Balladonia Drilling Progress Report

BALLADONIA DRILLING UPDATE: PROSPECTIVE BROKEN HILL
TYPE GEOLOGY INTERSECTED WITH ASSAYS PENDING
•
•
7 diamond holes of the planned program now completed for 2,845m.
Prospective host rocks for BHT mineralisation intersected in each drill-hole.
AusQuest Limited (ASX: AQD) is pleased to advise that its maiden drilling program at the
Balladonia Base Metal Project in the Fraser Range region of Western Australia is
progressing well, with just over half of the planned drill-holes completed to date. The
Balladonia Project is subject to the Strategic Alliance Agreement (SAA) with a wholly-owned
subsidiary of South32 Limited.
The program, which was designed to test a series of Broken Hill Type (BHT) targets, is
expected to be completed in July subject to weather conditions, with final assay data
expected to be available within approximately six weeks of the completion of drilling.
Processing of drill core – including structural orientations, specific gravity and magnetic
susceptibility measurements – is taking longer than anticipated, resulting in some delays in
the delivery of core to the laboratory for analysis.
Figure 1: Detailed magnetic and gravity surveys showing the location of drill-holes.
Drilling to date has been completed at the Tea Tree, Tea Tree North and Half Way
prospects. These targets were defined by a combination of detailed gravity and magnetic
surveys which outlined strong anomalies indicative of prospective host stratigraphy and
possible base metal mineralisation similar to that found in the Cloncurry Region of NW
Queensland (host to the Cannington deposit) and the Broken Hill area of NSW (Figure 1).
At the Tea Tree prospects, drilling along strike from the initial drilled section (see ASX
release, 30 June 2022) intersected further banded iron formations (BIF’s) and garnetiferous
quartzites, extending the prospective package of rocks from Tea Tree to Tea Tree North – a
distance of at least 5km – and inferring extensions to the south, where magnetic data
suggests that prospective stratigraphy could extend for up to 20km. Assay results are
awaited.
Drilling at the Half Way prospects also intersected significant amounts of BIF stratigraphy but
without the garnetiferous quartzites that are present at Tea Tree. The BIFs occur with mafic
amphibolites and garnet gneisses with evidence of silica alteration within the sequence,
suggesting strong prospectivity for base metals outside of the Tea Tree trend. Assay results
are awaited.
AusQuest’s Managing Director, Graeme Drew, said: “Initial indications from the drilling
completed to date support the presence of prospective host rocks at Balladonia and provide
further encouragement for our ongoing exploration campaign targeting base metal
mineralisation in the area.
“We look forward to receiving assay data from the holes completed to date and those still to
be drilled, which provide us with further insights into the geological comparisons being made
with productive base metal regions in NW Queensland and Broken Hill,” he added.

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.
• 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).
• Drill core is sampled at 1 metre intervals. Four metre composite
samples are collected from the RC pre-collar samples.
• Where HQ and NQ2 core was sampled, core was cut in half with
half sent for analysis and half retained for geological and quality
control purposes.
• Sample intervals were measured by tape from depth intervals
shown on core blocks labeled by the drillers, as per standard
industry practice.
• 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
• Core recovery was determined by comparing core lengths measured
against drilled intervals shown on core blocks and recorded on the
logs.
• Experienced diamond drillers were engaged to ensure maximum
core recovery.

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.
• Core samples were collected by cutting core in half along its length
and sampling over 1 metre intervals.
• Reverse Circulation pre-collar samples were collected by collecting
a scoop of sample from individual 1 metre samples and
compositing them over 4 metre intervals.
• The sample sizes are appropriate for the geological materials being
sampled.
Quality of assay
data and
laboratory tests
2
• Assaying of the drill samples is by standard industry practice.
• The samples are sorted and dried. The whole sample is crushed
then split by riffle splitter to obtain a representative sub-sample
which is then pulverized in a vibrating pulveriser.
• A portion of the pulverized sample is then digested and refluxed
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.

Drill hole
Information
• A summary of all information material to the understanding of the exploration results
including a tabulation of the following information for all Material drill holes:
o easting and northing of the drill hole collar
o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole
collar
o dip and azimuth of the hole
o down hole length and interception depth
o hole length.
• If the exclusion of this information is justified on the basis that the information is not
Material and this exclusion does not detract from the understanding of the report, the
Competent Person should clearly explain why this is the case.
• 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.
• 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 relevant drill hole data are tabulated below and
provided in the ASX release.
• 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.
• 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.
• 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.
• The nature and scale of planned further work (eg tests for lateral extensions or depth
extensions or large-scale step-out drilling).
• Diagrams clearly highlighting the areas of possible extensions, including the main
