Prodigy Gold NL (ASX: PRX) (‘Prodigy Gold’ or the ‘Company’) is pleased to announce the receipt of the initial results for the reverse circulation (“RC”) drilling program completed at the Tregony deposit, part of the Company’s Tanami North Project in the Northern Territory (Figure 1).
The results received are from the initial 15 holes of the 37 hole, 4,840 metre RC program completed at the Tregony deposit, which was designed to improve confidence and potentially increase the metal inventory of the Tregony mineral resource that was released in February this year[1] . The received results returned a series of significant intercepts based on a 0.5 g/t gold cut-off, including the highergrade highlights, 3 metres @ 10.7 g/t gold, 6 metres @ 15.7 g/t gold, 6 metres @ 12.0 g/t gold and 4 metres @ 14.0 g/t gold. The results for the remaining 22 holes are expected to be available during October and November 2023.
The Tregony deposit is located in a highly prospective, underexplored area situated between the 1.1 Moz Groundrush deposit and the 94 Koz Crusade deposit[2] , both of which form part of the neighboring Central Tanami Project, a 50/50 Joint venture between Northern Star Resources Limited (ASX:NST) and Tanami Gold NL (ASX:TAM). Tregony is also located around 25 kilometres to the north of Prodigy

Management Commentary
Prodigy Gold Managing Director, Mark Edwards said:
“The Tanami North Project area is a key strategic area of focus for Prodigy Gold. The drilling that has been completed is based around the two mineral resources reported for this project with the plan of improving confidence as well as potentially expanding the size of these mineral resources. These first results are very encouraging and support this plan moving forward. The results from the full program will be used to review the current mineral resource, which is likely to be updated over the wet season when exploration fieldwork is not possible.
The initial results from drilling highlighted the potential for higher gold grades with logging of two of the drilled intervals showing visible gold in the RC chips. It is a good indicator for possible higher grade

zones within the Tregony deposit, which will be better understood with further drilling, particularly the co-funded diamond hole that is planned to be completed later this year.
Prodigy Gold looks forward to releasing more drill results as they come to hand, with results for the remaining holes at Tregony as well as results from the drilling just completed at Hyperion expected during October 2023.”

Tregony 2023 RC Drilling Programs
The Tregony deposit is located on EL31331, 125km south-west of Lajamanu in the Tanami Region of the Northern Territory (Figure 1). The deposit was systematically explored by AngloGold Ashanti (AGA) between 1995 and 2000 following up surface geochemical sampling by Messenger and Dominion Mining in the early 1990’s. Small RC drilling programs were completed by Ord River Resources between 2004 and 2012. Prodigy Gold purchased the Tregony deposit from Ord River Resources in 2014[4] .
The Tregony deposit is hosted within the regional Suplejack Shear Zone (SSZ) over a strike length of around 3km. Mineralisation is represented in a stacked vein style model hosted within the sediments

of the Killi Killi Formation. There are over 50 mineralised lodes defined in the current resource, ranging in thickness from 2m to up to 15m wide. Mineralisation wireframes were defined using a lower cutoff of 0.3g/t Au, however some areas of waste were also included to ensure continuity of the wireframes. The initial drill results received support this wireframe interpretation.
The Tregony drilling campaign covers an area in and around the current inferred mineral resource for Tregony. All intercepts received to date are reported in Table 1 and have been calculated at a lower cut-off grade of 0.5g/t gold using a minimum width of 2m and can include a maximum of 2m of contiguous lower grade material. At least six individual samples returned grades above 10g/t Au, which is the high-grade cut level used in the mineral resource estimation. No high-grade cut has been used in calculating the reported intercepts.

Bold intercepts reported above average Tregony mineral resource grade
Visible gold has previously been noted to occur at Tregony from earlier drill campaigns. Visible gold was reported in the diamond core drilling completed in 2021[5] , as well as being noted in two one metre samples in the recent drilling program, both within drill hole TGRC23004 (Table 1 & Figure 4).

For grade interval calculations, the intercepts represent down hole lengths, which closely match the actual true widths, due to the dip of the mineralisation being close to perpendicular to the drill holes. No true width estimates have been included in the reported results (Figure 3).
The results as reported cover the first 15 of the 37 holes completed over June and July this year. The remaining holes are being submitted to the laboratory for analysis with results expected in October and November. Results will be reported upon the successful review of all QAQC outcomes.
As previously reported, RC drilling of 24 holes for a total of 2,566m[6] was also completed at the Hyperion deposit 25 kilometres to the south of the Tregony deposit. These results are expected during October.

Both, Tregony and Hyperion, drilling campaigns will be used to review and update the current mineral resource estimates, it is planned to complete this work over the upcoming wet season. These results will also be used to assist with planning the next phase of drilling for both projects. The Tanami North Project area is strategically important for Prodigy Gold and will remain a focus for exploration and development over the coming years.

JORC TABLE 1 TREGONY 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. |
• RC drilling was completed using two Schram 685 drill rigs. • RC drilling techniques are used to obtain 1m samples of the entire downhole length. RC samples are logged geologically and all samples submitted for assay |
| 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 as per industry best practice. Bag sequence is checked regularly by field staff and supervising geologist against a dedicated sample register. See further details below. The cyclone and splitter were routinely cleaned. |
|
| 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 |
RC samples were taken using a 10:1 Sandvik static cone splitter mounted under a polyurethane cyclone to obtain 1m samples. Approximately 3kg samples were submitted to the lab. Prodigy Gold samples were submitted to Bureau Veritas Adelaide for crushing and pulverising to produce a 40g charge for Fire Assay with AAS finish. Samples from selected drill holes were placed into green bags for possible future use if assays suggest the presence of coarse gold. Samples may be submitted for full analysis to determine the possible presence of coarse gold. |
|
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-hole | RC drilling was completed by both TopDrill and Bullion using Schramm 685 |
| 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.). |
RC drill rigs with a booster compressor. The drill hole diameter was 51/2 inch and downhole surveys for RC drilling are recorded using a True North seeking GYRO survey tool. |
|
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed |
Sample recoveries are recorded on sample registers with sample recovery and moisture content estimated. Good sample recovery was standard in the program. All samples are weighed at the laboratory and reported as a part of standard preparation protocols. No water compromised samples were reported in thisprogram. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples |
Drilling is carried out orthogonal to the mineralisation to get representative samples of the mineralisation. RC samples are collected through a cyclone and cone splitter. The sample required for the assay is collected directly into a calico sample bag at a designed 3kg sample mass which is optimal for full sample crushing and pulverisation at the assay laboratory. Samples from selected holes within the Tregony resource area were collected in green bags and the green bags and calico bag were weighed to assist with assessingdrill hole recoveries. |

| 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. |
Sample bias due to preferential loss/gain of fine/coarse material from the RC drilling is unlikely. No relationship between sample recovery and grade is known at this stage. |

1 metre RC samples were split with a cone splitter mounted under a polyurethane cyclone. All intervals were sampled if the sample was wet it was recorded by the responsible geologist. Very few wet samples were reported. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
All samples were 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 was 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. |
Standards, field duplicates and blanks were inserted every 20 samples (1:20). At the laboratory, regular repeat and Lab Check samples are assayed. Duplicate samples were collected either by using the second chute on the cyclone or manuallyusinga standalone riffle splitter. |
|
| 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. |
Samples were split using cone splitter attached to the drill rigs, which was checked to be level for each hole. Sample weights were monitored to ensure adequate sample collection was maintained. The cone splitter provided some variability in sample weights from 2-4kg. Field duplicates were collected for selected intervals using either the second chute attached to the cone splitter on the cyclone or manually using a standalone 50:50 riffle splitter. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |

with an ICP-AAS (atomic absorption spectroscopy) finish. The lower detection limit for this technique is 0.01ppm Au and the upper limit is 1,000ppm Au that is considered appropriate for the material and mineralisation and is industry standard for this type of sample. In addition to standards, duplicates and blanks previously discussed, Bureau Veritas conducted internal lab checks using standards, blanks. Three samples were analysed using the Screen Fire Assay method due to the observation of the rock chips at the time of logging. Samples which showed the potential of hosting very high grades were analysed by taking a 1,000 gram sample, screen the sample to fine and coarse samples and analysing the coarse sample to extinction using the fire assay method as outline above. A grade is then calculated by combining the results of the fine and coarse sample analysis. This is deemed as a more appropriate method when intersecting very high gold samples, particularly when visiblegold is logged in rock chips. |

| 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. The interface to the MDS used is DataShed version 4.62 and SQL 2017 standard edition. 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 and integrity 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, providing full audit trails to meet industry best practice. The database is backed up in daily basis and also external copies are made to keep the backups outside the company premises,preventingto lose the backupfor any potential disaster. |

SECTION 2: REPORTING OF EXPLORATION RESULTS
| 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 Tregony drilling area is contained within EL31331 located in the Northern Territory. The exploration licence (EL) is wholly owned by Prodigy Gold, and subject to a confidential indigenous land use agreement (ILUA) between Prodigy Gold and the Traditional Owners via the Central Land Council (CLC). A heritage clearance has been completed prior to drilling to ensure the protection of cultural sites of significance. A NT mine management plan is in place for the exploration on the EL. |

| Geology | Deposit type, geological setting and style of mineralisation. |
The structurally controlled gold deposit consists of an array of quartz veins within the sediments (sandstones and siltstones) of the Killi Killi Formation, with some exceptionally high historic gold grades. The gold bearing veins are concentrated in the near hanging wall (east) of the regionally significant Suplejack Fault. Mineralisation extends from the surface to the current depth of drilling. Gold of over 0.3g/t Au is continuous for up to 10km, with 4-5 high grade shoots defined within the 4km of the deposit drilled with RC and diamond drilling. |
| Drill hole Information |

| 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 Au 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. |
|
| 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 to drill as close to | ||
| perpendicular to structures as possible. Mineralisation is reported with | ||
| 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. A collar plan is provided for the completed drill holes. Cross sections are provided within the release. |
| 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 significant intersections are reported with a 0.5g/t Au lower cut-off. |
| 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. |
Information relevant to the results has been provided. |
| 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 drilling is anticipated and will be planned once results have been |
| analysed by the Company. | ||
