It's Geology does look at Uranium I know. I am aware of the similarities to the Athabaska basin and the potential for deposits to be found near the regolith at the base of the sandstone. But also since the sediments are proterozoic, the early cratonization leads one to conclude that it may be favourable to diamond emplacement also. Faults projected northeast into the Arctic intersect areas of diamondiferousness there. It is a fact worldwide that similar diamond and kimberlite emplacement follows these trends (W.J. Atkinson, studies in Namibia). The Great Bear Lake area is one of the few areas that has not been looked at for diamonds although dyke emplacement of all kinds is ubiquitous.

It is evident too, in looking photos of many circular structures in the area that there may be some related to kimberlite deposition as these could not all be carbonate sink holes. Some are in other kinds of rocks. The experience of many companies I am familiar with in the territories was that a great percentage of the kimberlites were not magnetic but did show up when input conductivity anomalies were contoured in certain channels. This is parallel with the experience in Nigeria with the kimberlites there that are not magnetic but do show up in conductivity studies.

The only drawback to this area is that it is uplifted and may not have been protected enough in the last 30 million years to allow diatreme facies to survive. Yet this facies does survive in other areas of the NWT quite well and in reflection the basinal nature of the ground is evident from the rocks left there and the degree of erosion may be also surmised to a degree from the survival of the sediments.

The final only way to tell its diamond potential is to look with work. What work is done is up to the company, but looking at the input data again cannot hurt and would not be expensive. Gathering samples from areas of high energy in the area and studying aerial photos for correlation would not be hard either. The program makes sense. In the light of Major General/De Beers's studies on Victoria Island and successes north east in diamonds of there it augurs well for some kind of technical success at the very least.

It is also true that a study could be two pronged as indicator mineral collection could point to Uranium related mineralization as well. I knew when I worked at SMDC that our targets were deep seated, base of the sandstone deposits and we knew that evidence from transecting faults would be dragged by the glaciers from them and would be anomalously hot. We found three such boulder trains. It took me 3 weeks to find them.

If you know how it can be done.
