Vancouver, British Columbia--(Newsfile Corp. - September 21, 2026) - Southern Silver Exploration Corp. (TSXV: SSV) (the "Company" or "Southern Silver") reports assays from the first five holes of the definition drill program on the Puro Corazon target which provide better resolution to the distribution of the strongly silver enriched polymetallic mineralization.
Highlight assays include:
a 35.0 metre interval averaging 188g/t Ag, 0.3%g/t Cu, 4.9% Pb and 4.6% Zn (399g/t AgEq), including a 9.4 metre interval averaging 344g/t Ag, 0.2% Cu, 9.1% Pb and 6.7% Zn (665g/t AgEq)(1) from drillhole 26CLM-225;
a 5.2 metre interval averaging 277g/t Ag, 0.1% Cu, 9.9% Pb and 6.3% Zn (598g/t AgEq), including a 3.6 metre interval averaging 384g/t Ag, 0.1% Cu, 13.4% Pb and 8.3% Zn (812g/t AgEq)(1) from drillhole 26CLM-226; and
a 5.3 metre interval averaging 493g/t Ag, 0.3% Cu, 10.2% Pb and 7.2% Zn (850g/t AgEq) from drillhole 26CLM-227.
(1) see AgEq calculation criteria in notes to Table 1. Intervals are reported as estimated true thickness unless otherwise indicated
These initial results are from the ongoing 14,000 metre core hole drill program that was started in June '26 and is designed to upgrade resource classification in the Puro Corazon target. The current drill program will test an area that is roughly a 200 metres strike-length by 300 metres down dip within the Puro Corazon claim. The above reported drill holes successfully targeted the upper part of the zone with nominal 40 metre step-outs from previously reported intercepts that include 10.5 metres averaging 1,115g/t AgEq (see News Release dated December 1, 2025) from 25CLM-203 and 10.4 metres averaging 743g/t AgEq (see News Release dated January 6, 2026) from 25CLM-205 as well as other mineralized intercepts.
Both skarn and replacement styles of mineralization are identified in these holes with several intercepts, located well outboard of the Skarn zone, correlating with previous identified mineralization in the El Sol structural zone and the main skarn target.
Vice President of Exploration, Rob Macdonald, stated, "This is a very solid start to the definition drill program on the Cerro Las Minitas project. These initial step out holes not only help confirm the previously reported thicknesses and grades of mineralization in this target area, but provide better definition as to the projection of several of the mineralized zones. Drilling continues on the project and the Company anticipates good news flow over the coming weeks and months."
The Company reports that drilling continues with eight of 30 planned holes having been completed to date with one hole in progress. Logging and sampling continue and assays from three holes are pending.

Next Steps
Work continues to incorporate results from the earlier 2025-26 Puro Corazon drilling into the larger Cerro Las Minitas project which is expected to enhance the project economics and the scalability of the mine plan. Work 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.

1) Analyzed by FA/AA for gold and ICP-AES by ALS Laboratories, North Vancouver, BC. Silver (>100ppm), copper, lead and zinc (>1%) overlimits assayed by ore grade ICP analysis.
2) High silver overlimits (>1500g/t Ag) and gold overlimits (>10g/t Au) re-assayed with FA-Grav. High Pb (>20%) and Zn (>30%) overlimits assayed by titration. AgEq and ZnEq were calculated using prices of $3,200/oz Au, $38/oz Ag, $4.75/lb Cu, $0.95/lb Pb and $1.35/lb Zn.
3) AgEq and ZnEq calculations utilized relative metallurgical recoveries of Au 48.6%, Ag 93%, Cu 70%, Pb 87% and Zn 93%.
4) Composites are calculated using a 80g/t AgEq cut-off in sulphide and 0.5g/t AuEq in the oxide gold zone. Composites have <20% internal dilution, except where noted; anomalous intercepts are calculated using a 10g/t AgEq cut-off.
