Santacruz Silver Signs Letter of Intent to Sell Gavilanes Project for US$3.5 Million

Vancouver, B.C. - Santacruz Silver Mining Ltd. (TSX.V:SCZ) ("Santacruz" or the "Company") announces that it has signed a letter of intent ("LOI") to sell its interest in the Gavilanes Project in Durango, Mexico to an arm's length third party gold and silver producer (the "Purchaser"). The LOI contemplates the sale to the Purchaser of 100% of the Company's interest in the Gavilanes Project for US$3.5 million plus applicable value added tax.

Gavilanes is located approximately 110km WNW of Durango City in the municipality of San Dimas in Durango State, Mexico. The property is located within the central part of the Sierra Madre Occidental and includes 10 mining concessions covering a total area of 8,832 hectares.

"Continuing with our plan to focus on our producing assets within the Company, management has made the decision to divest the Gavilanes Project," stated Arturo Préstamo, President and CEO of Santacruz. "The Company is transitioning into a multi-mine Mexican silver producer that we expect will generate solid cash flow as we grow. The monetization of Gavilanes would allow us to further improve our operations on the Company's two producing assets, and, once completed, will serve to fulfill the remaining obligations under the JMET, LLC facility, thereby unencumbering the Company's assets."

The LOI is non-binding and the transaction is subject to, among other things, the parties entering into a definitive agreement which will contain customary terms and conditions for a transaction of this nature. The transaction is expected to close on or before August 15, 2017.

Rosario Project

The decisions to commence production at the Rosario Mine, Cinco Estrellas Property and Membrillo Vein 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 according to and in accordance with NI 43-101.

Veta Grande Project

The decision to commence production at Veta Grande Project was not based on a feasibility study on mineral reserves demonstrating economic and technical viability. 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 according to and in accordance with NI 43-101.
