Aircore Drill Results Enhance the Lucky Strike Trend

Key Points

  • Results from an aircore drilling program along the Lucky Strike Trend at the Company’s flagship Lefroy Gold Project have extended and improved geological controls on the emerging gold trend

  • The 33 hole drill program evaluated the strike and down dip continuity of key intersections reported in April 2017 of 10m at 4.60g/t Au from 24m in LEFA 171, and 11m at 3.53g/t from 60m in LEFA 136, both holes ending in mineralisation

  • Significant intersections from 1m resamples from the recent phase of drilling include:6m at 2.77g/t Au from 52m in LEFA 240 8m at 2.23g/t Au from 45m in LEFA 254 6m at 1.00g/t Au from 81m in LEFA 238

  • Results from holes LEFA240 & 254 have highlighted gold mineralisation hosted within a magnetite bearing sedimentary iron formation (SIF)

  • The recent drilling has advanced the geological model, demonstrating gold mineralisation is hosted within a SIF unit similar to that hosting the Lucky Bay gold deposit 2km to the south east

  • Interpretation of the geology further supports an emerging gold mineralised trend defined over a 4500m strike length hosted within a package of sedimentary rocks, coincident with the regional Mt Monger Fault

ASX Announcement 7 July, 2017

The Board of Lefroy Exploration Limited (ASX: LEX) (“Lefroy” or “the Company”) is pleased to announce the assay results from a follow up aircore drilling program along the Lucky Strike Trend at its flagship Lefroy Gold Project (“LGP or Project”), located approximately 50km to the south east of Kalgoorlie.

The Lucky Strike Trend is located approximately 2km to the northwest of the high grade Lucky Bay open pit mined by Silver Lake Resources (ASX:SLR) during 2015 and 4km to the south west of the Randalls Processing Plant operated by SLR (Figure 1). The Company has interpreted from geophysical and geological data that the Lucky Strike Trend shares a similar geological and structural setting to Lucky Bay, being adjacent to the regional Mt Monger Fault that separates mafic units of the Bulong Antiform to the north and metasedimentary rocks to the south.

PROGRAM.

The focused aircore drilling program consisting of 33 angled drill holes totaling 2148m was completed in June to follow up positive gold results from the early stage reconnaissance air core drill program completed in April 2017. The results from that program returned 11m at 3.53g/t Au from 60m to End of Hole (EoH) in LEFA136 ( Figure2), and 10m at 4.60g/t from 24m to EoH in LEFA171 (Figure 2) and demonstrated the emergence of a 3000m gold trend within sedimentary rocks adjacent to the regional Mt Monger Fault. The recent program was aimed to close the drill spacing along the trend to 160m line and 80m hole centres and to complete closer spaced drilling around LEFA 136 and 171 in order to provide further clarity on the geological controls of the mineralisation. This infill drilling was to mainly 20m along these key sections but also 80m step out sections along strike with the aim to constrain the mineralisation.

Figure 2. Inset Map-Lucky Strike Trend showing previous drill holes, June drill program drill holes, new gold intersections and proximity to the Lucky Bay open pit. Refer Figures 3 & 4 for drill sections A-A’ and B-B’.

The results from this phase of drilling has provided further important information on the host sequence and style of gold mineralisation providing confidence in the geological model and forming the basis for further exploration. The infill drilling around both LEFA 136 and 171 has returned positive results (Table 1) from 1m samples from the air core drill program and has demonstrated how constrained the gold mineralisation is within the oxide zone. Follow up 20m spaced drill holes around LEFA 136 returned 6m at 2.77g/t Au from 52m in LEFA240 ( Figure 3), hosted within an oxidised sedimentary iron formation (SIF) within a sequence of black shale. Closer spaced drilling along the LEFA 171 section (Figure 4) returned 8m at 2.23g/t Au from 45m in LEFA 254, and this hole has demonstrated the down dip extension of mineralisation in LEFA 171, again hosted by a SIF, within a sequence of black shale.

This tighter spaced aircore drilling has improved the understanding the evolving geological model, by demonstrating the geometry of the host unit, but also highlights the limited nature of the dispersion of gold in the oxidised rock and how this then needs to be taken into consideration for further exploration. The recent closer spaced drilling has demonstrated that this style of mineralisation can easily be missed with wider spaced drilling and by not appreciating the regolith environment.

Drill traverses 80m along strike of the LEFA 136 and 171 section lines did not intersect the same tenor of grade within a similar stratigraphic sequence, but can explained by the wider(40m) spaced drill holes.

The recent program has provided a greater understanding of the geological framework along the 3000m trend defined in the LEX tenure (Figure 5). Gold mineralisation is constrained to one or two near vertical dipping sedimentary iron formation (SIF) units within a sequence of black shale. This sedimentary sequence is in contact to the east with a package of mafic rocks consisting of high Mg basalt and dolerite, being part of the Bulong Antiform. This contact zone is the interpreted position of the Mt Monger Fault, a major regional structural trend, similar to the Boulder Lefroy Fault, and the Zuleika Shear as recognised by the Geological Survey of Western Australia (GSWA). Major gold deposits are associated with and proximal to the Boulder Lefroy and the Zuleika structures in the Kalgoorlie area.

The geological sequence at Lucky Strike and the mineralisation intersected is considered remarkably similar to the Lucky Bay gold deposit located approximately 2km along strike to the south east. There, gold mineralisation is hosted by a highly oxidised sedimentary iron formation within a sequence of black shale. It demonstrates the emergence of gold mineralisation along a 4.5km trend from Lucky Bay to the northwest along the Lucky Strike Trend, and coincident with the interpreted position of the Mt Monger Fault. This trend is further supported by interpretation of imagery from the Company’s ground gravity database, which highlights a gravity low along the mineralised trend. This new information now provides preliminary evidence of gold mineralisation along the Mt Monger Fault on a regional scale and suggests that the fault maybe of similar prospectivity to the Boulder Lefroy or Zuleika shear.

FUTURE WORK PROGRAM

The Company is very encouraged by the recent results and the advancing geological model along the Lucky Strike Trend. The small focused drilling program has not only extended the anomaly but delivered important geological information that not only constrains the mineralisation but places it in a regional context.

Planning for the next phase of exploration at Lucky Strike has already been initiated with a Programme of Works for Exploration already been lodged with the Department of Mines (DMP) for diamond drilling. In addition processing of infill ground gravity data collected in June along the northwest extension of the trend and at Lake Randall is in progress, this new data will provide a focus for extensional air core drilling.

Diamond drilling is being considered as part of the next phase of exploration at Lucky Strike to provide confirmation to the controls on the mineralisation and its depth extensions but supported by a combination of infill closer spaced aircore and deeper reverse circulation drilling. This work program is expected to commence in the September Quarter.

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 AirCore (AC) drilling
at the Lucky Strike Prospect. The AC
program comprised 33 angled holes for
2148m, holes varying in depth from 12-
114m with and average depth of 65m. All
holes were drilled -600to 0900at 40m-80m
centres that infilled between the existing
lines to 80m or 160m

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

AC samples were collected from the
cyclone at 1m intervals and laid out in
rows of 10 or 20m (10-20 samples) on the
ground. Composite 4m samples were then
collected by scoop sampling the 1m piles
with a flour scoop to produce a bulk 2-3kg
sample which was sent to the Laboratory
in Kalgoorlie for analysis. Samples were
dried, pulverised, split to produce a 40g
sample for analysis by fire assay with Au
determination
by
Atomic
Absorption
Spectrometry. Anomalous (assays >0.10g/t
Au) composite samples were resampled as
individual 1m samples and collected by the
same scoopsample technique.
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
Raglan Drilling (Kalgoorlie). The AC drill bit
has a diameter of 78mm 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 blade refusal and hence terminates in
fresh or hard material such as quartz
Drill sample

• 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. Minor

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 by
alternative company personnel and minor
sampling errors identified were field
checked and corrected.

No holes were twinned.

Capture of field logging is electronic using
Toughbook
hardware
and
Logchief
software. Logged data is then exported as
an excel spreadsheet to the Companys
external database managers which will be
loaded to the Company’s DATASHED
database and validation checks completed
to ensure data accuracy. Assay files are
received electronically from the laboratory
by the Managing Director and filed to the
companys 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. Drill
azimuth is set up by the supervising
geologist.
No
downhole
surveys
completed.

Grid System – MGA94 Zone 51.

Topographic elevation captured by using
reading from Garmin hand held GPS with
an accuracy of+-10m and considered
suitable for the flat terrain.
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 80m centres on
new in fill east west orientated drill lines
with line spacing’s varying from 80m to
160m. Infill drilling to 20-40m centres on
selected locations on existing sections.

AC samples composite range 1-4m but
generally 4m. No assay compositing has
been applied.
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 north
westerly trending geology and regional Mt
Monger Fault which has been interpreted
from aeromagnetic and gravity data. Drill
holes
are
reconnaissance
and
are
orientated
appropriately
to
ensure
unbiased sampling of the geological trends
• The AC drilling is reconnaissance in nature,
being relatively wide spaced and the
orientation
of
the
gold
mineralised
structures intersected is yet to be
confirmed. Initial interpretation suggests
vertical dipof the stratigraphy.
Sample security • The measures taken to ensure sample security.
Individual composite samples and 1m
resamples were bagged in plastic bags,
collected and personally delivered to the
Bureau Veritas Laboratory in Kalgoorlie by
the LEX Field Supervisor.

Bureau Veritas check the samples received
against the LEX 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
by
the
Senior
Exploration
Geologist and Managing Director, and
anomalous gold intersections inspected in
the field to correlate with geology. No
specific site audits or reviews have been
conducted.

Section 2: REPORTING OF EXPLORATION RESULTS – LEFROY PROJECT-Lucky Strike Prospect as at 7 July 2017

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 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 Exploration Licence
E26/182 and E26/183 held 100% by 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.

At the Lucky Strike Prospect the key
exploration in the area was by Integra
Mines limited in 2010 and this drill program
is well reported in a report to the
Department of Mines and Petroleum
WAMEX report A104013. This report clearly
documents the air core drill program that
resulted in the intersection in hole SCA794.
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 Lucky Strike
area being predominantly metasediments,
and basalt. The key structural element at
Lucky Strike is the north west trending Mt
Monger
Fault
separating
the
mafic
lithologies to the north in the Bulong
domain to the metasediments to the south.
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 >0.10gpt Au) drill holes are
included in the Table 1 in the body of the
announcement.
• No Information has been excluded.
• There are historical drill holes within the
Lucky Strike Prospect and these are depicted
on the drill hole plan in the announcement.
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 0.5gpt Au has been used to identify
significant results depicted on Figures in the
text. These are considered significant given
the first pass reconnaissance nature of the
drilling.

Table 1 in the body of the report presents all
individual composite results greater than
0.10g/t Au
• Reported AC results have been calculated
using a minimum intercept width of 1m.
Anomalous composite samples have been
resampled

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 individual assay results are
provided in Table 1 for the recent LEX drill
program.
• Drill holes with no significant results are not
reported.
• Significant assay results from historical
drilling are noted in the text and figures in
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.
• Follow up infill air core drilling is being
considered for the Lucky Strike Prospect
Diamond Drilling to confirm the geology and
geometry of the stronger mineralisation is
being planned .
