Zacatecas Silver Corp. is pleased to announce its initial Mineral Resource Estimate (“MRE”) at the Esperanza Gold Project. The MRE was prepared by P&E Mining Consultants Inc. (“P&E”) on behalf of the Company.
Highlights:
The Esperanza Mineral Resource Estimate consists of:
Dr. Chris Wilson, Chief Operating Officer and a Director of Zacatecas comments, “This Mineral Resource Estimate of 956 thousand Measured and Indicated gold equivalent ounces and 276 thousand Inferred gold equivalent ounces will provide a strong fundamental foundation for the Preliminary Feasibility Study (“PFS”) now underway at Esperanza. With this initial high grade Mineral Resource Estimate complete, we can focus on the completion of this PFS which will evaluate economics targeting a low capex, low cost and high margin operation that can generate substantial stakeholder benefit including economic, employment, environmental and revenue opportunities for the surrounding communities.“
Re-logging of historical drill core by the Company, in conjunction with Mineral Resource modelling by P&E, has confirmed that high-grade mineralization extends down the western limb of the feldspar porphyry intrusion that sits below the skarn mineralization. This interpretation suggests that metal-rich mineralizing fluids were sourced from a deeper intrusion to the west which is yet to be drilled. Robust gold-silver target types include disseminated, skarn and replacement types in carbonate sediments, and sheeted and stockwork veins within the upper carapace of the mineralizing intrusion.

Notes: |
|
|
(1) |
Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. |
|
(2) |
The estimate of Mineral Resources may be materially affected by environmental permitting, legal title, taxation, socio-political, marketing or other relevant issues. |
|
(3) |
Resources are classified according to Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards (2014) and CIM Best Practices (2019); |
|
(4) |
The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration. |
|
(5) |
Gold equivalent Mineral Resources for the Esperanza Gold Project were calculated using the following metal prices: Au at US $1,700 and Ag at US $22/oz. |
|
(6) |
Metallurgical recoveries have been estimated to be 70% gold and 25% silver. |
|
(7) |
The Mineral Resource Estimate uses a cut-off of 0.2 g/t AuEq for Pit-Constrained and 1.2 g/t AuEq for Out-of-Pit based on US$/tonne costs of $2.50/mining, $6.50 processing and $1.25 G&A. |
|
(8) |
AuEq = Au g/t + (Ag g/t x 0.005) |
|
(9) |
Out-of-pit MRE blocks were reviewed for grade and geometric continuity. Isolated/orphaned and single block width strings of blocks were removed in order to only report Mineral Resources with a reasonable prospect of economic extraction. |
The Company will file the National Instrument 43-101 Technical Report that supports the disclosure of the Mineral Resource Estimate within 45 days of this news release.
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. 1.5m capped composites were used for grade interpolation. Search ellipse ranges for Measured and Indicated Mineral Resource grade interpolation were respectively 20 and 40 m. The bulk density values used in the Mineral Resource Estimate were derived from 71 samples collected during re-assaying of historical drill core completed by the Company.
The database for the Mineral Resource Estimate consisted of 399 drill holes totalling 69,924 m of which a total of 341 drill holes totalling 15,034 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. The Company’s seasoned exploration team carried out extensive data verification on the historical database by re-sampling 2,080 gold-silver mineralized historical sample intervals, being approximately 20% of sample intervals used in the Mineral Resource Estimate (being those samples above the 0.2 g/t cut-off grade) and approximately 5% of all sample assay results in the entire historical database. Drill hole collar location verification surveying and standard bulk density re-measurement was also completed, this confirmed historic collar locations were accurate and historic bulk density measurements were valid.
The Company has also entered into an agreement with Gold Standard Media (“GSM”) and with Future Money Trends LLC (“FMT”) to raise awareness of the Company’s shares among investors. The engagement is for 12 months of services, with amounts payable as follows: USD $100,000 on acceptance of the TSX Venture Exchange, USD $100,000 within 3 months, USD $100,000 within 6 months and USD $100,000 within 9 months. Subject to TSX Venture Exchange acceptance, the activities will commence late November, 2022 and are for a period of one year.
Neither GSM nor FMT nor its affiliates own any securities of the Company. FMT manages a marketing team headquartered in Austin, Texas, and has conducted marketing services for a broad range of companies listed on exchanges from the TSX Venture Exchange to the New York Stock Exchange since 2010. FMT and GSM are controlled by Kenneth Ameduri.

Zacatecas has two key projects. The Esperanza Gold Project in Morelos State, Mexico and the Zacatecas Silver Project in Zacatecas State, Mexico.
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. Zacatecas 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.
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. . On December 15, 2021, Zacatecas announced a Mineral Resource Estimate at the Panuco Deposit consisting of 2.7 million tonnes at 187 grams per tonne (g/t) silver equivalent (AgEq) (171 g/t silver (Ag) and 0.17 g/t gold (Au)) for 16.4 million ounces AgEq (15 million ounces silver and 15,000 ounces gold) (See news release dated December 14, 2021).
The 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 Pan American Silver Corp. claims and El Orito, which is owned by Endeavour Silver.
