ASX RELEASE-29 June 2020

Multiple Large Gold Anomalies Confirmed at the Western Lefro JV y

Aircore

  • Validated results have been received from JV partner Gold Fields for an additional 66 aircore drill holes drilled within the Western Lefroy JV Project. The results are as at 3 June 2020 and cover the multi-target program completed in April

  • The early stage drilling complements the extensive 2019 foundation aircore program to obtain geological and geochemical information beneath the surfaces of Lake Lefroy and the adjacent Lake Randall. The additional results extend and enhance existing targets and include:

  • 5m @ 1.85g/t Au from 84m in SAL1741

  • 2m @ 1.86g/t Au from 58m in SAL1726

  • 2m @ 1.45g/t Au from 16m In KD81785

  • 4m @ 0.56g/t Au from 82m in KD81790

  • 7m @ 0.35g/t Au from 84m in SAL1739

  • The significant results from holes SAL1741 and SAL1726 further support the large Eastern Shoreline Trend that now has an extensive 7km strike length.

  • The program has also enhanced an existing anomaly now known as LLT08 that has a 1500m strike length located adjacent the interpreted regional Woolibar Fault

  • The results from the recent program have provided further encouragement and information to guide a phase of RC drilling to evaluate multiple targets. This drilling is scheduled to commence in July

  • The tenor and extent of gold results have provided support for EIS co-funding for four deep diamond drill holes totaling 1600m along the new Eastern Shoreline Trend. These holes are expected to be completed by December 2020

  • Gold Fields has completed the AUD$4million minimum exploration spend and is required to fund an additional AUD$6million for AFY2021 to earn a 51% WLJV interest

Lefroy Exploration Managing Director, Wade Johnson said “we are highly encouraged by the recent air core drilling results from holes that are 200m apart that have reinforced and extended multiple large regolith gold anomalies in Lake Lefroy. We keenly await the commencement of the next drilling campaigns by Gold Fields that will provide a deeper evaluation of the anomalies”

ASX Announcement 29 June 2020

Lefroy Exploration Limited (ASX: LEX) (“Lefroy” or “the Company”) is pleased to provide and update to activities on the Western Lefroy JV tenement package. Importantly, Gold Fields Limited (NYSE: GFI) (“Gold Fields”) has provided an export of validated drill results from the aircore (AC) drilling program completed in April 2020 on the Company’s tenements over Lake Lefroy and the adjacent Lake Randall (Figure 1).

The recent drilling program complements the major phase of foundation aircore drilling that commenced in late January 2019 and is part of the $25million Farm-In and Joint Venture (JV) agreement between Lefroy and Gold Fields that commenced in June 2018.

The tenements form part of the Western Lefroy tenement JV package that cover 372km[2] adjoining the St Ives gold camp (Figure 1). Western Lefroy is part of the wholly owned greater Lefroy Gold Project (LGP) located 50km south east of Kalgoorlie. The Company maintains exploration at the non-JV Eastern Lefroy which covers priority prospects at Lucky Strike, Red Dale and Hang Glider Hill (Figure 1).

ASX Announcement 29 June 2020

Drill Program

Gold Fields commenced the major full field aircore (AC) drilling program in late January 2019 (refer: LEX ASX release 31 January 2019). That initial program involved completing approximately 350 vertical holes spaced 200m apart on broad traverses up to 1km apart to cover most of the JV tenure in Lake Lefroy, and the adjacent Lake Randall using a specialised lake drilling rig.

In August 2019 Gold Fields completed the aircore (AC) drilling program on tenements within Lakes Lefroy and Randall with 776 vertical air core holes totaling 40,421m being completed. The program yielded foundation geological and geochemical information that has been interrogated in conjunction with the geophysical data to deliver specific drill targets for deeper drill testing and hence termed foundation drilling.

The results of that foundation drilling program yielded multiple new gold anomalies in Lake Lefroy and expanded the footprint of the anomalies identified by the Company during its 2017 lake drilling campaign. These include the Zanex, LLT04, and the LLT06 prospects (Figure 2).

New areas of regolith hosted gold mineralisation were outlined in Lake Lefroy but also from wide spaced initial drilling in the adjacent Lake Randall. The key new anomaly in Lake Lefroy is known as Eastern Shoreline (Figure 2) where a linear gold trend has now been defined over a 7000m strike. Better results from this trend include 7m at 0.70g/t Au from 74m in SAL1467 and 6m at 1.53g/t Au from 88m in SAL1533.

In April 2020 Gold Fields initiated and completed an aircore drill program designed to improve and extend the Eastern Shoreline, and a number of other anomalies with both infill and extensional drilling in both Lake Lefroy and Lake Randall (refer LEX ASX release 30 March 2020). That program resulted in the drilling of 66 vertical for 4300m evaluating seven target areas.

The drill density is still considered wide spaced with infill drill traverses at 200m or 400m spacings and holes centres at a nominal 200m apart. The wide spacing of the drill holes is designed to conduct effective first pass reconnaissance to screen large areas. All holes were drilled to blade refusal and penetrate a variable thickness of transported cover and oxidised bedrock.

The results (Table 1) from the 66 holes are considered very encouraging given the wide spaced early stage design of the program and include:

  • 5m @ 1.85g/t Au from 84m to End of Hole (EOH) in SAL1741

  • 2m @ 1.86g/t Au from 58m in SAL1726

  • 2m @ 1.45g/t Au from 16m In KD81785

  • 4m @ 0.56g/t Au from 82m in KD81790

  • 7m @ 0.35g/t Au from 84m in SAL1739

  • 8m @ 0.25g/t Au from 78m in SAL1763

Figure 2 Drilling plan highlighting recent and prior drill holes completed in Lake Lefroy key gold prospects identified

The key results from the drilling have extended and enhanced the Eastern Shoreline trend, but also further developed and existing irregular anomaly now known as prospect LLT08 that is located adjacent to the interpreted Woolibar Fault (Figure 2).

The Eastern Shoreline gold trend now has an extensive strike length of 7km based on maximum gold in aircore holes (Figure 2). The recent gold intersection in SAL1741 comes from the southern end of the trend and is supported by an earlier intersection of 6m @1.53g/t Au in SAL1533, located 400m to the south. The drill density in this area has east west drill lines spaced 400m apart and hole centres 200m apart. The dominant rock type along the trend is recorded as either sandstone or siltstone, that is in contact with a mafic unit (basalt) to the West.

Twelve holes drilled to follow up prior aircore gold anomalies from the 2019 drill campaign have enhanced and extended the prospect now known as LLT08 (Figure 2). The gold anomaly has a strike length of approximately 1500m and a width of 1000m. Encouraging results from the wide spaced drilling include the intercepts in holes KD81785, KD81790 and SAL1763. The geology at LLT08 is characterised by a sequence of altered metasedimentary rocks, that are covered by up to 90m of transported cover.

ASX Announcement 29 June 2020

Next Steps

Planning and preparations for a reverse circulation (RC) drill program are well underway. The program is due to commence in early July and will evaluate multiple targets generated by integration of the foundation aircore drilling and high-resolution geophysical programs completed in 2019. The gold anomalies and trends defined by the wide spaced air core drilling broadly outline the extent of the gold anomalism in the regolith (oxidised rock). RC drilling is now required to undertake a deeper test beneath these regolith gold systems by penetrating well into the fresh rock to search for the primary source.

To assist in advancing the geological model beneath the eastern shoreline of Lake Lefroy Gold Fields were successful in a proposal for a co-funded diamond drilling program, under Round 21 of the Government of Western Australia’s, Exploration Incentive Scheme (EIS). The drilling will involve the drilling of four 400m diamond drill holes totaling 1600m on a single traverse over the Eastern Shoreline Trend (Figure 2). Program commencement is to be scheduled but will be completed by the end of the December 2020 quarter.

Background to the Western Lefroy JV (WLJV)

The Western Lefroy tenement package is a Joint Venture with Gold Fields which commenced on 7 June 2018 (ASX: LEX 7 June 2018). Gold Fields can earn up to a 70% interest in the Western Lefroy tenements by spending up to a total of AUD$25million on exploration activities within 6 years of the commencement date. This includes a minimum expenditure requirement of $4 million within 2 years before Gold Fields can elect to withdraw.

Gold Fields has met the minimum exploration commitment of $4million before withdrawal. This was a requirement of the Stage 1 earn in commitment to sole fund $10million to earn a 51% interest in the joint venture. Gold Fields are required to fund an additional $6million for AFY2021 to earn that 51% WLJV interest.

Gold Fields is globally diversified gold producer with nine operating mines in Australia, Peru, South Africa and West Africa (including the Asanko JV), as well as one project in Chile. It has a total attributable annual gold-equivalent production of 2.2million ounces, attributable gold-equivalent Mineral Reserves of 51.3Moz and Mineral Resources of 115.7Moz. Mining assets in Australia include a 100% interest in the St Ives, Agnew and Granny Smith mines in the Eastern Goldfields of Western Australia, with a combined annual production of approximately 935koz. Gold Fields also has a 50% interest in the Gruyere mine with Gold Road Resources (ASX: GOR) also in the Eastern Goldfields.

Gold Fields commenced exploration on Western Lefroy in July 2018 involving multidisciplinary ground and airborne geophysical surveys (gravity and magnetics) primarily located on or near Lake Lefroy. Those surveys built upon the data collected by the Company in 2017 to deliver a foundation detailed geophysical dataset used for target identification.

To complement this foundation geophysical data, Gold fields commenced a large full field aircore drill program on Lake Lefroy within the Western Lefroy JV tenements between January and August 2019.

JORC CODE, 2012 Edition-Table 1 Report –Lefroy Project – Gold Fields Western Lefroy JV – 29[th] June 2020 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 by Joint Venture partner
Gold Fields Limited utilising Air Core (AC)
drilling on Lake Lefroy, targeting potential
structural corridors prospective for gold
mineralisation. The hole spacing was
nominally 200m apart on traverses located
400m apart that has been infilled in places
to 200m between lines.

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

AC samples were collected from the
cyclone at 1m intervals. Library samples
were collected in calico sample bags for
future detailed sampling if required.
Composite
2m
samples
were
then
collected by scoop/spear to produce a bulk
2-3kg sample which was sent to the ALS
Laboratory in Kalgoorlie for analysis.
Samples were dried and pulverised to
produce a 50g sample for analysis by fire
assay with Au determination by Atomic
Absorption Spectrometry.
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 Aircore (AC) drilling was completed by
contractor Ausdrill. The AC drill bit has a
diameter of 100mm and collects samples
through
an
inner
tube
to
reduce
contamination, but also allows better
penetration through any palaeochannel
puggy clays and fine sands. Aircore drilling
is to blade refusal and hence terminates in
fresh rock or hard material such asquartz.
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.

The majority of the samples collected from
the AC drill program were dry to moist.
Drilling took place on Lake Lefroy and the
initial transported material (i.e. lake
sediments) were wet with some muddy
samples, which can result in poor recovery.
Samples below the transported material
were moist/dry with minor AC samples
being wet at the base of the holes. Sample
recovery below the base of alluvium (BOA)
was considered appropriate with some
samples dry with good sample recovery.

Sample recovery size and sample condition
(dry, wet, moist) recorded. Recovery of
samples estimated to be 20-100%, with
limited
recovery
particularly
drilling
through the surficial lake clays and puggy
moist transported clays.

Drilling with care (eg. clearing hole at start
of rod, regular cyclone cleaning) if water
encountered to reduce incidence of wet –
sticky sample and cross contamination.

for instance results for field duplicate/second-half
sampling.
• Whether sample sizes are appropriate to the grain size
of the material being sampled.


No core drilling completed

Composite samples of 2m were collected by
scoop/spear or grab (sticky clays) sampling
2m intervals into pre-numbered calico bags.
Sample weight 2 - 3 kg. The last interval of
each hole was a specific 1m. Samples placed
in polyweave bulka-bags for despatch to
assay laboratory.
• The sample preparation of the AC follows
industry best practice, involving oven drying,
pulverising, to produce a homogenous sub
sample for analysis.
• Along with composite samples, standards
and
blanks
were
randomly
inserted
(approximately every 40 samples) and were
included
in
the

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 50gram Fire Assay digest method with an
AAS finish at ALS (Kalgoorlie) Laboratory. A
Bottom of Hole (BOH) sample was also
collected and sent to ALS (Perth) Laboratory
for multi-element analysis by 4 acid digest
with ICP-MS/OES finish.

No geophysical tools, spectrometers or hand
held XRF instruments used.

and
internal
laboratory checks demonstrate acceptable
levels of accuracy. At the laboratory,
regular assay repeats, lab standards, checks
and blanks are 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 checked
by alternative Gold Fields personnel.
• No holes were twinned

Capture of field logging is electronic using
Toughbook hardware and Logchief software.
Logged data is then exported to Gold Fields
DATASHED database and validation checks
completed to ensure data accuracy. Assay
files are received electronically from the
laboratory by the database administrators
and filed to the Gold Fields server.

There has been no adjustment to the assay
data. The primary Au field reported by the
laboratory is the 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
hand-held Garmin GPS with a horizontal
(Easting Northing) accuracy of +-5m. No
downhole surveys completed.

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 200m centres on
new east west orientated drill lines with
nominal line spacing of 400m. This has
been infilled in places to 200m between
lines.

AC samples composite nominally 2m
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 East West orientated drill traverses
considered effective to evaluate the
northerly-north westerly trending geology
Drill holes are reconnaissance and are
orientated
appropriately
to
ensure
unbiased sampling of the geological trends
• The AC drilling is reconnaissance in nature,
being wide spaced and the orientation of
the deformed rocks intersected is yet to be
confirmed.
Sample security • The measures taken to ensure sample security.
Individual composite samples were bagged
in polyweave bulka-bags, collected and
delivered to the ALS Laboratory in
Kalgoorlie. Samples were sorted and
checked
for
inconsistencies
against
submission sheet by ALS staff at the
Kalgoorlie laboratory.

ALS check the samples received against the
sample submission form to notify of any
missing
or
extra
samples.
Following
analysis, the sample pulps and residues are
retained by the laboratory in a secure
storageyard.
Audits or
reviews
• The results of any audits or reviews of sampling
techniques and data.

All results of this drill program were
reviewed and validated by Gold Fields
Personal. No specific site audits or reviews
have been conducted. A validated data
export was provided to the Company on
3rd June 2020. The data was reviewed by
the CompanyManagingDirector.

Section 2: REPORTING OF EXPLORATION RESULTS – LEFROY PROJECT- Gold Fields Western Lefroy JV as at 29[th] June 2020

Criteria JORC Code Explanation Commentary
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 Goldfields Western Lefroy
JV 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’s
Hogans
Resources Pty Ltd. The work described in this
report was undertaken on Prospecting leases
P26/3889, P26/3890 and Exploration Licences
15/1447 & E26/184 held 100% by Lefroy
Exploration Limited but operated by Goldfields
St Ives Pty as part of an earn-in joint venture
agreement.
• 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.

Within Lake Lefroy and along the interpreted
Woolibar Trend the key exploration in the
area now known as Zanex was completed by
Cyprus Gold Australia Corporation in 1997 and
this drill program is well documented in a
report to the Department of Mines and
Petroleum WAMEX report A52840.
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.
The project is underlain by a folded and fault
bounded sequence of Archaean rocks, and in
the Woolibar trend within Lake Lefroy area
being predominantly metasediments, High Mg
basalt and basalt. The key structural element
is the interpreted North West trending
Woolibar Fault.
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 >0.10g/t Au) drill holes are
included in the Table in the body of the
announcement.
• No Information has been excluded.

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.
• There is no weighting or averaging of the
reported grades. High grades have not been
cut. A lower cut off of 0.10g/t Au has been
used to identify significant results in Table 1.
These are considered significant given the
first pass reconnaissance nature of the
drilling.
• Where present, higher grade values are
included in the intercepts table and assay
values equal to or > 1.0 g/t Au with a max of
2m internal dilution
• No metal equivalent values or formulas
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 results are based on down-hole metres.
• Given the wide spaced reconnaissance
nature of the drilling the geometry of the
mineralisation reported is not sufficiently
known and the true width is not known
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 entire drill program.
• Drill holes with no significant results are not
reported.
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 data will be reviewed on completion of
the current program, if warranted further
programs will be designed as follow-up.
