Comment Diamond exploration included gechemical sampling of 1253 reconaissance till samples, and airborne geophysics including 14,900 line km of EM and Mag. Several indicator sources were suspected and a dozen or so geophysical targets identified. Royce Group: An ammended report is attached to the original with this shorter list of claims that the work is being applied to - see complete list under illustrations comment.

Activities
Activity Geophysics, Airborne
Comment Several potential targets were identified, the highest priority target is one with coincident magnetics, VLF-EM, topography and is at the termination of the mineral train from the till samples. Both positive and negative magnetic responses delineate targets.
Details Method/Medium Scale of Work
Magnetics Reconnaissance
EM VLF Reconnaissance
Activity Lab Work / Physical Properties
Comment Most of the 1256 samples collected were processed, sorted and analysed by C.F. Minerals but due to delays, the remaining 416 samples were sent to Overburden Drilling Management Ltd. for processing and sorting while the electron microprobe work was done by R.L. Barnett Geological Consulting. The report states that 'no site specific conclusions could be drawn as to the origins of the indicators found throughout the property.'
Details Method/Medium Scale of Work
Grain Separation (mag/grav/visual)
Electron Microprobe Analyses
Activity Sampling
Comment Positive kimberlitic indicators were recovered from the samples taken. The preliminary report states that these are probably derived from diamondiferous kimberlites. Subsequent ammendments to the reports provide the sample numbers, sites and results but no further discussion of same.
