SPECIAL FOCUS: MAPPING MINERAL DEPOSITS
The GeoCore X10 at Asarel-Medet
REAL-WORLD CASE STUDIES Two such examples are the engagements with Asarel-Medet, a Bulgarian large scale low concentration Copper mine operation, and Hellas Gold, at the Kassandra Mines in Halkidiki in Greece, a gold, silver, lead-zink and copper operation, both through the EU co- financed Horizon2020 project X-Mine, under grant agreement No 730270. Desislav Ivanov at Asarel-Medet comments: “Te scanner is used in specialised geological exploration, together with the Insight software for result assessment and analysis, with a goal to improve ore mining and processing efficiency.” Te results are then used in ore deposit modelling and mining operations planning software systems. And there is a long-term vision of these methods, revolutionising the exploration and

characterisation of existing and new deposits. Te mineral grain size, their distribution and the entire structural, geological, geochemical and mineralogical information would be known even at the exploration stage. In the long run, the goal is more efficient mining and exploration and more precise location of mining sites, which directly leads to less mining waste and lower environmental impact. One of the X-Mine project’s goals is also to make smaller and complex deposits economically viable, in turn providing Europe with increased mineral resources. In Greece, Sofia Kalampaliki at
Hellas Gold used the scanned data for three purposes: digital high resolution structural core logging; quick and non- destructive identification of geotechnical features; and data enhanced 3D Geo modelling
AWARD-WINNING SOLUTION A
t the end of 2020 Orexplore was named a winner of the Swedish Mining Innovation
Award 2020. “We are at the absolute forefront of technology and I am extremely proud of what our talented employees have achieved! That Swedish Mining Innovation highlights
It was particularly interesting to see
how measured structures in the oriented drill cores could be imported into Leapfrog and aligned with the global coordinate system. Another key finding (and natural next step) would be to incorporate the produced density model to the monthly reconciliation process comparing mine and mill output. Although the trend to digitise and automate mineral mapping of deposits is clear, there are two critical issues that need to be resolved. Firstly, it is important to turn data into useful information, forming a basis for decision-making and efficiency. Te second challenge is to overcome the tradition within the mining industry of working in silos with very little communication between departments. Te information needs to be shared throughout the value chain for this “big data” to have a proper impact and effect.

and rewards innovations in the field of digital mineral analysis feels extra important as it points out that continued digitisation and automation of mapping of discoveries is the future and contributes to more sustainable and efficient mining,” comments Mikael Bergqvist. l
