MetalsGrove Mining has materially de-risked its West African exploration play, turning its Vavoua permit in Côte d'Ivoire into a growing pipeline of drill-worthy gold targets.
First-pass exploration has generated three fresh gold target areas, headlined by the newly defined 35-square-kilometre Dubaso prospect. The program also used termite mound sampling in difficult terrain to add two more targets along a major mineralised corridor.
At Dubaso, in the northern part of the permit, broad-spaced soil sampling has outlined a coherent cluster of low-order gold anomalies ranging from two parts per billion (ppb) to 10ppb gold, with a peak result of 90ppb.
Management says the anomalies also coincide with multiple zones of quartz veining - a classic host for gold mineralisation - along a 4.5km-wide belt of sheared intermediate volcanic rocks.
The work has elevated Dubaso from a broad geochemical response into an emerging prospect and the centrepiece of the company's exploration efforts. A tighter 400m-by-100m infill soil program is underway while geological mapping and rock-chip sampling continue to define the trends.
In the southwest, where heavily weathered soils reduced the effectiveness of conventional sampling, the company deployed a different technique. Orientation work determined that termite mound sampling was the optimal method to see beneath the surface cover.
Termites bring deep subsurface material from up to 15m below surface, providing a cost-effective window into what treasures may be lurking beneath. The technique was adopted because intense weathering in the southwest had largely stripped away the gold signature that conventional soil sampling relies on.
The approach has already paid dividends, identifying two gold-anomalous areas on a major regional shear zone. The southern anomaly covers about 10 square kilometres, while the northern anomaly spans five square kilometres and remains open to the north.
MetalsGrove managing director and chief executive officer Lijun Yang said: "These results not only expand our pipeline of exploration targets but also provide valuable insights into the most effective techniques for advancing exploration across the project. We are rapidly advancing multiple target areas and continue to build confidence in the broader gold potential of our Central West gold project in Côte d'Ivoire."
Notably, the work has given MetalsGrove a clearer exploration playbook, showing where traditional soil sampling works best and where termite mounds can uncover concealed targets.
The Vavoua permit forms part of the company’s 1315-square-kilometre Central West gold project, with the Vavoua grounds covering more than 378 square kilometres. The project sits in proven elephant country within Côte d'Ivoire’s richly endowed Oumé–Fetekro Birimian greenstone belt, along the Abujar–Napié gold trend, which hosts several major deposits, including the 3.8-million-ounce Abujar gold mine and the 1.2-million-ounce Napié gold project.
Together, MetalsGrove's permits form a district-scale land package with similar geology and multiple structural targets, leaving plenty of room for new discoveries across the Central West gold project.
Despite sitting on one of West Africa's most fertile gold corridors, much of MetalsGrove's ground has seen little modern systematic exploration, leaving considerable room for new discoveries.
While neighbouring Ghana, Burkina Faso and Mali have traditionally dominated investor attention, Côte d'Ivoire has emerged as one of Africa's hottest gold jurisdictions. The country remains comparatively underexplored despite hosting 35 per cent of the famed Birimian rocks, one of the world's premier gold provinces.
With its exploration model now validated, MetalsGrove is preparing a broader 800m-by-100m step-out soil program at Dubaso pending assay results. Geological mapping, rock-chip sampling, additional termite mound work and auger drilling are also being rolled out to generate drill-ready targets.
Having turned a simple patch of dirt into a trifecta of compelling gold targets, MetalsGrove has shown its exploration approach can deliver results.
With multiple targets emerging across Vavoua and follow-up programs underway, punters will likely be keeping a close watch to see whether these geochemical clues evolve into a genuine West African discovery story.
