No one else has the average grades for U3O8 that Canada has, which means lower processing costs and better ROI in general. The last time the spot price was $30.20 was sometime in 2005, when gold was around $ 450, so I'm not sure when that Casey article was written and I didn't notice a date in the post. The conversion price for U3O8 to gold in the article gives about $ 444/oz au so I'm guessing it's circa 2005. Anyways the point is well taken since several of the existing deposits, McArthur River and Cigar Lake, average about 20% U3O8. Who produces U3O8 and how much is well established as shown in many articles such as :

Everyone quotes spot prices but producers get more than that since the long term price is currently about $ 60/pound. However, many of the contact transactions are not publically disclosed and it appears they are negotiated on a semi-annual basis with another round coming up in April. The supply-demand curves are looking good for an upward trend in prices. There are about 437 reactors, 50 under construction and over 100 planned. The following article has a number of interesting points :

They quote a comment about the fact that about half of the fuel used in U.S. reactors actually comes from converted Russian warheads and that most Americans are unaware of that fact. Well, I didn't know that either and I suspect a lot of other people as well. If we find something at McTavish, it will have an impact on share price,just look at the price action with Hathor in 2008 when they made their hit.
