Clayton Valley Deep Basin Lithium Brine JV

About the project

On January 28, 2025, Adelayde Exploration announced that it has entered into a joint venture agreement (“JV”) with Sienna Resources Inc. (“Sienna”) and Cruz Battery Metals Corp. (“Cruz”) to explore the deep basin lithium brine potential in Clayton Valley, Nevada. The 115 mineral claims comprising the 2,300-acre JV land package are all located within, and completely surrounded by, SLB’s (formerly Schlumberger) (NYSE: SLB) lithium deposit. Clayton Valley, Nevada is home to the only long-established producing lithium brine basin in the U.S., Albemarle Corp’s (NYSE: ALB) Silver Peak lithium brine mine, which extracts lithium from subsurface brines. It has been the sole U.S. producing lithium brine operation since the 1960’s and is located in the direct vicinity of Tesla Motors Inc.’s (Nasdaq: TSLA) Gigafactory.

James Nelson, President of Adelayde stated, “Lithium prices are currently at 2-year highs and are now up well over 150% since June 2025, according to tradingeconomics.com. With the recent resurgence of investor attention back into the lithium sector, management feels this is an opportune time to explore the deep basin lithium brine potential within Clayton Valley, Nevada. The main reason the JV was formed was to create one large block in the center of the Clayton Valley lithium brine basin to formulate a drill program to test the deepest part with a shared cost and benefit to the JV participants. The Company is well financed to execute its planned exploration and work programs, and we look forward to a very active start to 2026.”

On March 18, 2021, Pure Energy’s strategic partner SLB’s Schlumberger New Energy Venture (NYSE: SLB) “announced the development of a lithium extraction pilot plant through its new venture, NeoLith Energy. The deployment of the pilot plant will be in Clayton Valley, Nevada, USA. The NeoLith Energy sustainable approach uses a differentiated direct lithium extraction (DLE) process to enable the production of high-purity, battery-grade lithium material while reducing the production time from over a year to weeks. This innovative process can create new market opportunities for lithium extraction and battery manufacturing economy and maximize the value of the lithium-rich resource base in Nevada with cutting-edge extraction technology.

On September 10, 2024 SLB announced that the ‘Nevada demonstration plant integrates direct lithium extraction (DLE), concentration and conversion technologies to sustainably produce lithium at scale with integrated technology solution produces lithium from brine 500 times faster than conventional methods while using significantly less land, water and chemical reagents with a verified results confirm recovery rate of 96% lithium from brine at operational rates. ‘  The success that SLB achieved could have a significant future impact on the brine prospects within Clayton Valley Nevada as Adelayde is located in the deepest section of this brine deposit.

Announced on September 11, 2024, Pure Energy Minerals Ltd.’s strategic partner, SLB has demonstrated completion of specific technical milestones to qualify the earn-in to 100-per-cent ownership of the CV project, which include continuous production of lithium carbonate for an extended period and achieving a material quantity of lithium product in excess of a required purity threshold, which was verified by a third party.
