"another reason for Teck to buy us out 100%, reduce legal and accounting fees in understanding this legacy contract..."

Yet another reason would be the tax loss accumulated by CUU. At the end of 2011, there's approx $41M deficit (I assume a similar amount for tax purposes) for CUU and say $45M end of 2012. If Teck buys us out, it can amalgamate the two and utilize the tax loss carried forward, which, assuming a 40% tax rate for Tech, will be worth some $18M in tax savings; not a huge amount, but why not grab that from the tax man when you can!
