Silverado: Clarification & Retraction News Release Nolan Creek Sb-Au Project Amended NI 43-101F1 Report

SURREY, BRITISH COLUMBIA--(Marketwire - July 26, 2011) - Silverado Gold Mines Ltd. (OTCBB:SLGLF)(FRANKFURT:SLGL) (www.silverado.com) (the "Company" or "Silverado") - The British Columbia Securities Commission (BCSC) has been working with Silverado since its January, 2011 Cease Trade Order in British Columbia. As a result, the Company has filed an amended Nolan Creek Technical Report, dated July 9, 2011, on SEDAR. The Company also retracts the following additional resource estimates, reserve estimates, and economic analyses, derived from third party reports and related news releases, which it previously disclosed at its Nolan Creek Project and which the amended technical report does not support.

RETRACTION OF ADDITIONAL NOLAN CREEK ESTIMATES AND ANALYSIS

The Company's website included a press release dated May 13, 2010 incorporating a direct link to a third party report by Murphy Analytics also dated May 13, 2010 (the Murphy Report). A Qualified Person did not prepare the Murphy Report, which disclosed an economic analysis using a quantity exceeding that used in the technical report. The economic analysis in the Murphy Report was potentially misleading and not complaint with NI 43-101.

The Company's January 11, 2011 news release provided a direct link to a "Report on the Nolan Gold and Antimony Mine" dated January, 2011 (the January 2011 Report). The January 2011 Report disclosed non-compliant and potentially misleading resource and reserve estimates not prepared by a Qualified Person, and not supported by a technical report. The January 2011 Report included:

  • reserve estimates with much larger tonnage than supported by a technical report
  • reserves with average gold and antimony grades much higher than supported by the project data and any technical report
  • prohibited economic analysis of the large hypothetical resource quantities and grades
  • additional non-compliant potential exploration targets not supported by a technical report
  • prohibited economic analysis of non-compliant potential exploration targets

The Company retracts information about estimates of potential exploration targets, resources, reserves, and economic analysis in the 2010 Murphy Report and the January 2011 Report, and has removed these reports from its website.

The Company's news releases of August 31, 2010 and September 1, 2010 disclosed a large volume target at Pringle Bench on the Nolan Property, with average 35 foot width, that was not compliant with NI 43-101 disclosure requirements for a potential exploration target, and is unsupported by a technical report. NI 43-101 requires information about potential exploration targets to disclose the basis for potential quantity and grade ranges, and include specific cautionary language. The Company's disclosure did not meet these requirements and the Company clarifies that it has not received any estimates of potential exploration targets, as defined by NI 43-101, at Nolan Creek. In particular, the information about potential lode exploration targets at Pringle Bench in the September 1, 2010 news release was not compliant with NI 43-101 and potentially misleading, and the Company retracts the dimensions of the Pringle Bench target and any implication of potential economic grade of that target.

Because of the above concerns, the BCSC issued a Cease Trade Order (CTO) on January 21, 2011. In response, the Company filed an amended NI 43-101F1 Technical Report on SEDAR on July 9, 2011. The Company now intends to apply for revocation of the CTO in British Columbia.

NEW NOLAN CREEK TECHNICAL REPORT FILED ON SEDAR

The new Nolan Creek Report filed on July 9, 2011 includes minor updates to the resource estimates, expands disclosure about economic analysis and mining methods, and adds cautionary language regarding mining dilution.

The methods of ascertaining calculations of Indicated and Inferred Resources of gold (Au) and antimony (Sb) on the Nolan Project were accomplished using the Polygonal Method. After discussion with the BCSC, the QP compared estimates from a selected portion of the mineralized zone that used the polygonal estimation method with resource estimates calculated from the same zone using a computer-generated, Vulcan™ block modeling method. The results show that indicated resources as calculated using the polygonal method compare within a few percent of resources determined by the computer-generated block model approach. The conclusion reached by the QP therefore is that the polygonal resource estimation method selected for this study is valid. No new probable reserve estimates were released. The probable reserve estimates are the same as reported in a NI43-101 Report authored by the QP and released by Silverado in June, 2009, and there have been minor changes to the resource estimates.

The new lode Mineral Reserve and amended Resource Calculations for Workman's and Pringle Bench on the Nolan Antimony (Sb)-Gold (Au) property in the Koyukuk District of Alaska is as follows:

Cautionary Note to U.S. Investors Concerning Estimates of Probable Reserves: Readers are cautioned that the above estimates are under the category of a probable reserve and they are not a proven reserve. These values are based on the results of preliminary feasibility study, which is not the same as a complete feasibility study.
