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.
