Shallow and Wide Gold Intersected at Red Setter

Wishbone Gold Plc is pleased to announce that highly positive gold assays have been returned from the first of the assay results received from its shallow Reverse Circulation ("RC") drilling at its Red Setter gold-copper project. 

Red Setter is 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).

Highlights

·      These newly discovered shallow gold zones at Red Setter are a major vindication of our strategy and provide a material enhancement to the prospects and outlook of the project

·      The RC holes are pre-collars for the deeper diamond drilling which is underway at the site

·      The shallowest gold mineralisation intercept at Red Setter to date starts at 45m in drill hole 26RSRD003

·      Drill hole 26RSRD003 ended in mineralisation with [email protected]/t Au from 139m, including [email protected] g/t Au to end of hole at 150m, highlighting gold mineralisation is open at depth here

·      The diamond drill rig is now over 26RSRD003 and extending the drill hole, which is the most southern drill hole Wishbone has drilled to date

·      All areas in the drill programme have been heritage cleared and all Programme of Work ("PoW") documentation from the Department of Mines, Petroleum and Exploration are in place.

·      A High Definition Transient Electromagnetic ("HDTEM") survey quote has been requested to cover Red Setter and other promising targets on ballot won tenement E45/7169 covering an area located 25km north-west of Telfer. HDTEM surveys offer unparalleled depth penetration, high-resolution subsurface mapping, and the ability to detect conductive ore bodies through thick, challenging overburden. This non-invasive method greatly reduces exploratory drilling costs by accurately pinpointing high-probability drill targets.

Ed Mead, Wishbone Gold WA director, commented:

"The gold assay results from the first seven RC drill holes are terrific and a real game changer for Red Setter and the Company. To find gold starting as shallow as 45m is amazing and to see the hole grading [email protected]/t gold that was still in mineralisation is incredible. In the first three months of this year, Telfer processed 4.82Mt at 0.59g/t Au and 0.1% Cu, so we are above the head grade for gold mineralisation. The diamond drill rig on site is now extending the hole. This hole indicates the gold system is open to the south-east, where all heritage clearances are complete and an additional 3km of potential strike has been added on top of the 4km diorite target."

"The current 2026 drill programme is going to plan and with faster turnaround times on assay results, we expect to generate more regular exploration updates for shareholders as we continue to advance the exciting Red Setter Project. We are adapting the drill programme to results and further RC holes have already been added to immediately follow up the shallow gold discoveries."

2026 drilling programme details

The 2026 drill programme at Red Setter is well underway. 14 RC holes as pre-collars for the diamond drilling have now been completed, and gold assays have been returned for the first 7 RC holes (see table 1 for significant gold intercepts). Copper assays have not yet been reported.

Further RC drill holes will commence when Core Drilling's RC rig returns to site in mid-July.

Wishbone initially designed a 25 hole RC and diamond drilling programme of approximately 9,000 metres to follow up on the encouraging 2025 assay results and to test extensions of the mineralised system. Following the shallow gold discovery the programme will now be extended and modified to target this gold. The 25-hole drill programme 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

Drilling will utilise reverse circulation pre-collars followed by diamond core tails, targeting depths of around 400 metres.
