Santacruz Silver Announces Gavilanes Maiden Resource Estimation: 6.1 million AgEq Ounces Indicated and 28.3 AgEq Million Ounces Inferred

09:00 EST Tuesday, December 17, 2013

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec. 17, 2013) - Santacruz Silver Mining Ltd. (TSX VENTURE:SCZ) (the "Company" or "Santacruz") is pleased to announce the results of the maiden NI 43-101 Resource Estimate for its Gavilanes silver project located in San Dimas, Durango, Mexico. Based upon a 75 gram per tonne ("g/t") silver equivalent ("AgEq") cut-off, the resources on three of seven known veins, Guadalupe, Descubridora and San Nicolas, as well as the El Hundido stockwork are as follows:

Indicated 953,000 200.5 164.6 0.09 0.06 0.42 0.41
Inferred 5,399,000 163.0 124.6 0.12 0.09 0.40 0.34

Highlights of the mineral resource estimate are as follows:

  • Indicated mineral resources of 6,143,000 AgEq ounces grading 200 g/t AgEq;
  • Inferred mineral resource of 28,294,000 AgEq ounces grading 163 g/t AgEq;
  • Veins remain open along strike and to depth with intermittent surface exposures indicating an untested strike length;
  • The El Hundido stockwork is open down-dip and to the south;
  • Four unexplored veins offer additional potential;
  • Continued drilling in 2014 planned with a target to increase resources.

A cross section is attached to this news release to give a graphic representation of the structures.

Arturo Préstamo, President and CEO, remarked, "Given that drilling to date has only focused on a small portion of our +7,000 hectares of Gavilanes property we are very pleased with the results of the maiden resource estimation. The resource, which is open, together with the significant untapped exploration potential, makes Gavilanes a very strong property within our portfolio of assets in Mexico. Further work aimed at expanding the resource will occur in conjunction with cash flow generation from our currently producing Rosario Mine. In spite of difficult market conditions we are moving ahead on all of our assets while making prudent decisions on behalf of shareholders. We are committed to building a strong mid-tier silver producer with assets in Mexico and Gavilanes is further proof that we are on-track to meet our longer term objectives."

The metal prices used in the silver equivalent estimate are listed below.

Factor
Ag - US$21.55 per ounce 0.69 $/gm
Au - US$1318.00 per ounce 42.37 $/gm
Cu - US$3.25 per pound 71.65 $/%
Pb - US$0.97 per pound 21.38 $/%
Zn - US$0.87 per pound 19.18 $/%

The equation to establish Ag Equivalent is then:

AgEq = (Cu% * 71.65) + (Pb% * 21.38) + (Au g/t * 42.37) + (Ag g/t * 0.69)+(Zn% * 19.18)
(0.69)

100% recovery has been assumed for all metals in this silver equivalent estimate. At this stage of the project no metallurgy has been completed and the reader is cautioned that 100% recoveries are never achieved.

The resource estimate was calculated based on 12,583 metres of HQ diamond drilling in 60 drill holes over approximately 750 meters of strike length and a total of 3,362 assays. The resources were defined to a maximum depth of approximately 300 metres below surface with a total of 198 down hole surveys utilized for control.

The resource estimation was completed by Gary Giroux, P.Eng. of Giroux Consultants and utilized a geological model completed by Hans Smit, P.Geo and Fletcher Bourke, P.Geo. The geological model has six domains; Guadalupe vein (GP), GP envelope, Descubridora vein (DS), DS envelope, San Nicloas (SN) envelope and Stockwork Zone. Assays for each vein, envelope and stockwork zone were examined and a top cap was applied to each variable within each domain. Uniform 2.5 m composites were formed for the vein envelopes and stockwork zone while 0.5 m composites were formed for the two vein domains. Variography was completed for the GP vein, GP envelope and the Stockwork zone. Grades for all variables were interpolated into blocks 2.5 x 5 x 5 m using Ordinary Kriging. For blocks with multiple domains present, a weighted average was determined for the mineralized portion. A specific gravity was established for each domain based on 216 measurements of drill core. Estimated blocks were classified as Indicated or Inferred based on geologic and grade continuity.

Drilling is scheduled to resume at Gavilanes in the second quarter 2014 with the objective of upgrading and increasing resources to develop a mine plan and ultimately mill requirements in line with the Company's technical consultant's suggestions.

Arturo Préstamo, President and CEO, continued, "With this foundation to build from, we will continue to advance the Gavilanes property in order to better understand the full potential of this promising asset."

Sampling and Laboratory

The resource is based on holes drilled with HQ-sized core. Core was sawn in half at site and one half sent to ALS Chemex, a fully accredited and certified laboratory service. Samples were prepared at the ALS Chemex facility in Zacatecas, Mexico, and were assayed at ALS Chemex in Vancouver, Canada. All samples were analysed using a one assay ton fire assay with an AA finish for Au (Au-AA23) and a 48 element ICP method for other elements (ME-MS61). Samples with silver results above 100 g/t by (ME-MS61) were rerun using an aqua regia digestion and ICP-AES or AAS finish (Ag-OG62). A comprehensive QA/QC procedure is followed using standards, blanks and duplicates.

Qualified Persons

All technical information included in this statement has been reviewed and approved by Gary Giroux, P.Eng., Fletcher Bourke, P.Geo., and Hans Smit, P.Geo, who are all independent of the Company and each of which is a qualified person, pursuant to the meaning of such terms in National Instrument 43-101 Standards of Disclosure for Mineral Projects.
