Battery electrodes were compared with commercially available synthetic graphite powders, which were then used to construct coin cells in a half-cell configuration. The performance of Campoona graphite in terms of charge capacity, was at least equivalent to that of the commercially available synthetic graphite. (NB Over 30% of Li-ion batteries use synthetic graphite).

Sugarloaf carbon research and DEVELOPMENT
==> picture [249 x 67] intentionally omitted <==
Huge resource potential
-
Sugarloaf hosts unique carbon deposit with an exploration target of 40 – 70Mt at 10-12% TC*
-
Carbon within meta-pelite
-
Geochemistry suggests iron sulphide deposit affinities with elevated copper and zinc, proximal manganese, silver and gold
-
Copper “blows” on western flank of Sugarloaf Hill
-
EM shows large conductive body at depth
-
ELA 2015/215 approved which covers up to 4km extension to Sugarloaf
-
It must be noted that whilst the Exploration Target is large, the potential quantities and grades presented in the Exploration Target are conceptual in nature, there has been insufficient exploration to define an overall Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource .

2. Sugarloaf carbon research and DEVELOPMENT
==> picture [311 x 257] intentionally omitted <==
Unique carbon material
-
Initial research conducted in collaboration with the University of Adelaide directed at creating graphene from Sugarloaf carbon was successful from both ores and concentrates
-
Next was to try to use graphene to slow the solution rates of commercial fertiliser
Crystalline Campoona graphite
-
Graphene extracted from Sugarloaf carbon was successfully applied as a coating to superphosphate which appreciably slowed the release rate of nutrients
-
However, the cost of making graphene combined with the cost of applying a coating of graphene on an already expensive fertilizer, was likely to be cost prohibitive for farmers
==> picture [291 x 218] intentionally omitted <==
-
Research then looked at Sugarloaf carbon itself given its unique physical and chemical characteristics that distinguish it from crystalline graphite
-
Sugarloaf consists of porous, matted, predominantly nongraphitic carbon with low crystallinity
Porous carbon accretions from Sugarloaf
-
Sugarloaf carbon has elevated concentrations of macro- and micro-nutrients that occur in both highly soluble and low solubility forms providing immediate release and longer-term release of nutrients to plants
-
The nutrient levels are however too low for Sugarloaf carbon to be used as a fertilizer on its own
15
Sugarloaf carbon has potential application as soil ameliorator
Sugarloaf carbon
==> picture [249 x 67] intentionally omitted <==
Improves soil wettability and moisture retention
-
Initial results from Adelaide University indicate:
-
carbon additions improve soil wettability and the soil’s ability to retain moisture
-
presence of trace elements found in fertilisers
-
assists plant growth
-
This carbon could be produced at very low cost
-
40m thick outcropping horizon
-
No beneficiation
-
Simple mining, crushing and bulk loading
-
Next phase of testing will include plant trials over entire growing “season” comparing dosage rates of Sugarloaf carbon and superphosphate
