Actually, it is based on the ASSUMED value of the "certain assets" it traded for and a liberal amount of wishful thinking.
The agreement is "...to acquire CERTAIN ASSETS of Fonon Technologies in exchange for a MAJORITY OF THE ISSUED AND OUTSTANDING SHARES of Mabwe Minerals Inc."
I don't think the Nikitins are giving up that much for the MBMI shell. They could easily go elsewhere to pick up a cheap shell.
Also, of June 30, 2014 the RRHI only owned 64.13% of Mabwe Minerals. As the percentage has been creeping downward, I doubt the percentage is that high today.
RRHI holds no other fungible assets and is over a barrel, so half a cent per share seems over valued.
