Initial exploration in Tanzania serves up jumbo flake for Prospect
Prospect Resources (ASX:PSC) reports that initial petrographic work at its Chiliogali Graphite Project in Tanzania confirms the presence of ‘in-situ’ coarse graphite flake sized up to 1mm (1000 microns). PSC also published upbeat exploration results earlier this month after acquiring an option on the Chiliogali Project last November.
The discovery is significant because graphite flake size is directly related to final graphite sale prices at market.
In an announcement to the market earlier today, PSC says there is no indication of any issues in liberating the graphite with little evidence of mineral inclusions within the graphite. “There are zones of large graphite flakes that are associated with, but not intergrown with quartz, which should therefore be easy to liberate,” said PSC.
Both these aspects could boost PSC’s exploration success and subsequent Resource definition.
PSC hopes that its Project location and neighboring infrastructure, namely the port of Mtwara, will act as catalysts for strong project economics as exploration continues and moves into the later stages. The Chiliogali Project is around 180km west of Mtwara Port in Southereastern Tanzania, easily accessible from the well maintained Masao-Lindi-Mtwara road.
However, PSC did confirm the presence of biotite, an accessory mineral, which makes up less than 5% of the extracted material. “The small amounts of biotite that are present are not intergrown with the coarse graphite, and will not likely [sic] cause problems with flotation.”
All of PSC’s most recent samples have now been sent for metallurgical testing that will likely clarify exactly how PSC’s graphite stacks up in comparison to its regional neighbours in Tanzania. PSC claims that despite only “limited metallurgical test work” being done, it “seems that concentrates of >98% carbon are possible”.
Should PSC be able to prove up high carbon test results as part of its exploration, the micro-capped explorer would place itself in amongst some illustrious peers in the region that are more advanced in their exploration.
The likes of Mozambi Resources, Magnis Resources and Kibaran Resources are all junior explorers currently pursuing graphite exploration in East Africa, close to the richest graphite region in the world – Cabo Delgado in Mozambique.
Geologists strongly believe that veins of graphite schist mineralisation stretch out across East Africa with Tanzania currently a prime location for graphite exploration.
