UW Underworld Resources Inc.

Underworld Resources Inc. (TSX VENTURE: UW) is pleased to announce further assays from its initial drill program at the 100% owned White Gold Project, Yukon Territory. Hole WD-012 at the Golden Saddle prospect returned 4.16 g/t Au over 15.99 meters from a depth of 116.51 meters.

Hole WD-012 is the fifth of six holes drilled at the Golden Saddle prospect to intersect the north dipping zone of gold mineralization. Hole WD-010 was lost prior to reaching the target depth. Mineralization at Golden Saddle is open for expansion along strike and down-dip.

Underworld Resources completed the 13 hole, 1,243 meter initial core drilling program in July. Press release #5 (July 23, 2008) reported the gold discovery at the Golden Saddle prospect grading 4.03 g/t Au over 19.58 meters, from 12.99 meters in drill hole WD-004 and 4.58 g/t Au over 16.61 meters, from 14.74 meters in drill hole WD-005. Press release #6 (August 6, 2008) reported 4.2 g/t Au over 16.03 meters from 62 meters in Hole WD-009 and 5.74 g/t Au over 21.58 meters in hole WD-013.

A second phase of core drilling has commenced. The objective is to expand the mineralization at Golden Saddle and to test several other targets within the White Gold Property targeting favorable gold in soils. This second drill program is expected to be a minimum of 1,500 meters.

Highlights of assays received to date and an estimate of the true thickness of each interval are provided in the table below:

Forward Looking Statement

Some of the statements contained in this press release are forward-looking statements. Forward-looking statements are not historical facts and are subject to a number of risks and uncertainties beyond the Company's control, including, but not exclusively, statements regarding potential mineralization, exploration results, completion of work program and studies, and future plans and objectives of the Company. Resource exploration, development and operations are highly speculative, characterized by a number of significant risks, which even a combination of careful evaluation, experience and knowledge may not eliminate, including, among other things, unprofitable efforts resulting not only from the failure to discover mineral resources but from finding mineral deposits which, though present, are insufficient in quantity and quality to return a profit from production.

The TSX Venture Exchange does not accept responsibility for the adequacy or accuracy of this release.
