CYPRESS DEVELOPMENT ANNOUNCES DRILL RESULTS FROM CLAYTON VALLEY LITHIUM PROJECT, NEVADA

TSXV: CYP | OTCQX: CYDVF

Cypress Development Corp. (TSXV: CYP) (OTCQX: CYDVF) (Frankfurt: C1Z1) ("Cypress" or "the Company") is pleased to report results from the recently completed drill program at its 100%-owned Clayton Valley Lithium Project ("Project"), in Nevada, USA . A sonic drill program was conducted in May 2022 to obtain sample material for lithium extraction testing at the Company's Lithium Extraction Facility ("Pilot Plant") in Amargosa Valley, Nevada and to supplement the Project's resource model for the Feasibility Study that is currently underway.

Highlights:
  • Best intersection of 70.1 meters of 1,336 parts per million ("ppm") lithium
  • Successful use of sonic drilling to obtain six- and four-inch diameter cores
  • Completed 580 meters in eight drill holes ranging from 61 to 76 meters in depth
  • Acquired 15 tonnes of claystone for testing at the Company's Pilot Plant
  • Confirmed resource model built by Global Resource Engineering ("GRE")
  • Confirmed drill data obtained in the acquisition of Enertopia Corporation ("Enertopia") property

"The drill program was highly successful in generating material for our pilot plant and providing distinct data to strengthen the Project's resource model" stated Bill Willoughby , Cypress President, and CEO. "These are significant steps as we continue to work to de-risk the project and provide information for the Feasibility Study."

Drill Program

Cypress has received all assays from its May 2022 drilling program. The program was conducted to collect claystone with large diameter core for use in metallurgical testing at the Company's Pilot Plant. A total of 580 meters were drilled in eight holes. Hole depths were limited to intersect lithium-bearing claystone to a depth of 61 to 76 meters and to obtain approximately 15 tonnes of material for testing.

Representative core samples ranging from 0.1- to 3-meters in length were collected and delivered to ALS Global in Reno, Nevada for analysis. Lithium values shown in the table are weighted averages over the length of claystone intersected in each hole. All eight holes ended in lithium-bearing claystone. Each sample submittal was accompanied with QA/QC samples of blanks, standards, and duplicates.

Measurements from surface, samples analysed with four acid digestion with ICP-MS

Four holes, CSV1 through CVS4, were drilled in the central portion of the Project in the vicinity of the planned starter-pit. CVS2 is located outside of the reserve pit outline from the 2021 Prefeasibility Study, nearest the location of the anticipated plant site for the feasibility study. CVS3 is located adjacent to a reclaimed test pit where 500-tonnes of claystone were collected in April.

Four additional holes, CVS5 through CVS8, were drilled in the northeast portion of the project on and near the parcel of property acquired this year from Enertopia. These holes were arranged southeast to northwest infilling the fence of TOP-01, TOP-02, TOP2M and TOP-04 drilled by Enertopia, and DCH-09 drilled by Cypress.

Interpretation of Results

The assay results are in line with lithium grades predicted at all eight locations by the resource block model developed by GRE. The overall estimated lithium grade for all eight locations from GRE's model is 1,060 ppm. This compares to the compiled average lithium grade from all eight holes drilled of 1,080 ppm, for a variance of +2%.

When viewed in cross-section, the assay results are also consistent with those from previous drilling and support the continuation of a higher-grade northeast trend of lithium-bearing claystone on Cypress's project as interpreted by GRE in developing the resource model. The results are encouraging and have potential to extend the 2021 pit design through Cypress hole DCH-13 (82.3 meters, 1,221 ppm lithium) to CVS6, CVS7 and the northeast corner of the property.

With the drill program completed, GRE will revise and update the resource model with the new data and proceed with work on the mine plan and production schedule for the feasibility study, which is expected to be completed by year end.

Altech Batteries Ltd  CERENERGY Battery Prototype Reaches Key Milestones

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."
