In line with its strategic plan, Element 25 Limited (E25 or Company) (ASX: E25; OTCQX: ELMTF) is accelerating activities for the planned expansion of its Butcherbird Manganese Project in WA (Butcherbird or Project), as outlined in the Feasibility Study (FS) released in January 20241. Key areas of focus include process optimisation, Front-End Engineering and Design (FEED) activities, project finance and permitting. The Company is pleased to provide the following update.
The FS published in January 2024 outlined a compelling opportunity to expand production at the Butcherbird Mine to take advantage of the large resource base and increase commercial returns by increasing production to a nominal 1.1 Mt per annum of manganese concentrate at lower unit costs. The FS estimates a modest capital cost of $49.8M.
Element 25 Managing Director Justin Brown said: “The Butcherbird Project hosts a world-class manganese deposit with more than 260Mt in resources, which will underpin the mine as a long-life producing asset2. The decision to progress with the Stage 2 expansion project comes at a time when manganese ore prices are showing strong gains after a period of depressed pricing during 20233. The decline in prices came to a halt when the extent of the damage at South 32 Limited (S32) Groote Eylandt Manganese Mine became clear with S32 recently forecasting a disruption in production until 20254. Prices in recent weeks have rebounded strongly with current pricing for 44% high-grade material quoted at U$6.93/dmtu cif Tianjin, approximately 60% higher than the quoted pricing in early April.5”
INNOVATION AT BUTCHERBIRD
There have been important advancements, particularly in the FEED phase of the Butcherbird expansion, where the Company has optimised the plant's delivery while minimising design, cost, delivery risk, processing risks and improving energy efficiency and emission profiles. This update outlines the progress in engineering design and project management, processing plant enhancements, procurement, project scheduling, environmental initiatives, technological advancements, and the Company’s commitment to technical excellence, indigenous engagement, as well as social and environmental responsibility and sustainability.
Engineering Design and Project Management
E25 has engaged local specialist engineering firm ProjX to manage the engineering design phase and serve as owner’s engineer throughout project execution. ProjX will assist with engineering, procurement and construction management activities to ensure a streamlined and well-managed project implementation plan.
Operational Improvements
The project team has made strategic improvements to the initial plant design, enhancing operational efficiency and maximising productivity. Integrating a second-stage crushing system will process larger materials directly into the primary circuit. The feed bin and apron feeder have been upsized to optimise truck cycling times and minimise feed disruptions, which has the potential to increase plant utilisation and reduce bottlenecks. The secondary crushing stage has been optimised to handle specific material sizes, ensuring a seamless process flow and eliminating the need for additional screening and material re-handling, a key focus of the design methodology.
Mining equipment sizing optimisation modelling has confirmed equipment selection to minimise unit mining costs, rehandling and ensure continuous plant feed availability. Further studies will investigate the potential to introduce electrified mining equipment and minesite light vehicles to reduce carbon emissions.
Process controls are being designed to ensure that each principal processing stage can operate as close to maximum performance as possible whilst allowing for in-process surge points and redundancy to allow for scheduled maintenance without interrupting production. Automation is being implemented at each stage to optimise equipment set points and performance.
Water consumption reduction through the potential introduction of a thickener and intelligent recycling will reduce the impact on the local water resources while reducing bore field operational costs.
Inline analysers will enable dynamic feedback to process control systems based on desired product specifications and allow for the optimisation of product blends and sales pricing based on customer requirements.
Crushing and Screening Circuit
Through extensive review, E25 has identified significant improvements to the crushing circuit at Butcherbird. These enhancements are designed to streamline operations, reduce the frequency of plant stoppages, and optimise material handling efficiencies. Key consideration was given to the clay-rich nature of the ROM feed, and several design modifications have been made to the flowsheet to eliminate the impact of these materials. Consideration has also been given to minimising double handling of material, with direct truck dump feed as the principal feed method into a feed hopper.

Infill Drilling Completed at Butcherbird Targeting Reserve Extension to Support Expansion
Current reserves are based around mineral resources within granted mining lease M52/1074, of which less than half has been drilled to a sufficient density to meet the requirements for measured and indicated classifications. The balance is classified as inferred. The additional drilling will provide infill data to better define and potentially convert these areas to indicated or measured categories to support the re-estimation of mine reserves. The increase in the “reserve tail” will support project financing activities with NAIF and other potential financiers who are currently undertaking project expansion due diligence2.
HIGHLIGHTS
- 207 percussion drill holes have been completed for 6,202m targeting infill of existing inferred resources.
- All samples have been dispatched to Bureau Veritas for assay with results pending.

The Project hosts a global resource of over 260Mt of manganese ore3 however the current reserves are limited to the areas which have been drilled out to measured and indicated classifications which are required as the basis for a statement of reserves. The current drilling programme was designed to infill existing inferred resources to a sufficient data density, based on variographic analysis, to convert the inferred resources within granted mining lease M52/1074 to indicated and/or measured.
The additional drilling information, combined with historical data, will be used to recalculate the resource base to support a recalculation of the proved and probable reserves to support project financing activities for the Butcherbird Expansion Project by increasing the “reserve tail”. Samples have been submitted for assay with results pending.

Element 25 Managing Director Justin Brown said:
“This drilling programme will allow the global resource at Butcherbird to be recalculated with a higher degree of certainty which is expected to result in a signification conversion of inferred resources to measured and indicated classifications to increase the reserve tail in support of the planned ramp up to 1.1Mt production rates.”

E25 Investigates Butcherbird Restart Options Amid Record High Manganese Ore Prices
HIGHLIGHTS
- Manganese ore prices rise to four-year highs to U$8.30/dmtu for 44% cif Tianjin, China1.
- E25 operations team and Board investigating opportunities to process ROM and low-grade stockpiles at Butcherbird.
- If operationally feasible, ore production at current prices presents an opportunity to generate short-term cash flow.
GEMCO’s Groote Eylandt Mine typically produces more than 6M tonnes of high-grade manganese ore a year, and damage to the mine’s haul road and ship loading facilities from Tropical Cyclone Megan in March 2024 has resulted in a forecast supply disruption of up to twelve months. GEMCO is currently targeting a production restart in Q3 2025.2
Figure 1: Manganese ore index – Yuan/dmtu Tianjin Port1. Butcherbird Expansion Feasibility Study parameters also shown3.
The loss of GEMCO supply coupled with political instability in South Africa has resulted in a significant and rapid increase in manganese ore prices due to increased competition for available supply. This presents an opportunity to potentially sell stockpiles that are of a lower grade, preventing their previous sale at lower prices but which may be profitable to ship now.
Additionally, ROM stockpiles that have been mined but not yet processed are available at site. The cost structure of a restart is not currently defined, however E25’s Board recognises the potential opportunity of selling existing product stockpiles and/or recommencing the processing of ROM stockpiles at Butcherbird to produce material for sale at current elevated prices. If viable, these activities will occur in parallel with and will not impact the expansion plans for the Butcherbird Project. E25 suspended Butcherbird production in early 2024 during a period of depressed ore prices while readying for an upgrade of facilities to achieve a nominal 1.1Mpta manganese concentrate production, as outlined in a Feasibility Study completed on January 20243.
The expansion of Butcherbird production aligns with E25’s strategy to produce high-purity manganese sulphate monohydrate (HPMSM) at a facility planned to be built in Louisiana, USA, in partnership with global automakers General Motors LLC and Stellantis NV4.
Element 25 Managing Director Justin Brown said:
“A potential restart of Butcherbird’s processing operations at these increased manganese ore prices on a de-risked basis may be an ideal opportunity to monetise existing stockpiles and generate short-term cashflow. E25 looks forward to updating the market further as these investigations are completed and we will continue to monitor ore markets in the meantime to optimise any potential opportunities that may arise.”
