DownanOut:

The link you provided is a great read (Hana announces positive preliminary economic assessment for the Ghanzi Copper-Silver Project) . The Banana Zone and Zone 5 project Cupric bought into in February 2013 are very compatible in terms of grade and recovery to DML's Boseto.

The value of DML's Boseto to Cupric, is that they don't need to spend at least the following capital:

Concentrator plant USD125.1M
Power generation USD19.3M
Tailings dam and piping USD9.9M
Sub-total USD 154.3M

and a proportion of the following based on the reduction in their project scope:
Accommodation Originally 15.3, reduce by say USD11M
Indirect (managing contractor, owner's costs, spare, etc.) Originally 54.0, reduce by say USD41M
Sub-total USD52M

TOTAL USD208M

In my opinion, DML managment should be negotiating towards this number as a minimal acceptable number for all stakeholders.
