Santacruz Silver Reports First Quarter 2018 Production Results

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

the operating results from the Veta Grande Project in Zacatecas, Mexico and the Rosario Project in San Luis

Potosi, Mexico for the first quarter of 2018.

The Company produced a total of 154,175 silver equivalent ounces in Q1 2018 (Q1 2017 – 223,968; Q4 2017

– 139,670). As compared to Q1 2017, the decreased production reflects 30% less tonnes milled at the

Rosario Project and a 32% decrease in the average silver equivalent head grade at the Veta

Grande Project. As compared to Q4 2017, the increased produc tion reflects an 11% increase in the average

silver equivalent head grade at the Rosario Project and a 98% increase in tonnes milled at the Veta Grande

Project offset by 22% decrease in the average silver equivalent head grade.

“During Q1 of 2018 managem ent focussed activities on aggressively developing the Veta Grande main ramp

in order to access in situ mineralized material from Q3 onwards. This strategy has resulted in lower head

grades and reduced metal production for the short run but will pave the way for achieving targeted production

for Q3 and beyond.” stated Arturo Prestamo . He continued, “At Rosario the millfeed continued to be a blend

of development muck and mineralized material from production stopes. During Q2 the percentage of

development m uck will decrease as more production stopes come online and by Q3 we expect to be at

targeted production and head grade levels.”

Update - Veta Grande Project

Two important initiatives are currently ongoing at the Veta Grande Project. One is the ongoing first phase of a

surface drilling campaign consisting of 6,000 metres on the Veta Grande vein and a 3,000 -metre underground

drill program on the Armados vein . The plan is to com plete a 20,000-metre drill program during 2018 funded

by Carrizal Mining, S.A. de C.V. To this end, a second surface drill rig is expected on property shortly. With

respect to the current program, the first two surface drill holes have been completed and five underground drill

holes been completed. Assays are pending.

The other initiative is to drive a second production ramp to access the Armados vein while concurrently

continuing with development work on the Veta Grande vein. .

Update - Rosario Project

As disclosed previously, during Q4 2017 t he Company took the decision to consolidate all of its Rosario

Project mining operations to the Membrillo Prospect. Mine development has now reached Level 3 and mine

production is increasing. Management anticipates that the targeted production rate (350 tpd) and head grade

will be achieved by the end of Q2.

Rosario Project

The decisions to commence production at the Rosario Mine, Cinco Estrellas Property and Membrillo Prospe ct

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 ris ks 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 thi s production decision. Production and economic

variables may vary considerably due to the absence of a complete and detailed site analysis according to and
