VANCOUVER, March 5, 2018 /PRNewswire/ - Santacruz Silver Mining Ltd. (TSX.V:SCZ) (the "Company" or "Santacruz") reports its  operating results from the Veta Grande Project in Zacatecas, Mexico and Rosario Project in Charcas, San Luis Potosi, Mexico for the fourth quarter ("Q4") and year ended December 31, 2017 and provides an operations update.

The Company produced a total of 865,458 silver equivalent ounces in fiscal 2017 (2016 - 970,332) including fourth quarter production of 139,670 silver equivalent ounces (2016 - 242,048).  The decreased production is a result of a number of factors including a delayed production start at the Membrillo Prospect, lower than expected head grades from the previously mined mineralized material ("chorros") at the Veta Grande Project and from a temporary suspension of operations at the Veta Grande Project in November 2017 (see press release dated November 22, 2017). Mining operations were further challenged by a deficiency of working capital.

Arturo Prestamo, Santacruz's President and CEO stated "In 2017 Santacruz made several positive steps towards solidifying its operations base including the retirement of the senior JMET debt facility, the negotiation of the outright acquisition of the Veta Grande Project, the appointment of Carlos Silva as COO, and optioning 20% of the Company's Zacatecas mineral portfolio to Carrizal Mining, S.A. de C.V."  Mr. Prestamo continued "Further, as a first step to address the Company's current working capital needs Santacruz has entered into a services agreement with Carrizal Mining to provide to it certain mining related services that will generate approximately US$1.1 million of monthly cash flow to Santacruz."

Project Updates

Veta Grande Project

Two important initiatives are currently ongoing at the Veta Grande Project.  The first initiative is the expansion of the Veta Grande mill capacity to 750 tpd which is well advanced. Commissioning of this expansion is expected to start in late March. The second initiative is the conversion of the source of mineralized millfeed to the Veta Grande mill from the chorros to in situ vein material from the Veta Grande and Armados veins.  In connection with this matter the first phase of a surface drilling campaign consisting of 6,000 metres is underway on the Veta Grande vein and a 3,000-metre underground drill program on the Armados vein is scheduled to commence within 10 days.  The mill expansion and drilling campaigns are being funded by Carrizal Mining pursuant to the terms of its 20% earn-in on the Veta Grande mineral portfolio.

Rosario Project

The Company recently has recently taken the decision to consolidate all of its Rosario Project mining operations to the Membrillo Prospect.  Mine development has now reached Level 2 and mine production is increasing.  Once the mine operations at the Membrillo Prospect achieve target amounts the Company will recommence mining operations at the Cinco Estrellas Property.

CONSOLIDATED PRODUCTION RESULTS – 2017 Q4 AND 2017 ANNUAL

VETA GRANDE PROJECT PRODUCTION RESULTS – 2017 Q4 AND 2017 ANNUAL

ROSARIO PROJECT PRODUCTION RESULTS – 2017 Q4 AND 2017 ANNUAL

Sampling and Laboratory

The reported head grades have been estimated from assay results of samples collected from stockpiles of mined mineralized material. The reported stope grades are of assay results of underground chip samples collected across the vein and at an average interval of three meters along the strike length of the vein. Blanks, standards and duplicate control samples are not utilized in the sampling procedure.

Samples collected from the Rosario and Veta Grande Projects are assayed at the Rosario and Veta Grande laboratories, respectively. Both laboratories are owned and operated by Santacruz and the facilities are meant to serve the mining operations at the projects. The Rosario and Veta Grande laboratories are not independent of the Company and do not hold ISO certification. Samples are prepared by drying, crushing, rifle splitting and pulverizing to <75 microns passing 200-mesh. Samples are analyzed by 3-acid digestion and Atomic Absorption Spectrometry. Gold and silver are further analyzed by fire assay with gravametric finish.

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. 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.
