I have a query/ thoughts.. in an sector I'm not that familiar with. I understand this latest surge in Uranium spot has been on the back of Sprott buying up limited supply. How sustainable is this, and does it represent an a somewhat artificial inflation of the spot price. Or will the long-term demand driver's step in to support current and future price rises.
Making decisions to open previously unviable mines on the back of short term price pressure would seem careless. I haven't looked into exactly what Sprott are up to.. keen to hear input from others do have their head around the U market.
