More high grade graphite for BlackEarth in Madagascar

The initial trenching results from Ianapera represent some of the highest graphite grades being achieved globally at present. The company undertook the maiden trenching program at Ianapera late last year and covered about 4.5km of strike on highly conductive zones that were inferred to host graphite mineralisation from an interpretation of the available geophysical survey imagery.

The hole was sited about 40 m east of Site #2 where holes BK1-03-17 and BK1-04-17 drilled to the north intersected significant graphite intervals as previously reported with analyses. BK1-14-17 was drilled to the east with a -60 inclination and reached 109.7 m length.

Flinders' Woxna Graphite Project Delivers Positive

Graphite concentrate is dewatered in a new filter press then dried in the existing drier. Screening and packing of graphite product largely utilises existing equipment. A new flake product exceeding 250 micron and 94% purity is produced in addition to the graphite grades produced historically.

PRELIMINARY MINERAL PROCESSING R.K ON THE GRAPHITE

For these reasons, graphite analyses were performed using the Leco procedure for low level determinations and the D.L.O.I. procedure for high level determinations. Head grades for the composite samples were determined from metallurgical balances. The 17.5%

Volt Resources

Volt's recent pre-feasibility study on Namangale outlines a 170ktpa operation feeding a high-purity graphite concentrate into the lithium-ion battery (LiB) and expandable graphite end-markets. We have compared Namangale to six of the most advanced East African graphite projects and note Volt's high ranking in terms of estimated operating margin and concentrate purity.

BlackEarth Minerals (ASX:BEM) welcomes encouraging test

2021/3/31BlackEarth Minerals' Managing Director, Tom Revy, commented that the board is delighted with initial test results achieved at the BGRIMM graphite processing and design facility. Undertaking this large scale pilot test program is a significant commitment by BlackEarth and we were confident the program would achieve very positive results, he said.

High grade surface graphite for BlackEarth in Africa

According to BlackEarth, the initial trenching results from Ianapera represent some of the highest graphite grades achieved globally and certainly within Madagascar. The higher-grade mineralisation at the project appears to be concentrated in four specific zones of higher electrical conductivity and all were targeted during the recent surface trench sampling program.

Department for Energy and Mining

Total graphite resources across all Eyre Peninsula deposits, as at June 2017, exceeds 100 Mt with grades ranging from 3 to 17% TGC, for ~8.6 Mt of in situ graphite (Table 3). The resources and grades are significant in terms of current world demand for natural

(TSXV: SRG) ("SRG" or the "Company") is pleased to announce that it is now producing 95% graphite samples from its metallurgical laboratory at the Lola Graphite Deposit in Guinea, West Africa.

Focus Graphite Reports High Grade Drilling Results from

Total carbon assays are for the higher graphite concentrate grades, whereas graphitic carbon assays are for drill core and it is a more accurate method when graphitic carbon content is lower than approximately 50% Cg. 2014 Exploration Drilling Program

Comet Resources: Excellent Graphite Grades Achieved

The graphite concentrate produced has a unique and potentially very valuable characteristic in its size distribution, with 2/3 of the product passing the 38 m screen. Generally, this size fraction of graphite is mainly a by-product of processing of larger flake fractions, which produces smaller size graphite, but this damages the flakes in the process, reducing their performance and value.
