Kathleen Valley Lithium Project

OPPORTUNITY

The 100%-owned Kathleen Valley Lithium Tantalum Project has rapidly emerged as a Tier-1 battery metals asset with excellent grade and scale in one of Western Australia’s best mining districts.  

With a Pre-Feasibility Study already completed, two successive resource upgrades delivered in the past nine months and a Definitive Feasibility Study expected to commence this year, Liontown has positioned itself at the forefront of a new generation of lithium developers.

RESOURCES AND EXPANSION

Liontown recently announced an interim MRE upgrade for the Kathleen Valley Project of 139Mt @ 1.3% Li2O and 140ppm Ta2O5, confirming the project’s status a world-class lithium deposit. 

Liontown has a strong track record of consistently meeting or exceeding targets and the Company expects to continue this fast-paced development beyond 2020 – as reflected by the following major milestones achieved in less than 18 months:

NEXT STEPS

Liontown’s objective for 2020 is to further enhance PFS project economics and commence a Definitive Feasibility Study. Numerous opportunities exist due to a significantly larger resource, ongoing metallurgical test work to design an optimal process flow sheet to maximise grade and recoveries of both lithium and tantalum, together with assessing the inclusion of underground Ore Reserves.

Recent drilling results have included multiple individual metres grading >5% and intercepts of up to 3.8% Li2O over 21m and 3.4% Li2O over 7m, further demonstrating the continuity of exceptionally high-grade mineralisation at Kathleen Valley – Click here to view the ASX Announcement. 

A further MRE is scheduled for completion in March / April  2020 which will include these high-grade results, and both open pit and underground resources are anticipated to deliver the best outcome for the DFS by providing the opportunity to bring forward the mining of higher grade mineralisation.

The size and grade of Kathleen Valley now provides multiple opportunities to significantly enhance the project’s financial returns, including:

  • High potential for a larger Ore Reserve;
  • Access higher-grades earlier;
  • Lower opex;
  • Tantalum by-product;
  • Downstream opportunities

LOCATION

Kathleen Valley is located on granted Mining Leases in an established and well serviced mining region, approximately 680km north-east of Perth, WA (Figure 1). 

The Project is readily accessible by sealed highways which connect with mineral exporting ports at Geraldton and Esperance. Other infrastructure located close to the Project includes a power line, a natural gas pipeline and mine camps with sealed airstrips capable of taking 100 seat jets.

GEOLOGY

The Kathleen Valley Lithium-Tantalum Project is located on the western edge of the Norseman-Wiluna Greenstone Belt within the Archaean Yilgarn Craton of Western Australia. The belt consists of dominantly mafic and ultramafic volcanics as well as considerable volumes of clastic sediments, minor felsic volcanics, and differentiated gabbros.  The greenstones in the Kathleen Valley area have been metamorphosed to upper greenschist-lower amphibolite facies metamorphic grades and include tholeiitic lavas, differentiated gabbroic sills and ultramafic chlorite schists.

Lithium mineralisation is hosted within spodumene-bearing pegmatites, which are part of a series of LCT-type rare metal pegmatites that intrude mafic and sedimentary rocks in the region.

Seventeen mineralised pegmatites have been identified at the Kathleen Valley Project hosted by two, outcropping, NW/SE trending pegmatite swarms – a shallowly-dipping, north-eastern swarm (Kathleen’s Corner), which contains approximately 80% of the pegmatites, and a steeper dipping south-western swarm (Mt Mann). The two swarms are interpreted to merge at depth to form a single, thick, moderately dipping mineralised body which remains open down-dip and along strike.
