What a proper sample can tell us in terms of geology and mining exploration
Course Type Classroom Courses
Duration 5 days
Why should you attend?
The representativity (and thus the usefulness) of a soil/stream sample is driven by many parameters: initial geochemical signature, weathering, erosion, chemical dispersion, chemical/mechanical traps, etc. There is no universal "good practice” but this course is designed to give attendees an overview of the main mechanism and to help them to ask themselves the good question before any geochemical survey.
Demonstrate the significance of all parameters controlling the geochemical content of a sample;
Understand the relations between working scale and sample representativity.
Give attendees the essential tools for multi-elementary geochemical interpretation.
This course will mix theoretic consideration, case studies and practical exercises on data interpretation. The course may integrate Field Course exercises, depending on the location.
Practical exercises can be done on company’s attendees data set.
No specific requirement for this course that can take place in any meeting room with validated HSE characteristics, in your company premises or elsewhere. If a short field trip or field sampling campaign is added, specific requirements will be compulsory, and adapted to the local conditions. In such a case, field evaluation and emergency measures will have to be anticipated and will be clearly specified in a published report before the course.
5 days (35-40 hours) is the ideal time, including 1 field trip day.
Alteration and its geochemical impacts;
Sample representativity and homogeneity: technical consequences
From sampling to analytical results;
Data management: tools, constraint;
Elaboration of a geochemical survey (practical work).
Geochemical data interpretation
Some theoretical considerations
A few words on softwares
Field trip (if required and possible)
The course has been designed for geologists willing to maximize mining exploration in terms of time and money by using geochemical soil/stream samples.
Attendees must have a general knowledge of geology and if possible some experience in field exploration.
As an exploration geochemist graduated from ENSG School (Nancy, France), Yann has 31 years of experience in geochemical exploration, including 20 years with BRGM (French geological survey). West and Central Africa, South America, India, Russia were the main working place for mining exploration, mineral inventories and environmental mining assessment. Currently independent consultant, he mainly works for international mining companies in Western Africa as geochemist, regional exploration leader and exploration data manager.
