ROUYN-NORANDA, Que. Drilling at the Westwood project, 2 km east of CAMBIOR’s Doyon gold mine, has intersected zones of semi-massive sulphide mineralization. Cambior began a five-year, $20-million strategic exploration plan in the area in 2001. Drill hole 1158-02, begun last November, intersected a sequence of volcanic rocks in the southern portion of the Blake River Group, in particular the Bousquet Formation. This formation hosts the majority of the known gold and base metal orebodies in the Doyon-Bousquet-LaRonde camp, from which 20 million oz of gold has been or could be recovered.

Significant results from hole 1158-02 include: 39.3 g/t Au over 0.6 m and 11.8 g/t Au and 0.24% Cu over 3.5 m in the extension of a stratigraphic horizon containing Doyon zones 1 and 2; 4.2 g/t Au and 0.14% Cu over 9.5 m, including 6.0 g/t Au and 0.98% Cu over 4.0 m in the northern portion of the Westwood horizon; and 3.4 g/t Au and 0.38% Cu over 15.2 m, including 5.5 g/t Au and 0.58% Cu over 5.2 m in the southern portion of the Westwood horizon.

Two mineralized sectors have been intersected. One is comprised of an intermediate tuff that is locally strongly sericitized and mineralized in disseminated sulphides with several fine quartz veinlets and occasional visible gold. The second is composed of multiple veinlets and centimetric bands of semi-massive pyrite and chalcopyrite hosted in a strongly altered dacitic unit. Cambior says the alteration is typical of certain lenses found in the Bousquet and LaRonde mines.

Go to Cambior and find the press releases in the Investor Relations area to view a longitudinal section of the Doyon mine and Westwood project. Cambior’s gold production target for 2003 is 522,000 oz at a mine operating cost of US$227/oz.
