🞉 Why attend
The right drilling strategy can save millions.
How much drilling is enough to deliver reliable resource estimates and meet classification standards, without overspending?
This question is critical at every stage of a mining project:
– In early exploration, it can determine whether a project is viable.
– In production, it directly impacts mine planning, operating costs, and product quality.
Drill Hole Spacing Analysis (DHSA) offers an objective, data-driven approach to optimize drilling programs and support smarter investment decisions.
🞉 What you’ll learn
In this webinar, you’ll discover how DHSA helps you:
– Prioritize targets: Identify where drilling density should increase, decrease, or remain unchanged.
– Meet classification requirements: Estimate the additional drilling needed to reach a desired resource classification, essential for budget planning.
– Support grade control strategy: Recommend drill densities that capture short-term variability and meet mill or product specifications.
– Map variability across domains: Compare zones to pinpoint areas of high variability or insufficient data.
See the methodology in action: Learn how conditional simulations power DHSA, with real-world examples for both resource classification and grade control.
🞉 Who should attend
This webinar is ideal for resource geologists and geological engineers, exploration managers, mine planners, and any professionals seeking to optimize drilling budgets without compromising data quality.
