Moora Gold-PGE-Ni-Cu Project

OPPORTUNITY

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).

PROJECT STATUS

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

  • The 15km long, north-west trending Mt Yule-Felton Corridor located in the  south western part of the Project; and
  • The 7x7km Bindi Bindi Nickel area is located in the central part of the Project.

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:

  • Mt Yule (Figure 5) – a 3.6 x 2.2km, E/W trending gold anomaly (>10ppb) containing multiple plus 100ppb zones with a number of >500ppb Au assays (up to 925ppb). The gold anomalism is associated with highly elevated PGEs (up to 25ppb Pd+Pt), nickel (up to 492ppm) and copper (up to 884ppm).
  • Dalkey – a 1.5 x 2km, N/S trending gold anomaly with assays of up to 127ppb Au. The anomaly is associated with elevated PGEs (>10ppb Pd+Pt) and coincident with a linear magnetic low possibly reflecting bedrock alteration and mineralisation.
  • Horseshoe – a 3 x 2km area containing a number of PGE anomalies (up to 75ppb) associated with elevated gold (>10ppb).
  • Felton – a 2 x 1.5km area of coincident gold (up to 69ppb Au) and PGE (up to 65ppb Pd+Pt) anomalism located at the SW end of the corridor where the trend remains open.

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:

  • 9m @ 0.62% Ni from 0m;
  • 11.5m @ 0.60% Ni from 1.5m; and
  • 21m @ 0.57% Ni from 1.5m.

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.

Next Steps

An airborne electromagnetic (AEM) survey is scheduled to commence in August 2020 and will cover the entire Project area with 200m spaced lines.

Electromagnetic techniques have proven to be effective elsewhere in the region, including Julimar, for defining sulphide bodies and the results of the survey, which are due by late August 2020 will be combined with the auger geochemistry to plan a maiden drilling program.

Liontown will also extend auger sampling across the remainder of the Project area with a focus on yet untested magnetic anomalies.

LAND STATUS

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.
