transmission imaging; and X-ray fluorescence spectroscopy. Te two methods are combined in a novel way to get information from the stone’s interior in 3D. Together with the measured weight of the samples, a mineral model of the entire volume of the drill cores can be formed.

Scanning drill core with the GeoCore



Mikael Bergqvist describes how X-ray vision through the drill core can be used for enhanced mapping of mineral resources


ovel scanning technology is enabling the mining sector to completely rethink how geologic information is processed and

analysed. Orexplore’s drill core scanner, GeoCore X10, delivers digital geology at a touch of a button. Data is easily accessible


from anywhere, using Orexplore Insight or through export into the user’s favourite geological modelling tool. Te technology originates in Swedish medical X-ray research and consists of the combination of two well-proven X-ray measurement methods: X-ray

X10 provides on-site structural 3D imaging, geochemical sample analysis, measured bulk density and rock mechanical data. It is non-destructive and preserves the bed rock formation. Te system is designed for fast and efficient on-site use, also in remote locations, with flexible options for data transfer and storage. Orexplore’s Insight software brings

powerful, instant visualisation of the analysis results and allows the user to annotate linear and planar structures; with oriented drill core, the orientation is preserved and the structures can be annotated and exported also in reference to the collar coordinate system. Tis takes the burden of doing coordinate transformation off the geologist. Te user selects ranges for data export, and the type of data: structures, density, elemental concentrations, along with the chosen annotations. One can also extract information on grain size, distributions and texture.

MISSING PIECE OF THE PUZZLE By combining the data sets, the geologist can make new connections; a seemingly simple data type – such as continuous density measurements along the drill hole – might provide the missing piece of the giant underground jigsaw puzzle, characterising the demanding task of building a model of the site specific geological conditions.

Continuous data also means a lot of data. Tis conveniently lends itself to what, in modern words, often is referred to as data mining. Orexplore partners with miners and explorers across the globe, to figure out how to best extract and automate actionable information, and to establish new and updated workflows based on the new information streams. Tese collaborations allow the company to further develop the analysis capabilities of the GeoCore X10 and associated algorithms, ensuring that industry demands are identified and met.
