Highlights

• Resolution Minerals has received final LiDAR data for the Drake East Project.
• The report has identified 791 mine workings in the project area, including 742 pits, 33 shafts, and 16 adits.
• The findings align with 70 historical antimony and gold prospects in the project area, as recorded in MinView data.
• Newly identified mine workings suggest unrecorded mineral occurrences.

Resolution Minerals Ltd (ASX:RML) has received the final LiDAR data reprocessing and interpretation report for its Drake East Antimony-Gold Project in New South Wales.  

The high-quality LiDAR survey identified 791 mine workings across the project area, comprising:

• 742 pits
• 33 shafts
• 16 adits

Most of these mine workings align closely with 70 antimony and gold prospects historically recorded in the Drake East project, as listed in the NSW Geological Survey MinView online data portal.

Newly interpreted mine workings were also found that do not correspond to the MinView prospects, suggesting the presence of unrecorded mineral occurrences.

Hedley’s Reef – Gully Prospect Area

The Hedley’s Reef hosts 90 identified mine workings, comprising 75 pits, nine shafts, and six adits. The mine workings display a substantial linear control of gold-antimony mineralisation due to association with the Bucklands Reef Gold Prospect and the Hedley’s Reef Antimony Prospect. This area is believed to be part of the broader antimony-gold mineralisation of the Lunatic Antimony Field.

Hansen Hills – Hidden Treasure Area

This area hosts 112 mine workings, including 109 pits, one shaft, and two adits. Just like Hedley’s Reef, the Hansen Hills mine workings exhibit a NW-SE and NS orientation, reinforcing the presence of vein-hosted gold and antimony mineralisation. Given the similarities in mineralisation style, geology, and vein orientation, RML considers Hansen Hills to be an extension of the broader Lunatic Antimony Field mineralisation.

Reliance Mine – Rileys Alluvials Area

Positioned centrally within the project, this area comprises multiple gold and antimony vein prospects along with an extensive placer gold field. The Reliance Gold Mine area hosts 75 mine workings, including 65 pits, 8 shafts, 2 adits, and 17 trenches. The widespread occurrence of placer gold workings suggests additional undiscovered vein-hosted gold mineralisation. The gold distribution follows erosion patterns in the Carboniferous-aged Emu Creek Formation, further supporting the potential for more mineralised veins in the area.

Ottis Mine – Lanikai Alluvial Area

Similar to the Reliance Mine – Rileys Alluvials Area, the Ottis Mine – Lanikai Alluvial Area contains gold and antimony-gold veins alongside extensive placer gold deposits. The number of mine workings are too numerous to count due to the intense historical mining activity. Three notable sub-areas within this region include:

• Lanikai West Gully & Lanikai East Gully Alluvials (43,000 m²)
• Clarence River Alluvials (71,500 m²)
• The Yellow Creek Alluvials (21,000 m²)

Pine Gully – Mosquito Creek Antimony Area

Located in the northern part of the project, this area contains 19 identified mine workings (17 pits and 2 adits). The Mosquito Creek Antimony Prospect, one of the most significant sites, is described as a vein "reef" with a strike length of 1,000m. However, the company needs to further confirm this estimate. The NW-SE orientation of the mine workings aligns with other antimony-gold prospects in the project.

Summary of five areas

Next Steps & Exploration Plans

RML aims to focus on ground-truthing significant mine workings to assess economic potential for gold, antimony, and copper. Planned activities include:

• Desk-top reviews of nearly 800 mine workings and 70 MinView mineral prospects
• A desk-top review to assess the placer gold potential
• Field mapping and geochemical rock chip sampling for high-priority targets
