I don't understand the benefit to DVP of selling down Woodlawn.
Bill has explained (my words) that he is avoiding dilution by creating an internal income stream to facilitate growth. This was the rationale for the mining services arm. This has been proven to be successful.
We now have the additional income producing WL adding to our cash flow.
Selling a portion of WL equates to dilution in my reasoning. Selling 20% of WL is perhaps similar to issuing another 50m shares.
Often selling down an asset is done to spread risk, however we are through the high risk phase.

Aren't we in an even better position to self fund, than when WL project kicked off?
I appreciate (as Bill has said) that the part sale of WL is not unless the numbers are there and if not sold SS will push out time wise.
I would rather the delayed gratification and simplicity of funding own own growth.

I balance my thoughts above with the proven record of Bill Beament. I would be happy to be educated on why my reasoning is flawed.
