Diamond drilling of DHTEM targets ongoing
Legend Mining Limited (Legend) is pleased to announce assays received from both diamond and RC drillholes at the Mawson prospect within the Rockford Project, Fraser Range, Western Australia (see Figure 3). Details are in the body of this announcement along with an update on current diamond drilling progress.
Legend Managing Director Mr Mark Wilson said: “The assays from diamond hole 023 are in line with our expectations from visual observations and structural interpretations of the core. The key objective of the ongoing work at Mawson is to look for and find the primary source of this mineralisation.
“The anomalous RC assays returned from the three holes in the Eastern Geochemical Anomaly have added to the geochemical and geology datasets for this area. Ultimately, the assimilation of all these datasets will lead to diamond drill targets over this eastern area of Mawson.
“As per the detail in the body of this announcement, the current drilling of the two offhole conductors, announced to the ASX on 21 October 2020, is a work in progress.”

TECHNICAL DISCUSSION
RKDD023 Assay Results
Assay results have been received from diamond drillhole RKDD023 at Mawson (see Figure 1, Table 1, and Appendix 1). Diamond drillhole RKDD023 was designed to test a very strong 25,00030,000S offhole conductor identified from diamond drillhole RKDD021. As reported to the ASX on 8 September 2020, RKDD023 intersected a wide zone of Ni-Cu mineralisation over 90m downhole from 216.45m to 310.4m in an interleaved intrusive and metasedimentary assemblage, before finishing in metasedimentary package. The host intrusive is a mixture of olivine gabbronorite and gabbronorite, with massive, semi-massive, net textured, matrix, heavy disseminated, disseminated, and blebby Ni-Cu sulphides throughout. The massive Ni-Cu sulphide accumulations from 221.9223.75m, 228.7-236.9m, and 237.8-240.7m downhole occur within the interleaved metasedimentary units, with distinctive brecciated margins, indicating sulphide mobilisation. This textural observation, combined with the evidence of limited sulphide extension veining, suggests the mineralised zone intersected is remobilised and proximal to the source. Assay results received for RKDD023 confirm the field observations of remobilised sulphide, suggesting the mineralisation intersected is not the primary source.

RKRC023-RKRC027 Assay Results
Assay results have been received from drillholes RKRC023 through RKRC027 over the eastern geochemical anomaly. Three of the five holes returned anomalous Ni-Cu-Co intercepts (see Table 2 & Figure 2). Results confirm drilling visual observations that primary Ni-Cu mineralisation continues below the aircore drilling into the primary intrusive rock suite. Geological, geochemical, and geophysical datasets continue to be integrated on receival of data to design and target potential Ni-Cu sulphide accumulations with diamond drilling.

Diamond Drilling Update
Diamond drilling of the offhole DHTEM conductors from RKDD025 and RKDD026 as announced to the ASX on 21 October 2020 has been disrupted by unforeseen weather and associated logistical issues.
The first proposed hole was to test the 6,000-15,000S conductor (see Figure 1). The hole did not intersect the conductor at the modelled depth. Subsequent DHTEM in the hole has suggested the feature is below the bottom of the hole and geophysical advice is the hole be extended. This is scheduled once the current hole (testing the 25,000-70,000S conductor off hole from RKDD025 – see Figure 1) is completed.
Mawson Future Programmes
-
Diamond drill testing of DHTEM targets generated from RKDD023, RKDD025, and RKDD026.
-
Ongoing DD drilling programme targeting known sulphide mineralisation, geochemical anomalies, DHTEM targets, and structural targets.
-
Ongoing integration of DD, RC, aircore and geophysical datasets to evolve 3D emplacement model of Mawson and assist future diamond drillhole planning/design.

| 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. |
DD Drilling Diamond drilling was used to produce half HQ and 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). RC Drilling RC drilling was undertaken along E-W traverses with holes nominally spaced 100-150m apart testing geochemical, geological, and gravity targets. Each metre drilled was collected in a green plastic bag (20-30kg) with a 1m representative sample (2-3kg) also collected via a rig mounted cone splitter. The transported cover in each hole was not sampled. The residual and fresh portion of each drillhole was sampled as 4m composites to the end of hole. Where significant sulphides were observed, 1m samples were taken All samples weighed 2-3kg. QAQC standards and duplicate samples were included routinely (approximately 1 each every 50 samples). Au was analysed by fire assay with an ICP-OES finish. A four acid digest with ICP-MS finish was used for a multi-element suite including: Ag, Al, As,Ba,Be,Bi, Ca, Cd, Ce, Co, Cr, |

| 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. |
DD Drilling 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 HQ and NQ2 half core samples based on geology and sulphide mineralisation were submitted for geochemical analysis. Diamond drillhole RKDD023 was targeting an offhole DHTEM plate generated from RKRC021. RC Drilling RC drilling was at a nominal 100- 150m spacing along E-W traverses. Drillholes are sampled in the residual and fresh portions of the profile only as 4m composites, with detailed 1m sampling of sulphide bearing |

• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
The Rockford Project comprises nine granted exploration licences, covering 2,430km2, (Legend manager). Rockford JV tenements: E28/2188, 2189, 2192 (70% Legend, 30% Rockford Minerals Pty Ltd) E28/1716, 1717, 1718, 1727 (70% Legend, 30% Ponton Minerals Pty Ltd). Legend 100%: E28/2404, 2405. The Project is located 280km east of Kalgoorlie mostly on vacant crown land with the eastern portion on Kanandah Pastoral Station. There are no Native Title Claims over tenements E28/1716, 1717, 2192, 2405. Tenements E28/2188, and E28/2189 are covered 20% and 85% respectively by the Untiri Pulka Native Title Claim. Tenements E28/1718, E28/1727 & E28/2404 are covered 90%, 20% and 100% respectively by the Ngadju Native Title Claim. The tenements are in good standing and there arenoknown impediments. |

| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by otherparties. |
Not applicable, not referred to. |
| 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. |
Refer to table of drillhole collars in Appendix 3. |
| 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. |
Individual sample assays and weighted averages are presented. |
