The Kathleen Valley Lithium 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 mafic and ultramafic volcanics with considerable volumes of clastic sediments, minor felsic volcanics and differentiate 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 lithium-caesium-tantalum (LCT)-type rare metal pegmatites that intrude mafic and sedimentary rocks in the region.Twenty 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 90% 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.Most of the lithium is contained within spodumene. Small, isolated zones of petalite mineralisation have been observed in the north-western part of the deposit (this material equates to <0.5% of the resource samples).The mineralisation is contained within pegmatite veins that are readily distinguished from the surrounding rocks. Sectional interpretation and wireframing indicates good continuity of the interpreted pegmatite veins both on-section and between sections. The confidence in the grade and geological continuity is reflected by the assigned resource classification.Twenty lithium mineralised pegmatites have been identified at the Kathleen Valley Project which extend from surface to a depth of 640 m.At Mt Mann, two steeply-dipping (-70° west) pegmatites have been drilled over a strike length of 1,200 m and to a vertical depth of around 300 m to 400 m. The two pegmatites are up to 35 m thick and have average thicknesses of 9 m and 11 m.At Kathleen’s Corner, 18 sub-horizontal pegmatites have been drilled over an area of 1,800 m by 1,300 m. These pegmatites outcrop in the northeast and are up to 40 m thick with an average thickness of 8 m. The pegmatites coalesce and merge with the Mt Mann pegmatites at approximately 300 m to 400 m below surface to form a single, thick (35 m to 75 m) mineralised body that extends for a further 600 m to 700 m down-dip.
