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.

EIS Grant for Minnie Springs Copper Porphyry Drilling
- Augustus Minerals has been granted a co-funded drilling grant of up to $110,000 for 2 x 700m deep diamond drill holes under the WA Government’s Exploration Incentive Scheme (EIS) for the Minnie Springs prospect.
- The deeper diamond drill program is designed to test and to provide a 550m deep, 1km wide geological/geochemical/structural cross-section through the large 3km long by 1km wide copper moly porphyry system, linking the Mo mineralised leucogranite to the extensive Cu in soil anomaly to the northeast.
- Previous RC drilling at Minnie Springs intersected mineralisation, geology and alteration halo consistent with the zoning of a large porphyry copper / moly system.
Andrew Ford, GM Exploration
“The Company is pleased to receive an EIS grant to complete deeper drilling at the Minnie Springs Copper Molybdenum Project. The resultant data will enable mapping of the lithology and alteration to a depth of 550m and potentially intersect, or provide vectors to, higher grade Mo-Cu mineralisation using a Mo-Cu porphyry geological model”.
Minnie Springs
Minnie Springs hosts porphyry related copper molybdenum mineralisation previously drilled and defined by Catalyst Metals. A molybdenum Exploration target has been defined for the historicdrillingareacomprisedofbetween12-84Mtasoutlinedbelow (Table 1 and Figure 1, 2.)1.
Table 1. Exploration target size estimate for Minnie Springs Molybdenum depositNote: Based on ~300 ppm cut-off at 100% recovery.
The potential quantity and grade of the exploration target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resources, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The planned diamond drilling will complement the recently completed 3,200m RC drilling program that infilled around hole MSRC012 (18m @ 0.37% Cu and 9.7 g/t Ag from 94m downhole, and 16m @ 0.38% Cu and 19.4g/t Ag from 121m downhole2) and tested the northern half of the 2km long copper-in soil anomaly. Assays from this program are expected to become available over the next month.
The limited exploration in the region, highlighted by 95% of the Ti-Tree project having no previous exploration, demonstrates the prospectivity of this underexplored mineral province.

Quarterly Activity Report 31 March 2024
Figure 1. Fiery Creek Copper Prospect/Yataga Granodiorite summarizing rock (brown diamonds) and termite mound sample results (black crosses)
Continuing with its primary exploration focus on the Georgetown project in the latter half of 2023, EMU received assay results during the quarter from its second, in field reconnaissance work. The geochemical sampling programme covered the Fiery Creek high grade copper vein swarm and the Snake Creek prospects with significant element results returned from the Fiery Creek Copper (elevated Cu-Au-Ag-Bi-In-Pb-Sb-Te) and Snake Creek (elevated Pb-Ag-Au-Sb).
Whilst the survey was cut short due to inclement weather, EMU was encouraged by the significant success reflected in the assays results. The results from mineralogical studies confirmed EMU’s interpretation of an indicative, scale Copper-Porphyry system at the Fiery Creek prospect and was a highlight of the survey with new information building on the scale and potential of the prospect1.
Assay results returned included:
- Fiery Creek rock assay results up to 23.5% Cu, 0.27ppm Au, 460ppm Ag, 1.9% Bi, 89ppm In, 2.7% Pb, 667ppm Sb, 1470ppm Zn2.
- evidence of strong potential for the presence of critical and strategic minerals (Cu, Bi, In), with precious and base metals.
- evidence of alteration mineralogy, mineralisation geochemistry and areal extent of the Fiery Creek quartz-Cu-Bi vein swarm strongly suggesting a previously unrecognised subjacent porphyry Cu-Mo system.
- Yataga Granitoid Complex termite mound and coincident rock chip sampling returned several anomalous polymetallic zones for follow up.
- Snake Creek Prospect assays returned 0.20ppm Au, 390ppm Ag, 22.4% Pb, 464ppm Sb1.
Significant results were returned from the Fiery Creek Copper prospect with elevated Cu-Au- Ag-Bi-In-Pb-Sb-Te and from the Snake Creek prospect with elevated Pb-Ag-Au-Sb.
The elevated pathfinder element results and a macro-petrology assessment3 of rock samples completed by Mr Nigel Maund, Consulting Economic Geologist, from the previously unexplored Fiery Creek Prospect, point to the discovery of a porphyry copper system.
The sampling program assessed a number of high-priority prospects within the Georgetown Project tenements utilising termite mound and outcrop rock chip geochemistry. A total of 46 rock chip and 489 termite mound samples were collected across eight prospects.
