5 October 2020 ASX Announcement
More Massive Nickel-Copper Sulphides at Mawson
-
RKDD027 intersects 26.25m of Nickel-Copper sulphide including:
-
15.45m massive sulphide across three zones
-
10.80m semi-massive and matrix sulphide across three zones
-
Multiple Nickel-Copper sulphide intercepts in RKDD024 and RKDD025
Legend Mining Limited (Legend) is pleased to report on observations from diamond drillholes RKDD024-027 and results and observations from RC drillholes RKRC022–034 at the Mawson Prospect within the Rockford Project, Fraser Range, Western Australia (See Figure 4). News flow from the project has been impacted by delays in assay turnaround and downhole EM contractor availability has impacted the site work programmes. The details are discussed in the body of this report.

Legend Managing Director Mr Mark Wilson said: “The content of the technical discussion within this announcement confirms that work has continued apace at Mawson since our last Mawson announcement on 8 September.
“The material widths of the intercepts in hole 27 speak to our confidence of the size potential of the Mawson system, whilst the information from the other reported holes is adding to the bigger picture.
“We are planning to release a 3D model of Mawson shortly which will visually depict the scale potential of Mawson in 3D for the first time. This model will aggregate data interpretations from the detailed gravity, magnetics, geochemistry and structural geology.”

Diamond Drilling Summary
RKDD027 is part of an infill diamond drill program designed to extend/close off known Ni-Cu mineralisation at the Mawson massive Ni-Cu sulphide discovery (See Figure 1). Additional drilling is required to the east of the western aircore geochemical anomaly based on the current interpretation of Mawson. RKDD027 was targeting the extension of known mineralisation in RKDD017 and was planned for a 20m separation from RKDD017. RKDD027 remained straighter than planned during drilling, resulting in an actual separation of 23.8m at 230m downhole. RKDD027 intersected 26.25m of Ni-Cu sulphide including three zones of massive sulphide totalling 15.45m (162.0-174.9m, 175.6-176.45m, and 231.8-233.5m downhole) and three zones of semimassive and matrix sulphide totalling 10.8m (174.9-175.6m, 188.85-195.2m, and 215.8-219.55m downhole). A disseminated zone was also intersected from 153.7-162.0m downhole (See Table 1, Figure 2, and Appendix 2). RKDD027 confirms that the massive sulphide continues to the west on this section. DHTEM is now scheduled for RKDD027.

RKDD025 was designed to target a very strong 20,000-25,000S DHTEM plate identified above RKDD023. The RKDD025 was designed with a 40m separation from RKDD023. The hole intersected a dominantly gabbronorite and olivine gabbronorite before finishing in metasediments. Narrow zones of massive sulphide were intersected at 217.02m-217.28 and 223.01m-223.31m, a brecciated sulphide zone from 218.6m-219.14m, and a disseminated sulphide zone from 160.0m217.02m. Visual assessment suggests the hole did not intersect the best part of the DHTEM conductor target. DHTEM has since been completed and results confirmed the upper extremity of the original plate was intersected. Subsequent DHTEM data has defined the main conductive plate below and south of RKDD025.

RKDD025 Disseminated Ni-Cu Sulphide from 170m, NQ2
RKDD026 was a structural hole designed to target the northern vector of the sulphide extension veins logged in the Mawson discovery zone. The hole intersected the interpreted western margin of the Mawson Intrusive Complex, defined by a graphite-rich gabbronorite interleaved with a metasedimentary sequence and norites as well as a pegmatite zone before finishing in a meta-BIF and metapsammite package. The identification of graphite so shallow in the hole further explains the challenges of surface EM as a direct mineralisation targeting tool in this environment.
RKDD024 was designed to test the southern extension of the Mawson Intrusion, including a discrete gravity feature modelled from the processing of the detailed gravity completed across Mawson (See Figure 1). The hole intersected an upper gabbronorite unit with blebby and disseminated Ni-Cu sulphide from 106.4-124.3m, followed by a dominantly norite zone with minor troctolite to 236.1m, before intersecting a mixed norite and meta-BIF package to 275.55m. The remainder of the hole was weakly mineralised norite intrusion with dominantly disseminated plus minor stringer vein Ni-Cu sulphides to 327.6m, finishing in barren norite at 367.2m.

Structural logging of RKDD023, RKDD025, and RKDD026 has allowed for further development of the Mawson geological model, which will result in more focused drill targeting. As previously reported to the ASX on 8 September 2020, the brecciated and melt migration sulphide textures observed in RKDD023, combined with the evidence of limited sulphide extension veining, suggested the mineralised zone intersected is remobilised. Examples of the sulphide textures can be seen below. In addition, a massive Ni-Cu sulphide sample from 230.5m downhole of RKDD023 was analysed by the Bruker M4 TORNADO by Portable Spectral Services. The resulting image clearly identifies the pentlandite (Ni) and chalcopyrite (Cu) sulphides within the sample, as well as the textural relationships between the sulphide species, in line with the structural interpretations.

The DHTEM contractor has returned to site after a 4 week delay due to the current high volume of outstanding jobs for other clients. DHTEM is currently underway for diamond holes RKDD024 – 027 with results awaited from hole RKDD025. The crews will remain on site at Mawson to complete the DHTEM of the completed diamond and RC drillholes.
RKDD023-026 have been sampled and submitted for assay. Turn-around from the laboratory is currently 5-6 weeks from receival of samples due to the high volume currently being experienced by the laboratory.
RC Drilling Summary
A further 7 RC holes (RKRC028 – RKRC034) have been completed and assays received for 1 hole since the last report on RC drilling activity to the ASX on 8 September 2020 (see Figure 3 and Table 2). RC drillholes RKRC028 through RKRC031 intersected a metasedimentary assemblage of metaBIF and metapelites-psammites and mafic granulites. These holes will now be utilised as DHTEM platforms for off hole targeting. RKRC032 – RKRC034 are currently being logged. RKRC022 intersected a mineralised gabbronorite with disseminated to net-textured sulphide above a metaBIF unit. This is a highly encouraging target given the similarities of the geological setting when compared to the massive sulphide mineralisation of the initial Mawson discovery under the western aircore geochemical anomaly.
Importantly, the RC drilling continues to confirm the Mawson Intrusion extends north and east of the known Mawson Ni-Cu sulphide mineralisation, confirming the prospectivity for mineralised intrusives below the eastern aircore geochemical anomaly. Additionally, the geological information is evolving the Mawson geological model and focusing diamond drill targeting.
DHTEM is planned on completed RC drillholes, with surveys in RKRC020 in progress as at the writing of this report.
