Clayton Valley Deep Basin Lithium Brine Project

Sienna Resource’s 1,200-acre “Clayton Valley Deep Basin Lithium Brine Project” is located directly inside of, and completely surrounded by Pure Energy Minerals Ltd’s (PE-TSX.v) property. The “Clayton Valley Deep Basin Lithium Brine Project” is located in parts of the deepest sections (refer to the map) of the only lithium brine basin with a producing operation in North America, Albemarle Corp’s (NYSE: ALB) Silver Peak Mine. Pure Energy Minerals, which owns the Clayton Valley South project, has  released an inferred resource of 247,000 tons of lithium carbonate equivalent on the Clayton Valley South project. According to the Pure Energy Minerals Limited website, “Geophysics shows that the same brine-bearing formations encountered during drilling (Pure) appear to extend to much greater depths within the basin.”

On Tesla Battery Day, held on September 22, 2020, Tesla’s Elon Musk announced their intention to acquire Nevada lithium projects and their overwhelming need to secure domestic lithium deposits to feed their Gigafactory.

Jason Gigliotti, president of Sienna Resources, stated: “We would like to congratulate the SLB and Pure teams for many years of hard work finally coming to fruition. This is a watershed moment for the Clayton Valley itself as this marks the true entrance of SLB into the lithium space. Sienna has been holding its Clayton Valley Deep basin lithium projects for many years watching the developments on this project, primarily as Sienna shares the deepest part of this basin with SLB. SLB still has a road ahead, but this moment is clearly a turning point for development within this basin. We look forward to now moving this project much higher up in the Sienna project priority list.”

On March 18, 2021, Schlumberger New Energy Venture (NYSE: SLB) announced the development of a lithium extraction pilot plant with a strategic partnership with Pure Energy (TSX.v: PE). 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 Sienna is located in the deepest section of this brine deposit.
