Widespread manganese confirmed at Flanagan Bore prospect in the Pilbara
Outcropping manganese and newly identified historic drilling results further highlight potential to expand known mineralisation
HIGHLIGHTS
-
Field assessment confirms widespread manganese mineralisation and highlights scope to extend mineralisation at Flanagan Bore outlined by previous drilling
-
Two new highly prospective manganese target areas identified
-
Surface manganese mineralisation was observed over an area of 1000m x 900m at the FB1 prospect, where recently identified historic drilling intersected significant intervals, including;
-
18m @ 11.2% Mn from surface (WD0020)
-
3m @ 21% Mn from surface and 20m @ 12.5% Mn from 8m (WD0021)
-
24m @ 10.3% Mn from surface (WD0024)
-
At the FB3 & FB4 Prospects, widespread folded manganese-enriched shales are exposed over a strike of ~400m and have not been drill tested
-
Surface mineralisation has been identified 500m to the south of thick manganese intervals previously drilled over an area of 1000m x 200m at the LR1 prospect
-
Highly experienced geologist Jeremy Aldworth appointed Exploration Manager
-
Drilling is planned for the coming quarter
Black Canyon (ASX: BCA) is pleased to advise that a field assessment of its Flanagan Bore manganese prospect in the Pilbara has confirmed the presence of extensive mineralisation at surface and highlighted significant scope to grow the known mineralisation in several areas.
Located 120km northeast of Newman, Black Canyon’s Flanagan Bore tenement is part of the Company’s Carawine Project and is subject to a farm-in and joint venture agreement with Carawine Resources Ltd (ASX:CWX) whereby Black Canyon can earn up to a 75% interest in the Carawine Project tenements.
The field assessment, led by Black Canyon Executive Director Brendan Cummins, confirmed outcropping manganese-enriched shales from the prospective Balfour Formation at the predicted

locations and identified several new prospect areas that have not been adequately drill tested (Figure 2). These include the:
-
FB1/FB2 Prospects, which comprise folded manganese shales with the thicker more prominent bands of manganese-enriched shale forming topographic rises (Figure 5). Data from eight previous drill holes located across a 1000m x 900m footprint at the FB1 prospect confirm grade and thickness potential;
-
FB3/FB4 Prospects, which show widespread areas of outcropping and sub-cropping manganese-enriched shale exposed over a strike of 400m and mapped down dip a further 650m (Figure 4). There is no evidence of previous drilling in the area.
The 900m x 200m extent and flat lying nature of manganese mineralisation previously drilled at LR1 was confirmed and further surface mineralisation has been identified up to 500m south of the current drill area – refer to Figure 3 (ASX Announcement dated 17/05/2021 “Exploration to Commence over the Pilbara Manganese projects).
In light of the strong results from the field trip, Black Canyon has scheduled drilling to start at Flanagan Bore in the coming quarter.
Black Canyon Executive Director Brendan Cummins said: “We have immense exploration upside at our Pilbara projects and our strategy to unlock this value has been given a huge boost by the appointment of Jeremy Aldworth as Exploration Manager. I have worked previously with Jeremy, during which time we added significant value through the discovery and expansion of several economic mineral sands resources in Tanzania. We hope to replicate this success at Back Canyon with our portfolio of quality assets in the eastern Pilbara.”
“One such asset is the Flanagan Bore Project which has potential to host significant manganese mineralisation. With one field trip we have be able to reconcile the thick drill intersections ranging 10m to 37m previously encountered at the LR1 prospect. After walking the ground and comparing the geology of the LR1 prospect to the new prospects associated with widespread manganese-enriched shale, we are hopeful that the potential thickness of the target manganese horizon may have similar ranges.”
“The potential is further confirmed with the discovery of a shallow plunging fold/limb structures across the Flanagan Bore tenement and we look forward to drill testing these targets in the coming quarter.”

The Company continues to review the extensive historic database across the Carawine project tenements to establish new targets, including several with the potential for high-grade hydrothermal style mineralisation, particularly along the Fig Tree corridor, 35km south of the operating Woodie-Woodie manganese mine. A further field program is planned to evaluate these opportunities in the coming weeks.

Flanagan Bore Mapping Summary
LR1 prospect
Previous drilling at LR1 encountered thick intervals of manganese-enriched shales with a maximum thickness of 37m. The previous drilling has shown a mineralisation footprint in the order of 900 x 200m and the recent field investigations confirmed the flat-lying nature of the mineralisation and identified subcropping mineralisation a further 500m to south that appears to be part of the same horizon (Figure 2). This suggests the prospect is open at least another 500m to the south of the current drilling and remains open to the east under cover.
Significant results from the earlier program include:
-
LRRC08 - 37m @ 12.8% Mn from 3m
-
LRRC16 - 33m @ 11.3% Mn from surface
-
LRRC03 - 28m @ 11.9% Mn from 4m
Further manganese mineralisation maybe encountered under extensive sheetwash areas to the south and around the fold hinge to the north.
FB1/FB2 prospect:
The manganese-enriched shales form a sequence of folds and comprise manganese shales with the thicker more prominent bands of manganese-enriched shale forming topographic rises. The fold noses appear to be buried under shallow cover (Figure 4).
Eight previous drill collars were identified covering an area of 1000m x 900m. The drill data has now been digitally captured and are summarised in Table 1. The mostly vertical down hole intersections ranged in thickness from 3m to 30m with an average weighted grade of 10.5% Mn and 8.2% Fe. Significant results from the previous drilling include:
-
18m @ 11.2% Mn from surface (WD0020)
-
3m @ 21% Mn from surface and 20m @ 12.5% Mn from 8m (WD0021)
-
24m @ 10.3% Mn from surface (WD0024)

provided a good understanding of the thickness of the prospective Balfour Formation and the potential of the FB1 prospect.
FB3/FB4 prospects
The FB3 prospect is defined by an arcuate synclinal fold nose plunging shallowly to the southwest with widespread areas of outcropping and sub-cropping manganese-enriched shale. The main fold nose is exposed over a strike of 400m and the interpreted shallow down plunge expression mapped up to 650m to the southwest (Figure 3). There is significant manganese-enriched shale remaining on surface at FB3 due to the subsequent weathering and removal of the softer interbedded clays and shales.
The FB4 prospect also shows a 500m long ridge of sub-cropping manganese-enriched shale underlain and interbedded with calcareous manganese shales.
The prospects have not received drilling to date and will be a priority target for drill testing in the next quarter.
FB5 Prospect
The FB5 prospect comprises a shallow west dipping sequence of manganese enriched shale underlain by calcareous manganese rich shales and dolomites progressively to the east. Only a small section of the 5000m long zone of manganese mineralisation has been mapped and the target has high potential to form a substantial zone of manganese enrichment.

About Black Canyon
Black Canyon has entered into a farmin and joint venture with ASX listed Carawine Resources Limited (ASX:CWX) to acquire a majority interest in the Carawine Project in Western Australia. The Carawine Project covers approximately 800km[2] of tenure located south of the operating Woodie-Woodie manganese mine, providing a large footprint in a proven and producing manganese belt. Black Canyon has also applied directly for another exploration license adjacent to the Carawine Project that would increase the total land holdings to over 1400km[2] on grant. In addition to manganese, the Carawine Project also hosts multiple copper occurrences including the Western Star prospect which comprises a large zone of surface copper enrichment.
==> picture [310 x 262] intentionally omitted <==
The Company has also secured the Lofty Range manganese project located immediately to the west of the Butcherbird manganese deposit being developed by Element 25.
Manganese and copper continue to have attractive fundamentals with growing utilization in the battery mineral sector and challenging supply conditions.

• Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. |
• Selective sampling based on field observation and outcrops identified as hosting potential for mineralisation. • Should not be considered representative of the rock mass as a whole but an indication of the local grade at surface |
| Orientation of data in relation to geological structure |
• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Samples are representative only of the material sampled and based on surface outcrops it is unknown if the samples have a bias related to orientation of structures or mineralised horizons. |
| Criteria | JORC Code explanation | Commentary |

| Sample security | • The measures taken to ensure sample security. |
• The samples are generally placed in a calico bag and then secured in a polyweave bag that is zip locked. • This is not considered a high risk given the Project location. |
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data. |
• Not applicable at this early stage of exploration |
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| • Criteria |
• JORC Code explanation |
• Commentary |
|
|---|---|---|---|
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• The samples were taken from BCA JV license E46/1301) • The samples reported are located within the boundaries of the Black Canyon JV license. • Black Canyon has a farm-in and joint venture agreement with Carawine Resources Ltd (ASX:CWX), giving Black Canyon the right to earn an initial 51% interest and up to 75% in the Carawine Projects. • The tenements from which the samples were taken are subject to native title but are consider non-earth disturbing activities and generally do not require a Heritage Survey |
|
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• The samples presented in the release have been collected by previous Companies and collated by BCA |
|
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The geology and mineralisation is described in the body of the release |
|
| Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• Not applicable to rockchips results |
|
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• All sample results are listed in Appendix 3 and shown in the figures within the body of the release. |
|
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
• No drill widths or intervals reported |
|
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be |

| limited to a plan view of drill hole collar locations and appropriate sectional views. |
||
| Balanced reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• All information considered material to the reader’s understanding and context of the Exploration Results have been reported. • All rockchip data has been reported in Appendix 3 |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• Information relating to the most advanced data from the primary prospects on the tenement have been reported. • Surface investigations have been conducted at this tenement and is summarised in the plan within the body of the report. • All information considered material to the reader’s understanding and context of the Exploration Results has been reported. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• Planned worked programs include surface mapping and geochemical verification • RC drilling and analysis on selected targets |
