VANCOUVER, British Columbia, March 26, 2026 (GLOBE NEWSWIRE) — Zacatecas Silver Corp. (TSXV: ZAC | OTCQB: ZCTSF | FRA: 7TV) (“Zacatecas Silver” or the “Company”) is happy to announce that it has obtained assay outcomes for 124 rock-chip seize samples taken from waste dumps round 11 shallow historic shafts at El Cristo. Twenty-nine samples assayed above 100 g/t silver equal (“Ag Eq”) with a peak assay of 670 g/t Ag Eq.
Highlights of the Sampling Program:
Eighty samples collected from waste dumps surrounding eight shallow historic shafts from a number of veins alongside roughly 1.2 km of strike.Peak assay of 670 g/t Ag Eq from a pattern which assayed 0.06 g/t Au, 659 g/t Ag, 0.011 % Pb and 0.3 % Zn.Peak gold assay of two.41 g/t, peak silver assay of 659 g/t, peak copper assay of 0.058%, a number of lead assays above 1% (lead not assayed for over-range) and peak zinc assay 4.97%.
The shafts are located alongside the strike extent of the El Cristo vein system, in shut proximity to deliberate diamond drill areas. Assay outcomes verify the presence of near-surface silver and base steel mineralization related to an intermediate sulphidation system. These outcomes ought to be interpreted within the context of shaft dump sampling, as a number of shafts solely intersected the higher oxidized parts of the veins, and the fabric current on the dumps was traditionally thought-about waste by prior operators.
Regardless of these limitations, the assay information has offered priceless enter for drill focusing on by delineating areas the place sulphide mineralization happens close to floor. Vein textures and sulphide geochemistry, characterised by gold, silver, lead, zinc, and minor copper, are in step with the higher ranges of silver-dominant, intermediate sulphidation vein programs.

Whereas such programs are usually mineralized over vertical extents of 500 to 800+ metres, the Firm’s preliminary drill program will concentrate on testing shallow depth extensions of the veins.

Administration Commentary
Chief Geologist and Director, Dr. Chris Wilson, commented:
“The results of the dump sampling program have demonstrated high silver and silver equivalent grades from multiple veins over a strike length of approximately 1.5 km. The assay results are especially significant, given rock chip samples were taken from dumps around the shallow historical shafts, and was material considered low grade by the historical miners. Moreover, a number of samples were extensively oxidised and leached.”

Analytical Strategies and QA/QC
Rock chip samples have been collected and bagged beneath the supervision of Firm personnel following commonplace business practices. Samples have been submitted to ALS Zacatecas for evaluation. Samples have been ready by drying, sieving and pulverizing, and analyzed for Ag and a collection of parts by multi-element ICP strategies following four-acid digestion. The Firm inserted licensed reference supplies, blanks and area duplicates into the pattern stream to observe analytical high quality.
