The Kabaya gold mineralization is disseminated and associated with a strong kaolinization. The gold host rock alternates between tuffaceous and greywacke facies crosscut by younger dolerite sills and dykes (Figures 2 and 3). At KB3, the higher-grade zone does not appear at the surface and, from the longitudinal section, the mineralization is plunging around 10-15° to the South. This relatively higher grade has not been captured in our resource estimation (Press Release June 8^th, 2022).

The Kabaya mineralization is part of the prolific regional Siribaya-Mankouke-Seko structural corridor (Figure 4). It is located on the Eastern edge of this major structure as well as Mankouke South gold body. Roscan's large land package has a strategic position covering a substantial portion of this significant structural corridor by over 25km, including the splays around the intrusive pluton of Disse, where several mineralized bodies were discovered.

Drilling and Analytical Protocol

Roscan uses Geodrill Reverse Circulation (RC) to drill until maximum 170m to reach the target. In 2021, (holes RCDBS21-026 to RCDBS21-048), the samples were sent for preparation and 50g fire assays to Bureau Veritas Bamako laboratory and since January 2022, the samples are sent to the ALS Laboratories in Bamako, Mali and assayed at their analytical facilities to Ouagadougou for 2 kg Bottle Roll with atomic absorption finish including tail analysis by fire assays for results more than 0.05ppm. Roscan applied industry-standard QA/QC procedures to the program using reference materials, blanks, standards, and duplicates.
