Southern Silver Intersects 10.5 metres
averaging 1,115g/t AgEq at Cerro Las Minitas
Project in Durango, México
Vancouver, British Columbia--(Newsfile Corp. - December 1, 2025) -
Southern Silver Exploration
Corp.
(TSXV: SSV) (the "Company" or "Southern Silver") reports today that rush assays from initial
drilling on the recently acquired Puro Corazon claim have returned near surface Bonanza-grade silver
mineralization from thick, semi-massive to massive-sulphide replacements in a hanging-wall lens
outside of the main skarn target.
The highlight assays were returned from hole
25CLM-203
and include:
10.5 metre interval (estimated true thickness)
averaging
560g/t Ag
, 0.1g/t Au, 0.1% Cu,
11.2% Pb
and
12.3% Zn
(1,115g/t AgEq),
including a
3.4 metre interval (estimated true
thickness)
averaging
1,067g/t Ag
, 0.2g/t Au, 0.2% Cu,
20.0% Pb
and
19.1% Zn
(
1,982g/t
AgEq
)
(1)
located within 200 metres of surface; and
two narrower, high-grade intercepts occurring several metres down hole from the highlight intercept
(above), which composite to a
2.6 metre interval (estimated true thickness)
averaging
143g/t
Ag
,
4.8% Pb
and
1.5%% Zn
(
280g/t AgEq
)
(1)
located a further 6 metres down hole.
(1)
see AgEq calculation criteria in notes to Table 1.
The replacement interval contains semi-massive to massive sulphides with up to 40% sphalerite (zinc),
30% galena (lead) and lesser pyrite with silver mineralization most strongly correlated to the galena
content and represents a carbonate replacement hosted in limestone sitting outside of the main skarn
zone and the historic Puro Corazon workings. Several additional mineralized zones were intersected
deeper in drill hole
25CLM-203
including intervals of variably mineralized skarn. The intervals have been
sampled and submitted for analyses; assays remain pending and will be released upon receipt.
In addition, step-out holes from
25CLM-203
have intersected similar replacement-style massive to semi-
massive sulphide intercepts both laterally and at depth.
These intervals have been logged and sampled,
with assays pending.
Vice President of Exploration, Rob Macdonald stated
"We're off to a strong start at Puro Corazon.
These initial bonanza-grade silver intercepts confirm the near surface, high-grade nature of the
mineralization and the overall prospectivity of the recently acquired Puro Corazon claim. With
approximately 40% of the planned drilling program completed, I expect more positive exploration
results through the first quarter of 2026."
Assays from drill hole
25CLM-202
were also received and identified mineralized skarn located adjacent
to the historic Santo Nino workings which are located to the north of the Puro Corazon claim boundary
and on the larger CLM property. Highlights include:
a
2.4 metre interval (estimated true thickness)
averaging
62g/t Ag, 3.0% Pb
and
5.2% Zn
(273g/t AgEq)
.
These are the first set of assays released from the Puro Corazon drilling program.
As of this writing, ten
of the proposed twenty-one holes are now complete for a total of 4,000 metres, with three holes currently
in progress. Approximately 12,000 metres of drilling is planned to test the Puro Corazon claim both
laterally and to depths of up to 450 metres below surface. Drilling continues on the property with less than
40% of the proposed 21-hole drill program having been completed to date, the Company anticipates
significant news flow from this current drill program through Q1 2026.

The Company also reports that it has initiated an underground sampling program in the historic Puro
Corazon workings. Up to 2000 individual channel samples are planned throughout the 13 different mine
levels of the Puro Corazon mine. The sampling will be utilized to inform updated resource models from
the mine area as well as establish potential site for future bulk-sampling of the mineralization. Sampling
has started and results will be reported as assays are received.
Next Steps
The Company is planning to incorporate the results of the Puro Corazon drilling program into the much
larger Cerro Las Minitas project to significantly enhance the project economics. Final assays are
expected to be received by the end of the first quarter of 2026, after which the Company intends to:
update the Mineral Resource Estimate of the Cerro Las Minitas project; followed by
an update of the Preliminary economic Assessment ("PEA") of the project in accordance with the
provisions of National Instrument 43-101.
The Company reports that work on the Cerro Las Minitas project continues advancing numerous upside
opportunities identified subsequent to the July 2024 PEA, while also derisking and advancing the project
with the commencement of baseline data collection, hydrology, geotechnical, archaeological and land
surveys and studies.
As currently modelled, the Cerro Las Minitas project features a large-scale underground mining
operation with robust project economics and high gross revenues in a well located and mining friendly
jurisdiction in southeast Durango, Mexico. For more information on the details of the current economic
assessment of the Cerro Las Minitas project please refer to Southern Silver's news release dated June
10, 2024.
