ASX:LEG
8 September 2020 ASX Announcement
-
12.95m of Massive Nickel-Copper sulphides in diamond hole RKDD023 within a +90m intercept of sulphide mineralisation at Mawson
-
RKDD023 intersects a +90m mineralised zone of Ni-Cu sulphide including:
-
12.95m massive sulphide
-
7.55m semi-massive sulphide
-
multiple zones of net-textured, matrix, and heavy disseminated sulphide
Legend Mining Limited (Legend) is pleased to provide an update from diamond drillhole RKDD023, which was designed to test the 25,000-30,000S conductor at the Mawson Prospect within the Rockford Project, Fraser Range, Western Australia (see ASX announcement 27 August 2020). The details are discussed in the body of this report, along with an update of the ongoing RC drilling programme.

Legend Managing Director Mr Mark Wilson said: “The discovery of another 12.95m of massive nickelcopper sulphide in diamond drillhole 23, circa 200m from the previously announced massive sulphides, is a quantum boost for the potential of the Mawson Prospect. The nature of the mineralisation suggests we are closer to the intrusive source but we are not there yet. Downhole EM from this hole, which is now underway, is designed to provide data to assist in planning future diamond holes in this immediate vicinity.
“Importantly, the RC drilling confirms the Mawson intrusive complex extends north and east of the known Mawson nickel-copper sulphide mineralisation, confirming the prospectivity for mineralised intrusives below the eastern aircore geochemical anomaly. The RC holes are also a great platform for downhole EM.”

TECHNICAL DISCUSSION
RKDD023 Summary
Diamond drillhole RKDD023 was designed to test a very strong 25,000-30,000S offhole conductor identified from diamond drillhole RKDD021 (see Figure 1 & Appendix 1). The hole intersected a wide zone of Ni-Cu mineralisation over 90m in width 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 221.9-223.75m, 228.7-236.9m, and 237.8-240.7m downhole occur within the interleaved metasedimentary units, with distinctive brecciated margins, indicating sulphide mobilisation (see Table 1). This textural observation, combined with the evidence of limited sulphide extension veining, suggested the mineralised zone intersected is remobilised and proximal to the intrusive source.
DHTEM is to be completed in RKDD023 to provide additional vectoring of the significant Ni-Cu mineralisation across the +90m mineralised zone.
Structural logging of RKDD023 will be undertaken before being sampled and submitted for assay.

RC Drilling Summary
A further 10 RC holes (RKRC018 – RKRC027) have been completed and assays received for 6 RC holes (RKRC015 – RKRC020) since the last report on RC drilling activity to the ASX on 28 July 2020 (see Figure 2). RC drillholes RKRC015 through RKRC020 intersected a highly prospective package of mafic and ultramafic intrusives above a metasedimentary and mafic granulite package. High MgO ultramafic, gabbronorite, and olivine gabbronorite intrusives contained variable mineralisation, dominantly trace to disseminated, with minor net-textured sulphide (see Figure 2 and Table 2).
Importantly, the RC drilling confirms the Mawson intrusive complex extends north and east of the Mawson Ni-Cu sulphide mineralisation, confirming the prospectivity for mineralised intrusives below the eastern aircore geochemical anomaly.
DHTEM is currently being undertaken on all completed RC drillholes.

To ensure the health and wellbeing of our employees and contractors, the Company has implemented a range of measures to minimise the risk of infection and rate of transmission of COVID-19. These measures include employees and contractors completing a COVID-19 Exposure Questionnaire, increased hygiene practices, restrictions on non-essential travel, establishing strong infection control systems and protocols across the business and facilitating remote working arrangements, where practicable. The Company will continue to monitor the formal requirements and guidance of State and Federal health authorities, and act accordingly.

• 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 |
