Lunnon Metals Limited Provides Last High Priority Assay Results from its Discovery Programme at the Baker Shoot, Part of the Kambalda Nickel Project
Lunnon Metals Limited provided the last high priority assay results from its discovery programme at the Baker Shoot, part of the Kambalda Nickel Project (KNP). The recently completed drilling programme was designed to infill and extend the initial JORC 2012 compliant Mineral Resource Estimate (MRE) announced on 14 June 2022. The MRE recorded an initial total of 15,800t nickel metal @ 2.8% Ni, which was discovered and defined inside 12 months of Lunnon Metals. All high priority diamond drill assay results have now been returned, having been delayed by the requirement to complete geotechnical logging and rock property testwork for future technical and mine planning studies. Significant intercepts from these last holes include (>1.0% Ni cut off): ECO22DD_018: 9.45m @ 6.94% Ni, 0.71% Cu, 0.15% Co, 1.24g/t Pd, 0.51g/t Pt (from 137.1m); 0.95m @ 7.06% Ni, 0.32% Cu, 0.15% Co, 1.19g/t Pd, 0.21g/t Pt (from 148.3m); 0.60m @ 10.53% Ni, 1.14% Cu, 0.16% Co, 1.22g/t Pd, 0.76g/t Pt (from 197.75m). ECO22DD_017: 0.75m @ 10.84% Ni, 0.25% Cu, 0.14% Co, 2.05g/t Pd, 1.38g/t Pt (from 211.2m). ECO22DD_013: 0.50m @ 6.72% Ni, 0.23% Cu, 0.11% Co, 1.28g/t Pd, 0.48g/t Pt (from 90.35m) and 0.50m @ 11.52% Ni, 0.46% Cu, 0.16% Co, 1.26g/t Pd, 0.43g/t Pt (from 93.5m). As has been observed throughout the programme, drilled widths approximate true widths although this is subject to final interpretation now that all drilling results have been receivedand are being modelled. Elevated cobalt, palladium and platinum values are once more recorded where the nickel grades are highest. Collar details and high priority assay results received for all remaining drill holes (above a 0.5% Ni and 1.0% Ni cut off) are presented in Annexures 1 and 2. In addition to the stand out intercepts highlighted at the start of this report, diamond holes ECO22DD_006, 008W1, 011, 013, 014, 017 and 077 fall on a number of different sections, which are updated below together with commentary on the reconciliation of these results with the June 2022 MRE. Section 6,531,220mN (G-H): Thicknesses modelled in the June 2022 MRE were reproduced in ECO22DD_013 with the grade comparable with predictions. This diamond hole was notable for the presence of narrower (~0.50m) high grade intercepts. The grade and thickness recorded in ECO22DD_014 were respectively slightly thinner and lower than the June 2022 MRE. Section 6,531,200mN (I-J): ECO22DD_018 was drilled across a number of sections. The significant intercepts reported fell on section 6,531,200mN as illustrated below in Figure 3. This drillhole has confirmed the results seen in adjacent holes ECO21DD_003 and ECO21RC_040. Mineralised surfaces PER03, BOF03 and BOF02 will be remodelled in this vicinity to incorporate these results. Drill hole ECO22DD_011 was drilled outside the June 2022 MRE with a narrow intercept recorded at the base ofsecond komatiitic flow position (BOF03). As illustrated below, this section line is drilled to a spacing that will facilitate close control of the modelling of the mineralised surfaces and the subsequent grade estimation. ECO22DD_018 continued on to section 6,531,180mN. An additional significant intercept of 1.25m @ 5.35% Ni was recorded on the MOB02 surface, the 45-degree dipping structure interpreted to have remobilised nickel from either, or both, of the basal contact and the base of the second komatiitic flow (BOF02). As illustrated above, section 6,531,180mN is drilled to a spacing that will assist close control of the modelling of the mineralised surfaces and the subsequent grade estimation. Section 6,531,160mN (M-N): ECO22DD_017 recorded a down dip and plunge intercept of significance. Remodelling of the BOF03 mineralised surface, shown in orange below on Figure 5 (i.e. between 1% Ni and 2.5% Ni estimated grade), will be necessary to accommodate the results of the infill and extensional programme, however the key zones of mineralised nickel sit to the west of this drill hole centred on ECO22RC_030 on the BOF03/eastern shear interface and ECO21RC_042 on the BOF02 interface with the western shear (MOB02). Again, as evident in the section below, section 6,531,160mN is drilled to a spacing that will assist close control of the modelling of the mineralised surfaces and the subsequent grade estimation. Section 6,531,080mN (Q-R): Approximately 80m to the south of section line M-N above, section 6,531,080mN is naturally drilled to a wider spacing than the section lines to the north which were the focus of the infill programme between July and September this year. Whilst down dip results from ECO22DD_008, historical hole SID319 and ECO22DD_009 indicate the mineralised nickel surface appears to continue to the east beyond the boundaries of the June 2022 MRE, current hole ECO22RC_077 (a diamond tail of an earlier RC pre-collar) and ECO22DD_008W1 recorded widths and grades similar to the June 2022 MRE. Positionally, the location of the BOF02 surface on this section will be reviewed and updated as part of the geological update to be completed in the December quarter. Section 6,530,960mN (U-V): Over 100m further south again and beyond the southern extremity of the Baker Shoot MRE and geological model, ECO22DD_007 and ECO22DD_006 recorded only weak mineralisation and no significant assays respectively. Although there was no mineralisation modelled this far south in the June 2022 MRE, the weak mineralisation observed in ECO22DD_007 and historical hole SID308 is located at the base of second komatiitic flow position, as is the bulk of the Baker MRE further to the north.
