Goldgroup Mining Inc. Shares Recent Positive Metallurgical Testing Results for Esperanza and Neuva Esperanza Zones At Cerro Prieto Mine Located Near Magdelana, Sonora State, Mexico

Goldgroup Mining Inc. shared recent positive metallurgical testing results for Esperanza and Neuva Esperanza Zones at the Company's 100% owned Cerro Prieto Mine located near Magdelana, Sonora State, Mexico. HIGHLIGHTS Cyanide Agitated Bottle Roll Leach Testing on Composite Samples: Esperanza Zone - Average gold, silver extractions of 78. 03%, and 63. 12% obtained after 72 hours of retention time. Nueva Esperanza Zone - Average gold silver extractions of 82. 07%, and 90. 42% obtained after 72 hours of retention time. Locked Cycle Cyanide Column Testing for 78 days on the Esperanza Composite o The highest gold extraction of 78. 88% with silver extraction of 21. 18% was obtained at a sodium cyanide concentration of 600 ppm and crush size of P80 of 3/8", resulting in, a calculated gold and silver recoveries of 72. 09% and17. 27% respectively (3% Discounted from Column Extraction) x 95% ADR Plant Recovery) Locked Cycle Cyanide Column Testing for 78 days on the Nueva Esperanza Composite. The crush size of P80 of 3/8" gives gold extraction of 77. 30% and silver extraction of 31. 37%, obtained at a sodium cyanide concentration of 600 ppm and crush size of P80 of 3/8", resulting in, a calculated gold and silver recoveries of 72. 09% and17. 27% respectively (3% Discounted from Column Extraction) x 95% ADR Plant Recovery) Metallurgical Test Work in a Certified Commercial Metallurgical Laboratory In May 2024, Cerro Prieto mine site personnel prepared two composites identified as Esperanza and Nueva Esperanza using 1/4 split of HQ drill core samples for conducting a metallurgical study specified and under the direction by Rodrigo R Carneiro MS, a Qualified Person under 43- 101 guidelines, which included: Sample preparation and head screen assays (Au, Ag & Cu) at two crush sizes of P80 of 5/8" and P80 of 3/8", Agitated cyanide bottle roll testing on each composite crushed to 100% minus 10 Mesh (2mm) for 72 hours, Locked cycle column testing on each composite at two crush sizes of P80 of 5/8" and P80 of 3/8" for 78 days. In June 2024, a metallurgical study on the Esperanza Composite and Nueva Esperanza Composite was started at Laboratorio Tecnologico de Metalurgia (LTM) located in Hermosillo, Sonora. LTM is an ISO certified commercial laboratory, and the results obtained in the cyanide agitated bottle roll tests and locked cycle column leach tests on composites of the Esperanza and Nueva Esperanza Composites. The following comments relate to the summary of results obtained on the cyanide agitated leach testing conducted on the Esperanza Composite samples at a particle size of 100% minus 10 Mesh. Average gold, silver and copper extractions of 78. 03%, 63. 12 and 4. 79% respectively were obtained after 72 hours of retention time. Average NaCN and CaO consumptions were 0. 760 kg/t and 1. 958 kg/t respectively, NaCN and CaO consumptions can be considered in the medium range for an agitated leach at a particle size of 100% minus 10 Mesh. Average gold, silver and copper calculated head of 0. 622 g/t, 1. 533 g/t and 50. 10 g/t respectively were obtained on the Esperanza Composite. The following comments relate to the summary of results obtained on the cyanide agitated leach testing conducted on the Nueva Esperanza Composite samples at a particle size of 100% minus 10 Mesh. Average gold, silver and copper extractions of 82. 07%, 90. 42 and 7. 72% respectively were obtained after 72 hours of retention time. Average NaCN and CaO consumptions were 0. 949 kg/t and 2. 120 kg/t respectively, NaCN and CaO consumptions can be considered in the medium range for an agitated leach at a particle size of 100% minus 10 Mesh. Average gold, silver and copper calculated head of 0. 823 g/t, 3. 176 g/t and 66. 42 g/t respectively were obtained on the Esperanza Composite. Locked Cycle Cyanide Column Testing Esperanza Zone Four (4) locked cycle column tests were conducted on the Esperanza Composite at the crush sizes of P80 of 5/8" and P80 of 3/8" for 78 days of leach followed by 4 days of wash cycle and 2 days of drain cycle at a commercial ISO certified metallurgical laboratory. The following comments relate to the column tests conducted on the Esperanza Composite at crush sizes of P80 of 5/8" and P80 of 3/8" using sodium cyanide concentrations in the feed solution of 300 ppm and 600 ppm. The highest gold extraction of 78. 88% was obtained at a sodium cyanide concentration of 600 ppm and the lowest silver extraction of 21. 18%. It seems that an incremental sodium cyanide consumption of 0. 27 g/t obtained at the crush size of P80 of 3/8" and using 600 ppm of sodium cyanide justifies the additional incremental of gold extraction of 6. 97%. Calculated gold and silver recoveries of 72. 09% and 17. 27% respectively were estimated discounted 3% from the column extraction and ADR Plant recovery of 95%. ted 3% from the column gold and silver extractions and ADR Plant recovery of 95%. Locked Cycle Cyanide Column Testing Nueva Esperanza Zone Two (2) locked cycle column tests were conducted on the Nueva Esperanza Composite at the crush sizes of P80 of 5/8" and P80 of 5/8" for 78 days of leach followed by 4 days of wash cycle and 2 days of drain cycle at a commercial ISO certified metallurgical laboratory. The following comments relate to the column tests conducted on the Nueva Esperanza Composite at two crush sizes of P80 of 5/8" and P80 of 3/8". The crush size of P80 of 3/8" shows the highest gold extraction of 70. 58% and the lowest silver extraction of 26. 95%. The additional incremental of sodium cyanide consumption of 0. 06 g/t should justify the additional incremental of gold extraction of 4. 65% obtained at the crush size of P80 of 3/8". Calculated gold and silver recoveries of 70. 58% and 26. 95% respectively were estimated discounted 3% from the column extraction and ADR Plant recovery of 95%. There was not enough sample weight to conduct two column tests using sodium cyanide concentration of 300 ppm.
