QA/QC

Silver Elephant Mining Corp sends samples to ALS Global Laboratories in Oruro, Bolivia for sample preparation, after which, the prepared pulps are shipped to ALS Global laboratories for analysis in Lima, Peru. Samples are analyzed using Intermediate Level Four acid digestion. Silver over limits ("ore grade") are determined by fire assay with a gravimetric finish for precise quantification. ALS Laboratories sample management system meets all requirements of International Standards ISO/IEC 17025:2017 and ISO 9001:2015. All ALS geochemical hub laboratories are accredited to ISO/IEC 17025:2017 for specific analytical procedures. All samples are collected from HQ and NQ-diameter diamond drill core which is longitudinally halved using diamond-blade masonry saw. One-half of the core is submitted for laboratory analysis, while the other half is preserved on the Company's secured core facility for future reference. All core undergoes geotechnically analysis, photographed and then detail geological logging by the Company's qualified geologists prior to sampling.
