SAN LORENZO CUTS 5 SECTIONS OF MINERALIZATION TOTALLING 222.4 METERS

IN FIRST HOLE OF CURRENT DRILLING PROGRAM

CALGARY / January 26, 2026 / San Lorenzo Gold Corp. ("San Lorenzo" or the "Corporation") (TSXV: SLG)

is pleased to provide assay results from the first hole of its current drilling program at Salvadora, San

Lorenzo’s flagship property in Chile.

The results from Hole SAL 04-25, the first hole drilled in the current campaign and the 4th hole drilled at

the Cerro Blanco porphyry target, are summarized in the table and on the drill hole section below:

CERRO BLANCO ASSAY RESULTS - SAL 04-25

The mineralization is assumed to represent the upper levels of a mineralized porphyry system and the

results suggest continuation – to the northeast - of the system encountered in the first two holes drilled

last year on the east side of the Cerro Blanco litho-cap feature.

The location of the three holes SAL 01, 02 and 04 – 25, are displayed on the image below. SAL 04 – 25 is

located approximately 350 meters northeast of SAL 01 - 25 and was drilled on a chargeability/resistivity

anomaly identified during last years’ geophysical program that provided expanded IP coverage on the

Cerro Blanco and Arco de Oro targets located on the Salvadora property.

The image also displays the location of chargeability anomalies on three IP lines at Cerro Blanco (orange

oval) – 2 of which were acquired in 2018 and the middle line acquired in 2025 – and their relationship to

the limited drilling completed so far on the east side of the Cerro Blanco litho-cap feature.

San Lorenzo is hopeful that the system extends further to the northeast (yellow highlight) to where

significant alteration can be seen from the valley floor, 1.7 kilometers to the northeast (image below).

Further IP followed by drilling is warranted and will be undertaken by San Lorenzo.
