Zacatecas Silver Corp. announced an increase to its Inferred silver Mineral Resource Estimate at the Panuco South and North Deposits within the Zacatecas Property. The Updated Mineral Resource Estimate was prepared by P&E Mining Consultants Inc. ("P&E") for Zacatecas Silver.

P&E prepared the initial Inferred Mineral Resource Estimate that was a disclosed in the Technical Report dated January 28, 2022 titled "Independent NI 43-101 Technical Report, Zacatecas Properties, Zacatecas State, Mexico," filed on SEDAR on January 28, 2022. Mineral Resource Estimate Assumptions: The Mineral Resource Estimate was generated using inverse distance cubed for gold and silver for grade interpolation within a 3-D block model, constrained by mineralized zones defined by wireframes solid models. The bulk density value of 2.8 t/m3 used in the Mineral Resource Estimate were derived from a regression equation based on data measured from samples collected from re-assayed drill core completed by Zacatecas Silver.

The database for the Mineral Resource Estimate consisted of 138 drill holes totaling 30,684 m, and 183 trenches totaling 4,540 m, of which a total of 108 drill holes totaling 22,467 m and 113 trenches totaling 3,000 m intersected the mineralization wireframes used for the Mineral Resource Estimate. The drill hole database contained assays for silver and gold as well as other metals of no economic importance. Zacatacas Silver's seasoned exploration team carried out extensive data verification on the historical database by re-sampling 178 historical sample intervals, which added to the 243 new mineralized samples making a total of approximately 50% verified constrained sample intervals in the Mineral Resource Estimate.
