Resource Estimation
Resource Estimation is a crucial process in mining where experts calculate how much valuable mineral or metal exists in a potential mining site. It's like taking inventory of what's in the ground before starting a mining project. This helps mining companies understand the value of a site and plan how long they can mine there. The process combines geological knowledge with mathematical calculations to make educated predictions. Think of it as creating a 3D map of underground resources, similar to how a grocery store needs to know how much inventory they have, but for minerals underground.

Example Interview Questions
Senior Level Questions
Q: How do you ensure the reliability of a resource estimation project?
Expected Answer: A strong answer should discuss quality control methods, data validation processes, and the importance of using multiple estimation methods to cross-verify results. They should mention experience in reviewing historical data and understanding geological context.
Q: How do you handle uncertainty in resource estimation?
Expected Answer: Should explain how they use different classification methods (measured, indicated, inferred resources), risk assessment, and how they communicate these uncertainties to stakeholders in clear, non-technical terms.
Mid Level Questions
Q: What factors do you consider when planning a resource estimation project?
Expected Answer: Should mention data collection methods, geological interpretation, cut-off grades, and how economic factors influence the estimation process. Should demonstrate understanding of project timeline and budget considerations.
Q: How do you determine appropriate sample spacing for resource estimation?
Expected Answer: Should explain the balance between cost and accuracy, discuss how deposit type affects sampling strategy, and mention the importance of statistical analysis in making these decisions.
Junior Level Questions
Q: What is the difference between a resource and a reserve?
Expected Answer: Should explain that resources are natural deposits in the ground, while reserves are the portion of resources that can be economically mined, demonstrating basic understanding of mining economics.
Q: What basic data is needed for resource estimation?
Expected Answer: Should list essential elements like drill hole data, sampling results, geological maps, and basic understanding of how this data is collected and organized.
