Lac Knife Graphite meets and exceeds U.S. DoD standards while delivering ~47wt.% large flake recovery for advanced material markets in recent pilot run conducted by AETC

Ottawa, Ontario--(ACN Newswire - September 2, 2025) - Focus Graphite Inc. (TSXV: FMS) (OTCQB: FCSMF) (FSE: FKC0) ("Focus" or the "Company") a Canadian developer of high-grade flake graphite deposits in Quebec, is pleased to announce results from a continuous pilot beneficiation program performed by American Energy Technologies Company ("AETC") on its 100%-owned Lac Knife project. The adjustment from 97.8% total graphite content ("TGC") to 95% TGC resulted in a substantial increase in coarse flake recovery. Large and jumbo flakes increased from approximately 33% to 47%, materially improving economics and diversifying market opportunities in a product portfolio approach planned by Focus.

To achieve these results, Focus commissioned AETC to run an upstream beneficiation circuit consisting of 18 processing units connected in series in a continuous locked-cycle campaign. Over 800 kilograms of Lac Knife graphite-bearing rock was processed, producing a concentrate that not only met market specifications but also preserved natural flake size. By producing concentrate in line with real-world demand specifications, Focus maximizes downstream value while enhancing exposure to premium, non-battery markets.

In Focus's original pilot plant testing program conducted at SGS Minerals ("SGS") in Lakefield (2013-2014), the objective of achieving a graphite concentrate grade of 97.8% TGC at 90.7% total recovery was successfully met. These results formed the technical foundation of the Lac Knife Feasibility Study (updated 2023), which outlined a process plant designed to produce 50,000 tonnes per year of graphite concentrate, including 47,781 tonnes of high-grade 97.8% TGC salable concentrate from a feed grade of 14.8% TGC. The process flow sheet developed through this work includes crushing, grinding, polishing, flotation, concentrate dewatering and drying, concentrate screening and bagging, and tailings filtration and loadout. While the Feasibility Study demonstrated Lac Knife's ability to deliver ultra-high-purity graphite, subsequent market feedback confirmed that such high purities are not required - and do not command a price premium - in most anode or industrial applications.

As a benchmark, the U.S. Defense Logistics Agency ("DLA") Strategic Materials program has defined procurement specifications for natural graphite as -100 mesh concentrate. Lac Knife material comfortably exceeds U.S. defense-grade requirements, while simultaneously aligning with anode makers' specifications for EVs and stationary energy storage.

Coarse graphite flakes are rare and command premium pricing in markets where physical size is the key differentiator. On October 20, 2023, China announced its restrictions on certain graphite exports to the United States and other counties, with the new regulations taking effect on December 1, 2023. These rules, requiring export permits for high-grade natural and synthetic graphite products, were introduced under the banner of protecting China's national security. Most projects worldwide produce very little of this unique material. With its coarse flake profile, Lac Knife positions Focus to supply several high-margin speciality applications:

• Jumbo flake (+30, +25, +20 mesh; ~5% of total, up to 0.84 mm in size) - High-end EMI shielding in electronics and defense equipment, corrosion resistant gaskets in marine and aerospace, crucibles for specialty alloys and rare earth processing, radar absorbing and steal composites, icephobic for aircraft and ships, precursor for graphene platelets.

• +50 mesh (~15%) and +80 mesh (~24%) - Expandable and expanded graphite for fire-suppressant foams. With PFAS-based aqueous film-forming foams ("AFFF"), otherwise known as forever chemicals, being phased out amid billion-dollar lawsuits, demand for safe, graphite-based alternatives is expected to surge. Processed graphite generated from these flake sizes are also used in lead-acid and premium performance alkaline batteries.

• +100 mesh - Recently proven in a hypersonic rocket nozzle launch, this fraction is valued in aerospace, defense, semiconductor and advanced materials markets.

• -100 mesh - Tailored for the battery-grade anode market in both EVs and stationary battery energy storage systems ("BESS") applications, ensuring compliance with global demand.

Additionally, Lac Knife graphite demonstrates exceptionally low volatile content, a critical property for the most demanding nuclear and defense applications. While many companies can produce standard battery-grade graphite, nature rarely yields deposits with such a high proportion of coarse flakes. Lac Knife's increase in large and jumbo flake recovery from approximately 33% to 47% further strengthens Focus's strategic position. This advantage not only supports advanced processing pathways but also enables the Company to deliver environmentally friendly materials to market, creating opportunities to replace PFAS-based "forever chemicals" with safer, sustainable alternatives.

"The results from this pilot program reinforce Lac Knife's unique position as one of the few graphite projects capable of delivering both defense-grade and battery-grade material at scale," said Dean Hanisch, CEO of Focus Graphite. "By achieving market-aligned concentrate specifications, we are not only positioned to supply the EV and energy storage sectors, but also to serve premium aerospace, defense, and specialty markets. This dual-market advantage reduces risk, expands opportunity, and underscores Focus Graphite's role as a strategic supplier in North America's critical minerals supply chain."

It should be noted that this pilot program was conducted on more than 800 kilograms of Lac Knife graphite, and while the results are consistent with expectations, they may not fully represent the variability of the entire deposit. Focus intends to conduct larger scale testing in the future.
