CALGARY – TheNewswire - March 17, 2025 - San Lorenzo Gold Corp. ("San Lorenzo" or the "Company") (TSXV: SLG) is pleased to announce assay results from the second and third recently drilled holes on its Cerro Blanco gold/copper porphyry target.  Cerro Blanco is located within San Lorenzo’s flagship Salvadora property in Chile.

San Lorenzo’s VP Exploration, Terence Walker commented on the Cerro Blanco results: “this was a wide spaced reconnaissance program.  We are pleased that all three holes returned significant grades of gold.  The locations of Holes 1, 2 and 3 support the fact that Cerro Blanco is a sizeable feature.  Of note is the fact that gold mineralization - including grades up to 1.08 g/t in hole 3 - were encountered at the bottom of each hole.  Therefore, in addition to the significant aerial extent suggested from the locations of the 3 holes, the feature remains open at depth and in virtually all directions”.

San Lorenzo’s CEO Al Kroontje noted that “the three holes in the maiden drill test of the Cerro Blanco target area were sited to test varied combinations of IP chargeability and surface geochemistry.  All three holes, located roughly 500 metres from each other, reported substantial gold intercepts, highlighting Cerro Blanco as a large and well-mineralized system.  The target area is large and still open in most directions.  We look forward to exploring Cerro Blanco more intensively and expanding the areas of mineralization, given its obvious potential to host a large gold/copper resource.”

Cerro Blanco Assay Results

The table below provides the assay results from Hole SAL 02-24 – the second hole drilled on Cerro Blanco:

Cerro Blanco Feature Preliminary Interpretation

Terence Walker, San Lorenzo’s VP of Exploration, provided the following preliminary interpretation of the core logs and the assay results from the 3 holes and provides San Lorenzo’s thoughts on next steps:

The alteration types observed in the local intrusive and volcanic rocks, in core from all three holes plus the underlying IP/Chargeability anomalies indicate the presence of a local gold/copper enriched porphyry deposit at Cerro Blanco similar to those at the nearby El Salvador mine complex. Core logs from the lower 25 to 30 meters of hole 3 contain weak potassic alteration suggesting the start of the transition into the more copper-rich core of the system - typical of the significant porphyry systems that have been discovered in the mega-porphyry belts of Chile.

As results continue to correspond exceedingly well with our IP interpretation, additional IP coverage is warranted.  The additional coverage will involve infill lines as well as lines extending coverage to the east, north and south of existing coverage. The current chargeability anomalies are open in several directions.  Plans to begin such additional IP coverage have been initiated.

Summary:  Cerro Blanco is a two-by-two km area of anomalous copper/gold soil and rock geochemistry, IP chargeability anomalies and an exposed litho-cap that San Lorenzo believes overlays a mineralized porphyry center.  Mineralization in all three holes continued to the bottom of each hole, indicating that the mineralized system remains open to depth.  Additional IP and drilling is very much warranted.

Warrant Exercise

San Lorenzo is pleased to advise that essentially all outstanding share purchase warrants and broker warrants were exercised prior to their expiry on March 13, 2025.  Total proceeds of $1,505,645 were received.  No commissions or other fees were payable in respect of the warrant exercises.

Next Steps

Management is planning a significant and aggressive follow-up IP and drilling program utilizing the warrant exercise proceeds.  IP will be obtained at Cerro Blanco and further drilling on both Cerro Blanco and Arco de Oro will be conducted.  Drilling is also planned for the Tres Amigos copper-rich epithermal system during the next drilling campaign at already-identified locations.

Sample Acquisition, Handling, Analysis and Qualified Person

All drill core logging, sample selection and cutting, followed by bagging and delivery of 50% of the HQ core to the ALS lab in Copiapó, was carried out by San Lorenzo staff under the on-site supervision of Eric Hanson P. Geo. or Terence Walker, P. Geo., each a “qualified person” for purposes of NI 43-101.  All assays were conducted by ALS Patagonia Limited.  Samples were crushed and screened to -80 mesh and analyzed using their multi-element ICP after aqua-regia digestion.  Gold was analyzed by fire assay atomic adsorption.  ALS included standard check sampling techniques including blank and duplicate insertions.

All samples presented in the map are continuous chip samples of 1 – 2 meters in length taken under the direct field supervision of either Eric Hansen, P Geo. or Terence Walker, P. Geo, each qualified persons for purposes of National Instrument 43-101.  All geophysical (IP) data was collected by Geoexploraciones SA (“GeoSA”), a well-established geophysical contractor. Interpretation of the data was performed by GeoSA with the resulting anomalous areas added to the map by Terence Walker.

Terence Walker, P. Geo. and QP, has reviewed and approved the contents of this release.

Arco de Oro Assays

San Lorenzo expects that remaining assay results from Arco de Oro will be received during the next approximately 1 week.

About San Lorenzo

Sam Lorenzo is focused on advancing its flagship Salvadora property located in Chile’s mega-porphyry belt.  Results obtained from drilling programs already conducted on 4 different targets have convinced management that several significant gold and copper enriched epithermal and porphyry style systems lie within the boundaries of the Salvadora property.
