North Laverton Gold Project Resource Drill Program (Bullseye Mining Limited (EMR: ~78.05%))
Bullseye’s North Laverton Gold Project consists of 36 exploration licences (including 5 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 milling location. It includes the gold mineralised prospects of Boundary, Neptune, Stirling, Hurleys and Bungarra extending over a 6.4km strike length.

==> picture [531 x 388] intentionally omitted <==
Drilling results to date (current and historical) continue to demonstrate the continuity of mineralisation at depth and along strike. The company still expects to generate an updated resource in early 2024, with subsequent reserve estimation to support a decision to commence development activities later in the same year (2024).
Two RC percussion drill rigs and one Diamond drill rig are currently engaged on site, continuing resource drilling activities and investigating along strike extensions, as well as drilling other regional targets.
In the December 2023 quarter, the Company completed 110 collars (16,994m) of both RC (14,013m) and Diamond core drilling (2,981m). To date 591 collars (75,664m) of the 98,000m resource definition program has been completed, of which 388 collars (60,099m) has been drilled since Emerald acquired a controlling interest in Bullseye. Assays for circa 1,400m of drilling remain pending.
Recently returned results from the current RC and diamond drilling program for the Boundary Project include:
-
3.26m @ 111.79g/t Au from 214.74m including 0.86m @ 422.00g/t Au from 214.74m (DDRE-BDRC017)[(6)]

Results from drilling to date continue to delineate mineralised high-grade structures. Historical drilling had only tested to ~110m vertical depth (average) with the drilling completed by the Company to date infilling and extending a significant portion of the mineralisation at Boundary and Neptune Prospects to ~200-250m vertical. The mineralisation remains open at depth and along strike throughout a significant portion of the five prospects (refer Figures 3, 4, and 5).

Okvau Gold Mine (EMR 100%)
In August 2023, the Company released an Okvau Gold Mine resource update which included a maiden underground resource.
Since the update, Emerald has continued to progress an exploration drill program, focusing on infilling and extending the currently open pit and maiden underground resource mineralisation proximally within and beyond the reserve pit shell. This drilling included an additional 37 holes, 22 of which were shallow RC for 3,669m and 15 of which were 3,362.2m of RC PreCollar and 6,406.5m of diamond core tails (refer Figures 8,10 and 11). Significant results received include:
-
19m @ 5.32g/t Au from 379m including 2m @ 14.03g/t Au from 391m (RCDD23OKV496);
-
13m @ 7.00g/t Au from 343m including 2m @ 33.11g/t Au from 343m (RCDD23OKV496);
-
7m @ 6.87g/t Au from 483m including 1m @ 27.00g/t Au from 485m (RCDD23OKV496);
-
4m @ 11.83g/t Au from 278m including 1m @ 37.50g/t Au from 278m (RCDD23OKV503);
-
4m @ 9.82g/t Au from 250m (RCDD23OKV497);
-
1m @ 38.30g/t Au from 340m (RCDD23OKV506);
-
7m @ 5.11g/t Au from 366m (RCDD23OKV496);
-
2m @ 17.80g/t Au from 273m (RCDD23OKV502); and
-
4m @ 6.26g/t Au from 55m (RC23OKV515).
The mineralisation is associated with massive sulphide pyrrhotite, arsenopyrite and pyrite stack vein sets hosted in both diorite and hornfels sedimentary lithologies.
The significant intercepts listed above are either outside the existing resource and likely to extend the known mineralisation or upgrade the classification of inferred material, enhancing our confidence in the existing resource (refer Figure 10 and 11).

==> picture [137 x 33] intentionally omitted <==
29 April 2022 In addition to the at depth extensional drilling reported above, the Company has also commenced a program of near surface extensional drilling in the northern extent of the existing reserve pit. The close-spaced drilling has returned the following significant results that are interpreted as the up-dip extension of the significant intercept 4m @ 6.26g/t Au from 55m in RC23OKV515 (see Appendix Three). This new zone of mineralisation is being assessed in a local redesign and expansion of the current pit. Intersections from this drill program include (see Appendix Three);
-
5m @ 23.5g/t Au from 15m (145_825_036);
-
7m @ 8.98g/t Au from 11m (145_745_008);
-
7m @ 7.76g/t Au from 16m (145_745_007);
-
9m @ 3.53g/t Au from 7m (145_825_027);
-
1m @ 21.24g/t Au from 27m (145_745_007);
-
2m @ 10.54g/t Au from 24m (145_835_015); and
-
5m @ 3.90g/t Au from 7m (145_815_025).

Antrong Joint Venture (EMR earning up to 80%)
The Company has previously announced a significant gold-in-soil anomaly on the Kang Roland North prospect in the Antrong North Exploration licence (refer ASX announcement 30 October 2023). The interpreted 2.5km by 1.5km +50ppb goldin-soil contour is associated with aeromagnetic geophysical targets, high-grade rock chip results (50.30, 41.00, 32.30, 22.10,16.45 and 15.35g/t Au) and peak shallow soil results of 842, 788, 611, 513, 434, 359 ppb Au (refer Figure 12).
Figure 12 | Antrong North (Kang Roland North prospect) shallow soil and rock chip results completed by Emerald
==> picture [475 x 330] intentionally omitted <==
Following on from the shallow soil program on the Antrong North Exploration Licence, the Company has continued the Auger soils geochemical sampling, collecting 4,641 samples on the Antrong South Licence (Antrong and O’Thmey Prospects) (refer Figure 14). 5,424 Auger samples have been collected since the program began in 2023, with 880 results pending. Results received to date include 86 samples over 50ppb Au including 2720, 2680, 895, 675, 534, 493 and 427 ppb Au. The results have identified several significant +10ppb Au anomalies over both prospects. Fourteen gold-in-soil anomalies have been interpreted on the Antrong prospect including three at over 1.0 x 0.4km in size and a larger 1.7 x 0.6km anomaly on the O’Thmey prospect (refer Figures 12 and 13).
The initial program commenced in April 2023 and was designed on various grid spacings from 400m x 100m down to 200m x 100m. The current program has infilled down to 50 x 50m grid spacing on the areas with anomalous results. The program was planned to cover an interpreted diorite intrusive associated with aeromagnetic geophysical targets, historic and recently sampled high-grade rock chip (155.50g/t[(1)] , 146.50g/t[(1)] , 120.00g/t[(2)] , 78.0g/t[(1)] , 76.10g/t[(2)] , 64.90g/t[(1)] , 47.80g/t[(1)] , 46.10g/t[(1)] Au) and significant drill hole results[(2) ] such as:

| 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 at regular intervals in sample batches to test laboratory performance. • All Bullseye reverse circulation (RC) drilling is used to collect both a 4m composite and 1m samples in the precollar. The 4m composite are determined based on areas of known very low or background mineralisation or geological assessment at the rig. The 4m program composites 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. • Diamond core was sampled using half-core where the core is cut in half down the longitudinal axis and sample intervals were determined by the geologist based on lithological contacts, with most of the sample intervals being 1 metre in length. In areas of no mineralised (negligible amounts of alteration/sulphides typically present with mineralisation) a 2m composite was submitted. • The Bullseye drill program used SGS Laboratories, Kalgoorlie and Bureau Veritas Kalgoorlie for RC and Diamond samples: • SGS – samples crushed and milled to <75µm and assayed using fire assay (50g) with additional AAS. • Bureau Veritas – samples crushed and milled to <75µm (90% pass) and assayed using fire assay (40g) 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 with a 5.5-inch hammer and a Schramm 450 with a 5.375-inch hammer is used for RC drilling. • 5 3/8 hole were used to drill the RC holes. A UDR1000 rig is used to drill NQ2 Diamond Core. • All Bullseye 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 deviations were within acceptable limits. |
| 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. • 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 being sampled. |
• Most samples are dry and there is no likelihood of compromised results due to moisture. • This sample technique is industry standard 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 5kg sample. • The drilling used SGS Laboratories, Kalgoorlie and Bureau Veritas, Kalgoorlie for RC samples: SGS– samples are dried at 105° Celsius, crushed and milled to 85% passing -75µm. Assay was 50g fire assay with AAS finish for gold. Bureau Veritas– samples are dried at 105° 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, spectrometres, handheld XRF instruments, etc, the parametres 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 or the accredited Bureau Veritas laboratory in Kalgoorlie for 40g fire assay with AAS finish for gold. These methods have 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 program. • 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 Licenced 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, licenced Australian surveyors) and again in July 2014, August 2015 and August 2017 of all drill holes and surface contour points in GDA_94. • Collars drilled prior to 20 December 2023 have been picked up using Trimble RTK DGPS by Insight UAS authorised surveyors. Drillholes drilled after 20 December 2023 have been picked up using a hand GPS. These collars will be picked up using DGPS in future survey campaigns. It is the intention to use a licenced surveyor with DGPS equipment to pick up relevant collars prior to any resource calculation. • All Bullseye drill holes 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 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. • The drill program 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 or Bureau Veritas by road transport supplied by the relevant laboratory. 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. • Keith King completed his most recent site visit and lab audit of both the SGS Kalgoorlie and Bureau Veritas Kalgoorlie laboratories in September 2023. |

Section 2 Reporting of Exploration Results from Bungarra, Stirling, Hurleys, Neptune and Boundary Prospects
(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 obtaining a licence to operate in the area. |
• The Bullseye Gold Prospects are 100% held by Bullseye Mining Limited (EMR~78.05%). 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, Deep Yellow NL and Korab Resources Ltd. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• Geology comprises a basalt country rock and BIF. The Neptune and Boundary prospects are 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: - 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 results are shown in Appendix One. |
| 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 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 |
• All reported intersections are down hole lengths. True widths are unknown and vary depending on the orientation of target structures. |

| 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 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 contaminating substances. |
• 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 commercially sensitive. |
• Additional drilling programs are being planned across all exploration licences. |

Aspects of the determination of mineralisation that are Material to the Public Report.
-
Diamond core was sampled using half-core where the core is cut in half down the longitudinal axis and sample intervals were determined by the geologist based on lithological contacts, with 80% of the sample intervals being 1 metre in length. In areas of no mineralised (negligible amounts of alteration/sulphides typically present with mineralisation) a 2m composite was submitted.
-
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.
-
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. Multielement 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. The "Okvau Close Spaced” Drilling was carried out by the he Okvau Mine Site laboratory using Aqua Regia digest with a AAS finish.

JORC Code explanation | Commentary |
• Historical drilling results in this ASX release refer to historical drilling records from OZ minerals completed in 2010. Historical RC drilling samples were through a cyclone on a 1 metre basis. The specific sub-sampling equipment utilised is not known and therefore representivity is not known. • Soil samples (approximately 1000g) are collected to avoid any surface contamination from shallow (generally +/-20-30cm deep) shovel holes to selectively sample pisolite bearing laterite soil material and are used to define areas of interest and mineralised system footprints. • Soil auger samples (approx. 500g) are collected from hand auger refusal depth in in-situ weathered bedrock (B/C horizon soil transition). The sample is sieved to collect a sample passing 2mm. Where transported material is not penetrated no sample is taken to avoid spurious anomalism in transported material and assist in confirming bedrock geology. This sampling is preferred to constrain areas of interest and/or drill targets. • Soil sample preparation is carried out at a commercial off-site laboratory (ALS Phnom Penh). Gold and multi- element assays are conducted at ALS Brisbane, Australia utilising a 50gram subsample of 85% passing 75µm pulped sample digested by Aqua Regia and analysed by ICP-MS. • Rock chip samples are collected as niche samples of rock material of specific style or character of interest. A target sample weight of 3-5kg is collected for assay. Sample 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, Brisbane, Australia utilising a 4 acid digest of a 1g subsample of 85% passing 75µm pulped sample and determination by ICP-AES or ICP-MS for lowest available detection for the respective element. • Oxide matrix standards, field duplicates and pulp blanks are inserted in sample batches to test laboratory performance. |

| 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 UDR650 rig is used to drill 5.5-inch RC precollar holes and a LF90 rig is used to drill NQ2 Diamond Core. The ”Okvau Close Spaced” drilling was completed using aA Schramm T450WS/BH mounted on tracked drill rig is used to drill 5.51-inch. • 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 were within acceptable limits. |
| 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. • The drilling results relate to historical sampling results. Drill recoveries are not known. |
| 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. |
• All RC chips and diamond core is routinely logged (qualitatively) by a geologist, to record details of 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 sampling sites. • Emerald cannot verify the detail and full scope of the historical logging from the available reports. |
|
| 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 being sampled. |
• Most samples are dry and there is no likelihood of compromised results due to moisture. • All samples except for the “Okvau Close Spaced” drilling 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 standard and is deemed appropriate for the material. • The Okvau Mine site lab is not accredited. • The historical data available to Emerald is such that Emerald cannot reliably confirm that the historical RC samples were dry and free of free of significant contamination. Emerald cannot specifically confirm that the RC drilling results have not been compromised due to excessive moisture of contamination. • The historical data available is such that Emerald cannot reliably confirm the specific subsampling techniques and sample preparation used to generate samples to be sent for assay. It is not known whether a subsample was retained as a geological record. • No review of historic sampling practices has been completed nor was possible from the data available to Emerald for this announcement. |
| 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, spectrometres, handheld XRF instruments, etc, the parametres 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. • Drill samples for the historical results followed the above assaying methodology except the sample preparation occurred in the ALS Laboratory in Vientiane, Laos. • Samples processed at the Okvau Mine Site laboratory (Okvau Close Spaced Drill samples) were analysed using Aqua Regia digest with a AAS finish. |
| 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 in place. |

• Historical sampling and assay verification processes are unknown. • No sample recording procedures are known for reported data from historic drilling. |
||
| 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. |
• 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 IND60 or WGS84 as specified in Appendix Three. • 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). • The newly reported collars of holes drilled have been picked up by a licenced surveyor with DGPS equipment. • 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 by the 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. • Soil sampling grids are of appropriate orientation to cover the observed mineralisation. |
| 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 laboratory in Phnom Penh. • No information is available regarding sample security procedures for the historical drilling results reported. • All samples processed at the Okvau Mine site (Okvau Close Spaced Drill Samples), are handled by RNS employees and utilise the same stringent internal paperwork and tracking systems as the routine grade control methodology. |
| 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 and Vientiane facilities in October 2023. • No review has been completed due to data availability for historical drilling. • Due to the critical importance to production, the Okvau Mine site lab has regular internal audits completed. Including routine checks of selected assays being sent to external laboratories for umpire checks. |
Section 2 Reporting of Exploration Results from New Significant Intercepts Okvau Drill Programs
(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 obtaining a licence to operate in the area. |
• The Okvau and Memot licences are held (100%) in the name of Renaissance Minerals (Cambodia) Limited which is a wholly owned subsidiary of Emerald Resources NL (EMR). EMR are in a Joint Venture agreement on the Antrong North and South Licences where the Company and earn up to a 80% share. • 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 Three. |
| 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. |
• No high grade top cuts have been applied. The reported significant intersections in Appendix Three are above 2 gram metre Au intersections and allow for up to 4m of internal dilution with a lower cut trigger values of greater than 0.5g/t Au. Cu significant intersections allow for up to 4m of internal dilution with a lower cut trigger values of greater than 2,000ppm Cu. |

Explanation | Commentary |
| • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
||
| 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 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. |
• 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 commercially sensitive. |
• Further drilling programs are being planned on additional nearby targets. • Additional drilling programs are being planned across all exploration licences. |
