Deposit Type

  • Vein / narrow vein
  • Pegmatite


Summary:

The currently explored deposit has an extension in strike of 1500 m. The maximum vertical extension is about 400 m (1600 masl to 1320 masl), but varies along strike due to varying exploration strategies in the past. The veins are steep to medium dipping and most of them have expressions on the surface. It is expected that the deposit continues deeper than currently explored.

The resource comprises multiple parallel lithium-bearing pegmatite veins dipping at around 60° hosted in eclogitic amphibolite and mica schists.

The width of the veins averages 1.35 m with maximum width recorded at 5.5 m. Intersection lengths in the boreholes were logged but not sampled if less than 0.5 m.

Underground development and drilling shows that there is good continuity of the veins along strike. 15 veins have been included in the mine design. The pegmatites are predominantly quartz-feldspar-spodumene with only minor impurities. Spodumenesize varies from a few mm up to 15mm in the coarser pegmatite hosted by the amphibolite rock unit.


Mining Methods

  • Longhole open stoping
  • Cemented backfill


Summary:

SRK has determined that long hole open stoping is the preferred mining method and, following geological mapping underground and rock characterisation, a standard stope of 25m high by 75m wide with 4m rib and sill pillars is deemed appropriate for design. A crown pillar of 25m was considered adequate.

A minimum mining width of 1.2m has been considered practical and a dilution skin of 0.5m in the hanging wall and 0.3m in the footwall has been applied. This results in average dilution of 40% and a ROM grade of 0.71% Li2O. Ore sorters will be used to reject waste such that the grade to the concentrator is increased to 1.03% Li2O.

Mine access will be by the existing adit, increased in size to 5m x 5m, and a main decline developed in the competent amphibolite. Mining will be carried out using 25m sub levels and cross cuts will be developed from the decline every 25m and all veins intersected.

Remote loaders will be used to load from the stopes to a local stockpile where 30 tonne trucks will be loaded for transfer of RoM to the underground crusher and ore sorter. A second decline will be developed from the underground crusher/sorter to the surface plant for product haulage. Mica schist waste from the sorters will be returned to mined out stopes whilst amphibolite waste from the sorters will be trucked to surface and used for construction material. This allows the project to proceed without permanent surfac ........


Crushing and Grinding
Flow Sheet: Source

RoM is crushed in two stages underground and screened. The +8mm goes to ore sorting using lasers in two stages where the waste is rejected. The accepted material is combined with the -8mm material and undergoes two further stages of crushing and is then trucked to surface.
