Cambior: Update on the Drilling Program at the Westwood Project, East of the Doyon Mine-Best Result: 34.3 g Au/t, or 1 oz Au/t, Over 5 Meters With Copper and Silver Present.Business Editors LONGUEUIL, Quebec--(BUSINESS WIRE)--July 23, 2003 Cambior Inc. is pleased to announce the most recent results from the exploration drilling program which has been underway since November 2002 on the Westwood project, located two kilometers to the east of the Doyon mine and within the prolific Cadillac mining camp in northwestern Quebec. The work included the completion of the first drill hole to a linear depth of 2,272 meters, drill hole 1158-02, which intersected two mineralized min·er·al·ize v. min·er·al·ized, min·er·al·iz·ing, min·er·al·iz·es v.tr. 1.

The subsequent work included a secondary deviation secondary deviation n. The deviation of the healthy eye when an eye with a paralyzed muscle focuses on an object. ("wedge") carried out from the main hole 1158-02, starting at a depth of 1,160 meters. The geological context intersected is similar to that already described in the press release dated April 9, 2003. The secondary deviation 1158A-03 intersected the first mineralized zone between a depth of 1,791 and 1,829 meters (1,520 meters of vertical depth) approximately 100 meters to the east of the main hole. It corresponds to the extension of the Doyon Zone 1 and 2 corridor and consists of an intermediate tuff, strongly sericitized locally with disseminated disseminated /dis·sem·i·nat·ed/ (-sem´i-nat?ed) scattered; distributed over a considerable area. dis·sem·i·nat·ed adj.

Mentioned in: Rickets mineralization, n the bioprecipitation of an inorganic substance. . Some fine quartz veinlets with visible gold were noted. The second mineralized zone consists of the Westwood mineralized horizon and was intersected between a depth of 1,900 and 1,940 meters (1,570 meters of vertical depth), approximately 120 meters to the east of the main hole. The mineralization is comprised of multiple veinlets and centimetric bands of semi-massive pyrite pyrite (pī`rīt) or iron pyrites (pīrī`tēz, pə–, pī`rīts), pale brass-yellow mineral, the bisulfide of iron, FeS2. and chalcopyrite chalcopyrite (kăl'kəpī`rīt, kăl`kōpī'rīt) or copper pyrites (pīrī`tēz, pə–), brass-yellow mineral, sometimes with an iridescent tarnish. . Several bands enriched in sphalerite sphalerite (sfăl`ərīt, sfā`–), mineral composed of zinc sulfide, usually containing some iron and a little cadmium.

Our efforts have begun to bear fruit in this underexplored area to the east of the mine and at depth. These excellent results, in a very favourable geological context, encourage us to aggressively continue our exploration work Westwood area".

Ms. Bugnon is a qualified person (as defined by National Instrument 43-101) employed by Cambior for more than 6 years and with more than 23 years of experience in exploration.
