Diversified mining portfolio: Gold · Diamond · Copper · Potash — 8 official permits, 4 commodities, assets at various stages of maturity for investors.
4 exploitation permits · Confirmed grades · Dual alluvial and primary potential
Exceptional grades in eluvial deposits. Primary deposit identified linked to quartz veins and porphyroblastic schists — extensive drilling potential.
Gold potential extending over 20 km of waterways. Angular gold grains suggest proximity of a primary source. Production trials conclusive.
Field assessment: several zones (pits P2 and P5) showing highly profitable yields. Targets ready for semi-industrial extraction campaign.
Rare mineralogical association: gold and diamonds present simultaneously. Dual commodity valorisation on a single permit. Gold grades confirmed in the Bibindou River.
Confirmed kimberlitic source · 9 diamonds recovered in prospecting tests · 0.2 to 0.5 ct/m³
Decisive mineralogical analyses: presence of indicator minerals (zircon, tourmaline, garnet, ilmenite) proving a nearby kimberlitic source. 9 diamonds (0.10 to 2 carats) recovered during prospecting tests only — exceptional indicator of subsurface richness.
Strong geochemical anomalies · Iron caps & malachite · Comparable to Katanga (DRC)
Multiple iron caps and malachite/azurite patches identified. Strong copper geochemical anomalies. Sedimentary type comparable to the rich Katanga deposits.
Extension of the Kinkembo deposit. Site ready for deployment of a deep geophysics and drilling campaign to delineate the underlying sulphide mass.
2D seismic completed · Salt top at 320–360 m · JORC certification target · Ideal Joint-Venture
Located in the prolific Congolese coastal basin, near the vast Kola and Holle deposits. The 2D reflection seismic survey is already completed — potassic salt top located at 320–360 m depth. 3-hole drilling programme modelled. "Crown jewel" project ideal for a capital raise or Joint-Venture with a global mining operator.
Qualified staff for every stage of the mining cycle
