Fronteer's Aurora Extends the Depth of Jacques Lake Uranium Deposit to 235 Metres

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Dec. 5, 2006) - Fronteer Development Group Inc. ("Fronteer")(TSX:FRG)(AMEX:FRG) announces that Aurora Energy Resources Inc. ("Aurora") (TSX:AXU), in which Fronteer holds a 47.2% interest, has announced that new drill holes from the Jacques Lake deposit ("Jacques Lake") in coastal Labrador have further expanded the size of the deposit.

Results from drill holes JL-06-43 and JL-06-45 are highly significant as they now firmly establish that uranium mineralization extends from surface to a depth of 235 metres in the central part of the deposit. Mineralization remains open at depth for further expansion.

"Aurora has delivered on one of its key 2006 objectives," says Dr. Mark O'Dea, Aurora President and CEO. "We've advanced Jacques Lake from a conceptual target to a growing uranium resource. Our findings suggest that this is just the beginning of a strategically significant uranium district."

Highlights are as follows:

1. JL-06-43 intersected 0.11% U3O8 over 29.00 metres, including 0.30% U3O8 over 3.42 metres.

2. JL-06-45 intersected two parallel zones of mineralization:

- 0.13% U3O8 over 27.50 metres; including 0.25% U3O8 over 5.35 metres, and

- 0.12% U3O8 over 10.0 metres.

To date, mineralization at Jacques Lake has been intersected intermittently over a strike length of approximately 600 metres. The best results, thus far, define a thick, central, high grade zone that is similar in size, shape and grade to Michelin, located 30 kilometres to the southwest. This high grade zone currently has been defined to a depth of 235 metres, with an average true thickness of 20 metres and remains open for expansion. For comparison purposes, mineralization at Michelin has been intersected to depths of 750 metres and it too remains open for expansion. The stated widths are between 70% and 90% of true widths

Four exploration holes were drilled to test other discrete targets along the five kilometre long Jacques Lake uranium anomaly; however, no significant values were returned. Additional drill results from Jacques Lake are pending.
