SAN LORENZO PROVIDES DRILLING PROGRAM RESULTS FROM THE ARCO DE

ORO ZONE IN CHILE

CALGARY, ALBERTA, October 5, 2022 – San Lorenzo Gold Corp. (“ San Lorenzo ” or the

“Corporation”) (TSXV – SLG, OTCQB - SNLGF) is pleased to provide assay results from the

three (3) holes targeting the ‘Arco de Oro’ zone of its Salvadora Copper-Gold-Silver property in

Chile (please see San Lorenzo press release dated June 15, 2022). Results from the holes drilled

into the Cabello Muerto porphyry target are expected to be released in approximately 1 week.

All three of the new holes targeting the Arco de Oro (“ADO”) zone cut copper-gold-silver

mineralization, including locally free gold, across the Feliz Retiro and Arco Primero epithermal

vein systems (see Table 1). As a result, gold-silver-copper mineralization has been confirmed

over a strike length of 1 kilometer and vertical depth of over 300m in the Feliz Retiro system.

Both systems are open to the NW and SE and at depth and can be identified by shallow

artisanal mining over a strike length of over 3 kilometers.

Previously holes completed in 2016 and 2018 by San Lorenzo in the Feliz Retiro system also

Figure 1 - Salvadora ADO drill hole locations (2022 drill holes in Red).

The Feliz Retiro and Arco Primero epithermal vein systems are located within the 500-700m

wide, 3 km long open-ended ADO zone. Their mineralogy and the wall rock alteration in the

deeper holes 04-22 and 07-22 suggests that they may be related to an underlying copper-gold

porphyry system indicated by a large underlying IP/Resistivity anomaly.

Commenting on the Arco de Oro assay results, Terence Walker, San Lorenzo’s VP Exploration

stated: “The 3rd Phase drill program on the Arco de Oro zone of the Salvadora property yielded

excellent results in the epithermal vein systems, making it a valued asset of San Lorenzo by

itself. Of further importance, the drill results provide strong evidence in the form of metallic

minerals present, associated hydrothermal alteration and host rock type to support the presence

of a copper-gold porphyry system with the ADO zone.”

Additional Pending Results

The 2022 drilling program also included drilling in the Caballo Muerto Zone (“CMZ”). The CMZ

is one of four porphyry Cu-Au-Mo style alteration zones identified by geological mapping, soil

and rock geochemical surveys and the 4 Induced Polarization (“IP”) surveys San Lorenzo has

conducted to date – those results are pending and will be released shortly

Figure 2 – Salvadora Property Drill locations (2022 drill holes in Red)

The Salvadora Property is located 15km to the SW of the El Salvador Porphyry Cluster and

Copper Mine on the same metallogenic belt and the exploration program to date exhibits

several similar characteristics. The El Salvador mine has been in operation since 1959 and

recently broke ground on a $1.4B expansion to extend production to 2064.
