VANCOUVER, British Columbia, July 14, 2026 (GLOBE NEWSWIRE) -- Zacatecas Silver Corp. (TSXV: ZAC | OTCQB: ZCTSF | FRA: 7TV) ("Zacatecas Silver" or the "Company") is pleased to announce a non-brokered private placement of up to $2,500,000 (the "Offering"). Proceeds will be used to fund the Company's planned maiden drill program at the Oso Negro project in Sonora, Mexico, following the recent completion of Phase Two rock-chip sampling and vein mapping (see news release dated July 9, 2026), together with continued exploration across the Company's six-project Mexican portfolio and general working capital.
Highlights:
Non-brokered private placement of units for gross proceeds of up to $2,500,000.
Proceeds earmarked to fund the maiden diamond drill program at Oso Negro, Sonora, pending receipt of a SEMARNAT drill permit, plus continued portfolio-wide exploration and working capital.
Oso Negro hosts the Prospecto (2.5 km strike) and Tere (0.5 km strike) low sulphidation epithermal vein systems, with phase one sampling returning up to 14.8 g/t Au and 2,340 g/t Ag (see news releases dated June 9, 2026 and July 9, 2026).
20 drill pad locations identified at Oso Negro; ecological studies complete and drill permit application in progress.
Oso Negro: An Emerging, Untested High-Grade System
The Oso Negro project, located in Sonora, Mexico, is an undrilled, high-grade low sulphidation epithermal system controlled by the Prospecto and Tere veins. Phase two geological mapping and sampling, completed in the first week of July 2026, extended the mapped strike length of the Prospecto vein system to over 2.5 kilometres and the Tere vein to approximately 0.5 kilometres. Three hundred and ninety-one rock-chip grab samples were collected during phase two to refine the position of planned angled diamond drill targets, building on phase one results of up to 14.8 g/t Au and 2,340 g/t Ag across 156 samples.
The Company has identified 20 drill pad locations at Oso Negro and completed the ecological studies required to apply to SEMARNAT for a drill permit. Vein textures observed to date are consistent with the uppermost levels of a low sulphidation epithermal system, where precious metal mineralization is typically preserved in association with a boiling zone at depth — indicating that the highest-grade portion of the system remains untested below current sampling depths.
Eric Vanderleeuw, CEO & Director, commented: "Oso Negro has all the hallmarks of a high-grade epithermal discovery we want to be drilling — strong grades at surface, over three kilometres of combined mapped vein strike, and geology consistent with a boiling zone at depth that remains untested by drilling. Our Phase Two work confirmed extensive sulphidic quartz veining across both the Prospecto and Tere systems and has provided a clear roadmap for drill targeting. This financing positions us to launch our maiden drill program at Oso Negro while continuing to advance our broader portfolio of highly prospective Mexican assets."
