Reynolds Range Exploration Update: First Diamond Drill Hole Complete at Scimitar Au-Cu Target
KEY POINTS
-
400m diamond drill hole (SCDD2001) has been completed at the Scimitar Target to confirm a base metal association with 2km long southwest dipping MLEM conductor
-
A second 500m diamond hole is planned to test the stronger zone of the EM conductor, 600m to the north of SCDD2001, at the cessation of wet season
-
Surface sampling has highlighted strong gold and base metal anomalism, coincident with MLEM modelled conductor identified at Scimitar
-
Anomalism extends for 3km including a Au-Cu dominant trend extending for 1.5km
-
Ag-Zn dominant trend parallel to EM conductor for 1.8km
-
Scimitar is along trend from historic Reward Copper Deposit which averaged 11% Copper
-
Scimitar is the first of several highly prospective targets to be tested within the Reynolds Range Project – previous RC drilling within the project area has returned up to 17m @ 3.93g/t Au 26m @ 2.73g/t Au (ASX 18 Jan 2010)
Prodigy Gold NL (ASX: PRX) (‘Prodigy Gold’ or the ‘Company’) is pleased to advise that it has completed a 400m diamond drill hole (Figure 1) at the Scimitar Target within the Company’s Reynolds Range Project in the Northern Territory.
Previously reported high-grade sampling results (see ASX announcement dated 24 November 2020) confirmed the presence of a strong gold and base metal anomalism at the Scimitar Target, and Prodigy is now working to identify the source of this anomaly.
Drill hole (SCDD2001), co-funded by the Northern Territory Geological Survey (‘NTGS’) as part of the Resourcing the Territory initiative, was designed to confirm a base metal association with 2km long southwest dipping MLEM conductor, located in the centre of the geochemical anomaly (ASX 16 November 2020).
A second 500m diamond drill hole has been designed to intersect a deeper, higher conductance zone.

Drill Hole SCDD2001 Summary
SCDD2001 intersected a package of interbedded sandstone and siltstone with minor black shales and diorite intrusions (Figure 4). Sulphides including pyrite, pyrrhotite, sphalerite, galena and minor chalcopyrite were associated with quartz veining in deformed black shales over several intervals. The strongest part of the conductor is modelled to start 240m vertically below surface. Minor sulphide has been intersected in the drillhole at the target depth of 350m down hole.
The sphalerite and galena (Figure 3) in the black shales intersected in SCDD2001 may be the source of the surface Zn and Pb anomaly. Downhole EM (DHEM) will be completed at the commencement of the 2021 field season. This will confirm whether the sulphidic shales identified in the drilling are the cause of the airborne and moving loop EM anomalies. The stronger zone of EM conductor, 600m to the north of SCDD2001, remains untested. A second 500m diamond hole is planned to drill the conductor depending on assay results and the DHEM survey.
The source of the high-grade Cu and Au soil and rock chip anomaly (1km long) has not been confirmed by this hole. Prodigy is currently planning RC drilling closer to the Cu and Au surface anomalies.
Scimitar is along trend from the historic Reward Cu Deposit, which averaged 11% Cu and is the first of several targets to be tested at Reynolds Range over the coming months.

Management Commentary
Prodigy Gold Managing Director, Matt Briggs said: “We are pleased to report the completion of the first of two diamond holes planned for the Scimitar Cu-Au Target. The second hole, which is planned to be drilled 600m to the north of SCDD2001, will test the strongest zone of the EM conductor and we expect to complete this hole at the cessation of the wet season.

This initial round of drilling is the first phase of our broader exploration strategy for Reynolds Range which aims to test several highly prospective targets with favourable structural indicators for hosting gold and base metal mineralisation. Many of these targets are associated with historical exploration and mine workings yet have had little exposure to any form of modern exploration which provides an excellent opportunity for Prodigy.
I look forward to providing updates on the results of diamond drilling from Scimitar and on our plans to drill the Falchion and Sabre Targets in the near-term.”
Next Steps
Assays will be received and evaluated for SCDD2001 in January and down-hole EM logging will be conducted at the commencement of the field season in 2021. Field work will continue and drilling is planned to test other priority targets at Reynolds Range including the follow-up drilling at Scimitar, the Reward Cu-Au EM Target, the Falchion Target and the Sabre Au Prospect.
Reynolds Range Exploration Overview
The Scimitar Target is one of a number of Au and Cu targets being advanced by the company on the Reynolds Range Project. Previous exploration at Reynolds Range has identified significant gold in drilling with RC results including 17m @ 3.93g/t Au 26m @ 2.73g/t Au (ASX 18 Jan 2010).
In October 2020 the company undertook a moving loop electromagnetic (MLEM) survey over the Scimitar Target. Detailed mapping identified evidence of Cu mineralisation at surface within a 3km long geochemical anomaly.
Of 127 samples collected in late 2020, 39 returned significant anomalism of up to 7.5g/t Au, 1,950g/t Ag, 19.3% Cu, and 21.3% Pb (Figure 2) (ASX 24 November 2020). Within the larger 3km long geochemical anomaly, separate Cu-Au and Ag-Pb zonation is observed. Elevated Cu-Au rock chips are exposed for 1.5km in a north-south trend, where east-west structures are exposed on a topographic high.

Reynolds Range Project Background
The project area is accessed from the Stuart Highway and are between 90 and 250km north of Alice Springs. Targets between 20km and 120km off the NT highway, railway line (Ghan) and the NT gas pipeline. These projects have excellent access and land ownership is a combination of pastoral lease and aboriginal land (ALRA). Prodigy Gold has negotiated access and permits to the land.

Figure 5 - Scimitar Target Area with diamond drill rig in the middle ground.
Mineralisation was first identified in the area in the early 1900s with over 500 different mineral occurrences and old mines identified including extensive tin fields at Coniston (Reynolds Range); old copper workings, silver-lead-zinc mines and numerous gold occurrences.
A series of predominantly E-W to NW-SE striking shear zones transect the project areas. These shear zones, in places, have retrograded the amphibolite facies country rock to greenschist facies. Gold mineralisation consist of sheared and sheeted-quartz vein deposits with the potential for economic deposits. Discoveries such include mineralisation at the:
Sabre Prospect 17m @ 3.93g/t Au[1] , 26m @ 2.73g/t Au[2] , and 24m @ 2.59g/t Au[3] and
Falchion Prospect 12m @ 3.76g/t Au[3] , 16m @ 3.67g/t Au[3]
Several occurrences have been identified that include high-grade copper and silver (+- gold) associated with distal lead-zinc occurrences. The Jervois deposits (located further east in the Arunta), the Bumblebee discovery (located near Kintore in the South Arunta / Warumpi Margin) and the Tennant Creek deposits (located to the north in the Tennant Creek inlier) are described as iron oxide copper-gold targets. The rocks at Reynolds Range are believed to have similar potential.
Notable Reynolds Range Targets
Falchion Target - Old gold workings associated with Lander shear zone. Evidence of base metals including tin and antimony in the area. Known gold-antimony mineralisation including results of:
-
12m @ 3.76g/t Au[3]
-
16m @ 3.67g/t Au[4]
RC and diamond drilling have been completed on a single section, however gold mineralisation extends for over 400m in RAB drilling.

PHD Exploration
PHD is a 9km soil Au anomaly on Hyperion Project, 30km northwest of the existing 310koz gold deposit. Shallow RC drilling by Ord River Resources in 2005 defined gold in RC drilling within two zones over 3.5km of strike at the PHD Prospect. Previous soil anomalism associated with this structure has now been shown to extend for over 9 km. Airborne magnetic surveying completed in 2019 highlights the extensions of the structure along strike and the potential for parallel structures.
During November 2020 sampling and mapping was undertaken in preparation for the planned aircore drilling program. 147 samples were collected on an irregular 600x50m spacing infilling areas not

previously sampled along strike of previous RC drilling. Results have returned and the soil sampling supports the continuity of the anomaly interpreted from airborne magnetics data. (Figure 6). Aircore drilling is planned to commence at the beginning of the 2021 field season at a 500m x 100m spacing. The results of aircore drilling and structural interpretation, will be used to design subsequent RC drilling.

Bluehart exploration update
The Bluehart target is located 53km along strike of the 14Moz Callie Gold Mine and is associated with a 1,000m long high-grade soil and rock chip gold anomaly (Figure 7). Bluehart is associated with a northwest trending splay off the Trans-Tanami Fault Zone, similar to Callie. This northwest splay is coincident with soil and rockchip gold anomalism. Similar to the Callie deposit, sinistral shearing and east-west aligned anticlines are present within the three target areas at Bluehart with graphitic reduced sediments mapped in outcrop.
Aircore drilling, comprising 57 holes for 1,869m, was completed in the second half of 2020, testing three targets at the Bluehart Prospect. Low level gold results were returned last quarter with no significant assays being returned from the aircore program (Figure 8). The thickness of Dead Bullock Formation, the target stratigraphic horizon, is thinned in the area limiting the potential for gold deposits of the scale targeted by the company.

|---|---|---|
| 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. |
The sampling has been carried out by vertical Aircore (AC) drilling. 57 vertical AC holes for 1,869 metres have been drilled at the Bluehart Prospect. Sampling is undertaken using standard industry practices. |

geologist against a dedicated sample register. Laboratory QAQC was also conducted. See further details below. |
|
| 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 sampling the total reject to produce a 2-3kg 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 finish by a combination of ICP-OES and ICP-MS depending on which method provides the best detection limit. |
|
| 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 multielement 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. |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| 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 |

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. |

| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
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 Bluehart target is located in the Bluebush area and was first | ||

| NFM and Newmont Asia Pacific subsequently all conducted exploratory | ||
| work on the project with the last recorded drilling (prior to Prodigy Gold) | ||
| completed in 2007. Previous exploration work provided the foundation on | ||

Bluebush The Bluehart Target area is located 50 km northwest of the Callie Gold Mine and 10 km southwest of the Wild Turkey and Jim’s Find deposits. The structural framework at Bluehart is related to folds and splays associated with the Trans Tanami Shear and is structurally similar to other areas with significant gold mineralisation in the Tanami, such as the Callie, Groundrush, and Hurricane deposits (Huston et al., 2007). The area is largely covered by transported sandplains. Prospective reduced graphitic horizons and mylonitic gneiss of the Dead Bullock Formation have been mapped in the target area amongst a suit of deformed igneous intrusive rocks. Mineralisation is expected to be Callie-style orogenic gold. |

|---|---|---|
| Data aggregation methods |
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. |
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 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’). |
From surface mapping and previous drilling in the district, host lithologies |
| and mineralisation are most commonly steeply dipping (between 60 and | ||
80 degrees). Where sufficient outcrop exists to inform planning, drill holes |
||
are angled so as to drill as close to perpendicular to mineralisation as |
||
possible. |
||
| 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. |
| Further work | The nature and scale of planned further work (e.g. 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 |
Further work includes: |
- No further drilling is planned at the Bluehart Prospect area. |
