INCREASING COPPER GRADES AND WIDTHS CONTINUES TO
GROW THE SCALE OF CANGALLO
Highlights
• Wide spaced Reverse Circulation (RC) drilling continues to define a continuous
mineralised corridor exceeding 1500m in length with broad intercepts of copper-gold
mineralisation confirming the large-scale nature of the porphyry system.
• Significant intersections from the first 9 of 13 drill-holes include:
o 269m @ 0.29% Cu and 0.05 g/t Au from 160m (CANRC045) (EOH) including:
38m @ 0.34% Cu and 0.03 g/t Au from 178m
32m @ 0.44% Cu and 0.07 g/t Au from 274m
46m @ 0.38% Cu and 0.06 g/t Au from 346m
o 214m @ 0.28% Cu and 0.11 g/t Au from 124m (CANRC044) including:
30m @ 0.42% Cu and 0.18 g/t Au from 220m
26m @ 0.37% Cu and 0.06 g/t Au from 260m
o 184m @ 0.25% Cu and 0.05 g/t Au from 208m (CANRC046) including:
30m @ 0.44% Cu and 0.10 g/t Au from 328m
o 92m @ 0.32% Cu and 0.03 g/t Au from 102m (CANRC048)
• Higher copper and gold grades within mineralised dykes and stockwork veins are
prevalent in the south, with multiple +0.5% Cu intervals highlighting strong potential for at
least one porphyry centre to be located in this area. Significant results include:
o 12m @ 1.09% Cu and 0.01 g/t Au from 112m (CANRC048)
o 12m @ 0.77% Cu and 0.08 g/t Au from 102m (CANRC047)
o 6m @ 0.87% Cu and 0.17 g/t Au from 4m (CANRC045)
o 10m @ 0.61% Cu and 0.09 g/t Au from 276m (CANRC045)
o 6m @ 0.67% Cu and 0.09 g/t Au from 378m (CANRC045)
o 14m @ 0.56% Cu and 0.15 g/t Au from 332m (CANRC046)
o 12m @ 0.50% Cu and 0.43 g/t Au from 138m (CANRC044)
• The potential of the Cangallo copper discovery continues to grow with extensive near-
surface copper oxide mineralisation and strong indications of higher grade hypogene
mineralisation in a strategic location close to the coast and key infrastructure.
• Assay results from 4 of the 13 RC drill-holes are outstanding with +5,000m diamond drill
program planned for late May to target higher‑grade copper sulphide extensions at depth.
• Permitting of the Stage 4 drill pads has been prioritised to enable further drilling in the
highly prospective southern portion of the prospect as soon as possible.

AusQuest Limited (“AusQuest” or the “Company”) (ASX: AQD) is pleased to report the
successful completion of the Stage 3 RC drilling program at its 100%-owned Cangallo
Porphyry Copper-Gold Project in Peru, with results continuing to demonstrate both the scale
and emerging grade potential. A full assessment of the newly received geochemical data is in
progress.
The current round of the Stage 3 RC drilling program was designed to confirm the continuity
of the mineralisation intersected in Stages 1 and 2 and to further evaluate the scale potential
of the Cangallo porphyry copper-gold system. Results to date continue to support the
interpretation that Cangallo is a very large and laterally continuous porphyry system,
extending over more than 1,500 metres in length (see Figure 1 for plan-view and Figure 2 for
long section).
Figure 1: Cangallo Prospect showing location of Stage 3 RC drill-holes with copper profiles and potential
extensions inferred by drilling and surface copper and gold anomalism (Surface rock-chip assays first
reported in ASX releases - 30 March and 09 November 2023).

Figure 2: Long Section A-A’ showing the open-ended extent of copper mineralisation defined to date by
the RC drilling program.
To date, assay results from 9 of the 13 drill-holes (from the southern sections) have been
received, highlighting both broad copper intersections within the stockwork veined volcanic
host rocks, and higher copper grades (>0.5% Cu) within mineralised intrusive dykes which
appear to be more prevalent in the south.
In particular, intercepts of 12 metres grading 1.09% Cu (CANRC048) and 12 metres grading
0.77% Cu (CANRC047) occur within porphyritic quartz diorite dykes, highlighting the
potential of the system to produce higher copper grades within the source (parent) porphyry
stock. The true thickness and orientation of these dykes is not known at this stage given the
broad-spacing and nature of the drilling (RC) completed to date.
Further +0.5% Cu intervals greater than 10 metres in thickness have been reported within the
current assay results. These include:
Hole ID From (m) To (m) Interval (m) Cu %
CANRC044 138 150 12 0.50
CANRC044 222 232 10 0.51
CANRC045 276 286 10 0.61
CANRC046 332 346 14 0.56
CANRC047 102 114 12 0.77
CANRC048 112 124 12 1.09
These intersections occur within the broader mineralised envelope (>0.1% Cu), demonstrating
the capability of the system to produce higher-grade copper either through supergene
enrichment processes or as hypogene mineralisation within dykes and stockwork veins
occurring with the porphyry system.
4
Gold values associated with the copper intersections also appear to be increasing to the south
particularly in drill-hole CANRC044, the south-easternmost drill-hole, which contains several
intercepts (>10m) reporting average gold grades ranging from 0.15g/t Au to 0.43g/t Au (see
Table 1). This gold trend is supported by earlier surface sampling results which suggest
increased potential for gold in the southern area.
Most of the higher-grade intercepts occur within the oxide zone and are associated with copper
oxides (malachite, chrysocolla, atacamite) and/or secondary copper sulphides (chalcocite,
bornite and rare covellite) that occur within the top ~300 metres of section and may be
recoverable using heap leaching techniques.
Next Steps
A full assessment of the multi-element geochemistry and geology from the RC drilling program is
in progress to identify areas within this large-scale system where higher-grade hypogene copper
mineralisation is more likely to occur. Vectors from this work will be used to guide deeper diamond
drilling to test targets identified by this process.
Diamond drilling (+5,000m) is scheduled to commence in late May to help locate higher‑grade
depth extensions of the copper sulphide mineralisation. Priority sites for the diamond drill-holes
will be finalised once all RC assay data has been received and assessed.
Permitting for the Stage 4 drill pads has been prioritised to facilitate further drilling in the south of
the prospect as soon as possible, following the encouraging drilling results reported from the
southern drill-section. It is anticipated that the permits should be available in Q3 CY2026 to allow
Stage 4 drilling to commence shortly thereafter.
Commenting on the latest results, AusQuest’s Managing Director, Graeme Drew, said:
“These results continue to reinforce Cangallo as a large and growing porphyry copper system,
with mineralisation now defined over more than 1.5 kilometres of strike and remaining open in
multiple directions.
Importantly, we are now seeing higher-grade copper emerging within the system, including
results exceeding 1% Cu – which supports our view that we are vectoring towards a higher-
grade core. The potential for higher copper grades is an exciting development for the project
given the broad spaced nature of our current drilling.
We are encouraged to see that copper continues to occur from surface and is oxidised to
depths of 200 to 250m, making it a viable proposition for an early open-cut operation, with the
shallow copper potentially recoverable by heap leaching – a low-cost processing option.
“Deeper hypogene sulphide mineralisation that is associated with multi-phase vein systems
containing chalcopyrite and bornite, and potential porphyry stock systems, will be targeted by
the upcoming diamond drilling once the RC drilling results have been fully assessed.
“We look forward to receiving assay results for the remaining drill-holes which should add
further to the Cangallo story, and keeping shareholders updated on results as they become
available.”
Peru: Scale and Grade / Early comparisons
Peru is one of the largest copper producers in the world behind Chile, with around 2.8Mt of
copper being mined and processed per annum. The bulk of this production comes from large
porphyry copper projects that are located along the Andean Belt that extends from Chile in the
south to Ecuador in the north.
5
Porphyry deposits are typically large (often over 1 billion tonnes of ore) and usually open-
cuttable with low waste to ore ratios. The shallower parts of these ore bodies are usually oxide
ores that can be processed using heap leach methods, resulting in lower development and
operational costs and positive short-term cash flow.
Copper grades for the oxidised ores are generally lower (except where there is a supergene
enriched zone) than the deeper hypogene ores which require more expensive mining and
processing methods.
There are a number of profitable large-scale porphyry copper operations within the Arequipa
District where Cangallo is located as well as potential developments at Zafranal and Tia Maria,
using head grades between 0.20% and 0.40% Cu. These mines have multi-decade mine-lives
and are long-lived assets.
The economic viability of the Peruvian resources is often affected by a range of issues
including location, altitude, proximity to infrastructure and water, as well as land usage conflicts
with local communities. In this regard Cangallo is well placed.
The Cangallo Project is particularly well located with respect to the above, being close to
significant infrastructure, 25km east of the town of Chala and at low altitudes within 10km of
the coast. Community consultation has formed part of the Company’s exploration process, with
no critical issues identified to date.
Peru is a stable country and the government is supportive of new mine developments as they
add significantly to the Peruvian economy and the communities where they are located.

in Peru
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.
• Samples are collected using a tube sampler by spearing
into each one metre sample bag and compositing samples
on a two-metre basis.
• Sample depths are determined by the length of the rod-
string and confirmed by counting the number of samples
and bags at the drill platform as per standard industry
practice.
• A ~4kg sample is collected for representivity.
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).
• RC Drilling with a face sampling bit has been used with a
hole diameter of approximately 132mm.
• Down-hole surveys are recorded at 10m intervals using a
down-hole gyroscope probe.
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.
• 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.
• Experienced RC drillers and an appropriate rig were used
to provide maximum sample recovery.
• Minimal to no water was encountered in all drill holes.
• The weight of every bulk 1 metre sample was recorded
and checked for sample recovery estimates. Sample
recovery was acceptable to industry standard.
• The sample weight of every laboratory sample was also
collected and weighed on site for future reference.
• At this early stage of exploration, it is not known if there
is a relationship between sample recovery and assay
grade.

experienced geologists to identify key rock types and
mineralization styles.
• Sample logging was qualitative with visual estimates of
mineralization made for later comparison with assay
results.
• All one metre drill samples were logged.

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 samples were collected every 1 metre into large
plastic bags and stored in rows per depth at the drill site.
• Samples were collected using a 50mm tube sampler and
composited on a two metre basis.
• Certified coarse blanks and fine standards are inserted
approximately every 35 samples and duplicates taken
every 20 samples for quality control purposes.
• The sample sizes are considered appropriate for the
geological materials sampled.
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

• 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.
• Assaying of the drill samples is by standard industry
practice.
• The samples are sorted, dried, crushed then split to obtain
a representative sub-sample which is then pulverized.
• A portion of the pulverized sample is digested using a
four acid digest (Hydrofluoric, Nitric, Hydrochloric and
Perchloric) which approximates a total digest for most
elements. Some refractory minerals are not completely
dissolved.

• All relevant drill hole data and information are provided
below.
Data aggregation
methods
• In reporting Exploration Results, weighting averaging techniques, maximum and/or
minimum grade truncations (eg cutting of 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.
• Aggregate assay intervals quoted for the RC drill-holes
in this report are based on copper assays, using a cut-off
value of ~0.1% Cu, and maximum internal waste of 6
metres.
• For higher grade intervals (quoted as including) a 0.3%
Cu cut-off and a 6m internal waste limit were used.
Relationship
between
mineralisation
widths and
intercept lengths
• 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 (eg ‘down hole length, true width not known’).
• All intervals reported will be down-hole lengths. True
widths will be unknown at this stage.
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.
• All drill holes are shown on appropriate plans and
included in the ASX release.
• Relevant drill-hole cross sections will be provided when
all assays have been received and assessed..
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.
• At this early stage of drilling, only significant assay
results have been reported.
Other substantive
exploration data
• Other exploration data, if meaningful and material, should be reported including (but
not limited to): geological observations; geophysical survey result
