Silver Wheaton Announces Closing of the Early Deposit Precious Metals Purchase Agreement with Panoro Minerals


VANCOUVER, March 21, 2016 /CNW/ - Silver Wheaton Corp. ("Silver Wheaton" or the "Company") (TSX:SLW) (NYSE: SLW) is pleased to announce that its wholly-owned subsidiary, Silver Wheaton (Caymans) Ltd. ("SWC"), has entered into a definitive Early Deposit Precious Metals Purchase Agreement (the "Cotabambas Early Deposit Agreement") with Panoro Minerals Ltd. and its wholly owned subsidiary Panoro Trading (Cayman) Ltd. ("Panoro") in respect of the Cotabambas project located in Peru.

SWC will be entitled to purchase 100% of the silver production and 25% of the gold production from the Cotabambas project until 90 million silver equivalent ounces attributable to SWC have been delivered, at which point the stream would drop to 66.67% of silver production and 16.67% of gold production for the life of mine. Under the Cotabambas Early Deposit Agreement, SWC will pay a total cash consideration of US$140 million plus an ongoing production payment of the lesser of: i) US$5.90 for each silver ounce and US$450 for each gold ounce (both subject to a 1% annual inflation adjustment starting in the fourth year after the completion test is satisfied) and ii) the prevailing market price. Once certain conditions have been met, SWC will advance US$14 million to Panoro, spread over up to nine years. In 2016, SWC anticipates making advanced payments of between US$2 million and US$4 million to Panoro. Following the delivery of a bankable definitive feasibility study, environmental study and impact assessment, and other related documents (collectively, the "Feasibility Documentation"), and receipt of permits and construction commencing, SWC may then advance the remaining deposit or elect to terminate the Cotabambas Early Deposit Agreement. If SWC elects to terminate, SWC will be entitled to a return of the portion of the US$14 million paid less US$2 million payable upon certain triggering events occurring. Until January 1, 2020, Panoro has a one-time option to repurchase 50% of the precious metals stream on a change in control for an amount based on a calculated rate of return for SWC.


The Cotabambas Copper-Gold-Silver Deposit is located in Peru, South America, and has been systematically explored since 1995. As stated in the report titled "Cotabambas Project, Apurimac, Peru, NI 43-101 Technical Report on Updated Preliminary Economic Assessment", dated September 22, 2015 (the "updated PEA"), the Cotabambas project has Indicated Mineral Resources of 117.1 million tonnes at average grades of 0.42% Cu, 0.23 g/t Au, and 2.74 g/t Ag comprising contained metal of 1.09 billion pounds of copper, 0.86 million ounces of gold, and 10.3 million ounces of silver. In addition, Inferred Mineral Resources total 605.3 million tonnes at average grades of 0.31% Cu, 0.17 g/t Au, and 2.33 g/t Ag comprising contained metal of 4.16 billion pounds of copper, 3.38 million ounces of gold, and 45.37 million ounces of silver.1

The updated PEA envisions a nominal processing throughput of 80,000 tpd of oxide, mixed and sulphide mineralization in a conventional copper porphyry flotation concentrator will produce about 270 ktpa of copper, gold and silver concentrate with copper as the main payable metal. Over the 17-year mine life, estimated payable metal is approximately 2.6 billion pounds copper, 1.6 million ounces of gold, and 17.3 million ounces of silver produced at a cash cost of US$1.22/lb copper (C1), net direct after secondary metal credits.

The currently defined Mineral Resources exist within the Ccalla and Azulccacca deposits. Significant exploration potential may exist within the Maria Jose target immediately to the northeast of Ccalla and Azulccacca as well as the Jean Louis target located to the southwest. Further potential may exist on parallel trends within the Guaclle-Buenavista, Ccarayoc, Chuyllullo, Chaupec and Añarqui targets. All of these targets are within Panoro's current exploration concessions, and are also to be contained within the area of interest for this proposed Early Deposit Agreement.

Mr. Neil Burns, Vice President, Technical Services for Silver Wheaton, is a "qualified person" as such term is defined under National Instrument 43-101, and has reviewed and approved the technical information including information on mineral resources disclosed in this news release.  

1 Source for Mineral Resource estimates is the updated PEA and a press release issued by Panoro on September 22, 2015. The updated PEA was prepared by Amec Foster Wheeler Americas Ltd. and Moose Mountain Technical Services Ltd. and is considered preliminary in nature. It includes Inferred Mineral Resources that are considered too speculative to have the economic considerations applied that would enable classification as Mineral Reserves. There is no certainty that the conclusions within the updated PEA will be realized.

2 Silver equivalent production forecast assumes a gold/silver ratio of 80:1. Please see "Cautionary Note Regarding Forward-Looking Statements" for material risks, assumptions and important disclosure associated with this information.

CAUTIONARY NOTE TO UNITED STATES INVESTORS REGARDING PRESENTATION OF MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES: The information contained herein has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. The terms "mineral reserve", "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms defined in accordance with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Standards"). These definitions differ from the definitions in Industry Guide 7 ("SEC Industry Guide 7") under the U.S. Securities Act of 1933, as amended (the "U.S. Securities Act"). Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Also, under SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. In addition, the terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence and as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures. Accordingly, information contained herein that describes the Company's mineral deposits may not be comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder. United States investors are urged to consider closely the disclosure in the Annual Information Form, a copy of which is available at

In accordance with the Company's MD&A and financial statements, reference to the Company includes the Company's wholly owned subsidiaries.
