TECHNICAL DISCUSSION
An additional four diamond drillholes (RKDD014-017) totalling 1,275.5m have been completed at Mawson and assay results received from RKDD013 (see Figure 1 and Table 1). Downhole electromagnetic (DHTEM) surveying has been completed in holes RKDD014-015, with surveying of holes RKDD016-017 planned over the next five days. The drillholes were testing a combination of geophysical DHTEM targets and extensions to mineralisation intersected in previous drilling.
A summary of the mineralisation intersected in the recent drilling and assays received is as follow:
-
RKDD017 intersected three significant intervals of massive sulphide (158.6-166.05m, 193.1-195.9m and 227.8-247.6m) totalling 30.05m.
-
RKDD013 returned assays of: 12.0m @ 2.36% Ni, 1.36% Cu, 0.12% Co from 239.2m and 1.5m @ 2.33% Ni, 3.76% Cu, 0.12% Co from 257.5m.
-
RKDD014 intersected 5.5m of semi-massive and massive sulphide from 249.7m downhole.
-
RKDD015 intersected a broad 61.9m disseminated sulphide interval from 97.9m downhole.
-
RKDD016 intersected a 3.7m interval of semi-massive to heavy disseminated sulphide from 112.7m downhole, plus five 5-10m intervals with minor (1-3%) disseminated sulphides.
-
See Appendix 3 for further descriptions of sulphide mode, type and percentage.

RKDD017
RKDD017 was designed to test a strong 50,000-60,000S offhole conductor identified in drillholes RKDD010 and RKDD013, along with extensions to the 12.0m interval of massive sulphide intersected in RKDD013 at 239.2m. The hole intersected three significant massive nickel-copper sulphide intervals: 7.45m from 158.6m, 2.8m from 193.1m and 19.8m from 227.8m. The upper two intervals are hosted by mafic/ultramafic intrusives, while the lower interval is hosted in metasediments (see Figures 1 & 2). Four other minor occurrences of massive and semi-massive sulphides (0.6-2.0m downhole thickness) were also intersected in the drillhole totalling 4.65m.
The main lower 19.8m interval of massive sulphide in RKDD017 coincides with the lower interval in RKDD013 and occurs approximately 25m up dip to the west of the RKDD013 intersection (see Figure 2). Core photos of the lower (19.8m) and upper (7.45m) massive sulphide intervals are provided in Appendices 1 and 2 respectively.
DHTEM in RKDD017 is planned over the next five days, while drill core sampling will be completed following the completion of structural logging.

RKDD013
RKDD013 was designed to test a strong 50,000-60,000S DHTEM conductor identified in RKDD010 and also test for extensions to the sulphide mineralisation intersected in drillhole RKDD008 (see Figures 1 & 2). The drillhole intersected a 12m interval of massive nickel-copper sulphide mineralisation from 239.2m and a further 1.5m from 257.5m downhole hosted in mafic intrusive. Assay results from these two intervals have been received and summarised in Table 2.

RKDD014
RKDD014 was originally designed to test the eastern extension of massive sulphide mineralisation intersected in RKDD011, and targeted a strong 50,000-60,000S offhole DHTEM plate identified in RKDD011 (see Figure 1).
RKDD014 intersected a downhole sequence of: an upper metasediment, 62m of gabbronorite, followed by a thick lower metasediment to the end of hole. The lower metasediment contained a 5.5m interval of semi-massive and massive sulphide at 249.7m downhole, along with three other minor (0.25m-0.65m) occurrences of massive sulphide (see Figure 3). The 5.5m sulphide interval is interpreted to be the eastern down dip extension (~35m) of the sulphides intersected in RKDD011 from 217.5m downhole.
The DHTEM modelling from RKDD014 clearly defined the upper and lower sulphides zones (50,000-100,000S) in RKDD011 to the west as shown in Figure 3 below. The mineralisation in RKDD014 is interpreted to continue to the east, however its extent is unknown due to the western sulphide intervals dominating the downhole response. Drill core samples from RKDD014 have been submitted for assay with results expected in 3 weeks.

RKDD015
Diamond drillhole RKDD015 was designed to test the northern extension of massive sulphide mineralisation in RKDD011 and the eastern extension of the upper sulphide zone in RKDD007 (see Figure 1).
RKDD015 intersected a downhole sequence of: an upper unit of sulphide bearing mafic/ultramafic intrusives, a thick metasedimentary unit, a lower sulphide bearing mafic/ultramafic, metasediment, before ending in mafic intrusive (see Figure 4). The upper mafic/ultramafic intrusive contains 61.9m of disseminated, heavy disseminated, blebby, net-textured and minor semi-massive sulphides (pyrrhotite-chalcopyrite-pentlandite) from 97.9m downhole. This interval correlates directly with the upper sulphide interval in RKDD007 to the west and RKDD012 to the north. The lower mafic/ultramafic intrusive contains 24.2m of 3-5% disseminated sulphides.
==> picture [480 x 349] intentionally omitted <==

RKDD016
Diamond drillhole RKDD016 was designed to test the southern extension of massive sulphide mineralisation in RKDD013 (see Figure 1). The hole intersected a thick sequence of ultramafic and mafic intrusives to 283m downhole, before ending in mafic granulite. The ultramafic/mafic unit contained a 3.7m interval of semi-massive to heavy disseminated sulphide at 112.7m, along with five 5-10m intervals with minor (1-3%) disseminated sulphides.
DHTEM in RKDD016 is planned over the next five days, while drill core samples have been submitted for assay with results expected in 3 weeks.

Appendix 4: Legend Mining Ltd – Diamond Drilling Programmes Mawson Prospect JORC Code Edition 2012: Table 1
Section 1: Sampling Techniques and Data
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| Sampling techniques | • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. • 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 (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
Diamond drilling was used to produce half NQ2 core samples (between 0.2m-1.2m) which were submitted to Intertek Genalysis Laboratory Services Perth for geochemical analysis. Sample intervals were based on geology and style of sulphide occurrence. QAQC standard samples were included. Samples were analysed for: Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Ho, In, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Pr, Rb, Re, S, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn, Zr by methods 4A/MS48R and 4AH/OE (four acid digest with ICP-MS finish). Au, Pt, Pd by method FA50/MS (fire assay with an ICP-MS finish). Specific Gravity measurements were taken by the laboratory for all half core samples with massive sulphides. |
| Drilling techniques | • Drill type (e.g. 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.). |
Diamond drillholes RKDD014-017 were pre-collared using the mud rotary technique. No samples were recovered from the mud rotary pre- collar. The remainder of the hole was diamond drilled with HQ into solid/fresh rock, followed by NQ2 coring to end of the hole. Orlando Drilling completed the drilling. |
| Drill sample recovery | • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure |
Drill core sample recoveries for the HQ and NQ2 core were measured and recorded in drill log sheets. Drill core orientation was recorded when possible at the end of each drill run (line on bottom of core). No relationship has been determined betweensamplerecoveries and |

grade and there is insufficient data to determine if there is a sample bias. |
|
| 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. |
Geological logging of drillholes included; lithology, grainsize, texture, deformation, mineralisation, alteration, veining, colour, weathering. Drill core logging is qualitative and based on drill core retained in core trays. The drillhole was logged in its entirety. |
| 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. |
Selected sawn half NQ2 core samples based on geology and sulphide occurrence were submitted for geochemical analysis. The size of the sample from the diamond drilling method is considered appropriate for the mineralisation style sought and for the analytical technique used. Sample preparation includes; drying, crushing and pulverising before analysis. A quartz wash will be utilised between high grade samples to avoid any carry over. QAQC standard samples were included. |
| 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. |
Core samples were analysed for: Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Ho, In, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Pr, Rb, Re, S, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn, Zr by methods 4A/MS48R and 4AH/OE (four acid digest with ICP-MS finish).

| • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
QAQC standard samples were included. In addition, reliance is placed on laboratory procedures and internal laboratory batch standards and blanks. All samples were analysed by Intertek Genalysis Laboratory Services Perth. |
|
| 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. |
Significant intersections were verified by senior exploration personnel. Primary data was collected in the field using a set of standard logging templates and entered into a laptop computer. The data was forwarded to Legend’s database manager for validation and loading into the company’s drilling database. No adjustments of assay results have been undertaken. |
| 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 drillhole collars were surveyed with a handheld GPS unit with an accuracy of ±5m which is considered sufficiently accurate for the purpose of the drillhole. All co-ordinates are expressed in GDA94 datum, Zone 51. Regional topographic control has an accuracy of ±2m based on detailed DTM data. |
| 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. |
Diamond drillhole spacing is not regular or grid based, with the location of individual drillholes governed by targeting the position of modelled EM conductor plates and anomalous geochemical results in previous drillholes. Only selected sawn NQ2 half core samples based on geology and sulphide mineralisation were submitted for geochemical analysis. Diamond drillholes RKDD014-017 were targeting extensions to mineralisation in adjacent holes with support from modelled offhole DHTEM plates. |
| 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. |
Diamond drillholes RKDD014-017 were planned to intersect the interpreted mineralisation extensions and modelled DHTEM plate perpendicular to strike. The relationship between drill orientation and mineralisation is unknown. |

| sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |

| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. 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. |
Individual sample assays and weighted averages are presented. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
The drill core has been oriented to enable structural logging and evaluation of true thicknesses of the mineralised intervals. Drillhole intercepts/intervals are measured downhole in metres. |
| 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. |
Project and drillhole location maps and drill sections have been included in the body of the report. |
| Balanced reporting | • Where comprehensive reporting of all Exploration Results is not practicable, _representative reporting of both _ |
Assay results presented are balanced. |

| 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. |
