Feb 15, 2021· If an ore deposit is variable in grade then a large number of drill-holes will be required to define the resource. For deposits with a consistent grade, much less drilling is needed. Gold deposits are usually variable in grade over short distances, so a large number of drill-holes are needed to define this type of resource.

The orientation of syn‐mineralisation far‐field stresses must also be inferred. Two examples of orogenic gold deposits, which meet the above criteria, are used to illustrate the potential of stress mapping in cross‐section. Sunrise Dam, located in the Archaean Yilgarn Craton, is a lode‐gold deposit sited in a thrust‐fold belt.

Fault zone hydrogeology is the study of how brittlely deformed rocks alter fluid flows in different lithological settings, such as clastic, igneous and carbonate rocks. Fluid movements, that can be quantified as permeability, can be facilitated or impeded due to the existence of a fault zone. This is because different mechanisms that deform rocks can alter porosity and permeability within a ...
