Spectral imaging to survey Sweden's mineral deposits

Hyperspectral imaging is to be used to scan and analyse 200km of drill cores representing 100 years of geological exploration for the Geographical Survey of Sweden.

The geologists will use hyperspectral imaging technology from Specim to conduct one of the largest optical and mineralogical core scanning projects in the world. The aim is to build up a uniform national drill core database for geologists to use as a research tool.

Together with its South-African partner, GeoSpectral Imaging (GSI), Specim will scan and analyse data of archived drill cores by capturing VNIR, SWIR and LWIR wavelength spectral images as well as high resolution RGB images.

Specim Spectral Imaging is a manufacturer of hyperspectral imaging instruments and systems.

‘We are looking forward to working with Specim. The project will extract additional information from our voluminous asset of drill cores. The information - freely available on internet - will be of great value for exploration, research and mapping,’ said Kaj Lax, head of the Mineral Resources department, Geological Survey of Sweden. ‘The drill cores cover more than one hundred years of exploration. This project will transform Sweden’s mineralogical data into digitised, actionable insight.’

‘The combination of Specim’s SisuRock scanner and GeoSpectral Imaging’s processing solution provides the best-in-class solution needed to address the requirements of the client, the high speed and performance is what makes this project economically viable,' said Rainer Bärs, project manager of hyperspectral sensors and software at Specim. ‘We look forward to working with the Geological Survey of Sweden as they enter a new era in their minerals information activities.’

‘Specim has made a strategic decision to move in the supply chain from an equipment manufacturer to a service provider through internal structuring and by partnering. This contract is a confirmation of our strategy working in action,’ said Risto Kalske, chairman of the board, Specim. ‘We appreciate Sweden taking the lead in digitising their national archive, and trust other countries will adopt similar practices enabled by new services and solutions.’
