Highlights
- Dense Media Separation (DMS) techniques yielded manganese concentrate grades of 31.8% Mn and 31.3% Mn for KR1 and KR2, respectively.
- Previous Heavy Liquid Separation (HLS) results showed concentrate grades ranging from 29.2% Mn to 37.4% Mn for KR1 and KR2.
- The DMS results confirm the company can produce a 30–33% manganese oxide product.
- These findings will shape the assumptions of the KR1 and KR2 scoping study, expected by June end.
Black Canyon Limited (ASX: BCA) has shared an encouraging development concerning the production of beneficiated manganese concentrate feedstock from the KR1 and KR2 deposits.
With the use of DMS techniques based on industry standards, the company reported Mn concentrate grades of 31.8% Mn and 31.3% Mn from the KR1 and KR2 samples, respectively. These findings complement the previously shared outcomes from Heavy Liquid Separation (HLS), which indicated concentrate grades ranging between 29.2% Mn and 37.4% Mn, from KR1 and KR2.
The metallurgical results from DMS affirm that the company can produce a 30–33% manganese oxide product, which is highly desired in the high-volume medium grade manganese market.
The DMS findings will contribute to shaping the assumptions of the KR1 and KR2 scoping study, which is advancing well and is expected to be completed by the end of the quarter.
BCA shares traded at AU$0.10 apiece at the time of writing on 1 May 2024.
