This company is a chancer with lousy owners. They always seems to be on the search for the next big thing but never succeed. They were once $1.95 per share. An incredibly hopeless performer.
As a side question, why is it that you don't like magnetite much?
I am generalising here but hematite preferred mainly for its DSO properties. I don't hold stocks until production so prefer the instant market appeal of a DSO product.
Hematite may generally contain higher concentrations penalising elements but by the time that becomes a financial factor I am long gone from the share registry.
