Process automation – drill planning and budget optimization

Often the first budget item to be cut in times of austerity is exploration drilling. We will not go into the wisdom or consequences of this decision, but rather look at a means to optimize the money available for ongoing drilling. Most geologists who have had to do drill hole layouts will have come up with any number of tools or process automations through scripts or macros that help them design a reasonable drill plan in an acceptable time frame. One such approach is described in this article.

When is a Mineral Resource not a Resource?

Many mining companies are cutting exploration budgets to survive the current mining downturn and low commodity prices. As a result, some firms either do not have enough geological and support staff or they have inexperienced staff members who do not adequately understand the geology, mining method used and processing aspects of their operation or project...
