Zacatecas Silver Corp. Completes Surface Sampling and Mapping Program at Oso Negro Project Zacatecas Silver Corp. completed its initial rock-chip sampling program at the Oso Negro project, located in Sonora, Mexico. The program was completed in March 2026 over the course of five days and samples have been dispatched to ALS for analysis with an expected turn-around of four to six weeks. One hundred and fifty-six rock-chip grab samples were taken from 3 out-cropping low sulphidation veins with cumulative strike length of over 2 km. Veins are up to 3 m wide, multiphase with common veins breccias and pervasive iron oxides after sulphides. Quartz and vein textures are typical of the uppermost levels of a low sulphidation system, indicating that if present, the boiling and thus precious metal mineralization will be preserved below. All rock chip samples were cut prior to submission to ALS and a reference sample retained. Cut slabs show that veins are highly brecciated veins, with abundant limonite and hematite after sulphides, and dark grey goethite a secondary precipitate in fractures. The presence of these iron oxides is consistent with oxidation of sulphides. Silicified fragments of wall-rock and vein are locally pervasively altered to limonite. Quartz is typically chalcedonic to finely saccharoidal consistent, with local bladed pseudomorphs, indicative of deposition above the boiling zone. Quartz may be locally dark grey and sulphidic. Secondary silver minerals were noted in some samples. The rock chip sampling has demonstrated a robust low sulphidation vein system, characterized by over two strike kilometers of multiphase, brecciated, iron-oxide stained and infilled, upper level veins. Oso Negro represents a high-priority, undrilled exploration target within a historic mining district known for high-grade precious metal mineralization. Historical channel sampling completed by previous operators returned significant grades, including 5.15 g/t Au and 953 g/t Ag over 1.2 metres, and 2.55 g/t Au and 346 g/t Ag over 1.8 metres, highlighting the strength and consistency of mineralization along strike.

Zacatecas Silver Corp Announces Drilling Commencement And Completion Of First Hole At El Cristo Zacatecas Silver Corp. announced the commencement of its 2026 diamond drilling program at the El Cristo Project, located within the 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. 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 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. The technical information in this news release has been reviewed and approved by Chris Wilson, B.Sc. (Hons), PhD, FAusIMM (CP), FSEG, FGS, Chief Geologist of Zacatecas Silver. Dr. Wilson is a Qualified Person as defined by NI 43-101 and is not independent due being Chief Geologist and a Director. Announcement • Mar 27
Zacatecas Silver Announces Results from Rock Chip Sampling Program At El Cristo Zacatecas Silver Corp. announced that it has received assay results for 124 rock-chip grab samples taken from waste dumps around 11 shallow historical shafts at El Cristo. Twenty-nine samples assayed above 100 g/t silver equivalent (“Ag Eq”) with a peak assay of 670 g/t Ag Eq. Eighty samples collected from waste dumps surrounding eight shallow historical shafts from multiple veins along approximately 1.2 km of strike. Peak assay of 670 g/t Ag Eq from a sample which assayed 0.06 g/t Au, 659 g/t Ag, 0.011 % Pb and 0.3 % Zn. Peak gold assay of 2.41 g/t, peak silver assay of 659 g/t, peak copper assay of 0.058%, multiple lead assays above 1% (lead not assayed for over-range) and peak zinc assay 4.97%. The shafts are situated along the strike extent of the El Cristo vein system, in close proximity to planned diamond drill locations. Assay results confirm the presence of near-surface silver and base metal mineralization associated with an intermediate sulphidation system. These results should be interpreted in the context of shaft dump sampling, as several shafts only intersected the upper oxidized portions of the veins, and the material present on the dumps was historically considered waste by prior operators. Despite these limitations, the assay data has provided valuable input for drill targeting by delineating areas where sulphide mineralization occurs near surface. Vein textures and sulphide geochemistry, characterized by gold, silver, lead, zinc, and minor copper, are consistent with the upper levels of silver-dominant, intermediate sulphidation vein systems. While such systems are typically mineralized over vertical extents of 500 to 800+ metres, the Company’s initial drill program will focus on testing shallow depth extensions of the veins.

Zacatecas Silver Corp. Provides Corporate Update for 2026 and Highlights Upcoming Drill Program At Silver Project Zacatecas Silver Corp. provided shareholders with a corporate update outlining key operational progress across its portfolio and highlighting recent regulatory developments in Mexico that materially enhance the outlook for the Company's assets - particularly its Esperanza Gold Project. 2025 was a year of revitalization, positioning the Company for a catalyst-driven 2026. Key accomplishments include: Successful rebranding of the Company's corporate profile, including a refreshed website and investor presentation, better reflecting the scale, quality, and growth potential of the portfolio. Finalization of the upcoming drill program at the Zacatecas Silver Project, positioning the Company to resume active exploration and value creation. Preservation of strategic optionality across the portfolio, maintaining flexibility to advance, expand, or unlock value from assets as market and permitting conditions continue to improve. Completion of strategic financings, strengthening the balance sheet and positioning the Company for active exploration and portfolio advancement. Current Portfolio Overview: Zacatecas Silver controls a high-quality, resource-backed portfolio anchored by two advanced Mexican assets, providing meaningful leverage to silver and gold in a strengthening commodity and permitting environment. Zacatecas Silver Project - Zacatecas State, Mexico: Inferred mineral resource of 20.5 million ounces of silver equivalent ("AgEq") (19.0 million ounces of silver ("Ag") and 19.2 thousand ounces of gold ("Au")) from 3.41 million tonnes at 187 g/t Ag Eq (173 g/t Ag and 0.18 g/t Au) at the Panuco vein system. Located in one of Mexico's most prolific historic silver districts; Multiple vein systems with demonstrated high-grade continuity; Permitted for drilling, with a near-term drill program designed to expand known resources and test priority targets. This approval represents the first new open-pit mining permit issued in Mexico since 2020, marking a notable shift in the regulatory environment following several years of uncertainty. For much of the past five years, the market broadly assumed that permitting new open-pit mines in Mexico was effectively unattainable, leading to valuation discounts for companies with open-pittable development assets. At the Company's flagship Zacatecas Silver Project, management has remained focused on execution and de-risking in advance of drilling. Recent milestones include: Execution of a 4,000-metre diamond drill contract with Major Drilling, a leading international drilling contractor; Unanimous approval and execution of a new community access agreement with the Ejido Panuco, providing secure access for drilling and future exploration; Finalization of surface access agreements with private landowners at El Cristo, providing district-wide flexibility to establish drill pads across priority targets. These achievements position the Company to commence its upcoming drill program once final administrative steps are completed and further demonstrate Zacatecas Silver's strong track record of community engagement--an increasingly critical success factor for exploration and development in Mexico. The initial 4,000-metre drill program is designed to test high-priority targets along the Panuco and El Cristo vein systems, with flexibility to expand the program should results warrant, supported by the Company's strengthened treasury. The deposit offers optionality across mining and recovery scenarios and the ability to develop in a staged manner, thereby optimizing payback, and is among the highest-grade heap-leach deposits globally." Positioning for 2026 and Beyond As the Company looks ahead, its priorities include: Receiving final approvals and commencing the 4,000- Metre drill program at the ZacateCas Silver Project, with flexibility to expand based on results; Continuing to strengthen community relationships and surface access across the district; Advancing strategic discussions and evaluation for the optimal path forward for Esperanza under the improving regulatory environment; Expanding investor outreach, particularly to groups seeking silver leverage and credible open-pit gold optionality in Mexico; Continuing to advance targeted opportunities to strengthen and optimize the Company's project portfolio; Assess the potential to re-model and optimize the Company's current exploration and portfolio.
