-hole diamond drilling program at the Ravni Project in Serbia, with all assays now received.
The result confirms that high-grade gold mineralisation extends approximately 100m down-dip from surface channel sampling of 6m @ 15.3 g/t Au, including 2m @ 45.6 g/t Au. Crucially, mineralisation remains open and is associated with a strong >60 mV/V IP chargeability anomaly, while a second untested high-chargeability target has been identified immediately to the south.

What the Drenjak result means for investors
Breaking down the intersection
The full nested intersection hierarchy from RAV26011 is as follows:
- 8m @ 13.1 g/t Au, 0.2% Bi from 47m, including:
- 3m @ 30.0 g/t Au, 0.5% Bi from 47m, including:
- 2m @ 42.3 g/t Au, 0.7% Bi from 48m
- 2m @ 7.3 g/t Au from 51m
Gold mineralisation is hosted in diorite and volcanic breccia with bismuthinite-pyrite and pervasive silicification. Below the main zone, an additional interval of 4.1m @ 0.5 g/t Au, 2.6 g/t Ag from 110m was also intersected, adding further depth to the mineralised system.
Surface to depth — a connected high-grade system
The geological significance for investors is the continuity of high-grade mineralisation from surface through to drilling depth approximately 100m down-dip. The chain of evidence runs from surface channel sampling (6m @ 15.3 g/t Au) and historic adit sampling (4m @ 19.0 g/t Au, 34 g/t Ag) through to the RAV26011 drilling result. The drilled high-grade zone is associated with a strong >60 mV/V IP chargeability anomaly, while a second untested high-chargeability target immediately to the south also exceeds >60 mV/V, providing clear vectors for the next drill campaign.
The initial Ravni epithermal discovery was defined by surface channel sampling, including the 6m at 15.3 g/t Au interval at Drenjak that now connects directly to the RAV26011 drill result approximately 100m down-dip.
Mark Freeman, CEO, Bindi Metals
“The final assays from RAV26011 have materially strengthened the Drenjak result. What we initially reported as 2 metres of high-grade gold has now expanded to an 8 metre mineralised interval grading 13.1 g/t gold, including 2 metres at 42.3 g/t gold. Importantly, this is not an isolated high-grade intercept…”
Understanding high-grade epithermal gold systems
Epithermal gold systems form when hot, mineral-rich fluids rise through fractures in the earth’s crust and deposit metals at relatively shallow depths, typically within 1–2km of the surface. Grades above 10 g/t Au are considered exceptional in the industry, where most open-pit operations target grades below 1–2 g/t Au. The Drenjak intersections, with intervals grading 13.1 g/t, 30.0 g/t, and 42.3 g/t Au, place this system firmly in high-grade territory.
Induced Polarisation (IP) geophysics is a ground-based survey technique that measures how well rocks temporarily store an electrical charge. Sulphide minerals, which are commonly associated with gold mineralisation in epithermal systems, produce a strong “chargeability” response measured in millivolts per volt (mV/V). A reading above 60 mV/V is considered a strong response and flags a priority exploration target.
At Drenjak, the drilled high-grade zone sits directly within one such anomaly. The fact that a second >60 mV/V target immediately to the south remains entirely untested gives the follow-up drilling program a clear, geophysically defined priority.
Beyond Drenjak — what else the maiden program delivered
Rudnjak North — silver and nickel-cobalt upside
All assays from the Rudnjak North prospect have been received. The best result from RAV26010 was:
- 5m @ 71.1 g/t Ag, 0.01% Mo from 112.8m, including 1m @ 341 g/t Ag
All three drill holes at Rudnjak North intersected wide zones of vuggy silica, pyrite and breccia over >80m, an alteration assemblage interpreted as the upper levels of a high-sulphidation epithermal system. This supports the potential for additional mineralisation at depth. The same hole (RAV26010) also intersected a near-surface zone of Ni-Co laterite mineralisation:
- 16.4m @ 1.1% Ni, 0.05% Co from 17.6m
This represents a separate mineralisation style associated with weathered ultramafic rocks at Rudnjak North and provides an additional exploration target distinct from the epithermal system.
Bucje — a new large-scale gold target identified
Surface channel sampling at the Bucje prospect, which has not previously been drilled, returned wide zones of stockwork gold mineralisation associated with diorite intrusive contacts:
- 24m @ 0.2 g/t Au, including 2m @ 1.0 g/t Au, 3.6 g/t Ag, 0.2% Cu (open along strike)
- 6m @ 0.5 g/t Au
- 22m @ 0.2 g/t Au, including 14m @ 0.3 g/t Au
The scale context is compelling. Surface mineralisation sits within an 800m x 300m gold-in-soil anomaly, with a second 600m x 700m anomaly located to the north, totalling approximately 2km of soil anomalies along the diorite intrusive contacts. Both channel sampling intervals remain open along strike, and Bucje is a target for potential drill testing.

What’s next for Bindi Metals at Ravni
With all maiden assays now in hand, Bindi has a complete dataset across multiple prospects to work with. The company’s disclosed next steps are:
- Integrate drilling, geological, geochemical and structural data to refine the geological model and prioritise follow-up drill targets.
- Continue the regional summer exploration programme while finalising the next phase of drilling design.
- Complete permitting and design of follow-up drilling to test extensions at Drenjak, including the two identified IP anomaly targets, and other priority targets identified from the maiden programme.
The Ravni Project sits within the Kopaonik Metallogenic Zone, Raska Mining District of south-western Serbia, part of the western Tethyan Magmatic Belt. This is a globally significant mineral province that hosts major deposits including the approximately 8.6 Moz AuEq Rogozna deposit. With a full dataset now assembled, the company is focused on converting exploration signals across Drenjak, Rudnjak North, Rujak, and Bucje into defined drill targets.
