EXPLORATION METHODOLOGY

Key Observations and Learnings from Ancien

▪ The magnetically and geochemically quiet basalt package that hosts Ancien was previously
considered a lower priority for exploration and historically had received little attention.
▪ The discovery of Ancien in this sequence opened up >35 strike kilometres of virtually
unexplored prospective terrain.
▪ Subsequent high-grade discoveries at Koula, Sunbird and Gabbro North are all hosted
in this basalt package.
▪ Significant high-grade gold associated with deformed and altered wallrock and not solely
within massive quartz veins was suggestive of a larger fertile system.
▪ Generally narrow, discrete high-grade quartz veins are ubiquitous throughout the
Birimian and often targeted by small-scale artisanal miners.
▪ The potential of dilationary flexures along strike extensive N-S D1 structures to host high-
grade gold. Ancien is associated with a subtle NNE flexure on just one of these structures,
which traverse all stratigraphic packages on the Séguéla property.

▪ The short strike length (~350m) and southerly-plunging geometry of Ancien highlighted the
AGOUTI
potential significance of single drillhole high-grade intercepts and single point geochemical AGOUTI
anomalies elsewhere in the belt. 88koz @ 2.2 g/t

▪ Ancien was represented by only single point soil (239ppb Au) and auger (178ppb Au)
anomalies.

▪ Implications for sample and drill spacing.
