We detail a highly cost-effective structural modeling approach that employs remote sensing and experimental 3D modeling of elastic and plastic deformation (Valls, 2024a, 2024b, 2024c, 2024d) to define the specific volumetric target areas in your license where mineralizing fluids concentrate, efficiently allowing you to concentrate your exploration dollars by reducing prospective ground by 50% to 75% (Valls, 2024a, 2024b, 2024d). The predictive discovery of mineral and energy resources relies on rigorously defining the structural geology and tectonic framework of the depositional setting. For instance, kimberlites—which are the deepest mantle-derived melts reaching the Earth's surface and the primary host of diamonds—rely heavily on deep-rooted faults and crustal structures to define their fluid flow pathways and favorable emplacement geometry. Similarly, in rifted lacustrine basins like the Bohai Bay Basin, fault zones are the controlling mechanism for hydrocarbon accumulation, requiring detailed structural geological modeling utilizing seismic data to assess trap integrity and fluid pathways. In metallic ore systems, disseminated gold (Carlin-type) and polymetallic Co-Cu-Au deposits in metasedimentary rocks (Blackbird, Kuusamo belt) are typically structurally controlled, clustering along major shear zones, folds, and breccia zones associated with deep-crustal discontinuities. Crucially for validation, structural analysis defines the timing of deformation relative to fluid flow; a structure must be active (e.g., dilating) during the mineralizing fluid pulse to be considered the primary control on localization. Our proven technique starts with mapping geological lineaments from satellite images and Digital Elevation Models, integrating this data through correlation analysis into a single prospective map. This unique process employs physical analogs, such as utilizing gelatin for elastic modeling and sand for plastic deformation modeling, to identify deep-seated dilatant zones (Valls, 2024a, 2024c, 2024d)—the necessary "space or volume" required for a deposit to form below the surface. We also discuss the potential link between Co-Cu-Au deposits and the major, structurally focused Iron Oxide Copper-Gold (IOCG) deposits. Understanding these structural controls is vital for any structural geologist, ore prospector, or student engaged in modern predictive resource assessment and is supported by detailed geophysical methods like magnetic and electromagnetic surveys.
