Comprehensive Regional Programmes Advance Rockford Project
-
Diamond drill holes at Crean, Hurley, and the new Northerly prospect intersect prospective host rocks
-
MLTEM survey at Northerly identifies a large shallow conductor
-
Aircore drilling continues to identify a future pipeline of prospects
Legend Mining Limited (Legend) is pleased to announce initial results of diamond drilling at the Crean, Hurley, and Northerly prospects, an MLTEM survey at Northerly and regional aircore across the Rockford Project, Fraser Range, Western Australia (see Figure 1).
Details of the five diamond holes CRDD001, CRDD002, HYDD001, HYDD002, and NODD001, the Northerly MLTEM survey, and the 213 hole for 12,168m aircore drilling programme are contained in the body of this report.
Legend Managing Director Mr Mark Wilson said: “Our field team have done an exceptional job to execute these programmes with the industry wide labour difficulties being experienced under the current border travel restrictions.
“The early success from the new Northerly prospect is particularly pleasing with anomalous geochemistry indications from aircore, sulphides in intrusive host rocks observed in diamond drill core and a large shallow conductor from the MLTEM survey.
“The significance of all of these programmes will be better understood once all assays and analysis of the results are collated.”

TECHNICAL DISCUSSION
Regional exploration comprising diamond drilling, Moving Loop Electro Magnetic (“MLTEM”) surveying and further aircore drilling has been completed at the Rockford Project over tenements E28/1718, E28/1727, and E28/2404 (see Figure 1 and Figure 5). These tenements contain the Crean, Northerly, and Hurley prospects, which have been identified as favourable Ni-Cu-Co targets by Legend through systematic exploration utilising aircore drilling and innovative MLTEM surveys. The Crean and Hurley prospects lie within the same NE-SW trending structural corridor which hosts the Silver Knight and NovaBollinger Ni-Cu deposits to the south.
Diamond drilling completed has confirmed that Crean, Hurley, and Northerly are prospective orthomagmatic Ni-Cu intrusive hosts, akin to the known deposit hosts of Nova-Bollinger and Silver Knight in the Albany-Fraser Belt. Future work programmes at Crean, Hurley, and Northerly will include assessment of geological, geochemical, geophysical, and structural results from completed diamond drilling, followed by planning of extensive aircore drilling, innovative MLTEM/FLTEM, and targeted diamond drilling. These work programmes will be designed to define the target intrusion geometry at each prospect, as well as to identify and target mineralisation through systematic exploration, with the aim to discover multiple economic Ni-Cu sulphide accumulations.
Crean Prospect – E28/1718
Diamond Drillhole CRDD001
Legend’s first diamond drillhole into the Crean Prospect, CRDD001, was drilled targeting the C1 FLTEM plate (see Figure 1, Figure 2, and Appendix 1). The drillhole intersected an interpreted recrystallised gabbronorite intrusive between 58.6m and 78.3m downhole before entering a dominantly metasedimentary package of psammite and granite gneisses to 203.9m. Recrystallised gabbronorite with lesser peridotite was intersected to 254.5m before an olivine-rich peridotite was intersected through to 297.2m. Recrystallised gabbronorite with interleaved carbonate veining was intersected through to 340.95m, followed by interleaved recrystallised gabbronorite and metasedimentary assemblages of graphitic pelite, psammite and mafic granulite, with minor pegmatitic veining to 568.4m end of hole. Minor pyrrhotite and chalcopyrite sulphide was noted associated with interleaved recrystallised gabbronorite and metasedimentary assemblages. The C1 FLTEM conductor is interpreted to have been intersected between 447.1m and 472.7m, where significant zones of banded graphite and pyrite were intersected in a dominantly graphitic pelitic gneiss. Selected samples have been sent for assay and further assessment is required following receipt of geochemical results from the laboratory.
DHTEM has been completed on CRDD001 with results confirming the FLTEM conductor has been explained (see Table 1).
Encouragingly, prospective mafic and ultramafic lithologies have been encountered in CRDD001. This validates the aircore assessment methodology to delineate Ni-Cu-Co prospective intrusive suites. Significant thicknesses of mafic-ultramafic intrusives intersected suggest Crean is a large intrusive body. Additional aircore is currently being planned to define the footprint of the Crean intrusion.
Diamond Drillhole CRDD002
CRDD002 was drilled targeting a cluster of anomalous aircore geochemistry results (see Figure 1, Figure 2, and Appendix 1). Highly prospective mafic and ultramafic assemblages were identified below 26m of transported cover. Olivine gabbronorites, gabbronorites, and peridotite were encountered to 95.5m downhole before a zone of interleaved recrystallised gabbronorite and norite/mafic granulite with clear

evidence of country rock contamination to 138.5m. The drillhole then intersected a gabbronorite and peridotite assemblage to 167.8m before a package of psammitic and granitic gneisses to 278.75m. A thick second intrusive package was encountered through to 311.9m, comprising dominantly gabbronorite with minor granitic gneiss, before finishing in a psammitic gneiss at 324.4m bottom of hole. Minor disseminated pyrrhotite and chalcopyrite was identified associated with the lower intrusive package. Selected samples have been sent for assay and further assessment is required following receipt of geochemical results from the laboratory.
DHTEM has been completed on CRDD002 with no conductors identified.
Akin to CRDD001, CRDD002 validates the use of systematic aircore to define prospective intrusions. Additional aircore will focus on defining the Crean intrusion footprint as the next step.

Hurley Prospect – E28/2404
Diamond Drillhole HYDD001
Legend’s first diamond drillhole into the Hurley Prospect, HYDD001, was drilled targeting the H1 MLTEM plate (see Figure 1, Figure 3, and Appendix 1). Transported cover was intersected to 85m downhole before transitioning into a thick zone of norite, leuconorite, and gabbronorite to 232m. The drillhole then intersected a metasedimentary assemblage of pelites and graphitic pelites with intervals of massive graphite between 274m and 294m, which explains the MLTEM conductor target (see Table 1). Below the graphitic unit, the drillhole entered a package of gabbronorite and narrow zones of pyroxenite interleaved with metasedimentary units to 428m before finishing in a pelitic gneiss at 531.4m bottom of hole. Both the interpreted upper mafic intrusive package and lower mafic/ultramafic intrusive package contained variable amounts of disseminated and blebby pyrrhotite and chalcopyrite with fine graphite and magnetite also noted, suggesting contaminated intrusions. The intrusions are interpreted to be prospective hosts for Ni-Cu mineralisation. Selected samples have been sent for assay and further assessment is required following receipt of geochemical results from the laboratory.
DHTEM has been completed on HYDD001 with results confirming the H1 MLTEM conductor has been explained (see Table 1).
Diamond Drillhole HYDD002
HYDD002 was drilled targeting the H3 MLTEM plate (see Figure 1, Figure 3, and Appendix 1). Transported cover was intersected to 74.3m downhole before intersecting an amphibolised mafic assemblage with narrow zones of altered ultramafic to 152m. The drillhole then intersected a thin metasedimentary package of pelites, before intersecting a dominantly leuconorite intrusion with minor pelitic gneiss to 260m and a zone of semi-massive graphitic pelite at 163m. From 260m the drillhole intersected a gabbronorite and a pyroxenite intrusive assemblage, with lesser norite and leuconorite to 365m. Below this, the drillhole intersected a dominantly metasedimentary package of pelites with minor narrow zones of leuconorite intrusion to bottom of hole at 445m. Both the interpreted upper mafic intrusive package and lower mafic/ultramafic intrusive package contained variable amounts of disseminated and blebby pyrrhotite and chalcopyrite with fine graphite and magnetite also noted, suggesting contaminated intrusions (see Photo 1). The intrusions are interpreted to be prospective hosts for Ni-Cu mineralisation. Selected samples have been sent for assay and further assessment is required following receipt of geochemical results from the laboratory.
DHTEM has been completed on HYDD002 with results confirming the H3 MLTEM conductor has been explained (see Table 1).

Northerly Prospect – E28/1727
Diamond Drillhole NODD001
The Northerly prospect was identified though aircore drilling by the Creasy Group, with its prospectivity confirmed by recently completed aircore drilling by Legend (see Figure 1 and Figure 4). Diamond drillhole NODD001 represents the first diamond drillhole into the Northerly Prospect, specifically targeting anomalous aircore geochemistry with supporting petrological verification of prospective Ni-Cu-Co mineralisation host rocks. NODD001 was drilled HQ3 triple tube from surface to preserve the regolith profile with a view to understanding the regolith zone producing the anomalous aircore geochemical response. Transported cover sequences were encountered to 33.4m downhole before intersecting insitu weathered ultramafic saprolitic clays to 42.4m. Weathered ultramafic with abundant carbonate veins and minor goethite was intersected to 70.0m before encountering a zone of weathered olivine gabbronorite, norite, biotite norite, and peridotite, with minor pegmatite to 100.76m. Fresh magmatic sulphide blebs of pyrrhotite, pentlandite, and chalcopyrite were observed between 92.93m and 100.76m, confirming the fertility of the encountered mafic/ultramafic intrusive (see Photo 2). Granitic and semipelite gneisses were intersected from 100.76m to 217.9m before the drillhole intersected dominantly recrystallised norite and gabbronorite to bottom of hole at 347.7m. Selected samples have been sent for assay and further assessment is required following receipt of geochemical results from the laboratory.
DHTEM on NODD001 is pending at the time of writing.

ASX Announcement
The visual results from the first diamond drillhole into the Northerly prospect are highly encouraging. The presence of primary Ni-Cu sulphides in fertile host lithologies below anomalous aircore suggest the discovery of a new fertile intrusion at the Rockford project, akin to known fertile intrusions within the belt including Nova, Silver Knight, Mawson, Octagonal, and Magnus.
MLTEM Survey
A MLTEM survey has been completed across the greater Northerly prospect identifying a large, shallow conductive feature west of NODD001 (see Figure 4 and Table 1). Interestingly the NNW orientation of the conductor is offset to the regional NNE geological strike, suggesting this is not a stratigraphic feature. The conductor also lies on the western margin of a gravity high. Additional MLTEM and FLTEM is planned to close off or extend the current feature before initial aircore drill testing.

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. •Aircore drilling was undertaken on a nominal 400/200m spacings testing aeromagnetic and gravity targets. Infill drilling at 50/100m spacings was completed around anomalous drillholes. •The residual (non-transported) portion only of each drillhole was originally sampled as 4m composites to the end of hole, with a 1m bottom of hole sample also collected.

| 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. |
•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. |
•All assay results are pending. |
| 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 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. |
•No assay results have been received, however photographs of the sulphide interval is provided in the body of this report. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological _observations; geophysical _ |
•Detailed high quality aeromagnetic and gravity datasets, aircore drilling, ground EM surveys and DHTEM surveys have been used to target drilling. |
