Significant Breccia Pipe Intersected at Red Setter Gold Project in Western Australia

Over 130 metres of Breccia with Sulphides Intersected from 570 metres

Wishbone Gold Plc is pleased to announce that drilling at the Company's Red Setter Gold Dome Project, located 15km South West of Greatland Gold Plc's (AIM and ASX: GGP) Telfer gold mine in Western Australia (Figure 1), has drilled into the top of a significant breccia pipe with its first hole of this drill program (Figures 2-8). Zones of quartz-carbonate veining and sulphides of chalcopyrite and pyrite were observed from 520m, with increasing intensity towards ~570m. Variable intensity of brecciation has been observed over an interval of more than 130m from ~570m, to current depth of ~700m with drilling still continuing as of this release.

The drill plan for this hole (hole number 25RSDD001) is to now continue down to total depth of ~750m, and then potentially drill deeper later on in this program, when additional drill pipe is mobilised to site by the drilling contractor.

Transport of the core to Perth to be cut and assayed will now be expedited.

As announced on 25 April 2025 the Mobile MT domal target interpreted by Expert Geophysics Limited (EGL), showed the original top of target depth at around 550m.

On completion of the current drill hole, a step out hole will be collared from surface to the south-west of the current hole aimed at assessing the lateral extent of this breccia zone. The step out drill hole will be targeting around 50m to 75m distance from the current down hole position at a depth of 550m.

Ed Mead, Wishbone Gold WA director, commented: "It is outstanding to see the emergence of this mineralised breccia pipe and see the intensity of brecciation and the amount of quartz-carbonate veining and sulphides. This is a fantastic outcome as brecciation typifies a style of gold and copper mineralisation seen at both the nearby Telfer and Havieron deposits. Transportation of the core to Perth to be cut and assayed is a priority. We look forward to updating shareholders as we further test this exciting target."
