Osisko Brings First Half of Secondary Crusher Online


One of the two cone crushers has been installed at Osisko’s Canadian Malartic mill.
Canada’s newest intermediate gold produc-er Osisko Mining Corp. reported that con-struction and installation of the first of two cone crushers in the secondary crushing facility has been successfully completed. Commissioning of crusher No. 1 at the sec-ondary crushing facility is now under way. Crusher number two of the secondary crushing facility will be added upon arrival at site, which is still anticipated to be on schedule this coming June. A planned maintenance shut-down of the mill was also completed, with a liner change out in the SAG mill. The mill and the new sec-ondary crusher line have been started and are ramping up toward their target of 50,000 metric tons (mt) per day, as the manufacturer’s standard start-up test pro-tocols are being completed.

“The addition of the new cone crusher sets the stage for us to pursue the ramp up to 50,000 mt/d at the Canadian Malartic mill, which has a name plate design capac-ity of 55,000 mt/d,” said Osisko President and CEO Sean Roosen. “Construction and commissioning has gone very well with the mild winter we had on site. We want to congratulate the team including Osisko workers and contractors for completing the construction and installation ahead of schedule executing the build with no time lost accidents.”
