Bradda Head Signs MOU with Tyson Energy

Bradda Head Lithium and Tyfast Energy Sign MOU to Advance the Development of a Domestic US Lithium Supply Chain for Next-Generation LVO Battery Anodes

Bradda Head Lithium Limited, a United States-focused lithium exploration and development company, and Tyfast Energy Corp. ("Tyfast"), a developer of advanced battery materials for heavy-duty electrification, have signed a Memorandum of Understanding ("MOU") to explore a domestic US lithium supply pathway for Tyfast's proprietary lithium vanadium oxide ("LVO") anode material. The collaboration aims to leverage Bradda Head's wholly owned US lithium assets in Arizona and Nevada with Tyfast's downstream battery material qualification process, advancing a Made-in-USA supply chain for high-performance batteries targeting the most demanding industrial and defense applications.

The collaboration will evaluate battery-grade lithium sourced entirely from US-based projects for integration into Tyfast's LVO anode platform, supporting heavy-duty vehicle electrification across construction, mining, trucking, and defense. This also provides Bradda Head with a potential downstream pathway for its US lithium assets, supporting its strategy to advance toward production and participate in the domestic battery supply chain.

Highlights

• MOU signed to evaluate battery-grade lithium from Bradda Head's US projects for Tyfast's LVO anode
• Bradda Head to assess feedstock and processing pathways; Tyfast will lead material qualification, and performance testing
• Focus on heavy-duty sector (mining, construction, trucking, defense)
• Supports development of a fully domestic US battery materials supply chain

Ian Stalker, Executive Chair of Bradda Head Lithium said:

"We have always believed that the proximity of our US projects to end-users is our greatest competitive advantage. This agreement further builds on our credentials and strategy of developing US lithium for the US market.

This collaboration represents a potential pathway to connect our US lithium resources to advanced battery applications, positioning Bradda at the forefront of the USA lithium industry, with a view to working closely with the appropriate regulatory authorities in developing their lithium strategy to maximizing future potential US production for the US markets.

We look forward to providing further updates in due course re-enforcing our strategy to position Bradda Head as a future domestic supplier of battery-grade lithium."

GJ la O', CEO of Tyfast Energy commented:

"Lithium is the other half of the equation for our LVO anode. We have been building a vanadium supply chain from the ground up with US and Canadian partners, and it is the right time to do the same for lithium. Bradda Head has a differentiated portfolio of US lithium assets across deposit types that directly complements what we need as we scale. This MOU is about establishing the building blocks of a fully domestic, high-performance battery supply chain."

Why a US Lithium Supply Pathway Matters

The heavy-duty vehicle sector faces increasing pressure to electrify, yet adoption has been constrained by battery technology limitations: inadequate charging speed, limited cycle life, and poor cold-climate performance. At the same time, battery manufacturers and OEMs are under growing scrutiny around the geographic origin of critical materials. Addressing both the performance challenges and the need for a secure, domestic supply chain will be key to enabling broader adoption. This MOU represents an initial step toward aligning advanced battery technology with a domestic critical minerals supply chain.

What makes Bradda Head distinctive is both the scale and the variety of our US lithium resources. The company holds 100%-owned projects spanning three fundamentally different types of lithium deposit - sedimentary clay, hard rock, and brine - all located in Arizona and Nevada. That breadth matters: different deposit types produce lithium through different processes, giving Bradda Head multiple routes to battery-grade material and reducing its dependence on any single project or technology path. At the Basin Project in Arizona, an independent resource estimate has confirmed over 2.8 million tonnes of lithium carbonate equivalent - enough to supply battery-grade lithium at scale for years. The San Domingo hard-rock project, with over 100 drill holes completed, is advancing toward its own resource estimate. A third project, Whistlejacket, is being developed in partnership with Kennecott, one of the world's most experienced mining companies. Taken together, Bradda Head's portfolio represents one of the most geographically and technically diversified lithium pipelines in the United States - entirely on US soil, in established mining states, close to the infrastructure and industrial customers that need it most.

Collaboration Scope (MOU)

Under this MOU - which establishes a non-binding framework for technical collaboration - the Parties intend to: within 45 days after the Effective Date, the Parties intend (but are not obligated) to prepare and mutually agree in writing on an initial workplan describing, as applicable: (i) sample request and delivery timelines; (ii) testing protocols, data requirements, and indicative acceptance and qualification criteria; (iii) meeting and data-sharing cadence; and (iv) estimated resource requirements for any subsequent development phase. This will then be followed by agreement to (i) define target specifications and qualification criteria for battery-grade lithium materials from Bradda Head's US projects; (ii) conduct bench- and pilot-scale material testing to optimize lithium feed properties for use in Tyfast's LVO anode synthesis; and (iii) evaluate commercialization and deployment opportunities in mining, construction, trucking, and defense applications across the United States. Each party is responsible for their own costs under the arrangement.

Why Tyfast and Bradda Head Are Complementary

Tyfast's LVO anode is designed around the electrochemical properties of lithium at its most demanding - rapid charge acceptance, multi-thousand-cycle durability, and stable operation at temperatures where conventional lithium-ion cells underperform. Lithium is a core feedstock in LVO anode active material production and sourcing it domestically at battery-grade purity is a prerequisite for a truly localized US supply chain. Tyfast has received Federal funding from the US Army, Defense Logistics Agency, US Air Force, National Science Foundation, Advanced Research Projects Agency - Energy and Department of Energy to develop and demonstrate its LVO technology - a track record that underscores the technology's relevance to demanding industrial and national security applications.

Bradda Head brings a unique exposure across multiple lithium deposit types in established US mining jurisdictions, with projects located in close proximity to infrastructure and end-user markets. Together, the Parties see an opportunity to build an upstream-to-downstream battery materials pathway grounded entirely in the United States.

Tyfast's reports that, based on internal testing, its LVO anode platform is designed to deliver the performance attributes most critical for heavy-duty electrification:

• Up to 10X faster charging than conventional lithium-ion batteries, enabling diesel-comparable equipment uptime
• Up to 10X longer cycle life, exceeding 10,000 full-depth discharge cycles
• Proven fast-charge capability at extreme cold temperatures, including down to -40°C
• Enhanced safety profile relative to traditional graphite anodes
• Energy density sufficient for extended operating range in high-demand commercial applications

Strategic Significance

The Parties believe this collaboration aligns with US federal priorities on critical minerals supply chain resilience, advanced manufacturing investment, and industrial decarbonization including alignment with IRA and DOE initiatives. Establishing a direct pathway from domestically mined and processed lithium to a novel, high-performance anode could contribute meaningfully to the emerging US battery value chain - one in which raw material origin, processing location, and end-use application are all anchored within the country.
