North Laverton Gold Project Resource Drill Programme (Bullseye Mining Limited - EMR: 59.44%)
The North Laverton Gold Project consists of 34 exploration licences (including 4 applications) and 4 mining licences covering the majority of the Dingo Range greenstone belt with more than 800km² of tenure (refer Figure 1) and has the potential to host multiple standalone deposits or satellite deposits to supply additional ore to a central mill. It includes the gold mineralised prospects of Boundary, Neptune, Stirling, Hurleys and Bungarra extending over a 6.4km strike length.
The planned ~98km resource definition drilling programme spans across the Boundary, Neptune, Stirling, Hurleys and Bungarra prospects. Once completed there will be circa 150,000m of new drilling available to estimate an updated North Laverton resource by the end of FY23 and a maiden reserve estimate to follow shortly thereafter.
Drilling during the initial stages of the programme has been limited to a single RC drill rig. This month a diamond rig has mobilised to site and commenced drilling. A third drill rig (RC) is expected to mobilise to site in Q3FY23 to escalate drilling capacity.
To date 255 collars (25,277m) of the 98,000m resource definition programme have been completed of which 59 collars (10,936m) has been completed since Emerald acquired a controlling interest in Bullseye. The initial drilling has been limited to the Boundary and Neptune prospects of the Boundary-Bungarra mineralised trend (Figure 2) with highlighted significant results including:
-
12m @ 4.94g/t from 62m including 1m @ 9.07g/t from 69m and 1m @ 42.90g/t from 72m (RC22NPT003)[(1)] ;

Memot Prospect infill RC Resource Programme
Emerald continues to progress an exploration drill programme at the Memot Project, focusing on infilling and extending the mineralisation proximally within and beyond the known mineralisation. The drilling to date includes 82 drill holes for 10,298m (5,948m RC and 4,350m diamond) with no assays pending (refer to Figure 9). Highlighted significant recent results (refer Appendix Five) received include:
-
1m @ 31.4g/t Au from 132m, 0.52% Cu and 0.52 % Zn (RC22MMT073);
-
3m @ 7.11g/t Au from 132m (RC22MMT074);
-
1m @ 21.30g/t Au from 69m and 1.06% Cu (RC22MMT039);
-
7m @ 2.18g/t Au from 69m including 1m @ 11.15g/t Au from 70m and 1.49% Cu (RC22MMT047);
-
4m @ 3.87g/t from 3m including 1m @ 12.95g/t Au from 4m (RC22MMT057);
-
7m @ 1.80g/t from 123m including 1m @ 10.00g/t Au from 127m (RC22MMT038);
-
1m @ 12.20g/t from 107m (RC22MMT065);
-
5m @ 1.81g/t from 17m including 1m @ 7.53g/t from 21m (RC22MMT077);
-
1m @ 8.03g/t from 144m (RC22MMT078).
Several of the collars completed also tested the edges of the known mineralisation and results indicate the mineralisation is open and untested in all directions. In particular, mineralisation is open along strike to the north-west and south-east and down dip to the north-east (refer Figure 9). This coincides with the previously announced significant Au and Cu in-soil anomaly indicating the known gold results are part of a potentially larger mineralised system (refer ASX announcement dated 28 July 2022).
The mineralisation is associated with at least three high-grade, narrow, stacked quartz vein sets, dipping shallowly to the north-east (refer Figure 9) with current interpreted strike length of 650m (refer ASX announcement dated 28 July 2022). The programme is investigating both down dip and along strike continuity of the structures.

A maiden resource calculation is planned for the end of FY23 utilising both the recent results and previously announced significant intersections, such as,
-
1m @ 37.20 g/t Au from 33m (DD21MMT005);
-
1m @ 31.70g/t Au from 49m (DD21MMT010); and 0.45m @ 37.10g/t Au from 74.55m,

A contractor has been engaged to complete ground magnetics/radiometrics and IP geophysical surveys over the prospective areas with anomalous Au and Cu geochemical signatures located within a ~6km radius of the Memot artisanal workings (refer ASX announcement dated 28 July 2022). Whilst both surveys have been completed, the data processing and interpretations are ongoing. The geophysical surveys will assist with the regional structural interpretation, as well as potentially identifying prospective exploration targets similar to intrusive centered, sediment hosted Au-Cu (Sepon) style mineralisation.

About Emerald Resources NL
Overview
Emerald is a developer and explorer of gold projects. In particular, Emerald has been focused on the development and commissioning of its most advanced project, the Okvau Gold Mine in Cambodia which saw first production in June 2021. Since commercial production commenced in September 2021, Emerald has now poured over 5,000kgs of gold doré from its operations.
Emerald also holds a number of other projects in Cambodia which are made up of a combination of granted mining licences (100% owned by Emerald) and interests joint venture agreements. Together, Emerald’s interest in its Cambodian Projects covers a combined area of 1,639km².
Emerald has a controlling interest in Bullseye Mining Limited (59.44%), an unlisted Australian public company with three Western Australian gold projects totalling in excess of 1,200km² of highly prospective gold tenure including the North Laverton Gold Project which covers in excess of 800km² of the entire Dingo Range greenstone belt.
Okvau Gold Mine
The Okvau Gold Mine Operation is the most advanced of Emerald’s projects. The Okvau Gold Mine is located approximately 275km north-east of Cambodia’s capital city of Phnom Penh in the province of Mondulkiri (refer Figures 10 and 11). The town of Kratie is located on the Mekong River approximately 90km to the west and the capital of Mondulkiri, Saen Monourom is located approximately 60km to the south-east.
The principal activity of the consolidated entity during the 2021 financial year was the development of Emerald’s 100% owned Okvau Gold Mine. On 26 June 2021 Emerald announced its maiden gold pour after successfully commissioning the processing plant and gold room. Subsequently, commissioning activities continued on the sulphide float regrind circuit which was successfully completed in July 2021. This marked the practical completion of the Okvau Gold Mine commissioning process and commencement of normal run of mine operations.

Appendix Two | JORC Code, 2012 Edition | ‘Table 1’ Report
Section 1 Sampling Techniques and Data from Recent Drilling at Neptune and Boundary Prospects (Bullseye)
(Criteria in this section apply to all succeeding sections).
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
• Standards are inserted in sample batches to test laboratory performance. • All Bullseye RC samples were put through a fixed cone splitter at 1m intervals with the sample reduced to between a 2kg to 4kg sample. • Bullseye drill programme used SGS Laboratories, Kalgoorlie for RC samples: • SGS – samples crushed and milled to <75µm and assayed using fire assay (50g) with additional AAS. |
| Drilling techniques |
• Drill type (eg 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). |
• A Schramm 685 drill rig is used to drill 5.5-inch RC holes. • All Bullseye RC holes were downhole surveyed using a gyroscopic survey tool (a REFLEX GYRO SPRINT-IQ™). A typical downhole survey was taken at 10m depth to the end of hole. All readings showed that down hole deviation was negligible. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the 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. |
• RC drill sample recovery averaged better than 99%. |
| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. |
• All RC chips and diamond core is routinely logged (qualitatively) by a geologist, to record details of regolith (oxidation), lithology, structure, mineralization and/or veining, and alteration. All logging and sampling data are captured into a database, with appropriate validation and security features. |
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. |
• Most samples are dry and there is no likelihood of compromised results due to moisture. • This sample technique is industry norm and is deemed appropriate for the material. • All RC samples were put through a fixed cone splitter at 1m intervals with the sample reduced to between a 2kg to 4kg sample. • The drilling used SGS Laboratories, Kalgoorlie for RC samples: SGS– samples dried at 105° Celsius, |

crushed and milled to 85% passing -75µm. Assay was 50g fire assay with AAS finish for gold. |
|
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
• All samples are sent to the accredited SGS Laboratories, Kalgoorlie 50g fire assay with AAS finish for gold. This method has a lower detection limit of 0.01ppm gold. • Industry-standard QAQC protocols are routinely followed for all sample batches sent for assay, which includes the insertion of commercially available pulp CRMs at rate of 1 for every 20 field samples and pulp blanks at a rate of 1 for every 50 field samples. Field duplicates were collected at the rig, directly from the cyclone at a rate of one in every 50 samples for the entire programme. • QAQC data are routinely checked before any associated assay results are reviewed for interpretation. • All assay data, including internal and external QA/QC data and control charts of standard, replicate and duplicate assay results, are communicated electronically. |
| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
• All field data associated with sampling, and all associated assay and analytical results, are archived in a relational database, with industry- standard verification protocols in place. • The calculations of all significant intercepts (for drill holes) are routinely checked by senior management. • Data verification and validation procedures undertaken included checks on collar position against design and site survey collar pick-ups by Licensed on site surveyors. Hole depths were cross-checked in the geology logs, down hole surveys, sample sheets and assay reports to ensure consistency. All down hole surveys were exposed to rigorous QAQC and drill traces were plotted in 3D for validation and assessment of global deviation trends. |
| Location of data points |
• Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. |
• The grid system used is MGA_94. The creation of the topographic surface is based on a site survey pick-up in March 2014 by GEMS (Glockner Engineering and Mining Services, licensed Australian surveyors) and again in July 2014, August 2015 and August 2017 of all drill holes and surface contour points in GDA_94. • To date the collars of holes drilled have been picked up by a hand GPS. Although it is the intention to use a licenced surveyor with DGPS equipment to pick up the collars before any resource calculation. • All Bullseye RC holes at Neptune were downhole surveyed using a gyroscopic survey tool (a REFLEX GYRO SPRINT-IQ™) and are routinely undertaken at ~5m intervals for the drilling |
| Data spacing and distribution |
• Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositinghas been applied. |
• This drill spacing is considered to be sufficient to establish geological and grade continuity appropriate for the declaration of estimates of resources. • The drill programme adopted a standard sample length of 1.0m. |

| 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. • 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. |
• Drill holes are usually designed to intersect target structures with a “close-to-orthogonal” intercept. • Most of the drill holes intersect the mineralised zones at sufficient angle for the risk of significant sampling orientation bias to be low. |
| Sample security | • The measures taken to ensure sample security. |
• All RC samples were sampled as single 1m calico samples, each with a unique sample number. These calicos were collected from the drill sites in allotments of 1 tonne bulka bags. These bulka bags were loaded by Bullseye field staff and delivered to SGS Kalgoorlie by road transport supplied by SGS. Zones of waste a sampled as a composite sample using the spear sampling technique. If the composite returns an anomalous value, the individual 1m samples (collected and stored at the time of drilling) are submitted for analysis. |
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data. |
• All QAQC data are reviewed routinely, batch by batch, and on a quarterly basis to conduct trend analyses, etc. Any issues arising are dealt with immediately and problems resolved before results are interpreted and/or reported. |
Section 2 Reporting of Exploration Results from Recent Drilling at Neptune and Boundary Prospects (Bullseye)
(Criteria listed in the preceding section also apply to this section)
| Criteria | Explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaininga licence to operate in the area. |
• The Neptune and Boundary Gold Prospects are 100% held by Bullseye Mining Limited (EMR 59.44%). The tenure is considered to be secure. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Historical drilling was conducted between 1989 – 2005 by companies Julia Mines NL, Eagle Mining NL,DeepYellow NL and Korab Resources Ltd. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• Geology comprises a basalt country rock and BIF. The Neptune deposit is associated with an approximately 45 degree plunging mineralised lode (or sheets) that have formed in association with the basalt/BIF contact, a large antiform structure and a large cross cutting structure. Gold Mineralisation is as shallow as a few metres below surface, extends to some 100m below surface and is open at depth. • The weathering profile displays a surface laterite, followed by clay/saprolite weathering predominately in association with the weathered basalt. Saprock is encountered earlier in association with weathered BIF. Global fresh rock is encountered from 70m down hole, but weathering is not well advanced at Neptune and hard saprock and fresh rock are encountered in more shallow horizons. |
| 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: |
• Details of significant drilling results are shown in Appendix One. |

| Criteria | Explanation | Commentary |
- easting and northing of the drill hole collar; - elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar; - dip and azimuth of the hole; - down hole length and interception depth; - hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
||
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearlystated. |
• No high grade top cuts have been applied. • The reported significant intersections in Appendix One are above 2 gram metre intersections and allow for up to 4m of internal dilution with a lower cut trigger values of greater than 0.5g/t. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
• All reported intersections are down hole lengths. True widths are unknown and vary depending on the orientation of target structures. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Appropriate maps and sections are included in the body of this 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 drilling results being intersections with a minimum 2 gram metre values are reported in Appendix One. |
| 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 contaminatingsubstances. |
• Surface geological mapping and detailed structural interpretation have helped inform the geological models. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commerciallysensitive. |
• Additional drilling programmes are being planned across all exploration licences. |

Appendix Four | JORC Code, 2012 Edition | ‘Table 1’ Report
Section 1 Sampling Techniques and Data from 2017 Historic Bullseye Drilling
(Criteria in this section apply to all succeeding sections).
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) maywarrant disclosure of detailed information. |
• The drill results reported were drilled with RC between March 2017 and May 2017. • The Bullseye completed RC holes were processed through a fixed cone splitter in 1m intervals to reduce the RC sample to between a 2kg to 4kg sample. • Bullseye undertook field investigations to confirm collar locations (with a licenced surveyor and DGPS equipment) and evidence of work areas. The findings of this field investigation corresponded well with the reported works. • The Bullseye drill holes had standard samples inserted in sample batches to test laboratory performance. The historic drilling’s use of standards is unknown. • The Bullseye drill programmes used the following labs and methodology: • Bureau Veritas, Kalgoorlie; Milled to <75um and assayed using fire assay (40g) with additional atomic absorption spectrometry (AAS). |
| Drilling techniques |
• Drill type (eg core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so,bywhat method,etc). |
• The drill results reported were drilled with RC using a 5.5 inch hammer. • All collars completed by Bullseye were picked up by a licensed onsite surveyor. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the 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. |
• All Bullseye RC 1m samples and sub-samples (pre- and post-split) are weighed at the drill rig, to check that there is adequate sample material for assay. Any wet or damp samples are noted and that information is recorded in the database; samples are usually dry. Both the Bullseye RC and Diamond sample recovery was +95% recovery. • It is not possible to confirm the relationship between sample recoveryandgrade. |
| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. |
• All holes drilled by Bullseye Mining Limited have been geologically logged. Logging recorded lithology, mineralogy, alteration, weathering, texture, sulphide content, veining and macro structure; • The geological legend has evolved from historic observations and recent logging determinations and is consistent with the regional and local geology; |

| Criteria | JORC Code explanation | Commentary |
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material beingsampled. |
• All Bullseye Mining Limited RC samples were processed through a fixed cone splitter at 1m intervals with the sample to reduce the RC sample to between a 2kg to 4kg sample. Any wet or damp samples are noted and that information is recorded in the database; samples are usually dry. Assaying was completed at Bureau Veritas – samples dried at 85° Celsius, crushed and milled to 90% passing -75µm. Assay was 40g fire assay with AAS finish for gold. |
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
• The Bullseye Mining Limited drill programmes followed Industry-standard QAQC protocols • QAQC protocols are routinely followed for all sample batches sent for assay, which includes the insertion of commercially available pulp CRMs at rate of 1 for every 20 field samples and pulp blanks at a rate of 1 for every 50 field samples. Field duplicates were collected at the drill rig, directly from the cyclone at a rate of one in every 50 samples for all Bullseye Mining Limited drilling programmes. |
| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
• All field data associated with sampling, and all associated assay and analytical results, are archived in a relational database, with industry-standard verification protocols in place. • Data verification and validation procedures undertaken by Bullseye included checks on collar position against design and site survey collar pick-ups by GEMS. Hole depths were cross-checked in the geology logs, down hole surveys, sample sheets and assay reports to ensure consistency. All down hole surveys were exposed to rigorous QAQC and drill traces were plotted in 3D for validation and assessment of global deviation trends. • Bullseye have conducted a comparison of historic drilling holes against the recent Bullseye Mining Limited drill programme results. The comparison has showed solid correlation between the historic priority one holes and the recent drilling for both geology and grade. |
| Location of data points |
• Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. |
• The grid system used is MGA_94. The creation of the topographic surface is based on a site survey pick-up by GEMS; • Collars of holes drilled by Bullseye Mining Limited have been picked up by GEMS or alternative licensed on-site surveyor using a Trimble GNSS DGPS. Where identified, historical drill holes have also been picked using the DGPS; • The Bullseye RC and diamond holes were downhole surveyed using a gyroscopic survey tool. Vertical holes were not surveyed. |
| Data spacing and distribution |
• Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree ofgeological |
• This drill spacing is considered to be sufficient to establish geological and grade continuity appropriate for the declaration of estimates of resources. |

and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. |
||
| 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. • 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. |
• Drill holes are usually designed to intersect target structures with a “close-to-orthogonal” intercept. • Most of the drill holes intersect the mineralised zones at sufficient angle for the risk of significant sampling orientation bias to be low. |
| Sample security | • The measures taken to ensure sample security. |
• All RC samples were sampled each with a unique sample number. These calicos were collected from the drill sites in allotments of 1 tonne bulka bags. These bulka bags were loaded by Bullseye field staff and delivered to respective Laboratories byroad freight. |
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data. |
• All QAQC data are reviewed routinely, batch by batch, and on a quarterly basis to conduct trend analyses, etc. Any issues arising are dealt with immediately and problems resolved before results are interpreted and/or reported. |
Section 2 Reporting of Exploration Results from Historic (2017) Bullseye Drilling
(Criteria listed in the preceding section also apply to this section)
| Criteria | Explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaininga licence to operate in the area. |
• The Neptune Gold Project is 100% held by Bullseye Mining Limited (EMR:59.44%). • All tenure is considered to be secure. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Historical drilling was conducted between 1989 – 2005 by companies Julia Mines NL, Eagle Mining NL, Deep Yellow NL and Korab Resources Ltd. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• Neptune: geology comprises a surrounding basalt country rock and banded iron formation (BIF). The Boundary deposit is associated with quartz veining in weathered saprolite and saprock predominately overlying a steeply plunging granodiorite. Gold Mineralisation is within the quartz veins but extends well into the fresh granodiorite to a depth of some 160m below surface. Additional gold mineralisation is seen in the surrounding basalt proximal to the contacts with the granodiorite; • The weathering profile has a partially oxidized ‘saprock’ unit overlying fresh rock at about 50m depth in the north deepening to about 70m in the south, forming a weathered basin overlying the granodiorite. Within the basin, a saprolite unit occurs in association with a more extensive clay/sand (palaeochannel) infill zone and an extensive laterite overlies all units. |
| 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; |
• Details of significant drilling results are shown in Appendix Three. |

| Criteria | Explanation | Commentary |
- elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar; - dip and azimuth of the hole; - down hole length and interception depth; - hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
||
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• No high grade top cuts have been applied. • The reported significant intersections in Appendix Three are above 2 gram metre intersections and allow for up to 4m of internal dilution with a lower cut trigger values of greater than 0.5g/t. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
• The majority of the drill holes intersect the mineralised zones at sufficient angle for the risk of significant sampling orientation bias to be low. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Appropriate maps and diagrams are included in the body of this 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. |
• Significant drilling results above 2 gram metre are reported in Appendix Three. |
| 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. |
• Surface geological mapping and detailed structural interpretation have helped inform the geological models. • Initial metallurgical, geotechnical and hydrogeological drilling has been carried out. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commerciallysensitive. |
• Additional drilling programmes are being planned across all exploration licences. |

Appendix Six | JORC Code, 2012 Edition | ‘Table 1’ Report
Section 1 Sampling Techniques and Data from New Significant Intercepts Memot Prospect RC Drill Programme
(Criteria in this section apply to all succeeding sections).
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3kg was pulverised to produce a 30g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
• Standards are inserted in sample batches to test laboratory performance. • For the recent Memot RC drill, reverse circulation (RC) drilling is used to collect both a 4m composite and 1m samples in the precollar. The 4m programme composited are taken from the excess bagged material off the cone splitter taken every 1m. A spear sampling technique is then used to produce a 3-5kg composite sample. The 1m samples are split with a cone splitter at the drill rig to produce a 3-5kg sub- sample. These 1m samples are submitted after the results of the 4m composites are received to identify the zones of mineralisation. • The Exploration drill samples preparation is carried out at a commercial off-site laboratory (ALS Phnom Penh). Gold assays are conducted at ALS Vientiane, Laos utilising a 50gram subsample of 85% passing 75µm pulped sample using Fire Assay with AAS finish on and Aqua Regia digest of the lead collection button. Multi- element assay is completed at ALS, Perth, Australia on a 1g pulp subsample digested by Aqua Regia and determined by ICP-AES or ICP-MS for lowest available detection for the respective element. |
| Drilling techniques |
• Drill type (eg 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). |
• A track mounted Longyear DB350 rig is used to drill 5.5-inch RC precollar holes. Recent drilling used a REFLEX survey tool to survey hole deviation. A typical downhole survey was taken at 12m depth and then every 30m to the end of hole. Surveying of RC holes utilises 6m of stainless drill rod to negate the magnetic interference from the rod string and hammer assembly. All readings showed that down hole deviation was negligible. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the 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. |
• All RC 1m samples and sub-samples (pre- and post- split) are weighed at the rig, to check that there is adequate sample material for assay. Any wet or damp samples are noted and that information is recorded in the database; samples are usually dry. |
| Logging | • Whether core and chip samples have been geologicallyandgeotechnicallylogged to a |
• All RC chips and diamond core is routinely logged (qualitatively)byageologist,to record details of |

level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. |
regolith (oxidation), lithology, structure, mineralisation and/or veining, and alteration. In addition, the magnetic susceptibility of all samples is routinely measured. All logging and sampling data are captured into a database, with appropriate validation and security features. • Standard field data are similarly recorded (qualitatively) routinely by a geologist for all soil samplingsites. |
|
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material beingsampled. |
• Most samples are dry and there is no likelihood of compromised results due to moisture. • All samples were prepared for assay at the NATA accredited ALS Cambodia sample preparation facility in Phnom Penh; and that facility has been inspected, at the request of the Company, numerous times and most recently by Mr Keith King in April 2022. Samples are dried for a minimum of 12 hours at 105˚C. • This sample technique is industry norm and is deemed appropriate for the material. |
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
• All samples are sent to the NATA accredited ALS Laboratory in Vientiane, Laos, for single Aqua Regia digest with a 50g charge with an ICP-MS finish. Samples are sent to the similarly accredited ALS Lab in Brisbane, Australia and ALS Lab Perth, Australia, for multi-element ICP analysis, after partial extraction by aqua regia digest then via a combination of ICP-MS and ICP-AES. This method has a lower detection limit of 1ppm gold. • Industry-standard QAQC protocols are routinely followed for all sample batches sent for assay, which includes the insertion of commercially available pulp CRMs and pulp blanks into all batches - usually 1 of each for every 20 field samples. Additional blanks used are home-made from barren quarry basalt. QAQC data are routinely checked before any associated assay results are reviewed for interpretation, and any problems are investigated before results are released to the market - no issues were raised with the results reported here. • All assay data, including internal and external QAQC data and control charts of standard, replicate and duplicate assay results, are communicated electronically. |
| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
• All field data associated with sampling, and all associated assay and analytical results, are archived in a relational database, with industry-standard verification protocols and security measures in place. • The calculations of all significant intercepts (for drill holes) are routinely checked by senior management. • All field data associated with drilling and sampling, and all associated assay and analytical results, are archived in a relational database, with industry- standard verification protocols and security measures inplace. |
| Location of data points |
• Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of thegrid system used. |
• Whilst, all sample locations are first surveyed with a hand-held GPS instrument (which generates relatively inaccurate RL values), not all samples were insitu. All locations are surveyed to WGS 84. |

• Quality and adequacy of topographic control. |
• Drill hole collar locations are first surveyed with a hand-held GPS instrument (which generates relatively inaccurate RL values). The locations of all holes used in Mineral Resource estimates are verified or amended by survey using a differential GPS by and external contractor with excellent accuracy in all dimensions using a local base station reference). • To date the newly reported collars of holes drilled have been picked up by a hand GPS. Although it is the intention to use a licenced surveyor with DGPS equipment to pick up the collars before any resource calculation. • Down-hole surveys are routinely undertaken at 30m intervals for all types of drilling, using a single-shot or multi-shot REFLEX survey tool (operated by the driller and checked bythe supervising geologist). |
|
| Data spacing and distribution |
• Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. |
• This drill spacing is considered to be sufficient to establish geological and grade continuity appropriate for the declaration of estimates of resources. |
| 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. • 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. |
• Drill holes are usually designed to intersect target structures with a “close-to-orthogonal” intercept. • Drilling has been done at various orientations. • Most of the drill holes intersect the mineralised zones at sufficient angle for the risk of significant sampling orientation bias to be low. |
| Sample security | • The measures taken to ensure sample security. |
• The chain of custody for all drill samples from the drill rig and soil/auger samples from the field to the ALS Sample Preparation facility in Phnom Penh is managed by Renaissance personnel. Drill samples are transported from the drill site to the Okvau exploration core farm, where they are logged and all samples are batched up for shipment to Phnom Penh. • Sample submission forms are sent to the ALS Sample Prep facility in paper form (with the samples themselves) and also as an electronic copy. Delivered samples are reconciled with the batch submission form prior to the commencement of any sample preparation. • ALS is responsible for shipping sample pulps from Phnom Penh to the analytical laboratories in Vientiane, Brisbane and Perth and all samples are tracked via their Global Enterprise Management System. • All bulk residues are stored permanently at the ALS laboratoryin Vientiane. |
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data. |
• All QAQC data are reviewed routinely, batch by batch, and on a quarterly basis to conduct trend analyses, etc. Any issues arising are dealt with immediately and problems resolved before results are interpreted and/or reported. • Comprehensive QAQC audits have been conducted on this project by Duncan Hackman (August 2009, February 2010 & November 2011), SRK (February 2013) and Nola Hackman (January 2014), Wolfe (July 2015). |

• Mr Brett Gossage reviewed the data used in the Okvau Resource up to December 2016 and concluded that there are no concerns about data quality. • Keith King completed his most recent site visit and lab audit of the ALS Phnom Penh facilities in April 2022. |
Section 2 Reporting of Exploration Results from New Significant Intercepts Memot Prospect RC Drill Programme
(Criteria listed in the preceding section also apply to this section)
| Criteria | Explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaininga licence to operate in the area. |
• The licences are held (100%) in the name of Renaissance Minerals (Cambodia) Limited which is a wholly owned subsidiary of Emerald Resources NL. • The tenure is considered to be secure. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Exploration has been completed by previous explorers; Oxiana and Oz Minerals including soil sampling, geophysical data collection and drilling. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• Gold occurrences within the licences is interpreted as either a “intrusion-related gold system” or “Porphyry” related mineralisation. Gold mineralization is hosted within quartz and/or sulphide veins and associated within or proximal distance to a Cretaceous age diorite. |
| Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: - easting and northing of the drill hole collar; - elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar; - dip and azimuth of the hole; - down hole length and interception depth; - hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• Details of significant drilling in Appendix Five. |
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• No high grade top cuts have been applied. • The reported significant intersections in Appendix Five are above 2 gram metre intersections and allow for up to 4m of internal dilution with a lower cut trigger values of greater than 0.5g/t. |
| Relationship between mineralisation |
• These relationships are particularly important in the reporting of Exploration Results. |
• All reported intersections are down hole lengths. True widths are unknown and vary depending on the orientation of target structures. |

| Criteria | Explanation | Commentary |
| widths and intercept lengths |
• If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
|
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Appropriate maps and sections are included in the body of this 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 drilling results being intersections with a minimum 2 gram metre values are reported in Appendix Five. |
| 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 contaminatingsubstances. |
• All mineralisation is associated with visible amounts of pyrrhotite or arsenopyrite. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commerciallysensitive. |
• Further drilling programmes are being planned on additional nearby targets. • Additional drilling programmes are being planned across all exploration licences. |
