Start of blasting on phase 3 togetherwith other shots when ready

Minimum 4 shifts for each fleet to stay

in one location

Push dirt over if the rock on phase 3 is

too small for diggingStart building haul access to top of

phase 3Survey should have boundary line inplace for phase 3 and maintain it

start drilling on top of phase 3 onceaccess is built and when having extracapacity

when direct feeding or crusher is forservice, loader can do clean-ups in thepit with 2 trucks

sequencing for each location is notcritical but the total movement once iscoal is accessible
