Brinkley is going to amaze us, although a bit expensive The Katangan U-deposits are going to generate more than U3O8
Googling for "Kasompi" I found a chart on Google Maps Apparently from a Belgian geologist (13/11/05) It places a list of (old) mines, many (+20) I've never heard of before Stay alert for every NR related to Katanga!
Kasompi: another deposit of rare-earths minerals such as schuilingite-(Nd) and gyisinite-(Nd). We also find arborescent pale-green lodes of glaukosphaerite. (Nd = US$30kg)
