About Lithex Resources Limited
Lithex Resources Limited is an exploration company now focused on unlocking the resource potential of Australia's graphite-rich provinces.
Lithex Resources Limited listed on the Australian Stock Exchange (ASX: LTX) on 17 May 2011. At this point, the Company was focused on the exploration and development of lithium, tantalum, tin and rare earths resources in the East Pilbara and Gascoyne regions of Western Australia.
A shift in company focus and strategy came in December 2012 when Lithex Resources successfully acquired Far North Minerals Pty Ltd. The transaction expanded the Company's project portfolio, bringing on-board a tenement package covering 533km2 of land in Australian regions considered highly prospective for graphite.
The newly acquired graphite plays have taken top rank in Lithex's suite of projects, with the Company now intently focused on graphite exploration in Australia. Immediate attention has been directed towards exploration of the Munglinup Graphite Project in far south WA with work on the Plumbago Graphite Project in northern NSW also in the near-term pipeline.Lithex's existing mineral projects in the East Pilbara and Gascoyne regions of Western Australia are now a secondary focus for the Company.
Like the Munglinup Graphite project in WA, the Plumbago Graphite Project is a key project for Lithex. The Plumbago Project is located in the Undercliffe Falls area in northern NSW, approximately 45 kilometres north of Tenterfield. The tenement area is hosted within Permian age Gilgurry Mudstones, which have been altered via metamorphic processes associated with intrusion of the adjacent granitic rocks. This host rock is found over a six kilometre strike length within the tenement.
The project area also contains 10 historical graphite occurrences, with three documenting production in the early 1900s (estimated total production of 3,000 tonnes). The known graphite localities include the George Creek, Falls Creek, Nicklaus, Half Moon, Circular Quay Gully, and Hutt Spur occurrences. These are historical occurrences, with no recent systematic graphite exploration program conducted prior to Lithex's acquisition.
Lithex is in the early exploration phase at its 100%-owned Plumbago Graphite Project.
Amorphous and coarse flake graphite was visually identified during an initial field geological mapping and sampling program. Initial rock chip samples were taken for laboratory analysis and assay results found grades of up to 23% Total Graphitic Carbon (TGC). Results ranged between 1.4% and 23% TGC, with an average of 10.6% TGC.
Metallurgical testing of samples will more accurately determine the exact flake profiles and physical characteristics. Airborne Electromagnetic (EM) surveys will be undertaken as a next step, to identify the strongest graphite targets for further sampling, geological mapping and future drilling activity. The exact dates for when these will be conducted, are yet to be determined.
The Eyre Point Project is considered a pipeline project for Lithex. It is high up on the list of priorities; however the Company is looking to expand the project before commencing a major work program.
Eyre Point is located on South Australia's Eyre Peninsula, within the world-renowned Gawler Craton. The Eyre Peninsula is recognised as a world-class graphite province and has recently been dubbed 'the Pilbara for graphite.' The area is characterised by a high metamorphic grade belt of Proterozoic rocks – favourable settings for the development of coarse flake graphite.
The Eyre Point Project is located approximately 20km from the Uley Graphite Mine. Hosting 6.6Mt at 8.7% Total Graphitic Carbon (TGC), the Uley Graphite Mine is one of the largest coarse flake, high-grade graphite deposits in the world. Others neighbours include Lincoln Minerals Ltd (ASX: LML) and Archer Exploration Ltd (ASX: AXE).
At this stage, the Eyre Point Project comprises only one tenement – the Exploration Licence was granted to Lithex in January 2013. Initial field work has been carried out on the project area and planning is underway for further exploration activity, including airborne Electromagnetic (EM) Surveys.
The Munglinup Graphite Project is the flagship asset in the portfolio and is 100% owned by Lithex. It covers a total area of 406km2 and comprises five tenements – four consolidated and one under application. The one tenement Exploration Licence under application contains the Young River Graphite Deposit – an exciting graphite prospect that is linked to historical graphite occurrences.
Munglinup is approximately 100km west of Esperance, in an area of far south Western Australia considered to be highly prospective for graphite mineralisation. It is located along strike and is contiguous with the eastern and southern sides of the nearby Halberts Main Munglinup Deposit. Halberts is owned and operated by Graphite Australia Ltd, and with a Resource Estimate of 1.47Mt @ 18.2% fixed carbon, it has the potential to be WA's first commercial graphite mine.
Lithex is in the early exploration phase at its 100%-owned Munglinup Graphite Project.
Electromagnetic (EM) surveys have been carried out over the project area for the purpose of identifying target anomalies for future drilling activity. Surveys found a strong north-south trending graphitic anomaly. This EM result is consistent with the area of sub-cropping graphitic gneiss recently identified near the north end of tenement E74/518 by an independent geological consultant. A graphitic gneiss float was also located 700m south of the sub-cropping area.
Initial rock chip sampling has also been undertaken in the field at the areas of graphitic outcropping. Laboratory test work interpreted the samples to contain between 8.6% and 23.1% Total Graphitic Carbon (TGC).
The relevant Government approvals have now been received for drilling activity to proceed. The first round of drilling involves six diamond drill holes, targeting the strongest graphitic anomalies which have been identified by EM survey analysis.
The Moolyella Project (90-100% LTX) is located in the East Pilbara Goldfield region, within the highly mineralised Achaean Pilbara Craton. It is approximately 23km east-north-east of the township of Marble Bar.
The tenements cover the Moolyella Tin Field – an area discovered in 1898 and known to contain deposits of rare metals (tin, tantalum and lithium) and rare earths (lanthanides). In the period between initial discovery and 1986, mining activity at Moolyella was focused and ongoing, but since then, only small-scale intermittent mining has been carried out.
A comprehensive exploration program is required to prove up the known deposits of rare metals and rare earths, to locate new alluvial deposits and to explore for the primary hard rock deposit from which these alluvial minerals have originated.
History of the Moolyella region
Tin mining operations at Moolyella were largely continuous from 1898 to 1986. Endeavour Resources Ltd carried out exploration for alluvial, eluvial, deep lead and pegmatite-hosted tin/tantalum mineralisation between the years of 1965 and 1985. Several substantial alluvial and eluvial tin/tantalum deposits were identified.
The first large-scale mining operation occurred after Endeavour Resources Ltd purchased all of the Moolyella tenements and the treatment plant in 1978. These large-scale mining operations continued till 1986, but where then closed due to the fall in tin prices in late 1985.
The Shaw River Project (90% LTX) is located in the East Pilbara Goldfield region, within the highly mineralised Achaean Pilbara Craton. The project is centred on the Shaw River Tin Field, situated approximately 50km southwest of the township of Marble Bar.
Historical exploration and mining activities have been carried in the project area, however modern-day exploration for alluvial and hard rock pegmatite deposits containing lithium, tantalum, tin and rare earth metals is required to evaluate full potential.
History of the Shaw River Region
The Shaw River Tin Field was discovered in 1890. By 1975, the area had produced a total of 6,585t of tin concentrate. Greenbushes Ltd first acquired leases in the Shaw River district in 1978 and explored for tin and tantalum from 1979 to 1981. Further exploration for tin, tantalum and rare earth metals was then conducted by Joint Venture parties, Greenbushes Ltd and Western Australia Rare Metals Ltd, up until 1987. A mining Feasibility Study was then completed for the project in 1988.
The Pilgangoora Project tenements (90-100% LTX) are located in the East Pilbara region, adjacent to the Pilgangoora Tantalum Field and approximately 120km south-south-east of Port Hedland.
Type 1 pegmatites (Quartz-spodumene-albite-microciine pegmatites) are the primary source of tin and tantalum mineralisation at Pilgangoora. They form north-north-east trending bodies up to 60m thick in greenstones, within an 8km long and 1.5km wide corridor that begins south-south-west of the tenements and extends northwards into the Pilgangoora Project tenements.
The spodumene content of these pegmatites (-25 %) has previously been the focus of evaluation studies by Pancontinental Mining Ltd as a source of lithium concentrates. While it is understood that the pegmatites extend into Lithex's tenements, none of these deposits studied by Pancontinental Mining Limited in that report are located in the Pilgangoora Project tenements. The project therefore requires further assessment by modern-day exploration that specifically targets these lithium pegmatites.
The Pilgangoora Project tenements are accessible by unsealed shire and station roads, various tracks that service abandoned mine workings and pastoral stations.
History of the Pilgangoora Region
The Pilgangoora Tantalum Field was discovered in 1905. By 1947, the field had produced approximately 0.7t of tantalite concentrates from small-scale alluvial operations. Post 1947, larger-scale mining operations were carried out in the area, and by 1975, approximately 50t of high-grade tantalite and some 13t of tin oxide (cassiterite) were produced. Pilgan Mining continued large-scale mining operations between 1978 and 1982, and then continued by the Pilgangoora Mining Venture from 1992 to 1996. These operations produced approximately 140t of tantalite concentrates, from an estimated 800,000 bank m3 (UBCMU) of screened alluvial and eluvial material.
Mining on the tenements within Lithex's Pilgangoora Project has only been carried out by the Pilgangoora Mining Venture. This involved the collection of bulk samples from two creeks as part of its Pilgangoora resource estimation program in 1996.
The project is located 14km to the east of the Furniss graphite mine, east of Albany, in southern Western Australia. No records are available with regard to details of past production, quality or resources.
The graphite at Furniss occurs in a metamorphosed strata-bound sedimentary sequence. The project tenement straddles the mid-late Proterozoic Biranup complex of the Albany-Fraser Orogen and was considered by Anglo American Exploration (Australia) Pty Ltd in 2001 as prospective for base metal mineralisation.
