Highlights

The recent nineteen-hole RC and diamond drill program at Lucky Strike returned multiple high-grade oxide gold intersections that confirm a new, shallow, Banded Iron Formation (BIF) hosted lode

  • Significant new shallow oxide gold intersections include :

  • 19m @ 4.52g/t Au from 45m in LEFR167 incl. 9m @ 8.67g/t Au from 49m

  • 17m at @2.41g/t Au from 111m in LEFR173 incl. 3m @ 10.4g/t Au from 113m

  • 11.1m at 2.47g/t Au from 56.9m in LSRD013 Incl. 4.5m @ 3.73g/t from 63.5m

  • 6m at 4.97g/t Au from 60m in LEFR171

  • These high-grade results are from three close spaced drill sections, including that which hosts LEFR140 (18m @6.57g/t Au), and cover 40m of strike to a depth of 100m

  • The intersections in LEFR167 and LSRD013 support LEFR140 and reinforce the existence of a new, south-east plunging lode within the BIF hosted mineralisation, which is open

  • Planning of additional RC drilling to further evaluate the Lucky Strike trend is underway, with drilling to commence in January 2020

  • Sufficient information is now available at Lucky Strike to allow a resource estimate to be undertaken. This should be completed in the March 2020 Quarter.

ASX Announcement, 20 November 2019

ASX Announcement 20 November 2019

The Board of Lefroy Exploration Limited (ASX: LEX) (“Lefroy” or “the Company”) is pleased to announce results from a recently completed program of reverse circulation (RC) and diamond drilling at Lucky Strike, within the Eastern Lefroy tenement package. Eastern Lefroy is part of the Company’s flagship Lefroy Gold Project (LGP) located 50km to the south-east of Kalgoorlie. Lucky Strike and its strike extensions are wholly within the recently granted (12 April 2019) Mining Lease M25/366.

Lucky Strike is located approximately 35km north east of Gold Fields St Ives processing plant and 5km south west of the Randalls Processing Plant operated by Silver Lake Resources (ASX: SLR). Gold mineralisation at Lucky Strike is hosted within multiple north-west trending Banded Iron Formation (BIF) units. Lucky Strike is approximately 5km along strike to the northwest of the high-grade Lucky Bay open pit, mined by Silver Lake Resources (ASX: SLR) during 2015 (Figure 1). The gold mineralisation at Lucky Bay is also hosted within BIF.

The Lucky Strike Trend was identified by Lefroy as a prospective structural corridor, adjacent to the regional scale Mt Monger Fault (Figure 1), after integration of previous exploration with detailed ground gravity data. Gold mineralisation at Lucky Strike was discovered by the Company in 2017 from wide spaced early stage air core drilling. The area near Lucky Strike is a continued high priority exploration focus for the Company, with gold anomalies identified at Havelock, Neon, Capstan and Erinmore highlighting district scale gold prospectivity (Figure 1).

ASX Announcement, 20 November 2019

ASX Announcement 20 November 2019

Drill Program

The drill program was aimed to further evaluate the interpreted strike and plunge potential of the significant gold mineralisation hosted by the Banded Iron Formation (BIF) intersected in hole LEFR140 in September 2019 (LEX:ASX release 27 September 2019).

The impressive shallow high-grade intersection in LEFR140 (18m @6.57g/t Au from 68m) is hosted within a strongly oxidised BIF unit that was interpreted as the near surface position of a new plunging lode. This lode and the plunge geometry were further supported by the down plunge intersection in LEFR146 (12m @2.97g/t Au from 147m), also in oxide BIF, and which is open. The plunge orientation of this new lode is consistent with that observed from drilling in the main drilled area of Lucky Strike (Figure 3).

The recently completed program design was specifically aimed to gain a stronger appreciation of the extent, geometry and controls of the mineralisation in LEFR 140. This improved geological understanding could then be applied to areas of the BIF along strike where wide spaced drilling had yielded lessor tenor gold intersections but that had similar geological attributes to that observed in LEFR140. The drill pattern was restricted to evaluating the BIF to approximately 100m vertical depth.

The recent program consisted of 18 RC holes for 2029m of drilling on four sections, two of which were existing sections from an earlier program (Figure 2). Two new drill sections were drilled 20m either side of the existing section that hosted LEFR140 (Figure 2 & 3). Hole spacing along each of the new sections and the existing LEFR140 section was at either 10m or 20m centres (Figure 4).

The tight angled drill spacing on LEFR 140 section (Figure 2) was aimed to improve the understanding of the continuity and variability of the high grade mineralisation up and down dip.

To support this detailed RC drilling, a single angled precollared diamond hole LSRD013 was drilled 10m up dip from LEFR140. The hole was RC precollared to 45m and completed with a 39.4m diamond tail. The diamond core sought structural information and the contact relationships of the BIF.

Additional RC drilling was also designed to further evaluate the shallow oxide mineralisation in hole LEFR152 that intersected 22m at 2.49g/t Au from 63m in the prior program. This is interpreted to represent another new lode position at Lucky Strike that occurs at or near the contact of the hanging wall andesite and the metasediments and is open along strike and down dip. Four close spaced RC holes were completed on this section (Figure 2).

Figure 2 Geology and Drill hole plan along the Lucky Strike Trend highlighting the areas of the focused drilling. Drill sections represented as A, B, and C. Refer to Figure 4 for drill section A-A[’]

The drill holes intersected and confirmed a deeply weathered (oxidised) metasedimentary sequence of rocks including BIF, wedged between a hanging wall andesite and footwall basalt (Figures 2 & 4). The metasediment package is preferentially oxidised, particularly the BIF, to at least 200m vertically from surface (Figure 3).

The confined weathering of the BIF is interpreted to represent an oxidation channel down a structure or alteration zone that is open along strike. The BIF is strongly oxidised, maintains a consistent down hole width of approximately 12m and has sharp contact relationships with the hanging and footwall shale units. The main BIF unit at Lucky Strike has a strike length of 740m and is open. Early interpretation by the Company, and recent Company research, suggests these are Algoma type BIF units.

ASX Announcement, 20 November 2019

ASX Announcement

The results from the closed spaced RC and diamond drilling program (Table 1) confirm and reinforce the interpretation of a new BIF hosted plunging lode centered on LEFR140 that is open down plunge. A strong gold intersection was returned from each of the three 20m spaced sections drilled, and one hole (LEFR173) highlights the discovery of a new ore position that is also open.

Significant results returned (Table1) include: -

  • 19m @ 4.52g/t Au from 45m in LEFR167 incl. 9m @ 8.67g/t Au from 49m

  • 17m at @2.41g/t Au from 111m in LEFR173 incl. 3m @ 10.4g/t Au from 113m

  • 11.1m at 2.47g/t Au from 56.9m in LSRD013

  • Incl. 4.5m @ 3.73g/t from 63.5m

  • 6m at 4.97g/t Au from 60m in LEFR171

  • 13m at 1.05g/t Au from 48m in LEFR175

The shallow high-grade intersection in LEFR167 is within a strongly oxidised BIF unit (Figures 3 & 4) that represents the near surface position of a south east plunging lode. This lode and the plunge geometry are further supported by the intersections in LEFR171 and LEFR175, also in oxide BIF (Figure 3) and also open. The plunge orientation of this lode is consistent with that observed from drilling in the main area of Lucky Strike (refer long section).

The geometry of the lode is further supported by LEFR146 which is located approximately 80m down plunge (Figure 3).

The oxide intersection in LEFR173 is interpreted to represent another new lode position at Lucky Strike that is open (Figure 5). The intersection reinforces the variable nature of the gold mineralisation within the BIF, with hole LEFR 172 only 20m up dip not intersecting any mineralisation despite intersecting the BIF of the same geological character.

The confirmation of the plunging high-grade ore zone centered on hole LEFR140, provides support to the Company’s interpretation that there is potential for additional near surface high grade ore shoots along a 400m strike length of the BIF that is only been evaluated by wide spaced RC drilling.

The closer spaced drill test around LEFR140 has delivered additional high-grade intersections but also demonstrated the geometry and extent of the BIF hosted mineralisation (Figure 4). The wide (80m or 160m) spaced drill sections with holes at 40m centres can broadly scope out the extent of the system, it can overlook the short strike length of individual lodes.

Gold mineralisation in the BIF-metasediment package at Lucky Strike now has a strike length of 740m and remains open to the south east (Figures 2 & 3).

Discussion and Next Steps

The results from the recent phase of close spaced RC drilling and the single diamond hole provide further support for the interpretation that Lucky Strike is part of a large, mineralised structural trend. The opportunity is to discover additional high-grade ore shoots or lodes along a BIF unit that is currently only defined by wide spaced RC drilling.

The system has now yielded consistent high-grade gold intersections within deeply oxidised BIF units over the 740m strike length evaluated to date. The system remains open to the south east.

Planning of the next stage of RC drilling is underway and will include closer spaced drilling around the shallow oxide gold mineralisation in LEFR173. This will further expand the ore shoot centered on LEFR140, and test for new shallow ore shoots. This drilling is scheduled to commence in January 2020.

The Company has also commenced resource modelling of the existing drill data and aims to deliver a maiden Lucky Strike resource in the March 2020 Quarter. This will incorporate the January 2020 drilling.

In conjunction with those activities, the Company is now evaluating options to rapidly develop the Lucky Strike and Red Dale Prospects into production, either via a local mill or via a toll treatment facility. Both prospects are contained within granted Mining leases. Lease applications for haulage routes are being actively pursued and the Company could be in a position to be mining before the end of 2020.

JORC CODE, 2012 Edition-Table 1 Report –Lefroy Project –Lucky Strike Prospect October 2019 RC and Diamond Drilling SECTION 1: SAMPLING TECHNIQUES AND DATA

SECTION1: SAMPLING TECHNIQUES AND DATA
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.

The sampling noted in this release has been carried out
using Reverse Circulation (RC) and Diamond drilling (DD)
at the Lucky Strike prospect. The RC program comprised
18 angled holes for 2029m with 1 pre-collar drilled to
45m. The single diamond hole tailed the RC pre-collar to a
depth of 84.4m (39.4m of HQ core). Holes varying in depth
from 75m to 147m with an average depth of 111m. All
holes were drilled -600(dip) toward 0300(Azimuth) spaced
along 10m to 20m centres on lines spaced at a nominal
20m apart.

Sampling and QAQC protocols as per industry best
practice with further details below.

RC bulk samples were collected from the cyclone at 1m
intervals in plastic buckets and arranged in rows of 10 or
20 samples. 2x 1m split samples were collected from 0m
to end of hole (EOH). 1m split samples were collected
directly off the drill rig cone splitter into calico bags
attached to the cyclone. The sample collected generally
weighed 2-3kg. 4m composite samples were collected
using a scoop to produce a 2-3kg sample from 0m to end
of hole collected from the bulk samples. Upon receival of
the 4m composite results 1m samples were then taken
(already collected at time of drilling) from anomalous gold
intervals outlined from the 4m composite samples. The
1m samples were sent to the Laboratory in Kalgoorlie for
analysis. The samples were dried, pulverised, split to
produce a 40g charge for analysis by fire assay with Au
determination by Atomic Absorption Spectrometry (AAS).

DD was conducted utilising triple tube HQ sized core to
obtain the highest quality sample and to minimise core
loss. Due to the oxidised nature of the rock getting reliable
bottom of hole orientation marks was difficult so none
where taken. Core was collected in core trays where it
was marked up and logged by the supervising geologist. It
was noted the there was excellent core recovery and only
minor zones of core loss which were recorded by the
geologist. In order to maximise sample quality, whole core
sampling for the mineralised geological unit was
employed. Samples were collected in calico bags with a
minimum sample width of 0.2m and a maximum 1.2m to
produce a 2-4kg sample through the interpreted
mineralised zone. Once at the lab samples were dried,
crushed and prepared in the sample way as the RC to
produce a 40g charge for fire assay analysis for gold (Au)
byAtomic Absorption Spectrometry (AAS).
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).

The Reverse Circulation (RC) drilling was completed by a
KWL350RC rig from Challenge Drilling (Kalgoorlie). Low air
face sampling hammer drilling proved satisfactory to
penetrate the regolith and reduce contamination risk.

The diamond drilling (DD) was completed by Raglan
Drilling (Kalgoorlie). HQ triple tube was predominantly
used to preserve core integrity and obtain accurate
bottom of hole orientation marks.
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.


All of samples remained dry with good recovery obtained.
Where samples were wet/moist or experienced less than
desired recovery this was instantly evident in size of the
bulk sample laid on the ground and was carefully recorded
by a Lefroy representative on hard copy sample sheets.

Drilling with care (e.g. clearing hole at start of rod, regular
cyclone cleaning) if water encountered, to reduce
incidence of wet –sticky sample and cross contamination,
the cyclone was cleaned out again at the end of each drill
rod.
Criteria JORC Code Explanation Commentary

Below 100m down-hole depth, water ingress into the RC
hole could be problematic, this was anticipated and
measures such as increasing the collar casing depth at the
start of the hole greatly improved the sample quality and
helped keep the samples dry. If the sample was wet this
was recorded by Lefroy field personnel. Insufficient
sample population to determine whether relationship
exists between sample recovery and grade. The quality of
the sample (wet, dry, low recovery) was recorded during
logging.

Diamond core was measured and compared to drilled
interval indicated by the drillers. From this a percentage of
recovery can be calculated. Recovery in oxide material
varied, however where core loss occurred this has been
diligently noted by the drill crew and geologist.

The use of professional and competent core drilling
contractors minimised the issues with sample recoveries.
An honest and open line of communication between the
drill crew and the geologist allowed for a comprehensive
understanding of where core loss may have occurred.

Core recovery in the oxide material was often better in
the mineralised zone due to the fact that the interpreted
host rock is more resistant to weathering. The most
significant grades in this release occur with good core
recovery. Therefore,no significant bias is expected.
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.


Detailed logging of, regolith, lithology, structure, veining,
alteration, mineralisation and recoveries recorded in each
hole by qualified geologist.

Logging carried out by sieving individual 1m sample
cuttings, washing in water and the entire hole collected in
plastic chip trays for future reference for RC drilling.

Every hole was logged for the entire length.

Diamond core underwent detailed logging through the
entire hole with data being transferred to the Lefroy
drilling database after capture

Analysis of rock type, colour, structure, alteration, veining
and geotechnical data were all routinely collected.

Geological logging is qualitative in nature and relies on the
geologist logging the hole to make assumptions of the
core character based on their experience and knowledge.

Recovery, RQD (rock quality designation) and magnetic
susceptibility measurements were recorded and are
considered to be quantitative in nature.

Core within the core trays for each hole was
photographed using a purpose made camera stand and a
quality digital SLR camera and stored in the database.

All drill holes were logged in their entirety (100%).
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.

Sampling of 1m intervals directly off a rig-mounted cone
splitter into two separate calico bags. Sample weight 2 - 3
kg. A 4m composite sample was collected, from 0m to
EOH for each hole. The composite samples were collected
by using a scoop to collect a representative “split” from
each bulk sample that made up a 4m composite interval,
this was placed into a pre-numbered calico bag. Pre-
numbered calico bags containing the samples were
despatched to the laboratory for assay. Upon receival of
results for 4m composite samples, selected 1m resplit
samples (collected at cyclone) were collected in the field
for submission by the same fire assay technique.
• The sample preparation of the RC samples follows
industry best practice, involving oven drying, pulverising,
to produce a homogenous sub sample for analysis.
• Along with submitted samples, standards and blanks were
inserted on a regular basis where the pre-numbered calico
bag ended with the numbers 20, 40, 60, 80 and 100.
Standards were certified reference materialprepared by

Geostats Pty Ltd.Duplicate samples were collected at
zones of interest and at irregular intervals of about 2 per
hole.

Whole core sampling was employed to maximise sample
quality and to reduce bias. This was largely due to the
nature of the material being sampled and its proclivity to
“washing away” when cut using a saw which uses water to
assist the blade in cutting.

Certified reference material (CRM) standards and blanks
were inserted at the geologist’s discretion on a roughly 1
in 20 sample bases.
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.


Samples routinely analysed for gold using the 40gram Fire
Assay digest method with an AAS finish at Bureau
Veritas’s Kalgoorlie Laboratory.

Quality control process and internal laboratory checks
demonstrate acceptable levels of accuracy. At the
laboratory regular assay repeats, lab standards, checks
and blanks were analysed.
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.

The results have been reviewed and verified by alternative
company personnel.

No holes were planned to twin prior drill holes.

Capture of field logging is electronic using Toughbook
hardware and Logchief software. Logged data is then
exported as an excel spreadsheet to the Company’s
external database managers which is then loaded to the
Company’s DATASHED database and validation checks
completed to ensure data accuracy. Assay files are
received electronically from the laboratory and filed to
the Company’s server, and provided to the external
database manager.

There has been no adjustment to the assay data. The
primary gold (Au) field reported by the laboratory is the
priority value used for plotting, interrogating and
reporting.
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.

Drill hole positions were surveyed using a DGPS operated
by a third-party contracting surveyor. The same
contractor was used once drilling was completed to pick-
up collar positions using a DGPS. Down holes surveys were
completed by Challenge and Raglan drill crew using a gyro
and recording a survey every <30m down the hole.

Grid System – MGA94 Zone 51. Topographic elevation
captured byusingthe differential GPS.
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.

Hole spacing at nominal 10m to 20m centres on 0300
orientated drill lines with line spacing 20m around
previous Lefroy drilling.

Mineralisation at Lucky Strike is constrained to a particular
iron rich geological unit logged as a BIF (banded iron
formation). Holes were sampled using 4m composite
samples for the entire length of the hole. Where SIF was
logged by the geologist and/or >0.1g/t Au in collected 4m
composite samples was intercepted, 1m samples were
collected and sent to the laboratory for analysis by fire
assay.
Criteria JORC Code Explanation Commentary
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 North-East orientated drill traverses considered
effective to evaluate the roughly North-West trending
banded iron formation (BIF) stratigraphic unit which is
interpreted to be the prospective host rock. The RC drill
holes were intended as follow-up work to assess previous
Lefroy AC and DD drill holes which were orientated on
East-West drill lines which intercepted high gold grades
and favourable geology.
• The drill orientation is a more effective test of “true”
width of the host rock due to the fact the host rock unit is
striking roughly North-West/South-East.
Sample security • The measures taken to ensure sample
security.

Samples were bagged in labelled and numbered
polyweave or plastic bags, collected and personally
delivered to the Bureau Veritas Laboratory (Kalgoorlie) by
Company field personnel. Samples were then sorted and
checked for inconsistencies against lodged Submission
sheet by Bureau Veritas staff.

Bureau Veritas checked the samples received against the
Lefroy Exploration Limited (LEX) submission sheet to
notify of any missing or extra samples. Following analysis,
the sample, pulps and residues are retained by the
laboratoryin a secure storageyard.
Audits or reviews • The results of any audits or reviews of
sampling techniques and data.

All sampling and analytical results of the drill program
were reviewed by the Senior Exploration Geologist and
Managing Director. Anomalous gold intersections were
checked against library chip trays to correlate with
geology. No specific audits or reviews have been
conducted.

Mineral tenement
and land tenure
status
• Type, reference name/number, location
and ownership including agreements
or material issues with third parties
such as joint ventures, partnerships,
overriding royalties, native title
interests, historical sites, wilderness or
national park and environmental
settings.
• The security of the tenure held at the
time of reporting along with any
known impediments to obtaining a
licence to operate in the area.

The Lefroy Project is located approximately 50 km in
south east from Kalgoorlie, Western Australia and
consists of a contiguous package of wholly owned
tenements held under title by LEX or its wholly owned
subsidiary Monger Exploration Pty Ltd. The work
described in this report was completed on a Mining
lease M 25/366.

M25/366 is held 100% by Monger Exploration Pty Ltd
a wholly owned subsidiary of Lefroy Exploration
Limited
• The tenements are current and in good standing with
the Department of Mines and Petroleum (DMP) of
Western Australia.
Exploration done by
other parties
• Acknowledgment and appraisal of
exploration by other parties.

Some previous exploration work was completed on
the Lucky Strike trend by Integra Mining Limited,
Western Mining and Octagonal Resources. The bulk of
this work included phases of Aircore (AC). This work
identified mineralisation along the trend, however no
previous explorer identified mineralisation at Lucky
Strike and as such this is a new discovery by Lefroy
Exploration.
Geology • Deposit type, geological setting and
style of mineralisation.

The Lefroy Project is located in the southern part of
the Norseman Wiluna Greenstone Belt and straddles
the triple junction of three crustal units, the Parker,
Boorara and Bulong Domain. The Lefroy project
tenements are mostly covered by alluvial, colluvial
and lacustrine material with very little outcrop. Lucky
Strike is hosted in banded iron formation within a
thin (<300m approx.) package of metamorphosed
sediments, sandwiched between basalt and high Mg
basalt stratigraphy. It lies proximal to the GSWA’s
interpreted position for the domain bounding north-
west trending Mount Monger Fault. It is unknown
what the relationship is between these sediments
and the surrounding mafic stratigraphy and how that
fits in with the well-studied stratigraphy of the
Kalgoorlie Terrane.
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:
• easting and northing of the drill hole
collar
• elevation or RL (Reduced Level –
elevation above
sea level in metres) of the drill hole
collar
• dip and azimuth of the hole
• down hole length and interception
depth
• 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.
• Table containing drill hole collar, survey and
intersection data for material (gold intersections
>0.25gpt Au with a max of 2m internal dilution) drill
holes are included in the Table in the body of the
announcement.
• No Information has been excluded.
Criteria JORC Code Explanation Commentary
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.



All report grades have been length weighted. High
grades have not been cut. A lower cut off of 0.25gpt
Au has been used to identify significant results
(intersections).

Where present, higher grade values are included in
the intercepts table and assay values equal to or > 1.0
g/t Au have been stated on a separate line below the
intercept assigned with the text ‘includes’.
• Reported RC results have been calculated using 1m
split samples. No metal equivalent values or formulas
used.
• Reported diamond drill results have been results have
been calculated using samples that vary in length from
0.2m to 1.2m but nominally 0.5m. No metal equivalent
values or formulas used.
• Where core loss is measured, a gold value of 0 ppm is
applied for the length weighted interval for which this
would apply and included in the intercept calculation
and would count in the internal dilution.
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 results are based on down-hole metres.
• Previous drill coverage has provided guidance for the
presence of steeply dipping stratigraphy comprising a
sedimentary package of rocks containing banded iron
formations (BIF) which provide a good host rock for
gold mineralisation. A ground magnetic survey
completed in 2018 over the area of interest confirms a
NW strike of the magnetic sediments within the
stratigraphy and hence has guided the orientation of
drilling for this program. Structural measurements on
orientated diamond drill core from a previous Lefroy
Exploration drill program also assisted in decided
which orientation to drill these follow up RC holes.
Results from this drill program do not represent ‘true
widths’ however holes are designed to intercept the
host sequenceperpendicular to its strike.
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.

• Appropriate summary diagrams (section & plan) are
included in the accompanying announcement.
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.
• Significant assay results are provided in Table 1 for the
recent LEX RC drill program.
• Drill holes with no significant results are not reported.
• Significant assay results from historical drilling are
noted in the body of the report.
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.

All relevant data has been included within this report.
Further work • 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
geological interpretations and future
drilling areas, provided this information is
not commercially sensitive.
• The appropriate next stage of exploration planning is
currently underway and noted in the body of the
report.
