Drill Hole Spacing Analysis – DHSA
"The DHSA training was really great! Even though it was only a two-day course, everything was clearly explained and easy to follow. I especially liked that, even without much simulation experience, we could still follow along using Isatis.neo. I can already see how it will help me improve my work."
"I was surprised by how easily I stayed focused through two days of online training, even with the time difference. The theory was easy to grasp, and we applied it right away in the software. I can't wait to use it on a real project. The trainer is one of the best mentors and teachers: he knows the formula, the reasoning behind it, and how to apply it. I'll be back for another course."
Objectives
Make smarter drilling decisions by mastering geostatistical simulations. Learn how to quantify grade uncertainty as a function of drill spacing and production volume and design optimal drilling meshes that balance costs, recovery, and dilution. Gain practical skills to improve resource classification, support strategic mining decisions, and effectively reduce geological risk.
Target audience
Mining professionals – including resource, exploration, and mine geologists, as well as mining engineers and consultants – who aim to develop cost-effective sampling strategies and optimize drill programs to achieve more reliable short-term grade estimations, greater classification confidence, and reduced risk.

What the course includes
- Balanced learning approach. Theory paired with practical applications, so you understand and apply the concepts.
- Hands-on software training. Computer exercises in Isatis.neo, on real datasets.
- Personalized feedback. Individual guidance from experienced trainers throughout the online sessions.
- Comprehensive resources. A temporary software license, course documentation, journal files, and datasets to keep and reuse after the course.

Prerequisites
This course covers advanced geostatistical concepts. We recommend that participants have a solid foundation in variography and kriging. The course Mineral Resource Estimation by Linear Geostatistics provides an excellent foundation.
