Geochemistry
Geochemistry is a scientific approach used in mineral exploration to find valuable deposits by studying the chemical makeup of rocks, soil, and water. It's like detective work that helps exploration companies decide where to look for minerals and metals. Companies use geochemistry alongside other exploration methods because it can help them save money by identifying promising areas before expensive drilling begins. This field combines geology (study of rocks) with chemistry, making it essential for mineral exploration and environmental assessment work.

Example Interview Questions
Senior Level Questions
Q: How would you design a regional exploration program using geochemistry?
Expected Answer: A senior geochemist should explain how to plan sampling locations, choose appropriate sample types (soil, stream sediment, rock), ensure quality control, and integrate results with other exploration data to identify drilling targets.
Q: How do you manage quality control in a geochemical sampling program?
Expected Answer: Should discuss implementing proper sampling protocols, using control samples, selecting appropriate analytical methods, and ensuring data validation procedures are followed.
Mid Level Questions
Q: What sampling methods would you use for different terrain types?
Expected Answer: Should be able to explain when to use soil sampling versus stream sediment sampling, and how to adjust sampling density based on terrain and project goals.
Q: How do you interpret geochemical results to identify exploration targets?
Expected Answer: Should demonstrate understanding of statistical analysis, mapping of results, and how to identify anomalies that might indicate mineral deposits.
Junior Level Questions
Q: What are the basic steps in collecting a soil sample?
Expected Answer: Should explain proper sample collection techniques, labeling, documentation, and basic field procedures to avoid contamination.
Q: Why is chain of custody important in geochemical sampling?
Expected Answer: Should understand basic quality control and the importance of tracking samples from collection through analysis.
