Construction of Santacruz's Rosario Mill on Schedule for December Commissioning / Update on Rosario Drill Program

Vancouver, B.C. -- Santacruz Silver Mining Ltd. ("Santacruz" or the "Company") (TSX.V:SCZ) is pleased to announce that the mill construction at the Rosario Project in the Charcas Mining District, San Luis Potosi, Mexico is proceeding on schedule and on budget towards commissioning of the mill facility in December, 2012.

As reported on June 7, 2012, Santacruz purchased a mill from Goldcorp Inc.'s Mexican subsidiary, Minera Nukay. The mill infrastructure will be set for an 800 ton/day capacity. Mill site preparations were completed including leveling of the ground at the mill location and pouring of concrete foundations for both the mill and the crushing facilities. The mill arrived onsite as scheduled during the second week of September 2012 and the Company commenced the assembly of the mill components including the flotation cells and thickeners. The Company has successfully achieved all of its Rosario mill schedule milestones to date and is forecasting all construction to be completed in late November, with commissioning of the mill facility anticipated to begin in December. Achievement of these milestones would position the Company to reach commercial production in the first quarter of 2013.

President, Arturo Préstamo stated "We would like to thank our Chief Operating Officer, Francisco Ramos and our dedicated team at the Rosario property for their continued hard work in setting up and constructing the mill to date. As a result the mill construction is on schedule and within our specified budget. Rosario combined with our two other advanced-stage properties, Gavilanes and San Felipe, provide us with great confidence that we will achieve our targeted goal of becoming a mid-tier silver producer."

Rosario Exploration Update - Drilling Extends High Grade Silver Mineralization

Exploration drilling north-west of the current resource at the Rosario project in San Luis Potosi, Mexico, continues to extend the high grade silver mineralization within the Rosario I & II veins.

At present, two drill rigs are active on the Rosario property. Results from the first three holes have been received, all of which successfully intersected the Rosario vein:
  • Drill hole RS-01 consisting of 504.48 grams per tonne (gpt) silver equivalent.
  • Drill hole RS-02 consisting of 823.36 gpt silver equivalent.
  • Drill hole RS-03 consisting of 721.14 gpt silver equivalent.
Drill results are as follows:

President, Arturo Préstamo stated "The results of the current drilling program prove the potential for additional resources at Rosario. This will allow us to extend the operational mine-life and fits with our strategy of continuing to replenish the known resources as we bring the project into production."

Over the next twelve months at the Rosario project, the Company will focus on increasing production, improving the present resource classification, developing additional resources to the north-west of the known mineralized areas and adding mine-life to the project. Exploration planned over this time period will include 30 drill holes consisting of 4,000 metres in depth. The Company is also working to develop a new NI 43-101 Technical Report on the Rosario project.


Samples were prepared at the ALS Chemex facility in Durango, Mexico, and were assayed at ALS Chemex in Vancouver, Canada.
