Lithium and Boron: The Nevada Clay Play for Battery Minerals

On October 14th and 15th, Albemarle (ALB) saw analysts split on its future. Mizuho upgraded Albemarle to Buy with a $130 target, citing surging energy storage demand. The same day, Baird cut its target to $123 from $157, and RBC reduced its target to $129 from $157. This divergence reflects a market trying to price the future of a dominant player in a rapidly evolving supply chain. The underlying tension is about where the next wave of critical minerals will come from, and how quickly it can be brought to market. The market for battery minerals, particularly lithium, is not just about brine operations in South America or hard rock mines in Australia anymore. North America, specifically Nevada, has become a focal point for clay-based lithium and boron projects. These deposits offer a different geological profile and extraction challenge, but promise domestic supply security. The shift in focus is clear: from global giants extracting high-grade brines to smaller players developing lower-grade, but strategically important, clay resources closer to end-users.

The Clay Extraction Mechanism

Extracting lithium and boron from clay deposits is a different beast than traditional brine or hard rock methods. Brine operations pump mineral-rich water to the surface, concentrating lithium through evaporation in vast ponds. Hard rock mining involves crushing and processing spodumene, a lithium-bearing mineral, through flotation and chemical conversion. Clay, however, presents a unique challenge: the lithium and boron are adsorbed onto clay particles, not free in a solution or locked within a crystalline structure. The core mechanism for clay extraction typically involves leaching. Crushed clay ore is mixed with a solvent, often sulfuric acid, to dissolve the lithium and boron minerals. This creates a pregnant leach solution (PLS). The PLS then undergoes a series of purification steps to remove impurities like iron and magnesium, followed by concentration and precipitation to recover lithium carbonate or hydroxide, and boric acid or borates. The difficulty lies in optimizing the leach chemistry to maximize recovery while minimizing acid consumption, and then efficiently separating the target minerals from a complex soup of dissolved contaminants. High-purity output from clay often requires more sophisticated and energy-intensive processing than brine, but it bypasses the long evaporation times and reliance on specific climates.

Companies Working in the Nevada Clay Sector

Several companies are active in the Nevada clay and critical minerals space, each with distinct approaches to resource development. ioneer Ltd (IONR), for example, is developing the Rhyolite Ridge Lithium-Boron Project in Esmeralda County, Nevada. This project is a significant clay-based deposit aiming to produce both lithium carbonate and boric acid. The dual-product nature of Rhyolite Ridge is a key differentiator, leveraging the co-occurrence of these two critical minerals in the same ore body. Standard Lithium Ltd. (SLI) is primarily focused on brine projects in Arkansas, but its broader strategy involves advanced extraction technologies that could be applied to diverse resources. While not directly a Nevada clay player, their work on direct lithium extraction (DLE) methods is relevant to efficient processing across different deposit types, including clays where DLE could reduce environmental footprint and accelerate production. Atlas Lithium Corporation (ATLX) holds lithium properties in Brazil, but the company's broader strategy in critical minerals includes exploration and development. Their recent news on advancing pre-assembly steps for their processing plant in Brazil highlights the focus on bringing projects to production. Critical Metals Corp. (CRML) is active in the rare earth elements space, particularly with projects like the Tanbreez project in Greenland. While not a Nevada lithium-boron play, their focus on securing domestic supply chains for critical minerals, including rare earths, mirrors the broader strategic imperative driving interest in Nevada's lithium and boron. NioCorp Developments Ltd. (NB) is developing the Elk Creek critical minerals project in Nebraska, targeting niobium, scandium, and titanium. Like CRML, NioCorp is focused on establishing North American supply for critical materials, a theme that extends to Nevada's lithium and boron efforts. American Battery Technology Company (ABAT) is focused on lithium-ion battery recycling and primary mineral extraction. Their proprietary processes for extracting lithium from Nevada clay resources, specifically their Tonopah Flats project, are central to their strategy. ABAT aims to integrate their recycling capabilities with domestic primary production, creating a circular economy for battery materials. USA Rare Earth, Inc. (USAR) is developing the Round Top heavy rare earth and critical minerals project in West Texas, which also contains lithium and other high-value elements. While geographically distinct, their focus on a multi-mineral project with a complex processing flowsheet aligns with the challenges and opportunities presented by Nevada's clay deposits.

American Lithium Minerals, Inc.

American Lithium Minerals, Inc. (AMLM) operates as an exploration stage company, focusing on lithium and boron properties in Central Nevada. The company trades over the counter and files with the SEC under CIK 1356371. AMLM's primary asset is the Sarcobatus Lithium property, which consists of 1,780 acres of mining claims located in Central Nevada. This area is known for its clay-hosted lithium potential. AMLM was incorporated in Nevada in March 2005. Its activities since 2009 have focused on lithium exploration at Sarcobatus. The company has also previously acquired and divested cobalt, nickel, and graphite prospects in Central Nevada, and rare earth elements projects in Arizona and Illinois. The public record does not yet establish a measured or indicated resource for the Sarcobatus project. AMLM intends to expand its exploration and acquisition for mineral properties globally. The company also states an interest in developing Real World Asset Tokens to provide capital for mining operations, aiming to merge public markets with blockchain technology for asset liquidity. In February 2026, the SEC qualified a Regulation A offering for AMLM, covering up to 80,000,000 units, with up to 120,000,000 shares issuable if warrants are fully exercised. Each unit includes one share of common stock and a warrant to purchase 1.5 shares of common stock at an exercise price of $0.05 per share, expiring December 31, 2028. The minimum purchase requirement for investors is $1,000, though this can be waived.

What to watch

Several key developments will shape the trajectory of Nevada's clay-based lithium and boron sector. For ioneer Ltd (IONR), watch for updates on the permitting process for the Rhyolite Ridge project, specifically the Record of Decision from the Bureau of Land Management. Any news regarding project financing or definitive offtake agreements for either lithium or boric acid will be significant. For American Battery Technology Company (ABAT), monitor progress on their Tonopah Flats project, including pilot plant results and any announcements regarding commercial scale-up or partnerships with battery manufacturers. For American Lithium Minerals, Inc. (AMLM), look for announcements detailing exploration results, such as drill assays or resource estimates, from the Sarcobatus Lithium property. Further updates on their Regulation A offering and any capital deployment plans will also be relevant. Across the sector, keep an eye on regulatory developments in Nevada concerning water rights and environmental impact assessments for clay mining operations, as these can significantly influence project timelines and costs., { "label": "Mining & Crushing", "note": "Excavate and reduce ore size" }, { "label": "Leaching", "note": "Acid solvent dissolves target minerals into solution" }, { "label": "Purification", "note": "Remove impurities from pregnant leach solution" }, { "label": "Precipitation", "note": "Recover lithium carbonate/hydroxide & boric acid" }, { "label": "Battery/Storage", "note": "High-purity minerals feed energy storage manufacturing" } ], "highlight": 3, "highlight_note": "Efficient separation of target minerals from complex solution determines economic viability.", "footnote": "Source: Company filings, industry reports" }
