RETRANSMISSION: Underworld Commences Drilling at White Gold Discoveries, Yukon

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 11, 2009) - Underworld Resources Inc. (TSX VENTURE:UW) is pleased to announce that that drilling has commenced at its 100% owned White Gold Property, Yukon Territory. The Company has doubled the scale of the 2009 drill program to aggressively step-out along strike and down-dip of the thick intervals of gold mineralization discovered during the summer of 2008 at the Golden Saddle Zone (see NR-UW 2008-16, November 24, 2008). Two drills are on site with an option to add a third drill to the program.

At Golden Saddle, the mineralization is shallow-dipping and begins at surface. The 2008 drilling traced continuous gold mineralization for 450 meters along strike, and to 170 meters down dip. The zone is open for expansion in all directions.

Highlights from 2008 drilling at the Golden Saddle Discovery include:



--------------------------------------------
Weighted avg.
Hole ID grade (g/t Au) Length (m)
--------------------------------------------
WD - 004 4.35 g/t Au over 18.08 meters
--------------------------------------------
WD - 005 4.38 g/t Au over 17.66 meters
--------------------------------------------
WD - 009 4.20 g/t Au over 16.03 meters
--------------------------------------------
WD - 012 4.16 g/t Au over 15.99 meters
--------------------------------------------
WD - 013 5.60 g/t Au over 21.58 meters
--------------------------------------------
WD - 016 3.38 g/t Au over 14.17 meters
--------------------------------------------
WD - 020 1.87 g/t Au over 27.70 meters
--------------------------------------------
WD - 021 3.10 g/t Au over 50.70 meters
--------------------------------------------
WD - 024 2.35 g/t Au over 19.00 meters
--------------------------------------------


The Phase 1 4,000 metre core drilling program will focus on expanding the Golden Saddle Zone along strike and down-dip and will include 30 holes.

Underworld will also follow-up on the second mineralized zone at the White Gold Property, with up to 10 holes planned at the Arc Zone. The Arc Prospect is located approximately 1 kilometer southeast of Golden Saddle. Two holes at the Arc Zone in 2008 identified intercepted gold mineralization, hole WD-17, returned 1.47 g/t Au over 29 meters from 100 meters below surface and is located 600 meters from WD-14, which returned 1.18 g/t Au over 28.5 meters starting at surface. The Arc zone soil anomaly is characterized by gold values exceeding 80 ppb, extends over a distance of two kilometers and is a separate target from Golden Saddle. Mineralization intersected in holes WD-14 and WD-17 is open for expansion in all directions.

Golden Saddle and Arc were discovered during the Company's 2008 drill program. Both gold zones are potentially amenable to open pit mining. It is the Company's intent, subject to results of the Phase 1 drill program, to continue drilling through the summer of 2009 with the objective of estimating a NI 43 - 101 compliant Resource during Q4/09.

The Golden Saddle, Arc, and multiple other untested zones at the 100 square kilometer White Property are within an 8 kilometer by 4 kilometer anomalous area. Additional mapping, sampling and mechanical trenching will be completed at other targets on the Property, with possible follow-up diamond drilling during the summer. Maps and descriptions of the White Gold Property can be reviewed at www.underworldresources.com.

Quality Assurance

The 2008 and 2009 Exploration Programs at White Gold have been directed by Adrian Fleming, M.A.I.G, RPGeo, M.Aus.I.M.M., President of Underworld Resources and a Qualified Person as defined by NI43-101. Core drilling services for 2009 Program will be performed by Peak Exploration of Courtenay, B.C. Drill cores will be cut in half using a diamond saw, with one-half placed in sealed bags, and delivered to ALS-Chemex Labs facility in Vancouver, B.C. A sample quality control/quality assurance program using standards and blanks, as well as check assaying will be implemented. Mr. Fleming prepared, and approved the content of this release.

Underworld Resources is a well-structured junior exploration company targeting precious metals in the Americas.

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.
