grade zones from surface with the following significant results: | |||
o 39m @ 13.5% Mn from surface (FBRC060) | |||

• The exceptional drill results pave the way for a maiden Mineral Resource to be estimated | |||
at FB3, in conjunction with the expanded mineral resource estimate at LR1 located 4km to the west, with results of this work due in April 2022
• Updated Mineral Resources from FB3 and LR1 are expected to significantly increase the current Inferred Mineral Resource estimate for the project of 15Mt @ 11.3% Mn and provide a solid platform to underpin the current Scoping Study
Australian manganese explorer, Black Canyon Limited (the Company)(ASX:BCA), is pleased to announce the discovery of thick, shallow manganese enriched shales at the FB3 prospect at Flanagan Bore. The assay results from the FB3 RC drill program completed in December 2021 have been received and

demonstrate widespread manganese mineralisation with several high-grade intersections reported from surface. The drill results will now be incorporated into a maiden Mineral Resource Estimate for FB3 in addition to the anticipated mineral resource upgrade to increase the current mineral resource at LR1 onlycomprising 15Mt @ 11.3% Mn1. This will significantly increase the global Mineral Resource at Flanagan
Bore.
Black Canyon's Executive Director, Brendan Cummins, said "The Flanagan Bore Project has delivered further outstanding and continuous zones of manganese enriched shale containing shallow high- grade intervals. The discovery of the complementary mineralisation at FB3, located only 4km to the west f LR1 will help to build mineral resources and adds significant value to the Flanagan Bore Project due to
the shallow nature of the high-grade intersections.
The Company is in an enviable position to accelerate mineral resource estimates for the FB3 and LR1 usedeposits, with results due in April to set up a solid foundation to underpin the current Scoping Study and
developing production targets".
Located 120km north-east 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 (the Agreement) with Carawine Resources Ltd (ASX:CWX) whereby Black Canyon can earn up to a 75% interest in the Carawine JV Project tenements.

Flanagan Bore Drill Program Summary
A total of 168 RC drill holes were completed for 5,569 metres and 13 PQ diamond drill core holes were completed for 477 metres. The Company has received and compiled the assay results from the first 127 onlyRC drill holes from the LR1 and FB3/FB4 deposit areas. A summary of the significant results is provided
below and collar details for the drill program completed at FB3 are presented in Appendix 1.
FB3/FB4 Prospects
A total of 82 holes for 2,148m were drilled into the FB3 and adjacent FB4 prospects.
The RC drilling program encountered widespread manganese mineralisation across both the FB3 and FB4 prospects covering an area 1000m x 1000m, using a broad 200m x 100m grid drill pattern. There had usebeen no previous drilling at FB3/FB4 and the assays results have now confirmed the discovery of thick
manganese enriched shales at FB3/FB4. Several holes ended in mineralisation and remain open at depth. Future RC drill programs will be drilled deeper to determine the full extents of the manganese enriched
hales down hole and down plunge.
Structurally the mineralisation found within the FB3 prospect is defined within an open southwest plunging synclinal fold. The northern limb appears to be dipping slightly steeper than the southern limb which is close to flat. Higher manganese grade zones are coincident with an increase in topography across the fold nose and northern limb.
Significant results for the FB3/FB4 prospects are shown in plan and cross-section in Figures 1 & 2 respectively and are also listed below:

personalLR1 Mineral Resource Extension Assay Results
A 900m x 200m zone was historically drill tested in 2013 and an Inferred Mineral Resource estimated, comprising 15Mt @ 11.3% Mn1.
As previously reported (see ASX announcements dated 8 and 21 February 2022), the assays received from the RC drill program at LR1 confirmed extensions to the mineralisation to the southwest with 400m to 600m additional cross-strike width now defined. The mineralisation footprint is 1100m long and up to 800m wide based on the results received from the RC drilling program. The mineralisation is open to the west but appears to be offset to the NE which will require additional drilling to confirm. Infill drilling is planned and will be undertaken during the 2022 field season
Significant results from LR1 are listed below and cross-section provided in Figure 3:
