ASX Release
11th November 2025
SUBSTANTIAL AND ROBUST EXPLORATION TARGET DEFINED
FOR TRIUMPH GOLD PROJECT
Dart Mining NL (“Dart” or the “Company”) is pleased to announce the maiden Exploration Target for its
flagship Triumph Gold Project located 80km south of Gladstone, Central Queensland. The Triumph
Exploration Target is based on existing drilling where drill hole spacing is currently too sparse for
declaration of a JORC Mineral Resource. The Exploration Target therefore represents a strong growth
strategy for the Triumph Project through increased drilling density amongst proven drill hole
intercepts. The Company remains excited about gold prospectivity outside the Exploration Target.
HIGHLIGHTS
The Triumph Exploration Target includes:
• Declaration of the Triumph Exploration Target of 5.1 - 7.6 Mt @ 1.72 - 2.52 g/t Au for 285,100-
613,200oz gold, with a base case of 6.9Mt @ 2.29 g/t Au for 506,800oz gold;
• The Exploration Target declaration is an addition to the previously declared JORC Mineral
Resource of 2.16Mt @ 2.17g/t Au for 150,000oz gold at a 1g/t Au cut-off (ASX: DTM 4 Mar 2025);
• 90% of the Exploration Target lodes are defined within 500m of the existing Triumph Mineral
Resource;
• Triumph Exploration Target represents an ideal mixture of new deposits as well as near
prospect extensions, taking into account the existing drill hole database and Dart’s 2025
drilling results at New Constitution, South Constitution, and Big Hans;
• The Exploration Target is high quality as it is defined by drilling. Each of the 41 new lodes
identified has a minimum of 1 drill hole intercept and an average of 5. The spacing of this drill
hole data has previously been considered too sparse for Mineral Resource declaration and
hence presents an excellent growth pathway as an Exploration Target.
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).

Dart’s Chairman, James Chirnside, commented: “The development of the Exploration Target at
Triumph is a true representation of the value that Dart sees in the asset. The expansive amount of
drilling that was previously completed, whilst insufficient to include in a Mineral Resource, has paved
the way for the delineation of what is an impressive and robust Exploration Target. Dart will use this
to guide exploration strategy and to continue to improve and add to the Mineral Resource base at
Triumph.
Importantly, the Exploration Target only really focuses on open pit depths up to 200m. This is a
reflection of the depth of drilling historically, but as we have seen in the few deep holes drilled by
Dart, the potential for high grade underground targets is also present and included here but on a
more conservative basis.
While the ounces defined in the Exploration Target are impressive, the grade of the open pit targets
is equally as important. The Exploration Target presents a grade 2.29g/t Au compared to the current
Mineral Resource of 2.17 g/t Au. In the context of a strong and evolving gold market, Triumph can
be viewed as a key prospective Development Gold Project for Central Queensland.”
The Triumph Exploration Target builds on the March 2025 Inferred Mineral Resource of 2.16 Mt @
2.17g/t Au for 150,000oz gold which had already highlighted impressive growth since the maiden
Mineral Resource Estimate (ASX: DTM 4 Mar 2025). The Exploration Target, which is outlined in detail
in Table 1, shows a mix of Near Prospect extensions to existing resources at New Constitution, South
Constitution, Big Hans, Super Hans and Bald Hill as well as new Regional Targets. The Near Prospect
extensions are areas that were not classified in the previous Mineral Resource or new lodes that
Dart has drilled and intersected in its 2025 drilling programme. An isometric view of the Exploration
Target relative to the existing Mineral Resource is shown in Figure 1.
Approximately 80% of the Exploration Target ounces are classed as open pit targets (<200m deep)
with the remaining 20% as underground, this reflects the depth of existing drilling rather than
prospectivity. High-grade underground mining lodes remain a key target for resource expansion
which has been recently highlighted by Dart’s deep drilling along with additional shallow targets.

Regional Targets within the Exploration Target include:
• Advance gold mine with best drill intercepts of 3m @ 24.97g/t gold, 1m @ 45g/t gold and
3m @ 9.7g/t gold (ASX: DTM 2 Dec 2024). Advance was the deepest historical mine at 121m
depth and produced 2,605oz gold @ 77g/t between 1879 and 1881 from a 1.2-2.7m wide
quartz-calcite-altered granite formation (Lionel Ball, 1906, Report on the Norton Goldfield,
Queensland Geological Survey Publication No.208). At the bottom of the Advance mine,
121m depth, Ball (1906) reported a 1.5m wide calcareous formation grading 12.4g/t gold (8
dwt).
• Historic mines with low density drilling including Spotted Gum and Marodian with a best drill
intercept of 2m @ 8.92g/t gold (ASX: SHN 15 Jun 2023). The Marodian mine shaft is 98m deep
(Ball, 1906).
• Galena-Brigham Young, large strike length of workings with previous drill intercepts of 6m
@ 3.9g/t gold, 1m @ 20.4g/t gold, and 2m @ 8.9g/t gold (ASX: DTM 2 Dec 2024) and a large IP
chargeability anomaly at depth (ASX: MBK 31 Jan 2017).
Recent discoveries and bulk tonnage targets including at Handbrake Hill and Chief Adachi where
large IP resistivity lows occur, limited drilling includes intercepts of 3m @ 10.5g/t gold and 1m @
6.1g/t within 10m @ 1.2g/t gold (ASX: MBK 31 Jan 2017).
The Exploration Target is derived completely from the existing drill hole database and the known
mineralisation strike, depth, and orientation of surrounding deposits used to help guide the
interpretation. This makes the Exploration Target basis robust and sets out the impressive growth
strategy for Triumph. When considering the base case of the Exploration Target, in conjunction with
the existing Inferred Mineral Resource, Triumph has the potential to represent a deposit scale of
more than 659,000oz gold. A map highlighting the Near Prospect and Regional Exploration Target
lodes relative to the existing Inferred Mineral Resource is shown in Figure 1.
The mineralised domains that form the Exploration Target have been defined from existing drillhole
intersects which are located outside of the current 4 March 2025 Mineral Resource Estimation. The
Open Pit targets are identified as being <200m depth with a cutoff grade of 0.5 ppm Au.
Underground targets are >200m depth with a 2.5 ppm Au cutoff grade. Both the Near Prospect
4 | P a g e
extensions and the Regional targets use the same density from the existing Mineral Resource of
2.86 for ore material. The consistency of density between deposits, and the proximity of the
Exploration Target to the existing Mineral Resource is deemed suitable to share the same density
assumptions.
Exploration Targets were generated in geological modelling software (Leapfrog) by flagging
significant gold intersections outside of the resource estimate wireframes, or where the drill density
would not enable a resource estimate to occur. These intersections were then correlated with other
surrounding intersections to form a lode wireframe. A 2 pass nearest neighbour estimation was
used to populate a block model to report tonnes and grade for the Exploration Target. The new
lodes between Regional and Near Prospect interpretation is built from 216 drill hole intercepts of
gold not included in the Mineral Resource.
The breakdown of Exploration Target ounces between the known prospects and regional are
outlined in Table 2 and Table 3 for open pit and underground targets, respectively. Eighty percent
of the Exploration Target ounces are within the open pit range of less than 200m. This is a direct
reflection of the density of drilling across the project with majority of drill holes targeting shallow
mineralisation. With Dart’s deep drilling currently underway, Dart aims to understand the
underground potential for Triumph and if suitable, update the Exploration Target with additional
underground targets where possible. Having an extensive Exploration Target defined will allow Dart
to understand how best to move forward with drilling for the best conversion of drilling to Mineral
Resource possible (on a “drilled metres/ gold ounces” basis for example).
High- and low-level tonnes and grade ranges, in line with standard reporting of Exploration Targets,
are a factor from the base model as there is sufficient data to build a 3D model. The low-level
confidence factor of 0.75 (75%) and a high-level confidence factor of 1.1 (110%) was applied to the
base model. This confidence factor aims to provide a reasonable gauge for the likely outcome from
testing of the exploration targets. Capping was applied to several of the new lodes where excessively
high grades were skewing the overall estimation at the discretion of the Competent Person. National
Park and existing ML boundaries were used to limit the Exploration Target. All Exploration Target
tonnes exist on EPM 18486 and EPM 19343 only and none within the National Park.

An important consideration for the Exploration Target is how it will compliment the existing Mineral
Resource. The defined lodes are predominately within 500m of the existing Mineral Resource and
99% of the lodes within 1,000m of the existing Mineral Resource. The observed geological logging
highlights that the Exploration Target is the same mineralisation and alteration style as the existing
Mineral Resource when considering the Northern and Southern Corridor. In addition the grade
distribution comparitavely between the Mineral Resource and the Exploration Target are very
similar statistically. Figure 2 highlights that the grade distribtion of the Exploration Target is very
similar to the Mineral Resource.

intercepts.

PROPOSED EXPLORATION
To delineate and confirm the Triumph Exploration Target, Dart proposes a 30,000m drill hole
programme across these zones. This programme is in the stages of planning and Dart will look to
start to execute this programme in due course. The prioritisation of different lodes will be guided
by the initial drilling and expectations of anticipated $cost/ounce and total ounces to be converted
to Mineral Resource where possible. The current proposed programme is shown in Figure 3.

NEXT STEPS
At the Triumph Gold Project, Dart intends to:
• Drill test depth potential beneath the Southern Mineralised Corridor and chargeability
anomaly to the Northwest of New Constitution;
• Continue Diamond drilling to expand the existing resources along strike and at depth with
priorities defined on a cost/ounce and total ounces converted basis, possible mining
scenarios will also be considered;
• Undertake regional exploration, targeting the project area, as well as testing bulk tonnage
targets including those at depth; and
• Continue to review geochemical and geophysical databases to identify additional
prospective target zones for exploration in addition to existing resource and exploration
target areas

APPENDIX ONE
THE TRIUMPH GOLD PROJECT
The Triumph Gold Project (Triumph or Project) is located approximately 520km by road north of
Brisbane, Queensland, and is well serviced by the coastal port city of Gladstone 80km by road to the
north. The Project is comprised of two Exploration Permits: EPM 18486 and EPM 19343 covering an
area of 137.6 sq.km or 43 sub-blocks in total. The Company has recently applied for additional area
immediately adjacent east of the triumph project with EMP 29097.
Figure 6: Location of the Triumph Gold Project
Local Geology
The Triumph Gold Project is located in the Yarrol belt of the Wandilla Province (New England
Orogen), where late Permian to Middle Triassic leucocratic intrusives are scattered throughout
Devonian and Carboniferous sediments. Known mineralisation at Triumph is located within one of
these intrusive bodies, the Norton Tonalite.
The Norton Tonalite is dissected by numerous brittle faults and shears, as well as common minor
mafic intrusive dykes of dolerite to basaltic composition. There is a distinct magnetic low signature
at the core of the Norton Tonalite which is yet to be drill tested (ASX SHN: (ASX SHN: Robust Maiden
Resource at Triumph Gold Project (31 March 2022)).
10 | P a g e
Structure
The Norton Tonalite is sinistrally offset by 1.8km by the northwest-trending Norton Fault, which can
be traced for over 28km. Initially thought to post date mineralisation, a single drill hole has
intersected the interpreted Norton Fault which returned 1m @ 2.9g/t Au and 1m @ 2.2g/t Au (ASX
MKB: Triumph Gold Project Update Amended (25 July 2014) indicating that the fault may have been
active during the main gold mineralisation event.
On a local scale the Norton Tonalite has two distinct fracture orientations that both host gold
mineralisation. One fracture set is approximately east-west striking and the other is northwest-
southeast striking. These fracture orientations are likely to have formed contemporaneously (ASX
SHN: Robust Maiden Resource at Triumph Gold Project (31 March 2022)).
Mineralisation
Gold and silver mineralisation is hosted in quartz-sulphide veins with pyrite and arsenopyrite
forming the bulk of the sulphide. Calcite is abundant in some lodes and present in most or all of
them. Veins typically show sericite-chlorite alteration halos although this appears to be more
associated with quartz veining rather than sulphides. Mineralisation at Triumph is interpreted as an
intrusion related gold system (IRGS) (ASX SHN: Robust Maiden Resource at Triumph Gold Project
(31 March 2022)).
Morrison (Intrusion-Related Gold Deposits in North Queensland, GSQ Project final meeting 7th
December, 2017)
stated that there were over 130 known IRGS in Queensland with 17 of these having resources over
1 million ounces. Sunshine have stated that Triumph is analogous to the Ravenswood IRGS gold
deposit which has an endowment in excess of 5 million ounces of gold (ASX SHN: Follow Up Drilling
at Liontown (19 June 2024)).
Resource Highlights
The Project is located across the historic Norton Goldfield and has a current JORC (2012) Mineral
Resource Estimate prepared over five prospects in close proximity: Inferred gold resource of
150,091 oz made up of 2,16 million tonnes at a grade of 2.17g/t gold using a 1g/t cut-off has been
declared in 2025 (ASX: DTM Mar 2025).
More than 75% of the Triumph Inferred resource is within 100m of the surface and largely located
within 1.2km of strike within a 6km long structural corridor (ASX SHN: Follow Up Drilling at
Liontown (19 June 2024)). Dart considers that there is potential for proving up mineralisation below
current drilling and open pit depths that may result in underground mining options subject to
favourable economic studies.

APPENDIX TWO
JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
Criteria JORC Code explanation Commentary
Sampling
techniques
• Nature and quality of sampling (eg 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 (eg ‘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 (eg submarine nodules)
may warrant disclosure of detailed information.
• Sampling is a mixture of Diamond core (half and full), along with RC
chip sampling.
• Sampling for diamond core is at the geologist’s discretion, with
intervals typically ranging from 30cm to 1m.
• Sampling intervals for RC drilling are at a nominal 1m interval.
• Minimal RC composite samples are included. Composites are from 2
to 4m.
• Historic Sample prep information is unknown for inherited samples.
• Recent Samples are prepared with PREP-31B which includes crush to
70 % passing 2mm, riffle split off 1kg, pulverise split to better than
85% passing 75 microns.
Drilling
techniques
• Drill type (eg core, reverse circulation, open-hole hammer,
rotary air blast, auger, Bangka, sonic, etc) and details (eg
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).
• Drilling is a mixture of Reverse Circulation (RC) and Diamond Drilling
(DD).
• Recent 2025 Diamond Drilling is of NQ core size and is triple tube
drilling. Core is oriented where possible using the Reflex ACT III tool.

Drill sample
recovery
• 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.
• Sample recovery is unknown for historic drilling.
• Recent drilling – Core is measured after each run and core recovery
based on the drill metres is recorded.
12 | P a g e
Criteria JORC Code explanation Commentary
• Whether a relationship exists between sample recovery and
grade and whether sample bias may have occurred due to
preferential loss/gain of fine/coarse material.
• Once in the transition and fresh material, Triumph experiences
limited to no core loss with the exception of intensely broken zones
where recovery is still > 95%.
• No relationship has been observed between sample recovery and
gold grade.
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.
• All RC samples have been geologically logged.
• The drill core has been geologically and geotechnically logged to a
level to support appropriate mineral resource estimation, mining
studies and metallurgical studies. Core is logged both qualitatively
and quantitatively. Core tray photography is both wet and dry
photography.
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.
• Historic Diamond sample method has been recorded as half core.
• Historic RC sample method is unknown.
• Recent Diamond core is whole core sampling so no sub-sampling
techniques in the field are used which ensures appropriate in-situ
representation.
• Laboratory sample prep for historic samples is not recorded.
• Recent drilling has undergone PREP-31B method includes crush to 70
% passing 2mm, riffle split off 1kg, pulverise split to better than 85%
passing 75 microns. The larger 1kg riffle split is larger than the
standard 250g to reduce sample size bias.
• Sampling size is suitable to represent the mineralisation intersected.
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 (eg standards,
blanks, duplicates, external laboratory checks) and whether
acceptable levels of accuracy (ie lack of bias) and precision
have been established.
• QAQC status of historic samples is unknown.
• All recent samples have been analysed at ALS Global (ALS, Brisbane).
The below refers to recent QAQC techniques:
• All samples were assayed for Au using a 50g fire assay with AU-ICP22
determination as well as ME-MS61 for multi element. In the case
where key elements are over range, Ag, Pb, Zn, and Cu was
completed using OG-62. As completed with OG46, and Au completed
with GRA22.
• The three types of QAQC samples were used were Certified
Reference Material (CRM/Standards), Field Duplicates, and Blank
material.
• The Blanks consist of store-bought sand which has been shown to be
barren based on previous work. The Blanks are used to provide
13 | P a g e
Criteria JORC Code explanation Commentary
information of any possible contamination or calibration issues
during the crush, pulverisation, and analytical phases. The field
duplicates utilised the spear to collect a second sample to test
repeatability (precision) of the original sample. The standards
samples are used to test the accuracy of the analyses.
