South American Silver Updates Resource at Escalones in Chile
28 June 2013, Vancouver, British Columbia-South American Silver Corp. (TSX: SAC, US OTCQX: SOHAF) (the "Company") is pleased to announce an updated independent NI 43-101-qualified resource estimate for the Company's 100%-controlled Escalones copper-gold-silver project in central Chile.
- A significant increase in pounds of copper and molybdenum and ounces of gold above assumed economic cut-off of 0.25% copper equivalent (CuEq*), compared to the initial resource dated December 19, 2011.
- Upgrading of approximately a third of the resource to Indicated from Inferred.
Table Comparing 2011 Resource to 2013 (Note Indicated resource is in addition to the Inferred resource)
For further details see tables 1 and 2 below.
Copper Equivalent (Cu Eq*) calculations reflect gross metal content using approximate 3 year average metals prices as of June 25th, 2013 of $3.71/lb copper (cu), $1549/oz gold (Au), $30.29/oz silver (Ag), and $14.02/lb molybdenum (Mo) and have not been adjusted for metallurgical recoveries. An economic cut-off grade of 0.25% copper equivalent was assumed for this report. Contained metal values may vary from calculated values due to rounding.
- The deposit remains open to expansion laterally and down dip.
- Major geophysical targets are still to be drilled.
- The 70 square kilometer Escalones project is located in the world-class central Chilean mining district which includes the nearby El Teniente deposit, which is the world's largest underground copper mine.
Executive Chairman, Ralph Fitch stated "The skarn is a very important part of the mineralized system and, as interpreted from the geophysical surveys, only a small part of it has been drilled to date. This interpretation is corroborated by our deepest intercept of the skarn in hole ES-35 which intersected 9.25 m of 2.11% copper, 17 g/t silver and 0.07 g/t gold before the hole was abandoned for weather reasons. This intercept was not included in the Indicated resource because it is too far from neighboring holes but it does coincide with the interpreted skarn geophysical response. In fact the intersection is 500 metres south and 400 metres deeper than the main skarn resource, clearly indicating the opportunity to extend the mineralized zone in a substantial way. The potential skarn extends for 4-6 km along strike and to several km in depth. Present drilling covers approximately 1 km by 0.5 km of this. The remainder, which is the majority, will be available to drill once permitting is complete.”
Mr. Fitch went on to say "Escalones continues to increase in size and now hosts a substantial gold as well as copper resource. As well, the large reported resource still does not include drilling into the substantial geophysical targets which are interpreted to represent additional skarn and secondary oxide/sulphide mineralization. Also, as stated in an earlier News Release (NR12-21 dated December 10, 2012), initial metallurgical testing suggests that high grade copper sulphide concentrates are achievable which should enhance the value of the property.”

The Escalones mineral resource estimate is based on 53 diamond drill holes (24,939 meters) and 15,880 associated assay values collected through 2013. The resource estimate is categorized as indicated and inferred as defined by the Canadian Institute of Mining guidelines for resource reporting. Mineral resources do not demonstrate economic viability, and there is no certainty that these mineral resources will be converted into minable reserves once economic considerations are applied.
Assay values were verified against drill logs and assay certificates. Drill hole collar locations and downhole surveys were checked and verified. The mineral resource was estimated using 3.0-meter composites of the assay values.
A geological model was constructed of the Cu-Au-Ag-Mo mineralized zones. This model was used to constrain the composite values chosen for interpolation and the ore blocks reported in the mineral resource. A block model was constructed using 10-meter by 10-meter by 10-meter blocks in the x, y and z directions respectively. Grades for copper, gold, silver and molybdenum were interpolated into the blocks using ordinary kriging. A minimum of 3 and maximum of 20 composites were used to generate the block grades.
The indicated and inferred mineral resource estimates have been prepared in compliance with the standards of NI 43-101 by Jeff Choquette, P.E. of Hardrock Consulting LLC. Jeff Choquette acted as the qualified person, as defined in NI 43-101, and is independent of the Company and has reviewed the technical information in this release. A NI 43-101 report will be finalized and filed on SEDAR within 45 days of the date of this news release.
The Escalones property lies within the well-known central Chilean porphyry copper belt that runs north-south through Chile in the central Andes Mountains. The property is located approximately 100 kilometers southeast of Santiago and 35 kilometers due east of El Teniente, the world's largest underground copper mine.
The Escalones project hosts a four-square-kilometer area of hydrothermal alteration with coincident geophysical anomalies and additional skarn type geophysical targets extending a significant distance from this area. Significant grades of copper, gold and silver mineralization hosted in both skarn and porphyry. Mineralization remains open to further expansion laterally and at depth.

This news release uses the term 'inferred resources' which is recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects), however, such term is not a defined term under SEC Industry Guide 7 and is not normally permitted to be used in reports and registration statements filed with the United States Securities and Exchange Commission. Investors are cautioned not to assume that any part or all of the ‘inferred resources' will be upgraded or converted into ‘indicated resources' or ‘reserves' as defined under NI 43-101. In addition, 'inferred resources' have a great amount of uncertainty as to their existence, and economic and legal feasibility. Under Canadian rules, estimates of inferred resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for preliminary economic assessment as defined under NI 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
