The Higginsville Joint Venture is managed by Argonaut Resources NL (51% earn in up to 80%) with Loded Dog Prospecting and covers a large tenement package in the Eastern Goldfields of Western Australia.

The Higginsville Joint Venture is exploring for gold and nickel within the Norseman-Wiluna Belt, a belt of ancient rocks endowed with gold mineralisation that lies within the broader Yilgarn Craton where approximately 70% of Australia's historical gold production has been mined.

The Higginsville Project is situated nine kilometres south of the Higginsville (+2.5Moz) gold mining camp that lies between St Ives (+15Moz) and Norseman (+10Moz) gold mining districts (Figure 1).

Gold Exploration

Argonaut's two primary goals in securing the earn-in agreement are to firstly, explore for near-surface oxide gold in areas with historic shallow drilling results and secondly, to target deeper primary gold mineralisation at depths previously untested by drilling. 

In 2017 Argonaut conducted reverse circulation drilling at the Amorphous and Footes Find gold prospects that are located five kilometres to the south from the operating gold mill at Higginsville.

Amorphous Prospect

The Amorphous prospect contains a 1 g/t gold contour along a 1 kilometre strike length with gold mineralisation typically hosted in an altered shear zone within an easterly dipping gabbroic unit (Figure 2).

The gold envelope dips to the east at approximately 60 degrees, rather than 80 degrees as previously interpreted thus improving conceptual open-pit geometry by lowering the theoretical stripping ratio.

Highlights from drilling intercepts at Amorphous includes:

  • 8m at 2.07g/t Au from 26m in drill hole AMC0007, including 2m at 7.94g/t Au from 28m
  • 9m at 1.21g/t Au from 71m in drill hole AMC0010, including 2m at 3.78g/t Au from 73m
  • 5m at 4.03g/t Au from 21m in drill hole AMR0013, including 2m at 10.37g/t Au from 22m
  • 8m at 3.27g/t Au from 17m in drill hole AMR0015, including 3m at 9.6g/t Au from 21m

Footes Find Prospect

Rock chip sampling within an open pit at Footes Find returned high grade gold with samples returning up to 17.25 g/t gold. Drilling confirmed good mineralised widths with high grades.

Highlights from drilling intercepts at Footes Find include:

  • 4m at 5.02 g/t Au from 40m in drill hole FFRC001
  • 8m at 1.68 g/t Au from 30m in drill hole FFRC002
  • 7m at 2.13g/t Au from 28m in drill hole FFP0010

Additional drilling at the Footes Find prospect is warranted to confirm continuity of grades and widths along strike.

Island Prospect

The Island prospect is defined by a >10ppb gold anomaly over a 1,200 metre by 400 metre area that was historically defined from shallow auger drilling and includes surface rock chips returning up to 0.34 g/t gold.

The anomaly sits directly over a major northwesterly orientated fault which terminates the north-south trending greenstone package that hosts the Higginsville gold deposits such as Trident, Poseiden South, Fairplay and Corona (Figure 3).
