San Lorenzo Provides Drilling Update from Cerro Blanco Target, Salvadora Project, Chile
SAN LORENZO PROVIDES DRILLING UPDATE FROM CERRO BLANCO TARGET, SALVADORA PROJECT,
CHILE
CALGARY / November 3, 2025 / San Lorenzo Gold Corp. (" San Lorenzo" or the " Company") (TSXV: SLG
and OTC: SNLGF) is pleased to provide an update on drilling operations at its Cerro Blanco porphyry target
- situated on San Lorenzo’s flagship Salvadora property in Chile.
The first HQ diamond drill hole in the current drill campaign was completed to a depth of 485 metres on
October 29, 2025. The hole tested the strong chargeability feature identified during San Lorenzo’s May
2025 induced polarization (“IP”) geophysical survey program, as reported in the Company’s news release
dated June 17, 2025.
Initial observations of the first hole ( SAL 04-25) are that drilling intersected mineralization which
correlated well with the IP c hargeability anomaly. The nature and intensity of the mineralization is
comparable to what was observed in San Lorenzo’s first Cerro Blanco drill hole (SAL-01-24) that
intersected 153.5 metres grading 1.04 g/t gold, 1.0 g/t silver, and 0.05% copper and included 3.8 metres
grading 12.78 g/t gold, 6.5 g/t silver, and 0.51% copper as reported in the Company’s news release dated
March 3, 2025.
Commenting on the correlation between mineralization and IP chargeability/resistivity anomalies ,
Terence Walker, San Lorenzo’s VP of Exploration stated: “We are pleased that IP geophysics continues to
be a useful exploration tool for drill target delineation at Cerro Blanco, and indeed, over the Salvadora
property generally. We look forward to continued testing of additional high chargeability IP geophysical
anomalies that have already been identified on numerous targets areas within the Salvadora property.”.
Setup of the drill to the second Cerro Blanco location has been completed. Assay results from the first
hole and additional information related to the current drill program will be reported as available.
