Lincoln Minerals’ confidence is up on its graphite resource at the Kookaburra Gully Graphite Project following recent drilling results from the project area.
Results from aircore drilling done in January and March this year revealed several high grad graphite intervals of up to 24.7 15.2 per cent total graphitic carbon (TGC).
This follows results from diamond core and air core drilling done last year which showed a combined measured, indicated and inferred mineral resource of 2.03 million tonnes of graphite at 15.2 per cent total graphitic carbon (TGC).
Metallurgical tests show graphite concentrates can be produced at up to 98 per cent TGC.
Lincoln Minerals managing director John Parker said the tests were done on bulk samples collected from a number of drill holes.
“The master sample used was 150 kilograms collected from various drill holes,” he said.
Dr Parker said there was a lot of confidence in the quality of the graphite resource itself and in the concentrates that could be produced.
He said these latest results had put Kookaburra Gully amongst the top 10 deposits in the world on the basis of grade.
“The fact we have got a high grade deposit helps us to keep operating costs down,” he said.
Lincoln Minerals has done further drilling at the site this year with results expected to be released in the next week.
Dr Parker said Lincoln Minerals was aiming to submit its program for environment protection and rehabilitation by the middle of the year, which once approved by the state government would mean all approvals were in place.
“I would like to think that by the end of the year we would have all approvals done and mine development can begin,” he said.
Lincoln Minerals has collected a 36.9 tonne sample of oxidised graphite from Kookaburra Gully which will be used in pilot plant test work and generation of flake graphite concentrates for product evaluation.
