Australian manganese explorer and developer, Black Canyon Limited (Black Canyon or the Company) (ASX: BCA) is pleased to announce the expedited laboratory-based assay results from the W2 prospect Reverse Circulation (RC) drill program. The maiden drill program identified high- grade hydrothermal related stratabound manganese mineralisation with these assay results confirming the initial pXRF results2
HIGHLIGHTS
- Significant high-grade manganese assays received for the W2 prospect1, Wandanya located 80 km south of the Woodie Woodie Manganese Mine including:
- 5m @ 33.2% Mn from 4m including 2m @ 48.7% Mn (WDRC032)
- 5m @ 33.2% Mn from 1m including 2m @ 44.1% Mn (WDRC031)
- 5m @ 32.4% Mn from 4m including 2m @ 3G.6% Mn (WDRC027
- 6m @ 27.7% Mn from 3m including 2m @ 42.G% Mn (WDRC013)
- The stratabound mineralisation shows remarkable thickness and grade consistency over 240m of drilled strike and remains open to the east and north where the Company has mapped 1.75km of intermittent high grade outcropping manganese
- W2 is interpreted as stratabound, fault related hydrothermal manganese enrichment representing a significant new exploration model on the eastern margin of the Oakover Basin.
- Metallurgical testwork planned to produce a high-grade Mn concentrate as a feedstock for alloying or high purity manganese sulphate (HPMSM)
Black Canyon’s Managing Director Brendan Cummins said:
“The laboratory-based assay results have confirmed the significant high-grade intercepts for the W2 prospect. I am impressed by the consistency of the grades and thickness of the manganese horizon we have discovered and the higher-grade intervals over 40% Mn. What is really appealing about this target from an exploration and resource delineation perspective is the benefit of a consistent mineralised horizon that is also associated with hydrothermal grades. I am excited by the upside of this new style of mineralisation as we plan our follow-up exploration programs to assess 1.75km of strike to the north and the potential of the manganese horizon to extend to the east.”

W2 Prospect, Wandanya (BCA 100%)
The W2 prospect was drilled on an approximate 40 x 40m grid testing a 240 long x 200m wide target. This drill program comprised 35 holes for 642m of drilling. Drill collar information is presented in Appendix 2.
Expedited Assay Results
Initially, six RC holes were sampled for expedited assays, generating 38 one metre interval samples that were gathered along the eastern boundary of the stratabound mineralisation. Representative holes were sampled from every second line along the drilled strike of 240m. On each drill line, the last two eastern holes were sampled from depths between 4m and 9m, which included stratabound mineralisation and portions of the lower grade footwall and hangingwall.
The results are presented in Table 1, which show consistent zones of mineralisation with the bottom 2m for each intersection typically returning high grade mineralisation potentially suitable for direct shipping (DSO).

High grade Massive Sulphide Intercepts Confirmed at Oval
HIGHLIGHTS:
- OVD027 confirms the continution of high grade massive sulphide from OVD0211 with an intercept of 6.1 metres of 4.16% Cu, 3.51% Ni, 0.G3g/t E3, and 0.13% Co from G8.2 metres encountered between broader high grade zones of:
- A dense disseminated intercept - 26.2 metres of 0.44% Cu, 0.52% Ni, 0.12g/t E3, and 0.03% Co from 72.0 metres and
- A net textured intercept - 15.3 metres of 1.15% Cu, 0.79% Ni, 0.35g/t E3, and 0.04% Co from 104.3 metres;
- A high grade broad intersection is confirmed at the central part of the Oval area by OVD026. It includes a massive sulphide intercept in hole OVD026 of 1.8 metres of 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co from 105.0 metres within broader mineralisation of:
- 19.8 metres of 1.23% Cu, 0.98% Ni, 0.36g/t E3, and 0.05% Co from 91.2 metres.
OVD026 is located 100 metres northwest of the previously announced 8.8 metres of massive sulphide identified in drillhole OVD021.
On completion of the Phase 2 exploration work and receipt of all assays, Managing Director Gan-Ochir Zunduisuren, commented:“The 2024 Phase 1 and 2 drilling and exploration programs have confirmed the broad presence of high-grade mineralisation in the Oval gabbroic intrusion. The grades intercepted in some of the drillholes are exceptional and may be indicative of broader potential over a larger area, given Oval is a greenfields discovery.
The 2025 exploration program will focus on obtaining information on the size/metal content potential of the Oval Cu-Ni-PGE mineral system as well as targeting the possible deeper magmatic sources at Oval. Broader exploration is also planned at potential extensions of Oval and nearby look-a-like prospects. We look forward to updating shareholders on progress, with drilling expected to commence in around 8 weeks”.
Summary of Phase 2 exploration drilling at Oval Cu-Ni-PGE project
The Company’s recent drilling work has predominantly focused on finding high-grade mineralisation in the olivine-amphibole gabbro at the Oval project. The multiple intercepts of massive sulphide mineralisation with different ratios of metal contents throughout the Oval gabbroic intrusion is highly encouraging for the presence of one or more deeper sources of high grade mineralisation in the opinion of ABM.

Drillhole OVD02c
Drillhole OVD026 was designed to test the Down-Hole Electromagnetic (DHEM) conductor plate identified as OVD007_L2_B (reinterpretation of OVD007_L2_A2 by Southern Geoscience Consultants), which exhibits a conductance of 1,000 siemens. The drilling intersected a total of 1G.8 metres of mineralisation with 1.23% Cu, 0.G8% Ni, 0.36g/t E3, and 0.05% Co from G1.2 metres including;
- 4.8 metres of @ 0.45% Cu, 0.43% of Ni, 0.14g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 91.2 metres,
- 6.6 metres of @ 1.56% Cu, 0.G0% Ni, 0.50g/t E3, and 0.04% Co of net textured mineralisation from G6.0 metres,
- 2.4 metres of @ 1.52% Cu, 1.3G% Ni, 0.43g/t E3, and 0.07% Co of semi massive sulphide mineralisation from 102.6 metres,
- 1.8 metres of @ 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co of massive sulphide mineralisation from 105.0 metres, and
- 4.2 metres of @ 0.57% Cu, 0.45% of Ni, 0.21g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 106.9 metres (Table 1 provides a detailed breakdown of mineralisation intervals).
OVD026 is located in the Oval area, which is approximately 100 metres northwest of the previous intersection identified in drillhole OVD0213. This intercept may represent an extension of the known massive sulphide mineralisation in the Oval area and highlights the potential for further expansion of massive sulphide zones within the broader prospect area (Figures 1 and 3).
