Vancouver, B.C. MAG Silver Corp. (TSX: MAG; NYSE MKT: MVG) ("MAG" or the "Company") reports new exploration results from the Valdecañas Vein on the Minera Juanicipio S.A. de C.V. ("Minera Juanicipio") Joint Venture property (owned 44% by MAG and 56% by Fresnillo plc). Four new exploration step-out holes were targeted approximately 100 metres below the existing "Deep Zone" Indicated and Inferred Resources (see press release dated May 27, 2014). The four holes were drilled on 150 metre centres over a strike length of approximately 500 metres below the en echelon overlap zone between the East and West Valdecañas Veins and include the three widest and deepest intercepts to date on the property (see Table 1). This new zone appears to be the extension of the southwest dipping Valdecañas Vein system and it remains open to depth along the entire strike length within the Joint Venture boundary.

These intercepts widen progressively up to 32.09 metres (true widths) towards the east in the central portion of the property, significantly extending the widening Deep Zone to depth. The intercepts also show significant amounts of calc-silicate (skarn) alteration in and around the veins and the first significant copper values for the entire area; both indications of higher temperature mineralization conditions. The high silver and gold in Holes P2 and P3 coincide with zones of overprinted quartz veins that cut across earlier base-metal rich calc-silicate vein stages, indicating superimposition of an additional precious-metals rich vein stage. 

"We are extremely pleased to see such a dramatic widening in tandem with strong grades in the Valdecañas Vein at these depths. The geological providence of this system continues to deliver significant results." said George Paspalas, President and CEO of MAG Silver.

(4) Unless otherwise indicated as uncapped, all silver assays over 6,000 g/t were capped at 6,000 g/t and all gold assays over 16 g/t were capped at 16 g/t, consistent with the capping used for the existing Indicated and Inferred Resources (see press release dated May 27, 2014).

Dr. Peter Megaw, the Company's Chief Exploration Officer, added that "the appearance of copper and strong skarn alteration in this area, combined with the later cross-cutting silver-gold rich veining suggests that we may have hit an ore-fluid upwelling zone, which could open up a new exploration target zone along the Valdecañas vein system."

The results reported above are part of ongoing exploration being carried out by Minera Juanicipio, with these four holes being exploration step-outs beneath the previous deepest drilling on the property. In addition to the exploration drilling, ramp advancement and associated surface and underground mining infrastructure continue to be progressed on the Juanicipio property. Metallurgical drilling on the Valdecañas Vein continues with one drill currently operating. 

Qualified Person: Dr. Peter Megaw, Ph.D., C.P.G., has acted as the qualified person as defined in National Instrument 43-101 for this disclosure and supervised the preparation of the technical information in this release. Dr. Megaw has a Ph.D. in geology and more than 25 years of relevant experience focussed on silver and gold exploration in Mexico. He is a Certified Professional Geologist (CPG 10227) by the American Institute of Professional Geologists and an Arizona Registered Geologist (ARG 21613). Dr. Megaw is not independent as he is Chief Exploration Officer (CXO) and a Shareholder of MAG and is a vendor of projects, other than Juanicipio, whereby he may receive royalties. Dr. Megaw is satisfied that the results are verified based on an inspection of the core, a review of the sampling procedures, the credentials of the professionals completing the work and the visual nature of the silver and base metal sulphides within a district where he is familiar with the style and continuity of mineralization.

Quality Assurance and Control: The samples are shipped directly in security sealed bags to ALS-Chemex Laboratories preparation facility in Guadalajara, Jalisco, Mexico (Certification ISO 9001). Samples shipped also include intermittent standards and blanks. Pulp samples are subsequently shipped to ALS-Chemex Laboratories in North Vancouver, Canada for analysis. Two extra pulp samples are also prepared and are analyzed (in progress) by SGS Laboratories (Certification ISO 9001) and Inspectorate Laboratories (Certification ISO 9001) (or other recognized lab). The bulk reject is subsequently sent to CIDT (Center for Investigation and Technical Development) of Peñoles in Torreon, Mexico for metallurgical testing where a fourth assay for each sample is analyzed and a calculated head grade is received on the basis of a concentrate balance. The CIDT also does a full microscopic, XRF and XRD mineralogical analysis.

About MAG Silver Corp. (www.magsilver.com)
MAG is focused on advancing two significant projects located within the Mexican Silver Belt. Our mission is to become one of the premier companies in the silver mining industry. Currently, we are advancing the underground decline towards the high grade Valdecañas and Juanicipio silver vein discoveries in Zacatecas State, all within the joint venture between MAG Silver (44%) and Fresnillo PLC (56%). In addition, we are negotiating surface access in order to further delineate our district scale, 100% owned Cinco de Mayo property in Chihuahua state, where two new silver, lead, zinc discoveries are opening up further growth opportunities for MAG Silver Corp.
