Diamondex Resources Ltd.: Brodeur Project Update

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 12, 2007) - Diamondex Resources Ltd. (TSX VENTURE:DSP) ("Diamondex") is pleased to announce that the field component of the 2007 exploration program for the Brodeur Project has now been completed (See www.diamondex.net for project location and details).

The exploration program consisted of ground geophysics, till and stream sediment sampling and diamond drilling. A total of 700 line kilometres of ground magnetics were completed over 18 ground grids that encompassed an area of approximately 20 square kilometres. The exploration area includes the Tuwawi and Nanuk kimberlites as well as the Kuuriaq kimberlite corridor.

A total of 512 till and stream sediment samples were collected over the project area and are currently being shipped to Overburden Drill Management Ltd. in Ottawa for processing. The resulting heavy mineral concentrates will be picked for kimberlite indicator minerals by Diamondex's mineralogical staff.

A recently completed 2,200 metre diamond drill program was undertaken to better define the geometry of the Tuwawi kimberlite body and to extract sufficient kimberlite to allow for estimations of potential diamond grades and quality. A total of 3,110 kilograms of hypabyssal, fine to medium grained macrocrystic kimberlite was collected from 12 tests that intercepted Tuwawi. A drill hole designed to test the Tuwawi Deep target which was outlined by ground magnetic and gravity surveys was abandoned due to drilling difficulties and will be re-tested during the 2008 drill program.

In addition to the Tuwawi drill program, 14 tests were completed over the Nanuk and Kuuriaq target areas with kimberlite intercepted in nine of the holes (preliminary models will be available on the website in the near future).

Kimberlite from all drill targets, a total of 3,325 kilograms, has been delivered to Kennecott Canada's Exploration Inc's. (KCEI) Processing Laboratory in Thunder Bay, Ontario, for caustic fusion processing and diamond recovery. Results are expected by year end.

With 2007 project expenditures of $2.3 million ($5.5 million to date), it is expected that by the end of the fiscal year, Diamondex will have spent in excess of $6 million on the project and earned a 100% interest in the project.

David Clarke, P.Geol., MSc., Vice President of Exploration for Diamondex Resources Ltd. is a Qualified Person as defined by National Instrument 43-101 and is responsible for program design and quality control of exploration undertaken by Diamondex Resources Ltd.

The Brodeur Project is centered on the northern half of the Brodeur Peninsula of Baffin Island. Diamondex has the exclusive option to earn a 100% interest in the property, subject to an underlying Property Acquisition Agreement with Kennecott Canada Exploration Inc. The property comprises 425,289 acres covering 165 claims and hosts three known diamond bearing kimberlite bodies: Tuwawi, Nanuk, and Kuuriaq.
