The document outlines the steps involved in a mineral exploration program from initial prospecting through ore reserve estimation and pre-feasibility studies. It includes stages of geological data gathering and interpretation, sampling and drilling techniques, analytical laboratory methods, and flows between stages. Key stages involve reconnaissance mapping, rock and soil sampling, geophysical surveys, drilling programs, geological interpretation to identify ore deposits, and reserve estimation. A variety of analytical techniques are used to identify elements in samples collected.
