Miscellaneous Exploration
Report and Map
Digital Data Available
Comment Diamond exploration consisted of ground gravity, magnetic and electromagnetic surveys on nine geophysical targets, diamond drilling, airborne magnetic and electromagnetic surveys, heavy mineral sampling, ground truthing and mapping.

Activity Drilling
Comment Three diamond drill holes were drilled to test specific targets. No kimberlite was intersected.
Details Method/Medium Scale of Work
Diamond Drill Surface Grid/Target-Specific
Activity Geology
Comment A total of 91 geophysical anomalies were inspected in the field to assess them as potential targets for diamond exploration. Two areas were mapped in detail - one, the Courageous Block, the other, the SeaHorse Block. Maps and photos are include in the report.
Details Method/Medium Scale of Work
Bedrock Mapping Grid/Target (1000-10000)
Bedrock Mapping Core Logging
Activity Geophysics, Airborne
Comment The airborne survey was conducted to try and detect magnetic and/or conducctive zones that might reflect kimberlite targets and to provide information that could be used to map the geology and structure of the area. A multi-frequency multi-coil electromagnetic system was employed , supplemented by a high sensitivity cesium magnetometer and horizontal magnetic gradiometer. Results are discussed within this report.
Details Method/Medium Scale of Work
EM Multi-Frequency Reconnaissance
Magnetics Reconnaissance
Activity Geophysics, Ground
Comment Magnetic surveys were conducted with proton precession GEM magnetometers using station intervals of 10 m along grid lines for grids with 25, 50 or 100 m spacing. HLEM surveys had readings taken every 20 metres using coil separation of 100 and 200 metres. The instrument was a max-min. Frequencies read were 880, 3520 and 14,080 Hz. 300 gravity reading were taken to evaluate targets on five claims. Results for each grid are listed within this report.
Details Method/Medium Scale of Work
Gravity Grid/Target-Specific
Magnetic Total Field Grid/Target-Specific
EM FD phase, mobile tx: Horizontal Loop Grid/Target-Specific
Activity Lab Work / Physical Properties
Comment Results of the lab work are included in this report.Soil samples were analyzed by ICP/MS for 41 elements plus 12 rare earth elements.
Details Method/Medium Scale of Work
Grain Separation (mag/grav/visual)
Activity Sampling
Comment A total of 236 till samples and 1053 soil samples were collected over the areas of interest.
Details Method/Medium Scale of Work
Sediment, In Situ/Soils Reconnaissance Sampling
Sediment, Glacial/Till Reconnaissance Sampling
