Summary:

The Bellevue Project is located within the Agnew-Wiluna portion of the Norseman-Wiluna Greenstone belt, approximately 40 km NNW of Leinster. The project area comprises felsic to intermediate volcanic sequences, meta-sediments, ultramafic komatiite flows, Jones Creek Conglomerates and tholeiitic meta basalts (Mt Goode Basalt) which hosts the known gold deposits.

The major gold deposits in the area lie on or adjacent to north-northwest trending fault zones.

The Bellevue gold deposit is hosted by the partly tholeiitic meta-basalts of the Mount Goode Basalts in an area of faulting, shearing and dilation to form a shear hosted lode style quartz/basalt breccia.

Gold mineralisation in the area is structurally controlled and is generally associated with north-northwest striking and west dipping shear zones (dipping from 900 to 450), of 1 to 20 metre thickness. The exceptions are the Viago Lode, which is a low angle shear zone between 300 and 500 metres below surface which gently plunges to the south, and the Westralia and Vanguard lodes, which dip 450 to the north-east.


Mining Methods

  • Truck & Shovel / Loader
  • Cut & Fill
  • Longhole open stoping
  • Avoca
  • Cemented backfill


Summary:

The majority of the Ore Reserves (>98% of Ore Reserve metal) are planned to be mined using conventional underground methods. The remainder of the Ore Reserves are planned to be extracted using conventional open pit mining methods on the near-surface portions of the Tribune and Vanguard lodes. A third open pit system, Hamilton/Henderson/Bellevue, is included in the LOM project plan.

The open pits are planned to be mined using a conventional diesel fleet of 120 t excavators and 90 t trucks. A smallest mining unit (SMU) modification process was carried out on the relevant Mineral Resources to ensure realistic modifying factors were applied to the forecast ore production. A minimum SMU of 3 m (2 m minimum mining width with 0.5 m dilution on each HW and FW contact) was applied, having regard for the fleet type and orebody spatial characteristics.

The Feasibility Study contemplates mainly underground mining and four small open pits. Detailed underground mine designs were then carried out on the deposit incorporating the optimisation results, and these were used as the basis of the Ore Reserve estimate. Modifying factors were applied to the design and a mine plan was subsequently scheduled. All Ore Reserve material is planned to be mined using underground methods. The underground mining methods used to estimate the Ore Reserve were applied based on the spatial characteristics of the lodes.
