ASX ANNOUNCEMENT 28 JULY 2022

Dense Media Separation Bulk Trial Achieves 9-30% Grade Uplift on Butcherbird Ores

  • Bulk Dense Media Separation ( DMS ) trial conducted on Butcherbird manganese ores confirms the potential for improved processing using a DMS drum circuit vs ore sorters.

  • Approximately 280 tonnes of material from the current operational areas transported to existing DMS facility for batch processing to evaluate DMS process effectiveness.

  • Programme conducted as part of option evaluation for future plant expansion.

  • Results indicate potential product grade improvement of 9-30%.

  • More consistent separation of ore and waste achieved compared to ore sorters.

  • Potential commercial benefits include a reduction in ore haulage and shipping costs and improvements in payability (achieved price/dmtu) due to higher grades.

  • Butcherbird expansion studies will review options to incorporate a DMS drum in the processing circuit in future planned upgrades to the existing facility.

Element 25 Limited ( E25 or Company ) ( ASX:E25 ) is pleased to

announce that it has completed a bulk trial, processing approximately 280 tonnes of Butcherbird manganese ores through the Dense Media Separation ( DMS ) plant located at the Bootu Creek Manganese Mine in the Northern Territory.

The Bootu Creek Mine is owned by E25’s off-take partner, OM Holdings Limited ( OMH ). The test programme was undertaken in midJune 2022.

The 280 tonne trial parcel, made up of six parcels of between 44 to 49 tonnes each, was transported to the Bootu Creek Manganese Mine via road train for processing through the existing production DMS facility.

Market Summary Board of Directors: ASX code: E25 Seamus Cornelius Chairman Shares on issue: 153M Justin Brown MD Share price: $0.565 John Ribbons NED

Element 25 Limited is developing the world class Butcherbird Manganese Project in Western Australia to produce high quality manganese concentrate and high purity manganese products for traditional and new energy markets.

The six parcels were processed through the DMS drum plant using three different media densities of 2.7, 2.9 and 3.1 g/cm[3] , to provide data on the optimal processing design parameters for Butcherbird material.

The trial results clearly indicate that the use of a DMS drum can meaningfully improve manganese product grades by improving the elimination of waste and gangue materials from the product stream.

Manganese pricing is positively impacted by higher grades and eliminating sub-grade waste material also reduces the overall haulage and shipping costs of transporting the concentrate to market, thereby reducing overall operating costs, .

Trial Programme Results

Six parcels of ore were processed. Sample A consisted of five parcels of low-grade Butcherbird post ore-sorter manganese product with the primary feed material sourced from current operational mining faces to provide material for the test programme. Sample B consisted of a single sample of post- scalper ore which had undergone primary screening for the removal of fines material, with the coarse fraction used for the test programme through the DMS circuit. This was then compared to material from the same parcel of scalped ore which was further processed at Butcherbird via the existing process plant.

==> picture [595 x 67] intentionally omitted <==

The results from the DMS processing of Sample A resulted in the removal of an additional 3.5-7.3% of waste material by weight from the run-of-mine feed that had undergone processing using the current production circuit. All cut densities yielded a similar result with a slightly better result at the highest cut density of 3.1 g/cm[3] .

The net result is an increase in the final manganese grades from 28.3% Mn to up to 30.9% Mn, equivalent to a 9.1% improvement. Importantly this demonstrates that even for material where the ore-sorters struggle to achieve the optimum product grades, the DMS process is likely to deliver a higher product grade.

Figure 3. DMS test results for Sample A

Sample B comprised sub-grade material which was treated using two different methods. The bulk of the parcel was processed through the existing plant at Butcherbird, and yielded a below specification grade of 24.4% Mn due to presence of clays and other factors which impacted the effective operation of the ore sorter and its ability to remove the waste material.

The ore sorters work using optical colour sensors which measure the Red-Green-Blue ( RGB ) colour of each feed particle. The sorters classify each particle as either ore or Figure 4. Butchebrird ore post DMS processing waste according to the algorithm that is currently being used. Consequently, it is very important that material is presented as cleanly as possible as any surficial clays or other debris can negatively impact the ore sorter effectiveness.

The DMS process relies on particle density so surface contamination should have only a minor detrimental impact. Importantly and as expected, the DMS plant was not effected by the presence of clays and other surface effects and successfully upgraded the relatively poor ore-sorter result of 24.4% Mn to an significantly improved grade of 32-33.4% Mn depending on the cut density.

As the cut density increases, the product grade increases, also as expected, however there is an associated recovery loss. The optimal density cut is still to be defined, however it is clear from these results that a relatively easily achievable medium density of 2.7 is adequate and the optimal density may be even lower, potentially reducing media costs.

2.9 32.2 88.6 39.7 11.9
3.1 33.4 72.2 59.5 31.7

Figure 5. DMS test results for Sample B

Sample B shows that the use of a DMS circuit can increase the manganese grade by an extra 7.55 to 8.92% by the removal of material which is currently part of the tonnage of waste in the Ore Sorter product. This allows manganese grades to increase from 24.4% Mn to between 32.0 and 33.4% Mn for that material, equivalent to at least a 30% improvement.

Element 25’s, Managing Director Justin Brown, said “ The DMS trial has demonstrated that there are significant potential improvements and costs savings available to Element 25 by using a DMS drum circuit as an alternative to the current ore sorting stage of the manganese processing flow sheet. A modified process including DMS should result in more consistent grades and recoveries which in turn should attract higher premiums on price and reduce operating costs. The Company is currently undertaking engineering work to include a DMS drum in a future plant reconfiguration at Butcherbird .”

About the Butcherbird Manganese Project

E25’s Butcherbird Manganese Project is a world-class manganese resource with current JORC resources of more than 263Mt of manganese ore[1] . In May 2020, the Company completed a Pre-Feasibility Study ( PFS )[2] with respect to developing the deposit to produce manganese concentrate for export to generate early cashflow with a modest capital requirement[3] . Stage 1 of the Project development plan is complete and E25 has commenced shipping ore to offtake partners.

The PFS also highlighted the Project’s potential for significant growth beyond the initial Stage 1 production volumes (the studies examined the potential for a 2X and 3X expansion to Stage 1 within 12 months of initial commissioning), and the Company plans to expedite the expansion of the Project as soon as practicable once final process optimisation work is completed and relevant approvals are in place.

In addition to the concentrate export business, the Company has completed extensive research & development and laboratory test work into the production of high purity manganese products including battery grade manganese sulphate (HPMSM) and High Purity Electrolytic Manganese Metal (HPEMM). The work has highlighted that the Butcherbird ores are highly amenable to an ambient temperature, atmospheric pressure leach process, resulting in a very efficient extraction of the manganese into solution, the key requirement for the cost effective and sustainable production of HPMSM and HPEMM.

The Project straddles the Great Northern Highway and the Goldfields Gas Pipeline, providing turnkey logistics and energy solutions. The Company plans to integrate renewable energy into the power solution over time to target a zero-carbon footprint for the Project, which is expected to also reduce energy costs. A cleaner, lower carbon flowsheet and high penetration renewable energy will place Butcherbird at the forefront of sustainable high purity manganese production.
