Focus Graphite Pilot Run Demonstrates Significant Increase in Large and Jumbo Flake Recovery at Lac Knife

Lac Knife Graphite satisfies and goes beyond U.S. DoD requirements while providing ~ 47wt.% big flake healing for sophisticated product markets in current pilot run performed by AETC

Ottawa, Ontario–(ACN Newswire – September 2, 2025) – Focus Graphite Inc. (TSXV: FMS) (OTCQB: FCSMF) (FSE: FKC0) (“Focus” or the “Company“a Canadian designer of top-quality flake graphite deposits in Quebec, is happy to reveal arise from a constant pilot beneficiation program carried out by American Energy Technologies Company (“AETC”on its 100%-owned Lac Knife task. The modification from 97.8% overall graphite material (“TGC“to 95% TGC led to a significant boost in coarse flake healing. Big and jumbo flakes increased from roughly 33% to 47%, materially enhancing economics and diversifying market chances in an item portfolio technique prepared by Focus.

To attain these outcomes, Focus commissioned AETC to run an upstream beneficiation circuit including 18 processing systems linked in series in a constant locked-cycle project. Over 800 kgs of Lac Knife graphite-bearing rock was processed, producing a concentrate that not just fulfilled market specs however likewise maintained natural flake size. By producing concentrate in line with real-world need requirements, Focus makes the most of downstream worth while boosting direct exposure to premium, non-battery markets.

In Focus’s initial pilot plant screening program carried out at SGS Minerals (“SGS“in Lakefield (2013-2014), the goal of attaining a graphite concentrate grade of 97.8% TGC at 90.7% overall healing was effectively satisfied. These outcomes formed the technical structure of the Lac Knife Feasibility Study (upgraded 2023), which described a procedure plant developed to produce 50,000 tonnes annually of graphite concentrate, consisting of 47,781 tonnes of state-of-the-art 97.8% TGC trafficable concentrate from a feed grade of 14.8% TGC. The procedure circulation sheet established through this work consists of squashing, grinding, polishing, flotation, concentrate dewatering and drying, focus screening and bagging, and tailings purification and loadout. While the Feasibility Study showed Lac Knife’s capability to provide ultra-high-purity graphite, subsequent market feedback validated that such high pureness are not needed – and do not command a rate premium – in the majority of anode or commercial applications.

As a criteria, the U.S. Defense Logistics Agency (“DLA“Strategic Materials program has actually specified procurement requirements for natural graphite as -100 mesh concentrate. Lac Knife product conveniently surpasses U.S. defense-grade requirements, while concurrently lining up with anode makers’ specs for EVs and fixed energy storage.
