 Red Setter Exploration Update

Drilling update and New Access Road Application

Wishbone Gold Plc is pleased to provide this update to shareholders on activities at the Company's Red Setter Gold Dome Project, located 20km south-west of Greatland Gold Plc's (AIM and ASX: GGP) Telfer gold mine, and 50km east of the Nifty Copper Mine owned by Cyprium Metals Limited (ASX: CYM) in Western Australia (Figure 1).

Highlights

· New ~30km access road between Nifty Copper Mine and Red Setter applied for.

· Heritage survey of access road booked for early April.

· Seven Reverse Circulation holes for a total of 1,509 metres completed.

· Six Diamond Drill holes for a total of 3,298.7 metres completed.

· Last Diamond Drill hole for 300 metres depth underway.

· Three diamond drill holes have now been processed with assay results pending.

An application for a new access road between the Nifty Copper Mine and the Red Setter Project has been applied for, with miscellaneous licence L45/872 now in process for grant early next year. A heritage survey of the new road has also been booked for the first week of April 2026. This new road once completed, is over flat ground between sand dunes and logistically far easier to navigate with heavy trucks. The new road will allow additional services for Wishbone, and better access to Nifty provides the potential availability of accommodation, fuel, water and the use of the Nifty all weather airport and scheduled flights for worker roster changes. This will change the way the Company has been operating and allow a far simpler exploration drilling program in 2026. Nifty is only 50km from Red Setter and will act as the new exploration camp providing considerable cost savings for a bigger 2026 drill program.

In addition, a new Mobile MT survey has been flown over the north-west extension to Red Setter, with results currently being processed by Expert Geophysics Limited. The survey also covered two smaller Wishbone tenements south of Telfer.

To date, the 2025 Wishbone drilling campaign includes seven Reverse Circulation ("RC") holes for a total of 1,509 metres and six Diamond Drill ("DD") holes for a total of 3,298.7 metres. Five of the seven RC holes, totalling 1,109 metres, were either diamond pre-collars or targeted shallow extensions of known gold and copper mineralisation. The remaining two RC holes were for water bores, for a total of 400 metres, with one of the water bores successfully intersecting the water table securing a reliable water source for the project. All 1,509 metres of RC samples will be submitted for fire assay and multi-element assay.

The final 300-metre-deep drill hole by the DD rig is underway before a break for Christmas. Two of the six diamond holes tested a MMT target with the other four diamond holes targeted extensions of known gold and copper mineralisation. It is estimated that 2,178 metres of core drilled to date will be submitted for fire assay and multi-element assay with sample lengths of ~1m, once all drill holes are processed. Three drill holes have been cut and sampled with assays pending, and a fourth hole to start cutting shortly.

Assay results will be released over the next few months, and the plan for 2026 will be announced when all results are collated. The Red Setter Dome breccia and surround Diorite remain key targets, based on assay results to date.

Ed Mead, Wishbone Gold WA director, commented: "This year has provided many challenges in completing RC and Diamond drill holes to date, and this new access road will make a tangible improvement to our ability to execute our drill program in an efficient manner. Currently we have to source and provide for everything on a remote site basis from Perth, Port Hedland or Marble Bar which is inefficient. A new road to Nifty will significantly simplify access to Red Setter and speed up getting drill core processed and assayed for 2026 drilling programs. We will have assay results from 1,509 RC samples and an estimated 2,178 assays from DD samples to report over the next few months, with the final 300 metre drillhole for the 2025 drilling season now underway. The plan is to receive all assay results and then restart drilling on site when the summer wet season is over. We are extremely happy with what we have seen in drill core to date and need the assays to quantify our enthusiasm for the Red Setter Project. We look forward to increased news flow of drilling results over the next few months as results come in."
