Campoona exploration history
-
Airborne EM surveys conducted as part of base metal exploration in the mid-1980s indentified several highly conductive bodies along the Campoona graphite trend. An historic shaft (circa 1915) exists on the graphite.
-
Other elongate EM conductors, parallel to Campoona were drilled by ESSO at High Bluff and were confirmed as graphitic in origin.
-
A 1991 petrology report identified the graphite ranging in size 0.1mm to 0.3mm with an average flake size of 0.2mm or 200 microns.
-
Two samples were collected in June 2011 and submitted for petrological examination by Pontifex and Associates in Adelaide. Results confirmed the 1991 observations. Graphite content was reported as 25-30%. Size ranged mostly 10-50 microns (width) x 250 microns (length).

Campoona geophysics
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 with attendant amphibolite intrusives 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 parallel possibly fold repeated conductors to the southeast which are yet to be drill tested.
==> picture [720 x 22] intentionally omitted <==
11
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). All feldspar has been converted to kaolin. Discrete thin clay-rich zones occur probably as cavity fill rather than as 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 intrusions, has segmented the graphite pods.

-
Hangingwall contact between soft highly weathered gneiss and 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 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
==> picture [720 x 22] intentionally omitted <==

Campoona metallurgy
Lonsdale Sample Facility
-
Established during September 2012.
-
Facility provides a metallurgical workshop and a bulk sample storage area for the preparation of bulk samples to be sent to commercial laboratories for metallurgical trials.
-
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.
Interim DDH Metallurgy Results Samples to BOCO
-
Base of complete oxidation (BOCO) at 5060m depth.
-
Rock is largely decomposed resulting in easier mining and comminution.
-
In clay-rich horizon approximately 40% of available graphite produced by simple washing of clays.
-
Metallurgical trials for extraction and concentration indicate grades can meet market requirements.
-
Optimum process flow sheet nearing completion.
Samples below BOCO
==> picture [268 x 151] intentionally omitted <==
-
Strong oxidation persists to ≈100m.
-
Tests outstanding.
A combination of traditional and widely adopted new technologies will be used to process all three material types: clay-rich upper horizon; above BOCO and below BOCO
==> picture [720 x 22] intentionally omitted <==
14
Campoona strategy
-
Define optimum process flow sheet.
-
Establish minimum aggregate JORC Resource* of 5Mt at Campoona Shaft and Central Campoona.
-
Bulk sampling and pilot scale testing to produce samples for marketing.
-
Establish markets for Campoona graphite.
-
Drill test northern and southern extensions at Campoona .
-
Drill test regional graphite targets to rank potential.
*It is not possible to confirm at this time whether Mineral Resources or Ore Reserves will be defined in accordance with the JORC Code at the Campoona Graphite Deposit
