Trial Operation Period From 22nd June 2015 to 28th July 2015

(37 days)

Soft Clay

• Total Volume to be handled = 3,000 m3/day (or 111,000 m3

for the whole trial period).

• Estimated to handle 300 truck loads of soft clay per day.

Good Earth

• Total Volume to be handled = 750 m3/day (or 27,750 m3 for

the whole trial period).• Estimated to handle 75 truck loads of good earth per day.
