Feysville Gold Project
Astral Resources 100% interest
The Feysville Gold Project is located within the north-north-west trending Norseman – Wiluna Greenstone Belt, within the Kambalda Domain of the Archean Yilgarn Craton, approximately 14km south of the KCGM Super Pit in Kalgoorlie.
Feysville hosts an MRE of 3Mt at 1.3g/t Au for 116koz of contained gold1 at the Think Big deposit, providing a foundation for the project to potentially become a source of satellite ore feed to a future operation based on Astral’s flagship Mandilla Gold Project.
Significant gold and nickel mineralisation occurs throughout the belt, including world-class deposits such as Northern Star Resources’ (ASX: NST) Golden Mile Super Pit in Kalgoorlie and Gold Fields’ St Ives Gold Mine south of Kambalda.
Locally, Feysville has been interpreted to contain upthrust ultramafics, emplaced within a sequence of volcanic sediments (the Black Flag sediment group), granitic intrusions, mafic basalts, gabbro and andesite. A map of the Feysville Gold Project identifying tenements and deposits/prospects on local area geology is set out in the Figure below.

1 Feysville JORC 2012 Mineral Resource Estimate: 0.6Mt at 1.1g/t Au for 20.2koz Indicated Mineral Resources and 2.3Mt at 1.3g/t Au for 95.6koz Inferred Mineral Resources (refer to ASX Announcement dated 8 April 2019).

Gold deposits along the belt are contained within a major structural corridor centred on the Boulder Lefroy fault, which controls regional uplift and folding of a lower sequence of mafic-ultramafic rocks (purple and green) surrounded by an upper sequence of volcano-sediments (blue and yellow). Feysville contains the lower mafic-ultramafic sequence of rocks in the core of the project area, with the Boulder Lefroy fault interpreted to pass along the western flank of the project.
In late 2016, a ground magnetic survey identified a new shear zone of more than 7km in length, referred to as the Ethereal Shear Zone.
Astral Resources has recently lodged an application for a Mining Lease at Feysville.
A map of the Mining Lease Application Plan illustrating key deposits and other features is set out below.
Think Big
Think Big represents a robust, higher-grade core of NW-trending near surface gold mineralization within the fragmental volcanic unit on and east of the Ethereal Shear Zone.
Mineralisation extends for approximately 500 metres along strike and typically 10 metres across strike
Several additional sub-parallel zones of mineralization occur within the fragmental unit sub-parallel and up to 50 metres east of the Ethereal Shear Zone.
A plan view of the geology of Think Big Prospect at 280 metre RL illustrating the plunging fold east of the Ethereal Shear Zone is set out below.
A composite long section of gold mineralisation at Think Big is set out below. Mineralisation east of the Ethereal shear zone is contained within a moderate SE-plunging shoot at least 200m in strike extent which remains open down-dip and down-plunge. Many drill holes have multiple intersections which aggregate into broad, moderate gold grade intervals with potential for underground mining.
A schematic cross-section of Think Big at the location identified in the map above illustrating the deposit geology and principal zones of gold mineralisation to the east of the Ethereal Shear Zone, including the overlaying supergene-enriched gold zone, is set out below.
Saintly
At Saintly, mineralisation extends for at least 160 metres along the Ethereal Shear Zone.
Like Think Big, shallow supergene enriched gold mineralisation sits atop bedrock mineralisation.
Best intercepts include 21 metres at 2.47 g/t Au from 20 metres and 12 metres @ 5.8 g/t from 16 metres.
Rogan Josh
At Rogan Josh, an at-surface target of size range 300,000 to 350,00 tonnes at 2.0 to 2.5 g/t Au is currently interpreted.
Saintly South
At Saintly South, an intercept of 4 metres at 49.67 g/t Au from 68 metres to the bottom of hole has been recorded.
Kamperman
At Kamperman, an intercept of 13 metres at 8.31 g/t Au from 24 metres to the bottom of hole has been recorded.
Ethereal
At Ethereal, intercepts of 10 metres at 9.1 g/t Au and 6 metres at 9.76 g/t Au have been recorded.
Dalray
At Dalray, an intercept of 6 metres at 9.08 g/t Au has been recorded.
Hyperno
At Hyperno, an intercept of 13 metres @ 1.05 g/t Au from 25 metres has been recorded.
