Focus Graphite Signs LOI for High-
Performance Natural Graphite-Based RF
Shielding Technology
Independently tested at the University of the German Federal
Armed Forces in Munich, demonstrating up to 99.99% RF
signal blocking across defence-relevant frequencies
Ottawa, Ontario--(Newsfile Corp. - June 1, 2026) -
Focus Graphite Inc. (TSXV: FMS) (OTCQB:
FCSMF) (FSE: FKC0)
("
Focus
" or the "
Company
"), a Canadian developer of high-grade flake
graphite deposits and advanced graphite materials for battery, defence, and industrial applications, is
pleased to announce that it has entered into a non-binding Letter of Intent ("
LOI
") with PermaTint Ltd.
("
PermaTint
") (Shielding Solution) of Concord, Ontario, a developer and manufacturer of specialty
coatings, to evaluate the integration of the Company's graphite into the formulation through planned
validation testing, and to assess the potential acquisition or licensing of a proprietary radio frequency
("
RF
") shielding coating formulation (the "
Product
") containing graphite and demonstrating high-
performance signal blocking capabilities.
The Product, which contains natural flake graphite, has been independently tested by Shielding Solution,
a division of PermaTint, at the University of the German Federal Armed Forces in Munich (Universitat
der Bundeswher Munchen) in accordance with internationally recognized standards (IEEE 299 and
ASTM D4935), which measure how effectively materials and systems block radio frequency signals.
Testing across frequencies ranging from 5 GHz to 40 GHz demonstrated shielding effectiveness of
approximately 36 dB to over 50 dB depending on coating thickness, corresponding to the ability to block
up to 99.99% of electromagnetic radiation.
Potential applications for RF shielding coatings include military and defence infrastructure, aerospace
systems, secure communications environments, data centers, and protection of sensitive electronics
from electromagnetic interference and signal intrusion. These applications are becoming critical as next-
generation communications, electronic protection systems, and high-frequency technologies rapidly
expand across defence and advanced technology sectors.
Additional testing across lower frequency bands (100 MHz to 8 GHz) confirmed consistent shielding
performance across commercial and defence-relevant communication ranges, including 5G and
wireless systems.
The Company intends to conduct validation testing using its own graphite material, with planned third-
party testing to ensure direct comparability of results and accelerate potential commercialization efforts.
This initiative builds on Focus' advancing downstream processing capabilities, with graphite ore from
the Lac Knife Project nearing completion at SGS Canada Inc ("
SGS
") in Lakefield, Ontario (see news
release dated March 2, 2026). The Company expects to have approximately 750-800kg of high-quality
graphite concentrates, which will then be purified and upgraded for qualification and testing across
multiple advanced material applications, including RF shielding.
The LOI outlines a framework under which Focus may acquire full intellectual property rights to the
formulation or enter into a licensing arrangement to manufacture and commercialize the product, while
maintaining flexibility to pursue partnerships with third parties to support scale and market adoption, with
final terms subject to definitive agreement and completion of due diligence.
"Control of the electromagnetic spectrum is fundamental to modern military operations," said Wayne
Eyre, General (Ret'd), Advisor to Focus Graphite. "Technologies that can reliably block and manage
electromagnetic signals are critical to protecting communications, infrastructure, and personnel. Pairing
that capability with secure, allied graphite supply directly supports defence readiness and long-term
resilience."
"Graphite grade is the ultimate gatekeeper to high-value markets," said Dean Hanisch, Chief Executive
Officer of Focus Graphite. "North American producers cannot compete with adversarial supply on cost of
capital or low-cost labour; we must lead on performance. Our unusually high-grade material is the key to
unlocking premium, specialized downstream sectors like defence-grade RF shielding, where margins
and performance requirements are high. As we finalize our concentrate work at SGS, this RF shielding
formulation provides a clear, high-potential pathway to accelerate our downstream commercialization
strategy."
As governments and industry move to secure critical material supply chains, Focus continues to advance
its strategy to supply high-performance graphite and downstream solutions aligned with G7 and allied
priorities.
The Company continues to engage with partners across multiple sectors and welcomes collaboration
opportunities related to graphite supply, thermal purification, and advanced materials development
across defence, energy storage, and industrial applications.
