Australian manganese explorer, Black Canyon Limited (Black Canyon or the Company) (ASX:BCA), is pleased to announce it has completed drilling 7,534m of RC drilling as part of an infill and extensional drilling program across the previously announced Mineral Resource at Flanagan Bore comprising 104Mt @ 10.5% Mn (Indicated) containing 11Mt of manganese (Table 1).
The infill drill program was designed to focus on an outcropping high-grade manganese subset of the Mineral Resource estimate, comprising 33Mt @ 12.8% Mn (Table 2) across the FB3 and LR1 deposits.
ForThe drill program also evaluated the potential of the strike between FB3 and LR1 deposits and yielded promising results as additional shale enriched manganese mineralisation was intersected. Assays are pending.
Black Canyon Executive Director, Brendan Cummins, said: "The fast-trackeddrill program completed at Flanagan Bore will provide additional tonnage potential from both the FB3 and LR1 deposits with manganese mineralisation now successfully identified between the two deposits. The infill drill results should also enable an upgrade in mineral resource confidence classification from the current Indicated to Measured status which can be used for detailed feasibility studies".
"The Company is also advancing metallurgical studies with acid leaching testwork applied to manganese concentrates derived from the Flanagan Bore deposits. This initial leaching testwork is a crucial first step

Flanagan Bore is part of the Company's Carawine JV and is subject to a farm-in and joint venture agreement with Carawine Resources Ltd (ASX:CWX). Having earned a 51% interest, Black Canyon is now earning up to 75% in the Carawine Project tenements by sole-funding an additional $2.5m of xploration expenditure. The Flanagan Bore Project is located approximately 400 km southeast of Port
Hedland in the east Pilbara region of Western Australia.
As a result of the completed RC drill program (181 holes for 7,534m), the overall drill spacing at FB3 and
centred holes. Significantly, the doubling of the drill density should enable the current Indicated classified ForMineral Resources to be upgraded to Measured, which is suitable for detailed feasibility and associated mining and processing studies. No further mineral resource drilling is required once Measured Mineral Resources have been estimated. In addition, all of the project drill collars have now been located using highly accurate differential global positioning system (DGPS) and the December 2021 drill holes have also been down-hole surveyed for density, gamma and magnetic susceptibility. The down-hole data will be
used with more detailed geological domaining and interpretation.
Three additional manganese-enriched shale targets were also successfully drilled along 2km of strike connecting the FB3 and LR1 deposits, and mineralisation was confirmed at the FB2 and FB6 prospects (Figure 1).
Assays are pending and expected to be received over the next 2 to 3 months.

About Black Canyon |
Black Canyon has entered into a farm-in 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 800 km2 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 for and acquired other exploration licenses adjacent to the Carawine Project that would increase the total land holdings to over 2600 km2 upon 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.
Manganese and copper continue to have attractive fundamentals with growing utilisation in the battery mineral sector and challenging supply conditions.
