Lake Torrens Project - EL6416

• Farm in and joint venture agreement with subsidiary of Fortescue Ltd (signed June 2019) over EL 6416.

• Fortescue earned a 51% interest in EL 6416 by sole funding A$4 million plus GST on exploration expenditure.

• Fortescue elected to increase its holding to 80% subject to sole funding a further A$7million on exploration expenditure (i.e. increasing to $11 million in total).

• Tasman Currently holds a 49% interest, but that will be reduced to 20% if Fortescue expends $11 million.

• Co-located conductive / dense bodies may represent sulfide-rich lithologies.

• Western Mining drillhole BD2 (1982) was not an effective test of the target, being located approximately 500m away from the peak of the Residual Gravity anomaly.

• Fortescue has advised that it intends to undertake a drill program in CY 2026 to further explore the Titan West prospect.

• Vox Geophysics stated that co-located conductive and dense bodies at Titan West are consistent with the presence of a sulfide-rich lithology.

Titan & Bill's Lookout

Previous Drilling: Vulcan North Target Area

Two (2) deep holes (VUD018 and VUD 019) drilled by Fortescue to test Vulcan North gravity feature intersected wide zones of copper mineralisation in massive hematite breccia (ASX:TAS 30 June 2021) :

• VUD018 - 62m downhole* @ 0.55%^ Cu (including 13m @ 1.04% Cu + g/t Au)

• VUD019 - 321m downhole* @ 0.33%^ Cu (including 15m @ 1.25% Cu + 0.6 g/t Au)

• Strongly anomalous rare earth elements (up to 1.86% LREE over 9m) and anomalous gold and palladium

• VUD015 - nearby (drilled 2013 by Tasman) - 145m downhole* @ 0.49% Cu (including 52m at 0.87% Cu, and 21m at 1.69% Cu) (ASX:TAS 15 August 2013)

• True width not known, ^0.1% Cu cutoff

2D model (cross section) from SW to NE with the projected boreholes around Vulcan (thin, vertical black lines) and showing an interpreted 1- 2km wide, 5km deep conductive feeder zone to the North-East.

VUD 008 is represented by the thin black vertical line nearest the interpreted conductive feeder zone with the entire basement intersection (179.75m down hole) being mineralized and altered, and averaged 0.19% Cu, 0.10g/t Au (applying a 0.5 g/t cut), 0.02kg/t U3O8 and 68g/t Mo (ASX:TAS, 1 August 2025). and It also included a higher-grade zone from 910m (21m down hole) of 0.63% Cu, 0.28g/t Au, 0.02kg/t U3O8 107g/t Mo and was the first occurrence of copper-iron sulphide bornite in any drill hole, with a higher copper/ sulphur (Cu/S) ratio, a part of the mineralisation that is mined at Olympic Dam.

Parkinson Dam Drilling

ACM Defined Drill Targets on Magnetics:

• 2026 Planned Drilling – 6 undrilled targets following extensive geophysical surveys and reviews in 2024

Location of magnetic semi vertical pipe-shaped features on the image of the Vertical Gradient of RTP magnetics. The polygons outlining these features are relative to - 450m MSL.

• IP and Resistivity Survey –significant undrilled targets identified

• High density in-fill gravity survey identified many undrilled gravity anomalies adjacent to ACM drill targets, first identified from magnetics

• 5-6 proposed drill holes

Parkinson Dam

Drill Target 1 - IOCG - Shallow

==> picture [442 x 337] intentionally omitted <==

Dense material shown in gravity survey appears to cluster around edge of magnetic feature. Interpreted possible dense breccia forming a cylindrical shape typical for IOCG- type deposits such as Olympic Dam or Ernest Henry.

==> picture [64 x 24] intentionally omitted <==

Drill Target 2 (a) IOCG/Epithermal - Shallow

==> picture [442 x 337] intentionally omitted <==

Undrilled\pipe-like structure below elliptical demagnetized zone, interpreted as hydrothermal fluid feeder to shallow crustal epithermal field, approximately 460m diameter, from 32 metres below the surface to a depth of over 2000m.

==> picture [64 x 24] intentionally omitted <==

Drill Target 2 (b) Porphyry

==> picture [442 x 337] intentionally omitted <==

Target T2(b) is the newly interpreted 500-metre-wide radius, circular gravity structure directly beneath Tasman’s earlier drill hole PD 63. This drill hole intersected encountered high grade gold and silver (21m at 21g/t Au and 83g/t Ag, including 9m down hole at 31g/t Au & 152g/t Ag), that is interpreted as potentially being a porphyry intrusion at a depth of approximately 700 metres.

Disclaimer

The interpretations and conclusions reached in this presentation are based on current geological theory and the best evidence available to the authors at the time of writing.

It is the nature of all scientific conclusions that they are founded on an assessment of probabilities and, however high these probabilities might be, they make no claim for complete certainty.

Any economic decisions that might be taken on the basis of interpretations or conclusions contained in this report will therefore carry an element of risk.

It should not be assumed that the reported Exploration Results will result, with further exploration, in the definition of a Mineral Resource.

Mr Saleem has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity being undertaken to qualify as a Competent Person as defined in the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Mr Saleem consents to the inclusion in the report of the matters based on their information in the form and context in which it appears.

Note: Part of the information in this presentation for both the Parkinson Dam and Lake Torrens prospects was prepared and first disclosed under the JORC Code 2004. It has not been updated since to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported.

The Company is not aware of any material changes from the exploration results as previous reported and referenced.
