SAN LORENZO BEGINS KEY PHASE OF EXPLORATION WITH INDUCED

POLARIZATION SURVEY COMMENCING ON IT’S 100% OWNED LARGE SCALE

COPPER- GOLD PORPHYRY SALVADORA PROJECT, CHILE

Calgary, Alberta, September 8, 2021: San Lorenzo Gold Corp. (" San Lorenzo " or the

"Company") (TSXV - SLG) announces that a key phase of exploration has commenced on its

100% owned Salvadora Copper – Gold Project (“Salvadora”) located in Chile. The Company is

conducting an Induced Polarization (“IP”) survey consisting of approximately 86 line kilometres

and will follow up on positive results from previous limited IP surveys conducted by the

Company. The 100% owned Salvadora Project is 8,796 hectares and is geologically situated in

one of the productive copper belts in Chile and is approximately 15 km from the world class El

Salvador open pit copper-gold mine (see Figure 2).

The IP survey will initially cover the central portion (“CMZ Zone”) of the Property which hosts

favourable porphyry style mineralization and phyllic to potassic alteration containing

disseminated and vein hosted copper mineralization identified by surface sampling and limited

diamond drilling (see Figure 1).

IP is a key survey for identifying porphyry style copper mineralization and results from the IP

survey combined with data from the Company’s recently completed Magnetometer survey (see

News Release dated July 22, 2021) will be used to prioritize diamond drill targets in a large

diamond drill programme on what is one of Chile’s most prospective large scale copper – gold

porphyry systems.

Salvadora Copper – Gold Project Highlights

 Potential to discover large bulk mineable copper – gold porphyry

 15 km from world class billion + tonne El Salvador copper – gold porphyry mine

o Recently announced US$1.4 billion expansion to increase annual copper

production to 200 million pounds

 Geologically very similar to El Salvador mine including:

o Style of mineralization;

o Alteration;

o Favourable copper bearing rocks are similar age;

 Project has not been fully and systematically explored leaving potential untapped;

o Limited diamond drilling;

o Magnetometer survey recently completed;

 Drilling in the porphyry style alteration zones has returned encouraging copper – gold

grades;

o 156 metres of 0.28% copper and 0.08 g/t gold

o 35 metres of 0.28% copper and 0.11 g/t gold;

 Additional upside from two extensive epithermal vein systems ;

o Outcrop and underground sampling returned:

 5.1 - 154.5 g/t gold, 1.3 - 61.8 g/t silver and 0.16 - 1.75% copper over

1.5–2.1 metres;

o Historically reported small scale, underground production to 240 metres:

 4.5 – 195 g/t gold, 20 – 356 g/t silver ,1.4 – 23.6% copper over 0.5 -3.0

metres

 Located at relatively low elevation and readily accessible year round.
