In Stage 1 of operations, up to 400,000 tonnes of ore will be crushed and screened from these areas to produce DSO Lump and Fines products, with an estimated average Lump product grade of ~62% Fe and Fines product grade of ~59% Fe.
Mining, crushing and screening and haulage operations will be undertaken by specialist contractors with overall supervision and management provided by Strike’s ‘Owner’s Team’.
The detrital ore requires no drill and blast activities and will be undertaken predominantly through very shallow trenching and screening operations. The detritals area sits partially over the area of the open Main Pit and as such, the mining of the surface material will assist in the development of the Main Pit during Stage 1.
Iron ore mineralisation outcrops on top of the ridge, which protrudes between ~40 to 60m above its base.
It is envisaged that a ‘pioneering mining fleet’, comprising a small 50 tonne excavator and associated articulated dump trucks (ATD’s), together with two drill and blast drill rigs, will be required initially in order to access the top of the ridge, as well as to establish and mine the initial benches.
Once the pioneering fleet has established three to four mining benches across the upper portion of the ridge surface, the production mining fleet will commence mining. The production fleet will utilise a 105 tonne excavator, with waste and ore transported to waste dumps and the ROM pad respective ........
