Mineral/Lithological mapping and identification of marker horizons and recognition of ferruginous alteration zones (gossans) likely to be Ni-Cu mineralization indicators.
Geological studies
Northern Quebec — Recognition of ferruginous alteration zones (gossans), which indicate Ni-Cu mineralization
Project Start
Summer of 2002 and 2017
Project Duration
6 and 2 months
Purpose of project conducted for the Canadian Space Agency
- Mineral/Lithological mapping and identification of marker horizons;
- Recognition of ferruginous alteration zones (gossans) likely to be Ni-Cu mineralization indicators.
Context
Mandate carried out for the Canadian Space Agency in Northern Quebec. Exploration and mining activities for Ni-Cu were in progress in two study areas, covering a vast territory in a region difficult to access:
- Raglan mine area, within Cape Smith Belt (in red on the map);
- Labrador Trough area (in yellow on the map).
Need to identify geological and mining targeting units in a Northern region, including:
● Improving mapping of lithological units and alteration zones;
● Targeting sectors that were favourable for nickel and copper mineralization.
Solution implemented: Remote Mapping
Analyzed images
- High-resolution hyperspectral images in the case of the Raglan mine area;
- Multispectral images in the case of the Labrado Trough area
- Spectral signature;
- Texture and geometry parameters;
- Lithological context.
Results
Cape Smith belt area
Labrador Trough area
