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. The exploration programme
will advance certain targets identified² in ASX Release (Feb 2023), namely drilling for extensions
to the Mt. Boppy Gold Mine and delineation drilling of a gold open pit at the polymetallic Pipeline
Ridge project.
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
.
The potential quantity and grade of the Exploration Targets are conceptual in nature
and, as such, there has been insufficient exploration drilling conducted to
estimate a Mineral Resource. At this stage it is uncertain if further exploration
drilling will result in the estimation of a Mineral Resource. The Exploration
Target has been prepared in accordance with the JORC Code (2012).

■ Exploration Target Basis
The Exploration Targets presented above are based on the following information and
assumptions:
Mt Boppy
• Targeted extensions of mineralisation at Mt Boppy are based on a combination
of geological information collected from previous mining and production,
Mineral Resource estimations and geological modelling of the deposit combined
with an internal geophysical review and structural analysis.
• The targeted mineral zones are anticipated to be similar in style to the Mt Boppy
orebody, being high silica low-sulphide mineralisation hosted within dominantly
left lateral shears and interconnecting thrusts
Pipeline Ridge
• The Pipeline Exploration Target ranging from 187-365kt grading at between 1.1-
1.5g/t Au (containing between 9 – 13 Koz Au); modelled to 70m below surface,
and based on 12,600m historic RC and Diamond drilling.
• The volume range (tonnages) of the Exploration Target is defined by Ordinary
kriging of the mineralised zone defined by the historic drilling completed via a
geological modelling software package.
• The assumed strike length of the Global Exploration Target is 1km while the
assumed strike length of the Stage 1 Exploration Target is 480m.
• The Exploration Target tonnage and grades were generated from mineralisation
contained between 0.6-0.8 g/t Au cutoffs.
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.

Figure 1: Location Mt Boppy and Pipeline Ridge among Manuka’s package of Cobar
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.

APPENDIX A – JORC 2012 TABLE 1
SECTION 1: SAMPLING TECHNIQUES AND DATA

Criteria JORC Code Explanation Commentary
Sampling techniques
• Nature and quality of sampling (e.g. cut
channels, random chips, or specific
specialised industry standard measurement
tools appropriate to the minerals under
investigation, such as down hole gamma
sondes, or handheld XRF instruments, etc.).
These examples should not be taken as
limiting the broad meaning of sampling.
• Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any measurement
tools or systems used.
• Aspects of the determination of
mineralisation that are Material to the
Public Report.
• In cases where ‘industry standard’ work has
been done this would be relatively simple
(e.g. ‘reverse circulation drilling was used to
obtain 1 m samples from which 3 kg was
pulverised to produce a 30 g charge for fire
assay’). In other cases more explanation may
be required, such as where there is coarse
gold that has inherent sampling problems.
Unusual commodities or mineralisation
types (e.g. submarine nodules) may
warrant disclosure of detailed
information.
• Diamond Drilling
• A portion of the data used for
exploration and evaluation of the Mt
Boppy and Pipeline Ridge projects has
been gathered from diamond core.
PQ,HQ and NQ core sizes have been
used historically at the Mt Boppy and
Pipeline Ridge prospects. This core is
geologically logged and subsequently
halved for sampling.
• Reverse Circulation (RC) Drilling
• Drill cuttings are extracted on a one
metre basis from the RC return via
cyclone. Representivity of sampling is
achieved from either
- passing material through a four-
tiered riffle splitter or else
- a 3-bag rotational sampler
• Approximately three kilograms of the
recovered material is bagged into calico
bags for analysis. Sample material is
submitted for gold analysis by either
500g Photon or 50g Fire assay. pXRF
measurements are taken every metre
drilled.
• Residual material may be retained on
the ground near the hole till evaluation
is complete. Composite samples may
be obtained from the residue material
for initial analysis, with the split
samples remaining with the individual
residual piles until required for re-split
analysis or eventual disposal.

Drilling techniques
• Drill type (e.g. core, reverse circulation,
open-hole hammer, rotary air blast, auger,
Bangka, sonic, etc.) and details (e.g. core
diameter, triple or standard tube, depth of
diamond tails, face-sampling bit or other type,
whether core is oriented and if so, by what
method, etc.).
• Method of recording and assessing core and
chip sample recoveries and results assessed.
• Measures taken to maximise sample
recovery and ensure representative nature
of the samples.
• Diamond Drilling
• Diamond drilling involves the coring of
rock by a rotating diamond bit, which
cuts through rock and emplaces the
core in a variable 1.5-commonly 3m –
6m core barrel located immediately
behind the bit. The core barrel is
retrieved at the discretion of the driller
(e.g. depending on ground conditions)
or when it is full. The core can be
marked to provide orientation data of
bedding or structures etc. Double
barrel and triple tube (in difficult
ground to protect washout of core)
core barrels are used for diamond
drilling.
• RC Drilling
• Down hole rock cuttings are generated
by a down-the-hole (DTH) rotating
hammer bit, which breaks and
pulverises the rock, which under high
air pressure is passed up the inner tube
and extracted from the RC return via
cyclone. Normally material is sampled
on a 1 metre basis (see above).
Drill sample recovery
• Whether a relationship exists between
sample recovery and grade and whether
sample bias may have occurred due to
• All geology input is logged and
validated by the relevant area
geologists, incorporated into this is

preferential loss/gain of fine/coarse
material.
assessment of sample recovery. No
defined relationship exists between
sample recovery and grade. Nor has
sample bias due to preferential loss or
gain of fine or coarse material been
noted.
Logging
• Whether core and chip samples have been
geologically and geotechnically logged to a
level of detail to support appropriate
Mineral Resource estimation, mining
studies and metallurgical studies.
• Whether logging is qualitative or
quantitative in nature. Core (or costean,
channel, etc.) photography.
• The total length and percentage of the
relevant intersections logged
• Manuka surface drill-holes are all
orientated and have been logged in
detail for geology, veining, alteration,
mineralisation and orientated
structure. Core has been logged in
enough detail to allow for the relevant
mineral resource estimation
techniques to be employed.
• Surface core is photographed both wet
and dry. All photos are stored on the
Company’s servers, with the
photographs from each hole contained
within separate folders.
• RC chips are geologically logged.
• Logging is quantitative in nature.
• All holes are logged completely.
Sub-sampling techniques
and sample preparation
• If core, whether cut or sawn and whether
quarter, half or all core taken.
• If non-core, whether riffled, tube sampled,
rotary split, etc. and whether sampled wet or
dry.
• For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
• Quality control procedures adopted for all sub-
sampling stages to maximise representivity of
samples.
• Measures taken to ensure that the sampling is
representative of the in-situ material collected,
including for instance results for field
duplicate/second-half sampling.
• Whether sample sizes are appropriate to
the grain size of the material being sampled.
• RC – Pulverised material is sampled from
either a 3 tier riffle splitter or 3 sample
rotating splitter (producing 3 - 5kg
sample). Samples are generally dry.
• Diamond Drilling - Half-core niche
samples, sub-set via geological features
as appropriate.
• Chips / core chips undergo total
preparation.
• Samples undergo fine pulverisation of the
entire sample by an LM5 type mill to
achieve a 75μ product prior to splitting.
• QA/QC is currently ensured during the
sub-sampling stages process via the use of
the systems of an independent NATA / ISO
accredited laboratory contractor.
• The sample size is considered appropriate
for the grain size of the material being
sampled.
• The un-sampled half of diamond core is
retained for check sampling if required.
For RC chips
• regular field duplicates are collected
and analysed for significant variance to
primary results.
Quality of assay data and
laboratory tests
• The nature, quality and appropriateness of
the assaying and laboratory procedures
used and whether the technique is
considered partial or total.
• For geophysical tools, spectrometers,
handheld XRF instruments, etc., the
parameters used in determining the analysis
including instrument make and model,
reading times, calibrations factors applied
and their derivation, etc.
• Nature of quality control procedures
adopted (e.g. standards, blanks, duplicates,
external laboratory checks) and whether
acceptable levels of accuracy (i.e. lack of
bias) and precision have been established.
• Recent drilling was analysed by a
combination of fire assay and ICP,
however this method will be modified
for the Mt Boppy / Pipeline Ridge
drilling programmes as outlined below;
• The current drill programme will be
analysed by pXRF, and sample prep and
gold analyses by Photon analysis at SGS
Orange.
• All gold diamond drilling samples
submitted for assay include at least one
blank and one Certified Reference
Material ("CRM") per batch, plus one
CRM or blank every 20 samples. In the
case of samples with observed visible
gold mineralization, a coarse blank is
inserted after the visible gold
mineralization to serve as both a coarse
flush to prevent contamination of
subsequent samples and a test for gold
smearing from one sample to the next
which may have resulted from
inadequate cleaning of the crusher and
pulveriser. The lab is also required to

undertake a minimum of 1 in 20 wet
screens on pulverised samples to
ensure a minimum 85% passing at -
75μm. No significant QA/QC issues
have arisen in recent drilling results.
• Photon Assay is to be introduced for
2025-26 exploration samples.
PhotonAssay™ technology (Chrysos
Corporation Limited) is a rapid, non-
destructive analysis of gold and other
elements in mineral samples. It is based
on the principle of gamma activation,
which uses high energy x-rays to excite
changes to the nuclear structure of
selected elements. The decay is then
measured to give a gold analysis. Each
sample is run through two cycles with a
radiation time of 15s. This methodology
is insensitive to material type and thus
does not require fluxing chemicals as in
the fire assay methodology. Highlights
of the PhotonAssay™ process are as
follows:
• The process is non-destructive; the
same sample accuracy can be
determined by repeat measurements of
the same sample. In addition, the
instrument runs a precision analysis for
each sample relating to the instrument
precision
• The process also allows for an increased
sample size, up to 500 g of crushed
product.
• The crushed material is not pulverised,
as in the fire assay process, and this
procedure ensures that gold is not
smeared or lost during pulverisation
(especially important if there is an
expectation of visible gold that is being
analysed)
• Historical drilling has used a
combination of Fire Assay, and Aqua
Regia / AAS analysis.
• These assay methodologies are
appropriate for the resources under
evaluation.
Verification of sampling
and assaying
• The verification of significant intersections
by either independent or alternative
company personnel.
• The use of twinned holes.
• Documentation of primary data, data
entry procedures, data verification, data
storage (physical and electronic) protocols.
• Discuss any adjustment to assay data.
• Currently no independent or alternative
verifications are available.
• There have been no twinned holes
drilled on the Mt Boppy and Pipeline
Ridge projects.
• Primary data will be collected utilising
LogChief. The information is imported into
a Datashed5 (SQL database server) and
verified.
• All data used in the calculation of
resources and reserves are compiled in
databases which are overseen and
validated by senior geologists.
• No adjustments have been made to any
assay data.
Location of data points
• Accuracy and quality of surveys used to
locate drill holes (collar and down-hole
surveys), trenches, mine workings and other
locations used in Mineral Resource
estimation.
• Specification of the grid system used.
• Quality and adequacy of topographic control.
• All data is spatially oriented by survey
controls via direct pickups by the
exploration team using either handheld
GPS or Differential GPS. Drillholes are all
surveyed downhole, deeper holes with a
Gyro tool if required, the majority with
single / multishot cameras.
• All drilling and resource estimation (if
applicable) is preferentially undertaken
in the UTM grid system at the various

sites.
• Topographic control is generated from a
combination of remote sensing
methods including Drone and LIDAR
surveys and ground-based surveys. This
methodology is adequate for the
resources in question.
Data spacing and
distribution
• Data spacing for reporting of Exploration Results.
• Whether the data spacing and distribution is
sufficient to establish the degree of
geological and grade continuity appropriate
for the Mineral Resource and Ore Reserve
estimation procedure(s) and classifications
applied.
• Whether sample compositing has been
applied.
• Data spacing is variable dependent upon
the individual orebody under
consideration. A lengthy history of
mining has shown that this approach is
appropriate for the Mineral Resource
Estimation process and to allow for
appropriate classification of the
resources.
• In the first instance no compositing is
undertaken. If applied it is carried out
based upon the modal sample length of
each individual domain.
Orientation of data in
relation to geological
structure
• Whether the orientation of sampling
achieves unbiased sampling of possible
structures and the extent to which this is
known, considering the deposit type.
• If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to have
introduced a sampling bias, this should be
assessed and reported if
• material.
• Drilling intersections are nominally
designed to be normal or close to
normal to the mineral zones as far as
geological controls allow.
• It is not considered that drilling
orientation has introduced an
appreciable sampling bias.
Sample security
• The measures taken to ensure sample
security.
• Manuka exploration samples are
assayed off-site, and samples are thus
delivered to a third-party transport
service, who in turn relay them to the
independent laboratory contractor.
Samples are stored securely until they
leave site.
Audits or reviews
• The results of any audits or reviews of
sampling techniques and data
• Audits and reviews on sampling
techniques have been undertaken on
previous resource estimations for the Mt
Boppy mine, with no significant flaws.

Mt Boppy
• The Mt. Boppy Gold Mine is located in
New South Wales approximately 50 km
east of Cobar at 435130 mE, 6508060
mN (MGA zone 55). Underground mining
from 1897 to 1923 extracted material to
a maximum depth of about 230 m. Open
pit mining by Polymetals and later Black
Oak Minerals occurred in two phases in
2002-2005 and 2015 down to a
maximum depth of 80 m. Mining
recommenced in mid-2020 under
Manuka Resources Ltd (MKR).
• Gold mineralisation occurs in quartz-
sulphide veining hosted in breccias and
tension fractures in two main north-
striking and steeply west dipping zones:
the thicker, more continuous East Lode
and narrower, less well developed West
Lode. Lodes are interpreted to be
truncated on their west side and at
depth by a NNE striking and steeply east-
dipping structure known as the West
Fault. During underground mining
workings were supported with timber
and back-filled with tailings sands from
processing. Sand fill samples grade
between 0.05 g/t Au and 38 g/t Au.
• Highest grades in remnant (un-mined)
material occur proximal to the
hangingwall zone of the East Lode above
dip flexures and near the intersection
with the West Lode.

Pipeline Ridge
• The Pipeline Ridge Au-Cu-Pb-Zn deposit
in the Cobar District of central New
South Wales is contained within the
Sarona Downes tuff member of the
Kopyje Shelf, 20 km southeast of the
town of Canbelego. The subregional
geological setting locates the deposit
adjacent to the Coonara Fault, which is
part of a north-northwest striking
terrane termed as the Canbelego-
Mineral Hill volcanic belt.
• The prospect is marked by extensive
hydrothermal alteration in the form of
sericitisation and chlorite alteration
emplaced on volcanics with an alkali-rich
(A-type) affinity. The deposit appears a
combination of an early Kuroko-style
VMS deposit associated with the initial
eruption of felsic volcanics in a marine
environment, with a later intermediate
sulphidation epithermal overprint ,
characterized by the strong
hydrothermal alteration with
chalcedonic, coliform and vuggy quartz

high grades) and cut-off grades are usually
Material and should be stated.
• Where aggregate intercepts incorporate
short lengths of high-grade results and
longer lengths of low-grade results, the
procedure used for such aggregation should
be stated and some typical examples of such
aggregations should be shown in detail.
• The assumptions used for any reporting of
metal equivalent values should be clearly
stated.

• These relationships are particularly
important in the reporting of Exploration
Results.
• If the geometry of the mineralisation with
respect to the drill hole angle is known, its
nature should be reported.
• If it is not known and only the down hole
lengths are reported, there should be a clear
statement to this effect (e.g., ‘down hole
length, true width not known’).
• Unless indicated to the contrary, all
results reported are downhole width.

Diagrams
• Appropriate maps and sections (with scales)
and tabulations of intercepts should be
included for any significant discovery being
reported. These should include, but not be
limited to a plan view of
• drill hole collar locations and appropriate
sectional views.
• Drilling at Mt Boppy Extensions and
Pipeline Ridge is still to be completed, and
appropriate diagrams will be provided in
future reports.
Balanced reporting
• Where comprehensive reporting of all
Exploration Results is not practicable,
representative reporting of both low and
high grades and/or widths should be
practiced to avoid misleading reporting of
Exploration Results.
• Appropriate balance in reporting of
exploration results reporting is to be
provided.

Other substantive
exploration data
• Other exploration data, if meaningful and
material, should be reported including
(but not limited to): geological
observations; geophysical survey results;
geochemical survey results; bulk samples –
size and method of treatment; metallurgical
test results; bulk density, groundwater,
geotechnical and rock characteristics;
• potential deleterious or contaminating
substances.
• There is no other substantive exploration
data associated with this release.
Further work
• The nature and scale of planned further work
(e.g. tests for lateral extensions or depth
extensions or large-scale step-out drilling).
• Diagrams clearly highlighting the areas of
possible extensions, including the main
geological interpretations and future drilling
areas, provided this information is not
commercially sensitive.
• Ongoing surface exploration activities
will be undertaken to support
continuing mining and exploration
activities at Mt Boppy and potentially
developing mining at the Pipeline Ridge
Project.
