American Bonanza Increases Interest in Northway to 100%

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Jan. 15, 2007) - American Bonanza Gold Corp. (TSX:BZA)(FWB:AB2) ("Bonanza") is pleased to announce that it has acquired a further 25% interest in the Northway Project, increasing its interest from 75% to 100%. The current acquisition of the final 25% interest in the Northway project is a result of Bonanza's strategy to acquire advanced stage gold properties in mining friendly areas of Canada and the western United States. Bonanza continues to drill its portfolio of high grade gold properties. The current acquisition complements Bonanza's gold assets and increases the Corporation's total gold resources by over 215,000 ounces. These ounces are historical in nature and are not National Instrument 43-101 compliant.

The Northway property is located in Quebec, 25 kilometers south of Matagami and covers 3,600 hectares. The Northway property lies one kilometer along strike to the east of Agnico Eagle's Vezza deposit and may be a continuation of the same gold zone. As previously reported by Agnico-Eagle Mines Ltd., the Vezza deposit is estimated to contain a historical resource of 2.76 million tons grading 0.136 ounces of gold per ton (375,000 contained ounces of gold).

On the basis of the current acquisition Bonanza controls 100% of the Northway property, which contains a historic resource of 18.2 million tonnes grading 1.48 grams per tonne gold, containing 866,000 ounces of gold. Within this resource, significant higher grade zones are present. The resource remains open to expansion along strike and down dip in several areas.

Bonanza plans an estimated 5,000 meters of Phase I drilling in 25 drill holes along the Northway gold zone planned to commence in first half of this year. The Phase I drilling program will focus on resource expansion and confirmation of the high grade zones. Following completion of Phase I drilling, a Phase II drilling program will support development of a National Instrument 43-101 compliant resource estimate.

Brian Kirwin, Chief Executive Officer stated, "This acquisition and resulting addition to the Bonanza's total gold resources is a further step in accomplishing the Corporation's Mission of becoming a high grade gold producer based in stable areas of Canada and the United States."

The following is an updated summary of gold resources controlled by the Company which reflects the additional historical ounces acquired at Northway.
