San Lorenzo Gold Corp Reports Assay Results from Epithermal Focused Drilling on the San Juan Extension of the Arco De Oro Epithermal System and Provides Exploration and Drilling Update San Lorenzo Gold Corp. has significantly expanded the mineralized footprint and confirmed key strike extensions on the Salvadora property. Assay results from four holes have been received which were drilled on the “San Juan Extension” – a northwest extension to the Arco de Oro “Core Zone”. The four holes were designed to test the epithermal vein system previously intersected by San Lorenzo in the Arco Core Zone located approximately 3.5 kilometers to the southeast. Specifically, the four holes tested the system between 3.4 km and 3.9 km northwest of the nearest hole previously drilled on the Arco de Oro epithermal trend. These results significantly expand the known footprint of the epithermal system at Arco de Oro. The four holes were designed to test shallow epithermal mineralization and not large porphyry targets. Step-outs from holes SAL-10-25 and SAL-09-25 - to test continuity of the porphyry system - are included in the upcoming drilling program due to commence within approximately 7 days. The potential for significant porphyry mineralization at San Juan exists requiring further testing. All four drill holes intersected the epithermal vein system that extends to surface, together with mineralized surrounding rock, generating the following results: SAL-11-25: 18.9m at 1.06g/t Au from 48.3m, including 1.6m at 5.68g/t Au; SAL-12-25: 21.5m at 1.32g/t Au from 68.5m, including 3.1m at 5.82g/t Au, 45m at 1.24g/t Au from 113.5m, including 4.6m at 5.22g/t Au & 3.0m at 5.68g/t Au; SAL-13-25: 23m at 1.41g/t Au from 31.5m, including 1.2m at 9.52g/t Au, 12m at 1.15g/t Au from 95.5m, 8.3m at 1.71g/t Au from 174.2m; SAL-14-25: 13.3m at 1.56g/t Au from 35.2m, including 1.4m at 9.85g/t Au. The four holes have confirmed the presence of epithermal mineralization over an additional 0.5 km of strike at San Juan, which is located ~3.4 km to the northwest of the Arco Core area. Previous drilling at the Arco Core area had already defined mineralization over ~1 km of strike. Drilling has now defined mineralization over a very significant strike length (from the Arco Core Zone to the San Juan extensions). Follow-up drilling is required to confirm continuity between the two. When the available geological information, including drilling, mapping, rock chips, geophysical surveys and artisanal workings is viewed together, it indicates the potential for mineralization over a cumulative potential strike length of over 7.5 km as the epithermal system remains open and untested further to the northwest of San Juan. Surface artisanal workings continue for an additional 2.6 km along trend within San Lorenzo’s Salvadora land package. Follow-up drilling is required to test the system to the northwest to establish the overall continuity and extent of mineralization on Arco de Oro’s epithermal system. San Lorenzo believes that formation of the epithermal systems are related to intrusive features suggested by chargeability and resistivity anomalies evident on San Lorenzo’s historic (2014 -2018) and recent (2025) geophysical induced polarization lines – a belief which has been confirmed by the recent drilling of holes SAL 09-25 and SAL 10-25 which appear to have penetrated the upper gold-rich section of a mineralized porphyry copper-gold system. The images below illustrate: 1) the overall Arco de Oro trend with the locations of the Arco Core Zone and the San Juan Extension shown relative to each other – including an image (inset) of the artisanal workings visible at surface; and 2) A collar location plan indicating the location of the four holes reported on in this news release and their locations relative to holes SAL 09-25 and SAL 10-25.

Similar geo-chemical work has been ongoing on the newly acquired lands east and south of the Cerro Blanco target. In addition, an extensive IP program comprised of a minimum of 50 additional line kms of IP surveying has been initiated. San Lorenzo is in possession of all permits required to commence the next - Phase 7 - drilling program at Salvadora. Drill-pad construction commenced approximately 10 days ago, and the first drilling rig is expected to be mobilized imminently. The Phase 7 drilling program will initially start at Cerro Blanco. Holes are designed to follow up on the very positive results from holes SAL 01-25 and SAL 04-25. Drilling is also planned to test additional IP anomalies that have been defined at Cerro Blanco - specifically to help build an understanding of the geometry of the Cerro Blanco discovery. In addition to drilling at Cerro Blanco, drilling on the Arco de Oro target is a high priority. Drilling will be ramped up with the company working towards having 3 rigs drilling on the Salvador project. New Risk • Jun 08
New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 33% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Share price has been highly volatile over the past 3 months (22% average weekly change). Shareholders have been substantially diluted in the past year (33% increase in shares outstanding). Revenue is less than US$1m. Announcement • Apr 29
