Southern Silver Reports 2.8m of 665g/t AgEq and 4.0m of 367g/t AgEq from Underground Channel Sampling at the Puro Corazon Mine

Southern Silver reports high-grade channel sample, but only one intercept disclosed.

What the company is saying

Southern Silver Exploration Corp. is highlighting new assay results from underground channel sampling at the Puro Corazon Mine on the Cerro Las Minitas property. The company singles out a 2.3 metre interval averaging 313g/t silver, 0.1% copper, 5.4% lead, and 4.7% zinc, equating to 554g/t silver equivalent. The announcement is tightly focused on this single result, with no broader context or claims about deposit size, continuity, or economic potential. The language is factual and avoids promotional tone, simply stating the assay values. There are no forward-looking statements or projections. No mention is made of additional results, resource estimation, or next steps.

What the data suggests

The only quantitative disclosure is a single channel sample: 2.3 metres grading 313g/t silver, 0.1% copper, 5.4% lead, and 4.7% zinc, for a calculated 554g/t silver equivalent. This is a high-grade intercept over a short width, consistent with potentially economic mineralisation if continuity and scale are demonstrated. No information is provided about the number of samples taken, their spatial distribution, or whether this result is representative. The absence of other assay data or geological context limits assessment of the broader system. No resource estimate, tonnage, or grade distribution is disclosed. The data is specific but extremely limited in scope, offering no insight into project scale or development potential.

Analysis

The announcement is a factual disclosure of new assay results from underground channel sampling, with specific grades and widths reported. There are no forward-looking statements, projections, or aspirational claims about future resource size, production, or economic outcomes. The language is proportionate to the evidence, simply reporting the technical results without embellishment. No capital outlay or development plans are mentioned, and there is no attempt to frame the results as transformative or to imply imminent value creation. As this is a standard exploration-stage update with no exaggerated claims or promotional tone, the gap between narrative and evidence is negligible. The data supports only what is stated: a specific assay result.

Risk flags

• ●Reliance on a single highlight assay introduces sampling bias risk, as one high-grade interval may not reflect the overall tenor or continuity of mineralisation. Without additional results or geological context, investors cannot assess whether this intercept is exceptional or typical.
• ●The absence of resource estimates, tonnage, or broader sampling data means there is no basis for evaluating the scale or economic viability of the project. This limits the ability to gauge potential upside or downside.
• ●No forward-looking guidance or planned next steps are disclosed, creating uncertainty about the company's exploration strategy, funding requirements, and timeline for advancing the project.

Bottom line

This announcement provides a single high-grade channel sample from the Puro Corazon Mine, but offers no broader geological or economic context. The result is technically impressive on its own, yet without supporting data or information about continuity, it cannot be extrapolated to project value or scale. The company's narrative is restrained and factual, avoiding hype, but the lack of additional assays or stated plans leaves investors with little actionable information. For this update to become investment-relevant, Southern Silver would need to disclose a series of results, resource estimates, or a clear exploration roadmap. The key takeaway is that while the reported grade is strong, its significance remains indeterminate without further data.

Announcement summary

(TSXV: SSV) Southern Silver Exploration Corp. reports additional assays from underground channel sampling at the Puro Corazon Mine on the Cerro Las Minitas property, with highlight assays including: 2.3 metres averaging 313g/t Ag, 0.1% Cu, 5.4% Pb and 4.7% Zn (554g/t AgEq); 2.8 metres averaging 289g/t Ag, 0.2% Cu, 9.6% Pb and 6.6% Zn (665g/t AgEq); 1.2 metres averaging 1057g/t Ag, 21.0% Pb and 21.6% Zn (2042g/t AgEq); and 4.0 metres averaging 198g/t Ag, 6.0% Pb and 1.9% Zn (367g/t AgEq). A total of 230 channels comprising 1,380 individual samples were collected, with sample intervals ranging from 0.15m to 2.0m, most in the 0.5m to 1.0m range, and channel samples spaced every 3.0 meters. The Puro Corazon Mine currently comprises a partially completed spiral decline (Rampa Guadalupe) and 14 mining levels which extend 220 metres below surface, and has been operated intermittently on a small scale (~50-80tpd) since the 1980s. Six core holes totaling 2,194 metres have been completed to date in the Phase I definition drill program, which commenced in June 2026, with assays pending. The company is incorporating the results of the recently completed Puro Corazon drilling and underground sampling programs into the larger Cerro Las Minitas project, which is expected to significantly enhance both the project economics and mine plan. Over the coming months, the company intends to continue a Phase I definition drill program of up to 14,000 metres, update the Mineral Resource Estimate of the Cerro Las Minitas project, and follow with an update of the Preliminary Economic Assessment ("PEA") of the project. Additional work includes an underground Lidar survey of the workings (completed earlier this year), geotechnical surveys, and further hydrological characterization of the area around the Puro Corazon target (in progress). The Cerro Las Minitas project is currently modelled as a large-scale underground mining operation with robust project economics and high gross revenues in southeast Durango, Mexico.
