Manuka accelerates gold exploration drilling programme

targeting near-pit extensions and new discoveries


Manuka Resources Limited (“Manuka” or the “Company”) confirms its Cobar Basin Gold

exploration program will commence first week December 2025.


Highlights

• Mt Boppy Gold Mine – targeting deep gold extensions and new discoveries.

o Historical production at Mt Boppy produced

1

~500,000oz Au grading ~15g/t Au.

o Identifying repeats of the high-grade mineralised Mt Boppy structure will be a

key objective of the drilling program.

o Previous drilling confirms Mt Boppy is open along strike and at depth.

o Initial three-hole drill program targeting depths of around 500m and testing

extensions of known Resource and a structural target similar to Mt Boppy some

1,000m to the south.

• Pipeline Ridge Gold Prospects – targeting shallow gold mineralisation.

o Located ~28km south of the Mt Boppy Gold Mine.

o Gold mineralisation, which expresses close to surface, has been previously

intersected by historic drilling.

o Extensive 3,165m shallow (up to 60m) drill program will target the previously

identified Pipeline Ridge Exploration Target

2

ranging between 187kt and 365kt

and grading between 1.1 g/t Au and 1.5 g/t Au.

• The Company remains focused on the restart of its existing Wonawinta Silver

Mine and Processing Plant within the next 6 months.

• Exploration results of the upcoming drilling program will represent the first

steps toward growing the current 10-year Cobar Basin production plan

3,4

.

Dennis Karp, Manuka’s Executive Chairman, commented:

“We are delighted to confirm the details of our upcoming exploration drilling program at the Mt

Boppy Gold Mine and Pipeline Ridge gold prospect. The historic tenor of gold mineralisation

mined at Mt Boppy and the shallow gold mineralisation known to exist at Pipeline Ridge make

this program highly prospective and extremely exciting.

Drilling is scheduled to commence in December 2025 with assays expected to be received and

reported during Q1 of 2026. We look forward to providing update on the program as it

progresses, and the potential to deliver impactful results for our shareholders.

Basin assets including the Wonawinta Silver Mine



Mt Boppy


The Mt Boppy deposit is silica dominated with associated veining and brecciation, indicating a

high-level hydrothermal system with multiple fluid phases. Planning of the upcoming exploration

program has integrated historic borehole geology and surface/airborne geophysics to refine

drilling targets.


What is evident is that complex thrusting and transpressional structures have emanated north

from the closure of the eastern Cobar basin rift shoulder. The coeval and adjacent Florida

volcanics (rhyo-dacite intrusives and subaerial felsic volcanic sequence) provide a potential

heat and fluid source for development of epigenetic gold deposits displaying some low-sulphur

epithermal characteristics.


Initial drilling at Mt Boppy will target the identification of gold mineralised zones and structures

(~200 to +500m below surface) that would underpin follow up phases of drilling and future

Resource upgrades (Figures 2).

Pipeline Ridge


The Pipeline Ridge prospect is a volcanic massive sulphide (“VMS”) style deposit located

approximately 28km south of Mt Boppy. The prospect historically has attracted a number of

phases of exploration drilling (totalling 6,590m DD; 6,079m RC and 4,832m RAB or Air Core).

Evaluation of the various drilling campaigns (some were for base metals and others gold) has

delineated a structurally controlled zone of gold mineralisation that requires validation.


Two zones of gold mineralisation (295m & 180m strike) locate within a larger ~1000m strike

length with intersections occurring down to over 150m depth (Figure 3). The Phase 1 drilling at

Pipeline Ridge is designed to delineate shallow (60m deep) free-milling gold oxide Resource for

potential open pit extraction, with Phase 2 drilling follow up deeper mineralisation.
