Yes the arrangement with Vista Gold is as follows :
(From company announcement on 7th April 2008)
..........................................................
The Company pays Vista Gold no cash upfront and will pay three equal payments of US$1M,
the first once commercial production has commenced at the Project and then on the first and
second anniversaries of this occurrence.
The Company will also pay a graduated royalty to Vista Gold according to the following table.
Gold Price: US$/oz Royalty Payable to Vista Gold
$500.00 or less 0.00%
$500.01 to $650.00 2.00%
$650.01 to $750.00 3.00%
$750.01 and above 3.50%
The royalty is capped to a production maximum of 720,000 troy ounces of gold.
...........................................................

So presently with the gold price above $750 then RAU would pay Vista a royalty of 3.5% on whatever gold was produced up to a total of 720,000 ounces of gold.

Hope that helps on that point
