It seems to me that simply getting a simple reversal of Ortega's "pronouncements" really won't help either KRY or GRZ in the long term.
As Gold Reserve discovered, getting the environmental permit issued and in their hands didn't get them anywhere, because suddenly the previously unknown "Initiation Act" jumped into the picture and stopped the mine building in its tracks.
There is no reason to assume that KRY won't suddenly find similar obstructions like, road permits, water permits, explosive use permits and probably even dog licences (for the security personel's guard dogs) will all be thrown in as obstructions by petty officials anxious to cash in on the apparent bonansa to supplement their government salaries and allowances.
For that reason I would expect that the current negotiations will probably be much more wide ranging with the companies (KRY and GRZ alike) being prepared to give a little away in exchange for legally binding assurances that there won't be additional "administrative road blocks" erected every time they attempt to move to the next stage of development.
They really have no option; the past performance of the Venezuelan officials has been so erratic and incompetant that anything less than a published presidential decree specifically fast tracking and guaranteeing that all approvals, permits and permissions WILL be granted and granted within a specific limited time frame is worthless.
If the government won't agree to this both companies and their shareholders would be better served by walking away from Venezuela entirely and leaving the mess in the hands of the lawyers.
Anything else is just a death of a thousand cuts...
