Santacruz Advances Main Ramp Intersecting Rosario I, the Northwest Ramp Crosscut Intersects Rosario II Vein

September 12, 2013

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sep 12, 2013) - Santacruz Silver Mining Ltd. ("Santacruz" or "the Company") (TSX VENTURE:SCZ)(1SZ.F) reports that the new access to Rosario I and II veins (lower and upper vein respectively) is now contributing to its milling throughput at the Rosario mine.

Main Ramp (Level One)

On August 25th the main access ramp (Level One) ("Main Ramp") intersected the Rosario I vein with two new working faces subsequently being opened. Additionally, four high-grade producing stopes (two to the southeast and two to the northwest) are currently being developed at the vein. The initial development work on this section of the Rosario I vein has revealed vein widths of approximately 2 meters, this being greater than the 1.4-meter width previously utilized in the resource calculation. These initial assays taken across the two-meter width show higher grades than those used in the resource calculation:

1,055 g/t Ag, 0.13 g/t Au, 7.8% Zn, and 6.1% Pb over a 2 meter true width.

Development of the Main Ramp is on target to extend from Rosario I to the Rosario II vein by mid-October 2013. At this time, two additional working faces will be added to the mine production with two new production stopes immediately being developed. Production stopes will continue to be added along the 500-meter strike of the currently defined resources.

Northwest Ramp (Level One)

As noted in the Company's press release of April 18th, 2013 Santacruz developed the Northwest Ramp in order to expedite access to the Rosario I and II veins. Previously the Northwest Ramp reached Rosario I sulphide mineralization at Level One. Development work at the Rosario I vein is continuing with one producing stope currently feeding the mill. A crosscut from the Northwest Ramp at level One reached the Rosario II vein on September 5th, this has increased the working faces to five. The initial assay results received back from the Northwest Ramp also show higher grades than those in the resource calculation:

509 g/t Ag, 0.22 g/t Au, 3.4% Zn and 0.5% Pb, over 2.0 meters true width

Two additional producing stopes from the Rosario II vein are expected to contribute to our production in the short term, 4Q13.

Production Summary / Outlook

Current production is derived from five working faces and one producing stope. Production levels are currently increasing with the objective to reach 500 tonnes per day by the end of 1Q14. Head Grades at the Rosario mill currently are: 255 g/t Ag, 0.25 g/t Au, 2.1% zn, and 1.03% Pb. Mill recoveries are within the forecast range averaging (as shown in the table below).

Mill Recoveries

Ag Au Zn Pb
%
Lead Concentrate 88.1 56.5 5.4 87.8
Zinc Concentrate 5.3 20.2 88.4 4.0
Total Recoveries 93.4 76.7 93.8 91.8

Mr. Arturo Préstamo Elizondo, President and CEO of Santacruz Silver states:

"Reaching the Rosario I and Rosario II veins is a significant milestone for the Company. We are very excited that the grade and width of the initial intersections at both Rosario I and II exceeded forecasted levels. This, together with new working faces and stopes being developed at both Rosario I and II will allow the company to meet and maintain its primary production objective of 500 tonnes per day by the end of 1Q14. The staff at Rosario Mine, led by Francisco Ramos, will continue to move forward diligently to meet and maintain the growth of our Rosario Mine."

Method of Analysis

Mine samples were prepared at the Company's lab facility at its Rosario lab and analyzed by atomic absorption for Cu, Zn, Pb, Bi, Co, Mn, Sb, Cd and Fe. Gold and silver are analyzed by fire assay method. The Rosario laboratory follows the quality control methodology recommended by CANMET of Canada, such as assaying of blanks, duplicate samples, and check assays by commercial laboratories such as ALS Chemex. The Rosario lab is not yet officially certified to all the standards.

Quality Control

The quality assurance-quality control (QA-QC) of Santacruz at the Rosario mine has been described in detail in Gustavson Associates' NI 43-101 report of December 19, 2012.
