Highlights
A 3120-sample point auger geochemical program has been completed over a large contiguous tenement package straddling the regional Mt Monger Fault at Eastern Lefroy.
-
The program evaluated 17 kilometres of strike extending between the Hang Glider Hill prospect and Lucky Strike gold deposit
-
The objective was to generate drill targets from gold anomalies that may represent the surface expression of bedrock gold systems along this trend
-
Five new strong surface gold anomalies identified near to the Hang Glider Hill prospect
-
Three key gold anomalies with a North-South trend with results >50ppb Au are located 2.5km to the south of Hang Glider Hill. These highlight the potential for a new mineralised structural setting and are high priority targets for drill testing
-
A further two gold anomalies are located 2-3km south east along strike of Hang Glider Hill and adjacent to the Hang Glider Hill fault which provide further support to this developing trend
-
The new surface gold anomalies generated from early stage exploration enhance the prospectivity of the Hang Glider Hill exploration hub and add five drill ready targets to the portfolio
-
Exploration activity will involve aircore drilling and is now being prioritised and scheduled
Managing Director, Wade Johnson, commented
“These surface sample results are highly encouraging and continue to validate and reinforce the prospectivity of the Hang Glider Hill Exploration
hub. The northerly trending anomalies add a new geological flavour that supports an alternate structural model to enhance the bedrock gold potential of the greater area. Our priority will be to investigate the more prominent gold anomalies by aircore drilling with the aim of defining new bedrock targets for RC drilling”

ASX Announcement, 5 October 2020
ASX Announcement 5 October 2020
Lefroy Exploration Limited (ASX: LEX) (“Lefroy” or “the Company”) is pleased to report on the results from a 3120-hole auger drilling program completed at Eastern Lefroy. The program covered a contiguous package of tenements covering a strike length of 17km from Hang Glider Hill (HGH) gold prospect (refer LEX ASX release 29 November 2019) to the Lucky Strike gold deposit (LEX ASX release 20 May 2020). The area is within the 100% owned non-JV Eastern Lefroy tenement package (Figure 1), part of the greater Lefroy Gold Project (LGP) which is located 50km to the south east of Kalgoorlie
HGH is located in the north west region of the Company’s Lefroy Gold Project (“LGP” or “Project”) and was recognised in 2018 after the discovery of multiple gold nuggets over a 2km trend (Figure 1). It is part of the Eastern Lefroy package of tenements which covers 249km[2] . Tenements are wholly owned by LEX and are not subject to any farm-in agreements

The recent auger geochemical program was designed as a first pass exploration technique to screen a contiguous group of tenements covering 71 square kilometres that straddle the interpreted position of the regional scale Mt Monger fault (Figures 1 & 2). The Company considers areas around the Mt Monger Fault to be prospective for large gold deposits and hence these areas are a major focus for exploration by the Company.

Drill Program
In July 2020 the Company commenced (LEX ASX release 3 August 2020) an early stage auger drilling program as an initial exploration search tool to assess a large area (71km[2] ) adjacent to the interpreted position of the Mt Monger fault (Figures 1 & 2). The program complemented and extended the auger drilling programs completed by the Company during 2018 and 2019 at Hang Glider Hill and HavelockLucky Strike and provide a base surface geochemical coverage over approximately 25km of strike along the Mt Monger Fault (Figure 2). A total of 3120 samples were collected.
The auger drill sampling technique takes a single point sample of a carbonate rich horizon from up to 2m from surface and is effectively a surficial sample. The technique is an effective first pass exploration tool to screen large areas for the surface expression of a shallow bedrock gold system. The majority of the sample points were collected on 50m centres on north east trending lines space 400m apart (Figure 2). A small area of the program was completed on a closer spaced (200m) east west line spacing consistent with an earlier discrete soil sampling program completed by Western Mining Corporation (WMC) in the early 1990’s.

Figure 2 Interpreted geological plan showing detailed location of the completed auger sample points straddling the Mt Monger Fault and the location of Lucky Strike and Hang Glider Hill. Refer to Figure 3 for further detail on the five key auger gold anomalies.
The auger drilling program was completed in early September 2020 and results from all but 300 samples have been received (Table 1). The results from the remaining 300 samples are expected in 2 weeks. The Company pleased to announce the results from the program have been very successful in generating new gold exploration targets for drill testing. The general background of gold anomalism is +10ppb Au over most of the trend. The initial focus is the higher value (+50ppb Au) anomalies. Five new surface gold anomalies (Figure 3) within the Hang Glider Hill exploration hub have been identified.

ASX Announcement, 5 October 2020
ASX Announcement 5 October 2020
Three robust parallel north-south trending gold anomalies (termed C, D &E) that each extend over more than 400-600m in strike length have been outlined south of the Hang Glider Hill prospect (Figure 3). The anomalies are each constrained by results at each auger sample point that exceed 50ppb Au. A peak value of 581ppb Au (0.58g/t Au) comes from anomaly D and is the highest gold result recorded from the program (Table 1).
The Company considers the anomalies C, D and E to be an exciting new development in the Hang Glider Hill area. The northerly trend of the anomalies is oblique to the westerly trend of the mafic and ultramafic stratigraphy. This may represent the surface expression to multiple northerly trending gold mineralised bedrock structures. Prior drilling (RC and diamond) in the area by WMC in the 1990’s targeted the ultramafic stratigraphy for Ni mineralisation but the diamond and RC holes were not analysed for gold. The holes were orientated to the north parallel with the surface gold trends.
A further two anomalies (A&B Figure 3) striking roughly north-west are located approximately 2.5km along strike to the south-east of the Hang Glider Hill prospect where diamond drilling by Lefroy in late 2019 intercepted 6.8m @ 1.86g/t Au from 53.7m. The Hang glider Hill prospect is recognised by a similarly discrete +50ppbAu surface gold anomaly.
Anomaly B has strike length of 600m and varies in width from 150m to 300m. The tenor of gold at anomaly B is considered high with several samples exceeding 75ppb gold in the core of the anomaly. The two new gold anomalies are located proximal to the interpreted position of the Mt Monger and Hang Glider Hill Faults and further strengthen the gold prospectivity along this developing corridor.

Next Steps
The Company considers these new surface gold anomalies to be highly encouraging and as such represent new high priority targets for drill testing in its Eastern Lefroy Project portfolio. The next stage of exploration is being planned which includes:
-
A Program of Works (POW) which has been submitted to the Department of Mines, Industry Regulation and Safety (DMIRS) for an early stage aircore drilling at each of these target areas.
-
• Planning of an early stage reconnaissance wide spaced air core drilling program to prioritise targets for RC drill testing is underway. Drilling is expected to commence in November 2020.
Background-Hang Glider Hill
HGH has been the focus of reconnaissance stage exploration since early 2018 following the discovery of numerous gold nuggets (LEX:ASX 26 June 2018) and preliminary definition of a northwesterly trend extending 2.3km from the original HGH nugget find. The Company considers the gold nuggets to be a surface geochemical anomaly.
In September 2018 the Company completed an early stage auger drilling program as an initial exploration search tool along the trend. A total of 266 samples were collected at 50m centres along 200m spaced east west lines that effectively cover approximately 2000m of strike.
The results of the sampling (ASX: LEX 6 November 2018) defined northern and southern zones of gold anomalism (plus 20ppb Au) around the interpreted position of the Mt Monger Fault. The zones are coincident with the locations of the discovered gold nuggets. The northern anomaly consists of three subparallel trends with a strike of up to 880m. The southern anomaly is centered about Hang Glider hill (a linear topographical feature) and is a coherent anomaly over a 680m strike length.
In November 2018 three angled diamond drill holes were completed (refer LEX ASX release 29 November 2019). Each of the holes intersected a similar geological sequence comprising a shallow oxide zone, and a strongly deformed or sheared zone. These are in contact with a lower, relatively undeformed sequence of biotite altered intermediate volcanic and sedimentary rocks, that includes black shale.
The results from this early stage diamond drilling confirmed gold mineralisation within the sheared and quartz veined rock package in the first hole 19HGDD001. Significant results returned from 19HGDD001 include 6.8m @ 1.86g/t Au from 53.7m and 7.68m @ 0.66g/t Au from 44m (includes VG). The results from the three diamond drill holes have for the first time provided important geological and structural information at Hang Glider Hill has aided refining the geological model at this new gold occurrence.

JORC CODE, 2012 Edition-Table 1 Lefroy Gold Project: Regional Auger Soil Sampling Program – 5 Oct 20 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. |
• Auger sampling Auger samples were collected using a purpose built 6-wheel drive auger rig contracted from Gyro Australia Drill and Survey. The vertical drilling was to depths ranging from 0.5m to 1.5m to collect one representative sample from each hole. The technique and medium collected is considered a surface geochemical sample • Experienced field personnel supplied by the auger company are always present when sampling to ensure the appropriate carbonate rich horizon is collected from each hole • Auger drilling was complete to obtain one sample from each shallow hole from which 200grams was pulverised to produce a 40g charge for fire assay with an ICPMS finish |
| 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). |
• Auger drilling with 3.5inch drill bit with depths ranging from 0.5 to 1.5m |
| Drill sample recovery |

• Recoveries were not assessed as they are not material to the sample collected • Not applicable • Not applicable. On receival at the laboratory all sample weights are measured and reported to the Company |
| 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. |
• Basic surface geology was logged at each site • Sample colour and reaction to hydrochloric acid was recorded and entered to an excel spreadsheet. • Only the specific sampled horizon was logged |
| 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. |
• Not applicable • All samples can be considered a grab or scoop sample to collect enough material to prepare a sample weight of 150-200grams • As the auger sampling is a first pass geochemical sampling program to screen the area it considered appropriate • 3 field duplicates have been taken • Sample size is considered appropriate |
| 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. |
• No geophysical tools, spectrometers or hand held XRF instruments used. • The samples are sent to Bureau Veritas laboratory in Perth where they are weighed, dried pulverised and a 40g sample collected for fire assay and then measured by ICP-MS (lab method FA40_ICPMS) |
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| • 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. |
• The sampling program was conducted using a suite of certified reference materials including duplicates, blanks and standards in the field, and additional lab inserted blanks, standards and replicates • External laboratory checks have not been conducted as they are not deemed material to these results. |
|

• Not applicable • Not applicable |
| Sample security | • The measures taken to ensure sample security. | • The auger contractor despatched all samples as one batch to Bureau Veritas (BV) laboratory in Kalgoorlie. LEX where notified when samples arrived. BV Kalgoorlie then on sent the samples to the BV lab in Perth. The samples are not left unattended. |
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data. |
• No reviews by external parties |
Section 2: REPORTING OF EXPLORATION RESULTS – Lefroy Gold Project- Regional Auger Soil Sampling Program – 5 Oct 20
| 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 50km in a south easterly direction from Kalgoorlie, Western Australia and consists of a contiguous package of tenements covering approximately 621 square kilometres. • The tenements form a contagious package of ground held by Lefroy Exploration and which make up the Lefroy East package which is 100% owned by Lefroy. The tenements are current and in good standing with the Department of Mines, Industry Regulation and Safety (DMIRS) of Western Australia. The tenements are held by Monger Exploration Pty Ltd and wholly owned subsidiary of Lefroy Exploration Limited (LEX). |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Some previous exploration work was completed at Hang Glider Hill by Sovereign Resources NL and documented in an Annual Report to the WA Mines Department for the period 1 October 1992 to 30 September 1993. The Annual report WAMEX file number is A39666. The report documents 6 RC holes being drilled at Hang Glider Hill. • To the South of the Carnilya Hill Nickel mine work was completed by BHP and WMC exploring mostly for Nickel. Sporadic Diamond and RC drilling was conducted on the tenements but the holes were not assayed for gold, much of this exploration occurred duringthe mid-1970-1980s. |
| 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. Archean geology at Hang Glider Hill is referenced from WAMEX report A39666 and field reconnaissance. It consists of a north west trending foliated sequence of ultramafic, chert, metasediments and felsic Volcanic rocks that dip gently the to the south west. Hang Glider Hill forms a prominent topographical feature and interpreted by the Company to be a deformed sequence of metasediment, chert and ultramafic that may represent the position of the regional Mt Monger 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. |
• Analysis of historic WAMEX reports by Sovereign Resources (A 39666) indicated the presence of gold mineralisation identified from surface sampling and RAB drilling of surface anomalies. • Diamond drilling by Lefroy Exploration in 2019 at Hang Glider Hill confirmed gold mineralisation around the hill. More regional AC drilling completed in June 2020 by Lefroy was completed to the North of the Lefroy Gold Project and confirmed North-West trending stratigraphy and weak gold mineralisation. |
| 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. |
• No weighting averaging, maximum and/or minimum grade truncations or cut off grades applied. • Historic and recent LEX drill intercepts previously reported in LEX ASX announcements • No assumptions used for any metal equivalent values. |
| 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’). |
• Not applicable for the surface samples reported. |
| 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 are included in this 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. |
• See body of announcement including figures and table |
| 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. |
• Other relevant exploration data for Hang Glider Hill and its relationship to the nearby gold occurrences have been included in this announcement |
| 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 exploration work has been documented in the body of the report and will drilling. A program of works (POW) for drilling has been approved from the relevant State Government authority. |
