Fronteer's Aurora Closes Initial Public Offering and Begins Trading on Toronto Stock Exchange.

VANCOUVER, British Columbia -- Fronteer Development Group Inc. (TSX:FRG)(AMEX:FRG) is pleased to announce that its subsidiary, Aurora Energy Resources Inc. ("Aurora")(TSX:AXU), has closed its Initial Public Offering ("IPO") of 6,944,444 shares at a price of Cdn$3.60 per share, for gross proceeds of Cdn$24,999,998.

Aurora's common shares are listed on the Toronto Stock Exchange and will commence trading today under the symbol AXU. For full details of Aurora's IPO, please see their most recent release which can be found at: www.aurora-energy.ca.

Fronteer remains the controlling shareholder of Aurora following the IPO, with an ownership of 50.2%. Fronteer's ownership may be further modified to 49.3% upon the underwriters exercising their full over-allotment option on Aurora within the next 30 days.

"We are very pleased, that with minimal dilution to our ownership of Aurora, we have created a new, uranium focused, vehicle to fund the Labrador uranium projects," says Fronteer President & CEO Dr Mark O'Dea. "Aurora can now be valued in the context of its uranium peer group, with the expectation that it may reach new valuation highs and drive added value back to Fronteer shareholders. In addition, this transaction will allow Fronteer's significant gold assets to attain their own competitive valuation."

AURORA'S URANIUM PORTFOLIO

Through Fronteer's efforts in coastal Labrador over the past 12 months, the Michelin deposit ("Michelin") has more than doubled in size. Michelin is now one of the largest undeveloped uranium deposits in Canada, with a measured and indicated resource of 22.2 million pounds and an additional inferred resource of 13.4 million pounds. Aurora management anticipates that with further drilling, the tonnage of Michelin has the potential to increase significantly, and new uranium discoveries may emerge in the district.

In addition to Michelin, Aurora owns four other deposits called Nash, Inda, Gear and Rainbow, which are also open for expansion.

These five deposits, when combined with two new uranium discoveries at Jacques Lake and Otter Lake, and multiple drill ready targets, attest to the untapped mineral potential of Aurora's 829 square kilometre land package in coastal Labrador.

The 12 month exploration budget for Aurora is $14.5 million, which is anticipated to include approximately 40,000 metres of drilling. The 2006 exploration program is scheduled to commence in April.

Uranium resources referred to for the Nash, Inda, Gear and Rainbow deposits are historical in nature, and were estimated prior to NI 43-101. Fronteer has not undertaken an independent investigation of the resource estimates or independently analyzed the results of the previous exploration work in order to verify the classification of the resources, and therefore the historical estimates should not be relied upon. Fronteer believes these historical estimates provide a conceptual indication of the potential of the property and are relevant to ongoing exploration. See Fronteer press release dated December 8, 2004.
