2. Mining Timetable
The following table (Table D -2) is a best estimate of the sequence of operations for the life of
the mine and is based on producing 104,000 raw tons per year and selling 100,000 tons per year.
Table D -2 Uncompahgre Pit Mining Sequence
The mining schedule is planned to minimize disturbance by reclaiming areas as additional
mining is undertaken. This table is based on a reasonable projection of average production rates,
which can vary significantly. If production and sales increase to 200,000 tons per year, the mine
life is shortened to 52.5 years. The table shows that mining and reclamation will occur
approximately 105 years and the total gravel sold will be approximately 11 million tons. The
large size of this operation allows for the operator to plan for the future as well as the County
Planning Department to know there is a long term source of material in this portion of Montrose
County.
