Summary:

Mine area rocks are composed of a mafic to felsic volcanic-sedimentary sequence. The volcanic sequence consists of a Lower Andesite overlain by the Lower Agglomerate unit, a Lower Tuff, the Upper Agglomerate, and Upper Tuff units. A rhyolite porphyry stock occurs to the north of the mine and is exposed in the SAMS area. This stock may be part of a much larger intrusive body at depth.

The rock sequence forms an east trending homoclinal structure trending east with a northerly dip from 30° to 75°. At depth the sequence is sub-vertical to overturned. These rocks have been complexly faulted by steeply dipping north to north-northwest and northwest trending faults. Vein complexes trend north-northwest to north with some veins trending northwest.

Mineralisation is associated with multiphase quartz veining and silicification developed along predominant north to north-northwest trending faults. Some veins are developed along northeast and northwest trends. Quartz veining is associated with intense silicification, massive, laminated and brecciated veins. Veins are vertical to sub-vertical. Major vein systems can be traced across the mine area and are preferentially developed in the Lower and Upper Agglomerate Units. Veins are more poorly developed in the andesite and tuff units. Economic gold mineralisation is associated with quartz, pyrite, chalcopyrite, sphalerite, galena and silver.

Moderate to intense sericite and chlorite alteration is associated ........


Mining Methods

  • Mechanized Cut & Fill
  • Sub-level stoping


Summary:

The underground mine has over 60km of tunnels, and is mined over a vertical depth of 300 metres from the surface.

The main access to the underground operations is provided by a 1:9 decline, 4m by 4m in cross section which runs from the portal at 1,065m amsl to the 852m level. Access from this decline to the orebodies is via ramps and cross-cut haulages.

Mining methods include fully mechanised sub-level stoping and cut-and-fill with application depending on orebody dimensions. Each cut is either 2m or 4m depending on orebody geometry and fill is placed in the stopes after each cut and stopped with sand (>50cm), which also acts as a marker between ore and waste.

All primary waste development, ore development and the cut-and-fill stopes are drilled using electro- hydraulic drill rigs.

Mining operations extend to a depth of 190m from the general desert surface. Ground conditions are generally good although (ground conditions) in localised areas is poor which necessitates the use of roof-bolts, sometimes in combination with mesh. No formal support system is left in the stopes, however low grade areas are left in-situ which also limit mining spans.

Mining activities are serviced with compressed air from a central facility with an installed capacity of 231m3/min provided by five compressors, three of which are operational at any one time. Ventilation is provided via the main decline and all air is exhausted via a separate incl ........
