Rain City Resources Announces Receipt of Independent Validation of ACCELi Lithium Extraction Technology
Montrose Report Confirms High-Purity Lithium Recovery and Saleable By-products from Marcellus Shale Brine Calgary, Alberta--(Newsfile Corp. - July 10, 2025) - Rain City Resources (CSE: RAIN) ("Rain" or the "Company") announces that it has received the finalized independent assessment, delivered by Montrose Environmental Group ("Montrose"), confirming the operational and commercial viability of Avonlea Lithium Corporation's ("ALC") proprietary ACCELi (Advanced Chemical Cavitation Extraction of Lithium) process. Rain currently holds an option to acquire a 100% interest in ALC. The recent pilot plant tested lithium-rich brine recovered from hydraulic fracturing operations in the Marcellus Shale, and despite suboptimal conditions, the ACCELi process consistently delivered strong results, highlighting its scalability, modular design, and economic potential. (see news release, June 26, 2025.) Montrose Report Highlights: Lithium phosphate solids were successfully produced with a purity of 94.2%. The third and final batch run achieved a 69.3% lithium recovery rate, demonstrating significant process optimization. Average lithium concentration in source brine across the runs was 243 mg/L, confirming high-value feedstock potential. The system reliably extracted barium, strontium, magnesium, and calcium using selective precipitation chemistry. A secondary saleable product-industrial-grade calcium carbonate (>98% purity)-was also produced. The pilot confirmed that the ACCELi process performed as intended under real-world operating conditions. The technology's modular and scalable design is well-suited for commercial expansion in North America and beyond. A preliminary economic assessment supports the ACCELi process' commercial feasibility, based on favorable brine composition, volume, and market value of end-products. Commenting, M Shevalier of Montrose said, "The advantage of this DLE technology is that it does not rely on membranes or resins which can be easily poisoned by things like oil present in the brines." This demonstrates that ACCELi is better positioned than existing DLE methods, such as adsorption or membrane separation, to cope with the contaminants, such as oil or fine particles, commonly found in lithium brines in oil fields or in the salars of South America. A Water-Smart DLE Solution Montrose also underscored the ACCELi process' potential advantages in water-scarce regions, citing its ability to recover water from both process steam and treated brine. This positions Rain as a differentiated player in the Direct Lithium Extraction (DLE) landscape, particularly in arid zones such as the South American Salars. "Where scarce water resources demand DLE processes with minimal freshwater requirements, the ACCELi process stands out," said Benjamin Hill, CEO of Rain. "This validation from Montrose enables us to accelerate discussions in South America, while continuing to advance commercial opportunities at the Springville site in Pennsylvania." Looking Ahead Rain is now in active engagement with potential partners and stakeholders in South America and is progressing commercial negotiations with the owners of the Springville Kendra II facility.

'China Achieves Unthinkable Feat': This Bold Extraction of 99.9% Ultra-Pure Rubidium from Salt Lake Brine Stuns the World
IN A NUTSHELL 🔬 Chinese scientists have developed a method to extract 99.9% pure rubidium chloride from low-grade brine, marking a significant breakthrough. from low-grade brine, marking a significant breakthrough. 🇨🇳 This achievement reduces China's reliance on foreign imports, particularly from Canada, strengthening its strategic mineral supply chain . . 💡 The new process involves innovative techniques like ore washing , rubidium leaching, and solvent extraction, offering substantial cost savings. , rubidium leaching, and solvent extraction, offering substantial cost savings. 🌍 China's advancement in rubidium extraction underscores its commitment to technological innovation and industrial resilience amid global competition. In a groundbreaking development, Chinese scientists have unveiled a novel method for extracting ultra-pure rubidium chloride from brine containing trace amounts of the metal. This achievement is a significant milestone for China's critical minerals supply, potentially reducing the country's dependency on foreign imports. As the world's largest consumer of rubidium, China has been reliant on countries like Canada for the majority of its imports. The breakthrough, reported by the Qinghai Institute of Salt Lakes, showcases China's growing expertise in strategic mineral extraction, promising a more self-sufficient future in high-tech and defense applications. The Significance of 99.9% Pure Rubidium The Qinghai Institute of Salt Lakes (ISL), a division of the Chinese Academy of Sciences, announced this remarkable achievement. Researchers succeeded in producing rubidium chloride with an astounding 99.9% purity from potassium chloride material, which contained a mere 0.001% rubidium. Previously, this ultra-low concentration was deemed commercially unviable, but the new process has changed that perception entirely. Rubidium is a soft alkali metal with critical applications across multiple sectors. It plays a vital role in high-tech fields, including atomic clocks, perovskite solar cells, aerospace systems, and specialized glass. The importance of rubidium is underscored by its use in ultra-precise atomic clocks, which lose less than one second over 3.7 million years. Additionally, its applications extend to medical research, particularly in imaging tumor cells. Despite holding some of the world's largest rubidium reserves, China has faced challenges in domestic development, primarily because over 97% of its rubidium is locked in low-grade hard rock deposits that are difficult and costly to process. Only a small fraction of rubidium is found in more accessible forms, such as salt lake brine, predominantly in Qinghai province and Tibet. This breakthrough could mark a turning point in China's rubidium industry. 'Biggest Wind Turbine Ever': China Smashes All Records With This Colossal Machine—But a Hidden Flaw Threatens the Whole Project A First for China: Reducing Dependency In 2021, China imported over 19,500 tons of rubidium concentrate, with a dependency rate of 66.3% on external sources like Canada and Zimbabwe. The addition of rubidium to the United States' critical minerals list in 2022 heightened the geopolitical stakes surrounding mineral access. He Xinyu, in China Mining Magazine, emphasized the need for China to bolster resource security through technological innovation and diplomatic engagement. The ISL's electrochemical separation group addressed the scientific and engineering challenges of rubidium extraction. They developed a high-fidelity model to trace rubidium's distribution during potassium salt processing, identifying the reasons for rubidium's resistance to enrichment. This model not only optimizes rubidium concentration but also has potential applications in resource mapping and separation techniques. The integrated process devised by ISL encompasses ore washing, rubidium leaching, enrichment, solvent extraction, and purification. This system has been successfully tested using potassium chloride from Qinghai's Qarhan Salt Lake, one of China's largest inland salt lakes, consistently yielding 99.9% pure rubidium chloride from low-grade feedstock, which was previously considered unusable. 'China Leaves West in the Dust': Its Small Nuclear Reactor Leap Puts Beijing Years Ahead in the Future of Clean Energy Impact on Costs and Industrial Resilience Beyond its technological significance, this innovative process could result in substantial cost savings. A 2022 cost analysis by ISL scientist Gao Dandan's team found that rubidium chloride produced through this method could be manufactured at just one-third of its current market price. This economic advantage could strengthen China's industrial resilience amid growing global competition for strategic minerals. Supported by the National Natural Science Foundation, CAS, and Qinghai provincial authorities, this development signifies a crucial step in China's pursuit of self-reliance in strategic mineral resources. By enhancing its capacity to produce rubidium internally, China is better positioned to withstand external pressures and maintain its lead in high-tech sectors. This breakthrough not only underlines China's commitment to technological advancement but also its determination to secure essential resources. As the global demand for strategic minerals intensifies, China's innovative approach could set a precedent for other nations seeking to bolster their mineral independence.
