VANCOUVER, B.C — April 18, 2013 — Santacruz Silver Mining Ltd. (TSXV:SCZ) is pleased to announce that it has reached commercial production at the Rosario Mine in Charcas, San Luis Potosi, Mexico.

The commissioning of various mill circuits commenced in December 2012 and was ongoing through January 2013. During February and early March the Company ran low grade mill feed through the mill circuits and confirmed that all circuits were functioning to specification. The initial mill feed used for commissioning was extracted from veins exposed on surface at the Rosario Mine. In the last half of March the Company began milling ore and making final adjustments to the mill circuits with the result that effective April 1, 2013 the Rosario Mine is in commercial production. In addition, Santacruz has negotiated the purchase of approximately 5,000 tons of ore from a nearby private mining operation to ensure continuous mill operation.

The initial production capacity of the mill facility is currently 300 tons per day (“tpd”). Substantially all additional milling equipment is onsite, which will allow for the next expansion phase to reach a projected production capacity to 700 tpd. This Phase 2 Expansion is planned to be completed by year-end.

The Company is working two adits to provide immediate access to the Rosario I and Rosario II veins near the surface. These adits, one accessing the veins from the southeast and the second from the northwest are supplying initial plant feed. In parallel the Company is developing an underground ramp of approximately 120 meters to intersect the Rosario I and Rosario II veins. Santacruz is anticipating intersecting the veins within one month, after which the ramp development will continue parallel to the veins down dip in the footwall.

Long term planning has developed a flexible sublevel mining method, which will accommodate the variably dipping veins with minimum dilution. This will allow efficient and safe mining of the Rosario I and Rosario II veins.

Average throughput for the mill is targeted at 150 tpd for Q2 and Q3 of 2013 increasing towards 200 tpd in late Q4. In Q2 2014 Santacruz is targeting a further throughput increase to 500 tpd when the underground development is scheduled to be completed and additional working faces on the main Rosario I and Rosario II veins become operational.

President Arturo Prestamo states “We are very pleased with the on-site developments to date that have brought Rosario to commercial production on time and under budget. Our staff should be commended for a job well done for constructing the Rosario mill on time and under budget with capital expenditures coming in approximately 20% lower than our original budget of US$12.5 million. Our COO, Francisco Ramos, has once again done an extraordinary job building and leading a strong and motivated operational team. This is an important milestone for the Company as it sets the platform for future growth as we work towards our goal of becoming a mid-tier silver producer.”

Santacruz Silver currently employs approximately 250 staff and contractors at the Rosario Mine. The Company anticipates production of 500,000 silver equivalent ounces at the Rosario Mine in the calendar year 2013.
