UNDERWORLD INTERSECTS 3.2 G/T AU OVER 44.5 METERS AT WHITE GOLD PROPERTY

Underworld Resources Inc. has received results from nine additional holes drilled during the phase 1 campaign at the White Gold property. At Golden Saddle, extensions to gold mineralization down dip and along strike to the northeast have been confirmed. Two additional holes at the Arc zone demonstrate continuity of mineralization discovered in 2008. Drill hole location plans and cross-sections are available on the company’s website. The table provides further details.

Golden Saddle

Highlight of the Golden Saddle results is WD09-32 which returned 3.16 grams per tonne gold over 44.5 metres from 179.5 metres and extends the Golden Saddle upper zone farther down dip. WD09-32 is located 60 metres down dip from WD08-21, which returned 3.2 g/t Au over 50.7 metres.

WD09-34, which returned 1.4 g/t Au over 29.50 metres, demonstrates extension of the mineralized zone farther to the northeast. WD09-38 intersected 0.95 g/t Au over 153.0 metres, including higher-grade upper and lower intervals, including over 3.1 g/t Au over 17.2 metres and 4.1 g/t Au over 16.0 metres. WD09-38 intersected the Golden Saddle zone 60 metres up dip from WD09-34.

WD09-30 was drilled up dip from the same collar location as WD09-31, which intersected 3.4 g/t Au over 104.0 metres. WD09-30 returned 0.6 g/t Au over 70.9 metres, including 2.1 g/t Au over seven metres, but the zone was truncated by an altered and sheared ultramafic unit or dike, which is interpreted to be a poor host rock to the gold mineralization within the Golden Saddle zone.

Two drills are currently working on the 6,000-metre 2009 phase 2 program. Assays are pending for four additional holes at Golden Saddle including WD09-44, 45 and 47, which tested for further extensions to the northeast spanning an additional 120 metres of strike length.

Arc zone

At the Arc zone, located two kilometres southeast of Golden Saddle, assays for two of five holes drilled in the 2009 phase 1 drill campaign have been received. WD09-37 and 39 are located between holes WD08-14 and 17 drilled in 2008. WD09-37 returned 1.32 g/t Au over 31.5 metres from 123.5 metres while WD09-39 returned 1.51 g/t Au over 14.5 metres from 78 metres. These holes complement WD08-14 and WD08-17 and confirm continuity of mineralization over a strike distance of 600 metres. Two of the three additional holes at Arc with assays pending were tested extensions to the zone farther south of hole WD08-14, while hole WD09-42 was located north of WD09-37 and 39 to test for extension to the north and a possible link between Arc zone and Golden Saddle.

 The upper zone mineralization at Golden Saddle is preferentially hosted within a deformed intrusive unit (augen gneiss), and to a lesser degree within 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 and molybdenite.

The 2009 phase 2 drill program is continuing with two drills. Fourteen holes have been completed at Golden Saddle in 2009 with holes 47 and 48 in progress. The current focus of drilling is to extend the Golden Saddle mineralization. Additional step-out drill holes are being planned in all directions.

Upon receipt of assays from the remaining three Arc zone holes drilled in the 2009 phase 1 program, additional infill and step-out drill holes will be planned.

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 National Instrument 43-101 resource estimate on the Arc and Golden Saddle zones in the third quarter of 2009.

Quality assurance

Underworld has implemented a rigorous quality-assurance/quality-control 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. The continuing 2009 exploration program is directed by Adrian Fleming, MAIG, RPGeo, MAusIMM, 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 INTERSECTS NEW GOLD-SILVER RICH DEEP ZONE BELOW GOLDEN SADDLE, WHITE GOLD PROPERTY, YUKON

Underworld Resources Inc.’s results have been received from a new, deep gold-silver rich zone at the White gold property, Yukon Territory. Hole WD09-31 returned 10.5 metres averaging 4.8 grams per tonne Au and 38.2 g/t Ag starting at 401.5 metres within a breccia zone underlying the Golden Saddle zone. Previously released results from the overlying zone at Golden Saddle include:

WD09-28 — 1.84 g/t Au over 102.5 metres from 105 to 207.5 metres;

WD09-29 — 3.94 g/t Au over 59.9 metres from 146.1 to 206.0 metres;

WD09-31 — 3.59 g/t Au over 98.3 metres from 105.7 to 204.0 metres.

The deep breccia zone within WD09-31 occurs from 401.5 to 412.0 metres and includes 9.40 g/t Au and 73.3 g/t Ag over 3.4 metres, underlying the upper zone in this hole. WD09-31 was lost at 414.8 metres due to depth limits of the diamond drills currently in use at Golden Saddle. Underworld is mobilizing a more powerful drill rig to the White gold property with capacity to test this new zone to greater depth.

Mineralization in the deep hole 31 breccia zone is hosted in a milled hydrothermal breccia with interstitial pyrite and specular hematite. The discovery of this zone suggests the potential for stacked mineralized structures within Golden Saddle. Furthermore, the Ag/Au ratios within the upper Golden Saddle zone are typically greater than 1:3 whereas the Ag/Au ratios in the lower breccia Golden Saddle zone is 8:1. This type of mineral zonation is often associated with intrusion-related gold deposits is suggestive and suggests that there may be an intrusive source to mineralization at depth.

Two diamond drills are currently on the White gold property, and have completed nine holes at the Golden Saddle zone, and five holes at Arc zone (located two kilometres southeast of Golden Saddle). Results from these drill holes will be released following closure of the company’s pending financings.

UNDERWORLD INTERSECTS 104.0 METERS OF 3.4 G/T AU AT GOLDEN SADDLE ZONE, WHITE GOLD PROPERTY, YUKON

Underworld Resources Inc. is releasing assay results from the first three holes from the 2009 drilling program from the Golden Saddle zone at the White Gold property. Significant thicknesses of gold mineralization within an interpreted shallow-dipping zone were encountered in all holes. Results are as follows:

WD09-28: 1.84 grams per tonne gold over 102.5 metres from 105 to 207.5 metres;
WD09-29: 3.89 grams per tonne gold over 60.5 metres from 145.5 to 206 metres;
WD09-31: 3.39 grams per tonne gold over 104.0 metres from 100 to 204 metres.

These holes were completed in a fence of four, drilled at the Golden Saddle zone, west of hole WD08-21 that returned 3.1 grams per tonne gold over 50.7 metres. The objective of these initial holes was to test for the continuity of mineralization and to test the mineralization to depth, below hole WD08-21 that bottomed in alteration and in mineralization.

Complete results from the three initial holes are provided in the table. It is currently interpreted that the mineralization is shallow dipping, however further assay results and additional drilling is required before reliably estimating true thickness. The four holes on this section span approximately 120 metres of down-dip extent, with assays pending for WD09-30. Additional assays are also pending from above and below the zone WD09-31.

Gold mineralization at the Golden Saddle zone is associated with strongly silica, albite and serecite-altered felsic schists associated with hydrothermal brecciation and quartz-pyrite stockwork and veinlettes. Gold grade is consistent throughout the mineralized interval, with higher-grade zones near the hangingwall and footwall. The mineralization encountered in holes WD09-28, WD09-29 and WD09-31 do not correlate with WD08-20, which is located farther southeast on the same section line. Hole WD08-20 collared in mineralization, encountering 27.7 metres averaging 1.87 grams per tonne gold; and may be a separate, shallow zone.

Two diamond drills are currently on the 169-square-kilometre White Gold property, and have completed to-date nine holes at the Golden Saddle zone, and one hole at Arc zone (located two kilometres southeast of Golden Saddle). An additional five holes are planned for the current phase 1 4,000-metre drill program, in addition to mapping, trenching and sampling on multiple other targets on the property. Further assays will be released upon receipt. A plan showing holes drilled to date, in progress and planned for Golden Saddle can be seen on the company’s website. Once additional holes are completed at the Arc zone a location map will be posted on the website.
