The Windimurra project (100% owned) is situated in the Windimurra mafic igneous complex along strike from the Canegrass discovery (4.5m @ 1.3% Ni, 1.3% Cu and 0.10% Co from 251m).

Location and Tenure

The Windimurra project consists of a single exploration licence (E58/532) located 70 km southeast of Mount Magnet, in the Murchison Region of Western Australia and covers an area of approximately 31 km2 within the Murchison Mineral Field. Access to the project area is from Mount Magnet along the sealed Mount Magnet-Sandstone Road, then onto the well maintained, unsealed Youanmi road which passes through the northeast corner of the tenement. Minor station tracks and fence lines provide additional access.


Geology is dominated by the Windimurra Igneous Complex, which is a large differentiated layered ultramafic to mafic intrusion emplaced within the Yilgarn craton of Western Australia. The Windimurra mine sequence is in the Eastern Lobe intrusion on the eastern side of the Shepherds Discordant Zone (SDZ) and the vanadium mineralised layers within it occur at the top of the Lobe sequence. The Windimurra mine sequence dips westwards beneath the Western Lobe intrusion at about 35°, following the SDZ down dip to the west, and passing under E58/532 at depth. The surface trace of the SDZ and mine sequence on its eastern side outcrop for tens of kilometres to the north and south of the Windimurra mine. At its closest point, the outcropping SDZ lies about 500 metres east of the northeast corner of E58/532. A Ni-Cu-Co-PGE discovery by BlueBird Battery Metals to the south of the Windimurra project area has demonstrated the existence of potential for nickel/copper mineralisation within the project area.

Previous Exploration

From 2002 to 2015, the area covered by E58/532 formed part of much larger tenement packages operated by Apex Minerals NL, Maximus Resources Ltd and Flinders Mines Ltd (Flinders). While the wider area had substantial work done, only a small amount overlaps the current tenement area.

Most recently (2010-2015), Flinders explored the area as part of their Canegrass Project, specifically their tenement E58/359, which overlaps part of E58/532. Of particular interest, Flinders collected 48 soil samples, as part of a targeted exploration program, that fall within E58/352. A discrete northeast trending coincident copper, nickel, chrome and vanadium anomaly was highlighted but was not followed up.


Several exploration targets have been identified including:

  • nickel-copper-cobalt-platinum group elements mineralised Western Lobe basal units at depth ▪ structurally remobilised nickel-copper-cobalt sulphides above the fragmented SDZ
  • Ironstone scree deposits at surface that may include sulphide gossans
  • a rounded magnetic anomaly in the north, which may be a mineralised gabbro plug like Bluebird Battery Metals’ nickel-copper-cobalt-chrome mineralised Corner Well Gabbro
  • linear magnetic ridges parallel to the SDZ, which may be structural repetitions of Atlantic’s underlying Eastern Lobe vanadium body
  • a magnetically depleted NE-SW fault that bisects E58/532, which appears to be hydrothermally altered and a prime gold target
  • a discrete geochemical anomaly comprising of copper, nickel, chrome and vanadium located in the northwest of the tenement
