Drilling Extends Shallow Gold Mineralisation at Buccaneer Heap Leach Scoping Study Advances
KEY POINTS
-
17 aircore holes for 1,224m completed at Buccaneer Resource to test for shallow extensions to existing resource
-
Buccaneer Resource is 10Mt @ 1.8g/t Au for 585koz above a 1g/t cut off
-
Scoping study geotechnical and metallurgical diamond drilling is underway to further evaluate a potential low-cost, heap leach processing scenario for the Buccaneer Resource
-
Latest drilling confirms oxide mineralisation at Buccaneer extends 150m to the south of the existing resource – results include the following intersections:
o6m @ 1.4 g/t Au from 12m (BCAC21007)o9m @ 0.5 g/t Au from 21m (BCAC21012)o6m @ 0.7 g/t Au from 9m (BCAC21016) -
An additional 94 holes for 4,091m of aircore drilling completed at the PHD Prospect which is an 11km long soil gold anomaly
-
Previous RC drilling at the PHD Prospect has intersected:
-
8m @ 2.1g/t Au from 56m, including 1m @ 9.4g/t Au from 63m (FM06RC586) (ORD ASX: 28 September 2007)
-
Aircore drilling defined the mineralised structure with coincident gold and arsenic anomalies
Prodigy Gold NL (ASX: PRX) (‘Prodigy Gold’ or the ‘Company’) is pleased to announce results of aircore drilling on the Buccaneer Resource and Hyperion Projects in the Northern Territory (Figure 1 and Figure 3).
At the Buccaneer Resource, a program of 17 aircore holes for 1,124m was completed to test the potential for shallow oxide mineralisation south of the resource and south of the current pit design (Figure 1). Drilling has confirmed that oxide mineralisation at Buccaneer extends a further 150m to the south of the existing resource. A detailed summary of the results is provided below.
Scoping study diamond drilling continues at the Buccaneer Resource. This drilling aims to project geotechnical data for inclusion into a scoping study scenario to treat the 10Mt @ 1.8g/t Au for 585 koz Buccaneer Resource through a low capital heap leach processing facility.

In addition, results are pending for diamond drilling recently completed at the Tregony Deposit, with initial observations of drill intersections highlighting several intervals of veining, including one with visible gold.
Management Commentary
Prodigy Gold Managing Director, Matt Briggs said: “We are very pleased with the initial outcomes from this latest round of drilling, highlighted by confirmation that oxide mineralisation extends for over 150m to the south of the existing Buccaneer Resource. The resource model is currently restricted to the monzogranite intrusion. The conceptual evaluation of the resource under a heap leach processing scenario has highlighted the potential for oxide extensions to the south.
In line with recent aircore drilling, scoping study activity continues to advance at Buccaneer with a diamond drilling program in progress. This drilling will provide both geotechnical data, and samples for metallurgical recovery testwork. Several of the holes are drilling areas outside the known mineralisation and have the potential to add to the resource.
Results of aircore drilling at the PHD Prospect defined the structure consistently along strike, however it did not demonstrate near surface mineralisation of interest. The broader Hyperion Project remains of significant interest to Prodigy Gold and work will now focus on high grade extensions to the Tregony Deposit including the strike extensions under cover to the north. Results are pending from recent drilling at Tregony and we look forward to reporting first assays as soon as possible.”
Buccaneer Oxide Mineralisation Extended to the South
Recently completed aircore drill holes were sampled and assayed over 3m composites. The results include:
-
6m @ 1.4 g/t Au from 12m (BCAC21007)
-
9m @ 0.5 g/t Au from 21m (BCAC21012), and
-
6m @ 0.7 g/t Au from 9m (BCAC21016).
5 of 17 holes drilled intersected significant oxide mineralisation (Appendix 1). The resource model is currently restricted to the monzogranite intrusion.
Pleasingly, these result show that oxide mineralisation extends for over 150m to the south of the current Buccaneer Resource. The oxide extensions to the south have the potential to be included in the resource under a heap leach processing scenario.
Buccaneer Scoping Study Continues
The Company’s focus is on advancing the heap leach processing scenario for the Buccaneer Resource. Scoping study activities are advancing with a diamond drilling program in progress. This drilling will provide both geotechnical data, and samples for metallurgical recovery testwork to optimise the crush size for heap leach extraction of the gold.
Studies undertaken over the last 9 months have evaluated a heap leach processing scenario for the Buccaneer Deposit. When the type of mineralisation is appropriate, heap leaching is a simple, lowcost process that can result in significant savings in capital expenditures and operating costs, which can significantly improve a project's economics. Deep weathering in the Tanami results in softer weathered rocks, and sulphide is often completely oxidised up to 100m below surface.

– Buccaneer Project Background
The Buccaneer Resource is currently estimated to be 10Mt @ 1.8g/t Au for 585koz above a 1g/t cutoff grade[1 ] (Appendix 5). The resource cut-off grade is based on processing at a mill the scale of Northern Star’s Central Tanami JV Processing Plant or a similar mill built on the Twin Bonanza Mineral Lease.
Gold mineralisation is disseminated within a monzogranite intrusion, and typically associated with quartz veins with visible gold often observed in the quartz stockwork veining. Mineralisation extends from near surface to a depth of over 500m and has been defined in several zones over an area of 2,300m by 800m. Mineralisation is often up to 150m thick with intervals of 20-40m wide at 1-5g/t Au[2] . The deposit remains open at depth, and aircore and RAB drilling suggest the potential for further strike extensions.
Studies undertaken so far have evaluated a heap leach processing scenario for the Buccaneer Deposit. When the type of mineralisation is appropriate, heap leaching is a simple, low-cost process that can result in significant savings in capital expenditures and operating costs and can significantly improve a project's economics. Deep weathering in the Tanami results in softer weathered rocks, and sulphide is often completely oxidised up to 100m below surface.

PHD Prospect Recent Aircore Drilling Results
Recent reconnaissance aircore drilling tested the potential for shallow mineralisation associated with a soil anomaly of 11km in length and a “splay” structure of the regional-scale Suplejack Fault Zone (Figure 2). Holes were sampled and assayed using 3m composites, or shorter intervals for visible mineralisation. No significant results (over 0.5g/t Au) were reported.
Results of aircore drilling at the PHD Prospect defined the structure consistently along strike (Figure 3). Future work at the Hyperion Project will focus on high grade extensions to the Tregony Deposit including the strike extensions under cover to the north.

PHD Prospect Background
PHD is an 11km soil gold anomaly within the Hyperion Project, located 30km northwest of the existing 4.93Mt @ 1.95g/t 310koz gold resource[4] and 40km north of Northern Star’s 1.1Moz Groundrush Resource (Figure 2). Shallow RC drilling by previous owner Ord River Resources in 2005 and 2006 defined gold within two zones over 3.5km of strike at PHD. Sampling along strike of the historic anomalism extended the soil gold anomaly over the structure to 11km in length. Airborne magnetic surveying completed in 2019 highlighted the extensions of the structure along strike and the potential for parallel structures. The area of interest is underlain by sequences belonging to the favourable Tanami Group. It is poorly exposed, with the majority of the geology interpreted from regional

Five existing deposits (Figure 2) are known along the Suplejack Fault, the major structural control of the project:
-
Groundrush Deposit (10.5Mt @ 3.3g/t Au for 1.129Moz[5] - 50% Tanami Gold, 50% Northern Star) is located 42km to the south with the same NW trend as PHD.
-
Hyperion Deposit (4.93Mt @ 1.95g/t Au for 310koz above a 0.8g/t cut off - 100% Prodigy Gold) located 27km to the south.
-
Crusade Deposit (1.4Mt @ 2.6g/t Au for 119koz[5] - 50% Tanami Gold, 50% Northern Star) is located 22km to the northeast.
-
Ripcord Deposit (1.1Mt @ 2.5g/t Au for 89koz[5] - 50% Tanami Gold, 50% Northern Star) is located adjacent to the Groundrush Deposit.
-
The Tregony Deposit (~0.64Mt @ 3.02g/t for 62.7koz[6] ounce deposit (JORC 2004), 100% Prodigy Gold) is located 11km to the east. The deposit consists of what appear to be shallow dipping quartz vein arrays within the Killi Killi Formation with some exceptionally high historic gold grades in drilling, including [email protected]/t Au, [email protected]/t Au, and [email protected]/t Au.

|---|---|---|
| Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information |
AC drilling was sampled as 3m composites by spear or scoop, sampling the total reject to produce a 2-3kg representative composite sample. Prodigy Gold samples were submitted to a contract laboratory for crushing and pulverising to produce a 40 g charge for Fire Assay with AAS finish. For all AC holes the final metre of each hole (end‐of-hole) was collected as a single metre multi-element (ME) sample. The ME sample is assayed for gold as described above and is additionally assayed for a suite of 59 different accessory elements (multi-element using the Bureau Veritas MA100/1/2 routine which uses a mixed acid digestion and finished by a combination of ICP-OES and ICP-MS depending on which method provides the best detection limit). The nature of gold mineralisation could be variable and include high grade, high nugget quartz veins, and disseminated sulphide typical of other deposits in the area. Mineralisation has shown a correlation to sulphide and veining in the area in the past. |
|
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
AC drilling was undertaken by Bullion Drilling with an AC drill rig with a |
500cfm/250psi on-board compressor. This rig has a depth capacity of approximately 120m for AC drilling. A 3 ½” aircore bit and hammer were used for the holes. |
||
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed |
Recoveries from drilling were generally 90%-100%, though occasional near surface samples have recoveries of 50%. Anomalous samples reported in the announcement all have acceptable (complete or near complete) sample recovery. Samples were typically dry with minor wet samples near the bottom of hole. Moist or wet samples were not riffle-split into 1m samples, and instead were left open to dry out for potential future analysis. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples |
The cyclone was cleaned after every hole and every 30m or after wet samples to minimise potential for contamination. The scoop/spear used to produce composite samples was cleaned regularly. The riffle splitter was cleaned after each metre for 1m 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. |
There is no relationship between grade and recovery due to the consistently high sample recovery. Aircore drilling is typically designed as a reconnaissance tool to define gold and multi-element anomalies in the regolith. Additional measures were taken for this AC program to potentially use results in future resource estimation or extension. One metre dry samples were riffle split and set aside for possible analyses, where corresponding composite sampling demonstrated anomalous gold results. Sample recovery does not impact identification of anomalies and consequently no detailed analysis has been undertaken to determine a relationship between grade and recovery for this program. With sample recovery >90% bias is unlikely due to preferential loss/gain of fine/coarse material. |
|
| Logging | Whether core and chip samples have been geologically and geo-technically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
Prodigy Gold AC samples were geologically logged at the drill rig by a geologist. Data on lithology, weathering, alteration, mineral content and style of mineralisation, quartz content and style of quartz were collected. Sample rejects are preserved in green bags for re-logging by the competent person detailed on this report where anomalous grades were encountered in preliminary composite sampling. All anomalous composite samples were reviewed by the competent person on this report. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. |
Logging is both qualitative and quantitative. Lithological factors, such as the degree of weathering and strength of alteration are logged in a qualitative fashion. The presence of quartz veining, and minerals of economic importance are logged in a quantitative manner. Logging records interpreted lithology, mineralogy, mineralisation, weathering, colour and other features of the samples. EOH samples are wet‐sieved and stored in a chip tray. Chip trays are photographed for posterity. Remaining sample materials are preserved and stored in open green bags for any moisture to evaporate, until such time as it is determined the material should be rehabilitated. |

All holes were logged in full by Prodigy Gold geologists. |

If core, whether cut or sawn and whether quarter, half or all core taken. |
No core was collected |
| If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. |
1m samples were collected from a cyclone into green plastic bags. Green bags were additionally sampled using a riffle splitter utilizing the entirety of the sample reject contained in each green bag. The entire 1m sample was riffle split to create a 2-3kg representative sample of the 1m return. Drilling was sampled as 3m composites by spear/scoop sampling the total reject to produce a 2-3kg composite sample. At the end of hole (EOH) a 1m 2-3kg spear/scoop sample was collected for ME analyses. Samples were typically dry with minor wet samples. Wet and dry samples were not mixed in the composites. Wet samples were not riffle split. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
All samples have been analysed for gold by Bureau Veritas in Adelaide. Samples were dried and the whole sample pulverised to 85% passing 75µm, and a sub sample of approximately 200g is retained for Fire Assay which is considered appropriate for the material and mineralisation and is industry standard for this type of sample. |
|
| Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. |
The cyclone is routinely cleaned and samples visually inspected for contamination. Drilling of wet samples is avoided and the nature of the sample is recorded. 3m composite samples are aimed for anomaly detection with an expectation that the 1m riffle-split (dry) samples to be subsequently analysed and used for additional resource extension where appropriate. Blanks and standards were inserted in sequence at a frequency of approximately 1 in 20 for initial 3m composite analyses. Similar QAQC procedures will be used for any subsequent 1m riffle split sample submissions. QAQC results are screened by the database geologist prior to final review by the competent person on this release. Laboratory internal QAQC was conducted at Bureau Veritas, as per industry standard. |
|
| 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. |
3m composites are taken from the 1m sample bags. Samples are collected to weigh less than 3kg to ensure total preparation in the pulverisation stage. 1m riffle split samples were taken on all dry samples in the program. The multi-tier riffle splitter is cleaned with compressed air after each sample. The entirety of the sample contained in the green bag is processed through the riffle splitter, which splits a representative 2-3 kg sample directly into a calico bag, with the remainder of the sample reject deposited into a bucket and subsequently returned into the original green bag. The bucket used to contain the sample reject below the riffle splitter is routinely cleaned at the same time as was the riffle splitter after each sample. !m sample results will be compared to 3m composite results. Field duplicates are not produced for composite samples. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
Sample sizes are considered appropriate to give an indication of mineralisation given the particle size and preference to keep the sample weight below 3kg to ensure the requisite grind size in a LM5 sample mill. Anomalous intervals reported are all in oxide. Gold grains are not expected to be coarse. |

|
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
A blank or standard was inserted approximately every 20 samples. For drill samples, blank material was supplied by the assaying laboratory. Two certified standards, acquired from GeoStats Pty. Ltd., with different gold grade and lithology were used. QAQC results are reviewed on a batch by batch basis and at the completion of the program. |

Primary data was collected into an Excel spreadsheet and the drilling data was imported in the Maxwell Data Schema (MDS) version 4.5.1. The interface to the MDS used is DataShed version 4.5 and SQL 2008 R2 (the MDS is compatible with SQL 2008-2012 – most recent industry versions used). This interface integrates with LogChief and QAQC Reporter 2.2, as the primary choice of data capture and assay quality control software. DataShed is a system that captures data and metadata from various sources, storing the information to preserve the value of the data and increasing the value through integration with GIS systems. Security is set through both SQL and the DataShed configuration software. Prodigy Gold has an external consultant database administrator with expertise in programming and SQL database administration. Access to the database by the geoscience staff is controlled through security groups where they can export and import data with the interface providing full audit trails. Assay data is provided in MaxGEO format from the laboratories and imported by the database administrator. The database assay management system records all metadata within the MDS and this interface provides full audit trails to meet industry best practice. |

The Buccaneer Resource was originally discovered by North Flinders Mines in the late 1990s. Newmont Asia Pacific Ltd. (Newmont) acquired the property and continued active exploration through 2006. Newmont/North Flinders drilled a total of 830 holes into the prospect – 103 aircore, 669 RAB, 48 RC, and 10 RC with diamond extensions – totalling 51,082m and provided the foundation of understanding of the Buccaneer Deposit. The Buccaneer Project has had a considerable amount of drilling completed by previous explorers, which has defined the existing resource. The sampling has been carried out using a combination of aircore (AC), reverse circulation (RC) and diamond drilling. Significant historic RAB drilling covers the area and was used in developing the lithological and mineralisation interpretation. However, this data was not used in the estimate and is not detailed here. 124 AC, 163 RC, 8 RC(D) with diamond tails and 5 diamond holes were drilled between 1993 and 2015 and was undertaken by several different companies: 1993– 1996 – RAB and DDH drilling by North Flinders Mines 1997 – 1999 – RC and RAB drilling by North Flinders Mines 2004 – AC, RAB and RC drilling by North Flinders Mines 2010 – 2015 - AC, RC, RCD and DD byABM Resources |
| Geology | Deposit type, geological setting and style of mineralisation. |
Gold mineralisation is disseminated within a monzogranite intrusion, and typically associated with quartz veins. Visible gold is seen in the quartz stockwork veining. Mineralisation extends from near-surface to a depth of over 500m and has been defined in several zones over an area of 2,200m by 800m. Mineralisation within the main body of the monzogranite has been recognised to have a moderate north-easterly dip. Horizontal oxide mineralisation is observed overlying the Monzogranite intrusion. |

| 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. |
All relevant historical drill hole information has been previously reported |
through open file reporting by previous explorers. |
||
Summaries of all material drill holes from previous Prodigy Gold drilling |
||
| are available within the Company’s ASX releases. | ||
| 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 |
No exploration information material to the announcement has been |
|
excluded. Subsequent to the completion of the 2017 resource estimate, |
||
approximately 35,000 geological logging records from drilling completed |
||
in 2012-2016 were identified as missing from the Company’s database. |
||
| These have been loaded into the database and are being reviewed to | ||
| assess the potential for a resource estimate with enhanced geological | ||
| input. | ||
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. |
Prodigy Gold reports length weighted intervals with a nominal 0.5g/t gold lower cut-off. As geological context is understood in exploration data highlights may be reported in the context of the full program. No upper cut-offs have been applied as intersections. |
| 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. |
Summaries of all material drill holes and approach to intersection generation are available within the Company’s ASX releases. All results are shown on maps. Highlight holes are reported individually. It should not be assumed all results are represented labelled on diagrams. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalents are being reported. |
|
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the 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 (e.g. ‘down hole length, true width not known’). |
The majority of drilling is RC, and thus the exact geometry of the |
| mineralisation with respect to drill angle cannot be determined. From the | ||
limited diamond drilling, the Company identified stockwork veining at |
||
various orientations. The overall trend of the fresh mineralisation has a |
||
moderate north-easterly dip. Subsequently, drill holes are angled at 60 |
||
degrees to drill as close to orthogonal to mineralisation as possible. |
||
Intercepts reported are down hole length, 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. |
Refer to Figures and Tables in the body of the text. |
| 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. |
The Company reports all assays as they are finalised by the laboratory. All |
material assays received to date from Prodigy Gold’s drilling above reflect |
||
intervals of >0.5g/t Au or where geologically significant. Intervals are |
||
geologically significant where sulphide and/or veining is logged and |
||
| samples are above 0.1g/t Au. | ||
| 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. |
Appropriate data is provided in the announcement. Multi-element geochemistry and spectral logging studies have been completed on the deposit. These are used to influence the interpretation of the regolith profile and host rock lithology. Metallurgical test work has previously been published on 17thAugust 2015. No deleterious elements are noted. Subsequent to the completion of the 2017 resource estimate, approximately 35,000 geological logging records from drilling completed in 2012-2016 were identified as missing from the Company’s database. These have been loaded into the database and are being reviewed to assess the potential for updating the resource estimate with enhanced geological input. |

Appendix 6: JORC Table 1 PHD Aircore Drilling
SECTION 1: SAMPLING TECHNIQUES AND DATA
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. |
Vertical aircore (AC) drilling of 94 AC holes for 4,091 metres. Drilling was completed along the 11km strike of soil gold anomalism. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used |
The full length of each hole was sampled. Sampling was carried out under Prodigy Gold’s protocols and QAQC procedures. Bag sequence, sample moisture, and estimated sample recovery is checked regularly and recorded by field staff and supervising geologist against a dedicated sample register. Laboratory QAQC was also conducted. |
|
| Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information |
AC drilling was sampled as 1m samples, or 3m composites by spear sampling the total reject to produce a 2-3kg composite sample. Holes are drilled vertically aiming to identify lateral dispersion of gold in oxide, or pathfinder elements to allow the subsequent targeting of infill drilling. Mineralisation if directly intersecting is likely to be moderately dipping quartz veins within a fault or shear zone, or sub horizontal supergene enrichment. Supergene mineralisation is expected to have a relative homogenous distribution of gold. Mineralisation intersected in rock is likely to be coarser and higher in nugget. |
|
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
AC drilling was undertaken by Bullion Drilling with an AC drill rig with a 500cfm/250psi on-board compressor. This rig has a depth capacity of approximately 120m for AC drilling. A 3 ½” aircore bit and hammer were used for the holes. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed |
Recoveries from drilling were generally 90%-100%, though occasional near surface samples have recoveries of 50%. Samples were typically dry with minor wet samples. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples |
Drillers used appropriate measures to minimise down-hole and/or cross hole contamination in AC drilling. The cyclone and buckets were cleaned after every hole and every 30m or after wet samples to minimise potential for contamination. |
|
| 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. |
Aircore drilling is designed as a reconnaissance tool to define gold and multi-element anomalies in the regolith. Sample recovery does not impact identification of anomalies and consequently no detailed analysis has been undertaken to determine a relationship between grade and recovery for this program. With sample recovery >90% bias is unlikely due to preferential loss/gain of fine/coarse material. |
|
| Logging | Whether core and chip samples have been geologically and geo-technically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
Prodigy Gold AC samples were geologically logged at the drill rig by a geologist. Data on lithology, weathering, alteration, ore mineral content and style of mineralisation, quartz content and style of quartz were collected. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. |
Logging is qualitative in nature and records interpreted lithology, mineralogy, mineralisation, weathering, colour and other features of the samples. EOH samples are wet‐sieved and stored in a chip tray. |
|
| The total length and percentage of the relevant intersections logged |
All holes were logged in full by Prodigy Gold geologists. |

| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
No core was collected. |
| If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. |
1m samples were collected from a cyclone into a plastic bucket and then laid out on the ground in rows of 10 or 20. Drilling was sampled as 3m composites by spear sampling the total reject to produce a 2-3kg composite sample. At the end of hole (EOH) a 1m 2-3kg spear sample was collected. Recoveries from drilling were generally 90%-100%, though occasional near surface samples have recoveries of 50%. Samples were typically dry with minor wet samples. Wet and dry samples were not mixed in the composites. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
All samples have been analysed for gold by Bureau Veritas in Adelaide. Samples were dried and the whole sample pulverised to 85% passing 75µm, and a sub sample of approximately 200g is retained for Fire Assay which is considered appropriate for the material and mineralisation and is industry standard for this type of sample. |
|
| Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. |
The cyclone is routinely cleaned and samples visually inspected for contamination. Drilling of wet samples is avoided and the nature of the sample is recorded. Reconnaissance drilling is aimed for anomaly detection with an expectation of significant additional drilling prior to the declaration of a resource. Blanks and standards were inserted in sequence at a frequency of approximately 1 in 20. QAQC results are screened by the database geologist prior to final review by the project geologist. |
|
| 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. |
3m composites are taken from the 1m sample piles using a spear which penetrates across the full sample. The pile is sampled in multiple slices from different angles ensuring a representative sample is taken. Samples are collected to weigh less than 3kg to ensure total preparation in the pulverisation stage. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
Sample sizes are considered appropriate to give an indication of mineralisation given the particle size and preference to keep the sample weight below 3kg to ensure the requisite grind size in a LM5 sample mill. |
|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the | Prodigy Gold use a lead collection fire assay using a 40g sample charge. For |
| assaying and laboratory procedures used and whether the technique is considered partial or total. |
low detection, this is read by ICP-AES, which is an inductively coupled plasma atomic emission spectroscopy technique, with a lower detection limit of 0.001ppm Au and an upper limit of 1,000ppm Au which is considered appropriate for the material and mineralisation and is industry standard for this type of sample. |
|
| 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. |
ME results are only used for indicative analysis of litho-geochemistry and alteration and to aid logging and subsequent interpretation. 4 acid digest data on the ME and end of hole samples are used to assist in litho- geochemical determination. |
|
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
A blank or standard was inserted approximately every 20 samples. For drill samples, blank material was supplied by the assaying laboratory. Two certified standards, acquired from GeoStats Pty. Ltd., with different gold grade and lithology were used. QAQC results are reviewed on a batch by batch basis and at the completion of the program. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
Significant intersections were calculated independently by both the project geologist and database administrator. |
| The use of twinned holes. | No dedicated twin holes have been drilled as this is not considered appropriate for early stage reconnaissance drilling. |

Primary data was collected into an Excel spreadsheet and the drilling data was imported in the Maxwell Data Schema (MDS) version 4.5.1. The interface to the MDS used is DataShed version 4.5 and SQL 2008 R2 (the MDS is compatible with SQL 2008-2012 – most recent industry versions used). This interface integrates with LogChief and QAQC Reporter 2.2, as the primary choice of data capture and assay quality control software. DataShed is a system that captures data and metadata from various sources, storing the information to preserve the value of the data and increasing the value through integration with GIS systems.

| Whether sample compositing has been applied. | AC drill samples from this program were composited from 1m piles to 3m composites samples. |
|
| 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. |
All holes were drilled vertically. As this is early stage of drilling the orientation of the drilling to mineralisation is not known. |
| 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. |
No orientation based sampling bias has been identified in this data. Holes |
|
are reconnaissance in approach and are drilled vertically. |
||
| Sample security | The measures taken to ensure sample security. | Samples were transported from the rig to the field camp by Prodigy Gold personnel, where they were loaded onto a Toll Express truck and taken to Bureau Veritas Laboratories secure preparation facility in Adelaide. Prodigy Gold personnel have no contact with the samples once they have been picked up for transport. Tracking sheets have been set up to track the progress of the samples. The preparation facilities use the laboratory’s standard chain of custody procedure. Details regarding sample security of drilling prior to 2010 are not readily available. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
Prodigy Gold conducted a Lab Visit to Bureau Veritas laboratory facilities in |

|---|---|---|
| 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 |
No information or data material to the reporting of the current program |
|
has been excluded. Historic information is not fully reported for reasons |
||
of conciseness. |
||
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. |
Prodigy Gold has reported length weighted intervals with a nominal 100ppb gold lower cut-off. As geological context is understood in exploration data highlights may be reported in the context of the full program. No upper cut-offs have been applied. |
| 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. |
Summaries of all material drill holes and approach to intersection generation are available within the Company’s ASX releases. All results are shown on maps. Highlight holes are reported individually. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalent values are used. |
|
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the | From surface mapping and previous drilling in the district, host lithologies |
| 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 (e.g. ‘down hole length, true width not known’). |
and mineralisation are most commonly steeply dipping (between 60 and | |
80 degrees). |
||
| 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. |
Refer to Figures and Tables in the body of the text. As the AC drilling is at a reconnaissance stage, and broad drill spacing, cross sections are not yet included in the 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. |
All material assays received to date from Prodigy Gold’s drilling above a |
0.1g/t Au gold lower cut-off have been reported together with reference |
||
to historical drilling results of significance. |
||
| 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. |
Multi-element geochemistry of current downhole samples and historic spoils has been compiled over the target area. Results are used to influence the interpretation of the regolith profile and host rock lithology. |
