ASX ANNOUNCEMENT

02 MAY 2022

NMR awarded a $220,000 EIS grant to drill a follow-up hole at its Helios project.

Highlights:

  • NMR has been awarded $220,000 by the Western Australian Department of Mines, Industry Regulation and Safety (DMIRS) as part of its Exploration Incentive Scheme (EIS).

  • The co-funding will be used to drill a second, follow-up hole into the "Helios" target in the Nullarbor where NMR has just completed its first diamond drill hole into the basement rocks there (results to be announced soon).

  • The drilling will significantly increase NMR's knowledge of the Helios target and is the critical next step for the company at this exciting and developing project.

  • Second EIS grant awarded in the last 12-month period. NMR was also awarded a grant in May 2021 to perform diamond drilling at Music Well gold project

Native Mineral Resources Holdings Limited (ASX: NMR) ("NMR" the "Company"), is pleased to announce that it has been awarded $220,000 in the highly competitive Exploration Incentive Scheme (EIS). The grant will support further exploration diamond drilling at the Company's Helios Ni - Cu target area located in the Madura Province, approximately 200 kilometres northeast of Rawlinna in the Nullarbor region of Western Australia(Figure 1).

NMR has already obtained positive results from forward modelling of its high-resolution drone-based magnetics data and, based on these findings, has completed a single diamond drill hole to a depth of 500m. The results of this drilling are to be announced shortly. The planned EIS co-funded drill hole has been specifically designed to follow up on current results.

The magnetic high at the centre of the target area is interpreted to be magnetite-bearing magmatic rocks that can be associated with the formation of Ni or Cu deposits such as the Nova-Bollinger deposit in the nearby Frazer Range or the ca.1590 Ma Olympic Dam IOCG deposit in the Gawler Craton of South Australia.

Prior to undertaking the EIS co-funded drilling, NMR is planning on completing a ground-based, moving loop electromagnetic survey (MLEM) over the highest priority part of the target located approximately 500m north of its current drill site. The final drill collar will be planned based on the outcomes of the EM survey.

Management Commentary

NMR's Managing Director, Blake Cannavo, commented: "The team at NMR thank the DMIRS for supporting exploration in such a remote but exciting exploration frontier in Western Australia. The region has had very little drilling and this funding will help NMR contribute to the growing knowledge of the basement rocks in this region. The drilling is the essential next step for NMR following the successful completion of its first diamond hole at Helios in April 2022. We are also excited that the DMIRS supports NMR's brave exploration plan for this part of Western Australia as there is growing opportunity to uncover a significant mineral occurrence here.

This follows our successful EIS co-funded diamond drilling campaign in our other tenement area in WA (Music Well (E37/1362 and E37/1363)) where NMR was awarded $67,945 in 2021 by the DMIRS."

The Helios target is the northernmost of the three new and exciting tenements on the underexplored Nullarbor in SE Western Australia. NMR is targeting intrusion-related Ni or Cu mineralisation in a setting similar to the Nova-Bollinger mine (located to the SW of the Helios target as shown on map above). The Helios target lies approximately 100km north of the E-W oriented trans-Nullarbor railway line.

Drilling to target potential for intrusion-related Nickel and/or Copper mineralisation

NMR completed a 50m line spacing drone-based magnetic survey over its Helios target located in SE western Australia. A single RC and Diamond drill hole was planned to follow-up on positive results from the magnetics. The drill hole (HELIOS_DDH001) has just been completed, with most samples already cut and sent for assay and geochemical analysis. The results of this drilling will be released shortly. This second, EIS co-funded drill hole proposed here, is planned to follow up on the existing hole and will be completed following an additional geophysical survey over the northern part of the central high magnetic anomaly.

NMR are targeting Nova-Bollinger-style Ni or Cu, intrusion related mineralisation below a major magnetic anomaly that has been successfully imaged and modelled in the recent geophysical survey.

Forward modelling of magnetics results helping to define drill targets

The results obtained from the high-resolution drone magnetics have been forward modelled to assist in pinpointing the best possible drill hole location. Specifically, the forward modelling was used to develop more precise interpretations of the depth to the basement rocks, the depth to the magnetic target, and the magnetic susceptibility properties of the target rocks. The forward modelling was undertaken by Brisbane-based Geo Discovery Group Pty Ltd.

The results of the modelling are shown inFigure 4 andFigure 5.The seven modelled bodies included in the forward model are shown in their position as viewed from above. The two bodies shown in purple, C1 and C2, represent the two objects with the highest modelled magnetic susceptibility values of 0.17 and 0.2 SI units respectively. The EIS co-funded drill hole (HELIOS_DDH002) will be used to test both targets C1 and C2. C1 and C2 are modelled as two separate bodies, yet they may represent a single, relatively high susceptibility body located over 100m below the central part of the Helios eye-shaped structure. The modelled susceptibility values of over 0.17 SI units are consistent with magnetite-bearing rocks. NMR is currently planning an EM survey over the northern part of the C1 and C2 anomalies to pinpoint the location of potential conductive zones extending north and to the south of the current HELIOS_DDH001 drilling.

Targets C1 and C2 lie beneath the highest signal in the drone-based magnetics. The base image is the TMI RTP 1VD image generated from the drone-based magnetic data.

Figure B is an interpretation showing the two geometric bodies modelled in A as one, graded (relative to magnetic susceptibility) body plunging to the west (right). The EIS co-funded drill hole aims to drill into the base of the modelled unit.

Native Mineral Resources manage three granted tenements and two applications in the critically under-explored, but highly attractive Madura Province located on the Western Nullarbor (Western Australia)(Figure1). The region is growing in interest with many new exploration tenement applications by companies including Rio Tinto, BHP Nickel West and Maria Resources (Strategic Elements (ASX: SOR)). Limited drilling has already
