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.

BCA:AU
High grade Assay Results Continue at Youanmi
- The latest batch of assays have been received from the 11,000m drilling program (both diamond core and reverse circulation) at the high gold-grade Youanmi Gold Project, located centrally in Western Australia’s prolific gold fields
- The recently-completed infill/exploration program aimed to improve resource confidence and open up corridors for resource growth; to underpin the Definitive Feasibility Study (DFS), and, additionally, provide sample material for ongoing metallurgical optimisation test-work for the DFS program
- Latest highlights from the program include:
- RXDD131: 4.38m @ 19.07 g/t Au from 387.98m,
- incl. 1.73m @ 41.43 g/t Au from 389.96m
- RXDD119: 4.56m @ 14.60 g/t Au from 220.64m
- RXDD115: 2.99m @ 21.11 g/t Au from 249.88m
- RXDD119: 4.0m @ 7.37 g/t Au from 162.0m
- RXDD132: 7.19m @ 3.90 g/t Au from 263.61m
- RXDD133: 2.83m @ 6.53 g/t Au from 431.00m
- RXDD128: 3.82m @ 4.51 g/t Au from 364.59m,
- incl. 1.73m @ 8.22 g/t Au from 364.59m
- incl. 1.73m @ 8.22 g/t Au from 364.59m
- RXDD122: 0.95m @ 13.50 g/t Au from 204.44m
- §These results further demonstrate the continuity of high- grade gold mineralisation along the Youanmi greenstone belt belt, and the potential for resource growth both at depth and along-strike, with discovery potential to the south
- 35,000m Step-up drill campaign well underway with the plan to bring forward ounces and increase the mine plan
The program focused on converting Inferred stopes at Pollard, United North and Youanmi Main to higher confidence Indicated classification and providing material for metallurgical testing for the upcoming Definitive Feasibility Study (DFS) – on track for H2 CY25.
This final consignment of diamond assay results are the fourth batch of assays results returned from the drill program and have been entirely drilled from the Pollard, Youanmi and United North areas (Figure 1).
Rox Resources’ Chief Executive Officer, Phillip Wilding, commented:
“It’s pleasing to round out the 11,000m RD and DD drilling program with another batch of excellent intercepts.
“More importantly, the program has significantly improved our knowledge of the high grade and underexplored Youanmi ore system, and shown that mineralisation remains open at depth.
“Next steps are to convert Inferred areas of the Resource to the higher confidence Indicated classification, and finalise key intercepts of sample material for metallurgical test work to feed into the Youanmi DFS.
“We are excited to have commenced the 35,000m Step-up program to potentially bring forward ounces in the mine plan and significantly increase the size of the Pollard ore zone.”
Youanmi Major Growth Drill program
Resource drilling has focused on converting selected Inferred stopes in the current Mineral Resource of 16.2Mt at 4.4g/t Au for 2.3Moz (Indicated: 10.7Mt at 4.5g/t Au for 1.6 Moz : Inferred 5.5Mt at 4.2g/t Au for 0.7 Moz) 1 to higher confidence Indicated classification at Pollard, United North and Youanmi Main as shown in plan on Figure 1. The drilling has also provided both sample material for metallurgical testing and valuable geological data for the pending Definitive Feasibility Study (“DFS”) planned for second half of 2025.

Outside of the immediate resource area, drilling was also conducted on near-mine exploration and focused on the Youanmi South prospect area, or Paddy’s Lode, first reporting high-grade intercepts in 20232. The drilling at Paddy’s has complimented the Company’s exploration strategy moving south along the Main Lode Shear Zone (MLSZ) and adding additional gold ounces to the Resource. Youanmi South has the potential to grow the Resource above the 103kozpa Production Target outlined in the recently completed Pre-Feasibility Study (“PFS”)3.

Drilling Commenced at Viani in Fiji
HIGHLIGHTS
- The Phase 1, three-hole diamond drilling program has commenced at the Viani Project, Fiji and will test for extensions to the quartz vein gold mineralisation at depth.
- Phase 1 is expected to be completed in early 2025, with plans for additional drilling under the same program dependent on the initial results
- The Viani Project (SPL1513) covers an area of approximately 200km2 and is largely underexplored.
- At the Dakuniba prospect within Viani, low sulphidation epithermal high-grade gold mineralisation has been mapped over >3km strike length.
- Diamond drilling completed by Japan International Cooperation Agency (JICA) in 1995 to 1997 intersected high-grade gold in low sulphidation epithermal quartz veins, including 0.6m @ 27.6 g/t Au.
Alice Queen’s Managing Director, Andrew Buxton said,
With drilling underway, Alice Queen is positioned to test the epithermal gold-style mineralisation identified in historic drilling at the Viani Project. Weather permitting, we anticipate completing the Phase 1, three-hole diamond drilling program in early 2025. Following this, our exploration team will mobilise the drill rig to the Sabeto Project in Fiji to maintain the momentum of this campaign. To deliver timely results to shareholders, we intend to accelerate the analysis of the drill core at ALS Brisbane.”

Details
Geology
The geology of the Viani Project (SPL 1513) comprises olivine basalts and volcaniclastics of the Natewa Volcanic Group which are intruded by andesite sills and dykes. In the 1940s, gold mineralisation was found by local prospectors near the village of Dakuniba. At Dakuniba, low sulphidation style epithermal gold occurs in quartz veins, and silicified rocks along a 3km long NE trending zone.
In 1995-1997, Japan International Cooperation Agency (JICA) drilled six diamond holes at Dakuniba and intersected high-grade gold in chalcedonic, crustiform, colloform banded quartz veins at depths of 50m to 100m below surface (i.e. MJVFV-5 intersected 2.2m @ 11.3 g/t Au, incl 0.6m @ 27.6 g/t Au at 121m downhole). This high-grade gold mineralisation is open in all directions.
Proposed Drill program
The initial Phase 1 drill program at Viani (see Table 1) will comprise three diamond drillholes designed to test continuity to the epithermal gold mineralisation previously intersected in JICA drillhole MJVFV- 5 (2.2m @ 11.3 g/t Au) (see Figure 2). The drilling will test for extensions to the gold mineralisation at depth and along strike.
