Drilling Success Outside Of Pit Envelope At Wiluna
GWR Group Limited (ASX:GWR) has hit potential high-grade extensions up to 65% Fe in RC Drilling outside of the pit envelope at the Wiluna West Iron Ore C4 deposit in Western Australia.
The company has now received results from a recently completed 43 RC drill holes for 1,85 m infill drilling programme, designed as pre-production grade control over a strike length of 425 m within the proposed Stage 1 open pit of the Wiluna West Iron Ore C4 deposit.
Stage 1 relates to just 1 million tonnes of C4’s JORC 2004 Mineral Resource estimate of 21.6 million tonnes at 60.7% Fe an exceptional, DSO iron ore development project, which will produce a high grade, low impurity iron ore (comprising of 18.6 Mt at 61.2% Fe Indicated and 3.1 Mt @ 58.0% Inferred).
The pre-production, step-out and grade control drilling was undertaken over a strike length of 425 m at the proposed Stage 1 open pit of the C4 deposit where mining is due to commence in the first week of December 2020.
A total of eight RC holes for 238 m was completed up to 75 m to the south of the proposed Stage 1 development pit and based upon geological logging and assays confirmed high grade hematite mineralisation.
The high-grade mineralisation intersected by the step out drilling is not predicted in the current Resource model and represents a potential addition to the Stage 1 mining operation. GWR will look to follow up on this potential extension with further drilling
High-grade assay results received from this drilling campaign include 16 m @ 65.1% Fe from 14m and 30m @ 61.8% Fe from 6m.
In other news, Dynamic Drill and Blast Holdings Ltd (DDB:ASX) has been engaged to provide a production drill rig for blasting and provide blasting services and these operations are due to commence within seven days.
GWR is now updating the Resource model to a mining model, undertaking new pit optimisations, preparing final pit designs and scheduling of mining and first sales/shipment of ore.”
