Mustang Resources Ltd (ASX:MUS) has conducted further metallurgical test work on oxide and fresh samples taken from its 80% owned Caula Project, providing more firm evidence of the quality of the mineralisation.
The Caula Project is located along strike from Syrah Resources’ (ASX:SYR) world-class Balama Graphite Project in Mozambique.
Mustang Resources revealed a maiden JORC resource estimate for its 80% owned Caula graphite deposit in November.

Test work produces improved flake distribution
The test work produced an improved flake distribution on the oxide material.
It also quantified the proportion of high revenue super jumbo (>500 µm) flake and improved the amorphous (<75 µm) grade from both oxide and fresh samples.
Ian Daymond, interim executive chairman, said: “Every round of work at Caula provides more evidence of the project’s potential to become a low-cost graphite supplier to the fast-growing lithium battery and expandable graphite industries.”
These results are based on additional test work aimed at providing further information to enhance the upcoming scoping study.
Samples compiled from 2016 resource drilling campaign
Samples were compiled from quarter diamond drill core samples collected during the 2016 resource drilling campaign at Mustang’s Caula graphite deposit.
Optimum recoveries were achieved from the initial test work with oxide samples returning total graphitic carbon (TGC) of 87% and recording 96%.
Mustang Resources expects TGC recoveries to improve during future test work phases through further flowsheet optimisation and recycling of intermediate tailings streams.
Open circuit testing delivers improvements in flake distribution and grades
Improvements in both flake distribution and concentrate TGC grades were achieved from the second round of tests on the oxide ore.
The proportion of potential high revenue super jumbo flakes (+500 µm) was quantified and a premium saleable amorphous product (96%) produced on the fresh sample.
Daymond also said: “These results are outstanding and will help underpin the impending scoping study."
