August 31, 2005 - American Bonanza Gold Corp. (TSX: BZA) (“Bonanza”) is pleased to announce that a drill rig is being mobilized to the company’s 100% owned Gold Bar property on the southern portion of the Cortez Trend in Nevada. The Gold Bar property is located on the prolific Battle Mountain/ Eureka mineral belt 28 miles southeast of the Placer Dome’s (over) 10 million ounce Cortez Hills/ Pediment discovery and 11 miles south of the Tonkin Springs Gold Mine owned by US Gold Corp., which recently appointed Rob McEwen as CEO and Chairman of the Board.
Phase 1 of the Gold Bar drill program will consist of 8 to 10 reverse circulation drill holes testing the feeder extensions of the Mill Site deposit and the East target. Mineralization is hosted in the Devonian Denay Formation, the same host as the original Gold Bar Pit. Mining from 1987 to 1994 at the Gold Bar Mine complex resulted in a total of 485,000 ounces being produced, as has been previously announced.
The Mill Site deposit is 1,500 feet west of the Gold Bar pit and is thought to be the faulted northern extension of the Gold Bar pit mineralization. The East target is located down dip, 400 feet east of the bottom of the Gold Bar pit. The target zones are thought to be parallel structures to the main Gold Bar feeder fault – the primary “plumbing” for gold-bearing fluids during the formation of the Gold Bar gold deposits.
Brian Kirwin, President and CEO, commented, “With our Copperstone Project now in the Pre-Feasibility study stage, and an aggressive exploration program underway at the Fenelon Gold Project, we are moving forward to drill the Gold Bar Project. The property covers very prospective ground on a major Nevada Gold Belt and we are very excited to begin drilling these targets.” Mr. Gregory French, CPGeol., a Qualified Person as defined in Canadian National Instrument 43-101, is responsible for the design and quality control of the drill program.
