Mineral exploration and mining
Chronosurveys offers you a wide range of exploration services that can help carry your mineral project from grassroots into pre-feasibility and feasibility stages and in a quick, safe and cost-effective manner.
Our value lies in holding a team of multi-skilled geoscientists with a strong academic support and international experience with exposure to different geological settings and varied commodities (including gold, manganese, iron ore, base metals).
Where needed we are also able to increase your own geologists and field assistants knowledge and value by providing them with specific training, practical courses and/or workshops in Portuguese, English and French.
Coal Stratigraphy
Need to evaluate the stratigraphy of coal measures, correlate between wells or mine sections? Palynology of coal beds and interbedded sediments can provide the needed calibration. Well, outcrop and mine samples are suitable.
Shale-hosted ores
Many transition metal deposits around the World are hosted by black shales and other fine-grained sedimentary rocks. Despite the common metamorphic alteration, palynology and other disciplines can still be used for stratigraphic purposes.
Rock salt and evaporites
Chronosurveys refined a method to extract microfossils from evaporites and associated sediments. The method has been effectively used in well, mine and outcrop samples from Permian to Miocene age, allowing to refine the stratigraphy and depositional environment interpretation and determine thermal maturation.
