Black Canyon (ASX: BCA) reports manganese concentrate grades above 30% in metallurgical testwork - Kalkine Media

Highlights

• BCA is a manganese (Mn) explorer holding a 75% interest in the Carawine joint venture with Carawine Resources
• Composite samples from the Flanagan Bore Project have shown Mn concentrate grades between 30% and 33% in the latest metallurgical testwork
• BCA says the results show consistency across the composites tested in terms of lump and fines Mn

Black Canyon (ASX: BCA) -- the company with interests in the Carawine joint venture (manganese and copper) -- has provided a positive update with respect to the recently completed metallurgical testwork. The testwork used two samples from the LR1 and FB3 deposits (Flanagan Bore Project) and achieved manganese (Mn) concentrate grades up to 33%. BCA is progressing discussions with potential off-take partners, and additional testwork to test the variability acrossthe Company's tenements.

The ASX-listed shares of the manganese explorer and developer last traded at AU$0.265 midday on 17 April 2023, with BCA's total market cap of AU$13.7 million.

The development

The manganese explorer and developer in Western Australia undertook metallurgical testwork of composite samples at the Flanagan Bore Project, with results now showing concentrate grades up to 33% Mn. The master composites belonged to the LR1 and FB3 deposits. The company believes that the result provides "further confidence" to deliver "consistent and reliable" Mn product using the density separation technique.

The pre-feasibility level test work was aimed to understand material characteristics and potential flowsheet design besides other things. The company is also prepping for further laboratory scale testwork to enhance the findings of the metallurgical testwork. Manganese content upgrades from scrubbing and washing are in the below picture (Figure 1), followed by upgrades using density liquids applied to lumps and fines (Figure 2).

Statement

The company's Executive Director Brendan Cummins has lauded the metallurgical update development and commented that it "builds significantly upon" 2022's Scoping Study testwork. Last year, the company has compared heavy liquid separation to ore sorting processing. Mr. Brendan has also stated that Black Canyon would progress other potential resource targets, across the company's diverse portfolio, over the next 6 months.
