"Borehole & ablation HAS to work or this is stranded"



Why wouldn't it work, I ask?

It's working for Cameco at Cigar Lake, the worlds most prestigous Uranium project.


From the Cameco site:


# The high grade ore will be removed by a non-entry method jet boring system that will be deployed within access tunnels being developed about 25 metres beneath the orebody.

# Jet boring involves using water under high pressure to carve out cavities in the orebody and then collecting the resulting ore slurry through pipes.

# The Cigar Lake mining process also involves backfilling the cavities in the orebody with concrete once the ore is removed.

# Ore collected by the jet boring system will be taken to underground grinding and thickening circuits and then pumped to surface as slurry. At the surface, the ore will be loaded in special containers for truck transport to the mill.
