UW Underworld Resources Inc.

Underworld Resources Inc. (TSX VENTURE: UW) is pleased to announce additional results from the ongoing drill program at the White Gold Property, Yukon. To date, Underworld has completed 22,000 meters of drilling over 84 holes during the 2009 exploration program.

Highlights of the most recent assays from the Golden Saddle zone include:

---------------------------------------------------------
Hole ID    Weighted avg. grade (g/t Au)         Length (m)
---------------------------------------------------------
WD09-64                    3.13 g/t Au      100.40 meters
---------------------------------------------------------
WD09-69                    3.40 g/t Au       76.90 meters
---------------------------------------------------------
WD09-70                    3.51 g/t Au       50.03 meters
---------------------------------------------------------

Results to-date continue to demonstrate excellent continuity of near-surface gold mineralization at the Golden Saddle Zone. The deposit remains open to expansion to the east and north. Drill hole WD09-64 is a step-out hole to the northeast, and intersected 100.4 meters averaging 3.13 g/t, including 19.5 meters averaging 6.70 g/t Au. This is the northeastern most hole for which assays have been received to date, with assays pending for additional holes completed along strike and down-dip. The intercept in WD09-64 is 75 meters down-dip from WD09-56, which intersected 55.9 meters averaging 1.50 g/t Au, and 110 meters down-dip from WD09-47, which intersected 31.1 meters averaging 9.2 g/t Au. Four additional drill holes on approximately 50 meter centers have been completed down-dip from WD09-64, with assays pending.

WD09-069, which intersected 76.9 meters averaging 3.40 g/t Au, including 41.0 meters averaging 5.44 g/t Au, and WD09-70 which intersected 50.5 meters averaging 3.51 g/t Au, including 37 meters averaging 4.04 g/t Au are infill holes. Infill and step-out drilling is being completed on 50 meter intercept centers along strike and down dip. These holes demonstrate the excellent continuity of grade and thickness at Golden Saddle.

The objective of the current drilling at Golden Saddle is to continue to expand mineralization along strike and down-dip, and to complete a NI 43-101 compliant resource estimate. The Company is targeting near-surface mineralization potentially amenable to open pit mining, as well as deeper extensions potentially amenable to bulk underground mining methods. During 2009, 54 holes have been completed at the Golden Saddle Zone, with assays currently pending for 21 holes.

Most recent drill results include:

Infill and step-out drilling has been completed on 100 meter centers at the Arc Zone, located about 1,000 meters south of Golden Saddle. At the Arc Zone, 19 holes have been completed to-date, with assays pending for an additional 10 holes. Drill holes WD09-57, 58, 65, and 67 have extended the Arc zone to the West-Southwest of WD08-17 (29.0 meters averaging 1.47 g/t Au). Underworld has completed four regional holes at Minneapolis Ridge, and three regional holes have been completed at the Donahue Zone. Drill hole DN09-01 at the Donahue target, located 2,500 meters south of Golden Saddle encountered anomalous, near surface gold mineralization within soil, rock grab, and trench samples, similar in style to the Golden Saddle. Assays for two additional holes at Donahue are currently pending.

Underworld is currently drilling regional targets at the South Donahue and McKinnon showings, located four and six kilometers southeast of Golden Saddle, respectively. Three drill rigs are currently in use on the project and it is anticipated that a total of 25,000 meters of core drilling in approximately 115 drill holes will be completed during the 2009 program. A complete table of assay results from the 2009 White Gold Drilling Program, as well as cross-sections, and drill plan maps will be available shortly at www.underworldresources.com.

Intrusive-related gold mineralization at the Golden Saddle Zone is preferentially hosted within metamorphosed felsic intrusive units, as well as felsic and mafic metavolcanic rocks. Gold mineralization is associated with quartz veins, stockwork and breccia zones, as well as pyrite veinlettes and disseminations. The alteration assemblage includes pervasive K-spar, carbonate, sericite and silicification. The main mineralized zone at Golden Saddle strikes to the northeast, with a gentle to moderate dip to the northwest. Mineralization remains open to expansion along strike to the northeast and at depth.

Quality Assurance

Underworld has implemented a rigorous QA/QC program at the White Gold Property using best industry practice. Elements of the program include: chain of custody of samples, insertion of standard and blank samples, and check assays. Drill core is sawn in half and shipped in sealed bags to ALS Chemex Laboratories in Vancouver, B.C. Check assays are completed by Acme Laboratories, Vancouver.

The ongoing 2009 Exploration Program is 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 NI 43-101. Mr. Fleming prepared, and approves of the content of this release.

Underworld Resources is a well-structured junior exploration company focused on expanding its new gold discovery in the Yukon.

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.
