Gryphon Feasibility Study to be Revised

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 27, 2006) - Gryphon Gold (TSX:GGN)(OTCBB:GYPH) today announced that the Company will be revising the previously reported Borealis Feasibility Study and the related 43-101 Technical Report (August 17, 2006).

Following reviews of the resource model and mine planning the Company has determined that revisions are required due to miscalculations made in the reserve and resource calculations contained in the Feasibility Study for the Borealis heap leach mine.

Although the total gold resources estimates for the Borealis property are expected to be down nominally (as illustrated below), the impact of the anticipated reduction in recoverable gold and silver estimates on the Borealis heap leach mine will necessitate postponing the Company's plan to raise production financing. The Company will delay its decision to place the heap leach mine into production until a reassessment of the viability of the heap leach mine is completed.

The total preliminary gold and silver resource estimates for the Borealis property are anticipated to be revised as follows:

(i) The revised resource information as at November 27, 2006 is preliminary and is subject to confirmation in the revised Technical Report the Company will be filing with Canadian securities regulatory authorities.

It is estimated that the recoverable gold included in the feasibility study's reserves (for the Borealis heap leach mine's portion of the company's gold and silver resources) may be reduced by as much as 85,000 ounces (to 212,000 from 297,000 ounces) and recoverable silver may be reduced by as much as 1.4 million ounces (to 1.5 million from 2.9 million ounces).

"We are initiating an independent review to determine the exact net effect of these changes. The necessary steps will be taken to ensure precision in the revised report", said Albert Matter, Chairman of Gryphon Gold.

While the Company is postponing the production financing of the heap leach mine pending the reassessment, the Company will focus on the continuing exploration of the highly prospective Graben sulphide deposit and its district targets. The Company will be reporting on its exploration programs once all the assays have been completed and analyzed which is expected by mid-December.
