Rock Sample and Trench Sample Analytical Procedures
All rock samples collected between 2020 and 2022, with the exception of samples 006801 to 007463 and 006706 to 006736, were analysed at ALS Laboratories in Yamoussoukro. The samples were prepared using ‘’PREP-31B’’ (Crush to 70% less than 2mm, riffle split off 1kg, pulverise split to more than 85% passing 75 microns). After which samples were analysed for gold using ‘’Au-AA26’’ (by fire assay and AAS 30g sample) and for multi-element assay using ‘’ME-ICP61’’.
All samples analysed at the SGS facility in Yamoussoukro using a 50 g Fire Assay with an AA finish (FAA505 with prep code PRP87). Samples assaying greater that 5.0 g/t Au were re-submitted for Fire Assay with Gravimetric finish (FAG505). Those values were considered final. All QAQC control samples returned values within acceptable limits. SGS is 17025 accredited and are completely independent from Kobo.
RC Sampling Analytical Procedures
One meter composite samples of RC chips were sent to the MSA Labs facility in Yamoussoukro where the entire sample was dried and split into 500 g subsample for analysis (prep code CRU-CPA). Sample splits were then analysed for gold using PhotonAssayTM (CPA-Au1). QAQC procedures for the drill program include ion of a certificated standards every 20 samples, a blank every 20 samples and a duplicate sample (split of the 1 m original sample) every 20 samples. All QAQC control samples returned values within acceptable limits. MSALabs are ISO 17025 and ISO 9001 certified and are completely independent from Kobo.
