News January 15, 2009 - Horne Smelter management announces that it is reducing its workforce and capital expenditures to strengthen its viability in current market conditions.  The decision comes after careful evaluation of the impact on the Horne operations of the closure of Fabie Bay Mine, a custom milling client, and a reduction in the volume of recycled feed. In total, 55 permanent operational positions associated with milling ore from Fabie Bay Mine and the recycling operation will be made redundant. In addition, the announcement will impact approximately 30 consultants and other contractors.  The challenging operating environment requires the Horne Smelter to scale back capital expenditures in 2009.  However, investments related to important environmental improvement projects will continue, including the CDN$5 million project to install a secondary hood to capture fugitive emissions and reduce arsenic concentrations in the ambient air in the Notre-Dame neighbourhood. 
“The smelting business has recently faced a challenging operating environment and it is important that we respond rapidly to this downturn in the market and make the necessary adjustments,” said Claude Bélanger, General Manager of the Horne Smelter.  “The Horne Smelter is a stand-alone custom smelting facility that operates in a very competitive environment. Full asset utilization and cost management are essential for Horne’s long-term viability.” said Mr. Bélanger.  “We will give our people the support they need to minimize the impacts of these measures on them as much as possible. A number will be transferred to other jobs in the smelter,” added Mr. Bélanger.
