Reyna Silver Corp. shared results from ExploreTech's Artificial Intelligence (AI) optimization of existing geophysical data from the Guigui Project in Chihuahua, Mexico. ExploreTech's proprietary AI algorithms highlight a strong, multi-layered magnetic anomaly southeast of the 0.5 sq.

kilometre sulphide-mineralized skarn footprint identified in 2022 drilling. The results reinforce existing geological thinking that the intrusive source for the district lies in that area and greatly enhance the area's potential. Pads to drill the target are already permitted and accessible.

The Guigui Project covers the southern part of the Santa Eulalia District -one of the world's largest Carbonate Replacement Deposits ("CRDs") with over 500 Million ounces of historical silver production. Reyna's CRD exploration model indicates that the intrusive source and proximal mineralized skarn for the system remain to be found, and ExploreTech's AI approach to modeling the existing geophysics is specifically designed to augment surface-based geological work to locate that intrusive source beneath extensive, but thin, pre-mineral volcanic rock cover. ExploreTech's platform first uses AI to identify and locate where a geophysical anomaly actually is and then design the optimum hole geometry to hit it.

The first step searches a geophysical survey dataset and calculates thousands of possible explanations for anomalies measured at the surface. For CRDs, the search focuses on solutions most likely to be caused by a source intrusion. This process generates thousands of candidate models that the program then evaluates in 3 dimensions to determine the optimal drilling trajectory to pierce as many of these potential intrusion-related anomalies as possible.

The thin volcanic layer obscuring the Carbonate rocks (limestone) is in dark green. The optimized drill hole aims to intersect the highest percentage of the optimized geophysics layers possible.
