VTEM Survey Preliminary Data Highlights:
-
Preliminary line data indicates mid to late channel bedrock conductors at several new undrilled locations.
-
At the new Droughtmaster Prospect a strong late time conductor identified on the southern end of the Magna Lynn VTEM survey and coincident with undrilled historical copper workings.
-
At the new Speckle Park Prospect a moderate late time conductor has been identified over 3 consecutive 200m spaced VTEM lines .
-
At the new Charolais Prospect a new conductor over five consecutive 200m spaced VTEM lines has been defined. No previous exploration has been recorded over this area.
-
The 435 line km aerial VTEM survey was completed over a >20km section of the Magna Lynn southern corridor which stretches for over 75km of essentially unexplored terrain south of the Nil Desperandum deposit.
-
The VTEM survey was funded by the Queensland government Collaborative Exploration Incentive ( CEI ) grant program.
-
VTEM has been highly effective in the Greater Duchess region for identifying Iron Oxide Copper Gold mineralisation, exemplified by the discovery of the Mohawk Prospect in 2024 (see ASX release 5 August 2024).
The Company’s Managing Director, Rob Watkins commented:
“The extensive 435 line km VTEM survey targeting the extremely underexplored 75km southern Magna Lynn corridor south of Nil Desperandum has unearthed several new high priority conductors at the newly named Droughtmaster, Speckle Park and Charolais Prospects . We thank the Queensland government for their support in funding regional exploration programs in the NW minerals province of Queensland. VTEM has been highly successful in the Greater Duchess region highlighted by the recent discovery of the Mohawk Prospect in late 2024, where the first drill hole recorded 21m @ 2.0% Cu, 0.6g/t Au. We look forward to receiving the processed VTEM data and ground truthing the significance of these newly identified prospects. First pass surface field exploration programs will involve soil and rock geochemistry and mapping followed by first pass drill programs.”

GREATER DUCHESS COPPER GOLD PROJECT
An extensive aerial VTEM survey was completed over the Magna Lynn Southern corridor south of Nil Desperandum, where a total of 435 line km of helicopter VTEM surveying was undertaken at 200m line spacing at three separate locations named St Andrews, Magna Lynn and Makbat (Figure 1).

The VTEM survey was completed by UTS Geophysics and supervised by ExploreGeo. Detailed processing of the VTEM data is underway and is estimated to take approximately one month to receive the final data and images. Due to the requirement to validate and process the data,

only preliminary line data observations can be presented below which have been provided by independent consultant ExploreGeo. These are also tabulated in Table 1 of Appendix 1.
St ANDREWS VTEM SURVEY
The St Andrews VTEM survey consisted of twelve VTEM lines at 200m spacing targeting a major fault conjugate confluence zone and stratigraphic strike change evident in aeromagnetics (Figure 3). The St Andrews Fault is a regional scale NE striking fault that parallels the adjacent Railway Fault that is interpreted to be an important control on the Duchess and Ivanhoe IOCG deposits located 8km to the NE.
SPECKLE PARK PROSPECT
A moderate mid channel conductor has been detected at the newly named Speckle Park Prospect traceable across three consecutive 200m spaced VTEM lines (Figure 2). The anomaly is located under shallow alluvial cover and is located on a major geological boundary between the highly magnetic Corella Formation to the east and potentially the Argylla Formation to the west. This major geological contact is considered to be a highly favourable location for IOCG mineralisation in the district. The Speckle Park VTEM conductors are associated with a discrete 900 nT magnetic anomaly as shown in Figure 2.

Historical exploration in this area was conducted by Mount Isa Mines Limited ( MIM ) in 1990 and consisted of vertical mini RAB drilling on a 300m x 100m grid with a single sample collected at the bottom of each hole. Average depth of the drilling was only 7m and it is unclear whether all holes reached basement below the cover sequence. A maximum result of 2,000 ppm copper from bottom of hole was intersected in STANDREW078 (see publicly available report CR021583 accessible via Geological Survey of Queensland). Full results from the MIM historical RAB drilling program are presented in Table 2 of Appendix 1.
Carnaby will complete first pass reconnaissance of the VTEM anomaly area and undertake early stage mapping and sampling to investigate the significance of this new prospect and the likely source of the VTEM conductor prior to first pass drill programs or ground EM.
MAGNA LYNN VTEM SURVEY
The Magna Lynn VTEM survey was the largest of the three VTEM survey areas and targeted a 20km strike length of the interpreted southern extension of the Nil Desperandum IOCG structural and stratigraphic corridor (Figure 1). This potentially mineralised corridor is essentially unexplored using modern day exploration techniques and very little or no historical exploration has been recorded in this entire area (Figure 1).
A total of 100 consecutive VTEM lines were flown at 200m line spacing covering an area of approximately 77km[2] of the Magna Lynn corridor (Figure 3).
Preliminary analysis of the VTEM data has highlighted at least two areas of apparent basement conductors, each evident over several consecutive 200m spaced VTEM lines as discussed below.
Carnaby expects to receive the final processed VTEM data in approximately one month.
DROUGHTMASTER PROSPECT
A strong late channel conductor has been detected at the newly named Droughtmaster Prospect (Figure 3). The basement conductor is traceable over three consecutive 200m spaced VTEM lines and is spatially coincident with historical copper workings. The copper workings are traceable over 400m of strike with recent rock chip samples collected by Carnaby assaying up to 10% copper (see ASX release 4 July 2024).
No previous systematic exploration has been recorded in this area, including no historical soil sampling or drilling. Carnaby will initially complete first pass reconnaissance programs of mapping, soils and rock chip sampling to verify the significance of this new prospect and the likely source of the strong VTEM conductor prior to a first pass drill program.

CHAROLAIS PROSPECT
A weak to moderate mid channel conductor has been detected at the newly named Charolais Prospect (Figure 3). The basement conductor is traceable over 1km of strike across five consecutive 200m spaced VTEM lines.

No historical exploration has been recorded in this entire area.
The Charolais Prospect is located within the Magna Lynn interpreted structural and stratigraphic IOCG corridor. The Prospect is coincident with a high magnetic unit and favourably located at a major regional scale bend in the stratigraphy from NW striking to NS striking (Figure 3).
Carnaby will complete first pass reconnaissance to the VTEM anomaly and undertake mapping, soils and rock chip sampling to verify the significance of this new prospect and the likely source of the VTEM conductor.
MAKBAT VTEM SURVEY
The Makbat VTEM survey consisted of six VTEM lines at 200m spacing targeting a large previously unexplored circular coincident magnetic and gravity target (Figure 1). Preliminary interpretation of a circular conductor feature evident in the VTEM results and coincident with the circular magnetic and gravity anomaly is a surficial source however, further investigations are required.
VTEM RESULTS DISCUSSION
It should be noted that the relative strength of the VTEM conductors is not necessarily a direct correlation with copper grades because typical copper sulphide (chalcopyrite) is magnitudes less conductive than gangue sulphide (pyrrhotite). This is demonstrable by the previous orientation VTEM lines over the Nil Desperandum Prospect, which generated only a weak to moderate late channel conductor over the known deposit (see ASX release 21 October 2024). Equally, pyrrhotite is not always present as a gangue sulphide mineral in IOCG deposits where pyrite is often the main gangue sulphide, which is not conductive. Therefore, a moderate level or even weak VTEM conductor can be very significant.
The Greater Duchess deposits also have distinct footwall and hangingwall magnetite alteration which can also be highly conductive, as such further investigations are required to determine the exact root cause of the conductors that have been defined.
However, the overwhelming finding from all the electrical geophysics completed to date in the region, including aerial, ground and downhole EM methods, is that electrical geophysics has been working exceptionally well at locating copper bearing mineralisation at Greater Duchess, with a 100% success rate to date. This bodes well for the VTEM conductors that have been generated by the survey that are yet to be drilled, and we look forward to receiving the processed VTEM data and completing first pass field programs and drilling of these high potential targets.

APPENDIX TWO
JORC Code, 2012 Edition | ‘Table 1’ Report
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (e.g., cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). 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 (eg submarine nodules) may warrant disclosure of detailed information. |
• The conductors reported are preliminary interpretations of preliminary data provided to the company by ExploreGeo Pty Ltd. • This survey was flown by completed by UTS Geophysics Pty Ltd using a Versatile Time- Domain Electromagnetic (VTEM Max) system. • VTEM Max was flown covering 435 line km with 200m east-west line spacing and a sensor height of 35mAGL. • Historic Rotary Air Blast (RAB) holes were sampled by taking 2-3kg of uncontaminated bedrock material from the final 1.5m of each drill hole. |
| Drilling techniques |
• Drill type (e.g., core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method,etc). |
• Not applicable to geophysics. • Historic Rotary Air Blast (RAB) holes in Appendix 1, Table 2 were drilled to an average depth of 7m. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
• Not applicable to geophysics. • Details on historic RAB sample recovery and methods were not reported. |
| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. |
• Not applicable to geophysics. • Historic RAB chips were logged on site with lithology, alteration and mineralisation recorded. |
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
• Not applicable to geophysics. • Historic sample collection methodology and QAQC procedures were not reported. |

| Acknowledgment and appraisal of exploration by other parties. |
• Acknowledgment and appraisal of exploration by other parties. |
• There has been exploration work conducted over the Greater Duchess project regions for over a century by previous explorers. The project comes with significant geoscientific information which covers the tenements and general region, including: a compiled database of 6658 drill hole (exploration and near-mine), 60,300 drilling assays and over 50,000 soils and stream sediment geochemistry results. This previous exploration work is understood to have been undertaken to an industry accepted standard and will be assessed in further detail as the projects are developed. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The Greater Duchess Project is in the Mary Kathleen domain of the eastern Fold Belt, Mount Isa Inlier. The Eastern Fold Belt is well known for copper, gold and copper-gold deposits; generally considered variants of IOCG deposits. The region hosts several long-lived mines and numerous historical workings. Deposits are structurally controlled, forming proximal to district-scale structures which are observable in mapped geology and geophysical images. Local controls on the distribution of mineralisation at the prospect scale can be more variable and is understood to be dependent on lithological domains present at the local-scale, and orientation with respect to structures and the stress-field during D3/D4 deformation, associated with mineralisation. Most of the mineralised zones are primary with chalcopyrite being the main copper bearing mineral. Portions of the Mount Hope deposit have been weathered resulting in the formation of secondary sulphide minerals including chalcocite. • The Magna Lynn Southern Corridor is comprised of a central package of NNW trending stratigraphy including the Leichhardt Volcanics, Magna Lynn Metabasalt, Argylla Formation and Stanbroke Sandstone. These units are bounded to the west by the older Kalkadoon Granite and to the east by the younger Birds Well and One Tree Granite Intrusions. NNW trending faults have been interpreted throughout the tenement as well as smaller NS fault splays. Occasional major NE and NW trending faults have been interpreted to transect the northern half of the corridor. |

| tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
||
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g., cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearlystated. |
• Historic RAB results are reported from a single, 1.5m end of hole sample taken at each hole. |
| Average Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g., ‘down hole length, true width not known’). |
• The geometry of mineralisation with respect to the historic RAB drilling is unknown. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• See the body of the announcement. |
| Balanced reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reportingof Exploration Results. |
• As discussed in the announcement |
