Like going to the dentist, mineral exploration and discovery can involve a lot of drilling and a fair amount of (financial) pain. And much like your friendly neighbourhood dentist, the longer it takes to understand what’s happening, the more it costs.
When it comes to getting information about the minerals and chemistry of a single drill hole, the process can take up to three months. This is because a typical setup involves: setting up the drill site, drilling, extracting rock cores, sampling and logging those cores and sending the samples to a laboratory (which is often a considerable distance from the exploration site) for analysis. Then there is the process of entering and analysing the data, popping the findings into a database and getting it back to the company, so they can make a decision – it’s more complex than a root canal and much more expensive.
To speed up the process of understanding the mineralogy and geochemistry of drill hole cuttings we developed a portable lab, one that can be fitted to the exploration drill rig and analyse in real-time.
Instead of taking three months this process now takes about one hour – that’s more than 2000 times quicker than the current arrangement.
We’ve called this technology Lab-at-Rig®. Developed in partnership with Imdex and Olympus Scientific Solutions Americas, this onsite lab can be fitted to a diamond drill rig and a solid recovery unit to drastically speed-up the process of analysing an exploration site.
The lab includes a sample preparation unit that collects solids from drill cuttings and dries them; X-ray fluorescence and X-ray diffraction sensors to provide chemistry and mineralogy of the sample respectively; and the capability to upload that data to the cloud for analysis, in less time than it takes to watch a movie.
The project came about back in 2011, when a group of researchers were watching a diamond drilling operation near Adelaide and asked a simple question: ‘what if we could analyse the cuttings separated from that fluid in real time?’ We now know the answer: we can save a lot of time and money.
And now, after two years of research and development we’ve just announced that we will be commercialising Lab-at-Rig® and bringing this technology to the world, with the help of our commercialisation partner REFLEX.
With the prototype becoming a reality, perhaps we should turn our attention to making dentist visits quicker.
The Lab-at-Rig prototype was developed under the Deep Exploration Technologies Cooperative Research Centre (DET CRC).
CSIRO, Imdex, Olympus, University of Adelaide and Curtin University are now working on the $11m collaborative DET CRC Lab-at-Rig Futures Project, which will build the next generation system to cover: new sensor technologies, improved data analysis and processing for decision making, and development of the system for new applications and drilling platforms.
