This temporary shutdown of the semi-autogenous grinding (SAG) mill was scheduled for the fourth quarter to perform planned upgrades, but due to a recent mechanical problem, the upgrade was moved forward. The mill upgrades consist of replacing the gear box, bull gear, pinion gear and sole plate. All new parts are onsite at Nye, with the exception of the sole plate, and it is expected by September 11, 2000. Bill Nettles, Chairman and CEO, said, ``Our plan is to have the SAG mill back in operation within 10 to 14 days. Currently, we have about 20,000 tons of ore stockpiled and this will increase, but is expected to be worked off by the end of the fourth quarter. In addition, we have put a contingency plan in place to bypass the SAG mill using an existing crushing plant supplied by a contractor. This auxiliary crusher will enable the concentration circuit to run at a reduced rate until the upgrades are completed. The mining operation will continue as usual.'' He added, ``We continue to be pleased with the progress being made at the Stillwater Mine. We were on track to show improved results for the third quarter with ore tons mined per day up 11% for the first two months of the quarter compared to the second quarter and development footage at record levels. However, with the temporary shutdown, ounces produced for the third quarter are expected to be slightly below second quarter.''
