In general, ore at Miitel is located at the steeply dipping contact between footwall basalt and a less competent hanging wall ultramafic unit.

The majority of the Miitel area consists of the N30 and N31 lodes. Both areas strike roughly north-south. The N31 has a strike length of ~180m, extending from ~-400m RL (~705mbs) to -300m RL (100m extent). The N30 has a strike length of ~450m, extending from ~-580m RL (~885mbs) to -430m RL (150m extent) and plunging gently to the south. Both areas consist of single lodes dipping sub-vertically (60-70°) to the east, with widths from 1-8m (N31) and 2-10m (N30).

There are two mining areas in the Burnett mine plan, being the B01 and B02 areas. Both areas strike at ~330-340°. The B01 has a strike length of ~260m, extending from ~-415m RL (~725mbs) to -290m RL (125m extent). The B02 has a strike length of ~340m, extending from ~-460m RL (~420mbs) to -310m RL (150m extent). Both areas consist of single lodes dipping sub-vertically (>80°) to the north-east, with widths ranging from 1-5m.

The orebodies are planned to be accessed through the existing Miitel portal and decline. The Miitel decline will require dewatering and rehabilitation of ground support and services prior to the commencement of development.

Currently the mining schedule allows for the mining fleet (including personnel) at Miitel to be sourced from the Northern Operations. This will be dependent on whether mine life can be extended at the Northern Operations.

Based on the orebody spatial and geotechnical characteristics, the primary mining method proposed is bottom-up longitudinal longhole stoping (LHS) with modified Avoca assuming cemented rockfill (CRF). Vertical sub-level intervals are 15-20m floor-to-floor. Areas without top access (i.e. crown stopes or levels directly beneath sill pillars) will be mined using conventional longhole open stoping, retaining in-situ pillars for support. Maximum open stope strike lengths of 12m have been applied based on geotechnical advice. Slots to open stoping spans have been designed assuming handheld development methods. Subsequently mined stopes in filled levels will be fired against fresh CRF without the requirement for additional slotting. Some areas will be mined using overhand cut-and-fill methods or airleg stoping, dependent on orebody geometry.

Drilling and blasting will be carried out using conventional electric over hydraulic drill rigs and diesel charge wagons. A modern diesel mechanised fleet will load and ha ........
