Orientation
A recipe for shrinking a mineral resource by 90%
How can a mineral resource be downgraded by 90%? This is a simple explanation most geologists are not aware of.

Obtaining reliably oriented core at the rig is only the first step in the process of dealing correctly and efficiently with oriented core. Individual orientation marks need to be checked and orientation lines constructed from those of high confidence. This post looks at processes and problems associated with checking orientation marks, constructing orientation lines, measurement of data and recognition of problems in data distributions

The mining and exploration industry spend too little time interrogating the data that is most routinely used. Unusable structural data is commonly taken from oriented core yet incorporated into exploration and mining studies, which may result in severe consequences. Brett Davis, in part 1 of three posts, discusses common drill core orientation problems and what to do about them.
