30 Second Briefing
Montage Gold is positioning the Didievi project in central Côte d’Ivoire as its next development asset after a 40,000-metre drill campaign at the Blaffo Guetto deposit returned standout intercepts including 15 metres at 20.97 g/t gold from 127 metres and 27.4 metres at 8.46 g/t from 184 metres. Didievi currently hosts 12.4 million inferred tonnes at 2.5 g/t (989,000 oz) and a 60,000-metre, US$13.5 million follow-up programme is under way to extend the >1.3 km strike and update resources across 14 targets. Analysts see potential for c.200,000 oz/y production, complementing Montage’s Koné mine, which is expected to exceed 300,000 oz/y over its first eight years.
Technical Brief
- Follow-up 60,000 m drill programme at Didievi is budgeted at US$13.5 million, completing by year-end.
- Highlight hole BGDD26-090 intersected 15 m at 20.97 g/t from 127 m and 13 m at 4.75 g/t from ~168 m.
- Second key hole BGDD26-093 cut 27.4 m at 8.46 g/t from 184 m depth in the same zone.
- Additional hole BGRC26-095 returned 8.5 m at 15.44 g/t from 152 m and 18 m at 3.75 g/t from 265 m.
- Drilling at Blaffo Guetto has now traced high-grade mineralisation along >1.3 km strike and down-dip.
- Mineralisation at Blaffo Guetto remains open along strike and at depth, with high-grade lenses confirmed as continuous.
- Fourteen targets have been defined across the Blaffo Guetto, Pranoi and Pokou trends for ongoing resource expansion drilling.
- Environmental and social impact assessment work is already under way to support fast-tracked permitting and development sequencing.
- Didievi lies ~35 km from Yamoussoukro within a greenstone belt hosting several operating gold mines, supporting regional infrastructure synergies.
Our Take
The high‑grade intercepts at Blaffo Guetto (including multiple intervals above 8 g/t gold over mineable lengths) contrast with Koné’s lower‑grade bulk‑tonnage profile described in the March and May 2026 items, suggesting Montage could ultimately blend or sequence a higher‑margin satellite feed into a large‑scale central plant model.
Montage’s acquisition of African Gold and rapid follow‑up at Didievi comes on top of new greenfield permits in Mauritania reported in April 2026, signalling a deliberate strategy to lock up West African gold optionality rather than remain a single‑asset Côte d’Ivoire producer once Koné is in steady state.
