Operational Highlights
Estimated in the PEA:
Mr Martin McFarlane, President and CEO states, “We are very encouraged by the positive results from the Woxna PEA, which demonstrate a very low capital, low operating cost project that generates good returns for shareholders. Flinders– on-going sales of stockpiled flake graphite has enabled us to establish relationships with consumers, providing a firsthand view of the graphite market demand in Europe. The PEA assumes conservative graphite prices and requires an initial capital investment that is an order of magnitude lower than peer projects.”

“The PEA demonstrates Woxna–s strengths in the flake graphite market, which include its full operating permit allowing immediate restart, an established processing plant and related mine infrastructure, and close proximity to the European markets. With Canadian $12.3 million cash on hand as at July 31 2013, Flinders has a substantial portion of the start-up capital available. We thank GBM and our other consultants for their input into this exciting project.”
The PEA was prepared by GBM Minerals Engineering Consultants of the United Kingdom (Mineral Project Engineering), with contributions from Golder Associates AB of Sweden (Mining Plan), Reed Leyton Consulting (Mineral Resource), Aminpro Metallurgical Services of Chile (Metallurgical Test Work and Process Design), Tailings Consultants Scandinavia (TCS) (Tailings Facility Design) and Woxna Graphite AB/Flinders Resources Limited (Project Owners).
MINERAL RESOURCES
Woxna Graphite AB, Flinders– 100% owned Swedish subsidiary, owns 4 mining concessions over graphite deposits (Kringel, Gropabo, Mattsmyra and Mansberg – the Woxna Project) located along a 40km trend in central Sweden. The PEA considers only one of these deposits, the Kringel deposit. The partially mined Kringel deposit lies adjacent to the processing plant, tailings dam and related infrastructure, and is fully permitted for an immediate restart. Woxna is currently reprocessing graphite and last mined graphite in 2001.
The Kringel mineral resource estimate was completed by independent geologist, Mr. Geoffrey Reed of Reed Leyton Consultants in April 2012. The resource estimate was recalculated for the PEA using more accurate drill hole collar locations and this has resulted in a moderately increased resource tonnage with higher grades.
The recalculated mineral resource at Kringel is drilled across an area approximately 1200 metres (“m”) length by 100m to 200m width. Mineralization was intersected on all drill sections and continues to at least 150m below the surface. Mineralization strikes east-west, and dips between 60 and 80 degrees to the south. Mineralization is present as four main and five smaller mineralized bodies. The thickness in the section of the plane is usually more than 10m, but varies between 5m and more than 15m. Mineralization at Kringel remains open along strike and at depth, and geophysical data suggests potential for significant expansion.
A total of 90 diamond drill holes for 6,581m drilled between 1988 and 2012 were included in the current mineral resource estimation. Hole spacing is on a 50 metre by 50 metre drill pattern. A lower cut-off grade of 7% graphite was used as the base case to calculate the resource. Flinders considers the cut-off grade to be conservative.
Table 1 – Kringel Mineral Resource Estimate (7 % Cg lower cut-off grade)
Cautionary Note: Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The PEA is preliminary in nature and there is no certainty that the PEA will be realized.
In addition to the Kringel graphite resource, the Gropabo, Mattsmyra and Mansberg flake graphite deposits contain historic resources. These will continue to be classified as historic resources until Flinders has the opportunity to upgrade them to NI43-101 standards. These historic resources are not included in the economic analysis of the PEA.
MINING
The PEA estimates for the life of the mine (“LOM”):
Golder Associates AB (Golder) completed the mining study for this PEA. Pit optimisation, pit design and mine production schedules were performed using industry standard Gemcom Whittle 4x optimisation software, Maptek Vulcan and Gemcom Surpac mine planning software using only graphite under Measured and Indicated mineral resources categories within the provided resource model. The model produced a quantity of mineralized material and waste tonnes, distributed over the life of the mine. Inferred resources were not used in the mining or economic models produced in the PEA.
The model shell was then used to generate operational pit designs. Two distinct open pits were designed around the Whittle shells. The pits included haulage ramps located on the south wall of the pits.
Table 2: Materials contained in proposed pits
The pits were then scheduled over the LOM by months for the first year, quarters for years 2 and 3 and then annually for the remainder of the life of the project. The Whittle production schedule was set at 100 000 t/a ROM however, for the purposes of economic modelling, the mine throughput was increased to 155,000 t/a ROM, and therefore the Whittle production schedule was accelerated on a pro rata basis accordingly. The waste to mineralised material ratio increases over time due to the depth of the pits and designed strip ratios until the final years when the benches are predominantly mineralised material.
The Company plans to use contract mining and the operating costs were derived from contractor quotes obtained by Golder.
PROCESSING & RECOVERY
The PEA estimates:
The Woxna project has an existing graphite processing plant which was last fully operated in 2001. A comprehensive metallurgical test work programme by Aminpro led to a new process flow sheet designed by Aminpro and GBM. This flow sheet predicts a significant improvement in quantity, grade and graphite flake size distribution compared to historic production. Engineering under the PEA proposes utilising as much of the existing facilities and infrastructure as possible in line with the new design, to minimise the initial capital cost and enable production to commence in the shortest possible time.
The process flow sheet incorporates conventional mineral processing technology starting with 2 stage crushing of the run-of-mine material followed by grinding in the existing rod mill. The ground product is treated by flash and rougher flotation to maximise the recovery of large flake. The rougher tailings are treated in a scavenger flotation circuit to maximise recovery. The flash and rougher concentrates then undergo 2 stages of regrinding and cleaner flotation while scavenger concentrate has 3 stages of regrinding and cleaner flotation. Most of the flotation section uses new equipment. 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.
The nominal throughput of the plant is 155,000 tonne/year based on the maximum rate that can be milled in the existing rod mill. There is potential to significantly increase throughput by using an existing re-grinding mill as a ball mill in the primary milling circuit along with commensurate expansions of the flotation, drying, screening and packing sections. An expansion of capacity would be considered once markets permit.
GRAPHITE MARKETS, PRICES & SALES REVENUE
The European graphite market is estimated to consume approximately 20% of the global demand for natural flake graphite of circa 500 000 tonnes/year. Today more than 90% of Europe–s graphite demand is imported, mainly from China.
The Woxna graphite project will primarily target the European graphite market due to its proximity to Sweden, short transit times and low transport costs. At 16,600 tonnes/year, the design production volume in the Woxna PEA is deliberately sized so that graphite sales may be readily absorbed into the European market without creating an oversupply situation. Further expansion of the Woxna graphite project is possible and will be evaluated when European market conditions permit.
Graphite prices have risen considerably since the Woxna mine was last operated in 2001. In 2010, following a long period of flat prices, graphite prices, particularly for flake grades, rose rapidly as a result of a surge in demand due to restocking, growth from China and lithium batteries. Simultaneously, the imposition of taxes and permits on Chinese graphite exports restricted supply. Graphite prices peaked in 2012 and eased to today be approximately double the level seen in 2001. Graphite market commentators predict that prices may be approaching the bottom and with signs of economic recovery in the USA and the worst of the recession behind Europe, graphite prices may again strengthen.
Graphite is not an openly traded mineral with prices negotiated privately between customers and producers under spot or term contracts. The sale price used in the PEA was based on graphite prices published by Industrial Minerals magazine (“IM”).
It has been common practice to use a 24 month trailing average graphite price in graphite PEAs. The Woxna PEA utilized a 12 month trailing average graphite price so as to exclude the peak price period occurring in 2011/12. Applying Woxna–s planned product distribution to IM–s 12 month trailing average graphite prices produces an average selling price of $1,199/tonne for the Woxna PEA. This selling price is considered to be conservative when compared to the 24 month trailing average graphite price of $1,548/tonne or prices used in other graphite project PEAs.

INFRASTRUCTURE AND PERMITS
The Woxna mine site is fully permitted and has a partially exploited open pit, waste rock dump areas, mine site roads, processing facility, tailings management facility and clarification ponds. Woxna is connected to public roads and has a sufficient water and electricity supply.
Modest upgrades are contemplated to the infrastructure with the most significant change being the upgrade of the tailings storage facility to both increase its capacity and improve environmental performance to current best practice. As this work has to be performed when the ground is not frozen, this task is the critical item in a re-start schedule.
The Woxna project is fully permitted to extract 100,000 tonnes / annum of mineralised rock for processing. The PEA proposes increasing production to 155,000 tonnes / annum of mineralised rock. The PEA assumes that production can commence under the existing permit (concession) while an increase in capacity is sought. Expanded capacity is assumed in the second year once the permit is obtained.
