San Lorenzo GOLD Exploration Update High Priority Target 2 at Salvadora – Tres Amigos

Exploration Programs

SAN LORENZO GOLD EXPLORATION UPDATE

HIGH PRIORITY TARGET 2 AT SALVADORA – TRES AMIGOS

CALGARY, AB / March 19, 2024 / San Lorenzo Gold Corp. (TSXV: SLG) (“San Lorenzo” or

“the Company”) is pleased to provide additional information on the Tres Amigos target located

on its flagship Salvadora Property.

San Lorenzo has identified six individual targets on Salvadora. Two of them – Tres Amigos and

Cerro Blanco – are the highest priority targets for additional exploration efforts to commence

immediately. San Lorenzo’s most recent press release (Feb 26, 2024) pertained to the Cerro

Blanco target. This press release pertains to the Tres Amigos target.

San Lorenzo believes that incremental spending on the aforementioned two targets has the

greatest potential to impact near-term valuation.

The Tres Amigos Target

The Tres Amigos Target area is characterised by multiple epithermal vein systems close to

surface. The known vein system extends for 2.5 km with widths up to 200 meters – as evident

from numerous surface artisanal workings and high-grade Cu-Au rich outcrops at surface. Since

2015, San Lorenzo has completed initial phases of exploration on the system including surface

soil and rock sampling, limited IP and shallow depth confirmatory drilling. Management believes

that Tres Amigos hosts a mineralized system that has a combination of scale and grade

that may allow San Lorenzo to build a significant high-grade copper/gold resource.

Surface and Mine Face Sampling

Surface soil geochemical sampling has shown that the whole Tres Amigos target area exhibits

strong anomalous copper values - greater than 300 ppm within which two 1 – 1.5 sq km areas

average 0.2 - 0.28% Cu in soils. Mineralized outcrop and float samples from the two sectors

returned values of 0.3 – 5.6% Cu and anomalous gold values from 0.174 – 4.14 g/t Au.

Figure 1 below provides an outline of the expanded Tres Amigos target area including rock chip

sample values. It also identifies the Tres Amigos and Sin Codicia mine locations and the

location of the holes drilled by San Lorenzo during the 2016 and 2018 programs. It also

provides the grades obtained from mineralized intercepts in those drill programs.

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

SAL-01-18 59 109 60 0.47 0.17

Including 75 107 33 1.07 0.37

SAL-02-18 15 40 25 1.04 0.25

including 30 38 8 1.58 0.47

SAL-06-16 36 70 34 1.48 0.22

including 48 54 6 5.71 0.1

Prior Drilling

With widths of up to 200 meters evident on Tres Amigos from historical workings, the two limited

drilling programs completed to date have so far confirmed mineralized widths below surface of

up to 60 meters in the high-grade copper-gold-silver rich epithermal vein system (grades of 0.47

– 5.71 % Cu, 0.17 – 0.25 g/t Au and 3.1 - 26.9 g/t Ag were obtained). That drilling, at less than

100 meter depths, only tested upper oxide material such that the system remains open at depth.

Results to date support management’s opinion that additional exploration, including drilling

along the additional width, strike, and depth of the system has the potential to define a many-

million-ton bulk mineable deposit within the Tres Amigos target.

Prior Workings

As recently as 2006, mining in the Tres Amigos target occurred from a spiral decline from which

high grade oxide ore - up to 14% Cu - was extracted – from a mine known as the “La Fortuna”.

Reported grades have been supported by mine face sampling conducted by San Lorenzo which

showed copper grades of 2.5 – 14.75% copper across 1.8 – 4.1 meter widths.

Figure 2: shows the decline entrance on the La

Fortuna mine from which up to 14% copper material

was historically mined.

Figure 3 above highlights the extent of the existing IP/Resistivity lines (in blue) and the

locations of the planned additional lines (in yellow).

Immediate Next Steps - IP

San Lorenzo intends to immediately acquire the additional IP coverage by completing the

(yellow) lines outlined above. San Lorenzo is hopeful that the additional coverage will identify

anomalies in the larger northern and northwestern sector of the Tres Amigos Target underlying

the areas of numerous high Cu-Au rich surface samples. IP will provide deeper penetration that

should highlight zones of copper-rich sulphides beneath near surface oxides.

Follow-Up Next Steps - Drilling

San Lorenzo expects to commence a drilling program on both the Tres Amigos and the Cerro

Blanco target areas during Q3 2024. While the locations on the Cerro Blanco target have

largely been decided upon, the location of drill holes on the Tres Amigos target remains

dependent on the results of the upcoming IP program.

The Salvadora Property Generally

Significant surface soil and rock samples that are highly anomalous in copper and gold, together

with the significant grades obtained by San Lorenzo from drilling on the Tres Amigos target (and

on the nearby Arco de Oro and Caballo Muerto targets) continues to affirm to management of

San Lorenzo the existence of several hydrothermal systems that have mineralized the

Salvadora property. This observation is further supported by the numerous artisanal workings

evident on the Salvadora property.

Figure 4 above illustrates the artisanal workings – depicted by mine symbols - that are evident

on the Salvadora property. Each indicates NW-SE trends - the one circled in red being on Tres

Amigos target and the one circled in blue being on Arco de Oro target.

The Arco de Oro Target – Further Details to be Provided Within Approximately 2 Weeks

The Arco de Oro target is a third high value target within the Salvadora property that San

Lorenzo will provide more detailed information on in the coming weeks. Further exploration at

Arco de Oro is being delayed until completion of next steps on Tres Amigos and Cerro Blanco.

About San Lorenzo Gold Corp.

San Lorenzo Gold is involved in the exploration and advancement of mineral properties in the

Mega Porphyry Cu-Au and the coastal IOCG belts of Chile. The Salvadora property is located in

the Mega Porphyry Cu-Au belt and is being explored for large scale copper-gold porphyry

deposits and high-grade epithermal gold-silver-copper vein type deposits.

The Company has two other properties: Nancagua, a high grade mesothermal gold-silver

prospect and Punta Alta, a copper-gold-silver-cobalt prospect with related disseminated and

vein style copper-gold-silver-cobalt mineralization in the coastal IOCG belt.
