Vancouver, British Columbia--(Newsfile Corp. - July 28, 2020) -  Santacruz Silver Mining Ltd. (TSXV: SCZ) (the "Company" or "Santacruz") through its wholly owned subsidiary, Carrizal Mining, S.A. de C.V. ("Carrizal"), has entered into a legally binding term sheet (the "Term Sheet") with Minera Cedros, S.A. de C.V. ("Minera Cedros"), a wholly owned subsidiary of IndustriasPeñoles, S.A.B. de C.V. to acquire (the "Transaction") the Zimapan property and related assets (the "Zimapan Mine") located in Zimapan, Hidalgo State, Mexico for total consideration of US$20 million (plus applicable Mexican Value Added Tax of US$3.2 million) (the "Purchase Price").

The Zimapan Mine is currently under lease by Carrizal from Minera Cedros expiring December 31, 2020. The Zimapan Mine has had a long mining history with recent production for over the past 10 years being carried out by Carrizal under a mining lease agreement with Minera Cedros. During this time, mining operations were based on underground diamond drilling programs. Santacruz completed the acquisition of Carrizal in October 2019.

Assets to be acquired pursuant to the Transaction include:

• Zimapan mill facility (the "Zimapan Mill") which is a 75,000 dry metric tonnes (DMT) per month facility with zinc, lead and copper circuits. Over the past five years the Zimapan Mill has produced an annual average of 12,400 tonnes of zinc, 3,300 tonnes of lead, 1,850 tonnes of copper and 1,290,000 ounces of silver from an average annual throughput of 700,000 tonnes of mineralized material generating an average of 4,681,000 ounces silver equivalent* (source: Carrizal mine production records).
• Surface and underground infrastructure including electrical and other necessary infrastructure to carry on day to day operations.
• 34 mining concessions covering an area of 5,139 hectares. The mining concessions are located seven kilometers from the municipality of Zimapan. To date, Carrizal has identified 14 mineral zones that are characterized as polymetallic replacement mineralization of Pliocene age. Within the mineral zones, silver, lead, zinc and copper minerals have preferentially replaced the carbonate host rocks and pre-existing skarn bodies to produce disseminated, semi-massive sulphide and massive sulphide bodies that occur in proximity to monzonitic intrusions and quartz-feldspar porphyry dikes.

Pursuant to the Term Sheet, if the parties have not executed definitive agreements relating to the Transaction, and completed the Transaction, on or before December 15, 2020 (the "Closing Deadline"), the party responsible for such lack of performance must pay the other party a break fee in the amount of 20% of the Purchase Price, subject to the extension provisions described below. Accordingly, if the Company is unable to secure funding of the entire Purchase Price or is otherwise unable to complete the Transaction by the Closing Deadline or such later deadline as may result from one or more extensions granted by Minera Cedros (as described below), then Carrizal will be required to pay a break fee equal to 20% of the Purchase Price to Minera Cedros.

If Carrizal pays all outstanding royalties owing to Minera Cedros in connection with the existing lease of the Zimapan Mine, currently amounting to approximately US$1.05 million, on or before October 31, 2020 and subject to Carrizal maintaining a guaranty through a bank letter of credit or similar instrument in favor of Minera Cedros in the amount of US$1 million with an expiry date of February 15, 2021 or later, then Carrizal has the right to request an extension of the Closing Deadline to January 31, 2021 and can thereafter further request an extension of the Closing Deadline to March 31, 2021 if such guaranty is increased to US$2 million and the Purchase Price is increased by 10% after December 15, 2020.

Carlos Silva, Santacruz's CEO, stated, "This would be a transformational transaction for Santacruz to add the Zimapan Mine, which I have had the privilege to lead throughout the last 12 years, to the Company's existing mining projects". Mr. Silva continued; "This acquisition is expected to pave the way for the future growth of Santacruz towards becoming a mid-tier silver producer. We wish to thank Peñoles management for their support throughout this process."

Completion of the Transaction remains subject to a number of conditions, including receipt of all necessary regulatory approvals including approval of the TSX Venture Exchange ("TSXV") to the Transaction which will constitute a "Fundamental Acquisition" pursuant to TSXV Policy 5.3.

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.
