The investigations have shown that for a much reduced capital requirement of US$6 million, the capacity of the Mothae processing plant can be increased by ~45% to 1.6 Mtpa (215 tph).

With the addition of another parallel secondary crusher in due course, the capacity of the processing plant can be further increased to 1.8 Mtpa (250 tph).

The previous plan included an expansion to 300 tph, which is currently not being considered.

The plant design and capital costings have been provided by Consulmet in South Africa, who also designed and built the existing 1.1 Mt pa Mothae plant.
