Successful completion of maiden RC drill program at Lyons River Project in Western Australia


Highlights

  • Eight RC holes completed totalling 1,989 metres testing lead-zinc BHT/SEDEX and copper targets.

  • Multi-element analytical results from the RC drilling program expected during the March quarter 2022.

Dalaroo Metals Ltd ( ASX: DAL or “Company”) is pleased to provide an update on exploration activities at Lyons River Project in Western Australia where its program of RC drilling has been successfully completed at the Four Corners prospect (Figure 1 and 2). Lyons River comprises a strategic (100% owned) land position of 703 km[2] within the Proterozoic Mutherbukin Zone of the Gascoyne Province. The Company believes the district is an emerging Broken Hill Type (“BHT”) / Sedimentary Exhalative (“SEDEX”) deposit setting.

A total of eight RC drill holes for 1,989 metres holes ranging in depth from 219 to 287 metres have been completed (Figure 1). The RC drill program at the Four Corners prospect was designed to test several base metal targets and obtain greater understanding of the metamorphosed stratabound sequence of pyritic psammitic and pelitic rocks and corresponding anomalous Pb-Zn geochemistry.

Multi-element assay results for 4m composite samples are expected to available in the March quarter 2022.

The Four Corners prospect is one of six regional Pb-Zn soil geochemical prospects identified at Lyons River within a Proterozoic basin setting covering an area of 30 km by 10 km (Figure 2).

Next Steps

Exploration activities planned for the Lyons River Project include:

  1. An assessment of gravity survey data for the Four Corners and Browns prospect and integration with the IP, magnetics and geochemistry is well underway. Targets generated will be drill tested early in June quarter 2022 following passing of the cyclone season.

  2. A specialist geophysical contractor engaged to conduct surface IP and radial/downhole IP survey has now pushed back to the March quarter 2022 due to unprecedented demand for their services. The IP anomaly NE and SE zones remain open to the east, IP survey lines will be extended further to the east to determine the eventual size of the currently defined 2.5km strike length anomaly.

  3. Heritage surveys are being planned for the drill testing of the Browns prospect and other regional prospects/targets.

Appendix 1: Dalaroo Metals Ltd – Reverse Circulation (RC) Drilling Programme Lyons River Project – Four Corners prospect - JORC Code Edition 2012: 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 (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
x-ray fluorescence (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.
Sampling
was
completed
using
Reverse
Circulation (RC). RC drill samples were collected
at 1m intervals in a cyclone at the side of the
drilling rig and a sub-sample collected via a cone
splitter. A split portion weighing 2-3kg was
collected in numbered sample bags. The
remaining portion was laid out on the ground in
plastic bags for logging. Occasional wet samples
were split, but were collected in plastic bags then
spear sampled.
Four metre composite samples were taken from
1m interval plastic bags using a spear, and
collected in numbered sample bags
All sampling by conventional base metal industry
drilling methods. Duplicate samples collected to
test sample representivity.
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.).
RC drilling used a face sampling bit
Strike Drilling completed the drilling.
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.
Minor wet intervals occur and can affect RC
sample recovery. Chip sample recovery logged.
Sample
recovery
generally
excellent
in
weathered and fresh rocks. Drilling has utilised
RC rig of sufficient size and air capacity to
maximisé recovery and provide dry chip samples.
No indication of sample bias is evident or has
been established

nature. Core (or costean, channel, etc.)
photography.
The total length and percentage of the relevant
intersections logged.
Geological logging of all drillholes included;
lithology,
grainsize,
texture,
deformation,

alteration,
veining,
colour,
weathering.
Chip-trays of samples collected. Drillhole logging
of RC chips is qualitative on visual recordings of
rock forming minerals & estimates of mineral
abundance.
All drillholes were logged in their entirety.
Subsampling
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
subsampling 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 holes sub-sampled by rig mounted cone
splitter and spear.
Sub-sample methods appear appropriate for
deposit and sample type using accepted industry
practices.
RC samples have field duplicate samples taken at
regular intervals and compared.
Samples sub-sampled using accepted splitting
techniques and have been delivered to
laboratory for total preparation by crushing and
pulverisation, before being sub-sampled for
analysis
Sample sizes are generally appropriate for grain
size and 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 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.
Samples to be analysed for Al, Ca, Cr, Cu, Fe, K,
Mg, Mn, Na, P, S, Ti have been determined by
Inductively
Coupled
Plasma
(ICP)
Optical
Emission Spectrometry. Ag, As ,Ba, Li, Mo, Pb, W
and Zn have been determined by Inductively
Coupled Plasma (ICP) Mass Spectrometry
All samples to be analysed by Bureau Veritas

QAQC measures including certified reference
standards and field duplicates samples and
umpire laboratory check samples to be carried
out have shown acceptable levels of accuracy
and precision.

Criteria JORC Code explanation Commentary
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.
Data was captured using Microsoft excel.
Location of
data points
Accuracy and quality of surveys used to locate
drillholes (collar and downhole 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 drillhole collars are surveyed with a handheld
GPS unit with an accuracy of ±5m which is
considered sufficiently accurate for the purpose
of the drillhole. • All co-ordinates are expressed
in GDA94 datum, Zone 51. • Regional
topographic control has an accuracy of ±2m
based on detailed DTM data.
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.
RC drillhole spacing is not regular or grid based,
with the location of individual drillholes
governed by targeting the position of coincident
modelled Induced Polarisation contours, soil
geochem and historical RC and diamond drilling
The Competent Person considers that the
paucity of drilling at Lyons River is insufficient to
establish grade continuity but is indicative of
mineralisation appropriate to an early-stage
exploration project.
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.
The Competent Person has reported downhole
intersections without reference to interpreted
mineralisation orientation. This is appropriate
for an early-stage exploration program where
the orientation of mineralisation is preliminary,
and it is inappropriate to geometrically correct
intersections.
Sample security The measures taken to ensure sample security. Individual calico sample bags from the RC drilling
were placed in polyweave bags and hand
delivered directly to the assay laboratory in Perth
by company personnel.

The results of any audits or reviews of sampling
techniques and data.
None of the drilling has been subject to audit.
The Competent Person does not consider this to
be material for early-stage exploration projects.

Data
aggregation
methods
In reporting Exploration Results, weighting
averaging
techniques,
maximum
and/or
minimum grade truncations (e.g. 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.
In all cases, Exploration Results have been
reported in accordance with Clause 19 of the
JORC Code. Data has been reported as arithmetic
averages,
weighted
by
downhole
drill
intersection
for
identified
zones
of
mineralisation.
No metal equivalent values have been reported.
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 drillhole angle is known, its nature should
be reported.
If it is not known and only the downhole lengths
are reported, there should be a clear statement
to this effect (e.g. ‘downhole length, true width
_not known’). _
All drillhole intercepts/intervals are measured
downhole in metres.
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 drillhole collar locations and appropriate
sectional views.
Appropriate diagrams are included in the main
body of this report
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.
Assay results not reported here.
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
