Brunswick Exploration Outlines Significant New Lithium Potential in Tills at Anatacau West

Brunswick Exploration Outlines Significant New Lithium Potential in Tills at Anatacau West

Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; " BRW " or the " Company ") is pleased to report multiple high spodumene grain counts in till samples collected on the Anatacau West Property (the "project") which is the immediate extension of Arcadium's James Bay Lithium project. These highly encouraging results ( up to 1,225 spodumene grains in a single sample ) further reinforce lithium potential in the bedrock and delineate a new, highly prospective unexplored area at Anatacau West property (Figure 1) beyond the previously drilled pegmatites.

Spodumene Grain Count at Anatacau West

Mr. Killian Charles, President and CEO of BRW, commented: "Arcadium's James Bay Lithium project is one of the most exciting lithium projects in Quebec and today's results greatly expand the lithium potential we first outlined in drilling last year on our neighboring project. With the recent announcement of Rio Tinto's acquisition of Arcadium, the Anatacau West project is strategically positioned to benefit from any advancement at the James Bay Lithium project. Our work in 2023 was initially focused on the known showing on the western edge of the property where pegmatites found on Arcadium's claims continue onto the Anatacau West project. The major spodumene grain count anomalies found to the east of the drilled lithium showing potentially extend the pegmatite trends for several kilometers. Following these highly encouraging results, we will rapidly evaluate next steps at Anatacau West to test this highly prospective trend."

"I am particularly pleased to see Brunswick's exploration portfolio continue to demonstrate significant upside in one of the most exciting lithium districts globally. In the coming weeks, we expect more results from Mirage alongside further updates to our multiple exploration initiatives."

Anatacau West Till Program

During summer 2024, the Company conducted a widely spaced till sampling campaign on its Anatacau West project. Out of a total of 24 samples collected, four scattered samples returned very significant spodumene grains counts (1,226; 914; 47; 37) in the coarse sieved fraction in the

These high spodumene grain count till results demonstrate that an important mineralized trend extends further to the east on Brunswick's claims and that there is therefore a strong potential for new discoveries of near-surface spodumene dykes up-ice. With the new drone magnetic interpretation, we believe that the three holes drilled in 2023 to the east, which returned only anomalous lithium values, were located further north and outside of the main mineralized trend.

Currently Brunswick is resampling core from the 2023 drill campaign to evaluate the existence of lithium alteration halos in the adjacent host rock in the drilled area and the potential for new dykes immediately on strike and at depth to the existing pegmatites. This data will be incorporated into Brunswick's forthcoming plans at Anatacau West.

Anatacau West Project Overview

In 2023, Brunswick conducted a short drilling campaign (3,712 m) in the western portion of the property and near the boundary with the Arcadium claims. Several pegmatite dykes were identified by drilling with grades up to 26.5 m at 1.51% Li2O m; 18.2m at 1.33% Li2O; 25.1m at 1.00% Li2O and 18.2m at 1.37% li2O (see press release dated July 20, 2023 ). The various dykes are stacked, range from 5 to 30m in thickness and are oriented NNE dipping strongly at 70 degrees to the west similar to pegmatites defined on Arcadium's James Bay Lithium project.

The drilling campaign did not continue further east due to marshier ground reducing access to surface geological information. A drone magnetic survey was therefore undertaken by the Company in February 2024 and indicates that the known mineralized spodumene rich dykes at Anatacau West are contained within an ESE-oriented major deformation corridor which also host the neighboring Arcadium James Bay Lithium deposit (110.2 Mt @ 1.3% Li2O) located approximately 2.5km west of Brunswick claim boundary.

The Anatacau West Project comprises 13 claims located 2.5 kilometers east of the Trans-Taiga major Highway. The property is accessible yearlong and near the "Relais Routier Km 381" truck stop. Anatacau West is part of the large Anatacau property package which also includes the Anatacau Main project where the Anais showing was discovered in 2023, containing a total of 704 claims, representing 37,058 hectares (370 sq. km.) currently under option agreement with ODEV.

Quality control

Tills samples were collected in the C-horizon from hand-dug pits at depths up to 1 m. These samples are separated approximately 500 m apart. Each till sample (12-20 kg) was placed in a plastic bag and securely sealed with fibertape. The 10-kg samples were treated by Big Nugget Laboratories of Saint-Alexis-des-Monts, Québec, who proceeded with the spodumene grain count after concentration of a dense mineral fraction of approximately 300g. The quantities of grains mentioned in the text and shown in figures correspond to the obtained counts normalized to 10kg of processed till matrix (

The sampling procedures and the quality control related to the till surveys followed protocols developed by Brunswick, Inlandsis and ALS. Data interpretation was done by Remi Charbonneau from Inlandsis.

Altech Batteries Ltd  Breakthrough 55% Higher Energy Density Anodes

Altech Batteries Ltd Breakthrough 55% Higher Energy Density Anodes

Perth, Australia (ABN Newswire) - Altech Batteries Limited (ASX:ATC) (FRA:A3Y) (OTCMKTS:ALTHF) has achieved a remarkable milestone in its Silumina AnodesTM battery material technology. The Company is delighted to announce an average 55% surge in lithium battery anode energy capacity, marking a significant breakthrough.

Highlights

- Altech achieves 55% surge in energy capacity in Li-ion batteries

- Average energy retention capacity of approximately 500 mAh/g

- Stable battery with sound cycling performance

- Follows Altech previously cracking the "silicon barrier" by achieving 30% energy increase

- Dispersion challenges limited further improvements

- Persistent R&D has now resolved these challenges

- Altech aims to revolutionise the Lithium-ion battery industry

By utilising its innovative proprietary technology, Altech has now improved on the previous 30% energy increase, by blending alumina-coated silicon particles (10%) with battery-grade graphite, to create a composite graphite/silicon anode for the lithium-ion battery electrode. Upon activation, this composite material has now exhibited a remarkable 55% increase in capacity compared to the traditional graphite-only anode material, See Figure 1.

In a series of tests, the Altech lithium-ion battery anode material exhibited an average energy retention capacity of approximately 500 mAh/g, which is significantly higher than the average of approximately 320 mAh/g for a normal lithium-ion battery anode. This represents an average of 55% increase in energy retention capacity. Importantly, the Altech Batteries demonstrated good stability and cycling performance, indicating that the technology is highly promising. Altech's technology has the potential to be gamechanging and has demonstrated that silicon particles can be modified to resolve the capacity fading caused by both the swelling and first-cycle-capacity-loss problems. Altech's Research and Development team, led by Dr. Jingyuan Liu, achieved this significant breakthrough.

Altech had previously declared a major achievement in the field of battery technology. The Company reported that it had overcome the "silicon barrier" and had manufactured and evaluated a range of lithiumion battery anode materials that exhibit a retention capacity of approximately 30% higher than the standard lithium-ion battery anode materials. Following this breakthrough, Altech's research and development laboratory in Perth, Western Australia has been striving to further enhance the technology beyond this initial success.

As the Company endeavoured to surpass the 30% retention capacity achieved in the previous generation of batteries by increasing the silicon content, it encountered challenges in dispersing the alumina-coated silicon particles. However, Altech managed to overcome these challenges by implementing improvements in organic binders, coating parameters, and several other innovative solutions. After persistent efforts, the final challenges were eventually resolved, allowing the Company to move forward with the development of the next generation of batteries.

Through laboratory testing of the composite graphite/silicon batteries, Altech was able to substantially overcome previously unresolved impediments associated with using silicon in lithium-ion battery anodes.

These impediments include silicon particle swelling, first-cycle capacity loss of up to 50%, and rapid battery degradation. Altech's testing showed that the innovative composite graphite/silicon batteries were able to overcome these challenges, by spherification of the silicon particles. The spherical structure allows the distribution of alumina-coated silicon in graphite voids, hence minimises the electrode layer damaging due to expansion, see Figure 3, and 4. By doing so, via the alumina coating, the negative impact caused by the expansion of silicon is well managed in a lithium-ion battery.

The lithium-ion battery industry has recognised the introduction of silicon in battery anodes as a crucial step in achieving a significant increase in energy density, as well as reducing costs. This is because silicon has approximately ten times the energy retention capacity of graphite, making it an ideal anode material for the next generation of lithium-ion batteries. However, until now, the use of silicon in commercial lithium-ion batteries has been limited due to two critical drawbacks. Firstly, during battery charge, silicon particles expand by up to 300% in volume, leading to particle swelling, fracturing, and eventual battery failure.

Secondly, silicon deactivates a high percentage of the lithium ions in a battery, immediately reducing battery performance and lifespan. The industry has been in a race to overcome these obstacles and crack the silicon barrier to unlock the full potential of silicon in lithium-ion batteries.

The Company completed a Definitive Feasibility Study for the construction of an 8,000tpa Silumina AnodesTM plant in Saxony, Germany, that included the following economics.

- Pre-tax NPV10 EUR684 million

- Low capital cost of EUR112 million

- Attractive Internal Rate of Return of 34%

- EBITDA EUR105 million p.a.

- Payback (full rate) 2.4 years

- Revenue per annum of EUR328 million

Altech is in a race to get its patented technology to market. To support the development, Altech has constructed a pilot plant adjacent to the proposed project site to enable the qualification process for its Silumina AnodesTM product. The Company has successfully completed the construction of the pilot plant and is now in the process of hot commissioning.

CEO and MD Mr Iggy Tan stated "We are thrilled with the significant progress we have made in overcoming the critical challenges associated with using silicon in lithium-ion battery anodes. Our breakthrough technology represents a major step forward in unlocking the full potential of silicon in lithium-ion batteries, and we believe it has the potential to revolutionise the battery industry. We are currently commissioning a pilot plant to further scale up our technology and bring it to market".
