MINING TIMETABLES
This estimated mining timetable is based on an average year,
and L.G. Everist expects some years to vary widely from the
average. If there are changes in the mining timetable, we will
discuss the reasons for the change in the annual report that
follows the change and modify it at that time if needed.
