Lithium: The Brine Boom and the Unsettled Rights of Mineral Owners

Part 1: What is Lithium and Why is it a Critical Mineral?

Lithium (chemical symbol Li) is a soft, silvery-white alkali metal. It is classified as a "critical mineral" by the U.S. government, meaning it is essential to national security and the economy.

• Value and Demand: Lithium’s primary value comes from its essential role in rechargeable batteries for electric vehicles (EVs), renewable energy storage systems, and electronics. Demand for the mineral is expected to grow significantly, with projections anticipating a 25–30% annual increase over the next decade.
• Extraction Innovation: Historically, lithium was extracted through hard rock mining or large evaporation ponds. A technological shift is underway with the focus moving to Direct Lithium Extraction (DLE). DLE is designed to extract lithium from deep subsurface brines or produced water that comes up alongside oil and gas. The process is noted for potentially offering a smaller surface footprint, lower carbon emissions, and less water usage compared to traditional methods.

Part 2: Where the Lithium is Found in the U.S.

The U.S. has significant domestic lithium resources, primarily found in deep underground formations and produced water. Major companies like ExxonMobil are investing heavily in this sector.

• Smackover Formation: This formation, which stretches across southern Arkansas and East Texas, is a key focus due to his high-grade lithium brine concentrations.
• Marcellus Shale: In states like Pennsylvania, produced water from natural gas operations also contains significant dissolved lithium, presenting another opportunity for extraction.

Part 3: What the Lithium Boom Means for Mineral Owners

The lithium boom offers new potential revenue streams, but it introduces significant legal and financial complexities, particularly in lease negotiations.

The Unsettled Ownership Question

The most complex issue is the legal ownership of lithium when it is dissolved in produced water or brine. Since oil and gas leases were generally drafted to focus only on hydrocarbons, they often did not specify ownership of other valuable minerals in the produced water. Ownership of this dissolved lithium is determined on a state-by-state basis.

• Texas Ambiguity: In Texas, state law provides that parties taking possession of produced water for beneficial use take title to that water. Unless a mineral owner's lease explicitly reserves the rights to lithium and other minerals, the operator may claim ownership of the valuable elements within that water. While lithium is clearly a mineral, its existence in brine complicates whether it belongs to the mineral estate or the surface estate.
• Arkansas Framework: Arkansas has a clearer statutory framework under its Brine Conservation Act. The Arkansas Oil and Gas Commission has set a 2.5% royalty rate for lithium extraction from brine.
• The ownership of the pore space and the minerals within are dependent upon state law. For extraction of lithium from saline aquifers, most states assign the lithium ownership to the surface owner. Ownership of Lithium extracted from produced water from the oil and gas stream is varied from state to state.

Royalty Rates and Compensation

Initial lithium royalty rates are often lower than those for traditional oil and gas, generally ranging from 2.5% to 10%. Mineral owners must negotiate diligently to secure favorable terms that reflect the mineral's full value.

Part 4: Recommendations for Mineral Owners

NARO strongly recommends the following steps to protect your interests and maximize potential benefits:

1. Consult with Experts: Always work with an attorney or mineral manager who specializes in complex mineral law and is familiar with lithium and brine extraction in your specific state.
2. Review and Draft Leases Carefully: Scrutinize any lease agreement to ensure it explicitly reserves your rights to lithium and other valuable minerals found in produced water. Avoid broad language that could transfer ownership without compensation.
3. Negotiate Competitively: Advocate for royalty rates and calculation methods that are competitive with, or similar to, those for traditional oil and gas resources.
4. Protect Surface Interests: Carefully review and negotiate clauses concerning surface use, as DLE infrastructure will be necessary for production.
5. Stay Informed: Continuously monitor legislative and regulatory developments (such as rule changes by the Texas Railroad Commission) and court decisions, as they are rapidly shaping the legal landscape for mineral ownership.
