Discussing operations near the SAG mill
Throughout 2005 the Lac des Iles Mill experienced
numerous setbacks in its operations. Production
totaled 177,167 ounces of palladium, compared to
308,931 in 2004. Ore processed in 2005 was
4,780,599 at an average palladium feed grade of 1.66 grams per tonne and an average palladium recovery of
69.6 %. Other metal production in 2005 included
18,833 ounces of platinum, 14,308 ounces of gold,
5,514,670 pounds of copper, and 2,353,227 pounds of nickel.
The lower production is primarily attributable to
issues the milling team faced with the ball mills,
chutes and transfers, and near the end of the year
problems with the primary crusher. These
equipment problems have since been addressed and the
mill is operating at historical levels.
