A first sight, a LIMS might seem of little interest to most mining or exploration companies, but when one considers that a mine or exploration project may be submitting samples for assay to several different laboratories, in-house or out-of-house, worldwide, for different analyses (atomic absorption spectrography, chemical analyses, fire assays, chromotography, etc.) and that this complex two-way or multi-way traffic may be highly confidential, then a system that automatically manages and secures it seems very well-suited to the industry's requirements.
