GEO-CONSULT has been providing petrographic services to mining companies, exploration geologists and prospectors in all parts of the world for the past 20 years. Dedicated to excellence, the primary objective is to provide geologists with detailed, high quality petrographic reports, assisting them in their search for new ore deposits and in their re-interpretation of old deposits. Specialized in ore-related alteration and associated mineralization, including magmatic and volcanogenic massive sulfides, gold and other precious metals, rare earth (RE) minerals, and exotic minerals.

PETROGRAPHIC REPORTS will include microscopic examination of thin sections with transmitted and reflected lights, detailed description of mineralogy and texture, classification of rocks where possible, visually estimated modal proportion of minerals, and description of primary and secondary minerals and their paragenetic sequence. In mineralized samples, the genesis of ore will be estimated. All reports will include 2 or more photomicrographs of each thin section taken by a digital Leica cooled camera, a cd with file(s) and 2 hard copies of the report.
