1,000m infill RC drill program approved for Gecko-Goanna to follow up recent high grade copper mineralisation intersected in pre-collar to deep drill hole GODD032
Mauretania
Emmerson Resources Limited (“Emmerson”, ASX: ERM) is pleased to announce the recommencement of drilling at Mauretania (Figure 1) following the successful three hole maiden program (refer ASX announcement of 12 October 2015).
The planned 18 hole RC program is primarily designed to test the extent of shallow supergene mineralisation, similar to that at the former Nobles Nob mine which produced over 1.1 million ounces of gold at an average recovered grade of 17.3g/t Au from a small footprint of ~200m in strike extent and within 100m of the surface.

Individual 1 metre assay results (re-splits) from the maiden reverse circulation (RC) program have now been received and have enhanced the previously reported 3 metre composite results in both the primary and supergene zones. The revised intersections are presented in Figures 2 & 3 and summarised in Tables 1 & 2.
Gecko-Goanna
Immediately following the Mauretania program, 4 RC drill holes for 1,000m will be completed at Gecko-Goanna aimed at testing the continuity of the shallow, high grade copper mineralisation intersected in the pre-collar to deep drill diamond hole GODD032 (refer to ASX announcement of 19 August, 2015). The style of copper mineralisation intersected in the pre-collar is considered analogous to that at Goanna, located some 800m to the east, and has the potential to greatly expand the existing Mineral Resource (Figure 4, Table 3)
Examination of the deeper portions of drill hole GODD032 continue where multiple zones of copper and bismuth mineralisation were intersected associated with carbonate-chlorite-sericite and jasper alteration. The best intersection recorded was 0.8m at 1.7% Cu, 29ppb Au and 134ppm Bi from 1,175m. Of particular interest is a zone of quartz–dolomite and hematite-quartz-jasper breccia with minor ironstone from a down hole depth of 1175m, indicative of spent hydrothermal fluids on the periphery of mineralisation. Subsequent work has included down hole seismic and 3-component magnetics. Pending receipt of the down hole magnetic models and further analysis of the drill core, the refined seismic model indicates that GODD032 was not drilled in the optimal position with respect to the alteration and potential mineralisation.

About Tennant Creek and Emmerson Resources
The Tennant Creek Mineral Field (TCMF) is one of Australia’s highest grade gold and copper fields producing over 5.5 Mozs of gold and 470,000 tonnes of copper from a variety of deposits including Gecko, Orlando, Warrego, White Devil, Chariot and Golden Forty, all of which are within Emmerson Resources (ASX: ERM) exploration and joint venture portfolio. These deposits are considered to be highly valuable exploration targets and, utilising modern exploration techniques, Emmerson has been successful in discovering copper and gold mineralisation at Goanna and Monitor in late 2011, the first discoveries in the TCMF for over a decade. To date, Emmerson has only covered 5.5% of the total tenement package (in area) with these innovative exploration techniques and is confident that, with further exploration, more such discoveries will be made.

==> picture [595 x 45] intentionally omitted <==
Emmerson holds 2,500km[2] of ground in the TCMF, owns the only gold mill in the region and holds a substantial geological database plus extensive infrastructure and equipment. Emmerson has consolidated 95% of the highly prospective TCMF where only 8% of the historical drilling has penetrated below 150m.
Emmerson is led by a board and management group of experienced Australian mining executives including former MIM and WMC mining executive Andrew McIlwain as non-executive chairman, and former senior BHP Billiton and WMC executive Rob Bills as Managing Director and CEO.
Pursuant to the Farm-in agreement entered into with Evolution Mining Limited (Evolution) on 11 June 2014, Evolution is continuing to sole fund exploration expenditure of $15 million over three years to earn a 65% interest (Stage 1 Farm-in) in Emmerson’s tenement holdings in the TCMF. An option to spend a further $10 million minimum, sole funded by Evolution over two years following the Stage 1 Farm-in, would enable Evolution to earn an additional 10% (Stage 2 Farm-in) of the tenement holdings. Evolution must spend a minimum of $7.5 million on exploration, or pay Emmerson the balance in cash, before it can terminate the farm-in. Emmerson is acting as manager during the Stage 1 Farm-in and is receiving a management fee during this period. Exploration expenditure attributable to the Stage 1 Farm-in to date is approximately $6.5 million.

SECTION 1.1 SAMPLING TECHNIQUES AND DATA – MAURETANIA PROJECT AREA – RC 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 downhole 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 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
The_Mauretania and Sunrise Project_holes were sampled using Reverse Circulation drilling techniques (RC).Six holes (MTRC001-006 for 1,054m) including one abandoned (54m) were drilled in the Mauretania area, two holes (MTRC007-008 for 260m) were drilled in the Black Cat Project and two holes (SNRC001-002 for 254m) were drilled into the Sunrise Project. Drill holes targeted ironstone and magnetic targets. These were single hole tests apart from MTRC004-006 which were drilled on 50m centres. Holes were been angled to optimally test the interpreted shear zones/geophysical model). Typically, most drill holes have been drilled at an angle between 60 – 70 degrees). RC chips are riffle split on site to obtain 3m composite samples from which 2.5 – 3.0kg was pulverised (at Genalysis in Alice Springs) to produce a 25g charge for analysis by Aqua Regia digestion / ICP-MS/OES (Au, Ag, Bi, Cu, Fe, Pb, Zn, Mo, U, Se, Sb). Individual 1m (re-split) samples are retained on the drill site and anomalous zones were individually assayed (re- splits) once 3m composite results are returned. Individual 1m samples are pulverised to produce a 25g charge for analysis by four acid digest with an ICP/OES (Cu, Fe, Pb, Zn) ICP/MS (Ag, Bi, Mo, Se, Sb, U) & Fire Assay/AAS (Au) finish. RC samples were collected via a fixed cone splitter that is mounted to the drill rig under a 1200cfm cyclone. The fixed cone splitter has three sample chutes for comparative sampling, 2 chutes are synchronised for comparative samples and 1 Chute is independently set for thegeologists field samples. |
| 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, by what method, etc). |
RC drilling accounts for 100% of the current reported drilling at_Mauretania Project Area_and comprises, 3m riffle split, composite RC samples, and 1m riffle split RC intervals (re-splits). RC drilling utilizes a 4.5 inch, face sampling bit. Drill hole depths range from 100m to 322m. RC recoveries are logged and recorded in the database. Overall RC recoveries are >90% for the Mauretania Project, and there are no significant sample recovery problems. |
| 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 samples are visually checked for recovery, moisture and contamination. Any issues or concerns are discussed at the time with the drilling contractor and also recorded in our database. Recoveries are considered good for the reported RC drilling. RC samples are collected via a fixed cone splitter that is mounted to the drill rig under a 1200cfm cyclone. The cyclone and splitter are routinely cleaned with more attention spent during the drilling of damp or wet samples. It was rare to experience more than 2 sequential “wet samples” duringthisprogram. |

|---|---|---|
| Emmerson do not consider that there is evidence for sample bias that may have occurred due to preferential loss/gain of fine/coarse material. |
||
| 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. |
Standard operating procedures are employed by Emmerson for logging RC samples. All RC samples are lithologically logged in one metre intervals. Drill hole logging data is directly entered into field tough book computers via Logchief software. Look up codes and real time validations reduce the risk of data entry mistakes. Field computer data (the drill log) are uploaded to Emmerson’s relational database whereby the data undergoes a further set of validations checks prior to final upload. Standardised codes are used for lithology, oxidation, alteration, veining and presence of sulphide minerals. Structural logging of the RC drill samples was not possible. Magnetic susceptibility data for all individual 1m RC samples are collected as per ERM procedure. All RC chips are stored in trays in 1m intervals. Representative RC chips and diamond core is available to all geologists (a physical reference set) to ensure consistency of logging. |
| 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. |
Standard sampling operating procedures have used by ERM at Mauretania Project area drilling for RC samples. The sample preparation of RC samples for follows industry best practice in sample preparation involving oven drying, coarse crushing of the sample down to ~10mm followed by pulverisation of the entire sample (total prep) using LM5 grinding mills to a grind size of 85% passing 75 micron. Pulverised material not required by the laboratory (pulps) including duplicate samples are returned to ERM, logged into a database and stored undercover at the Tennant Creek office. Coarse rejects are disposed of by the Laboratory. RC samples were collected on the rig using cone (from the drill rig) and then riffle split by the field assistants if dry to obtain a 3 kg sample. If samples are wet, they are left to dry before being riffle split. |
| 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. |
Field QC procedures involve the use of certified reference material (CRM’s) as assay standards, and ERM include blanks, duplicates. QAQC protocols consist of the insertion of blanks at a rate of one in every 40 samples, insertion of standards (CRM’s) at a rate of approximately one in every 20 samples and duplicate field sample analysis of at a rate of approximately one in every 20 samples. A selection of CRM’s is available to the geologists and insertion points are predetermined prior to drilling. The geologist has the ability to override this predetermined insertion based on visual and geological characteristics of the current drill hole. Insertion of assay blanks is increased when visual mineralisation is encountered and consists of insertion above and below the mineralised zone. Samples typically weigh less than 3kg to ensure total preparation at thepulverisation stage. |

| RC field duplicates are collected on the 3m composites samples, using a riffle splitter. Individual 1m RC sample duplicates (re-splits) are also collected using the same technique. Laboratory checks include CRM’s and/or in-house controls, blanks, splits, and replicates that are analysed with each batch of samples submitted. These QC results are reported along with sample values in the final analytical report. Barren quartz washes are also routinely used in zones of mineralisation. QAQC data is uploaded with the sample values into ERM’s database through an external database administrator (contractor). A QAQC database is created as a separate table in the database and includes all field and internal laboratory QC samples. QC data is reported through a series of control charts for analysis and interpretation by the Exploration Manager or his/her delegate. The sample sizes are considered to be appropriate to correctly represent the sulphide mineralisation at_The_ _Mauretania Project_based on the style of mineralisation (iron oxide copper gold), the thickness and mineral consistency of the intersection(s). Emmerson’s sampling methodology (SOP) is available at any timeforpeer review. |
||
| 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. |
The Exploration Manager of ERM has visually verified significant intersections in RC samples. The geochemical data is managed by ERM using and external database administrator and secured through a relational database (Datashed). Laboratory data is been received in digital format and uploaded directly to the database. Original data sheets and files are been retained and are used to validate the contents of the database against the original logging.

Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
RC Drill hole collars were surveyed (set out and pick up) using a differential GPS and by a suitably qualified company employee. Collar survey accuracy is +/- 30 mm for easting, northing and elevation coordinates. Co-ordinate system GDA_94, Zone 53. Topographic measurements are collected from the final survey drill hole pick up. Downhole survey measurements were collected at a minimum of every 30m using an REFLEX EZ-Shot® electronic single shot camera for RC. This survey camera equipment is quoted by the manufacturer to have an accuracy of o Azimuth 0-360º ± 0.5ºo Dip ± 90º ± 0.2º If the measurement is considered to be affected by magnetic material (ironstone) then an average from the last non affected and the next non affected measurement is used. There were no down hole survey issues during this drill program. |

50m x 50m. There is insufficient drill / assay data to establish the geological and grade continuity at this early stage of drilling. No Mineral Resource estimation can be applied to these Exploration Results. Exploration Results in this report are based on Individual 1m samples (re-splits) from anomalous zones returned from the 3m composite assay results and reported to the ASX on the 12/10/2015. |
| 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. |
Exploration drilling is perpendicular to the interpreted strike of the Mauretania targets. No orientation based sampling bias has been identified in the data at this point. Results at this stage suggest that the geological and geophysical targets being tested have been drilled in the correct orientation. |
| Sample security |
The measures taken to ensure sample security. | Samples are selected, bagged and labelled by site geologist. They are placed in sealed polyweave bags and then larger bulka bags for transport to the assay laboratory. The assay laboratory confirms that all samples have been received and that no damage has occurred during transport. Tracking is available through the internet and designed by the Laboratory for ERM to track the progress of batches of samples. Sample receipt is logged into ERM’s sample ledger. While samples are being processed in the Lab they are considered to be secure. |
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. |
An internal review of the sampling techniques, QAQC protocols and data collection was conducted by Emmerson in November 2013. Optiro (2013) also reviewed the standard operating procedures for RC and diamond core sampling used and discussion with the site geologist confirmed that these were understood and beingfollowed. |

| Drillhole information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes: o easting and northing of the drillhole collaro elevation or RL of the drillhole collaro dip and azimuth of the holeo downhole length and interception deptho hole length. |
A list of the drillholes and the drillhole collar locations and elevation, the total depth, drill type and dip and azimuth is included as a Table in the body of the text. |
| 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. |
Mineralized intersections are reported as down hole intervals and not weighted averages. (RC only). Please refer to the table of significant results in the body of the text for detail on cut off grades and mineralised widths. These results are exploration results only and no allowance is made for recovery losses that may occur should mining eventually result, nor metallurgical flow sheet considerations. |
| Relationship between mineralization 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 drillhole angle is known, its nature should be reported. If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (eg ‘downhole length, true width not known’). |
Mineralisation identified at the_Mauretania Buried_ Magnetic Target(MTRC004 – 006) is contained within hematite-quartz jasper ironstone which grades with depth to a hematite-magnetite ironstone (see cross – section in the text). The ironstone dips 75 degrees to the southwest and strikes NNW-SSE. Magnetic modelling suggests the ironstone has a strike length of 120m and the modelled body plunges to the northwest. The three RC holes testing this model (MTRC004- 006) are 50m apart and are inclined at -70 degrees to the northeast to allow intersection angles with the mineralised zones approximate to the true width. The RC holes at Sunrise (SNRC001-002) are perpendicular to the East-West striking surface ironstone outcrop. The holes are inclined -70 degrees to the North making the intercepts approximate to true width. |
| 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 |

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. |
Geophysical magnetic susceptibility logging is completed at 1m intervals on site (RC drilling). Three component magnetic probing of (MTRC001, 002, 005, 007, 008 and SNRC001-002) has been completed. A regional RAB program was run concurrently with the RC drilling and is detailed in a separate JORC Table. |

SECTION 1.1 SAMPLING TECHNIQUES AND DATA – MAURETANIA PROJECT AREA - REGIONAL RAB 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 downhole 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 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
Rotary Air Blast (RAB) samples were composited at the drill site into 4m samples via spear (tube) sampling. These 4m RAB composite samples from which 2.5 – 3.0kg was pulverised (at the laboratory-Genalysis) to produce a 25g charge for analysis by Aqua Regia digestion (Au, Ag, Bi, Cu, U, Pb, Zn, Mo, Se, Sb and Fe). A 1m bottom of hole RAB sample for each hole was also collected and dispatched for Four-Acid Digest comprehensive multi-element analysis (46 elements plus gold). A reprehensive bottom of hole chip sample was also retained in labelled chip trays for reference and dispatched for ASD analysis in Queensland (Evolution mine site). |
| 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, by what method, etc). |
RAB drilling accounts for 100% of the Mauretania regional drilling. RAB drill hole spacing was of a regional nature and completed on nominal 80m centres along drill lines spaced 200 – 400m apart and oriented NNE-SSW and also ESE-WNW (see figures in text). 158 angled RAB holes were completed for a total of 6,956 and 1,926 samples dispatched. The deepest RAB hole was 92m and the shallowest 24m with the average hole depth for the program being 44m in the Mauretania Project Area All RAB holes were angled at 60 degrees to the NNE or ESE. Holes and drill lines were designed to optimally test the mineralised shear zones which typically strike east-west and dip steeply to the south. RAB drilling utilises a 4 inch blade bit. Approximately 20% of drilling was completed using a RAB hammer to obtain a reliable bedrock sample. |
| 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. |
Overall recoveries are for the Mauretania RAB drilling is considered good and there were no obvious sample loss issues. All RAB samples were dry. No voids were experienced during RAB drilling. Emmerson do not consider that there is evidence for sample bias that may have occurred due to preferential loss/gain of fine/coarse material during the Mauretania regional drillprogram. |
| 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 RAB holes were logged by an Emmerson geologist on site during the 2015 drill program. Logged data was then uploaded to Emmerson’s relational database – Datashed. |

| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length and percentage of the relevant intersections logged. |
RAB logging intervals are 1m increments and the entire hole was logged. Selected RAB chips are stored in chip trays in 1m intervals, however due to age some are considered to be in poor condition. |
|
| 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. |
RAB samples were composited at the drill site into 4m samples via spear (tube) sampling. These 4m RAB composite samples typically weighted from which 2.5 – 3.0kg. A 1m bottom of hole RAB sample for each hole was also collected via spear / tube sampling technique. The sample preparation of samples from the regional Mauretania RAB drill program follow industry best practice. Sample preparation involved oven drying, coarse crushing of sample down to ~10mm followed by dry pulverisation of the entire sample (total prep) using LM5 grinding mills to a grind size of 85% passing 75 micron. Pulverised material not required by the laboratory (pulps) including duplicate samples were returned to Emmerson Resources and are stored in Tennant Creek. Coarse rejects are disposed of by the Laboratory. All RAB samples were dry when submitted to the Laboratory. |
| 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. |
Field QC procedures are routinely undertaken by Emmerson and involve the use of representative certified reference materials (CRM’s) as assay standards, and include blanks and duplicates. QAQC protocols consisted of the insertion of blanks at a rate of approximately one in every 40 samples, insertion of standards at a rate of approximately one in every 20 samples and duplicate field sample analysis of at a rate of approximately one in every 20 samples. The geologist on the rig is responsible for maintaining the field QC. Insertion of assay blanks was increased when visual mineralisation was encountered and consists of insertion above and below the mineralised zone. Internal Laboratory checks were also included as in- house controls, blanks, splits, and replicates that are analysed with each batch of samples submitted. These QC results are reported along with sample values in the final analytical report. Intertek Genalysis conducted the analytical analysis. Sample preparation occurred in Alice Springs, Northern Territory and analyses were read in Perth, Western Australia. Review of QC results were conducted through a series of control charts and are considered satisfactory to good. The sample sizes are considered to be appropriate to correctly represent the style of mineralisation - Iron oxide coppergold. |

Collar survey accuracy is +/- 5 metres for easting, northing and elevation coordinates. Co-ordinate system GDA_94, Zone 53. Topography control is considered as satisfactory. The area is typically very flat. No down hole surveying was conducted on the RAB holes and it is assumed that the hole dip and azimuth remained constant. |
| 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. _ |
Drill spacing is not considered appropriate for the Mineral Resource and Ore Reserve estimation procedure(s). Regional drilling in the Mauretania project area is considered very broad and infill drilling has been designed to increase our knowledge and number of datapoints. |

| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
Limited exploration has been conducted over the Mauretania Project Area. Minor regional mapping and rock chipping has been undertaken by previous explorers. The majority of this work was completed in the 1970’s by Australian Development Pty Ltd and in the 1980’s by Normandy Tennant Creek. Adelaide Petroleum NL (Sabminco NL JV) drilled 11 RC holes at the Black Cat Prospect (1988) however did not discover significant results and no further work was done. Matana Minerals NL also mapped the general area in 1989. Several gold nuggets have been located within the area by local prospectors. No exploration after 1999 has been completed until Emmerson who commenced work. |
| Geology | Deposit type, geological setting and style of mineralisation. |
Mineralisation within the area consists of hematite- quartz-jasper ironstone within sediments of the Warramunga Formation. Target style for Emmerson is non magnetic ironstone related iron oxide copper gold where hematite shale plays an important role in mineralisation. Anomalies (targets) lie within a defined structural corridors and may (but not always) be associated with ironstone. Very limited drilling has targeted the non magnetic ironstones within this area. Mineralisation is considered to be Proterozoic Iron Oxide Copper Gold (IOCG) mineralisation of similar style and nature to other mineralisation / deposits in the Tennant Creek Mineral Field |

Mineralised intersections are reported as down hole composite drill intervals and not weighted averages. These results are exploration results only and no allowance is made for recovery losses that may occur should mining eventually result, nor metallurgical flow sheet considerations. It must be noted that RAB drilling by nature can contaminate samples during the drilling process and although considered significant in a regional sense it must be understood that confirmation RC drilling is required to qualify the initial RAB intersections. No cut-off grades have been used has been used for reporting of exploration drill results. |
| 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 drillhole angle is known, its nature should be reported. If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (eg ‘downhole length, true width _not known’). _ |

Geological mapping including rock chip sampling was undertaken prior to the RAB drilling commencing. Rock chip results must be viewed with caution as supergene enrichment (nugget effect) is likely to be present. Rock chip assay results are not indicative of deeper mineralisation in the area.
