Santacruz Silver Reports Q1 2021 Production of 706,978 Silver Equivalent Ounces

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

reports its operating results from the Zimapan Mine located in Zimapan, Hidalgo, Mexico and the

Rosario Project located in Charcas, San Luis Potosi , Mexico, for the first quarter 2021 (“Q1”). The

Company is not including production from the Veta Grande Project in this report as operations at

Veta Grande were suspended during Q1 2020.

Production Highlights:

• Silver equivalent ounces produced 706,978

• Silver head grades increase 9.4 % at Zimapan Mine as compared to Q1 and Q4 2020

• Increased tonnage throughput from Lomo del Toro zone of the Zimapan Mine from 4,000 during

January and February to 6,000 tonnes for the month of March

• New mining method introduced in late March at Rosario that is expected to significantly reduce

costs by less handling of waste material.

Carlos Silva, Santacruz’s COO stated, “ As we keep advancing our workings deeper into the higher -

grade Lomo del Toro manto and increase the tonnage mined from this zone, we are seeing a

corresponding increase in head grades at our Zimapan Mine. We are progressing well towards our

objective of reaching 15,000 tonnes per month of mill feed from this higher-grade area by the end of

the second quarter ”. Mr Silva continued; “We expect further efficiencies at our Rosario Project

during Q2 as a result of a revised mining plan which results in less waste material being handled.

These very encouraging improvements were unfortunately partially offset by an unstable power

supply from Mexico´s Comision Federal de Electricidad (Mexico´s power supply Company). The

unstable power supply impacted the mill throughput at both mines in February as motors for the ball

mills w ere damaged. The matter was resolved in early March but mill throughput was materially

reduced for eight days”.

COVID-19 Update

The Company continues to take all appropriate measures to prevent COVID -19 among the work

force and local communities and to monitor the effectiveness of these measures in mitigating any

potential impact on business activities. The Company's actions have been successful to date and

the pandemic has not had any material impact on the business.

* In the above tables Ag Eq has been calculated as follows:

2021 Ag Eq was calculated using metal prices of: Ag $25.00/oz, Au $1,925/oz, Pb $0.85/lb, Zn $1.05/lb and Cu $3.00/lb.

2020 Ag Eq was calculated using metal prices of: Ag $17.85/oz, Au $1,480/oz, Pb $0.92/lb, Zn $1.09/lb and Cu $2.80/lb.

Silver Equivalent Comparative Production

As noted in the tables above, there is a significant reduction in silver equivalent ounces produced in

Q1 2021 as compare d to that produced in Q1 and Q4 2020. This negative change in production is

due in large part to th e metal prices used for this calculation in 2021 as compared to 2020. For

example, had the Company used the 2020 metal price deck for its silver equivalent production

calculation at the Zim apan Mine in Q1 2021, the reported silver equivalent ounces produc ed would

have been 868,750, an increase of 9.1% over the current reported balance. On a comparative basis

within any particular fiscal year or between periods in different fiscal years where the metal price

decks are relatively equivalent, this computatio n is useful for comparing production from one period

to another. When the price decks are not relatively equivalent, the usefulness of this production

indicator is diminished.
