Legend Managing Director Mr Mark Wilson said: “The assays reported in this announcement are broadly in line with our expectations from visual observations of the core at site. The key point is the distance between massive sulphide occurrences and the broader mineralised intercepts give us the geological confidence of a fertile mineralised system of significant scale.
“Both the drilling and downhole EM results have continued the evolvement of our geological understanding of the Mawson intrusion. This is the objective of the current stage of our systematic ongoing exploration strategy at this prospect.”

TECHNICAL DISCUSSION
Below is a technical summary of the assay results and DHTEM results received at the Mawson Ni-Cu-Co prospect since the ASX Announcement 1 June 2021 .
Assay results received from RKDD043/044/046 (see Figure 1) are in line with visual estimations. Multi-element data received as part of the assay suite will continue to provide critical data to existing datasets to further evolve the understanding of the chonolith driving the mineralisation at Mawson. This step-out drilling continues across Mawson at the time of writing, and the Company will update the market as results come to hand.

Assay Results
Assay results have been received for diamond drillholes RKDD043/044/046 ( see ASX Announcements 28 May 2021 and 1 June 2021 ).
Diamond drillhole RKDD043 targeted the interpreted south-west extension of the eastern chonolith (see Figure 1, Figure 2, and Table 1). RKDD043 intersected a metasedimentary package from 52.3m to 79.7m before intersecting a variably mineralised gabbronorite with interleaved metasediments, anorthosite, and pegmatitic zones from 79.7m to 263.3m downhole. Mineralisation intersected included disseminated, blebby, heavy disseminated, brecciated, nettextured, semi-massive, and massive magmatic Ni-Cu sulphide. Semi-massive and net-textured sulphide was intercepted at 131.6m to 132.8m, 170.1m to 176.95m, and 178.5m to 180.85m with semi-massive and massive sulphide intercepted at 180.85m to 183.3m downhole. Textures of the sulphides across these zones indicate remobilisation of sulphide, suggesting the drillhole has not intersected the primary sulphide source, and assay results received confirm this observation (see Photo 2).

RKDD044 was drilled off the north-eastern end of the EAGA, targeting the north-eastern interpreted extension of the eastern chonolith (see Figure 1, Figure 3, and Table 1). The drillhole intersected a weakly mineralised gabbronorite from 92m to 381m downhole before intersecting a meta-BIF and orthogneiss assemblage to 403.2m. The drillhole then entered an interpreted marginal early-stage recrystallised gabbronorite to 437.9m before intersecting a heavily mineralised gabbronorite to 476.75m. A zone of net-textured, semi-massive, and massive Ni-Cu sulphide was intersected from 453.2m to 458.1m. Detailed structural logging of RKDD044 suggests the zone of semi-massive and massive mineralisation is focused along pegmatoidal leuconorite veins with identifiable clasts of olivine gabbronorite, confirming the remobilised nature of the sulphide encountered (see Photo 3). Results are in line with visual estimations and in conjunction with structural observations, suggest the mineralisation encountered in RKDD044 is not the primary source.

Diamond drillhole RKDD046 returned assay results in line with visual assessment of mineralised intervals (see Figure 1, Figure 3, and Table 1). The disseminated zones intersected in mineralised intrusion between 300m and 344m suggest a fertile Ni-Cu system, resulting in upgrading of mineralisation when sulphide zones focus in a structural trap. The mineralised intrusion remains open to the west, east and north. Further expansion drilling is planned to follow the mineralised intrusion in the open directions.

DHTEM
DHTEM remains ongoing on completed diamond drillholes across Mawson. The latest DHTEM conductors are presented in Table 2.
DHTEM results from RKDD053 confirm the complex nature of the sulphide zone intersected in the drilling. DHTEM results suggest a limited size zone of sulphide lenses striking north-south. Coupled with geological and structural observations, this sulphide zone is mobile and is not the primary source/accumulation.
DHTEM results from RKDD044 support geological and structural observations that the sulphide zone is limited in size. The conductor orientations however support the structural vector, suggesting a prospective target area to the north/north-west of RKDD044.
DHTEM surveying and/or modelling is pending for RKDD045/046/048/049/051/052 at the time of writing. Large offhole features have been identified in data from RKDD045/047/048/052, with more modelling required to constrain features. These offhole features are proximal to the MLTEM D1 conductor, complicating interpretation due to the masking effects of D1.

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 NQ 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). |

| Geology | • Deposit type, geological setting and style of mineralisation. |
•The primary target is Nova style nickel-copper mineralisation hosted in mafic/ultramafic intrusives within the Fraser Zone of the larger Albany- Fraser Orogen. •Secondary targets include VMS style zinc-copper-lead-silver mineralisation and structurally controlled Tropicana style gold. |
| 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. |
•Drillhole details are provided in Appendix 1. |
| 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 low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
•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. |
•Detailed high quality aeromagnetic and gravity datasets, aircore drilling ground EM surveys and DHTEM surveys have been used to target drilling. •GEM Geophysics completed downhole EM surveying of RKDD050 and 053. DHTEM Details ➢Loop Size: 300mx300m, double turn ➢Station Spacing: 2-10m intervals ➢Sensor: B-field DigiAtlantis ➢Base/frequency: 0.125Hz ➢Stacking: ~32-64 stacks, 2-3 repeatable readings |
| Further work | • The nature and scale of planned further work (e.g., 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. |
•Submit selection of completed diamond drillholes for geochemical analysis. •Assessment of geochemical results. •Complete DHTEM surveying of all drillholes. •Full integration of geological, geophysical and geochemical data. •Plan further diamond and RC drillholes. |
