power resources

I notice that Power Resources listed today at a significant premium to the issue price. As reported in Business News by Jenelle Carter:

"Shares in Applecross-based uranium explorer Power Resources Ltd made a strong debut on the Australian Securities Exchange today, opening at 27 cents or more than 25 per cent up on their offer price.

The listing follows a successful $2.2 million initial public offer in November 2007, in which 11 million ordinary fully paid shares in the company were subscribed by investors at 20 cents per share.

The company did not accept oversubscriptions.

Power has a 100 per cent interest in two projects (one granted and one application) in Western Australia that are
considered highly prospective for sandstone hosted uranium and deposits.

The first is the Uaroo project, located 25 kilometres north of the Paladin Resources Ltd-owned Manyingee deposit in the Gascoyne region of WA, which contains a published JORC compliant indicated resource estimate of 8,080 tonnes of contained uranium oxide grading 1,000ppm, and an inferred resource estimate of 2,810 tonnes of uranium oxide grading at 500ppm.

Similar uranium mineralisation is also hosted at the Scimitar Resources Ltd-owned Bennetts Well deposit about 15 kilometres northwest of Power's uaroo project."

If the market can value Power at a premium when they have similar deposits as SIM, how come SIM seems to languish in the price department?
