San Lorenzo Mobilizes Drilling Equipment to Cerro Blanco Target at Salvadora Copper/GOLD Property, Chile
SAN LORENZO MOBILIZES DRILLING EQUIPMENT TO CERRO BLANCO TARGET AT SALVADORA
COPPER/GOLD PROPERTY, CHILE
CALGARY, AB / December 19, 2024 – TheNewswire – San Lorenzo Gold Corp. (" San Lorenzo " or the
"Company") (TSXV: SLG) is pleased to announce that permits have been obtained and diamond drilling
equipment has been mobilized to the Company’s flagship Salvadora property, located 15 kilometres
(“km”) from the world class El Salvador Copper/Gold (“Cu”/“Au”) porphyry deposit located within Chile’s
mega porphyry belt in the Province of Chañaral, Region III, Chile.
The diamond drilling program will commence immanently and test three separate target areas with up
to seven holes for up to 2,000 metres (“m”). Two of the three target areas, Arco de Oro and Tres Amigo,
have already generated impressive prior drill results such as Hole SAL 04-22 that returned 22.5m of 4.74
g/t Au and 0.18% Cu, that included 6.5m of 16.27 g/t Au and 0.39% Cu, and 1.5m of 58.18 g/t Au and
0.38% Cu, and Hole SAL 06-16 that returned 34.0m of 1.48% Cu and 0.22 g/t Au, including 6.0m of 5.71%
Cu and 0.1 g/t Au. Those holes will be followed up in this program.
The Drilling Plan
Cerro Blanco : Cerro Blanco is a hydrothermal alteration zone with surficial copper and gold
enrichment in rocks and soils with an underlying IP/Resistivity anomaly located in the north-eastern
quadrant of the 9,069 ha (90.69 sq km) Salvadora property with the potential to host large porphyry
style deposits. Drilling within the highly prospective Cerro Blanco zone had previously been deferred due
to challenges related to accessing the zone. The recent completion, by the Company, of a newly
constructed road greatly improves access and streamlines the costs for drilling this important target
(Figure 1 below).
Drilling at the Cerro Blanco target is scheduled to commence as soon as drill mobilization is complete.

San Lorenzo intends to drill a minimum of two holes on pads already constructed. The first two locations
will test induced polarization (“ IP”) anomalies. Importantly, the IP targets are situated below a large
area of anomalous copper and gold surface samples with many values over 1% copper and over 0.2 g/t
gold (obtained during soil and rock sampling programs previously conducted by San Lorenzo). After
completion of the first two holes, the drill program at Cerro Blanco may be expanded to include a third
hole designed to test an extension of an IP anomaly approximately 0.5 km further to the north. The
location of that third proposed hole is challenging due to terrain issues and therefore its drilling remains
contingent upon the completion of additional access work. Figure 3 below depicts the drill pad locations
together with hole directions and provides surface sample values.

Arco de Oro : Following completion of drilling on the Cerro Blanco target, San Lorenzo will continue
the drill program with two or three additional holes on the Arco de Oro trend. The Arco de Oro feature
is a trend of several epithermal vein systems trending southeast to northwest on the eastern side of the
Salvadora property (Figure 4 below).

The Arco de Oro trend features continuous “shallow surficial artisanal workings” over a strike length
exceeding 6.5 km. The historical “Alaska mine” is located within a southeast extension of the system just
south of San Lorenzo’s property boundary. The Alaska mine produced high grade material that is
reported to have averaged 14.5 g/tonne gold, 80 g/t silver and 1.5% copper to depths of approximately
5
275 metres. Flooding of the mine halted production in 1938. San Lorenzo notes that it is unable to
independently confirm the historically reported grades or depths reported above. Mid-way along the
6.5 km long trend, (in a northwest direction) is the Santa Cecilia mine which, similarly, has historically
produced material with significant grades of gold, silver and copper reported. The trend continues for
another 5 km north of the Santa Cecilia mine with artisanal workings evident all the way to San
Lorenzo’s northern property boundary. Figures 4 and 5 illustrate the historical surface workings adjacent
to the Feliz Retiro mine (Figure 5) as well as significantly south of that area (Figure 6) as well as north of
the Santa Cecilia mine (Figure 7).

Numerous IP lines previously completed by San Lorenzo crosscut the Arco de Oro trend and indicate a
large area of anomalous resistivity/chargeability readings – suggesting the possibility that a large
porphyry style system underlies the vein systems that are evident from artisanal workings at surface.
Figure 8 (below) shows the IP resistivity/chargeability area.
