Australian manganese explorer, Black Canyon Limited (Black Canyon or the Company) (ASX:BCA) is pleased to advise that further to its announcement on March 27 2023 it has now completed the 100% acquisition of granted licence E46/1383 (excluding copper rights as outlined below). This acquisition adds a further 351km² to the Company’s prospective manganese portfolio in the eastern Pilbara. Black Canyon’s tenement coverage further consolidates the prospective manganese enriched shale horizon extending across the Balfour Manganese Field that includes Mineral Resources at Flanagan Bore (BCA 75%) and other Mineral Resources at Balfour South, Sixty Sixer, and the past producing manganese mine of Nicholas Downs which are owned by others (Figure 1).
- Black Canyon has completed the 100% acquisition of granted licence E46/1383 (excluding copper rights)
- The strategic acquisition further expands tenure under BCA exploration control over the Balfour Manganese Field by 351km² to total 1,175km².
- The licence contains several outcropping manganese enriched prospects including a significant and continuous zone of mineralisation extending over 5km at KR1.
- No historic drilling has been completed over the outcropping mineralisation providing an opportunity for Black Canyon to discover and deliver additional Mineral Resources.
- The Company has successfully completed Heritage surveys across the targets and received all other approvals to commence a 5,000 to 10,000m RC drill program.
- Multiple drill targets are now ready to be tested in the coming field season.
Black Canyon’s Executive Director Brendan Cummins said: “Our field teams have been very active over the past few months and completed detailed mapping, surface sampling and successfully concluded Heritage Surveys over key targets across the Balfour Manganese field. Based on the work completed to date and our experience in the area we believe there is high potential to discover and delineate substantial Mineral Resources confirming the manganese endowment of this globally significant region. This is similar to the opportunity at Flanagan Bore where the Company made a significant discovery and rapidly delineated mineral resources. The size and scale of the Balfour Manganese Field and the discoveries to date show considerable promise and the completion of this strategic acquisition complements our existing portfolio and contributes to the Company’s overall growth and development strategy”.

Balfour Manganese Field Exploration Drill Program
An initial RC drill program has been designed to drill test several high-quality targets across Black Canyon, 100% owned tenements within the Balfour Manganese Field. Drilling is planned on the following tenements:
1. E46/1383 – at KR1, a previously undrilled 2,500m section of outcropping supergene mineralisation will be drill tested using 200m spaced lines which includes a 900m long section of prominent manganese enriched shale (Figures 2, 3 & 4). At KR2, a previously undrilled subcropping to outcropping 900m long zone of manganese enriched shale will be drill tested.
2. E46/1396 – at the Balfour West target, a 1500m long horizon that is interpreted to be extend from outcropping manganese enriched shales under thin cover will be drill tested. At Balfour East, several wide spaced stratigraphic drill lines are planned to intersect subcropping and thinly covered manganese enriched shales over several kilometres of strike.
3. E46/1404 – at Pickering, a previously undrilled 2,000m long section of the subcropping manganese enriched calcareous shales will be drill tested using 400m spaced lines. The overall length of the Pickering target is 10,000m. At the Damsite prospect, a previously undrilled 500m long subcropping to outcropping zone of manganese enriched shale will be drill tested.
A total of 5,000 to 10,000m of RC drilling is planned for the coming field season across the three tenements with assay results to follow. Refer to ASX announcement 14 February 2023 (Exploration and Manganese Sulphate Update) and 27 March 2023 (Black Canyon acquires strategic tenement within the prospective Balfour Manganese Field) for further information on the drill targets.

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).
