New Testing Confirms Highly Efficient Lithium Extraction Method for Electric Vehicles
Vancouver, Tuesday, 9 June 2026.
International Battery Metals achieved a major clean energy milestone, proving its extraction method recovers 98% of lithium and sustains over 1,200 cycles without degradation across varied brine sources.
Validating Direct Lithium Extraction Technology
On June 8, 2026, International Battery Metals Ltd. (IBAT) announced highly successful lab testing results for its proprietary Direct Lithium Extraction (DLE) technology [1]. Utilizing naturally occurring oilfield brine samples sourced from multiple operators across the Smackover Formation in Texas and Arkansas, the company achieved a lithium recovery rate of approximately 98% alongside a contaminant rejection rate of roughly 99% [1]. For the electric vehicle industry, which relies heavily on high-purity lithium for battery manufacturing, minimizing impurities is a critical step in reducing refining costs and accelerating production timelines [GPT].
Building on Past Commercial Successes
The recent laboratory success in the Smackover Formation builds upon a significant operational milestone achieved by the company two years prior. In 2024, IBAT successfully deployed a commercial-scale modular DLE plant in Utah [1]. Unlike the recent tests on naturally occurring oilfield brine, the 2024 deployment utilized synthetic brine to stress-test the system under controlled conditions [1].
Broader Momentum in North American Critical Minerals
IBAT’s advancements coincide with a broader, industry-wide push to secure domestic supply chains for critical minerals across North America [GPT]. On the same day as IBAT’s announcement, June 8, 2026, Grid Metals Corp. released an exploration update for its Makwa nickel-copper-PGM-cobalt project in southeastern Manitoba [2]. Under a December 2024 Joint Venture Agreement, Teck Resources Limited has spent over $2 million as of May 31, 2026, toward a required cumulative exploration expenditure of $3.7 million due by May 31, 2027 [2]. Completing these expenditures, alongside an eventual $15.7 million in total work and $1.6 million in cash payments, will allow Teck to earn up to a 70% interest in the project [2].
