South American Silver Files International Arbitration

VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 30, 2013) - South American Silver Corp. (TSX:SAC)(OTCQX:SOHAF) announced today that its wholly-owned subsidiary, South American Silver Limited ("South American Silver"), has commenced international arbitration proceedings against the government of Bolivia ("Bolivia" or the "Government") under the Arbitration Rules of the United Nations Commission on International Trade Law (UNCITRAL) pursuant to the Agreement between the Government of the United Kingdom and the Government of Bolivia for the Promotion and Protection of Investments (the "Treaty").

The arbitration has been commenced as a result of acts and omissions of the Government including the issuance of Supreme Decree No.1308 on August 1, 2012 (the "Decree"). The Decree revoked mining concessions covering the Malku Khota Mining Project (the "Project") held by Compañia Minera Malku Khota S.A. (CMMK), a wholly-owned subsidiary of South American Silver Limited. These measures resulted in the complete expropriation of the Project without compensation. The arbitration claim is for Bolivia's breach of the Treaty and international law. Bolivia has breached the Treaty's requirement to provide full protection and security to foreign investors and their investments, as well as the Treaty's protections against, among other things, expropriation without just and effective compensation, unfair and inequitable treatment, and less favorable treatment than afforded to Bolivian nationals or nationals of third states.

Since the Decree, the company has made numerous attempts to open a dialogue with the Government with the aim of reaching an amicable resolution of the dispute, including receiving fair-value compensation. In late February 2013, the company was invited to attend a meeting set for 17th April, 2013 in La Paz, Bolivia. Attorneys representing South American Silver attended the April meeting but no resolution was reached and no compensation offered. The Decree stated clearly that the Bolivian state mining company, Corporación Minera de Bolivia (COMIBOL), would hire an independent firm to carry out a valuation of the investments made by CMMK within a period not to exceed one hundred and twenty (120) business days. However, no such valuation has been carried out, nor has an independent firm been hired to undertake the valuation.

Exploration commenced at Malku Khota in 2003 and work on the Project continued through the expropriation in August 2012. After completing a total of 42,700 meters of drilling in 121 diamond core holes, and undertaking metallurgical testwork, process development and engineering design, a Preliminary Economic Assessment (PEA) Update was filed on SEDAR on 13th May, 2011 in a NI 43-101 technical report (News Release NR 11-06 dated 16th May, 2011). The May 2011 PEA Update included economic modeling that indicated pre-tax net present value (NPV) at a 5% discount rate of:

• $704 million at metal prices of $18.00/oz silver and $500/kg indium
• $1.482 billion at $25.00/oz silver and $570/kg indium
• $2.571 billion at the $35.00/oz silver and $650/kg indium. ⁽¹⁾

After the 2011 PEA Update, the pre-feasibility study (PFS) phase was started in June 2011. The ongoing work program, which was designed to expand mineral resources and enhance project economics, included the development of social and community programs to benefit indigenous communities, baseline studies for the environmental review and assessment program, exploration, metallurgical testwork, flowsheet development, engineering design and preparations to construct a modern 150 person exploration camp near the exploration site. The planned work programs including the PFS were not completed due to the expropriation.

Phillip Brodie-Hall, President and CEO of South American Silver said, "It is regrettable that we are forced to resort to international arbitration to resolve this matter. Bolivia chose to expropriate our mining concessions; it must now meet its legal obligations and compensate us for this significant loss. International arbitration gives us the means to pursue our case and we are very confident that it will deliver fair value compensation. We have a first-class team working on the case and, while we are open to dialogue with the Government, we are prepared to go the full distance in arbitration if that's what it will take to get fair value compensation. Our loyal shareholders deserve nothing less."

Now that the arbitration has been commenced, the Bolivian Government has thirty days to respond and an arbitration tribunal will be empanelled in the coming months. Thereafter, the tribunal will set a provisional timetable for the arbitration itself including a schedule for submission of a Statement of Claim, Statement of Defense and oral hearings. Unless there is a negotiated settlement of the dispute, it is expected that the arbitration could take up to 2-3 years from commencement of proceedings until rendering of a final award.

Bolivia has been involved in over fifteen "nationalizations", the majority of which have taken place after President Morales came to office. A number of the cases have reached negotiated settlements and at least five others are pending. Bolivia's reserves of cash and gold were estimated at $13.62 billion as of December 31, 2012, up from US$3 billion when Morales came to office in 2006. Bolivia's credit rating was upgraded by all three major rating agencies in 2012, the most recent being Fitch Ratings upgrade from B+ to BB- in October 2012. Bolivia has demonstrated that it has ready access to international funding, having had a $500 million 10-year bond offering significantly oversubscribed in August 2012 at an interest rate of only 4.875%. The IMF recently forecast that Bolivia will be one of the fastest growing economies in South America with an expected GDP growth rate in 2013 of 4.8%.

Mr. Brodie-Hall went on to say, "It is not a question of whether Bolivia is capable of meeting its obligation to compensate the company for the expropriation; it clearly has the financial capacity."

It was not prepared to be used as a valuation of the Project nor should it be considered to be a final feasibility study on which a commercial production decision could be made. The criteria, methods and estimates were preliminary and involved a high level of subjective judgment. Factors that could cause results or events to differ materially from current expectations expressed or implied by the forward-looking statements, include, but are not limited to risks of the mineral exploration industry which may affect the advancement of the Escalones project; availability of sufficient financing to fund further required work in a timely manner and on acceptable terms; the political and economic climate in Bolivia including the attitudes and actions of the Bolivian government related to foreign investment in Bolivia and the response of the Bolivian government to the filing of the Notice of Arbitration; the advancement of the international arbitration process in a customary manner; the outcome of the international arbitration process; and other risks more fully described in the Company's Annual Information Form filed and publicly available on SEDAR at www.sedar.com .
