The 2021 resource models used ordinary kriging (OK) grade estimation within a three-dimensional block model with mineralized zones defined by wireframed solids and constrained by pits shell for Sewum, Boin and Nyam. Kwakyekrom used Inverse Distance squared (ID2).
3.
A base cut-off grade of 0.2 g/t Au was used with a capping of gold grades varied by deposit and zone.

A US$1,650/ounce gold price, open pit with heap leach operation was used to determine the cut-off grade of 0.2 g/t Au. Mining costs of US$1.40 for oxide, US$2.10 for transition, and US$2.60 for fresh rock per mined tonne and G&A and milling costs of US$6.83/milled tonne. The Inferred Mineral Resource Estimate is pit constrained.
