Red Setter Gold-Copper Project Update

Further to the announcement on 20^th April, Wishbone Gold Plc is pleased to provide an update on the exploration activity at the Company's Red Setter Project in the Paterson Province of Western Australia, located 20km south-west of Greatland Gold Plc's (AIM and ASX: GGP) Telfer gold mine, and 50km east of Cyprium Metals Ltd's (ASX: CYM) Nifty copper mine (Figure 1).

The first phase of the 2026 drilling contract started on 5^th May with the reverse circulation ("RC") rig. The initial focus is to drill approximately 25 holes for ~3,500m with the RC rig, of which 14 holes for 2,182 metres has been completed. The second phase of the contract covering a further 4,500m of diamond drilling started on 27^th May, and two holes for 687 metres has been drilled and the drill programme as a whole is targeting depths from surface of up to depths of 600 metres along an identified gold-copper system.

Activities to date on site have progressed as initially planned and samples are being sent to Perth for assay testing on an ongoing basis, with initial results expected before the end of July.

In order to get the drill programme operational, the crew from Apex Geoscience Consultants and Core Drilling, who manage the day-to-day exploration and drilling across the Company's Western Australian assets have had to create multiple drill pads, drill water bore holes, establish a camp and mobilise the track mounted drill rigs and their ancillary equipment on site.

The 25-hole drill programme totalling up to 9,000 metres has been designed to:

·      Test extensions of known gold-copper mineralisation

·      Evaluate continuity along the 4km diorite trend

·      Improve understanding of structural controls on mineralisation

·      Target zones of strongest alteration and sulphide mineralisation

In addition, the final report following the heritage survey on the proposed new access road from the Nifty mine and airport to Red Setter has been completed and the Company expects to be granted permission to progress the road's construction on the grant of the required Miscellaneous Licence. The heritage report has also given approval to relocate the support camp and accommodation to Red Setter which will occur once Wishbone has approvals to create the new access road.

Richard Poulden, Wishbone Gold's Chairman, commented:

"Activity on the ground at Red Setter over the last month has been as expected, with the team making excellent progress with the initially RC drilling program and now the diamond drilling. We are on track to complete the 9,000m of drilling in this first phase of the 2026 programme.  The results from the overall drill programme will establish the pattern of mineralisation at the project and guide our team for the next phase of drilling for the later parts of 2026."
