Red Setter

Gold-Copper Mineralisation Confirmed Along 4km Diorite Trend

 

 9,000m Fully Funded Drill Programme Planned for 2026

 

 

Wishbone Gold Plc is pleased to provide an exploration update from its 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).

 

Results from the Company's 2025 drilling campaign confirm the presence of gold
and copper mineralisation within the Red Setter diorite trend, which extends
for approximately 4 kilometres. These assay results further support the
potential for the project to host a large-scale mineralised system within one
of Australia's most prospective gold-copper provinces.

 

For 2026 the Company has designed a 25 hole drilling programme of
approximately 9,000 metres to follow up on these encouraging results and to
test extensions of the mineralised system. The Company is well funded for the
2026 drill programme and is actively working with its geological teams to
mobilise the drilling crews to site as soon as practicable once the rainy
season ends in April.

 

Ed Mead, Wishbone Gold WA director, commented:

 

"The gold and copper assay results from the 2025 drilling programme are
consistent with previous results from Red Setter and highlight the potential
of the Red Setter system to host significant mineralisation along the
approximately 4-kilometre strike length of the diorite intrusion.

 

We appreciate that publishing these results has taken longer than expected
however, with a streamlined drilling approach and improved assay turnaround
times planned for the 2026 programme, we expect to generate more regular
exploration updates as we continue to advance the exciting Red Setter
Project."

 

Richard Poulden, Wishbone Gold's Chairman, commented:

 

"Red Setter continues to demonstrate the hallmarks of a significant
gold-copper system. With approximately 4 kilometres of prospective strike yet
to be systematically drilled, we believe the project has the potential to host
a substantial mineralised system.

 

The planned 9,000 metre drilling programme in 2026 will be the largest
undertaken at Red Setter to date and is designed to rapidly advance our
understanding of the scale and continuity of the mineralisation."

·      Mineralisation occurs within altered zones of the Red Setter
diorite intrusion and associated breccia zones, indicating a large mineralised
hydrothermal system.

·      Mobile Magnetotelluric (Mobile MT) geophysics has improved
understanding of the project's structural setting.

·      Focus has now returned to the main diorite trend where drilling
has consistently intersected gold and copper mineralisation.

·      25 hole drill programme (9,000m) planned for 2026 targeting
extensions to the mineralised trend.

 

Additional information from 2025 drilling programme

 

The 2025 drilling programme consisted of seven drillholes, including five
diamond drillholes targeting the main diorite trend and two drillholes testing
a Mobile MT geophysical target.

 

Drilling within the diorite intrusion successfully intersected multiple zones
of gold and copper mineralisation, confirming the presence of a significant
hydrothermal system within the intrusion and surrounding alteration halos.

 

Structural logging indicates that mineralisation occurs in multiple
orientations associated with sulphide-bearing vein systems, with alteration
intensity increasing with depth, accompanied by higher gold and copper grades.

 

The results confirm that the Red Setter diorite trend hosts widespread
mineralisation across a strike length of approximately 4 kilometres, which
remains largely untested by drilling.

 

2026 drilling programme details

 

A 25-hole drill programme totalling approximately 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

 

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