791 ANTIMONY, GOLD AND COPPER MINERALISATION MINE WORKINGS IDENTIFIED AT DRAKE EAST IN FINAL LIDAR INTERPRETATION

HIGHLIGHTS

• RML has received a final report for a High-quality Light Detection and Ranging (“ LiDAR ”) interpretation conducted at the Company’s Drake East Antimony-Gold Project. A total of 791 mine workings, including 742 pits, 33 shafts and 16 adits, have been interpreted across the Drake East Project area.

• The vast majority of these mine workings correspond to the seventy historical [mostly] gold and antimony prospects recorded at Drake East. CAUTIONARY NOTE: The gold and antimony prospects are historical and are not 2012 JORC Code compliant. The Competent Person has not done sufficient work to classify these occurrences as mineral resources in accordance with the 2012 JORC Code. There are no guarantees that further tests would elevate these occurrences to 2012 JORC Code compliancy.

• The antimony / antimony-gold mineralisation is classified as antimony-quartz, antimony-goldquartz, and antimony-gold-tungsten-quartz vein-type.

• The Hedley’s Antimony and Hensen Hills Antimony Prospect areas are believed part of a large NE-SW orientated antimony-gold mineral field that also includes the Lunatic Antimony Field which occurs on Legacy Minerals’ Drake Project (ASX: LGM).

• The LGM Lunatic Antimony Field hosts vein-hosted mineralisation with peak grades of 30% antimony and 85g/t gold. Refer to LGM Announcement dated 26 February 2025.

• As previously announced by RML (ASX announcement 10 March and 26 March 2025) Drake East hosts high-grade antimony, high-grade gold, and high-grade silver mineralisation, including peak values of 5.72% Sb, 60.9 g/t Au and 214 g/t Ag from sampling of various historical workings.

• LiDAR interpretations have also identified a concentration of placer gold mine workings covering an estimated area of 135,500 square metres in the Lanikai Alluvial Prospect area.

• RML to expedite fieldwork including geological mapping and geochemical rock chip sampling.

Antimony-gold focused exploration company Resolution Minerals Ltd (“ RML ” or the “ Company ”) ( ASX: RML ) is pleased to announce that it has received the final LiDAR data reprocessing and interpretation report (“ Report ”) for its Drake East Antimony-Gold Project (“ Drake East ” of the “ Project ”), located in NSW, Australia (subject of previous ASX announcements of 10 March, 17 March, 25 March and 26 March 2025). The Report was received from LiDAR data reprocessing and interpretation specialist service provider GeoCloud Analytics (“ GeoCloud ”).

Seven hundred and ninety-one workings were identified from the LiDAR data by GeoCloud. The final report was reviewed by the principal geologist of Riviere Minerals Pty. Ltd. (“ Riviere ”), Mr Ross Brown. Mr Brown has adequate experience in geomorphology to qualify as Competent Person regarding this exploration activity. These workings by and large coincide with the 70 antimony and gold prospects known to occur within RML’s Drake East Project as recorded in the NSW Geological Survey MinView online data portal (“ MinView ”) (Table 1) (Figure 1). The antimony and gold prospects occurring at Drake East were the subject of four prior ASX announcements made by the company, dated 10 March, 17 March, 25 March and 26 March 2025.

Drake East Project Area LiDAR Results

The entire Project area hosts a total of 791 mine workings, including 742 prosecting pits, 33 shafts and 16 adits. These are spread over the 70 MinView antimony, gold, silver, copper and base metal prospects known to occur within RML’s Drake East Project (Table 1) (Figure 1).

There are also newly interpreted mine workings which do not correspond to the MinView prospects (Figure 1) indicating that there are mineral occurrences present that are not recorded in MinView.

Five areas have been recognised that have high concentrations (or “clusters”) of mine workings associated with the MinView prospects. These include:

• Hedley’s - Gully Prospect Area

• Hansen Hills - Hidden Treasure Area

• Reliance Mine - Rileys Alluvials Area

• Ottis Mine - Lanikai Alluvials Area

• Pine Gully - Mosquito Creek Antimony Area

These are discussed in further detail below.

Hedley’s - Gully Prospect Area

The Hedley’s Reef – Gully Prospect Area hosts 90 interpreted mine workings, including 75 pits, nine shafts and six adits (Figure 3). The majority of these are associated with the Hedley’s Reef Antimony Prosect and the Bucklands Reef Gold Prospect.

The configuration of the mine workings indicates a strong linear control of gold-antimony mineralisation. This is consistent with the vein-style mineralisation known at the Buckland Reef gold prosect and the Hedley’s Reef antimony prospect. There are two vein orientations: NW-SE and NS.

Located in the southwestern part of the Project area, the Hedley’s Reef – Gully Prospect mine workings cluster is approximately 4km northeast of Legacy Minerals’ (“ Legacy ”) Lunatic Antimony Field (Figure 2 RIGHT). Legacy detailed rock chip sample assay results from the Lunatic Antimony Field in an ASX announcement dated 26 February 2025.

Figure 1 of Legacy’s announcement dated 26 February 2025, with the title “30% Antimony and 85g/t gold in Rock Chips at the Drake Project” is copied RIGHT, without modification. Directly relevant to RML’s Hedley’s Reef and Gully Prospect areas, there is a clear NW-SE to NS orientation of the gold and antimony veins comprising the Lunatic Antimony Field. Cautionary Note : Please refer to the Legacy 26 February 2025 Announcement for details of their exploration results.

3 April 2025

RML believes that the antimony-gold mineralisation of Hedley’s Reef – Gully Prospect Area is part of the same, broader, antimony-gold mineralisation of the Lunatic Antimony Field (Figure 2). The style of mineralisation, host geology and the orientation of the veins are all similar.

Figure 3: LiDAR image (right) with location geological location plans (left). The LiDAR image was produced by GeoCloud. The author has added trend lines and certain captions: Yellow dashed lines highlight the orientation of the mine working; CAUTIONARY NOTE : The inserts are from areas expanded from the primary plan. The coordinates (and north arrow) of the inserts are therefore constrained by the primary plan.

Hansen Hills - Hidden Treasure Area

The Hansen Hills - Hidden Treasure Area is located centrally in the southern part of the Project area. It is 2km NE of the Hedley’s - Gully Prospect area (discussed above), and approximately 6km northeast of Legacy Minerals’ Lunatic Antimony Field.

The Hansen Hills - Hidden Treasure Area hosts 112 mine workings including 109 pits, one shaft and two adits (Figure 4).

3 April 2025

Like the Hedley’s Reef – Gully Prospect antimony prospects, the Hansen Hills - Hidden Treasure Area mine workings display a strong NW-SE and NS orientation, again, as would be expected in the case of vein-hosted Sb and Au mineralisation.

==> picture [502 x 433] intentionally omitted <==

Figure 4: LiDAR image (right) with location geological location plans (left). The LiDAR image was produced by GeoCloud. The author has added trend lines and certain captions: Yellow dashed lines highlight the orientation of the mine working. White dashed lines highlight interpreted lineation that is reflected in local drainage patterns. Drainage systems often reflect underlying linear geology (dykes, faults, joints, sheers, geological contacts) as a result of preferential erosional. CAUTIONARY NOTE : The inserts are from areas expanded from the primary plan. The coordinates (and north arrow) of the inserts are therefore constrained by the primary plan.

Like with the Hedley’s Reef – Gully Prospect Area, RML believes that the antimony-gold mineralisation of the Hansen Hills - Hidden Treasure Area, forms part of the same, broader, antimony-gold mineralisation of the Lunatic Antimony Field (Figure 2). The style of mineralisation is the same, the host geology is the same, and the orientation of the veins is the same.

Reliance Mine - Rileys Alluvials Area

The Reliance Mine - Rileys Alluvials Area is located in the central part of the project area. It comprises several gold and antimony vein prospects and an extensive field of placer gold prospects. The total number of mine workings in the area is too numerous to count (owing to the intense concentration of alluvial diggings). In the Reliance Gold Mine area alone, there is a total of 75 mine workings, including 65 pits, eight shafts, two adits and 17 trenches (Figure 4).

Like the LiDAR mine workings of the antimony-gold prospects discussed above, the same mine workings orientation occurs in the Reliance Mine - Rileys Alluvials Area. The occurrence of widespread alluvial (placer) gold prospects introduces a less linear configuration of the mine workings (Figure 5). The distribution of such placer prospects is influenced by the present-day erosion of the known gold-bearing Carboniferous-aged Emu Creek Formation. The Emu Creek Formation occurs throughout the Project area.

To clarify, the spatial control of the mine workings of placer gold prospects is not related to the occurrence of antimony-gold veins but relates to the drainage system as seen in Figure 5.

==> picture [500 x 276] intentionally omitted <==

Figure 5: LiDAR image (right) with location geological location plans (left). The LiDAR image was produced by GeoCloud. The author has added trend lines and certain captions: Yellow dashed lines highlight the orientation of the mine working. Curved orange dashed lines highlight interpreted alluvial gold drainages. CAUTIONARY NOTE : The inserts are from areas expanded from the primary plan. The coordinates (and north arrow) of the inserts are therefore constrained by the primary plan.

The distribution of the placer gold mine workings is also useful in interpreting the possible occurrence of additional vein hosted gold mineralisation. The occurrence of place gold in first and second order creeks (Figure 5) strongly indicate that the source of [placer] gold is very localised.

The widespread nature of the alluvial mine workings in the Reliance Mine - Rileys Alluvials Area therefore strongly indicates the occurrence of significantly more mineralised veins than currently known.

Ottis Mine - Lanikai Alluvial Area

The Ottis Mine – Lanikai Alluvial Area is located in the central northern part of the project area. It is very similar to the Reliance Mine - Rileys Alluvials Area in that it hosts a combination of gold and antimony-gold veins and several clusters of placer gold mine workings (Figure 6).

==> picture [480 x 405] intentionally omitted <==

Figure 6: LiDAR image (right) with location geological location plans (left). The LiDAR image was produced by GeoCloud. CAUTIONARY NOTE : The inserts are from areas expanded from the primary plan. The coordinates (and north arrow) of the inserts are therefore constrained by the primary plan.

It is not possible to calculate with certainty the total number of mine workings in the Ottis Mine – Lanikai Alluvial Area such is the intensity of the alluvial placer gold workings. Three sub-areas of the Ottis Mine – Lanikai Alluvial Area are presented in this announcement to illustrate the intense nature of past alluvial gold mining activity.

The Lanikai West Gully Alluvial and the Lanikai East Gully Alluvials (Figure 7) cover an area of 43,000 square metres. The Clarence River Alluvials (Figure 8) cover an area of 71,500 square metres. The Yellow Creek Alluvials (Figure 9) cover an area of 21,000 square metres. The three placer gold areas have a combined total area of 135,500 square metres. CAUTIONARY NOTE: The estimate of the area of mine workings is not a measure of the extent of placer gold mineralisation.

Pine Gully– Mosquito Creek Antimony Area

The Pine Gully - Mosquito Creek Antimony Area is located in the northern part of the Project. It hosts total of 19 interpreted mine workings, including 17pits, and two adits associated seven metal occurrences (Figure 10).

The Mosquito Creek Antimony Prospect is among the most significant in the Drake East Project area, described as a vein “reef” with a strike length of 1,000m and strike direction of NNE (MinView). Cautionary Note : The Competent Person has not done sufficient work to verify the MinView data. There are no guarantees that further tests would confirm that the Mosquito Creek Antimony Prospect is approximately 1,000m long.

==> picture [504 x 435] intentionally omitted <==

Figure 10: LiDAR image (right) with location geological location plans (left). The LiDAR image was produced by GeoCloud. The author has added trend lines and certain captions: Yellow dashed lines highlight the orientation of the mine working. White dashed lines highlight interpreted lineation that is reflected in local drainage patterns. A single black dashed line reflects a MinView description of a NNE 1,000m gold-antimony reef. CAUTIONARY NOTE : The insert areas (A and B) are from areas inside the primary plan, as indicated on the primary plan. The coordinates (and north arrow) of the inserts are therefore constrained by the primary plan.

3 April 2025

The linear configuration of the mine workings comprising the Pine Gully Lode North and Pine Gully Lode South, interpreted from LiDAR, indicates a NW-SE orientation which is consistent with the interpreted vein orientations in the southern part of the project at the Hedley’s - Gully Prospect Area and Hansen Hills - Hidden Treasure Area.

Next Steps and Funding

The planned next step at Drake East is to ground-truth those mine workings that are considered significant; those relating to potentially economic levels of antimony and/or gold, and/or copper.

Upcoming planned programs include (but not limited to):

• A desk-top review to prioritise the nearly 800 mine workings for fieldwork including geological mapping and geochemical rock chip sampling.

• A desk-top review of the 70 MinView mineral prospects.

• A desk-top review if the placer gold potential of the Project.

• Mapping and sampling of high priority mine workings, MinView prosects, and new targets.

The author of this announcement understands that the Company has adequate funds to complete this planned exploration activity.

RML Management Says

Executive Director, Aharon Zaetz, commented about the LiDAR results and independent review:

“ The final LiDAR interpretation now reviewed by Riviere has provided RML further insight into the antimony and gold potential of Drake East. This project clearly has very significant upside with nearly 800 mine workings, that in reality are too numerous to count. The widespread placer gold workings are in their own right a valid and exciting exploration target. That they strongly indicate a very local source of gold is equally exciting. And then there is of course the antimony and antimony-gold vein potential, which is very significant, believed part of the same mineral system that included Legacy’s adjacent Lunatic Antimony Field.”

About the Drake East Antimony-Gold-Copper Project

The Drake East Project is considered a highly prospective brownfields opportunity with past historical antimony production. The Drake East Project is immediately adjacent to the Legacy Minerals Holdings Ltd (ASX: LGM) Drake Gold-Copper Project where they are developing a large epithermal gold-copper mineralised system.

The Drake East Project hosts fifteen known antimony occurrences, including the well-documented Mosquito Creek Antimony-Gold Reef. These antimony occurrences cover a large area with a NW-SE strike length of over 15km (Figure 1 and Figure 2). The project also hosts fifty gold occurrences, including a placer gold resource at Lanikai West.

A significant antimony occurrence at Drake East is called the Mosquito Creek Antimony-Gold Reef . Antimony and gold here are associated with a vein system bearing 30 NE, 1,000 metres in length, cutting local geology (Emu Creek Formation mudstones and Jenny Lind Tonalite granites). Antimony (and gold) mineralisation appears to be closely associated with NE-SW structures that spray from the Jump Up Fault (Figure 2). Another significant antimony occurrence at Drake East is the Ball & Smiths Lode , centred in the southern half of the project area. Juxtaposed with several other antimony and gold occurrences, the Ball & Smiths Lode is an historical 1870’s mine (shafts and open pits). Assays from Sample Number G00/363 reports 5.72% Sb and 0.26g/t Au.

Note: All sample results have been referenced in previous RML ASX announcements. The author has not completed sufficient studies to be able to verify the reported grades.

The style (classification) of mineralisation is believed to be structurally controlled metahydrothermal vein AuSb-W (Ag-Te) type. In these types of deposits, antimony characteristically occurs as the sulphide ore mineral stibnite (Sb2S3 with 73% mol weight antimony).

As well developing the antimony potential of the Drake East Project, the Company will also pursue the gold (silver and copper) potential. Drake East has 50 documented historical gold occurrences, with assays at Pine Gully returning up to 60.9 g/t, and historical production at Bucklands Reef of 100 tonnes @ 32.6 g/t Au.

Note: All sample results have been referenced in previous RML ASX announcements. The author has not completed sufficient studies to be able to verify the reported grades.

Limited systematic and modern exploration at Drake East represents significant opportunity for Resolution Minerals. RML plans to initiate systematic exploration programs, including geophysical surveys, geochemical sampling, and drilling campaigns, to evaluate the mineral potential of these projects.

Appendix 1: How LiDAR Works (Taken from GeoCloud website).

Light Detection and Ranging (LiDAR) is a remote sensing technique that uses laser pulses to measure distances and directions to objects. LiDAR systems can create 3D models of the earth’s surface (see Figure 11). A laser scanner fitted to an aircraft scans along its flight path, sending pulses out at a rate up to 1000khz, with multiple target reflections per pulse. While scanning, the GPS (GNSS receiver) on the aircraft is in constant communication the GPS satellite constellation, always knowing where it is in 3D space. During flight, the subtle aircraft movements are recorded, allowing post processing to correct these deviations ensuring the laser scan lines are calibrated and corrected for maximum precision and accuracy.

The standout feature of LiDAR is its ability to see the ground through trees and heavy vegetation.

LiDAR Can Detect Old Mine Workings

Historical mine shafts can be detected using this technology, which essentially “sees through” the vegetation cover that may conceal old shafts overgrown. Given the historical mining that has taken place at Drake East, the LiDAR study is perfectly suited to helping identity areas of interest and provide a series of initial targets to focus further exploration on.
