Innovative Deep Targeting in Viscaria Using a Novel Simultaneous Sparse Surface 3D Seismic Array with Integrated Downhole Hydrophone and Distributed Acoustic Sensing System (NAVIS)
Purpose and goal
The Viscaria deposit is rich in copper, along with deep zones of iron oxide mineralization. The recently discovered D and ABBA zones suggest that Viscaria could become a major Cu(Fe) producer. A key challenge in mapping the deposit is its complex geology, including zones with strongly folded structures at depth. Understanding these structures is crucial for developing the mine.
Expected effects and results
The system will contribute to more cost-effective methods for mapping Swedish mineral resources, which is important for local industry. In addition, knowledge of physical properties will be improved through 3D modeling using data from both surface measurements and boreholes, providing new insights into deep geology.
Planned approach and implementation
The project plans to use a hydrophone-based system for narrow-diameter boreholes and fiber-optic distributed acoustic sensing (DAS) technology for detailed mapping of deep, folded mineralized zones. This will reduce mining risks and enable the full deep potential of Viscaria to be explored.
