Zacatecas Silver Corp. (TSXV: ZAC,OTC:ZCTSF | OTCQB: ZCTSF | FRA: 7TV) ("Zacatecas Silver" or the "Company") is pleased to announce the commencement of its 2026 diamond drilling program at the El Cristo Project, located within the prolific Zacatecas Mining District, Mexico. The first hole was collared by Major Drilling Mexico on the 27th of March and completed on the 30th of March.
The first diamond drill hole was drilled to a downhole depth of 117 m at an inclination of -60° to target the near-surface downdip extension of an intermediate sulphidation vein. A brecciated and mineralized structure was intercepted between 89 and 108 m downhole.
Eric Vanderleeuw, CEO and Director of Zacatecas Silver commented, "Intersecting the vein system with visible sulphides in our very first hole is exactly what we were aiming for, the presence of galena and sphalerite confirms we are in a fertile, mineralized system with clear potential for high-grade silver. This is an outstanding start, and we are eager to build on this momentum as the drill program progresses."
Figure 1: A 3 m run of PQ core from 90 m downhole depth displaying typical mineralization. Note pervasively silicified, fractured andesite and basalt, with abundant pyrite, galena, and sphalerite, along with multiphase quartz veining and brecciation.
Mineralization is associated with multiphase and brecciated quartz veins and is hosted in a highly fractured and strongly silicified andesitic and basaltic volcanoclastic sequence. Very fine dark-grey sulphide is pervasive, and clotted sphalerite and galena, with traces of chalcopyrite, are developed throughout this zone. Vein textures and mineralogy are consistent with the uppermost parts of silver-base metal mineralized intermediate sulphidation epithermal veins within the district. Analysis of rock chip samples from the dumps around artisanal shafts at El Cristo (see News Release dated March 26, 2026) shows a strong association between high-grade silver assays and galena and sphalerite.
The company is currently sampling this hole and expects to deliver samples to ALS in Zacatecas by Thursday of this week.
About Zacatecas Silver Corp.
The Company has two key projects: the Zacatecas Silver Project in Zacatecas State, Mexico, and The Esperanza Gold Project in Morelos State, Mexico.
The Zacatecas Silver Project is located in Zacatecas state, Mexico, within the highly prospective Fresnillo silver belt, which has produced over 6.2 billion ounces of silver. The Company holds 7,826 hectares (19,338 acres) of ground that is highly prospective for low-sulphidation and intermediate-sulphidation silver base metal mineralization and potentially low-sulphidation gold-dominant mineralization. The Company announced an increase in silver resource at the Panuco South and North underground Mineral Resource Estimate now consisting of 3.41 million tonnes at 187 g/t AgEq (173 g/t Ag and 0.18 g/t Au) for 20.5 million ounces AgEq (19.0 million ounces silver and 19.2 thousand ounces gold) (see news release dated May 31, 2023).
The silver property is 25 kilometres (km) southeast of MAG Silver Corp.'s Juanicipio Mine and Fresnillo PLC's Fresnillo Mine. The Property shares common boundaries with former Pan American Silver Corp., now Defiance Silver claims and El Orito, which is owned by Endeavour Silver.
Esperanza is an advanced stage, attractive low-cost, low-capital-intensity and low-technical-risk growth project located in Morelos state, Mexico. Alamos has progressed the project through advanced engineering, including metallurgical work, while also focusing on stakeholder engagement, including building community relations. The Company announced a Mineral Resource Estimate at Esperanza consisting of a Measured and Indicated Mineral Resource Estimate of 30.5 million tonnes at 0.97 g/t AuEq for 956 thousand ounces AuEq and an Inferred Mineral Resource estimate of 8.7 million tonnes at 0.98 g/t AuEq for 277 thousand ounces AuEq (see news release dated November 16, 2022).
