Brunswick Exploration Launches Canada-Wide Prospecting Programs and Stakes Additional Ground

Brunswick Exploration Launches Canada-Wide Prospecting Programs and Stakes Additional Ground

Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; " BRW " or the " Company ") is pleased to announce that it has started prospecting campaigns in Ontario and Saskatchewan with helicopter-supported prospecting in Manitoba and Quebec to begin in early June. Additionally, BRW has staked additional claims in Ontario, Manitoba and Saskatchewan targeting newly identified, untested S-type pegmatites.

Mr. Killian Charles, President and CEO of BRW, commented: "We are very excited to start one of the largest grassroot lithium exploration initiatives in North America. Over the last 18 months, we have diligently built our hard-rock portfolio focused on both poorly explored lithium-bearing pegmatites and untested, prospective pegmatite targets in favorable jurisdictions. We have now secured over 650 S-type pegmatites across all of Canada that have never been tested for lithium, in addition to nearly a dozen spodumene-bearing pegmatites.

"Concurrent with our pan-Canadian prospecting initiative, we are preparing our next drill campaign at Hanson Lake, Saskatchewan, which is anticipated to start in Q3. Furthermore, we continue to advance drilling at Hearst with preliminary results expected in early June. We are very optimistic that Canada hosts multiple world-class lithium deposits that are yet to be discovered and are confident that BRW can bring some of these deposits to fruition."

Quebec: Eeyou Istchee-James Bay

Starting in June, BRW will begin a major helicopter-supported prospecting campaign from two central camps: the Wabamisk camp, near the Anatacau and Anatacau West projects, and the PLEX camp, located near the PLEX and Mythril projects. A smaller fly camp, will also be set-up near the Mirage project, located further east from the PLEX project. The Company's portfolio in the entire Eeyou Istchee-James Bay region includes over 250 untested S-type pegmatites measuring a minimum strike length of 500 metres.

  • Anatacau: BRW will follow up on the newly intercepted spodumene bearing pegmatites from the recent drill program at Anatacau West. The pegmatites are hosted in an east-west deformation corridor and the entire trend is highly prospective. Further east, on the Main Anatacau claim block, the Company has already identified several spodumene showings which will be targeted for extensive prospecting.
  • PLEX and Mythril: BRW will prioritize prospecting pegmatite targets identified on the PLEX and Mythril projects. On Mythril, several untested pegmatite outcrops lie near the shared claim border with Patriot Battery Metals and are located less than two kilometres north of the CV8 spodumene showing. Prospecting will also be launched on the larger PLEX project, with over 120 untested pegmatite outcrops have been identified through compilation. All targets are hosted within the La Grande Shear Zone, which is also host to all known spodumene-bearing pegmatites on Patriot Battery Metals' land package.
  • Mirage: Prospecting will initially focus on confirming the occurrence of several large, angular spodumene-bearing boulders reported from the property. The shape and size of the boulders indicate a proximal source and multiple prospective pegmatite outcrops have been identified from satellite imagery up-ice from the boulders. BRW will also concentrate its efforts on multiple historical lithogeochemical anomalies that were identified in altered basalts (over 100 ppm lithium; Quebec government SIGEOM database). These anomalies suggest local alteration from an influx of lithium-bearing fluids

Following the prospecting campaigns, results may warrant drilling and stripping programs in H2/2023.

Saskatchewan

Crews are currently prospecting at the Hanson Lake pegmatite field to prepare for a drill program in Q3. The Hanson Lake pegmatite field, located next to existing paved road infrastructure, is an eight kilometer by three kilometer corridor that is part of the larger Jan Lake granite-pegmatite suite where the company has secured over 55 large-scale pegmatites. Following prospecting at Hanson Lake, crews will continue truck and boat-supported prospecting on other BRW claim holdings. Helicopter-supported prospecting will initially begin in the Reindeer Lake area in early Q3.

The Company has also staked an additional 48,000 hectares within the Trans-Hudson and Lake Athabasca Projects. These claims were staked based on excellent outcrop exposure, preferred geological environments, geochemistry and historically mapped and interpreted pegmatites. This additional ground includes over 45 pegmatites between 500 and 11,500 meters that have not been assessed for lithium. In Saskatchewan alone, the company has now secured over 225 S-type pegmatites that have a minimum strike length of 500 meters.

Ontario

The company has staked over 10,900 hectares with favorable outcrop exposure and forestry road access roughly 70 kilometers north of Kenora, known as the Campfire project. This package was compiled based on preferred geological environments and historical lake sediment data. The Campfire Project is within the English River Belt which hosts the Tanco mine (Canada's only producing lithium mine) and is roughly 25 kilometers east of the Separation Rapids lithium deposit.

Prospecting in Ontario will begin in Hearst in May before moving to the Campfire Project following the completion of prospecting in Manitoba and Saskatchewan. As new forestry roads and logged areas are planned for 2023, BRW expects to benefit from greater access and outcrop exposure throughout the Hearst Project as the project remains poorly explored.

Manitoba

BRW will begin prospecting at the Lynn Lake project in early June. The entire Lynn Lake region has never been explored for lithium. With excellent outcrop exposure, helicopter-supported prospecting is expected to be very efficient.

The company has also staked an additional 38,000 hectares throughout the Trans-Hudson belt of Manitoba based on geological environments, historical geochemistry as well as mapped and interpreted pegmatites. Of these newly acquired pegmatites, twelve are between 500 and 6,000 metres of exposed strike length.

Altech Batteries Ltd CERENERGY Battery Prototype Reaches Key Milestones

Perth, Australia (ABN Newswire) - Altech Batteries Limited (ASX:ATC,OTC:ALTHF) (FRA:A3Y) (OTCMKTS:ALTHF) is pleased to announce the latest performance results of the CERENERGY(R) cell and battery pack prototypes. These results confirm the technological maturity and robustness of the CERENERGY(R) technology and mark another decisive step towards industrialisation.

Highlights

- 650+ cycles with no capacity loss, proving exceptional material stability and long operational lifespan compared to conventional batteries

- Near 100% Coulombic efficiency, confirming minimal side reactions and strong intrinsic safety of sodium nickel chloride chemistry

- High energy efficiency of up to 92%, surpassing typical 70-80% levels of competing battery technologies

- Proven safety under extreme conditions - cells remained stable during overcharge, deep discharge, and thermal cycling up to 300 degC with no gassing, leakage, or rupture

- Robust and reliable chemistry - sodium nickel chloride avoids flammable electrolytes and runaway risks, confirming suitability for safe, large-scale grid and renewable energy storage

- ABS60 prototype validated under real-world conditions -tested across diverse load profiles, high-current pulses up to 50 A, and thermal variations

- Stable, efficient performance - achieved ~88% round-trip efficiency with no observable capacity fade over 110+ cycles

CELL PERFORMANCE

The CERENERGY(R) prototype cells have successfully completed over 650 charge-discharge cycles without any detectable capacity loss. Cycle life is a critical measure of battery durability, as most conventional batteries experience gradual degradation with every cycle. Achieving such performance highlights the outstanding stability of the materials and points to the potential for a long operational lifespan.

For stationary energy storage systems (ESS), this translates into fewer battery replacements, lower lifetime operating costs, and greater reliability for end users.

The cells also delivered nearly 100% Coulombic efficiency alongside an energy efficiency of up to 92% across 650 cycles. Coulombic efficiency reflects the proportion of charge recovered during discharge relative to what was supplied during charging. A value approaching 100% indicates minimal side reactions or parasitic losses, confirming the intrinsic stability and safety of sodium nickel chloride chemistry. This high efficiency demonstrates that the cells are not expending energy on unwanted processes such as electrode degradation. Such performance is vital for scalability, ensuring reliable, longterm operation in commercial energy storage applications.

Energy efficiency represents the proportion of energy delivered relative to the energy supplied. Competing technologies, including conventional high-temperature batteries and many flow batteries, typically achieve only around 70-80%. By reaching 92%, CERENERGY(R) positions itself in a highly competitive class, offering more cost-effective energy storage, stronger economics for grid operators, and seamless compatibility with the requirements of renewable energy integration.

The cells achieved a nominal capacity of 100 Ah and 250 Wh, with reliable performance even at higher discharge rates. A key feature is their ability to support multiple daily charge-discharge cycles within the 20-80% state of charge (SoC) range at 25 A. This capability positions CERENERGY(R) as a highly flexible solution for grid operators and energy storage providers, enabling cost-efficient, long-life performance in applications that demand frequent cycling such as renewable integration, peak shaving, and backup power.

CERENERGY(R) prototype cells underwent rigorous abuse testing, including overcharge to 4 V, deep discharge to 0.2 V, and thermal cycling between room temperature and 300 degC. In all cases, the cells remained stable with no gassing, leakage, or rupture -clear proof of their outstanding safety. These results highlight the intrinsic stability of sodium nickel chloride chemistry, which avoids the flammable electrolytes and runaway risks common in lithium-ion batteries. The ability to withstand extreme electrical and thermal stress demonstrates CERENERGY(R)'s robustness and confirms its suitability for safe, largescale deployment in grid, renewable, and industrial energy storage applications. This was achieved over 3 cycles with 1.8 Full Charge Equivalent (FCE) into 22 hours.

BATTERY PACK ABS60 (60 kWh) PROTOTYPE

The first ABS60 battery pack prototype has been successfully validated under real-world operating conditions, marking a major step forward in product readiness. Testing included diverse load profiles,

continuous discharges at 25 A (equivalent to C-rate of C/4 (discharges in 4 hours), or one-quarter of the pack's rated capacity per hour) at 80% depth of discharge (DoD), short-duration high-current pulses up to 50 A, and carefully controlled thermal variations.

The pack consistently demonstrated stable performance, achieving ~88% round-trip efficiency while maintaining reliable thermal management. Efficiency refers to the proportion of input energy that can be retrieved during operation-a critical measure of economic viability for large-scale storage. Over more than 110 cycles, results showed no observable capacity fading and only a slight increase in internal resistance. Capacity fading refers to the gradual decline in usable energy over repeated cycles, while internal resistance influences power delivery and heat generation.

The absence of meaningful degradation confirms the durability and electrochemical stability of the ABS60 design. These outcomes are highly significant as they demonstrate that the pack can withstand real-world duty cycles while retaining performance and efficiency, translating into longer service life, fewer replacements, and lower total cost of ownership.

For grid operators and renewable integration projects, this combination of robust cycling capability, efficiency, and thermal stability underscores the ABS60's commercial readiness and competitive advantage in the stationary energy storage market.

These results are a strong confirmation of CERENERGY(R)'s technological leadership and a clear signal of the technology's competitiveness and robustness for future applications in energy storage and industrial markets.

Group Managing Director, Iggy Tan said "These results confirm CERENERGY(R)'s robustness and readiness for market adoption. Demonstrating long cycle life, high efficiency, and unmatched safety, we are now strongly positioned to deliver a competitive and sustainable alternative for grid and industrial energy storage."
