Zacatecas Silver Enters into 10,000 Metre Diamond Drill Contract with Major Drilling and Secures Access Agreement with The Ejido "Panuco" Municipality, Zacatecas

VANCOUVER, BC, May 6, 2021 /PRNewswire/ - Zacatecas Silver Corp. ("Zacatecas Silver" or the "Company") (TSXV: ZAC) is pleased to announce it has achieved a key milestone to commence its drilling activities at its highly prospective Panuco Silver Deposit and San Gill Breccia Zone by securing an access agreement with the Ejido "Panuco" Municipality, Zacatecas.  Further, Zacatecas Silver has entered into a 10,000 metre diamond drill contract with  Major Drilling de Mexico C.V. ("Major Drilling"). 

Highlights:

• Major Drilling, a key service provider in the Zacatecas region, has the skilled personnel to efficiently carry out the extensive drill program planned by Zacatecas Silver Corp.
• A 10,000 metre diamond drill program will be immediately carried out after receipt of final drill permits, which are expected shortly.
• The Panuco Silver Deposit is a highly prospective silver deposit with numerous underexplored high-grade silver shoots.
• San-Gill Breccia Zone is an underexplored silver-gold-base metal mineralized breccia that is over 800 m in strike length and between 20 to 40 m wide.

The Panuco Silver Deposit is located in the north of the Zacatecas Property and is the most advanced prospect.  Panuco has an historic inferred mineral resource of 19,472,901 ounces Ag Eq. (cut-off 100 g/t Ag Eq.) from 3,954,729 tonnes at 153.2 g/t Ag Eq (136 g/t Ag, 0.14 g/t Au, 0.012% Pb, 0.11% Zn) (the "Historical Estimate"). See "Historical Resource Estimate Information" set forth below.

The drill program at the Panuco Silver Deposit will focus on the vein system outside of the historical resource estimate.  A total of three veins will be drilled — Panuco NW, Panuco Central and Tres Cruces — which remain open at depth and along strike. These are high priority drill targets.  Figure 1 below sets forth the extensive silver vein system at the Panuco Silver Deposit.

The San Gill Breccia Zone is relatively unexplored. The breccia has a strike length of approximately 800 m, is up to 40 m wide, and is most likely vertical.  The north-south orientation of the breccia is highly significant as gold-rich epithermal veins within the district are generally oriented north-south. This is supported by the hole MG 11-01 intersect. Only four holes of the historic nine drilled targeted the breccia. It is an extremely robust exploration target and significant further work is required.

About Zacatecas Silver Corp.

The Zacatecas Silver property 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 7826 ha (19,338 acres) of ground that is highly prospective for low and intermediate sulphidation silver-base metal mineralization and potentially low sulphidation gold-dominant mineralization.

The property is 25 km south-east 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. There are four main high-grade silver target areas within the Zacatecas concessions: the Panuco Deposit, Muleros, El Cristo and San Manuel-San Gill.  The Property also includes El Oro, El Orito, La Cantera, Monserrat, El Peñón, San Judas and San Juan silver-base metal vein targets. These targets are relatively unexplored and will be the focus of rapid reconnaissance review

Historical Mineral Resource Estimate Information

In 2019 Santacruz Silver Mining Ltd. completed an updated historical resource estimate as set forth in the technical report titled "Technical Report – Veta Grande Project, Zacatecas State, Mexico" dated 20^th of August 2019. The report was prepared by Van Phu Bui, P. Geo and Michael O'Brien, P. Geo, and filed on www.sedar.com ("2019 Panuco Historical Resource"). The 2019 Panuco Historical Resource reported 3,954,729 tonnes at 153 g/t Ag Eq. (136 g/t Ag, 0.14 g/t Au, 0.012 % Pb, 0.11% Zn) for a total of 19,472,901 ounces Ag Eq. (cut-off 100 g/t Ag Eq.).  The 2019 Panuco Historical Resource used "inferred mineral resources", which is a category set forth under CIM Definition Standards for Mineral Resources & Mineral Reserves adopted on May 10, 2014.

The 2019 Panuco Historical Resource was calculating using 75 drill collars, 866 down hole surveys and 2,607 assayed samples.  A surface trench database totalling 183 trenches with 1,813 samples was used.   Resource blocks were defined using with dimensions of 20 m along strike and down dip, and 1 m across strike.  Grades for gold, silver, lead and zinc were interpolated into blocks using the following estimation algorithms: central — ordinary kriging and NW and Tres Cruces — inverse distance squared.  Assumptions used in the 2019 Panuco Historical Resource include the following metal prices: gold price of US $1,350/oz, silver price of US $16/oz, lead price of US $0.90/lb and zinc price of US $1.10/lb. The 2019 Panuco Historical Resource assumed recovering similar to the Veta Grande System being: gold at 52.2%, silver at 62.1%, lead at 87.9% and zinc at 78.6%.  The Company considers the 2019 Panuco Historical Resource relevant due to its identification and modelling of the Panuco deposit. 

The Company has not done sufficient work to classify the 2019 Panuco Historical Resource as a current mineral resource or mineral reserves, and the Company is not treating the historical estimate as current mineral resources or mineral reserves.  Although the historical resource estimate is considered reliable, 8% of the drill core intervals used in the resource calculations was re-sampled and submitted these to ALS for independent assay. Further, additional data verification including resurveying of select diamond drill holes collars; review of graphic drill core logs, comparison of these logs with remaining half-cut core, and a cross-check of select geological logs agonist database entries; and a check of original ALS assay certificates against the assays and drill hole database. Remodelling of the current Panuco resource is ongoing pending receipt of check sample assays.
