Australian manganese explorer and developer, Black Canyon Limited (Black Canyon or the Company) (ASX: BCA) is pleased to announce that reconnaissance mapping and rock chip sampling completed over the Wandanya Project has identified high-grade manganese mineralisation.
- Reconnaissance sampling over the Wandanya (E46/1407) tenement (BCA 100%) has delivered high-grade surface rock chip samples up to 54% manganese (Mn).
- Two samples taken 100m apart (across strike) returned 52.9% and 54.3% Mn from an outcrop that is approximately 300m long and 150m wide at the W2 prospect.
- Other samples targeting manganese across the tenement ranged between 12.2% and 33.5% Mn.
- No previous surface sampling or historic drilling has been completed over the outcropping mineralisation.
- Future exploration plans include additional mapping, sampling and gradient array IP (GAIP) to generate drill targets.
The sampling program was part of the initial assessment of the tenement to determine geological setting and mineralisation potential. The Wandanya tenement is located on the eastern boundary of the Oakover Basin and approximately 80km south of the Woodie Woodie manganese mine. Further work is planned to follow-up the results and continue mapping along strike to north.
Black Canyon’s Executive Director Brendan Cummins said:
“The high-grade manganese rock chip results encountered over the Wandanya Project contain approximately 20% more manganese than previous surface mineralisation we have sampled related to manganese enriched shales which commonly range between 25 and 35% Mn. The 50% plus Mn grades at Wandanya are more akin to those related to hydrothermal or contact style manganese enrichment which presents a new targeting opportunity for the Company.
“These early results are very encouraging given the grade of samples and similarities in geological setting to the Woodie Woodie manganese mine. The outcrop is approximately 300m long and 150m wide and to the north there appears to be further mineralisation that will be followed up with mapping and additional sampling.”

Wandanya Manganese Mineralisation
The high-grade manganese mineralisation encountered at the W2 prospect outcrops over 300m strike and is up to 150m wide forming a gently sloping rounded hill. The mineralisation has been mapped as a mixed manganese dominant ferruginised breccia, with some relict bedding and hosted by dolomite. The area is structurally complex with multiple NE and NW-trending cross cutting faults mapped from aerial imagery. Further work is planned to evaluate the significance of the discovery which will include the evaluation of sub-cropping manganese mineralisation interpreted to the north and along strike that extends discontinuously for a further 1 to 2km.

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.”
