Octagonal exploration activity update
HIGHLIGHTS
-
Diamond drillhole OCDD005 intersects intrusion/metasedimentary mixing zone at depth with magnetite and pyrrhotite the source of the AMT feature
-
Downhole EM (DHTEM) is scheduled for completion on OCDD005
-
New High-Power Fixed Loop Electro-Magnetics (HPFLTEM) survey over the entire Octagonal prospect designed to identify large sulphide bodies at depth
-
Future diamond drillhole planning pending outcome of HPFLTEM survey results
Legend Mining Limited (Legend) is pleased to provide an update on the diamond drilling and exploration activities at the Octagonal prospect within the Rockford Project, Fraser Range, Western Australia (see Figures 1 and 4).
Legend Executive Chair, Mr Mark Wilson said: “The AMT feature which hole 5 was designed to test turned out to be largely magnetite and pyrrhotite, which explains the lack of significant nickel-copper sulphide in this hole. Whilst we need to await the DHTEM results and structural analysis to appreciate the totality of information from this hole in particular, the results from the recent 4-hole programme have not reduced the overall prospectivity of Octagonal. These drillholes represent the first steps in unlocking the nickel-copper sulphide potential at Octagonal.
“From the information to date, it is becoming increasingly apparent that the best mineralisation is on the eastern flank of the prospect. This is further evidenced by the 4 conductors from DHTEM in hole 4.
“A decision has been made to conduct a large high powered EM survey over Octagonal with the design capacity to identify conductive responses below a depth of 600m. This is expected to deliver EM data which along with the seismic and other data sets will give us the next generation of diamond drill targets.”

TECHNICAL DISCUSSION
Exploration activities continue at the Octagonal prospect at the time of writing. Below is a summary of the exploration activities at Target Area B and Target Area C.
TARGET AREA B
Key takeaways from OCDD005 - Target Area B:
-
Intrusion extends at depth, with increased carbonate digestion proximal to the basal contact
-
Mixing zone of intrusion and metasediment supports the working model that the Octagonal Intrusive Complex (OIC) cracks into the surrounding metasediments
-
Sulphide decreased toward the west of the OIC, vectoring for mineralisation to targeting towards the eastern margins of the OIC
-
Critical structural data to further understand the controls of the OIC
-
OCDD005 provides an excellent DHTEM platform

ASX Announcement ASX:LEG
Diamond drillhole OCDD005 targeted a coincidental seismic and AMT zone of the Octagonal intrusion (see Figures 1 and 2). The drillhole was completed at a bottom of hole depth of 1,662m. The seismic zone and associated AMT feature are now confirmed as a mixing zone of digested metasediments and gabbroic intrusions. Indications are the AMT feature is derived from magnetite and pyrrhotite within this mixing zone. The drillhole intersected an upper suite of gabbronorites and leucocratic gabbronorites before intersecting a varied suite of higher MgO intrusion consisting of olivine gabbronorites, pyroxenites, and troctolites, with weakly mineralised zones. Extensive carbonate digestion in the mixing zone of intrusion and metasediments towards the basal contact supports the visual observations in OCDD004 that the Octagonal intrusion cracks into the underlying and surrounding metasediments. Reduced sulphide content in the drillhole suggests the sulphide content of the OIC decreases towards the west. This is an important indicator, with strong evidence from completed drilling suggesting that sulphide content of the OIC increases towards the eastern margins. This vectoring will allow for more focused drillhole targeting. OCDD005 will provide valuable structural information in an area of the OIC not previously drilled, allowing the integration of physical structural data with seismic responses to map folding. This folding is a primary control of the OIC geometry.
DHTEM is scheduled to be completed on OCDD005 at the time of writing.

ASX Announcement ASX:LEG
TARGET AREA C
DHTEM has been completed on drillhole OCDD004 and the associated models received (see Figures 1, 2 and Table 1). Four off-hole conductors have been identified, two interpreted to be relating to mineralisation inside the Octagonal intrusion and along the eastern hanging wall contact.
The observed increase in sulphide content and tenor in OCDD004 and DHTEM response has given encouragement to deploy a new High Power Fixed Loop Electro-Magnetics (HPFLTEM) across Octagonal, with the aim to identify large sulphide bodies at depth (see Figure 3). Forward modelling conducted during the HPFLTEM programme design suggests large sulphide accumulations should be detectable below 600m depth with the large loop, high current, and ultra-low frequency parameters of the purpose-designed survey. The survey will commence in the coming weeks.

Cautionary Statement: The sulphide percentage is a visual estimate of total sulphide. Visual estimates should never be considered a proxy or substitute for laboratory analysis where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations.
Legend regularly uses a portable XRF (pXRF) analyser to screen diamond drill core for mineralisation prior to cutting and sampling. This allows for understanding of the distribution of mineralisation prior to sampling to better ensure that the sampled core is representative of the type and style of mineralisation. Readings are obtained and recorded for future reference. The pXRF provides confirmation that mineralisation is present however it is not an accurate determination of the elemental concentration within the sample analysed. Limitations include; very small analysis window, possible inhomogeneous distribution of mineralisation, analytical penetration depth and possible effects from irregular rock surface. The pXRF readings are subject to confirmation by chemical analysis from an independent laboratory. Assay results are expected to be received for selected sample intervals during the September and December 2023 Quarters.

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. |
