Okvau Grade Control Progress
During the Quarter, the Company continued to progress a circa 17,600m (2,448m September Quarter) grade control programme of the near and at surface oxide mineralisation at Okvau. Whilst the results of the direct comparison to reserve are still being assessed, the grade control defined mineralisation has notably expanded, well past the expected reserve blocks for the same area tested. Figure Thirty Three illustrates the pictorial comparison of grade control defined mineralisation compared to reserve.
Figure Thirty Three | Near Surface Grade Control to Reserve Comparison
==> picture [379 x 271] intentionally omitted <==
Page 7 of 21
==> picture [137 x 33] intentionally omitted <==
The discovery of additional mineralisation outside the current reserve blocks in the near surface oxide material has likely been caused by a combination of natural processes, such as supergene enrichment and the flattening of mineralised structures during the oxidation processes and the relocation of surface material by historical, artisanal mining activities. The work highlights the conservative treatment of the near surface ore reserve estimate.
Environment and Social
The Environmental Management System for the Okvau Gold Project is well developed and has been substantially implemented throughout the construction phase of the Project. An Environmental Compliance Register of all ESIA and Management Plan commitments, monitoring and mitigation actions, are being continually reviewed and maintained. A comprehensive Monitoring Programme is fully implemented as part of implementing the Okvau’s extensive Environmental and Social Management and Monitoring Plan.
The Biodiversity Offset Management Plan is being implemented in offset sites within the Phnom Prich Wildlife Sanctuary (PPWS). During this Quarter, 1,324 of the locally endangered Afzelia xylocarpa, or “Beng” tree species, were planted in two offset sites, concentrating alongside the new access road. To date, 2,324 trees have been planted in offset sites, 322 trees at Okvau rehabilitation sites and over 900 trees have been planted around schools, community and government sites and roadsides. A key target for the offset sites is to achieve a 10 times net gain in Afzelia xylocarpa trees and a 5% net gain in quality hectares.
The Company is continuing to support its School Nursery Project across four local schools. Schools spend earnings on educational tools, supplies, classroom upgrades and sporting equipment. The Company is investigating expanding the programme.
In support of the biodiversity offset programme, and to help protect the PPWS, a fully funded and equipped Ranger Hut has been constructed by the Company along the access road. Eight fully-funded rangers on rotation occupy the Hut and patrol nearby areas and offset sites full-time. The Company has established a close working partnership with the local wildlife rangers and will continue to support ranger’s efforts to prevent forest crimes.
The Environmental and Social Impact Assessment for the Okvau Gold Project was finalised in July 2017 (ESIA) and approved by the Ministry of Environment (MoE) in November 2017. Emerald is committed to targeting strict compliance with corporate governance, international guidelines and Cambodian Law. The Company has transferred the first tranche of a staged third party bond for the environmental bond and contributed significant funds to the Environmental, Social and Endowment funds in accordance with its environmental obligations. These funds and other programmes implemented by the Company seek to achieve a net-gain in both biodiversity and social values.
Emerald progressively rehabilitates both its mining and exploration projects. All non-active exploration drilling sites have been rehabilitated with bags and rubbish removed, spoils buried, collars cut and plugged and topsoil spread back over the disturbed area. Beng trees are planted inside the Okvau project development area, when available.

Snoul
During the Quarter, the Company completed a 33 collars RC drill programme (1,673m) on the Anchor Prospect located within the Snoul Licence. The preliminary reconnaissance drill programme targeted the existing significant intersections in historical drilling (refer announcement on 13 July 2017) and a gold-in-soil anomaly 1km along strike from the existing historical results.
The drill programme confirmed and extended the historic results (including 6m @ 8.28g/t from 12m and 3m @ 6.43g/t from 6m) with significant intersections such as 5m @ 6.23g/t from 14m, 8m @ 1.37g/t from 34m and 3m @ 2.67g/t from 24m.
The drill results show encouraging anomalous results from the previously untested northern portion of the Anchor Prospect gold-in-soil anomaly including 1m @ 2.85g/t from 3m, 1m @ 1.41g/t from 53m, 1m @ 1.32g/t from 38m (refer drill results in Appendix 1).

O’Kthung
During the Quarter, the previously reported significant gold-in-soil anomaly (recently named the O’Kapai prospect) on the O’Kthung licence (refer announcement on 27 July 2020) was infilled with 274 Auger soils to a 100m x 200m grid to better delineate the anomaly. The peak results returned include 1530, 1040, 468, 288, 217 ppb Au. The two highest Auger results (1.53 and 1.04 g/t Au) are proximal to a Diorite/Hornfels contact on the southern margin of a mapped felsic intrusive unit.

Koan Nheak
As announced on 8 September 2020, following a comprehensive strategic review of the Company’s regional licences, the Company has withdrawn from the joint venture with Angkor Gold Cambodia, in which it was to earn an 80% interest in the Koan Nheak Project. The Company awaits official confirmation from the Cambodian Minister for Mines acknowledging the withdrawal.
Svay Chras
The Company also advised the Minister for Mines Cambodia that it has relinquished its ownership of the 100% owned Svay Chras tenement area after completing a comprehensive surface geochemical sampling programme, with little to no anomalism defined. The Company awaits official confirmation from the Cambodian Minister for Mines acknowledging the relinquishment.
Other Exploration
The Company has continued to seek to expand on its prospective tenure in Cambodia, by making further applications for licences in country, and has advanced discussions with third parties in that regard. The Company continues to assess additional prospective gold development opportunities both in Australia and internationally with the aim to create a multi asset gold producing company.
Corporate
Cash Position
Emerald’s consolidated cash at 30 September 2020 was approximately A$109 million. Of the A$109 million of funds on hand, A$67 million remains in a controlled account and will be available for development expenditure in US$10 million tranches upon development continuing in accordance with the project schedule and budget.
The Okvau Project finance facility has also provided access to a US$100 million Acquisition and Development Facility to fund future development and acquisition opportunities as previously announced on 26 June 2019. Emerald is excited to work with Sprott with the aim to grow the Company through the procurement of value adding assets for subsequent developments to create a multi asset gold producing company.
In accordance with ASX Listing Rule 5.3.5 the Company advises that payments made to related parties and their associates during the period included director fees, salaries and superannuation ($179k), rental payments to a director related party for the Company premises ($50k) and payments to a director related party for the provision of company secretarial services ($15k).
COVID-19 Update
The Company has implemented suitable protocols to minimise the potential transmission of COVID-19 as the health and wellbeing of the Company’s staff, contractors and stakeholders continues to be focussed upon. Renaissance Safety Manager, Construction Manager, Civil Works Supervisor, Operations Manager, in addition to EMR’s COO Executive Director, were all based on site during the Quarter to maintain awareness and ensure these protocols are adhered to while advancing construction activities.
To date, the Company has completed 3,877 screens to monitor daily temperature checks of all employees, contractors and visitors across five locations on site with no reported cases.
The Company is continuing to monitor this fluid situation and the operational challenges the Company may face in terms of access to human resources as well as to the Company’s project development supply chains. Uncertainties around international freight pose an ongoing concern to project development but have been considered in the development timeline and are expected to ease in the coming months. The Company maintains its forecast for commissioning of and the first gold production from the Okvau Gold Project in Q2 2021. The Company will provide further updates accordingly.
There were no serious incidents or injuries during the Quarter.

Cambodian Gold Project
Summary
Emerald’s main focus is the exploration and development of its Cambodian Gold Projects which comprise of a combination of 100% owned granted licences, applications and earn-in & joint venture agreements covering a combined area of 1,132 km². The 100% owned Okvau Gold Project (‘Okvau Gold Project’) is the Company’s most advanced project which is located approximately 275 kilometres north-east of Cambodia’s capital city of Phnom Penh in the province of Mondulkiri (refer Figures 40 and 41). The town of Kratie is located on the Mekong River approximately 90 kilometres to the west and the capital of Mondulkiri, Saen Monourom is located approximately 60 kilometres to the south-east. In May 2017, Emerald completed a Definitive Feasibility Study (‘DFS’) on the development of the Okvau Gold Project which demonstrated a robust project producing approximately 106,000 ounces of gold per annum on average over 7+ years from a single open pit.
In July 2018, the Company was granted the Industrial Mining Licence covering 11.5 km² which allows for the development of the Okvau Gold Project. The Mining Licence has an initial 15-year period with the right to two renewals of up to 10years for each renewal in accordance with Cambodian laws. The grant of the Mining Licence followed approval of the Okvau Gold Project by the Office of Council Ministers for both the rezoning of the project area to ‘Sustainable Use’ within the Phnom Prich Wildlife Sanctuary (‘PPWS’) and the granting of the Mining Licence. The rezoning of the Mining Licence area to ‘Sustainable Use’ lawfully permits commercial development under Cambodian law and follows the successful negotiation and approval by the Minister of Environment (‘MoE’) of the environmental contract (the ‘Environmental Contract’) and environmental licence (‘Environmental Licence’) in December 2017.
The Company has successfully completed the resettlement of 62 local families and site works to remove abandoned structures away from the Okvau Mining Licence area. Emerald has completed the installation of a security fence around the Project Development Area (“PDA”) to ensure the safety of personnel, visitors and wildlife. Construction of a 35 tonne bridge across the Prek Te River has now been completed with substantial completion of upgrades to the existing 50km of dirt roads and current finalisation of the construction of 14km of new road to site which will allow for all year continuous access to the Okvau site.
Topography of the tenure area is relatively flat with low relief of 80 metres to 200 metres above sea level. The Okvau Deposit and other gold occurrences within the tenure are directly associated with diorite and granodiorite intrusions and are best classed as Intrusive Related Gold mineralisation. Exploration to date has demonstrated the potential for large scale gold deposits with the geology and geochemistry analogous to other world class Intrusive Related Gold districts, in particular the Tintina Gold Belt in Alaska (Donlin Creek 38Moz, Pogo 6Moz, Fort Knox 10Moz, Livengood 20Moz).
In December 2019 the Mineral Investment Agreement (‘MIA’) was signed which provides certainty and stability of the fiscal regime for the development and operations of the Okvau Gold Project. Following confirmation of the key fiscal incentives of the MIA, the key assumptions and inputs of the DFS were reviewed resulting in a significant improvement in the NPV and IRR of the Project.

| ( | Criteria in this section apply to all succeeding sections). | 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. |
• Historical drilling results in this ASX release refer to historical drilling records from Mekong Minerals Ltd and Southern Gold Ltd. • Historical diamond drilling sampling was conducted on intervals determined by the geologist at the time corresponding to visually interpreted mineralised intervals at the time of sampling. No specific information is available for the sub sampling methodology used to generate samples for laboratory submission. Retention of sample as a geological record cannot be verified. • 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. • Emerald undertook field investigations to confirm collar locations and evidence of work areas on the Snoul Project where possible. The findings of this field investigation corresponded well with the reported works. • 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. • Oxide and Fresh standards, field duplicates and pulp blanks are inserted in sample batches to test laboratory performance. • 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. |

other type, whether core is oriented and if so, by what method, etc). |
Mines and Energy Department. The diamond core hole and RC hole diameter is unknown. • The historic diamond core was orientated but the specific technique is unknown. • A track mounted UDR650 multipurpose drill rig is used to drill 5.5-inch RC 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. |
• The drilling results relate to historical sampling results. Drill recoveries are not known. • It is not possible to confirm the relationship between sample recovery and grade. • 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 usuallydry. |
| 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 was routinely logged (qualitatively) by a geologist. 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 soils samples are dry and there is no likelihood of compromised results due to moisture. • All soil samples are 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 Renaissance, numerous times and most recently by Mr Keith King Jan 2020. Samples are dried for a minimum of 12 hours at 105˚C. • Soil samples are split to <3kg and pulverized in an Essa LM5 Ring Mill. A standard >85% pass rate is achieved (with particle size analysis performed on every tenth sample as a check). • This sample technique is industry norm and is deemed appropriate for the material. • Field duplicates of soil samples are also collected routinely (approx. 1 every 20 samples) • This sample technique is industry norm and is deemed appropriate for the material. • 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, 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 soil samples are sent to the NATA accredited ALS Laboratory in Vientiane, Laos, for single Aqua Regia digest with a 50g charge with a 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 • ME-MS44 method has a lower detection limit of 1ppb gold. • All magnetic susceptibility measurements of soil samples are made with a Terraplus KT-10 magnetic susceptibility meter. • 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 QA/QC data and control charts of standard, replicate and duplicate assay results, are communicated electronically. • Drill samples for the historical results were sent to laboratories including McPhar Geoservices (Philippines), ALS (Lao) and Intertek (China and Philippines). The specific assay methods and specific assay laboratories used for the specific drill samples is not known. • Adherence to appropriate sample preparation and analytical quality control programmes cannot be verified. Adherence to industry standard QAQC protocols for the historical sampling and assays cannot be verified. |
| 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. • Historical sampling and assay verification processes are unknown. • No sample recording procedures are known for reported data from historic drilling. The historical data was supplied data is in pdf and Microsoft access format. Data is currently being migrated to Emerald’s database. |
| 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. |
• All sample locations are first surveyed with a hand- held GPS instrument (which generates relatively inaccurate RL values). All locations are surveyed to the WGS84 48N UTM grid. • 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). • Survey methods for historic drilling are unreported and Emerald intends to complete handheld GPS survey pick up for historic drilling where collars can be located to verifythe surveyaccuracy. |
| Data spacing and distribution |
• Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree ofgeological and |
• The reported soil sampling data is in no way sufficient to establish mineral resources estimates. |

grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. |
• Given the early stage of exploration there is no regular drill spacing. • Current drill spacing is inadequate to establish geological and grade continuity required for estimation of resources. • No compositinghas 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. |
• Soil sampling grids are of appropriate orientation to cover the observed mineralisation. • Due to the early stage of exploration, determination of true widths and definition of mineralised directions encountered in drilling is not always possible. • Drilling has been done at various orientations. • The risk of significant sampling orientation bias is not known at this time. |
| Sample security | • The measures taken to ensure sample security. |
• The chain of custody for all soil samples from the sample site to the ALS Sample Preparation facility in Phnom Penh is managed by Renaissance personnel. Soil samples are transported from the sample site to the Okvau field camp, 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 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 Vientiane except for samples from the first 9 drill holes, which were submitted to Mineral Assay and Services Co in Thailand. • No information is available regarding sample security procedures for the historical drilling results reported. |
| 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. • No review has been completed due to data availabilityfor historical drilling. |

• The licences are held (100%) in the name of Renaissance Minerals (Cambodia) Limited which is a wholly owned subsidiary of Emerald Resources NL. • The Snoul Exploration Licence is held in the name of Mekong Minerals (Cambodia) Limited • Emerald has entered into a joint venture agreement with Mekong Minerals to earn up to 70% interest in the Snoul Project. • 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; Angkor Gold, Mekong Minerals Ltd and Southern Gold Ltd 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 results are shown in Appendix One of the ASX announcement dated 13 July 2017. • 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 clearlystated. |
• No high grade top cuts have been applied. • All results reported are gold only. • A summary of all drilling results and details are shown in Appendix One of the ASX announcement dated 13 July 2017. • Only intercepts with a minimum width of 1 metres at a 0.5g/t gold cut-off are considered significant and reported in Appendix One of the ASX announcement dated 13 July 2017. |
| 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 misleadingreportingof Exploration Results. |
• Soil and Rock chip geochemical anomalies are depicted on the attached maps with sample points locations denoted and auger and rock chipsymbols coloured by gold levels. |
