Data Verification

For drill core sampling, samples were taken from the HQ core by sawing the drill core in half, with one-half sent to ALS Labs Colombia for sample preparation and to ALS Peru (collectively "ALS") for assaying and the other half of the core retained at the site for future reference. Samples were taken systematically at 1.5 m intervals. ALS is a commercial laboratory certified to ISO 9001:2015 by IQNet and accredited to ISO/IEC 17025 by the Standards Council of Canada. The sample preparation facilities are located in Medellín, Colombia, while analytical services are provided in Lima, Peru. ALS is independent of GoldMining. GoldMining has implemented a quality assurance and quality control program for the sampling and analysis of drill core samples, including pulp duplicates, mineralized standards and blank samples for every 20 samples; coarse duplicates for every 100 samples and field duplicates for every 50 samples. The gold analyses are completed by the FA Au-AA24 method (fire-assay with an atomic absorption finish on 50 grams of material). Silver and copper assays are completed by the ME-ICP61 method (four-acid digestion with an ICP-AES finish).
