Santacruz Silver Reports Q1 2022 Production of 1,391,590 Silver Equivalent Ounces

Vancouver, B.C. – Santacruz Silver Mining Ltd. (TSX.V:SCZ) (the “Company” or “Santacruz”)

reports production of 1.39 million silver equivalent ounces from its Zimapan Mine in Mexico (the

“Mexican Operations”) and its operations in Bolivia (the “Bolivian Operations”) which includes the

a 45% interest in the Bolivar Mine and the Porco Mine, and a 100% i nterest in the Caballo Blanco

group of mines and the San Lucas Trading Company. Santacruz acquired the Bolivian Operations

from Glencore on March 18, 2022 (see the Company’s press release dated March 18, 2022 ).

Accordingly, Santacruz’s first quarter production results include only 13 days producti on from the

Bolivian Operations.

Consolidated First Quarter 2022 Production Highlights:

• silver 469,829 oz (+47.6% vs Q4 2021 and +44.4% vs Q1 2021);

• lead 1,493 tonnes (+47.5% vs Q4 2021 and +58.0% vs Q1 2021);

• zinc 6,325 tonnes (+83.8% vs Q4 2021 and +176.8% vs Q1 2021);

• copper 419 tonnes (-14.1% vs Q4 2021 and +18.4% vs Q1 2021)

• Consolidated Production expressed in silver equivalent ounces 1,391,590 AgEq; (+ 65.3% vs Q4

2021, and +96.8% vs Q1 2021)

Carlos Silva, Santacruz’s C EO stated, “The inclusion of 13 days of production from our Bolivian

Operations have made a significant contribution to our Q1 2022 operating results. Based on current

metals prices, we expect that our cash flow from operations will fund the deferred purchase price for

the acquisition of the Bolivian Operations from Glencore. At our Mexican Operations, we set a 2021

objective of replacing the production from the now closed Rosario mine by deploying its

underground mining equi pment to Zimap an to increase production at Zimapan with no additional

capital investme nt. This equipment has been initially deployed on past producing areas at the

Zimapan mine leading to an increase in tons mined with a small reduction in head grade resul ting in

increased production in Q4 21 and Q1 22 . We continue to anticipate additiona l growth at Zimapan

as the mine ramps up to higher throughput levels as well as improved silver head grades due to

ongoing developments to higher grade areas over the next few quarters”.

Mr. Silva added; “The acquisition of Glencore´s Bolivian assets is a major development for our

Company. We are continuing to advance the transition process, and similarities in culture, ideology

and values appear to be resulting in a smooth and efficient progression of synergies with respect to

the Bolivian Operations. We will keep executing our planned integration process with discipline and

industry best practices while incorporating the Santacruz philosophy, with the goal of creating value

to our stakeholders”
