Santacruz Silver Places Rosario Project on Care and Maintenance

Vancouver, British Columbia--(Newsfile Corp. - October 5, 2021) - Santacruz Silver Mining Ltd. (TSXV: SCZ) (the "Company" or "Santacruz") reports that it is suspending operations at the Rosario Project and placing it on care and maintenance. This decision was made following an extensive review by management of the Rosario project operations and strategic options available including the potential sale of the operation.

Management believes that the reallocation of capital and resources to the Zimapan Mine and related satellite properties that have stronger economics is the most prudent course of action at this time. The Company will continue with permitting activities and remediation programs so that the Rosario Project is positioned for a timely restart should project economics justify such.

Carlos Silva, Chief Executive Officer, commented; "We have diligently tried to make the Rosario mine a profitable operation, but due to its narrow vein system and grade variability this is a challenging project." Mr. Silva continued; "Putting the project into care and maintenance will allow us to better evaluate alternatives to maximize the return on this asset."

Rosario Project

The decisions to commence production at the Rosario Mine, Cinco Estrellas Property and Membrillo Prospect were not based on a feasibility study of mineral reserves demonstrating economic and technical viability, but rather on a more preliminary estimate of inferred mineral resources. Accordingly, there is increased uncertainty and economic and technical risks of failure associated with this production decision. Production and economic variables may vary considerably, due to the absence of a complete and detailed site analysis in accordance with NI 43-101.

Zimapan Mine

Production at the Zimapan Mine is not supported by a feasibility study on mineral reserves demonstrating economic and technical viability or any other independent economic study under NI 43-101. Accordingly, there is increased uncertainty and economic and technical risks of failure associated with production operations at the Zimapan Mine. Production and economic variables may vary considerably due to the absence of a complete and detailed site analysis in accordance with NI 43-101.
