Canada Carbon Completes Bulk Sample Program on Its Asbury Graphite Project
Canada Carbon has completed its Bulk Sample Program at the Asbury Graphite Project in Quebec. Working with SGS Lakefield, the program analyzed head assays, Bond Ball Work Index, and flowsheet optimization. The composite drill core samples showed 3.68% graphitic carbon, exceeding the Initial Resource Estimate. The final flotation test achieved combined concentrate grades of >98% total carbon, with +150 mesh and +325 mesh assaying at 99.1% and 99.0% respectively. The optimized flowsheet demonstrated efficient primary processing operation suitable for battery anode applications. The company aims to complete the Pre-Feasibility Study by Q1 2025.

TORONTO, Oct. 24, 2024 (GLOBE NEWSWIRE) -- Canada Carbon Inc. (the “Company”) (TSX-V:CCB), (FF:U7N1) reports that it has completed the Bulk Sample Program for its
- Head assays
- Bond Ball Work Index Analysis
- Flowsheet optimization
Head Assays
As previously reported (see Press Release dated August 8th, 2024), the Company provided three ore samples for the program : BK1 – high grade drill core, BK2 – low grade drill core, and BK3 – a high grade outcrop. These samples were prepared for testing, and a composite of the two drill core samples (BK1 and BK2) was prepared and named Core Comp. The Company believe that the Core Comp will be a fairly representative sample of the overall Asbury deposit.
Carbon speciation analyses of these samples shows graphitic carbon (C(g)) ranging from
Bond Ball Work Index Analysis
Bond Ball Work Index testing was conducted on the three samples, BK1, BK2 and BK3 which produced similar work indices ranging from 14.1 (BK2) to 14.6 (BK1). In comparison with SGS’s database of thousands of ore types, shown in the graph below, the Asbury samples fall in the median range of hardness percentile, ranging from

Flowsheet Optimization
As the figure below indicates, the Company and SGS engaged in a very thorough process of developing and optimizing the evaluate tradeoffs between flake size and purity based on the length of primary and secondary grind cycles and the number of rougher columns or cells through which the concentrate will be cycled. Global operating parameters utilized in the optimized flowsheet are as follows:
Primary Grind: | 18 minutes in 2 kg rod mill @ |
Polishing Grind of Combination Flash & Rougher (Ro) Concentrate: | 15 minutes @ ~ |
+100 M Regrind: | 10 minutes @ ~ |
-100 M Regrind: | 20 minutes @ ~ |
Note: SMM – Stirred Media Mill
In the optimized flowsheet a flash flotation stage was conducted on the crushed ore producing flash rougher concentrates. The flash rougher tailings were ground and a rougher concentrate produced. Two regrind circuits were added down-process from a 100-mesh concentrate screen. The flowsheet then provides for three cleaner columns to follow each of the +100 and -100 mesh lines.
While the company was initially focused on minimizing required grinding power, as well as the potential for preservation of coarse-flake graphite, subsequent testing shows that increased primary grinding eliminates +48 mesh flake from the concentrate profile but results in significant gains in purity. Given the focus on future participation in the battery anode supply chain, producing a higher purity concentrate, which would be easier and cheaper to purify, is ideal for the Company and its potential future clients.
Floatation Tests Results
The Company’s final floatation test achieved combined concentrate grades of greater than
- Primary grind time was increased first from 12 minutes to 15 minutes and then from 12 minutes to 18 minutes.
- The 15-minute primary grind resulted in P80 230 µm, while the 18-minute primary grind resulted in P80 214 µm. However, it was determined that grinding to P80 214 µm is not required.
- Because of the finer primary grind, the +100 M concentrate exceeded our target
95% C(t) grade after screening (achieving96.2% C(t)) and may not need cleaner stages at all. - The -100 M concentrate, after secondary grinding, achieved a
95.2% C(t) grade after the 1st -100 M cleaner, suggesting that the remaining two cleaner stages provided for in the work sheet may not be necessary at all. - It was also critical to note that, in the final floatation test, the Company’s +150 mesh and the +325 mesh assayed out at
99.1% and99.0% C(t) respectively.
Note: In concentrate samples C(t) is assumed equal to C(g) as any carbonates are expected to flow to the tailings.
"The completion of our Bulk Sample Program by SGS Lakefield produced results beyond our expectations. We were able to demonstrate that a composite sample of our ore recorded in-situ grades in excess of the average in our Initial resource estimate. Additionally, we have engineered a flowsheet which produces high Ct concentrate from an efficient primary processing operation. This will allow us to market an anode market product which will be significantly easier and more cost effective to purify. These characteristics are certainly important to the battery anode space, but also attractive across a variety of high margin applications. We intend to ensure that this scalable, exceptional deposit is expeditiously developed and properly positioned to maximize shareholder value." declared Ellerton Castor, CEO of Canada Carbon.
Next Steps
With the Bulk Sample program complete, Canada Carbon will target completion of the Asbury Pre-Feasibility Study by the end of Q1, 2025. Additionally, the results will allow CCB to conduct battery cell testing on the concentrate through Polaris Labs. Finally, the Company will also expand its scope of lab testing to begin qualifying the Asbury concentrate for a variety of additional industry verticals.
