Innovative Deep Targeting in Viscaria Using a Novel Simultaneous Sparse Surface 3D Seismic Array with Integrated Downhole Hydrophone and Distributed Acoustic Sensing System (NAVIS)

Description

The Viscaria deposit is rich in copper that is accompanied by deep zones of iron oxide mineralization. The recently discovered D and ABBA zones suggest that Viscaria could become a major Cu(Fe) producer. A significant challenge in mapping the deposit is the complex geology, which includes zones of highly folded structures at depth. Understanding these structures is crucial for the successful development of the mine.

The project plans to utilize a hydrophone-based system for slim-hole boreholes alongside fiber-optic Distributed Acoustic Sensing (DAS) technology for detailed mapping of deep, folded mineralized zones. This will reduce the risk in the mining operations and facilitate full exploration of Viscaria’s potential at greater depths. This system will contribute to more cost-effective methods for mapping Swedish raw materials, which is a crucial factor for local industry. Furthermore, 3D modelling with information from both the surface and the boreholes will enhance the understanding of the physical rock properties, providing new insights into the site's deep geology.
