Santacruz Silver Completes Veta Grande Mill Expansion

Vancouver, B.C. -- Santacruz Silver Mining Ltd. (TSX.V:SCZ) (the "Company" or "Santacruz") reports that expansion of milling capacity at its Veta Grande Project to 750 tpd has been completed. The mill is anticipated to be operating at full capacity by early in the second quarter 2018. Currently the mill is operating at 450 tpd and will ramp up in stages until it reaches the new designed capacity.

Management will next focus on enhancing mining efficiencies including the construction of an underground tunnel system that will connect the Veta Grande, San José, Armados and La Flor veins. Upon completion, all underground mining areas will be connected by a new ore haulage level. The consolidation of the underground operations will significantly improve operating efficiencies and is expected to have a positive impact on cash operating costs.

The completion of the mill expansion was commemorated on March 20, 2018, at a ceremony in Veta Grande, Zacatecas, Mexico, in which approximately 150 people attended including several Mexican State and Municipal authorities.

Carlos Silva, Santacruz's COO stated "I commend our Technical Team for achieving this significant milestone ahead of schedule. This new increased milling capacity will allow us to shortly achieve positive cash flow at the Veta Grande operations." Mr. Silva continued; "Our exploration programs will keep advancing to establish and increase our mineral resources with the eventual plan to further expand mill capacity at this historical silver rich mining district of Veta Grande".

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 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.
