A further 22 drill holes, totaling 9,816 meters, have been completed at the Sunbird deposit as part of the underground resource confidence infill and extension drilling program. All drill holes were completed after the June 30, 2025 data cut-off date used for reporting the current Seguela Mineral Resources and Mineral Reserves. Drilling focused on extending the lower shoot and has successfully delineated high grade gold mineralization approximately 400 meters beyond the existing Mineral Resource and Mineral Reserves envelopes, with results including 13.0 g/t Au over an estimated true width of 4.2 meters from 686 meters depth in drill hole SGDD149.
Quality Assurance & Quality Control (QA - QC) All drilling data completed by the Company utilized the following procedures and methodologies. The residual 87.5% samples were stored at the drill site until assay results were received and validated. All diamond drilling (DD) drill holes started with HQ sized diameter, before reducing to NQ diameter diamond drill bits on intersecting fresh rock.
