Figure 5. Sample of graphite concentrate from Ancuabe at 98% TGC.
By world standards, Triton’s Ancuabe material compares favorably when benchmarked against various other graphite deposits. Figure 6, shows a graphical representation of the main flake size categories and the characteristic flake distribution for each deposit within these categories.
Most significantly, is the dominant proportion of recovered large flakes sizes at the Ancuabe project, with over 92% at >100 mesh (150μm).
Triton considers that these metallurgical results confirm that Ancuabe has the potential to become a market leading graphite project. Analysis of publicly released information from peer graphite companies shows that the Ancuabe graphite has the best flake size distribution in the world and the largest majority of jumbo and super jumbo graphite flakes, with 92.1% of the graphite flakes are than larger than 150μm (+80 mesh) and 84.4% larger than 212μm.

Note: Excepting Triton, there may be a minor error in some categories shown above due to the various styles of reporting with respect to flake size ranges and thus this graph should only be used for approximate comparative purposes.
These outstanding results were obtained through a minimal series of crushing, grinding, rougher and cleaner flotation, without the need to complete a regrind of the graphite concentrate. The reduced processing requirements during the graphite flotation will likely have a positive impact for Triton reducing the time and energy needed to complete the process. A yield, or mass pull, of only 15.4% essentially means that less material needs to be processed to produce a specific amount of concentrate.
Ongoing optimisation of the metallurgical process is expected to further enhance the quality of the final product concentrate. The Company is conducting further tests to explore options to reduce energy requirements in the milling circuit, which could further reduce future operating costs.
CONCLUSIONS
The latest metallurgical results from Ancuabe confirms the very high quality nature of the Ancuabe graphite project and signify positive implications for potential downstream economics.
Should the upcoming drilling program help Triton to demonstrate economic quantities of large and jumbo flake graphite at Ancuabe, it could complement the TMG products range and provide the Company with the potential to produce large volumes of high grade (high value) graphite in the full range of flake sizes, thereby accommodating a wider range of end-user requirements.
