GOLDEN CROWN AND DUMBARTON
CONCEPTUAL PITS AND LIKELIHOOD OF POTENTIAL EXPLOITATION
The Golden Crown MRE is to a depth of approximately 50m and Dumbarton MRE is to a depth of approximately 80m. Both resources utilise a 0.5 g/t Au cut-off grade and are reported within conceptual pits based on a gold price of AU$6,500 per ounce Au and using current Leonora costs. The 0.5 g/t Au cut-off grade is reflective of the estimated cost required to haul and mill material at the anticipated M2M gold processing facility (ASX:M2M Announcement, 15 December 2025) at Malcolm (Figure 1). Golden Crown lies in close proximity to the proposed milling facility, while Dumbarton is situated within 10km, resulting in minimal haulage requirements for both deposits.

Use of the conceptual pit criteria enables the MREs to have a likelihood of potential exploitation, as required by JORC 2012.
JORC Table 1 (Sections 1, 2 and 3) for Golden Crown and Dumbarton are included as Annexure D to this announcement.

Mineral Resource Estimate Methodology
Carras Mining Pty Ltd (“CMPL”) was commissioned by Mt Malcolm Mines ("M2M") to produce the Maiden Mineral Resource Estimate ("MRE") for both the Golden Crown and Dumbarton prospects.
The acquisition of data used in the MREs was consistent with industry good practice and work was carried out by senior geologists with extensive geological experience. At all times, processes at site were coordinated and supervised by onsite geologists.
Dr. Carras of CMPL was involved with all aspects of interpretation and evaluation and also carried out site visits.
GOLDEN CROWN
1. Geological Interpretation
Recent geological interpretation at Golden Crown has established the significance of both subvertical and flat structures where:
-
High grade (> 2 g/t Au) mineralisation is typically associated with northwest striking and subvertically dipping quartz veining.
-
Lower grade (> 0.5 g/t Au to 2 g/t Au) mineralisation is typically associated with flat dipping structures to the northeast.
This interpretation has been used as the basis of the Maiden MRE.
High-Grade Lodes in Sheared Felsic/Intermediate Volcanics
At Golden Crown the mineralised corridor is currently defined within a rectangular area of 150m (NW-SE) x 200m (NE-SW), supported by bulk sampling and RC drilling confirming high-grade continuity and is open down-dip and along strike (Figure 4).
The Golden Crown drillhole database comprises 104 RC drillholes for 5,843 metres of drilling, of which 100 holes were completed by M2M. The remaining 4 RC drillholes were drilled prior to the M2M float.
There are 47 RAB drillholes in the database which have been used minimally in the resource to aid in the interpretation, and on one occasion, a low grade run of values was used where it is strongly supported by RC drilling. In general, the use of RAB drilling was not material, as specified by JORC 2012.
Mineralisation Styles
Gold mineralisation is shear controlled and veins comprise quartz ±sulphides. Gold mineralisation is localised in confirmed steep, stacked quartz lodes that show pinching and swelling, as well as within shallow flat dipping structures. Both styles of mineralisation are typical of an orogenic lode-gold system.

2. Estimation Methodology
The following outlines the estimation and modelling technique used for producing the Maiden MRE for the Golden Crown prospect in accordance with JORC 2012 criteria.
Surfaces
Surfaces were produced for the following:
-
Surface topography based on a LiDAR survey
-
Base of Complete Oxidation (“BOCO”), Base of Upper Transition (“UTZ”) and Top of Fresh Rock (“TOFR”) were all based on geological logging
Sample Lengths
The majority of sample data was 1m lengths and length weighting was used when modelling the deposit.
Top Cuts
The following top cuts were used:
Quartz Veins Striking Northwest
For subvertical quartz vein structures proximal to the high grade bulk sampling pit, a top cut of 50 g/t Au was used based on an inflection in the higher end of the assay distribution. For other subvertical quartz vein structures, a top cut of 20 g/t Au was used.
Quartz veins near bulk sampling pit:
4 values (111 g/t Au, 65.66 g/t Au, 61.39 g/t Au, 53.28 g/t Au) were cut to 50g/t Au.
Quartz veins in other areas:
2 values (29.29g/t Au and 29.83 g/t Au) were cut to 20g/t.
The overall percentage metal cut of the assays within the quartz veins was 9%.
The consistent high gold values obtained throughout the drilling are indicative of the coarse gold associated with the Golden Crown deposit as seen in the bulk sampling exercise, carried out by M2M during 2024-2025 (ASX:M2M Releases). This is a motivating factor in the proposed close spaced shallow drilling into the subvertical high grade quartz structures.
Page 12
Flat Dipping Structures to the Northeast
For flat dipping structures to the northeast, a top cut of 6 g/t Au was used.
1 value (8.6 g/t Au) cut to 6 g/t Au.
The overall percentage metal cut of the assays within the flat structures was 2%.
Intersection Selection Parameters
Mineralised intersections* were produced based on the following parameters:
-
2m minimum width down hole (approximately 2m horizontally)
-
0.5m edge added to the top and bottom of the intersection. (This is a shape dilution applicable to a methodology where mining will be based on defining the edge of the mineralisation using a cut-off grade and there is not a visual geological boundary.)
-
2 g/t Au cut-off grade for subvertical quartz veins striking northwest
-
0.5 g/t Au cut-off grade for flat dipping structures to the northeast
The intersections have not been diluted for mining (as would be required for a reserve).
Mineralisation within quartz veins structures was limited to 10m in the subvertical direction and 5m along strike of a drillhole.
The list of intersections are included in Annexure B.
Geological Sections
Selected geological sections showing the interpreted structures are attached in Annexure C.
Interpolation
Interpolation used an inverse distance squared (ID2) method with search size and direction based on normalised variograms with a range of up to 15m. The result was verified by inverse distance cubed (ID3).
*Note: Intersections refer to mineralised intervals which include edge dilution. Intercepts refer to mineralised intervals which do not include edge dilution
Page 13
For ID2 the following parameters were used:
-
A minimum number of samples of 2 and a maximum number of samples of 12
-
The discretisation parameters were 2E x 2N x 1RL
-
The following search radii were used:
-
Quartz veins striking northwest:
- 10m along strike, 10m down dip, 2m down hole (modified slightly for some shapes depending on their geometry)
-
Flat dipping structures to the northeast
- 15m along strike, 10m down dip, 3m down hole (modified slightly for some shapes depending on their geometry)
-
Note: for blocks that were not filled, the parameters were relaxed and the search radii were increased.
The block size used was 1m E x 1m N x 1m RL to ensure adequate representation of narrow lodes, however only mineralisation within full shapes was reported.
Bulk Density
Following bulk density analysis by ALS Laboratories, the bulk densities used were:
Oxide: 2.0 t/m3 Upper Transition: 2.4 t/m3 Lower Transition: 2.7 t/m3 Fresh: 3.0 t/m3
Currently there is approximately 2,500 tonnes of material at surface allocated to stockpiles relating to the bulk sampling pit. This tonnage has not been included in the resource.
Bulk Sampling Outcome
The bulk sampling program at Golden Crown delivered high and consistent gravity recoveries, totalling 362 ounces Gold Dore' from 979 WMT, with batch grades peaking at 22.4 g/t Au[1] . These results confirm the effectiveness of the gravity recovery and high-grade nature of the mineralisation.
The volume and grade mined within the bulk sampling exercise has been removed from the current MRE.
1M2M- ASX: Metallurgical Recovery up to 22.4 g/t Au, 3 March 2025. These figures represent metallurgical test outcomes from bulk sample processing and should not be interpreted as Mineral Resource or Ore Reserve grades under the JORC Code (2012).
Page 14
Historic Gold Production
Historic gold production at Golden Crown is reported as 1,720 oz Au @ 29 g/t mined (1899-1904) (Ref: List of Cancelled Gold Mining Leases, Kelly 1954) and confirms the robustness of grade, validated by M2M drilling and bulk sampling.
An inspection of mined areas shows historic production has come from various small workings outside of the current interpretation and does not impact the current MRE, much of which is deeper.
Classification
The MRE was classified as Indicated and Inferred to represent confidence and risk. Classification was based on drill hole spacing, geological and grade continuity.
Mineralisation within the close spaced drilling (up to ~15m) was classified as Indicated. Other mineralisation was classified as Inferred
The Inferred MRE has a lower level of confidence than the Indicated MRE. It is reasonably expected that the majority of Inferred MRE could be upgraded to Indicated MRE with continued exploration. See figures below:

DUMBARTON
3. Geological Interpretation
The Dumbarton Prospect is located approximately 10km southeast of Golden Crown and sits within the Malcolm Greenstone Belt of the Kurnalpi Terrane, an Archaean greenstone sequence renowned for hosting numerous significant gold deposits.
Gold mineralisation at Dumbarton occurs along approximately 900m of strike within a regional shear zone, where mineralised quartz veins are hosted in carbonated basalt and intrusive dolerite. The lodes comprise quartz–carbonate veins containing disseminated pyrite and arsenopyrite. Mineralisation is consistently associated with quartz veining developed within strongly sheared, foliated and carbonate-altered basalt, typically located immediately adjacent to dolerite contacts.
The Dumbarton drillhole database comprises a total of 99 drillholes, including 51 RC holes for 4,776 metres and 5 AC holes for 350 metres and 43 RAB holes for 1,906 metres. Of the RC drilling, M2M completed 37 holes for 3,950 metres.
The RAB drillholes in the database have been used minimally in the resource to aid in the interpretation. In general, the use of RAB drilling was not material, as specified by JORC 2012.
Page 16
==> picture [486 x 365] intentionally omitted <==
Figure 13. Dumbarton Plan View.
Estimation Methodology
The following outlines the estimation and modelling technique used for producing the Maiden MRE for the Dumbarton prospect in accordance with JORC 2012 criteria.
Surfaces
Surfaces were produced for the following:
-
Topography (TOPO) based on surveyed drillhole collar locations
-
Transported Material, Bottom of Oxidation (BOCO) and Top of Fresh Rock (TOFR) were all based on geological logging
Sample Lengths
The majority of sample data was 1m lengths and length weighting was used when modelling the deposit.
Top Cuts
A high grade cut was not required. The maximum grade was 10.6 g/t Au.
Page 17
Intersection Selection Parameters
Mineralised intersections were produced based on the following parameters:
-
2m minimum width down hole (approximately 2m horizontally)
-
0.5m edge added to the top and bottom of the intersection. (This is a shape dilution applicable to a methodology where mining will be based on defining the edge of the mineralisation using a cut-off grade and there is not a visual geological boundary.)
-
0.5 g/t Au cut-off grade
The intersections have not been diluted for mining (as would be required for a reserve).
The intersections are included in Annexure B.
Geological Sections
Selected geological sections showing the interpreted structures are attached in Annexure C.
Interpolation
Interpolation used an inverse distance squared (ID2) method with search size and direction based on normalised variograms with a range of up to 25m. The result was verified by inverse distance cubed (ID3).
For ID2 the following parameters were used:
-
A minimum number of samples of 2 and a maximum number of samples of 16
-
The discretisation parameters were 2E x 1N x 1RL
-
The following search radii were used:
-
25m along strike, 25m down dip, 3m down hole (modified slightly for some shapes depending on their geometry).
-
Note: for blocks that were not filled, the parameters were relaxed and the search radii were increased.
The block size used was 2m E x 1m N x 1m RL to ensure adequate representation of narrow lodes.
Bulk Density
Following bulk density analysis by GTI Perth Laboratories, the bulk densities used were:
| Transported: | 1.8 | t/m3 |
|---|---|---|
| Oxide: | 2.3 | t/m3 |
| Transition: | 2.5 | t/m3 |
| Fresh: | 2.7 | t/m3 |
Page 18
Historic Gold Production
Historic gold production at Dumbarton is reported as 210.58 oz Au @ 17 g/t mined (1899-1904) ( Ref: List of Cancelled Gold Mining Leases, Kelly 1954). Mineralisation associated with this material has not been intersected by the current drilling and therefore depletion is not required.
Classification
The MRE was classified as Indicated and Inferred to represent confidence and risk. Classification was based on drill hole spacing, geological and grade continuity.
Mineralisation within the close spaced drilling (up to ~20m) was classified as Indicated. Other mineralisation was classified as Inferred.
All fresh mineralisation (9% of the MRE) was classified as Inferred as the samples submitted for fresh rock were not of high enough grade (due to limited higher grade sample availability) to determine a robust recovery and further metallurgical testwork on fresh rock samples will be carried out.
The Inferred MRE has a lower level of confidence than the Indicated MRE. It is reasonably expected that the majority of Inferred MRE could be upgraded to Indicated MRE with continued exploration and further metallurgical testwork. See Figure below:

Page 19
REASONABLE PROSPECTS FOR EVENTUAL ECONOMIC EXTRACTION OF MRE
CONCEPTUAL PITS
To ensure there were reasonable prospects for eventual economic extraction of the resource, the MRE results for both Golden Crown and Dumbarton were reported inside individual conceptual ‘open pits’ based on a Whittle optimisation study that utilised 45 degree pit wall slopes. Pit wall slopes are nominal and have not yet been validated by geotechnical drilling and geological logging.
A 20m turning circle was implemented to define the pit base dimension.
10m ‘good-bye’ slots were used in some areas where deeper mineralisation (Fresh material) would be accessible.
A gold price of AU$6,500/ounce was used.
Golden Crown Metalurgical Recovery
A metallurgical recovery of 94% was used for all material types at Golden Crown. A metallurgical recovery of 94.3% was obtained based on extensive metallurgical testwork carried out from strategically selected drillholes to ensure complete coverage of the area (ASX:M2M Announcement 6 May 2024).
Dumbarton Metalurgical Recovery
Preliminary metallurgical testwork of representative Dumbarton RC samples returned the following recoveries with average gold recoveries of ~94.8% for oxide, ~85.9% for transitional samples.
A 95% recovery for oxide mineralisation and 85% recovery for transitional and fresh mineralisation was used in the optimisation studies for the conceptual pit.
Samples submitted for fresh rock were not of high enough grade (due to limited high grade sample availability) to determine a robust recovery and further metallurgical testwork will be carried out.
Note: At Dumbarton, all fresh rock in the resource was classified as Inferred pending further metallurgical testwork.
FINAL MRE REPORTING FOR GOLDEN CROWN AND DUMBARTON
For both Golden Crown and Dumbarton only Mineralisation in their conceptual pits was reported.
Page 20
RECOMMENDED FUTURE DRILLING
Following the review by Dr. S. Carras, the following nominal further RC drilling programs have been recommended at Golden Crown and Dumbarton:
| Deposit | Recommended RC | Metres of Drilling |
|---|---|---|
| Golden Crown | Infill | 2,000 -2,500 |
| Golden Crown | Extensional | 2,000 - 3,000 |
| Dumbarton | Deeper | 1,500 - 2,000 |
GOLDEN CROWN
Infill Drilling
As a result of improved geological understanding of the structures responsible for high grade gold mineralisation at Golden Crown, a program of infill drilling focusing on shallow quartz veins which would carry coarse gold is recommended. This drilling would be to a maximum depth of approximately 35m and would enable a detailed interpretation of the coarse gold structures to be carried out for early mining and generating cashflow.
Extensional Drilling
Extensional drilling is recommended to extend the structures both laterally and at depth at Golden Crown, aimed at increasing the resource.
DUMBARTON
Approximately 64% of the resource drilling at Dumbarton is drilled into an oxide depletion zone. Deeper drilling is recommended to focus on fresh rock.
STATUS OF RECOMMENDED DRILLING
All environmental permitting is current and drillhole planning is underway for both Golden Crown and Dumbarton.
EVALUATION OF PICNIC SOUTH AND SUNDAY UNDERGROUND
The current drilling at Picnic South and Sunday Underground is being reviewed by Dr. S. Carras to establish recommendations for future work.

Note:
Easting and Northing coordinates are given in UTM MGA94 Z51 RAB drillholes in the database have been used minimally in the resource to aid in the interpretation. In general, the use of RAB drilling was not material, as specified by JORC 2012.
A small number of RAB drill holes were initially assigned as RC holes, subsequent work has resulted in a re-allocation of this minimal number of holes. This is not a material issue.

Section 1 – Sample Techniques and Data (Criteria listed in the preceding section also apply to this section.)
Criteria Commentary Reverse Circulation (RC) drill samples from the drilling campaign were collected by M2M over 1m downhole intervals from beneath a cyclone attached to the rig. Typically, 2-3kg sub-samples were obtained via a stationary cone splitter attached to the underside of the cyclone. Subsamples were collected in pre-numbered calico bags for submission to the analytical laboratory. For the sampling a mixed sampling approach was adopted for the analysis, wherein 1-metre subsamples were selected based on logging criteria. Following this selection process, the remaining portions of the drillhole were composite samples, usually 4 metres. Samples were collected from the respective bulk green plastic bags using a spear, ensuring an even representation of the entire composition. Where the weight of samples was higher in the range, systematic riffle splitting was carried out to bring the sample weight below 3kg. Previous operators of the Golden Crown Prospect conducted drilling Sampling techniques using Rotary Air Blast (RAB), Aircore (AC), and Reverse Circulation (RC) methods. These drill programs were completed at various times and on differing hole and line spacings. Sampling practices are assumed to have followed conventional industry standards—such as spear sampling for RAB and riffle splitting for RC.
All historical RAB and AC drilling data have been retained for geological context only and excluded from the Mineral Resource evaluation due to insufficient documentation of sampling procedures,QA/QC protocols, and assay methodologies. Only selected historical RC drilling—where results have been partially verified by M2M drilling—has been included in the resource estimation. (In one case only, has a low grade RAB run of samples been used in the resource estimate).
The sampling techniques and methodologies used are deemed appropriate and industry standard for this style of exploration.
M2M RC drilling was carried out using conventional, industry standard methodologies utilising a face-sampling hammer with bit shrouds. Drill bit diametres were typically 140-145mm. RC drilling was conducted by iDrillings truck-mounted Hydco 350RC 8x8 Atcross drill rig with a Drilling techniques 600/700psi 1800cfrm air compressor with auxiliary and booster air compressors (when required). All recovered samples were dry and there were no wet samples.

Criteria Commentary
The downhole survey was conducted using a True North-seeking gyro
Drilling techniques instrument (AXIS Champ Gyro), with readings taken at 10m intervals
(cont) throughout the depth of each drillhole, ensuring high accuracy azimuth
and dip measurements referenced to True North.
M2M sample collection utilised a stationary splitter attached to the
underside of the rig’s cyclone. A 2-3kg sub-sample was collected in calico
bags for submission to the assay laboratory. The remaining sample is
collected in plastic bags and stored on site for future reference. The cyclone
and cone splitter were flushed with compressed air at the end of each
6m drill rod. This process was maintained throughout the program.
Recovery percentages were recorded and are considered to be good.
Remaining part of the drillhole was covered by compositing, usually 4
Drill sample recovery metres. Samples were composited from the respective green bags using
a spear, ensuring a comprehensive representation of the entire
composition. Collected samples are deemed reliable and representative
of drilled material. No material discrepancy, that would impede a mineral
resource estimate, exists between collected RC primary and sub-samples.
No indication of sample bias is evident, nor has it been established. No
relationship has been observed to exist between sample recovery and
grade
Measures taken by other previous operators are unknown.
All drill holes are geologically logged in their entirety at 1m intervals to
the end of the hole. Drill hole data is either digitally or physically captured.
Validated and standardisation are required prior to being uploaded to
the Mt Malcolm data base. The level of logging detail is considered
appropriate for exploration and is appropriate to support mineral resource
Logging
estimation, mining studies, and metallurgical studies. M2M's qualitative
logging includes classification and description of lithology, weathering,
oxidation, colour, texture and grain size. Quantitative logging includes
identification and percentages of mineralogy, sulphides, mineralisation
and veining.
M2M samples were collected at 1m down-hole intervals. Typically, a 2-3kg
sub-sample split was obtained via a stationary cone splitter attached to
the underside of the cyclone. Sampling methodologies are considered
Sub-sampling
industry standard. Sub-samples were collected at the end of each day
techniques and
and transported to a secure location; the remaining residue (stored in
sample preparation
plastic bags) are retained at a “bag farm” on site for future reference.
Samples were kept dry by the use of auxiliary and booster compressors;
no wet samples were encountered.

Criteria Commentary
Field duplicates, blanks and Certified Reference Material (“CRM”) were
periodically inserted into the M2M sample batches at a ratio of 1:25 and
1;26 and 1:28 respectively. Sub sampling and sample preparation
techniques are acceptable; results indicate reasonable and acceptable
analytical repeatability. The QA/QC procedures implemented during the
Sub-sampling
drill program is appropriate for this style of mineralisation and industry
techniques and
sample preparation standard practice. Where the weight of samples were higher in the range
systematic riffle splitting was carried out to bring the sample weight below
3kg. Sample size and collection methodologies are considered appropriate
for this style of gold mineralisation and as an industry accepted method
for evaluation of gold deposits in the Eastern Goldfields of Western
Australia.
Analysis of M2M drilling campaign samples was conducted by Intertek
Perth and SGS, Kalgoorlie and. Samples were dried, crushed and totally
pulverised (75um). Samples were assayed for gold only using classical
Fire Assay technique with AES/ICP-OES finish on a 50 g subsample
(0.01ppm Au detection limit). Field duplicates and Certified Reference
Quality of assay data
and laboratory tests Material, standards and blanks are regularly inserted into the sample
batch. The laboratory also includes standards and blanks as part of their
internal QA/QC control. Repeatability and standard results are within
acceptable limits.

It is considered that minimal sample bias has been introduced by sample
orientation. No orientation sampling bias has been identified in the data
thus far. Drilling and sampling programs are conducted generally
orthogonal to the strike of the mineralisation, to obtain unbiased drill
sample data. The grade control drillholes were drilled vertically. It is
possible that some holes may have intersected some quartz veins at a
very high angle. This will be taken into consideration when determining
the high-grade cut to be applied.

Criteria Commentary The Golden Crown tenement (M37/475) is located within the Shire of Leonora in the Mt Margaret Mineral Field in the centre of the North Eastern Goldfields of Western Australia. The tenement is in good standing. M37/475 is held by Mt Malcolm Gold Holdings Pty Ltd, a wholly owned subsidiary of Mt Malcolm Mines NL. The tenements are managed and explored by Mt Malcolm Mines NL. The Golden Crown tenement (M37/475) is intersected by the Aboriginal Cultural Heritage (ACH) Register site Mt Malcolm (ID 1738). Although the registered ACH area overlaps the tenement boundary, it lies approximately Mineral tenement and 40 m east from the known mineralised zones. M2M is currently in active land tenure status consultation with the relevant Traditional Owner representative body. Only 45 ounces of the stated MRE are impacted by the allowance made for the Heritage boundary. These ounces have not been removed from the MRE. The details of all Company tenements are disclosed in Annexure B “Solicitor’s report on tenements” which was released by the company in its IPO Prospectus dated 2nd August 2021 “Mt Malcolm Mines NL CAN 646 466 435 Prospectus” as supplemented by a supplementary Prospectus dated 19th August 2021 (Prospectus).
All gold production is subject to a Western Australian government royalty of 2.5%. There is also a vendor royalty of 2% gross.
The Golden Crown tenement has been explored and drilled by a number of exploration and mining companies over numerous years dating back to the late 1980s, more active gold exploration companies include, Chevron, North Limited, Jubilee Gold Mines and Melita Mining NL. All have contributed to various exploration programs utilising a wide variety of standard exploration techniques.
Exploration done by other parties Exploration activities by these companies covered all aspects of mineral exploration with a particular focus on gold. On ground activities included geophysics, geochemistry, geological mapping, drill programs (RAB, Aircore, RC), sampling, structural interpretation and geological assessments.

Estimation and modelling techniques
-
�� Bottom of Oxidation (BOCO), Base of Upper Transition (UTZ) and Top of Fresh Rock (TOFR) were all based on geological logging
-
CMPL carried out a review of the weathering surfaces.
-
Based on geology and using intersection selection, 2 sets of structures were interpreted:
-
�� Subvertical mineralised shapes wireframed at a 2 g/t Au nominal cut-off grade, striking northwest and using quartz as a guide to the interpretation of the structure.
-
�� Flat dipping structures (> 0.5 g/t Au) to the northeast.
-
These mineralised shapes could contain values less than the cut-off grade within the wireframes. The parameters used for intersection selection were 2m down hole (minimum length). The intersections could include 1m of internal dilution and all intersections included 0.5m of edge dilution. This edge dilution was added to allow for the non-visible edge definition which would be experienced in the mining process.

Section 1 - Sample Techniques and Data (Criteria in this section apply to all succeeding sections.)
Criteria Commentary Samples were collected directly from the RC rig-mounted cyclone every metre on prenumbered calicos. The sample weights after cone splitting were checked for consistency; it ranged from 2- 3kg in most of the cases. A mixed sample selection strategy was employed based on geological logging. Where the geologist identified zones with higher mineralization potential or geological complexity, single metre samples were analysed. In less prospective or more geologically uniform zones, 4-metre composite samples were prepared by collecting proportional material from four consecutive 1-metre sample plastic bags (20kg) using a spear, ensuring Sampling techniques representative sampling. The remaining drill samples were kept in 20kg plastic green bags arranged in rows of 10- 20.
The vast majority of the samples were collected dry although occasional moist samples were encountered, usually close to the end of the hole associated with high water flows and slow drilling rates.
The sampling techniques and methodologies used in this program are deemed appropriate and within industry standards for this style of gold exploration.
Drilling techniques are conventional, industry standard methodologies utilising a face sampling hammer with bit shrouds. RC drill bit sizes were typically 140-145 mm. RC drilling was conducted by iDrillings (Rig 18) truck mounted Hydco 8x8 Actross drill rig with a 350psi / 1250cfm IR on board air compressor with auxiliary and booster air compressors 900psi / 1800 cfm (used when required). The drill string comprised 6m rods with a standard 5.5 inch face sampling RC bit.
Drilling technique Drilling used downhole face sampling RC hammers. The majority of metres were drilled dry, there were a few moist samples however the vast majority of returned drill spoil was kept dry. All drillholes at Dumbarton were downhole surveyed using the Comet Gyro, a reference gyroscope manufactured by Precision Mining and Drilling (PMD). The initial reading for the gyroscope was determined through Directa rig aligner which has ±0.21° heading accuracy and 0.1 degrees roll and dip accuracy.
The RC sample recoveries for each metre were visually assessed and estimated to be typically within industry acceptable standards. Where Drill sample recovery recoveries were lower than expected, generally where water was encountered, these were noted in drill logs. Moisture content was recorded in drill logs.
Page 65
Section 1 – Sample Techniques and Data
(Criteria listed in the preceding section also apply to this section.)
Criteria Commentary Collected samples are considered reliable and representative of drilled material. No material discrepancy, that would impede a mineral resource estimate, exists between collected RC primary and split sub-samples. No Drill sample recovery indication of sample bias is evident nor has it been established. No relationship has been observed to exist between sample recovery and grade. All drill holes are geologically logged in their entirety at 1m intervals to the end of the hole. All drill hole data is digitally captured. Validation and standardisation are required prior to being uploaded to the Mt Malcolm Logging database. The level of logging is detailed and considered appropriate for this type of exploration and to support appropriate mineral resource estimation, mining studies and metallurgical studies. Samples are collected and bagged at 1m intervals. Typically a 2-3kg split sub sample from beneath the cyclone via a stationary horizontal cone splitter is collected. Around 50 to 60% of these single metre samples were analysed. Sampling methodologies are consistent with the industry standard. Samples were collected for analysis at less important zones as 4m scooped composites (or 1m cone split samples off the cyclone). When anomalous, zones originally sampled at 4m composite intervals were resampled using the original cone split 1m sample. Sub samples were collected and taken to a secure location in Leonora, the remaining bulk residues are retained in green plastic bags on site at the Sub-sampling drill pad. Samples were kept dry by the use of auxiliary and booster techniques and compressors as required; a small number of moist samples were sample preparation encountered due to high water flows and slow drilling at the end of the drill holes. Field duplicates, blanks and certified standard reference material was periodically inserted into the sample batches (approximately 1 in 20). The comparison revealed no significant differences between original and duplicate results, excluding only a few spot values that are considered acceptable due to coarse type of gold mineralisation. All results consistently fell within acceptable ranges, confirming the reliability and accuracy of the analytical process.

Criteria Commentary The drill hole and sampling spacing is requirement specific; but in summary the average distance between drillholes at Dumbarton is 20 m. The drilling patterns employed in the past were dependent on previous drilling and/or geological interpretation and targeting depending on the nature and style of the mineralisation being tested. The sample spacing is considered close enough to identify any significant zones of gold mineralisation. The drill program is designed to follow up positive historical results, historical Data spacing and underground workings and remains an ongoing exploration exercise. The distribution drill program was designed to identify areas of geological interest and to confirm existing known mineralisation along the line of lode at the Dumbarton prospect. Drill spacing and the drill technique is sufficient to establish the degree of geological and grade continuity appropriate for any mineral resources and ore reserve estimation procedures and classifications applied. However, the mineralised systems remain open and additional infill or deeper drilling would be required to close off and confirm the full extent of identified mineralisation, particularly at depth. The RC drillholes were generally collared at -60 degrees dip with azimuth grid North-West (330-340 degrees) at Dumbarton. This appears to have achieved unbiased sampling based on the known structures. Regionally the sheared Mt Malcolm greenstone sequence displays an NNE to NE lithological orientation with steeply dipping stratigraphy. Stratigraphy is disrupted by the development of NW, NNW, NS, EW and NE trending faulted Orientation of data in shear systems which display a variety of fold styles ranging from open to relation to geological isoclinal, in some cases the greenstone sequence has been overturned. structure The chance of sample bias introduced by sample orientation is considered minimal. No orientation sampling bias has been identified in the data thus far. Drilling and sampling programs are conducted to obtain unbiased locations of drill sample data, generally hole orientation is orthogonal to the strike of the mineralisation. The regional geological structure is considered to be complex. Samples to be assayed are collected during the program. Once samples are collected from the field they are securely stored in a locked yard at Leonora and then transported to the analytical laboratory in Kalgoorlie Sample security by the Company Personnel. Once received by the laboratory (SGS) samples are checked against the sample submission sheet, sorted and prepared for analysis.

The details of all the Company tenements are disclosed in Annexure B “Solicitor’s report on tenements” which was released by the company in Mineral tenement and its IPO Prospectus dated 2nd August 2021 “Mt Malcolm Mines NL CAN land tenure status 646 466 435 Prospectus” as supplemented by a supplementary Prospectus dated 19th August 2021 (Prospectus). All gold production is subject to a Western Australian government royalty of 2.5% and a vendor royalty of 2% gross. There is a heritage site on the western part of the tenement but mineralisation is relatively distant (150m) from the heritage boundary and no other historical sites or environment protected areas on the tenement.
The Dumbarton tenement has been explored and drilled by a few exploration and mining companies over numerous years dating back to the late 1990s, more active gold exploration companies include: North Limited, Nova Resources and more recently Torian Resources. All have contributed to various exploration programs utilising a wide variety of standard exploration techniques. Exploration activities by these companies covered most aspects of mineral exploration with a particular focus on gold. On ground activities include helimag geophysical surveys, geochemical soil surveys, geological mapping, drill programs (RAB, Aircore Exploration done by and RC), sampling, structural interpretation, resource evaluations and other parties geological assessments. Historical reporting and descriptions of laboratory sample preparation, assay procedures and quality control protocols for the samples from the various drilling programs are variable in their descriptions and completeness. The drilling database has been assembled, interrogated, ground checked and scrutinised to a satisfactory level however, in some cases, the data is historical and predates JORC 2012 compliance.

It has not been possible to fully verify the reliability and accuracy of some portions of the data but it appears that no serious problems have occurred. Historical exploration techniques and reported mineralisation was conducted to an acceptable level and to the standards of the day. Historical grade data has been used in the mineral resource estimate, wherever it has been substantiated by recent RC drilling, both in length of intersection and grade. (Only 2 historical intersections were used.) The Project area is located 20km ESE of Leonora in the North-eastern Goldfields of W.A. The holding covers a sequence of carbonate altered mafic basalt/dolerite and possible volcanoclastic/sedimentary sequences of the Malcolm Greenstone Belt positioned within the greenstones of the Kurnalpi Terrain. Local lithologies are characterized by linear trending steeply dipping structures, quartz veining and highly sheared stratigraphy. The area is regarded as structurally complex with both EW, NE and NS shear traces; however at this stage of exploration its uncertain how the interference of these shear sets has influenced lithological patterns or mineralisation trends at Dumbarton. Geological evidence suggests that prominent east-west and northeast trending faulting and shear zones truncate the area. Rock outcrop is non-existent and the project area is covered by Recent sediments and lacustrine clays related to the nearby Lake Raeside, the area is highly weathered. Structurally the area is intensely sheared and potentially folded. Regionally gold mineralisation is associated with basalt on or near lithological contacts hosted by NW, NNW and EW trending shear zones often associated with quartz veining and dilatational jogs. Identified mineralisation occurs at depth, associated with quartz veining and carbonate/ sericite alteration in sheared and foliated basalt ± minor sulphides. There are two identified old workings evident at the Dumbarton prospect. |

No averaging of the raw assay data was applied. Raw data was used to
determine the location, width of gold intersections and anomalous gold

the relevance of the plotted intersections with respect to the sampled

In general, the drill hole orientation seems to be at an optimum angle to
the strike of the local greenstone sequence (east-west) and the identified

Further work at Dumbarton will include extensional and infill RC and
diamond core drilling to expand the mineralised footprint, improve
geological and structural interpretation, and upgrade resource confidence.
Further work Additional drilling will also support geotechnical data collection for future
mine design studies. Follow-up metallurgical testwork across all weathering
domains is planned to confirm and refine recovery characteristics and

Gold mineralisation at Dumbarton occurs along approximately 900m of
strike within a regional shear zone, where mineralised quartz veins are
hosted in carbonated basalt and intrusive dolerite. The lodes comprise
Geological
quartz–carbonate veins containing disseminated pyrite and arsenopyrite.
Interpretation
Mineralisation is consistently associated with quartz veining developed
within strongly sheared, foliated and carbonate-altered basalt, typically
located immediately adjacent to dolerite contacts
