Reynolds Range Exploration Update: Scimitar Diamond Drill hole Results
KEY POINTS
-
400m diamond drill hole (SCDD2001) completed at the Scimitar Target to confirm a base metal association with a 2km long southwest dipping MLEM conductor
-
Result of assays correlate with sulphidic sediments observed in the hole
-
Downhole EM to be conducted at the commencement of the field season
-
Surface sampling has highlighted strong gold and base metal anomalism, coincident with the 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 extending for 1.8km
-
Scimitar is along trend from the historic Reward Copper Deposit which averaged 11% Cu
-
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 and 26m @ 2.73g/t Au (ASX 18 Jan 2010)
Prodigy Gold NL (ASX: PRX) (‘Prodigy Gold’ or the ‘Company’) is pleased to advise it has received results of a 400m diamond drill hole (Figure 1) completed at the Scimitar Target within the Company’s Reynolds Range Project in the Northern Territory.
In November 2020, Prodigy Gold confirmed the presence of a strong gold and base metal anomaly at the Scimitar Target (ASX 24 November 2020), and the two planned diamond drill holes have been design to assist with identifying the source of this anomaly.
The first 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 a 2km long southwest dipping MLEM conductor, located in the centre of the geochemical anomaly (ASX 16 November 2020).

Management Commentary
Prodigy Gold Managing Director, Matt Briggs said: “Results from the first diamond drill hole at Scimitar confirm that sulphidic sediments are the likely cause of the EM conductor which will be confirmed in DHEM during the 2021 field season. The sediments contain Ag-Pb-Zn explaining the surface anomalism in these metals.
“The bedrock source of strong Cu-Au anomalism of up to 7.5g/t Au and 19.3% Cu (ASX 24 November 2020), 1km to the east, remains unexplained and will be the focus of our 2021 exploration at Scimitar. The Cu-Au anomaly associated with malachite and quartz veining extends for 1.5km and remains untested by bedrock drilling. RAB and RC drilling is already permitted for this target.
“Reynolds Range is a province scale project with several highly prospective targets. Further drilling is planned to test a number of targets, along with large scale soil anomalies on our North Arunta and Tanami Projects.”
Drill Hole SCDD2001 Summary
Diamond drill hole 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 are associated with quartz veining in deformed black shales (Figure 3) over several intervals.
Notable results from the assaying of drill hole SCDD2001 correlate with sulphidic sediments (Figure 3) intersected in the hole. These sediments occur from 286-302.2m downhole near to the 350m target depth, based on the modelled EM plate conductor (Figure 4). Best results for the interval are summarised in Appendix 2. These include narrow intervals of elevated Ag-Pb-Zn.
Next Steps
The sulphidic sediments in SCDD2001 are likely to 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 the EM conductor, 600m to the north of SCDD2001, remains untested. A second 500m diamond hole is planned to drill the conductor depending on the results of the DHEM survey. If DHEM confirms the sulphidic sediments are the source of the conductor the second hole is unlikely to be drilled.
The source of the 1.5km long high-grade Cu and Au soil and rock chip anomaly (Figure 3) has not been identified by this hole. Prodigy Gold is currently planning RC drilling closer to the Cu and Au surface anomaly.
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.
Downhole 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 and 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 is between 90 and 250km north of Alice Springs. Targets are located 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 include mineralisation at the:
Sabre Prospect 17m @ 3.93g/t Au[1] , 26m @ 2.73g/t Au[2] , and 24m @ 2.59g/t Au[1] and Falchion Target 12m @ 3.76g/t Au[2] and 16m @ 3.67g/t Au[2]
Several occurrences have been identified that include high-grade copper and silver (+- gold) associated with distal lead-zinc. 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 the Lander shear zone. Evidence of base metals including tin and antimony can be found in the area.
Known gold-antimony mineralisation including results of:
-
12m @ 3.76g/t Au[2]
-
16m @ 3.67g/t Au[2]
RC and diamond drilling have been completed on a single section, however gold mineralisation extends for over 400m in RAB drilling.
Sabre Prospect - Shallow gold workings associated with the Lander shear zone. Evidence of base metals including tin and antimony can be found in the area.

|---|---|---|
| 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. |
Prodigy Gold has used a Silver City Drilling diamond drill rig. For SCDD2001, diamond core was collected from surface to end of hole. This is HQ hole diameter from surface to end of hole. Upon completion of orientating and geological logging diamond core was cut lengthways, producing a nominal 2kg sample (minimum 0.3 metres, maximum 1.3 metres, generally 1 metre). As hole SCDD2001 was co- funded by the NTGS the remaining half was transferred to the NT Geological Survey core facilities as required by the co-funding agreement. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used |
SCDD2001 was selectively sampled based on observations of structural fabric, alteration minerals or veining. Sampling was carried out under Prodigy Gold’s protocols and QAQC procedures as per industry standard practice. 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 |
The nature of gold and base metal mineralisation could be variable and include high grade, high nugget quartz veins, massive sulphide and disseminated sulphide typical of other deposits in the area. The orientation of mineralisation is not yet confirmed. The hole was selectively sampled via methods typically used on sulphide-related deposits at this stage of drilling as detailed above and below. Mineralisation shows a correlation to sulphide and veining, in particular pyrrhotite, pyrite, galena, sphalerite, and chalcopyrite and quartz sulphide veining. No coarse gold is observed and standard industry work is completed. |

|
| Drill sample recovery |

Diamond core is also logged for structure. The core is retained if further mineral resource work is warranted. |
|
| 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 aquantitative manner. |

If core, whether cut or sawn and whether quarter, half or all core taken. |
Diamond core was cut by a brick core saw. Half core was taken for analysis, and the remaining half submitted to the NTGS core library as a condition of co-funding. Blank material was sourced from Bureau Veritas. Two certified standards acquired from GeoStats Pty. Ltd., with different gold grade and lithology, were also used. Upon receipt by the laboratory samples were logged, weighed, and dried if wet. Samples were then crushed to 2mm (70% pass), then split using a riffle splitter, with 250g crushed to 75 µm (85% pass). 40g charges were then fire assayed. |
| If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. |
Samples are core. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
All samples have been analysed for gold and base metals by Bureau Veritas in Adelaide. Samples were dried and the whole sample pulverised to 85% passing 75 µm, and a sub sample of approximately 200g is retained for Fire Assay which is considered appropriate for the material and mineralisation and is industrystandard for this type of sample. |
|
| Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. |
At the laboratory, regular repeat and Lab Check samples are assayed. |

This interface integrates with QAQC Reporter 2.2, as the primary choice of 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 industrybestpractice. |

| the Stafford Gold Zone with a strike length of over 20km and 10 individual prospects with target area in excess of 80km2. Sabre and Falchion were targeted by Prodigy Gold for follow-up and drilling by Prodigy Gold at Sabre intersected 35m @ 2.02g/t Au including 17m @ 3.93g/t Au3. Further reconnaissance work at Stafford Gold Zone also revealed high grade copper and silver rock chip samples from the Reward Deposit (~9km SE of Sabre) with 20.3% Cu and 271g/t Ag near a downdip EM conductor identified by an airborne electromagnetic survey in 2012. A rock sample grading 1.79g/t Au was also returned from the Pine Hill Prospect (~3.5km SE of Reward). Shortly after this work was completed in the June 2010 quarter, the drill rig was shifted to Prodigy Gold’s Twin Bonanza Project, which incorporates the Old Pirate and Buccaneer Deposits where Prodigy Gold’s focus remained until the restructure to Prodigy Gold under the current management. Refer to ASX 29 November 2013 and 3 February 2014 for details of these results. At the Scimitar Target 305 post and vacuum holes have been drilled previously on a 500x50m grid. The maximum depth drilled is 15m and average depth is 5m. 1991-1992 Poseidon Gold obtained 2 rock chip samples from the Lander Cu prospect. These were from a pelitic unit and a quartz/chlorite breccia with malachite (Price, 1992). 1992-1993 regional lag sampling at 250m intervals by Poseidon Gold defined an area 3km x 2km with anomalous base metals (>80ppm As, >100ppm Pb) and a number of isolated elevated gold values over the Scimitar prospect. 2 rock chip samples and 44 LAG samples were obtained over Scimitar from a 21 rock chip and 1,211 LAG sample program. Maximum values were over Scimitar were 830ppm Zn, 350ppm Pb, and 75ppm Cu. (Price & Price, 1993). 1993-1994 Normandy Exploration and Normandy Poseidon group completed 61 3.6m vertical RAB holes over Scimitar targeting Sb and Au anomalies from a larger 195 hole program totalling 705m. Hole ID’s were RRAB110-RRAB304. Maximum assays returned were 420ppm Cu, 250ppm Zn and 90ppm Pb. Rocks identified included mudstone and siltstone (some carbonaceous) and immature sandstones and greywackes, basalt-dolerite, and common chlorite alteration and moderate quartz veining. (Price, 1994). 1994-1995 Poseidon Gold drilled 100 POST RAB holes averaging 3.6m at 50m to 100m spacing into Scimitar from a larger 397 hole program totalling 1,772m (RRAB532-RRAB928). 1994-1995 report (A.T. Price, 1995). 1995-1996 Poseidon Gold drilled 175 VAC holes (RAV0001-RAV0175) over the Scimitar prospect from a larger program of 602 holes for 2,976m. The Scimitar VAC holes were drilled at 50m x 500m spacing and intercepted sericite altered sediments and gossanous brecciated quartz veins. The drilling confirmed a strong As, Pb and Zn anomaly with a weaker 1-16ppb Au anomaly. A further 37 VAC holes (RCV0565-RCV0605) were drilled to the southwest of Scimitar (Price, 1996). 1996-1997 Normandy Gold took 49 composite lag samples (sample 339551-339599) of -6 to +1 fraction over Scimitar at 100m x 500m spacing over 3 traverses. (Warren & Worland, 1997). 1998-1999 Exodus Minerals collected 5 rock chips and 5 soils samples at Scimitar. Samples 5761RR, 5762RR and 5763RR returned anomalous Au (62ppb, 38ppb, and 17ppb); As (24,000ppm, 4,000ppm, and 4,700ppm); Pb (360ppm, 580ppm, and 90ppm); and Sb (180ppm, 96ppm, and 102ppm). (Greenaway, 1998 & Greenaway, 1999). Note that a further 11 rock chips have been attributed to Cowden, 2001; but do not actually appear in the Cowden, 2001 report. Sample 336053 returned 37ppm Bi, 580ppm Cu, 19ppm Mo and 260ppm Pb. 2012 – 2013 Prodigy Gold flew a Tempest airborne EM survey over the Reynolds Range area in June and July 2012. This identified a prominent 2km x 1km conductor at Scimitar. |

| Geology | Deposit type, geological setting and style of mineralisation. |
The geology of the Reynolds Range Project area was described by Rohde (2012) in the Prodigy Gold 2012 annual tenement report on EL 23655. The project covers Paleoproterozoic metasediments and intrusives in the central Aileron Province of the Arunta region. The surface geology has been mapped and described by the Northern Territory Geological Survey (NTGS) in the 1:250,000 scale Napperby (SF53-09) sheet and in more |

| detail by the Bureau of Mineral Resources on the special edition Reynolds Range Region 1:100,000 scale geological map. On a regional scale the area comprises polydeformed Paleoproterozoic Lander Group metasediments intruded by numerous felsic and mafic intrusive phases and overlain by slightly younger siliciclastic metasediments, including the Reynolds Range Group. The area is covered by complex regolith, with scree shedding from substantial hills cut by large drainage systems. The Company is exploring for sulphide related gold and associated base metal mineralisation. This could be shear related gold, VMS or IOCG deposits. These style of deposits are known in theprovince. |

reported through open file reporting by previous explorers. |
|
All new drill holes completed and assayed by Prodigy Gold with material |

| 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 material to the announcement has been excluded. |
|
Samples collected from the drill hole have been reported as they are |
||
considered geologically significant or above 0.1g/t Au, 5g/t Ag, 0.1% Cu, |
||
0.1% Pb, or 0.1% Zn. Samples not reported can be assumed to be below |

| 0.1g/t Au, 5g/t Ag, 0.1% Cu, 0.1% Pb, or 0.1% Zn. | ||
| 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. |
| 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 on diagrams. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalents are being reported. No metallurgical recovery testwork has been completed. |
|
| 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). Drill holes are angled so as to drill as close to perpendicular |
||
to structures 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. A collar plan and cross sections are provided for the completed diamond drill holes. |
| 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 are |
reported where sample is above 0.1g/t Au, 5g/t Ag, 0.1% Cu, 0.1% Pb, or |
||
0.1% Zn or where considered geologically significant; together with |
||
reference to previous exploration results of significance. Enrichment of |
||
| metals can occur in the near surface environment. Results of lag and rock | ||
| chip sampling are collected as in indication of the presence of metals | ||
| however the grades should not been seen as directly correlative with | ||
| future resources or mining, if any. Results of rock chip sampling can be | ||
| higher or lower the material below surface. |
