• High priority targets selected from the current inventory of 24 are being tested as part of Western Yilgarn’s ongoing Phase 4 auger drilling at Ida Holmes Junction
  • Exploration underway at new tenements of farm-in deal with Fleet Street Holdings
  • Pending assay results aim to delineate AC/RC drill targets


Special Report: Interim assay results are pending from the Phase 4 auger geochemistry drilling campaign underway across several of 24 prospective targets at Western Yilgarn’s Ida Holmes Junction project in WA.

Highly prospective for copper, nickel, platinum group elements, and LCT pegmatites Ida Holmes Junction is ~50km southwest of Gold Fields’ Agnew Gold project and centred on the intersection of the Holmes Dyke and the Mt Ida Fault.

It’s comprised of six granted contiguous exploration licences covering a combined ~477km2 and Western Yilgarn (ASX:WYX) has the option to farm-in to an additional 207km2 after reaching an agreement with Fleet Street Holdings projects covering the Holmes Dyke.

The tenements cover the intersection of Holmes Dyke and the regional Ida Fault, which is interpreted to be a fundamental, early steep structure effectively marking the boundary between the Eastern Goldfields Super Terrane in the east and the Youanmi Terrane to the west.

Ida Holmes Junction also enjoys nearology to the Leinster and Mt Keith operations – two world-class nickel projects operated by BHP (ASX:BHP), along with several +2Moz gold operations including the Agnew, Lawlers and Bellevue mining operations.

It’s also 60km from Delta Lithium’s (ASX:DLI) 12.7Mt @ 1.2% Li2O Mt Ida lithium project and 90km south of Liontown Resources’ (ASX:LTI) 156Mt @ 1.4% Li2O Kathleen Valley.


Phase 4 kicks off

Assay results from early holes are pending  from Phase 4 auger drilling campaign testing several of 24 high-priority copper-nickel-PGE and LCT pegmatite targets discovered during the first three phases of the program.

646 auger drill holes have been completed so far in the southeast section of the recently granted E36/1066 lease with samples now in Perth for pXRF assay.

An auger geochemistry team has now relocated to the far western end of the project to complete planned sampling relating to a potential copper target identified through previous rock and soil samples.

With activities now underway on Fleet Street Holdings’ most westerly lease “Hells Gate” (E57/1235) as well, the team has relocated to a base at Sandstone.

WYX general manager Gavin Rutherford says he’s extremely keen to see the assay results from this interim round of samples in the partially completed campaign.

“The identified copper-nickel-PGE and LCT pegmatite prospectivity in the lease to the immediate north continues right up to and along the boundary of the recently granted lease,” Rutherford says.

“The Phase 4 auger geochemistry program is well progressed and we are awaiting pXRF results.”
