Underworld Intersects 9.2 g/t Au Over 31.2 Meters at White Gold Property

  Underworld Resources Inc. (TSX VENTURE: UW) is pleased to announce that results have been received from an additional four holes from the Golden Saddle Zone and three additional holes from the Arc Zone at the White Gold Property, Yukon. At Golden Saddle, the highest grade gold mineralization to date was encountered along strike to the northeast in hole WD09-47 (75 metre step-out). Highlights include:

- WD09-43: 106.0 meters averaging 2.29 g/t Au

- WD09-44: 56.1 meters averaging 3.91 g/t Au

- WD09-47: 31.2 meters averaging 9.20 g/t Au

Golden Saddle

At Golden Saddle, WD09-47 returned 9.20 g/t Au over 31.2 meters, including 29.82 g/t Au over 5.82 meters and 19.77 g/t Au over 4.0 meters. WD09-47 is located 75 meters along strike to the northeast from WD09-44 which returned 3.91 g/t Au over 56.1 meters. WD09-47 intersected a series of thick quartz veins hosting visible gold mineralization. The veins occur along the same north dipping structure as previous thick intercepts to the west, however the host rock changes from an augen gneiss to amphibolite gneiss. It is interpreted that this rock change focuses the gold mineralization into a tapered higher grade structure. The current drilling at Golden Saddle is targeting extensions to the higher grade gold mineralization down-dip and along strike to the northeast from WD09-47.

WD09-44 and 45 were drilled from the same setup, with mineralization hosted with metamorphosed intrusive rocks. WD09-44 encountered 56.1 meters averaging 3.91 g/t Au, including 32.5 meters averaging 5.58 g/t Au. WD09-45 tested 70 meters up-dip from WD09-44, intersecting 2.1 g/t Au over 13.3 meters within a less favourable host rock.

Infill hole WD09-43 returned 2.29 g/t Au over 106.0 meters, and demonstrates excellent continuity between previously reported holes WD09-31, which returned 3.4 g/t Au over 104 meters to the southwest, and WD09-38, which intersected 0.95 g/t Au over 153.0 meters to the northeast. WD09-38 includes higher grade upper and lower intervals, including over 3.1 g/t Au over 17.2 meters and 4.1 g/t Au over 16.0 meters.

Assays are pending for 10 additional drill holes at Golden Saddle including stepouts to the north, south and east.

Arc Zone

At the Arc Zone, located two kilometers southeast of Golden Saddle, assays for the final three of five holes drilled in the 2009 Phase 1 drill campaign have been received. WD09-40 and 42 are located 200 and 400 meters respectively southeast from drill hole WD08-14 which was completed in 2008. These holes encountered narrower zones of the quartzite hosted mineralization. Drill hole WD09-42 was located north of WD09-37 and 39 at the Arc to test for extension to the north and a possible link between Arc Zone and Golden Saddle. This hole was drilled where the host quartzite has been fault offset to the south.

The mineralization at Golden Saddle is preferentially hosted within a deformed intrusive unit (augen gneiss), schists and amphibolites. Gold mineralization is associated with quartz breccias, veins and stockworks, as well as silica, sericite, K-feldspar, and ankerite alteration. Sulphide mineralization is dominated by disseminated and stockwork pyrite, with local visible gold, chalcopyrite, galena and molybdenite.

Two drills are currently working on the 6,000 meter 2009 Phase 2 program on the Property. During 2009, 35 drill holes have been completed to date on the Property. The current drilling is focused on extending the Golden Saddle and Arc Zones. Drilling is currently testing the western extension to Arc Zone, as well as other targets on the property such as Minneapolis Creek and Donahue. A third drill rig is currently being mobilized to the Property.

Drill hole location plans and cross sections from the Golden Saddle and Arc Zones are available at www.underworldresources.com.

Exploration work, including mechanical trenching, is continuing on several other targets at the White Gold Property prior to drill testing during the summer of 2009. Underworld intends to complete a NI43-101 Resource Estimate on the Arc and Golden Saddle Zones in Q4/09.

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, standard and blank samples are submitted, with drill core sawn in half and shipped in sealed bags to ALS Chemex Laboratories in Vancouver.

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.
