QUEBEC – AMERICAN BONANZA GOLD of Vancouver has outlined two new nickel-rich massive sulphide zones at its Fenelon project on the Detour Lake Break, 200 km north of Rouyn-Noranda. The best assay was 1.7% Ni over 0.5 m. Longer core intervals of 0.12% Ni over 22.4 m and 0.25% Ni over 14.2 m were also recorded.
According to American Bonanza, the Fenelon deposit is similar to the Kambalda nickel mines in Western Australia, where very significant nickel mining has taken place since the 1960s. At Kambalda, nickel is mined from 0.5- to 5-m-thick layers that are 100 to 300 m wide and up to 1,000 m long. Numerous economic nickel deposits occur at Kambalda in Archean ultramafic flows that consist of komatiitic (high-magnesium) basalt. High grade nickel at Kambalda generally grades over 1% and is usually contained within lower grade zones that are 10 to 30 m thick.
This description of the nickel occurrences at Kambalda is very similar to what has been observed at Fenelon, says the company. The nickel mineralization at Fenelon is contained in Archean komatiic basalts. The zones at Fenelon, while they remain open along strike and down dip, are of similar strike length to those at Kambalda.
More drilling, both up- and down-dip is planned. Follow progress at the Fenelon project, originally tested for its gold potential, at www.AmericanBonanza.com. The technical report dated Jan. 1, 2005, will be of interest.
