Gryphon Gold Corporation: Positive Pre-Feasibility Study Filed for Borealis Oxide Project in Nevada

RENO, NEVADA--(Marketwire - Sept. 21, 2009) - Gryphon Gold Corporation (TSX:GGN)(OTCBB:GYPH) (the "Company") announced on August 28, 2009 that a copy of the full Pre-Feasibility Study for the Borealis Oxide Project had been filed on the SEDAR website. The Company restated the Pre Feasibility Study as of September 21, 2009 to clarify the description of reserves attributable to Borealis Oxide Project. The restated study has been filed on the SEDAR website,

The NI 43-101 compliant study, completed by Telesto Nevada Inc in mid-July of 2009 (as restated September 21, 2009), examined the proposed, low-cost open-pit mine at the Company's wholly owned project located in the Walker Lane Belt of western Nevada. Highlights are as follows:

Average annual production over 50,000 oz gold-equivalent

Low initial construction cost of US$14.8 million using a 10% contingency

Average life-of-mine cash operating cost of US$476 per oz gold

After-tax NPV of US$12.5 million, IRR of 27% and payback of 2.25 years based on a US$800 per ounce price of gold

The Pre-Feasibility Report for the Borealis Oxide Project shows a change in classification of mineralization from the measured and indicated resource categories in previous NI 43-101 resource estimates(1) to reserves. The proven and probable reserves of 377,356 oz of gold(1) gives the Borealis Project an estimated five-year mine life with average annual production of more than 50,000 gold-equivalent ounces, including recovered silver ounces.

No inferred resources were included in the study. The inferred oxide resources (totaling 350,706 oz of gold)(1) represent potential to extend the mine life beyond the five-year plan examined in the Pre-Feasibility Study, if such inferred resources are confirmed as reserves as a result of additional exploration work. Ongoing exploration also provides opportunities for further resource expansion as the Borealis Property covers approximately 27.5 square miles of favorable Nevada geology.


Gryphon Gold is a Nevada-focused gold exploration and potentially a production company. Its principal gold resource, the 1.4 million ounce (377,356 ounces of proven and probable reserves and 1,022,644 ounces of measured and indicated) and 1.1 million ounce (inferred) Borealis deposits, is located in the Walker Lane gold belt of western Nevada. The Borealis gold system is one of the largest known volcanic-hosted high-sulphidation gold bearing mineralized systems in Nevada. Nevada Eagle Resources, a wholly owned subsidiary, has approximately 60 highly prospective gold properties located in desirable gold trends in Nevada. Nevada Eagle's Golden Arrow property (leased to Nevada Sunrise Gold Corp.) contains a NI 43-101 compliant resource of 296,500 ounces of gold (measured and indicated1) and 50,400 inferred ounces of gold1. Nevada Eagle's other principal properties have a cumulative 550,000 of historical ounces of gold (the historical estimates are based on internal reports prepared by prior owners prior to February, 2001, and were not prepared in accordance with CIM NI 43-101 standards, and thus their reliability has not been verified). A number of Nevada Eagle's principal properties are subject to joint venture or farm-in agreements in favor of third parties.

(1)Cautionary Note to U.S. Investors concerning estimates of Reserves and Measured, Indicated and Inferred Resources: This press release and the Pre-Feasibility Study referenced in this press release use the terms "proven and probable reserves", "Measured Resources", "Indicated Resources", "Measured & Indicated Resources" and "Inferred Resources" as defined under NI 43-101. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosures an issuer makes of scientific and technical information concerning mineral projects. We advise U.S. investors that while these terms are defined in and required by Canadian regulations, these terms are not defined terms under the U.S. Securities and Exchange Commission ("SEC") Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. "Measured Resources", "Indicated Resources", "Measured & Indicated Resources" and "Inferred Resources" are not recognized under SEC Industry Guide 7. "Inferred 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 a feasibility study or pre-feasibility study, except in rare cases. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant "reserves" as in-place tonnage and grade without reference to unit measures. 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. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves.

This press release contains "forward-looking statements" and "forward-looking information" within the meaning of Canadian and United States securities laws, which may include, but is not limited to, statements with respect to projections and expectations related to the results and projections contained in the pre-feasibility study regarding the Borealis resource, including, the expected mine life, recovery, capital costs, cash operating costs and other costs and anticipated production of the described open-pit oxide heap leach mine at the Borealis property, anticipated internal rate of return, anticipated payback period, availability of capital for development and the affect of the pre-feasibility study on the company's ability to raise capital for development, sensitivity to metal prices and ore grade, resource estimates on the Borealis resource, pediment exploration plans and other plans, projections, estimates and expectations. Such forward-looking statements and forward-looking information reflect our current views with respect to future events and are subject to certain risks, uncertainties and assumptions, including, the risks and uncertainties outlined under the section headings "Forward-Looking Statements" and "Risks Factors" in our annual report on Form 10-KSB, as filed with the SEC on June 26, 2009, under the section heading "Risk Factors" in our most recent quarterly report on Form 10-Q, as filed with the SEC on February 13, 2009, as amended March 10, 2009, and in our most recent financial statements, reports and registration statements filed with the SEC (available at and with Canadian securities administrators (available at ). In addition, the pre-feasibility study uses an estimate of metal prices based on historical and future metal prices. The operating and capital costs in the pre- feasibility study were developed to be reasonable estimates within industry benchmarks. There is no certainty that the results of the pre-feasibility study will ever be realized. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, believed, estimated or expected. We do not undertake to update forward-looking statements or forward-looking information, except as may be required by law.
