2024 Diamond Drill Program and 2024 Auger Drill Program

Sampling, Analysis and Data Verification

Drill core samples were taken from the NQ/HQ core by sawing the drill core in half, with one-half sent to SGS Geosol Laboratórios Ltda. ("SGS") in Brazil for assaying, and the other half of the core retained at the site for future reference. Sample lengths downhole were uniformly 1.0 m.

Auger drilling samples were collected at 1 m sample intervals, with the material being dried, homogenized and split in the field to obtain a 1 kg representative sample which was sent to SGS for analysis. The remaining auger sample material is stored until the lab results are received, and a 1 kg sample duplicate is maintained in the archive.

SGS is a certified commercial laboratory located in Vespasiano, Minas Gerais, Brazil, and is independent of GoldMining. GoldMining has implemented a quality assurance and quality control program for the sampling and analysis of drill core and auger samples, including duplicates, mineralized standards and blank samples for each batch of 100 samples. The gold analyses were completed by FAA505 method (fire-assay with an atomic absorption finish on 50 grams of material).
