The first two holes at Arco de Oro were drilled on IP line D8 – a line completed during the summer of 2025
that stepped out 3.9 km to the northwest of the Arco de Oro “core zone. The hole locations in relation to
an IP chargeability anomaly on line D8 are illustrated below:

San Lorenzo has not yet received assay results from the upper (surface to 223. 0 metres) portion of the
hole and are expected within the next 2 weeks.
Commenting on the partial results from hole SAL 09 – 25, Terence Walker, San Lorenzo’s VP of Exploration
commented: “It is gratifying to see the trend continue fully 3.9 km further northwest from the
northernmost hole we drilled previously on Arco. We look forward to complete results from Hole SAL 9
– 25 and the numerous other nearby holes that have now been drilled in the Arco northwest extension”.

Cerro Blanco Target
Three holes (SAL 05 – 25, SAL 06 – 25 and SAL 07 – 25) were drilled on the westerly extension to IP line C2
that was completed during the summer of 2025. Results from those holes are presented below:

The location of the three holes drilled on the west side of the Cerro Blanco litho-cap feature, together
with their relation to IP line C2, are illustrated below:
The 3 Cerro Blanco holes drilled on the west side of the litho-cap feature followed the drilling of hole SAL
04 – 25 on the east side of the litho-cap feature (see San Lorenzo press release dated January 26, 2026).
Commenting on Cerro Blanco, Terence Walker commented: “Indications are that the Cerro Blanco system
is stronger on the east side of the litho-cap featur e. However, and based on the overall width of the
mineralized intercepts we have received, the recent holes on the west side confirm the significant breadth
of the Cerro Blanco system. We look forward to continued drilling at Cerro Blanco”.
Drilling Continues
The 13th hole of the ongoing drill program is underway - it being the 9th hole at Arco de Oro. Management
of San Lorenzo has expanded the scope of the Arco de Oro drilling program to include the testing of several
anomalies identified in San Lorenzo’s 2018 IP program

Additional Assay Information
San Lorenzo expects that assay results from the holes already drilled on the Arco de Oro target will be
available on a regular basis over the coming months. San Lorenzo looks forward to providing
stakeholders with regular updates as assay results are obtained. The correlation between sample
intervals and true widths are unknown as the systems are still being modeled.
Qualified Person
The scientific and technical information contained in this news release has been reviewed and approved

Testing Procedures
Samples consisting of 50% of the HQ core are delivered to the ALS Laboratories in Copiapó by San
Lorenzo staff for preparation which consists of drying and crushing to a 2 mm mesh and then pulverized.
The sample material is then delivered to ALS’s facilities in Lima, Peru for gold analysis using the fire
assay method. Samples also analysed by aqua-regia digestion to analyse for other elements including Ag
and Cu.
Drill Hole and Assay Data
Drill collar data, including individual assay results from each of the holes presented in this news release,
will be available on San Lorenzo’s website: www.sanlorenzogold.ca under the Salvadora sub-heading
“Drill Hole and Assay Data”.
About San Lorenzo
San Lorenzo is focused on advancing its flagship Salvadora property located in Chile’s mega-porphyry belt
