Legend Mining Limited (Legend) is pleased to provide assay results from diamond drillholes RKDD017, 016 and 014 and an update on drillholes RKDD018-020 at the Mawson prospect within the Rockford Project, Fraser Range, Western Australia (see Figure 7). The results are discussed in detail in the body of this announcement.
Legend Managing Director Mr Mark Wilson said: “The paydirt grades returned over 35.95m in hole 17 confirm this to be the best hole drilled at Mawson to date. The mineralisation remains open to the northeast, southwest and east of the current diamond drilling and requires further analysis of all datasets prior to planning step out RC/diamond holes.”

Diamond Drillhole Assays Received
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 12m interval of massive sulphide intersected in RKDD013 at 239.2m (see Figures 1 & 2). The hole intersected three significant massive sulphide (pyrrhotite-chalcopyrite-pentlandite) intervals at 158.6m, 193.1m and 227.8m downhole, with the upper two intervals hosted by mafic/ultramafic intrusives and the lower interval hosted in metasediments. The lower 19.8m interval of massive sulphide in RKDD017 correlates with the lower interval in RKDD013 and occurs approximately 25m up dip to the west of the RKDD013 intersection (see Figure 2). Full assay results for RKDD017 have been received and are shown in Table 3.
DHTEM in RKDD017 has identified a 50,000-60,000S conductor associated with the lower 19.8m sulphide interval with a NE-SW orientation. The DHTEM also identified a 60,000-65,000S offhole conductor located southwest of the upper massive sulphide mineralisation at ~158m. These results suggest the mineralisation continues south of the RKDD013-017 section (Figure 2) and to the west of RKDD016.

RKDD016 (Assay Results)
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 1.85m interval of semi-massive to heavy disseminated sulphide at 112.7m returning an intersection of 1.85m @ 1.13% Ni, 0.35% Cu, 0.05% Co.
DHTEM in RKDD016 identified a strong 45,000-50,000S offhole conductor at 165-175m which correlates with the upper massive sulphide in RKDD017 to the northwest. The DHTEM also defined a 50,000-60,000S conductor associated with the lower sulphide interval in RKDD017. These results suggest RKDD016 has been drilled to the east of the main mineralised trend as defined by RKDD013 and RKDD017 to the north.

RKDD014 (Assay Results)
RKDD014 was 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). The hole intersected a 7.7m interval containing semi-massive to massive, blebby and disseminated sulphides (pyrrhotite-chalcopyrite-pentlandite) hosted within metasediments at 249.9m downhole (see Figure 3 & Table 4). This intersection is interpreted to be the eastern down dip extension (~35m) of the sulphides intersected in RKDD011 from 217.5m downhole.

Recently Completed Diamond Drillholes
RKDD018
RKDD018 was designed to test the eastern extension of sulphide mineralisation in both the upper disseminated and lower massive sulphide intervals intersected in RKDD008 (see Figure 1). The hole intersected a 12.85m upper mafic/ultramafic intrusive containing gossan, massive, brecciated and disseminated sulphides all displaying a strong supergene overprint from 103.7m (see Figures 4 & 5). Below this intrusive is a thin metasediment, followed by ~101m of olivine bearing mafic intrusive with varying amounts of disseminated and blebby sulphide, before ending in a thick footwall metasediment. All assays for RKDD018 are pending.

RKDD019 & RKDD020 – NE Mawson
Diamond drillholes RKDD019 and RKDD020 were completed at NE Mawson testing FLTEM conductors D13 and D15 respectively (see Figure 6). Both conductors have moderate to strong conductances and are of relatively limited size, unlike most other Mawson conductors which are considerably larger and stratigraphic in character (see Table 5).

RKDD019 intersected a mixed sequence of alternating mafic intrusive and metasediment with the hole ending a thick metasedimentary package containing several graphitic units. These graphitic units adequately explained the D13 conductor and confirmed with DHTEM surveying. No significant mineralisation was intersected in the drillhole with only minor disseminated sulphide observed in the mafic intrusives.
RKDD020 intersected an upper metasedimentary unit dominated by BIF followed by a mixed mafic/ultramafic intrusive, before ending in a lower metasedimentary unit containing several graphitic units. These graphitic units adequately explained the D15 conductor and confirmed with DHTEM surveying. No significant mineralisation was intersected in the drillhole.

Appendix 2: Legend Mining Ltd – Diamond Drilling Programme 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 RKDD014-020 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 |
•Drill core sample recoveries for the HQ and NQ2 core were measured |

| 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. |

| 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; |
•Detailed high quality aeromagnetic/ gravity datasets, aircore drilling ground EM surveys and DHTEM surveys used to target drilling. •GEM Geophysics completed downhole EM surveying of in drillholes RKDD016-020. |
