Structural Geology
The fundamental reason why your geological models may be completely wrong
Here are some reasons why we may get our geological models and understanding completely wrong.
Read MoreIf Richard Feynman was a Geologist…
Physicist Richard Feynman was famous for working from ‘first principles’. This is how I think Feynman would have approached exploration problems.
Read MoreIs ‘Vectoring’ to Mineralisation a Claytons Jargon?
What exactly is ‘Vectoring’ to Mineralisation? This post has all the answers.
Read MoreWhy I Give Geological Cross-Sections the Cold Shoulder
In this post, I question the usefulness of a geological habit universally accepted as a good thing—the geological cross-section
Read MoreA recipe for shrinking a mineral resource by 90%
How can a mineral resource be downgraded by 90%? This is a simple explanation most geologists are not aware of.
Read MoreThe missing link in exploration – Rapid 3D geological modelling
Implicit 3D modelling tools should be used by every exploration company as a geological tool, but like any other geological tool, it should be used by experienced geologists. Use it like a black box, and it will inevitably lead to disaster.

Orefind reviews the latest tool for core orientation – Ezy-Ori by 2iC Australia.
Read MoreFractured knowledge
This brief blog post is a response to a recurrent question that comes from exploration and mine geologists. The question is ‘what is a fracture?’
Read MoreStrain? What strain??!
The majority of geologists don’t understand 3D ductile strain, judging from our consultations with clients. I explain why it is absolutely critical to understand ductile strain to benefit exploration and resource evaluation.
Read MoreThe myth of sectional geological modelling: Part 2
I outline the quickest way to model geology in 3D, but it’s controversial and the discussion may offend the majority of academic economic geologists!
Read MoreEquipment check
Brett discusses the secret weapons that we use in our consulting work.
Read MoreStructure at the expense of geology
The analysis of mineralisation occurrences requires an integrated approach that should include all facets of geology, not just structure. In this post I talk about how to display this information in a small convenient format – the paragenetic table.
Read MoreStructural geology in the mine and the field – sometimes we need a hand
This post discusses a structural geological methodology that is rarely used but can be extremely powerful in terms of the information it can provide.
Read MoreWhat is a Fault?
Many geologists consider the modelling of faults in mineral deposits to be VERY important. I am not one of these geologists. To understand why I feel this way, you have to ask the question “What is a Fault?”
Read MoreGeological shortfalls – there are ways to provide a soft landing
Visits to many different mining and exploration sites shows huge diversity in the skills of geologists. This post suggests ways to manage the issue of poor geological skill sets.
Read MoreBoundary Analysis in Leapfrog
How do you decide whether to make a fault boundary hard or soft? Geologist Ron Reid, who is an Orefind-trained veteran Leapfrog user, explains how to do this effectively in Leapfrog Mining software.
Read MoreDrill core orientation – An Inconvenient Truth (Part 3 of 3)
Obtaining reliably oriented core at the rig is only the first step in the process of dealing correctly and efficiently with oriented core. Individual orientation marks need to be checked and orientation lines constructed from those of high confidence. This post looks at processes and problems associated with checking orientation marks, constructing orientation lines, measurement of data and recognition of problems in data distributions
Read MoreThe Watch Riddle – Discussion
Why is the previous post “The Watch Riddle” relevant to geological modelling and interpretation? Find out in this blog post.
Read MoreThe Watch Riddle
A parable is a short tale that illustrates universal truth.
Today’s post is a geological parable in two parts, and it starts off with a strange looking watch.
Drill core orientation – An Inconvenient Truth (Part 1 of 3)
The mining and exploration industry spend too little time interrogating the data that is most routinely used. Unusable structural data is commonly taken from oriented core yet incorporated into exploration and mining studies, which may result in severe consequences. Brett Davis, in part 1 of three posts, discusses common drill core orientation problems and what to do about them.

Last week was a busy one for Orefind. After putting the final touches to the website Orefind personnel winged their way to the mining mecca of Kalgoorlie for the AIG Structural Geology and Resources Symposium.
