Diamondex Resources Ltd. TSX VENTURE: DSP

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 11, 2009) - Diamondex Resources Ltd. (TSX VENTURE:DSP) (the "Company") announces results from diamond drilling of eight priority geophysical targets on its 90% owned Nickel Bay Property in the James Bay Lowlands area of northern Ontario. The targets are located inside Area 1, a subset of roughly three contiguous claim blocks, within the 414,385 acre property. See www.diamondex.net for project location and description.

All of the tests, which were collared at an average of 12 kilometres apart, intercepted sulphide mineralization, primarily comprised of pyrrohotite and pyrite as well as visible chalcopyrite and sphalerite. Individual drill intercept widths of massive and semi-massive sulphide mineralization ranged from approximately 2 to 50 metres. Analytical results from 139 samples from these zones were submitted to Accurassay Laboratories of Thunder Bay, Ontario. Strongly anomalous copper (0.14%) and zinc (0.32%) assays were returned. No significant nickel values were reported.

Several of the tests intersected intervals of well developed hydrothermal alteration, over widths of up to 40 metres, which contained varying amounts of sericite, carbonate, and silica alteration along with quartz veins and brecciation developed within the altered sections. Whole rock geochemistry from cores collected above and below the altered zones indicates that the tested areas are dominated by volcanics of tholeiitic and calc alkaline basalt affinity. These suites of rock types can be associated with the upper (younger) successions of the Archean greenstone belts of the Superior craton (and cratons throughout the world) and can host volcanogenic massive sulphide (VMS) deposits as well as lode gold mineralization.

This initial drill program within a relatively unexplored greenstone belt successfully demonstrated Area 1's potential to host VMS and lode gold deposits. The discovery of well developed hydrothermally altered zones within a package of prospective volcanic rocks that returned anomalous copper and zinc values as well as gold assays up to 0.6 grams/tonne is highly encouraging. In light of consistently anomalous gold values within some of these intervals, the Company is currently sampling additional cores from within the hydrothermal zones and the assay results will be reported as they are received. The Company is confident that follow-up drilling of off-hole conductors located by subsequent Borehole Pulse electromagnetic surveys as well as the testing of the remaining priority geophysical anomalies within Area 1 is warranted. A follow-up drill program is currently being planned to further test additional geophysical targets on the property.

Area 1 represents less than 20% of the Nickel Bay property. In 2008 approximately 13,000 line-kilometres of versatile time domain electromagnetic ("VTEM") surveys were flown over the entire property identifying 78 priority conductors with minimum conductance values greater than 100 siemens. The resulting targets are characterized as strong conductors hosted within volcano-sedimentary stratigraphy similar to that which hosts Noront's Double Eagle nickel deposit and Spider-KWG's McFauld's Lake VMS deposits.

The Company is one of the largest property holders in the area, and has established a leading position in what could be one of Canada's last unexplored volcanic belts with demonstrated economic potential.
