Aurum Resources has reported gold mineralisation outside the current resource at BST1 and BMT2, including a 57-metre intercept grading 2.34 g/t gold. The results will be assessed in an updated Boundiali resource estimate due by the end of October, ahead of a planned definitive feasibility study.
- 57m at 2.34 g/t gold outside BST1’s current resource
- 28.35m at 2.02 g/t gold at resource-free BMT2
- 25 diamond holes covering 5,651.35m
- Boundiali MRE targeted by end-October 2026
- DFS expected in late 2026, with first gold targeted for H1 2028
BST1 drilling adds a broad zone beyond the resource
Aurum Resources (ASX:AUE) has delivered another batch of results from Boundiali, with its most consequential intercept extending gold mineralisation beyond the current BST1 resource. Hole BSDD0180 returned 57 metres at 2.34 g/t gold from 290 metres, including 2 metres at 37.95 g/t, alongside two additional mineralised zones higher in the same hole.
The latest BST1 drilling covered eight diamond holes for 2,636.55 metres. Other results from BSDD0180 included 38 metres at 0.89 g/t from 215 metres and 13.07 metres at 1.15 g/t from 257 metres. Hole BSDD0183 ended in mineralisation at 333.5 metres, also outside the current Mineral Resource Estimate. The results add to the recent BST1 resource extensions reported by Aurum earlier in October.
BST1 currently carries 22 million tonnes at 0.8 g/t gold for 570,000 ounces. Aurum says the deposit remains open along strike and at depth, with follow-up drilling planned to test mineralisation identified outside the existing resource.
BMT2 produces resource-free gold zones
The more strategically interesting result may be at BMT2, where Aurum has no Mineral Resource currently defined. Five holes totalling 1,182.85 metres produced a 28.35-metre zone at 2.02 g/t gold from 116.45 metres in MBDD515, including 7 metres at 4.80 g/t. The same hole intersected further mineralised zones of 15 metres at 2.31 g/t and 8 metres at 2.73 g/t.
BMT2 also returned narrow, high-grade hits, including 1.5 metres at 31.29 g/t gold from 39 metres in MBDD506 and 1 metre at 12.73 g/t from 243 metres in MBDD515. As with the BST1 results, these are exploration intercepts reported as downhole lengths. Aurum estimates true widths at roughly 60% to 85% of the reported lengths, meaning the eventual resource interpretation will matter more than any single headline interval.
At BMT3, which already hosts 18.6 million tonnes at 1.3 g/t gold for 750,000 ounces, the new drilling returned 10 metres at 2.65 g/t, 25.5 metres at 0.80 g/t and 14.5 metres at 1.10 g/t. The company says mineralisation across the BM tenement remains open along strike and at depth, while the current drilling is intended both to grow the resource and improve its confidence. The earlier BMT2 resource drilling was also aimed at supporting a potential maiden Inferred Resource.
October resource estimate becomes the next test
The 25 holes reported in this release form part of Aurum’s expanded 150,000-metre Boundiali drilling program for calendar 2026. The company has set a 30 September drill-collar cut-off for the next MRE, which is targeted for release by the end of October. The estimate will determine how much of the newly identified mineralisation can be incorporated, and at what classification.
That update is intended to feed a Boundiali Definitive Feasibility Study expected in late 2026. Aurum says it has more than A$95 million in unaudited cash after a recent placement and 16 company-owned diamond rigs. Across Boundiali and Napié, the group reports 4.38 million ounces of Mineral Resources, while a 30,000-metre Napié drilling program is due to commence this quarter.
The company continues to target mining licence grants, a final investment decision and first gold in the first half of calendar 2028. Those milestones remain forward-looking: the new results still need to be interpreted in a resource model, the DFS must establish project economics and capital requirements, and permitting and construction funding remain unresolved steps rather than administrative footnotes.
Bottom Line?
The October MRE will show whether these extensions become additional ounces and higher-confidence material, rather than simply more promising drill intersections.
Questions in the middle?
- How many ounces, and at what classification, will the new BST1 and BMT2 drilling add to the October MRE?
- Can BMT2 support a maiden resource that is material to the Boundiali mine plan?
- What capital, permitting and execution requirements will emerge from the late-2026 DFS?
