Deposit Type

  • Metamorphic


Summary:

The Balama Central comprises two prospects named Lennox and Byron which are composed of relatively simple geology with interpreted steeply dipping northwest host lithologies. The graphite forms as a result of high grade (amphibolite) metamorphism of organic carbonaceous matter.


Mining Methods

  • Truck & Shovel / Loader


Summary:

Mining at Balama Central will be completed with standard truck and excavator methods. Drill and blast of the fresh material will be required. Pit designs for Lennox and Byron were based on Whittle pit optimisations for each deposit considering project specific unit costs, prices, recoveries and geotechnical inputs. The pit optimisations were constrained within the limits of the Indicated Resources for each deposit. The current design for the Lennox pit extends to a depth of approximately 90m, whilst the current design for Byron pit extends to a depth of approximately 135m deep. Each pit will have a single waste dump, located to the east of each excavation. Pit ramps will be oriented to ensure that both ore and waste haulage distances are minimized. Long-term ore stockpiles will be located between each pit and the ROM pad.

A mining schedule was completed based on the processing plant target production of ~58 ktpa of TGC concentrate at 96% TGC and practical mining constraints. A 75% ramp-up was applied in the first year. To enhance early cashflow, the target feed grade to the plant will average 12.5% TGC. This is maintained for 29 years before reducing.

The cut-off grade was determined through the application of project unit operating costs and recoveries. The recoveries were determined by deposit scale geometallurgical assessment of samples representative of the variable lithology types, oxidation and TGC% grade ranges. The marginal cut off estimated to ........
