Has anyone done a comparison between
KFE & TNG?. There seem to be very similar situations excellent TNG being Aust based and about 2-3 years ahead of the current situation of KFE prior DFS.
Despite location, mineral mined being Vanadium-Titanium-Iron Ore rather then just Iron Ore, and the lower cost of production for KFE both companies seem to be fairly similar?... but from reading posts, information on TNG it seemed to go from a low of $0.02c SP to over $1 then very quickly retract back to $0.15 cents where it remains today.
I'm just curious as to why this retraction and if history indicates future performance maybe we can learn something from this and/or can we expect the same volitility with KFE? Maybe a long bow to draw but maybe worth an analysis or am I comparing Apples with Oranges.
Just a learning investor and curios so please don't shoot me down to hard if I'm way off the mark.
Thankyou
