Campoona EM
Airborne EM has highlighted probable strike extensions to Campoona Shaft and Central Campoona
-
EM provides an effective tool to identify the presence of conductive bodies.
-
EM has identified several possible graphite bodies along strike from the known graphite occurrences at Campoona Shaft and Central Campoona.
-
Late stage cross faulting has “segmented” the graphite to form discrete bodies.
-
Campoona Shaft and Central Campoona account for just 2km of strike of highly graphitic schist. ( see black bars)
-
A further 8km of likely graphite is yet to be drill tested. (see blue bars)
-
EM suggests the possibility of a parallel (fold repeated?) signature to the southeast which requires drill testing.
==> picture [720 x 21] intentionally omitted <==

Campoona Shaft geology
-
Graphite deposit outcrops and forms a discrete NE striking, steep NW dipping, 20-50m thick main zone with two narrower and discontinuous footwall zones.
-
Campoona graphite occurs as highly graphitic schist within a low grade graphitic proto-gneisses.
-
The proto-gneiss is derived from mostly clastic marine sediments of Palaeoproterozoic age.
-
Methane possibly from submarine volcanism was encapsulated into the marine sediments. Upper amphibolites facies metamorphism has converted the carbon to crystalline graphite.
-
Below the soil is a thin (≈5m) clay-rich highly graphitic zone which passes into highly weathered, porous quartz + graphite + kaolin + garnet + tourmaline ± iron oxides (goethite & hematite). Any remaining feldspar has been converted to kaolin. Discrete thin clay-rich zones occur more as cavity fill than defined horizons.
-
Below 60m depth the graphitic schist becomes more competent. Strong weathering persists to at least 100m depth. Feldspars have been converted to illite ± kaolin. Sulphides in the form of pyrite occur irregularly in trace quantities.
-
Late stage NW trending cross faulting, often with attendant amphibolites intrusives, has segmented the graphite pods.

-
Hangingwall contact with soft highly weathered gneiss passing directly into completely oxidised graphitic schist.
-
Note absence of graphitic clay layer.
-
Graphite interval 11-13m assayed ≈12%TGC.
-
Highly weathered, porous quartz + graphite + kaolin + garnet + tourmaline ± iron oxides (goethite & hematite) representing the graphite deposit above the base of complete oxidation (BOCO).
-
Interval from 54-58m assayed 19.5%TGC
-
Strongly weathered graphitic schist below BOCO.
-
Feldspars altered to illite ± kaolin.
-
Graphitic schist is more competent but still strongly oxidised.
-
Interval 80-83m assayed 18.9%TGC
Complete oxidation is a defining characteristic of the Campoona graphite deposits as it greatly enhances the liberation of graphite from gangue minerals

Campoona metallurgy
Lonsdale Sample Facility
-
Established during September 2012.
-
Facility provides a metallurgical workshop and a bulk sample storage area set up for weighing, washing, wet-screening, drying, crushing, splitting and blending of specially prepared bulk samples to be sent to commercial laboratories for flotation tests.
-
Further in-house testing capability is being developed to allow for the bench scale testing of differing extractive processes.
-
Ore microscopy established to provide visual assessments of performance of intermediate processing steps.
==> picture [269 x 151] intentionally omitted <==
Interim DDH Metallurgy Results Samples within BOCO
-
BOCO at 50-60m depth.
-
Rock largely decomposed resulting in naturally liberated graphite.
-
Approximately 40% of available graphite produced by washing of clays.
-
Metallurgical trials indicate grades can meet market requirements.
-
Testing will continue to develop optimum process flow sheet.

Archer Magnesite – Leigh Creek magnesite
-
Magnesite (MgCO3) was deposited as a chemical precipitate in shallow, marginal marine lagoons and occurs as cryptocrystalline particles 1–5 µm in size. 86 separate interbeds within the Skillogalee Dolomite.
-
Magnesia (MgO) is produced by heating magnesite typically to1000[o] C. Main magnesia products are:
1. Caustic Calcined Magnesia (CCM) is formed by heating magnesite to temperatures up to 1,000[o] C. It is reactive and that reactivity is important for construction materials, industrial applications, in fertilizers and as a soil conditioning agent in agriculture, for water purification and waste water treatment and in the paper and rubber industries.
2. Deadburn Magnesia (DBM) is produced by heating CCM to temperatures of 2,300[o] C to produce inert magnesia capable of withstanding temperatures up to 3,600[o] C. Deadburned magnesia is used in the production of refractory bricks.

1 Pure magnesite is 47.8% MgO
Magnesia products widely used across a number of high growth industries and high technology consumer goods. MgO Market grows at ≈330ktpa. Market - 63% refractories; 23% chemicals; 14% magnesium metal

Archer magnesite summary
Key Attributes
-
High grade magnesite deposits.
-
Enormous value proposition:
-
It takes 3t of magnesite to make 1t of magnesia. Value of magnesia between $400 - $600/t.
-
Huge JORC Resource could support very long-term operation.
-
Fully serviced town of Leigh Creek nearby.
