Opening a new mine is an expensive, timeintensive process. Most mines must operate for years to cover initial startup costs; therefore, they are only opened after careful market analysis. In the case of the rare earth elements (REEs), there has only recently been a significant increase in REE usage, and the mining industry has not yet increased production to meet this demand.

A detailed mine design was created for four pits, R02N, R02S, R01N and R01S. These designs were completed to a short term planning level of detail which incorporated ramps to the coal floor for ten progressive strips. A total of seven coal seams of varying seam and interburden thickness were created in Excel® dipping NorthEast between 6% to 8%.

Underground mining is the oldest method of mining coal. From the late 1970s to early 1980s open pit operations increased, achieving high quantities of production and lower production costs. However, today, with environmental considerations and the greater depth of coal seam deposits, underground mining is proving to be the more viable alternative.
