Fusion and interpretation of drilling-derived datasets for better exploration and mining

This one-day online course  is to encourage geologists, at every level of experience, to use their full skill sets to make the best possible decisions from drilling results.


Who should attend?
The course is suitable for geologists of any experience level, working in mineral systems with poor outcrop, complex structure, geophysics and geochemistry, including minerals explorers, mine geologists, researchers and students. It is ideally suited for geologists using drill core and related data as a major component of their exploration, research or mining geology programs.

Participants will use the following provided datasets: core photography, downhole geochemical data, geophysical/rock properties data, and structural data. Good working knowledge of Excel is required; prior experience with Leapfrog, ioGAS and stereographic projection software will be beneficial but is not essential. Instructions for accessing this software, the core photography data package, and the relevant datasets, will be made available upon registration.

Course content
The main focus is on the use of drilling-derived data, including core photography, down-hole geochemical data, logging data, structural data, and additional data derived from tools such as spectral tools or scans, magnetic susceptibility etc.

  • Drill core do’s and don’ts.

  • Understanding core logging.

  • Extracting Lithogeochemistry within deformed rock packages.

  • Dealing with deformation: the poly-deformation challenge where to start, what to do, how to simplify, how to move forward, how to turn jumbled logs and random structural measurements into actual ingredients in a 3D model.

  • Dealing with alteration: the similar poly-alteration challenge, where to start, what to do, how to simplify, how to move forward, how to turn jumbled logs and random alteration observations into ore-finding vectors by combining your geochemistry with core observations.

  • Fusing geochemistry with structural geology/geophysics.

  • Drill hole logging with digital data. Realistic practical solutions are now being offered by service providers to extract multiple datasets by core scanning, generating a wave of new datasets.

Cancellations will incur a ($40) administration fee up until one week before the course commencement date & time, but you can transfer your registration to someone else from your group by notifying us, at no cost. After that date, no refunds will be issued. Should Covid restrictions preclude the face to face course delivery, the course will be taught online.
