A High-Revenue Project
with gross revenues totalling
$4.47B

45% of revenues, and zinc representing 35% of projected revenues. The project has an
Initial
CapEx of $388M

basi.

AgEq is calculated on a (contained metal x metal price)/ Ag price basis
This latest economic update of Cerro Las Minitas is the culmination of a number of technical
improvements of the earlier PEA, developed over the last 18 months, which together result in a
significant increase in the value of the Cerro Las Minitas asset. This includes the addition of new mineral
resources from the North Felsite zone as first reported in March 2023; the standardization of the
metallurgical recoveries and charges across each of the deposits, including the addition of gold
revenues into the project cash-flow; improvements in the mine scheduling and optimization both the
Operating and Capital costs of the project.
The updated PEA:
Increases the Life of Mine (LOM) production by
5Mt
, representing an approximate 20% increase;
Increases daily mine production capacity to
5300 tonnes per day ("tpd")
, representing an
approximate 18% increase;
Extends the mine life by
2.6yrs
;
Increases the LOM Revenue by
$765M
, representing an approximate 17% increase in revenues;
Increases the after-tax NPV5% by 45% to
$501M
; and
Similarly, increases the post-tax IRR by 3.3% to
21.2%.
Cautionary Statement
The PEA is preliminary in nature, it may include mineral resources that are considered too
speculative geologically to have the economic considerations applied to them that would enable them
to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral
resources that are not mineral reserves have not demonstrated economic viability. The mineral
resources may be affected by subsequent assessment of mining, environmental, processing,
permitting, taxation, socio-economic, and other factors.
Recommendations
The Technical Report recommends the continued development of the Cerro las Minitas project toward
pre-feasibility. Specific recommendations include:
further drilling to upgrade the classification of areas of high-value tonnes within the payback years
and to expand mineral resources;
further geotechnical assessment for mining and mineral processing (tailings) purposes;
the initiation of base-line environmental studies; and
continued social engagement with the local populations in the vicinity of the project.
The company plans to initiate a core drilling program of up to 6000m in 11 holes to test shallow targets
along the north side of the Cerro between the North Felsite and Skarn Front deposits. Drilling will start in
early September. The work is the first stage of a larger 25,000 metre exploration program on the
property with the goal of adding an additional 4 million to 8 million tonnes of mineralization to the
resource base.
About Southern Silver Exploration Corp.

discovery of world-class mineral deposits either directly or through joint-venture relationships in mineral
properties in major jurisdictions. Our specific emphasis is the 100% owned Cerro Las Minitas silver-
lead-zinc project located in the heart of Mexico's Faja de Plata, which hosts multiple world-class mineral
deposits such as Penasquito, Los Gatos, San Martin, Naica and Pitarrilla. We have assembled a team
of highly experienced technical, operational and transactional professionals to support our exploration
efforts in developing the Cerro Las Minitas project into a premier, high-grade, silver-lead-zinc mine. Our
property portfolio also includes the Oro porphyry copper-gold project and the Hermanas gold-silver vein
project where permitting applications for the conduct of a drill program is underway, both located in
southern New Mexico, USA.
