Ann: Further Promise at Transylvania, page-17

Many investors, investing in exploration juniors are bored of waiting for exploration results or pretty pictures of drill cores, despite that almost all mineral exploration involves drilling to discover what is below the surface. There is many examples of mine failures that result from misuse or misinterpretation of mineral exploration data and it is here that the greatest follies occur. Block model grade interpolation is the greatest pitfall for mine production-reserve model reconciliation. Often grade interpolation can introduce an element of bias by grade smoothing, exacerbated by a lack of geological knowledge and geological domain definition, and failure to adequately deal with outliers assays. In my experience the single greatest cause of mine failure is inadequate study of the orebody. Patience is required!
