en.Wedoany.com Reported - San Lorenzo Gold Corp. (TSXV: SLG, OTC: SNLGF) announced progress in drilling tests at the "San Juan Extension Zone" of the Arco de Oro epithermal system within its Salvadora mining concession in Chile, confirming a significant expansion of mineralization and key strike extensions.

The four holes drilled in this program are located along strike approximately 3.4 to 3.9 kilometers northwest of the Arco de Oro "Central Zone," targeting extensions of the epithermal vein system previously identified in the central area. All holes intersected vein systems extending to the surface and surrounding mineralized rock. Each hole encountered multiple mineralized intervals, with detailed results as follows: Hole SAL-11-25 intersected 18.9 meters from 48.3 to 67.2 meters grading 1.06 g/t gold, 2.6 g/t silver, and 0.13% copper, including a high-grade interval of 1.6 meters from 57.5 to 59.1 meters grading 5.68 g/t gold, 22.3 g/t silver, and 0.95% copper; additionally, the hole intersected 16.0 meters from 109.2 to 125.1 meters grading 0.46 g/t gold, 0.3 g/t silver, and 0.04% copper, and 4.1 meters from 271.0 to 275.1 meters grading 0.42 g/t gold, 0.3 g/t silver, and 0.04% copper. Hole SAL-12-25 intersected 21.5 meters from 68.5 to 90.0 meters grading 1.32 g/t gold, 1.7 g/t silver, and 0.12% copper, including a high-grade interval of 3.1 meters from 77.4 to 80.5 meters grading 5.82 g/t gold, 3.4 g/t silver, and 0.53% copper; the hole also intersected 45.0 meters from 113.5 to 158.5 meters grading 1.24 g/t gold, 0.3 g/t silver, and 0.11% copper, including high-grade intervals of 4.6 meters from 122.2 to 126.8 meters grading 5.22 g/t gold, 0.3 g/t silver, and 0.47% copper, and 3.0 meters from 140.5 to 143.5 meters grading 5.68 g/t gold, 0.2 g/t silver, and 0.51% copper; furthermore, the hole intersected 24.0 meters from 168.5 to 192.5 meters grading 0.34 g/t gold, 0.4 g/t silver, and 0.03% copper. Hole SAL-13-25 intersected 23.0 meters from 31.5 to 54.4 meters grading 1.41 g/t gold, 7.8 g/t silver, and 0.12% copper, including a high-grade interval of 1.2 meters from 49.1 to 50.3 meters grading 9.52 g/t gold, 103.0 g/t silver, and 0.79% copper; the hole also intersected 12.0 meters from 95.5 to 107.5 meters grading 1.15 g/t gold, 1.1 g/t silver, and 0.09% copper; and 8.3 meters from 174.2 to 182.5 meters grading 1.71 g/t gold, 1.1 g/t silver, and 0.14% copper, including a high-grade interval of 0.7 meters from 177.8 to 178.5 meters grading 9.73 g/t gold, 8.4 g/t silver, and 1.07% copper. Hole SAL-14-25 intersected 13.3 meters from 35.2 to 48.5 meters grading 1.56 g/t gold, 9.5 g/t silver, and 0.19% copper, including a high-grade interval of 1.4 meters from 40.9 to 42.3 meters grading 9.85 g/t gold, 73.2 g/t silver, and 1.39% copper.

The above holes confirm epithermal mineralization over an additional 0.5-kilometer segment at the San Juan outlet, located approximately 3.4 kilometers northwest of the Arco core zone. Previous drilling in the central zone defined mineralization over approximately 1 kilometer of strike, and this drilling has significantly extended the known mineralized strike length of the entire Arco de Oro system. The company believes that comprehensive geological information indicates mineralization potential along a cumulative length exceeding 7.5 kilometers, with the system remaining open to the northwest of San Juan, and artisanal mining signs extending 2.6 kilometers into its concession area.

San Lorenzo believes that the formation of the epithermal system in the area is related to large intrusive activity, a view supported by recent IP surveys and drilling results from holes SAL-09-25 and SAL-10-25, the latter two of which appear to have penetrated the gold-rich upper levels of a copper-gold porphyry mineralization system. The company is advancing its Phase 7 drilling program, initially planned to commence at the Cerro Blanco target, which aims to follow up on positive results from previous holes SAL 01-25 and SAL 04-25 and test newly identified IP anomalies. Meanwhile, the Arco de Oro target is also a priority for drilling. Currently, San Lorenzo has initiated an extensive IP survey program, including at least 50 kilometers of additional lines, while simultaneously conducting soil and rock sampling. The company has obtained all necessary permits, and drill pad construction began approximately 10 days ago, with plans to deploy three drill rigs to advance exploration at the project.

Terence Walker (M.Sc., P. Geo.), Vice President of Exploration at San Lorenzo, as the Qualified Person as defined by National Instrument 43-101, has reviewed and approved the scientific and technical information in this news release. All samples were delivered by company personnel to the ALS laboratory in Copiapó for preparation, including drying, crushing to 2 mm mesh, and pulverizing, followed by gold analysis using fire assay at the ALS facility in Lima, Peru, and analysis for other elements such as silver and copper using aqua regia digestion.
