The Articles section of Unhinged Geology features insights and commentary on mineral exploration, geology, and resource development. Drawing from real-world field experience and ongoing exploration work, these articles explore topics such as lithium basin geology, geophysical surveys, drilling programs, and emerging mineral districts.
Our goal is to provide clear, practical perspectives on how exploration projects are developed—from early geological concepts to drill targeting and resource evaluation. Whether you are an industry professional, investor, or someone interested in the science behind mineral discovery, these articles offer a deeper look into the methods and thinking that drive modern exploration.

What Is a Mining Royalty—and How Much Is Too Much?
This article explains mining royalties, including NSR, GSR, and NPI, and shows how royalty burden impacts project economics. Using a real-world Nevada case study, we quantify how royalties affect NPV, profitability, and long-term value—demonstrating how even small percentages can result in billions in lost value
No Deposit Is a One-Mineral Deposit Anymore
Modern mineral deposits rarely contain just one commodity. From silver projects reporting AgEq grades to lithium deposits paired with boron and potassium, exploration geologists increasingly evaluate ore bodies as multi-metal systems where the combined value of several elements determines a project’s true economic potential.
Central Nevada’s Emerging Tonopah Lithium Belt
Central Nevada is emerging as one of the most active regions for lithium exploration in the United States. This article examines the developing Tonopah Lithium Belt, a corridor of lithium projects surrounding Tonopah, Nevada, and explains the geological processes, basin structures, and exploration factors driving new lithium discoveries in the region.
Lithium Brine Deposits: How Lithium Is Concentrated in Salt Lakes
Lithium brine deposits are one of the world’s most important sources of lithium. This article explains how lithium-rich groundwater accumulates in closed desert basins, how evaporation concentrates lithium in brines, and how these deposits are explored and extracted to supply lithium for batteries and energy storage.re
10 Field Signs an Ancient Drainage May Contain Gold
In many parts of the western United States, particularly in arid regions such as Nevada, placer gold is often found in ancient drainage systems rather than modern streams. These abandoned channels, known as paleochannels, once carried flowing water that eroded gold from mineralized bedrock and concentrated it within gravel deposits.
Why Nevada Is Becoming the Center of U.S. Lithium Production
Nevada has emerged as the center of U.S. lithium exploration and development due to its unique Basin and Range geology, lithium-rich claystone basins, and mining-friendly environment. This article explains how volcanic activity, closed basin systems, and major projects such as Thacker Pass, Rhyolite Ridge, and Clayton Valley have positioned Nevada as a key hub for future lithium production.
How Clay-Hosted Lithium Deposits Form
Clay-hosted lithium deposits form in tectonically active, internally drained basins where volcanic material is weathered, transported, and ultimately concentrated within fine-grained lake sediments. Over time, lithium becomes incorporated into clay minerals through chemical processes linked to evaporation, sedimentation, and diagenesis.
While surface intercepts and assay values often draw attention, the true scale of a clay-hosted lithium system is governed by basin architecture — fault geometry, subsidence history, and stratigraphic continuity. Understanding the structural framework of a basin is often more important than any single drill hole.
This briefing examines how these systems form and why architecture, not isolated assays, determines exploration success.
The Importance of Detailed Geological Mapping in Mineral Exploration
Detailed geological mapping remains one of the most important tools in mineral exploration. By documenting rock units, structures, and alteration patterns, geologists can identify controls on mineralization, refine drill targets, and build reliable geological models. Modern tools such as drones, tablets, and GIS are now transforming how field mapping is conducted.
