SAN LORENZO COMPLETES SECOND PHASE OF DRILLING ON ARCO DE ORO TARGET OF THE SALVADORA

GOLD-COPPER PROJECT IN CHILE

CALGARY / January 29, 2025 / San Lorenzo Gold Corp. ("San Lorenzo" or the "Company") (TSXV: SLG) is

pleased to report that the second phase of the recently announced diamond drilling program – on the

“Arco de Oro ” target of the Company’s Salvador Gold-Copper Project in Chile - has been successfully

completed.

Arco de Oro Drilling

A minimum of two holes were planned, with a third hole dependent on results from the first two. The

third hole was successfully drilled, bringing the total to 891 metres completed on Arco de Oro during the

second phase.

San Lorenzo previously drilled five holes that cross-cut the Arco de Oro system. Those prior holes

established a strike length of approximately 1 km. The current program aims to extend this strike length

in both the NW and SE directions. San Lorenzo’s IP has identified a significant chargeability anomaly under

the Arco de Oro system which appears to be stronger in the NW direction.

Drilling Indicators

San Lorenzo’s VP, Exploration, Terence (Terry) Walker stated, “We are pleased with the mineralization

and alteration exhibited in core from drilling on Arco de Oro. We eagerly await the assay results which

will be forthcoming in 4-5 weeks due to lab backlogs in Chile. We are especially interested in determining

the validity of the chargeability anomaly which appears stronger towards the NW”.

The Arco de Oro Trend

Arco de Oro is a high priority target. Approximately 1 km of strike length on a system of epithermal veins

has been confirmed by drilling conducted by San Lorenzo thus far and surface artisanal workings infer that

an additional 1.5 km of strike may exist on the Arco de Oro trend. This drilling program was designed to

test NW and SE extensions.

Additional Drilling – Tres Amigos

San Lorenzo has commenced the permitting process with Sernageomin (the Chilean mining regulator) for

an expanded multi -hole program on Tres Amigos - an exciting and significant third target area on the

Salvadora property insofar as hole SAL 06-16 returned the following significant results:

Hole # From (m) To (m) Width (m) Cu % Au g/t

SAL 06-16 36 70 34 1.48 0.22

including 48 54 6 5.71 0.1

and the follow-up hole SAL 02-18 – located approximately 500 metres north of SAL 06-16 – returned the

following significant results:

Hole # From (m) To (m) Width (m) Cu % Au g/t

SAL 02-18 59 109 60 0.47 0.17

including 75 107 33 1.07 0.37

San Lorenzo looks forward to updating shareholders on its activities at Tres Amigos – a system that is open

in both directions - later in Q1, 2025.

About San Lorenzo

Sam Lorenzo is focused on advancing its Salvadora property located in Chile’s mega-porphyry belt. Results

obtained from drilling programs already conducted on 4 different targets to date have convinced

management that several significant gold and copper enriched epithermal and porphyry style systems

underly the Salvadora property.

San Lorenzo looks forward to continuing to provide assay results from drilling completed at Salvador in

the coming weeks.
