A good example of this is OGX. They have a couple of very high grade narrow orebodies. Drilling has been very much hit and miss with many more misses than hits despite having a reasonable understanding on the location of the high grade orebodies. Today they announced some spectacular grades (hundreds of g/t) and good continuity through u/g development work to follow one of those orebodies.
