Zacatecas Reports Completed Phase One Diamond Drilling at El Cristo with Multiple Silver-Base Metal Rich Epithermal Vein Systems Over 1.5 Kilometre Strike Length.

VANCOUVER, BC, Aug. 30, 2022 /PRNewswire/ - Zacatecas Silver Corp. ("Zacatecas" or the "Company", (TSXV: ZAC) (OTC: ZCTSF) (OTC Markets: 7TV) (Frankfurt: 7TV)) is pleased to report multiple silver and base metal assays from its recently completed phase one diamond drilling at El Cristo vein system. Together with the previously announced results on July 7, 2022, Zacatecas encountered significant silver-base metal mineralization within 22 out of the 28 holes drilled.

El Cristo is the NW strike extension of the prolific and well known Veta Grande vein system onto the Zacatecas Silver property, with most of this extension still untested by drilling.

Highlights:

• Drilling has outlined high-grade silver-base metal mineralization over 1.5 strike kilometres of previously undrilled vein systems across a 750-meter-wide corridor. Mineralization remains open to depth and along strike to the south-east.
• Recent El Cristo results include:
• 9.00 m @ 158 g/t Ag Eq (149 g/t Ag, 0.05 g/t Au, 0.08% Zn and 0.05% Pb) from 17.87 meters downhole (CRI-2022-018)
• 0.82 m @ 592 g/t Ag Eq (84 g/t Ag, 0.14 g/t Au,  3.7% Zn and 11.8% Pb) from 69.10 meters downhole (CRI-2022-020)
• 3.00 m @ 262 g/t Ag Eq (250 g/t Ag, 0.07 g/t Au, 0.1% Zn and 0.04% Pb) from 21.00 meters downhole (CRI-2022-026)
• 2.10 m @ 204 g/t Ag Eq (200 g/t Ag, 0.03 g/t Au, 0.03% Zn and 0.01% Pb) from 47.14 meters downhole (CRI-2022-017)
• 1.60 m @ 181 g/t Ag Eq (175 g/t Ag, 0.02 g/t Au, 0.06% Zn and 0.05% Pb) from 4.40 meters downhole (CRI-2022-027)
• Drilling at El Cristo mainly focused on testing previously undrilled vein systems to the south-east of the project, which are now interpreted to be the western extensions of the Veta Grande vein system.
• The Company completed 28 diamond drill holes at El Cristo for a total of 2,815 meters.

Dr. Chris Wilson, Chief Operating Officer and a Director of Zacatecas comments, "The initial drill program was successful in identifying significant silver-base metal mineralization in 22 out of 28 drilled holes. Our interpretation of the results suggests that the drilled vein system is a western extension of the prolific Veta Grande vein system. Importantly, the intercepts encountered during this initial drilling show that the portion of the Veta Grande vein system identified to date on our property is robust and carries very good grade. We will be using the data from this first round of drilling at El Cristo to model an upcoming program targeting further exploration and expansion at depth and along strike."

Mineralization at El Cristo is of an intermediate sulphidation epithermal type, which crop out with a dilutional zone that is at least 3 km along strike and up to 600 m wide. Within this zone multiple, steeply dipping, northwest-southeast trending veins, which have been mined historically from at least 20 near surface shafts and multiple areas of near surface workings.

El Cristo represents the northwest strike extension of the Veta Grande vein, which has reported, but unverified, historical production of 200 Moz AgEq.  The veins at El Cristo show similar characteristics to those at Veta Grande, have a similar orientation, and are part of the same sigmoidal zone of dilation.

Historically, the El Cristo vein system was only tested by 8 angled diamond drill holes which targeted  veins at depths of below 100 to 200 metres. Of these six were concentrated within a 500 m strike length in the central parts of the veins.

Drill holes targeted the near surface depth extension of the larger surface workings and/or the depth extension of veins around the deeper historical shaft. The 28 holes drilled to date by the Company have been scout holes also designed to test select veins over at least 2 km of strike extension.

Zacatecas Chief Executive Officer and a Director of Zacatecas, Bryan Slusarchuk, states, "The technical team continues to execute efficiently on our silver projects. We have experienced early significant drilling success in two new areas of the property outside of the known Panuco resource with multiple good hits at both Panuco North and El Cristo.The size and scale of the project is increasing.  At the same time, we are seeing multiple intersections in these areas with higher grades than described within the resource itself.

As exploration continues at the silver projects, we are systematically and efficiently advancing the Esperanza Gold Project. The next steps at Esperanza include the production of a current resource estimate and then a Preliminary Feasibility Study (PFS), both of which are underway. The team onsite at Esperanza has recently completed the necessary sampling work for the resource estimate and is awaiting assays for input into the model. At Esperanza, we are targeting the development of a low-cost, low capital intensity and low technical risk oxide gold project with significant stakeholder benefit."

Hole CRI-2022-018 encountered a broad zone of stockwork style oxide mineralization for intercepting 9 meters @158 g/t Ag Eq (149 g/t Ag, 0.05 g/t Au, 0.08% Zn and 0.05% Pb) from 17.87 meters downhole.

Hole CRI-2022-017 intercepted 2.10 m @ 204 g/t Ag Eq (200 g/t Ag, 0.03 g/t Au, 0.03% Zn and 0.01% Pb) from 47.14 meters downhole.

Hole CRI-2022-020 targeted a new vein identified via mapping, over 200 meters south of any historic drilling, intercepting 0.82 m @ 592 g/t Ag Eq (84 g/t Ag, 0.14 g/t Au,  3.7% Zn and 11.8% Pb) from 69.10 meters downhole.

Hole CRI-2022-026 targeted the northwestern strike extension of the 9.53-meter mineralised intercept encountered 50 meters to the southeast in hole CRI-2022-001. Intercepting a 3-meter-wide zone of backfill material grading 262 g/t Ag Eq (250 g/t Ag, 0.07 g/t Au, 0.1% Zn and 0.04% Pb) from 21.00 meters downhole.

Hole CRI-2022-027 targeted the southeastern strike extension of mineralisation encountered in hole CRI-2022-17 and 18. Intercepting 1.60 m @ 181 g/t Ag Eq (175 g/t Ag, 0.02 g/t Au, 0.06% Zn and 0.05% Pb) from 4.40 meters downhole

Additional drilling is required to determine true widths as all hole intercepted veins at an oblique angle. The assays are not capped. Assumptions used in USD for the silver equivalent calculation were metal prices of $24/oz silver, $1,800/oz gold, $1.81/lb zinc, $ 0.90/lb lead and 100% recovery.

Zacatecas follows industry-recognized standards of Best Practice and Quality Assurance/Quality Control. Samples are submitted to ALS in batches of 20 — comprising 16 half cut core samples, one field blank, two certified reference material standards and one staged duplicate. Samples are sealed in plastic bags using single use tie-locks and delivered to ALS Zacatecas — thereby ensuring chain of custody. Since the ALS facility in Zacatecas is only a preparation facility, sample pulps were sent to ALS Ireland for fire assay. To date all batches have passed QAQC and blanks and CRM's were within acceptable tolerance limits. All diamond holes were drilled HQ diameter. Core recovery across all veins was better than 98%.

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 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.

Additionally, Zacatecas has recently announced a transaction to acquire the Esperanza Gold Project from Alamos Gold Inc. 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.

To date, significant core and reverse circulation drilling has occurred at the Esperanza gold project, resulting in a total of 389 drill holes for 69,716 metres. Four targets adjacent to or close to the historical resource were identified to potentially expand the historical resource. The project also hosts seven regional exploration targets, largely untested, that also merit drill testing.

Alamos reported in its most recent annual information form a resource estimate of a measured and indicated resource of 34,352,000 tonnes at 0.98 g/t gold and 8.09 g/t silver for 1,083,366 ounces of gold and 8,936,201 ounces of silver and inferred resource of 718,000 tonnes at 0.80 g/t gold and 15.04 g/t silver for 18,375 ounces of gold and 347,192 ounces of silver. The Company considers this to be an historical resource for the purposes of National Instrument 43-101. Resource blocks were defined using with dimensions of 10 metres (m) by 10 m by five m. The estimation of grades was performed with the ordinary kriging method on capped composites. An added step in the estimation strategy was the utilization of the dynamic anisotropy technique in Vulcan's unfolding options. This added capability allows for a more realistic outcome of the estimated grade's spatial distribution as it follows the folded shape of the deposit. Assumptions used in the resource include the following metal prices: gold price of $1,400 (U.S.) per ounce (oz) and silver price of $22 (U.S.) per oz. The resource assumed the following economic assumptions: recovery of 60.4 per cent at 0.2 g/t to 71.9 per cent at 1.6 g/t for gold, 25 per cent for silver, $2.60-per-tonne mining costs, 64-cents-per-tonne general and administrative costs, $4.20-per-tonne milling costs and a pit slope of 45 degrees. The Company considers the resource relevant due to its identification and modelling of the Esperanza deposit.

The Company has not done sufficient work to classify the 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 resource estimate is considered reliable, the Company will resample a portion of the drill core for the purpose of carrying out a new resource estimate. Furthermore, 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 assay certificates against the assays and drill hole database.
