Yilgarn Lithium Project, Western Australia, Australia

The Yilgarn Lithium Project (“YLP”) is a hard-rock lithium project located in the Yilgarn Province of Western Australia.

YLP consists of 16 Exploration Licenses, including 11 granted Exploration Licenses and 5 pending Exploration License Applications, covering 747 km2.

The YLP Exploration Licenses are located over extensions of known lithium-fertile belts, proximal to granites known to act as sources of LCT pegmatites, within covered areas of Archean Yilgarn Craton and hold the potential for hard-rock spodumene (lithium mineral) bearing pegmatite mineralisation, similar to that found at Greenbushes and Mt Marion. Emphasis in area selection guided targeting to areas of shallowly-concealed bedrock because of the long history of prospecting in much of the Yilgarn Province.

Land Management

YLP consists of 11 granted Exploration Licenses and 5 pending Exploration License Applications. E 77/2384 (Windarling) and E 63/1815 (Caranning), overlap conservation reserves and have been referred to the Department of Biodiversity, Conservation and Attractions for the Minister’s comment and recommendations. E28/2743 (Salmon), E63/1877 (Dundas North), and E28/2732 (Junction North) are currently being processed through the Native Title future act process. E77/2384 (Windarling) needs to be processed through the Native Title Act future act process. There is currently no overlapping native title claim and if no claim is lodged prior to grant it is expected that there will be no heritage agreement in relation to this tenement.

Exploration

A Phase 1 drilling program at YLP was completed in December 2017 and the geochemical results were received and interpreted during the March 2018 Quarter.

Regional Location of the Drilling

The results indicate the presence of Lithium-Caesium-Tantalum (LCT) pegmatites, under cover in at least 3 Licenses.

Anomalous levels of Li and associated LCT pegmatite pathfinder elements (i.e. Cs, Nb, Rb, Sn, Ta) were intersected in holes in the E63/1826 (Dundas), E63/1814 (Bedonia) and E63/1813 (Ten Mile) licenses.  Elevated levels of LCT pegmatite pathfinder elements were also intersected in several holes at Snomys. 

Anomalous LCT pegmatite pathfinders were identified at the Dundas License in and around the intersected weathered pegmatites in both aircore drill hole traverses, approximately 1.6km apart. Airborne magnetic data used to target the Dundas area indicates that the prospective zone is open to the north and south of the current drilling.

LCME believes that the Dundas area is the southern part of a buried LCT pegmatite corridor.  LCME currently holds the Licenses to the north of the current Aircore lines over an area covering approximately 40km of the prospective granite contact zone and potential LCT pegmatite corridor. 

E69/3540 (Esmond) has now been covered with a 1,350 line-km detailed airborne magnetic survey. Analysis of the data is ongoing, but first results of the analysis indicate the licence is prospective with further evaluation warranted. Selected targets within this licence will be evaluated with aircore drill traverses, because transported cover likely precludes effectiveness of surface geochemistry as a search tool. The region of the licence is generally regarded as being prospective because some of the granites display strongly elevated Rb values in open-file State geochemical data sets, and display appropriate signatures within the published State aeromagnetic data.
