Overview

Excerpt from Modern Mine Valuation For example, a sampler should sign each vein section sampled by him, just as the surveyor signs a plan, or a chemist an assay certificate. Again, the field data, as well as the tabulated analyses of these results, should be as clearly arranged as the time-books and store-sheets of a manufacturing enterprise or producing mine. In a word, it may safely be said that, in point of certified accuracy, mine valuation, as generally obtaining, is wofully behind the usual standard of commercial undertakings, both in principle and practice.
