Westwood, Québec

Overview

LOCATION

The Westwood Project is located on the Doyon property, 2.5 kilometres east of the Doyon Gold Mine in the Bousquet Township, approximately 40 kilometres east of Rouyn-Noranda and 80 kilometres west of Val d’Or in southwestern Québec, Canada. This area is approximately 420km northeast of Montreal. The Westwood Project covers 1,925 hectares and consists of 120 titles, one mining lease, one surface lease and three tailings leases. The Westwood Project is held 100% by IAMGOLD.

The Doyon-Westwood property is accessible year-round via paved roads.

The 120 km separating Rouyn-Noranda from Val-d’Or is scattered with producing and past-producing mining projects such as: Mouska, Doyon, Bousquet, LaRonde and Lapa.

Communications are via fast network links and water supply facilities are available at the Doyon Gold Mine. These were extended to the Westwood Project in 2008. The nearest active railway line is located less than 10 km south of the project.



History

The first exploration activities reported in the Cadillac area date as far back as 1910.  During the 1930’s and 1940’s, development work was instigated by the Mooshla G.M. Company over the Mooshla-A and -B occurrences (4,444 tonnes of 27.0 g Au/t). In 1938 O’Leary Malartic G.M. Ltd developed the Westwood occurrence (surface works, shallow shaft and drifts) and the Mic Mac Mine produced a total of 723,400 tonnes at 4.6 g Au/t and 0.5% of copper between 1942 and 1947.

In 1972 the Doyon site became the co-property of Silverstack Mines Company Ltd and SOQUEM Inc., which carried out exploration between 1972 and 1975.  Long Lac Mineral Exploration Ltd (Lac Minerals Ltd) acquired Silverstack and a drilling program of 120 holes brought the deposit into production in February 1980. In 1983, a surface exploration campaign led to the discovery of Doyon West Zones.

In 1986, Cambior Inc. acquired SOQUEM’s mine assets, including 50% of the Doyon Mine.  Exploration programs were then conducted on Doyon from underground and on the Westwood-Warrenmac areas from surface.  In 1994, Barrick Gold Corp. acquired Lac Minerals assets and acquired its 50% interest in the Doyon mine. In January 1998, Cambior acquired Barrick’s 50% interest to become the sole owner.

In 2002, Cambior carried out a comprehensive geological compilation exercise that identified the favourable Bousquet Formation at depth as a priority target.  The first drilling phase was completed from surface in 2002 and resulted in the discovery of the Westwood and North Corridor mineralized zones at depth, on the eastern side of the Bousquet Fault.  This was followed by a five-year exploration program targeting the favourable Westwood corridor at depth. 

In November 2006, IAMGOLD Corporation acquired Cambior and all of its assets including the Doyon Division and Westwood Project.
