RE:RE:RE:The complex structure of the PLS deposit
You can see the minor thrust faulting where the graphitic pelitic gneiss contacts the semi-pelite so this is a fairly typical depositional setting for the Athabasca. Uranium precipitated out of solution when it contacted the graphite. The degree of faulting tends to control the fluid flow hence the distribution of the mineralization hence the overall size of the orebody. At Rabbit Lake for instance, they are still chasing mineralization to depths of over 400 metres along faulting. On the other hand, the mineralization at McArthur River does not stray too far away from the unconformity. Unfortunately it is somewhat a needle in a haystack chasing the faulting so much of the ore is not found until the mine is in operation. So the key here is to get ample starter pit ore that makes economic sense and then to continue both surface and eventually underground exploration. The mining is probably the easy bit here, the approvals process and milling strategy are the harder bit. There appears to be ample ore for a mine at say $70-80/lb.
