Silver Dragon Completes Positive Preliminary Feasibility Study on its Dadi Silver-Polymetallic ProjectToronto, September 7, 2011 (PRIME NEWSWIRE) – Silver Dragon Resources Inc. (OTCBB: SDRG) (the “Company”) is pleased to announce that a preliminary feasibility study has been completed for the Company’s Silver Polymetallic silver project located in Inner Mongolia, China in accordance with Canadian Securities Administrators National Instrument 43-101 Standards of Disclosure for Mineral Projects.
The economic analysis estimates that at a 40 g/t cut-off grade, the Dadi project will generate net cash flows over the seven-year project life of US $207 million, of which US $82 million will accrue to the Company. The report estimates an internal rate of return (IRR) of 175% and a net present value (NPV) of US $142 million applying an 8% discount rate. Based upon the Company’s 40% interest in the project, the IRR is 153% and NPV is $55 million. These figures are based on mineral resources and not on mineral reserves. The economic analysis included was based on measured and indicated resources. Inferred resources were not included in the economic analysis.
The report estimates the operating costs for the project at US $11.50 per metric tonne of ore processed and the capital costs to bring the mine into production have been estimated at US $13 million.
The key assumptions used in the estimates include a three-year average market price of $21/oz for silver and market price of US $0.96/lb for zinc and US$1.00/lb for lead. Key assumptions also include 20% dilution, 70% mining recovery and 40% cut-off grade. Metallurgical studies indicate 90% of the lead and 40% of the silver will be contained in the lead concentrate and 75% of the zinc and 40% of the silver will be contained in the zinc concentrate. The average grade of the lead concentrate is 66% lead and 2,670 g/t silver. The average grade of the zinc concentrate is 42% zinc and 31 g/t silver.
Marc Hazout, President and CEO of the Company stated: “As we move towards completing the permitting and preparing for production at Dadi, this updated study demonstrates the economic potential of the project. I am extremely pleased with the quality of the project as it is presently defined, as well as the future growth potential.”
The study includes an NI 43-101 compliant resource estimation and model study to test the resource estimation. The resource estimation was calculated using a modified polygonal method incorporating cut-off grades of 1g/t silver and 40g/t silver. The following tables summarize the resource estimate.
|Cut-off > 1g/t AG||Tonnes||Silver (g/t)||Lead %||Zinc %|
|Measured + Indicated||2,732,500||192.76||1.94||2.81|
|Cut-off > 40g/t AG||Tonnes||Silver (g/t)||Lead %||Zinc %|
|Measured + Indicated||1,856,900||276.29||2.74||3.25|
The cut-off grade was determined solely on the basis of the silver grade. Metal equivalents were not used. The resource estimate supporting the economic analysis does not include inferred resources.

Cautionary Note on Mineral Reserve and Resource Estimates:
Silver Dragon Resources Inc. is a U.S. company that files reports with the United States Securities and Exchange Commission (the “SEC”). Information regarding mineralization and reserves included in the Company’s reports with the SEC are generally required to comply with the SEC’s Industry Guide 7. This press release and the study do not comply with Guide 7, because they were prepared in accordance with Canadian Institute of Mining, Metallurgy and Petroleum Standards, which have been adopted by NI 43-101 --. Accordingly, we caution you that the information contained in this press release and may not be comparable to information included in the Company’s SEC reports, and similar information made public by other U.S. companies under the United States federal securities laws and the rules and regulations thereunder. In particular, the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” as used in this press release and the study are defined in and required to be disclosed by NI 43-101; however, these terms are not defined in 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 mineral deposits in these categories will ever be converted into mineral reserves with demonstrated economic viability. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and great uncertainty 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. 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.
