The other thing , the equipment is similar to what EUA have at WK, think they have more dumper trucks though.
Mining
Mining methods will employ conventional open pit, truck and shovel operating practice. Three pits will be mined over the 13-year mine life, with an additional two years of pre-production mining to be undertaken where waste material is being mined for construction and ore stockpiled ahead of processing plant commissioning. The mining equipment fleet is to be owner-operated and will include outsourcing of certain support activities such as explosives manufacturing and blasting. Production drilling and mining operations will take place on a 10 m bench height. The primary loading equipment will consist of two hydraulic face shovels (29 m3 bucket size) and one large front-end wheel loader (30 m3 bucket size). The loading fleet is matched with a fleet of 13 x 216 tonnes haulage trucks. A fleet of two 90 tonnes excavators will be used to excavate the limited volume of overburden material and will also be allocated to mining of the narrow-thickness ore zones associated with the W-Horizon in the South Pit to mitigate additional dilution.
