Acquisition of Wyemandoo Project Expands COY’s Australian Portfolio

Coppermoly Limited (ASX:COY) (the Company ) is pleased to announce that the Company has completed the acquisition of a 100% interest in the Wyemandoo Project in Western Australia via the acquisition of tenements E57/1017, E58/555 and E58/571 from Aldoro Resources Ltd (ASX:ARN) ( Aldoro ), and 100% of the fully paid ordinary shares in the capital of Altilium Metals Pty Ltd, being the holder of the tenement E59/2431 ( Acquisition ).

Coppermoly Limited (COY) has expanded its Australian portfolio by acquiring 4 new Western Australian (WA) tenements, complementing its 5 existing Queensland (QLD) tenements, bringing the total project footprint to 1,805 square kilometres. This strategic acquisition enhances COY’s exposure to prospective mineral exploration in high-yield Australian jurisdictions.

Coppermoly Managing Director Dickson Leah commented:

“ We are very pleased to announce the acquisition of the Wyemandoo project from Aldoro Resources. This transaction represents a key step in Coppermoly’s strategy to secure highquality, advanced critical mineral projects in Western Australia.

The Wyemandoo tenements, known for Lithium-Rubidium and significant tungsten mineralisation, directly complement our existing exploration efforts. These assets present immediate, targeted drilling opportunities, including 1,500m of planned RC holes, following encouraging surface rock chip results.

This acquisition strengthens our position in a proven, high-potential region in Western Australia and Queensland with combined exploration area of 1,805 km[2] and adds value on the combined assets, and I look forward to advancing exploration activities at Wyemandoo and delivering value to our shareholders."

Wyenamdoo Project and Commodity Overview

The Wyemandoo Project, 80km southeast of Mount Magnet, covers 259.25km[2] of contiguous licences E59/2431, E57/1017, E58/555 and E58/571 on the southeastern margin of the Windimurra Igneous Complex (WIC).

The project is a high-grade, multi-commodity, critical minerals opportunity in Western Australia. It offers significant leverage to high-demand battery and tech metals, specifically

high-grade Rubidium (Rb), Tantalum (Ta), Titanium (Ti) and Tungsten (W) within an extensive 10km+ pegmatite fairway.

JORC Results

Significant tungsten (W) potential on rock chips within 4.5km long corridor

• W range on rock chips 0.01% - 13.1% W

• Prices skyrocketed from roughly US$300/mtu in early 2025 to over US$2,650/mtu by March 2026, an increase by 783%

• Demand is surging, specifically for high-performance tungsten alloys in defence, aerospace, and semiconductor manufacturing, which cannot be easily replaced by alternatives

• The market is projected to reach approximately US$7.6 billion to US$16 billion in 2026

• Global stockpiles have plummeted to multi-year lows, 90% reduction since 2024,

Exceptional Rubidium (Rb) in rock chips and drill holes

• Rock Chips : Results of >0.01% Rb up to >1.82% Rb

• Drill Holes: Encouraging intercepts show widths of over 2m–20m at grades exceeding 0.1%–0.5% Rb ₂ O

• Technical rubidium grade ranges from USD $3.000 – $5,000/kg while high purity exceeds USD $5,000 – $7,000/kg

• A key component in rubidium atomic clocks , which are used in telecommunications and global positioning systems (GPS) for precise timing. Elon Musk, the USD 800 Billion Dollar Man (Forbes) has applied to launch 1 million satellites into Earth’s Orbit to power artificial Intelligence (AL). ( bbc.com/news/articles/cyv5l24mrjmo )

• High precision technology used mostly by defence and in demand when engaged in war

Elevated Titanium (Ti) in rock chips and drill holes

• Pervasively high-grade mineralisation in drill holes from surface to end of hole. Open in all directions. (will be reported in upcoming Investor presentation)

• Encouraging rock chip grades ranges from 0.01% - 1.66% Ti

• • Titanium market size has reached to $28.2 billion in 2025

• Expected to grow to $37.79 billion in 2030 at a compound annual growth rate (CAGR) of 6.1%

• Fuelled by Aerospace Industry's Increasing Demand

Highly encouraging Tantalum (Ta) mineralisation in rock chips

• Ta ranging from 0.02ppm - 4,800ppm, having significant potential for further investigation

• Tantalum prices have surged, with concentrate prices rising to around USD $190193/kg (https://pubs.usgs.gov/periodicals/mcs2024/mcs2024-tantalum)

• Demand surge driven by electronics, steel alloy, aerospace

Wyenamdoo Exploration Motto - “Prioritize big systems over isolated highgrade hits”

• RC drilling for Tungsten is expected in quarter 3

• Followed by grid geochemical sampling

• Geophysical survey (gravity – identify denser metals such as W, Ta, Ti and Rb in order of high to low density)
