Most metallic mineral deposits form at places where there is a specific geological architecture, and a special set of geological interactions between fluids, magmas, faults and rocks. Because we all consume metals all the time, society demands that we explore to find more. Discovering new mineral resources is increasingly difficult. Much of the land surface has been well-explored, is covered with glacial till, or is off limits to mining activites. Therefore, mineral exploration must increasingly consider the type of geological architecture and locations of past geological interactions deeper and deeper in the crust.
Various geophysical methods, likes the ones included in CCarray, provide researchers with an unparalleled opportunity to ‘see’ into the crust to identify those geological features like deep faults that may be responsible for bringing metal-bearing magmas and fluids to the near-surface. We can look backwards by evaluating features beneath existing mineral deposits, and look forward by considering locations where as yet undiscovered resources may occur.
