Graphite Market

Photomicrograph - Growth spirals in graphite crystal

Amorphous Graphite

Microcrystalline graphite ≈70% of world production and consumption. Graphite content ranges from 15% to 99% C. Widely used in industrial applications for its high melting point, resistance to thermal shock and lubrication .

Crystalline Flake Graphite

Flake graphite occurs only in a few locations around the world usually as flat platy crystals disseminated in metamorphic rocks. Total carbon grades are generally low ranging mostly from 2-6% C and rarely >10% C.

Flake graphite is classified and marketed based on the size of the graphite crystals (flake size) and by the carbon content (generally >94%C). Strong growth from high tech uses. Three main flake sizes:

Fine flake (-100 mesh or <149µm)

Medium flake (+100 -80 mesh or 149–177µm) Large flake (+80 mesh or >177µm)

Substitution of graphite by other minerals is highly unlikely as there is simply no other mineral so versatile and with such unique physical and chemical properties.

China produces around 75% of the world’s graphite. Quality is declining and supply suffers from the seasonal closure of mines in northern China over winter. Several SOE operations have been closed to preserve resources. China has imposed a 20% export duty plus a 17% VAT and has instituted an export licensing system to ensure supply to its domestic economy.

The dominance of China as a producer coupled with measures introduced by the Chinese government are creating supply concerns for the rest of the world. Supply issues are exacerbated by the lack of exploration and new mine development.

Graphite Demand Trends

  • Traditional Uses : Steelmaking, refractories, auto parts, gaskets, composites, batteries, semiconductors, carbon

  • brushes and oils and greases is increasing with increasing industrial output.

  • Emerging Uses : Growth in the flake market from increased demand from high value strategic applications in

  • electronics and computers and high tech uses constantly being identified.

1. Lithium-ion battery market : Having a significant impact on the graphite market especially for the prized flake graphite as the demand for mobile energy storage systems increases. Lithium-ion batteries for EV and HEVs - USA has 200,000,000 of the estimated 750,000,000 cars in the world. UCLA research predicts that by 2030, 64% of all US made cars will be electric. US government has provided billions of dollars in loans, grants, and tax incentives for research in support of US auto industry and battery manufacture.

  • ( Each HEV requires ≈ 11kgs spherical graphite. Up to 70% of flake is destroyed making spherical graphite)

Graphite Demand Trends

Growth in the flake market also coming from green energy initiatives including fuel cells and new generation nuclear power and from the evolving applications for graphene.

2. Green energy initiatives : especially fuel cells and solar electricity applications. Governments worldwide are backing green energy initiatives in response to the threat of climate change. Fuel cell technology is seen as the future for sustainable, portable, self- contained energy solutions.

3. Pebble bed nuclear reactors (PBNR) : offer a solution for safe nuclear power. In PBNRs the fuel is embedded in graphite balls . PBNRs are cheaper to build and operate than conventional reactors, use inert gases as coolants rather than complex water cooling systems and cool naturally when shut down. They operate at higher temperatures giving more fuel efficiency and they can directly heat fluids for low pressure gas turbines.

4. Graphene : is set to have a profound impact on the future development of mankind. Potential applications include replacement of silicon in semi-conductors; replacing of carbon fibers in composite materials to enable lighter and stronger aircraft; an additive or coating to plastics to enable them to conduct electricity; increasing the efficiency of electric batteries; transparent conductive coatings for solar cells etc. The list is expanding all the time.

Graphite Market Trends

==> picture [18 x 18] intentionally omitted <==

Graphite is facing increasing demand worldwide from growing traditional uses and rapidly emerging new technological applications.

==> picture [50 x 53] intentionally omitted <==

Archer likens the emerging importance of graphite to that of the recent history of Rare Earth Elements (“REE”) and lithium. Few people realized how quickly REE and lithium would increase in importance as more and more advanced applications were discovered. Fewer understood the strategic importance of REEs and lithium. The Company with its extensive landholding hosting a large number of “high grade” outcropping graphite occurrences (including rare and prized large flake graphite) is in a strong position to rapidly advance exploration and capitalize on the surging demand .

Sugarloaf Graphite

  • Sugarloaf area first explored for gold, base metals and uranium.

  • Goldstream then Helix identified a coincident gold and copper soil anomaly. The two companies drilled a total of 41 drill holes across Sugarloaf. Best intercept was 3m @ 1g/t Au in a laminated quartz vein.

  • 23 of the 41 drill holes recorded wide intervals of graphite however no assaying for carbon was undertaken. Historic samples were not retained.

  • In 2008 Archer drilled 5 RC holes to further test the gold and copper potential. The northernmost drill line including CHRC010 was assayed for carbon.

  • In 2010 Archer negotiated a farm-in agreement on the neighbouring Wildhorse Plain primarily to explore for manganese, copper and iron ore. A review of the exploration literature on Wildhorse Plain identified widespread graphite occurrences. This review highlighted the potential of the area for graphite.

  • In 2011 Archer drilled 4 holes essentially twinning historic drill holes to assess the accuracy of reported graphite intervals. This results of this work was the start of Archer’s foray into graphite.

Whilst at an early stage of evaluation, Sugarloaf has excellent potential

==> picture [720 x 80] intentionally omitted <==

Sugarloaf Graphite

Summary

  • 100% owned Sugarloaf deposit has Exploration Potential of 24 – 37Mt grading 10-12% total

  • carbon*. The estimate is for the western graphite limb only.

*The potential quantities and grades presented 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

  • Petrology indicates deposit consists of fine graphite with average size of 100µm which is likely to provide largely amorphous product.

  • Deposit outcrops, is sub-vertically dipping and has a consistent aggregate true width of 40 metres.

  • Open along strike to the north and at depth.

  • Trenching and aircore / diamond drilling planned for January – March 2012 to provide appropriate samples for graphite characterisation tests.

Sugarloaf Exploration Potential very likely to increase

==> picture [720 x 80] intentionally omitted <==

Wildhorse Plain Graphite

Significant regional potential – Campoona

In the mid 1980s airborne electro-magnetic surveys were conducted as part of exploration focused on base metals. A highly conductive graphitic schist over 6km long was identified adjacent to the Lower Middleback Jaspilite at Campoona Hill . A historic shaft (circa 1915) exists on the graphitic schist.

Other elongate EM conductors, which are parallel to the graphitic schist 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.

Two samples were collected in June 2011 and submitted for petrological examination by Pontifex and Associates in Adelaide. Results confirm the 1991 observations. Graphite content was reported as 25-30%. Size ranged mostly 10 µm-50 µm (width) x 250 µm (length).

Wildhorse Plain Graphite

Significant potential – Campoona South

At the southern end of the Campoona EM anomalies lies a graphite outcrop that assayed 25.4% C .

Hand specimens had visible large flake graphite to 1,000µm (1mm).

Petrological examination reported graphite content at 15-20%. Overall graphite size ranged from 5µm to 80µm (width) x 300µm (length) with an average size estimated at 50µm x 250µm (large flake).

Graphite occurs within “heterogeneous, fine layered quartz-feldspar microgneiss, together with quartz-graphite schist”.

Flake graphite identified in several locations on Wildhorse Plain associated with high grade metamorphic rocks

==> picture [720 x 80] intentionally omitted <==

Wildhorse Plain Graphite

Significant potential – Council Pit

The Council Pit is a disused historic borrow pit.

The graphite content was reported between 15-20%. The overall size of graphite ranges from 2µm to 50µm (width) x 1,000µm (length) with the average 20µm x 300µm (large flake). The range in length to 1,000µm is classified in the graphite market as Super Large graphite.

The graphite occurs within “schistose micro-gneiss, with thin intricately intercalated schistose layers of quartz-feldspar-graphite and scattered amphiboles”.

Some Other Wildhorse Plain Graphite Targets

A405

Graphite was reported in drill holes as a part of uranium exploration in 1968 by Kerr McGee.

Hole A405/2 graphite flakes were reported from 32 to 56 metres, within altered dolomites. Hole A405/3 medium crystalline graphite was reported over a few metres.

Hole A405/3A common graphite flakes were reported from 28 to 41m downhole. Hole A 405/3B trace graphite flake from 41 to 52m (EOH)

Wilklow

Graphite was reported during exploration for uranium. Historically a sample of graphitic schist was taken from the surface that “ yielded 4.25% of flake graphite which assayed 39.25% carbon.

Two holes were drilled in 1952, both intersected graphite within clay-rich weathered quartzite.

A 1991 drill hole testing a IP/resistivity anomaly intersected high grade metamorphic rocks with graphite. The IP anomaly was attributed to the graphite. A sample submitted for petrology reported “moderate amounts of graphite forming well developed flakes up to 0.5mm in length.” The metamorphic grade of these rocks is conducive to graphite flake development.

Calkookra

Calkookra was a historic underground copper mine. In 1968 exploration for uranium identified graphite in an exploration drill hole. Although no qualitative work was performed on the graphite, the metamorphic grade of the surrounding rocks (mylonite and amphibolite) is encouraging for large flake development. A copper enriched sample was submitted for petrology in 1983, it was reported as having 5% graphite with flakes of approximately 0.3mm in length.

Archer Graphite – Summary

Known Knowns

==> picture [11 x 12] intentionally omitted <==

  • Exploration is in the formative stages having started in April 2011.

  • Large prospective land bank >900km[2] .

  • Exploration has consisted of rock chip sampling, RC drilling and detailed petrology.

  • Through literature searches Archer identified numerous graphite prospects – Sugarloaf, Campoona – Campoona South, Grid 2, A405, Mt Shannan, Council Pit, Wilklow, Miltalie, Calkookra, Ben Buy and others.

  • Metamorphic grade is important for flake size – weathered gneisses and marbles appear most prospective.

  • Sugarloaf Exploration Target of 24-37Mt grading 10-12% C is contained within the western limb which is open along strike to the north. Deposit outcrops and averages 40m in true thickness. Graphite mostly fine averaging around 100µm. Exploration Target likely to increase with further exploration via strike extensions and the inclusion of the eastern limb.

  • Petrology identified flake graphite at Campoona -Campoona South (avg 250-300µm), and Council Pit (avg 300µm). Historic exploration pre-Archer records large flake graphite at Calkookra and Wilklow. Other graphite bodies reported graphite in drilling but were not assayed or assessed.

  • EM offers an excellent exploration tool.

  • The limited drilling to date has been via RC hammer drilling which has led to breakage of graphite.

  • Sugarloaf flotation tests in progress - first tests showing ≈ 50% C in first rougher concentrate indicating potential for >80%C concentrate following multiple cleaning stages.

Known Unknowns

  • Metallurgical test work has commenced to determine the graphite products that can be produced. Samples from

  • Sugarloaf, Campoona South, Campoona and Grid 2 being evaluated in overseas graphite facilities.

  • There is a high likelihood that more graphite prospects will be discovered in this emerging “graphite province ”.

==> picture [16 x 17] intentionally omitted <==

Magnesium carbonate (MgCO3) was deposited as a chemical precipitate in shallow, marginal marine lagoons and mudflats, and occurs predominantly as cryptocrystalline particles 1–5 µm in size. 86 separate magnesite interbeds within the Skillogalee Dolomite have been recorded at Leigh Creek.

Magnesia (MgO) is produced by heating magnesite typically above 1000[o] C. Magnesia occurs in three forms:

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 used for the production of refractory bricks.

3. Electrofused magnesia (EM) is produced by melting CCM to 2,800 - 3,000[o] C to produce crystalline magnesia used primarily in arduous steelmaking applications.

Magnesite / magnesia products are widely used across a number of high growth industries and widely used in high technology consumer goods

Leigh Creek Magnesite

Calcining Test Work

  • Calcining tests to 1000[o] C on run-of-mine magnesite produced magnesia grading: > 92% MgO

≈ 4.5% SiO2

≈ 0.3% Al2O3 ≈ 0.6% CaO ≈ 0.4% Fe O 2 3

  • To maximise the marketability of magnesia produced the SiO2 level needs to be reduced to ≤3.0% (ideally ≤1.5%) and the magnesia (MgO) increased to ≥95% MgO.

  • Talc - hydrated magnesium silicate H2Mg3(SiO3)4 or Mg3Si4O10(OH)2 accounts for much of the SiO . 2

  • Further test work being undertaken to determine the optimum process flow sheet.

  • Latest flotation tests have reduced pre-calcination SiO2 levels to 1.9% which would translate into a ≈3.6% SiO2 CCM product.

Archer does not underestimate the barriers to entry that exist for new entrants into the extremely competitive magnesia “industrial minerals” market. However, the Company believes that the comparatively modest expenditure needed to attempt to identify the optimum process flow sheet is well worth the risk. Archer is confident that, should this be achievable, considerable value would be unlocked through the ownership of such World Class magnesite resources.

Archer Manganese

Salt Creek manganese

  • Drilling highlighted that manganese occurs in three different rock units:

  • High iron manganese associated with banded iron formation.

  • Fine manganese in weathered pelitic sediments (clays & schists).

  • 5mm fine manganese nodules within transported silica-rich sand.

  • The manganese units comprise two limbs of an overturned syncline with a western limb consisting of outcrops of high-iron manganese and an eastern limb of manganese and silica-rich manganese adjacent to quartzite/leached BIF.

  • +0.5mm grades 20-25% MnO with recoveries to 30%.

  • Strike length consists of 4kms (confirmed) and up to 10kms based on regional historic sampling.
