Liontown secured the Project in 2018 as part of its generative exploration strategy for battery metals, after recognising the potential of this region to host magmatic Ni-Cu-PGE massive sulphides. The coincidence of large mafic/ultramafic intrusions located close to a craton margin is analogous to magmatic Ni-Cu-PGE occurrences elsewhere in the world including the Nova, Savannah and Nebo-Babel deposits in Western Australia.
Liontown’s exploration concept has been validated by Chalice Gold Mines’ discovery of high-grade Ni-Cu-PGE mineralisation in the same geological terrain at Julimar, located ~95km south of the Moora Project (see Figure 1/ ASX:CHN ASX releases dated 23rd March and 15th April 2020).

Geochemical sampling by Liontown has been defined two highly anomalous areas (Figure 2):

Mt Yule – Felton Corridor (Figure 3)
The Mt Yule – Felton Corridor (MYFC) is a 15km long, 2.5km wide, NW trending zone containing a number of gold-PGE anomalies coincident with magnetic highs indicative of near surface, mafic-ultramafic intrusions obscured by shallow cover. The corridor transitions from being gold-dominant in the north-east to PGE-dominant in the south-west.
Specific targets within the corridor include:
The high gold, PGE, nickel and copper results suggest that the interpreted mafic-ultramafic intrusions within the MYFC are analogous to the unit which hosts the Julimar discovery where Chalice Gold recently announced a sulphide-related intersection of 10m @ 1.2g/t Au, 3.5g/t Pd+Pt, 0.1% Ni and 1.3% Cu (see CHN:ASX release dated 9th July 2020).

Bindi Bindi Nickel Area (Figure 5)
Liontown’s auger drilling in the Bindi Bindi area has defined a number of nickel anomalies (up to 1,720ppm Ni) including several which are coincident with mafic-ultramafic bodies mapped by government geologists.
The potential for nickel within the Bindi Bindi area was originally identified by Poseidon Limited in 1968 (see LTR: ASX release, 16th April 2020) with shallow RAB drilling returning a number of significant intersections including:
The area drilled by Poseidon is coincident with Liontown’s northern-most nickel anomaly (Figure 5) and the intersections were reported to be hosted by strongly weathered, oxidised ultramafic rocks. Poseidon interpreted the elevated nickel values to be related to primary sulphides at depth based on the steep orientation of the mineralised zones and anomalous (>300ppm) copper nearby.

Preliminary data from Liontown’s recently completed Airborne Electromagnetic (AEM) survey has defined multiple late time responses possibly indicative of sulphide zones hosted by fresh bedrock beneath transported cover. The EM responses are largely within the previously defined 15km Mt Yule - Felton Au- PGE corridor where multiple geochemical anomalies are coincident with magnetic highs interpreted to be caused by shallow mafic-ultramafic intrusions.
LTR now plans to follow up the AEM with ground-based EM surveys in preparation for a drill program in late 2020.
The Moora Project comprises 3 contiguous, granted exploration licences (E70/5217, E70/5286 and E70/5287) which form a 467km2 area located ~150km NNE of Perth, Western Australia.
All ELs are held by ERL (Aust) Pty Ltd, a wholly owned subsidiary of Liontown Resources Limited.
The Moora Project is largely underlain by freehold properties used for broad acre cropping and livestock rearing. Liontown has negotiated access agreements over 7 of the larger properties which cover the main geophysical anomalies and is in discussions with other landowners.
Liontown has signed a Heritage Agreement with the South West Aboriginal Land and Sea Council Aboriginal Council who act on behalf of the Yued Agreement Group.
