American Bonanza Corporate Update

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 19, 2007) - American Bonanza Gold Corp. (TSX:BZA)(PINK SHEETS:ABGFF)(FRANKFURT:AB2) ("Bonanza") reports significant 2007 developments at several projects following its triple objective strategy to increase shareholder value.

- Objective 1: Achieve production - Two major gold discoveries have been made at the high grade Copperstone project, where mine planning studies will likely further improve due to the addition of high grade mineralization to the resource base. More drilling is planned soon to follow-up these exciting new gold zones. The recently signed agreement with Agnico-Eagle to jointly develop the Northway and Vezza properties represents a second high priority project with near term production potential. Drilling is planned for late 2007 to expand the high grade portions of the Northway project.

- Objective 2: Discovery through exploration - Successful results at the Fenelon Nickel project, the La Martienere gold project and the Northshore gold project. These projects hold significant potential and are showing excellent results. Additional drilling is planned at these three projects, and the first resource estimate for La Martienere will begin to quantify the 1.3 kilometer long gold zone at the project.

- Objective 3: Market assets where benefits to the Company's treasury will ameliorate the need for future dilution. The Taurus project was sold on excellent terms: up to $11 million plus 3 million shares of Cusac Gold Mines. The Northway Joint Venture also limits exploration expenditures. Several other projects are being considered for Joint Venture or marketing to new partner companies.

Through 2007, Bonanza has continued to aggressively develop its exciting projects in the mission to become a high grade gold producer based in stable areas of Canada and the United States. So far in 2007, Bonanza has drilled a total of over 22,000 meters in pursuit of its strategy to develop mines while discovering new deposits.
