Diamondex Resources Ltd.: Brodeur Project Update

Marketwired Canada
Diamondex Resources Ltd. (TSX VENTURE:DSP) ("Diamondex") is pleased to provide
diamond results from the caustic fusion of 3,068 kg of kimberlite recovered
during the core drilling program completed within the Tuwawi, Nanuk and Kuuriaq
target areas in 2007 at Diamondex's Brodeur project in Nunavut (see
www.diamondex.net for project location, drill plan and photos).
Twelve inclined and vertically oriented tests totaling 1,336 meters of diamond
drilling were undertaken to better define the geometry of the Tuwawi kimberlite
body. In all, a total of 2,873 kg (dry laboratory weight) of hypabyssal, fine to
medium grained macrocrystic kimberlite was analyzed for microdiamonds by the
caustic fusion process. Table 1 lists the sieve data for the 592 diamonds
recovered.

The largest stone recovered, 0.237 carat, is described as an intact transparent
dodecahedron with dimensions of 4.35 x 4.10 x 2.10 mm. The second largest stone
is a fragmented transparent dodecahedron with dimensions of 4.24 x 2.60 x 1.70
mm and a weight of 0.144 carat.
Modeling of the microdiamond results indicates that the stone size versus the
cumulative grade plot compares favorably with the results Kennecott Canada
Exploration Inc. (KCEI) reported from their 1,521 kg sample from the Tuwawi
kimberlite in 2003 and 2004 (18.66 cpht vs. 20.68 cpht). However, it is also
significant that the statistical curves indicate a larger sample would yield
larger diamonds as well as a higher grade.
At the Nanuk kimberlite cluster, 1,600 metres west-southwest of Tuwawi, six
geophysical targets distributed over an area of 2.9 hectares were tested by
eight drill holes. Four separate kimberlite bodies were intersected, with 78 kg
of kimberlite collected for microdiamond analysis (Table 2). Previous sampling
of kimberlite float from Nanuk had indicated relatively high microdiamond
contents (see news release dated May 30, 2007).

Kuuriaq is a 4 km long array of kimberlite occurrences extending from an area
about 2.8 km west of the Tuwawi kimberlite to the Katigia kimberlite dyke, 2 km
due north of Tuwawi. Near the southwest end of Kuuriaq, kimberlite was
discovered by three drillholes at two separate targets, but fine-grained
kimberlite from these occurrences is weakly diamondiferous to barren (Table 3).
In the northeast portion of the Kuuriaq corridor, the Katigia kimberlite dyke
was represented by a previously untested magnetic lineament. Drilling
successfully intersected kimberlite on this magnetic lineament at two locations
separated by 260 metres and about 500 metres northeast of the Katigia outcrop
area (Table 4).

Kimberlite cores sampled in the field were securely contained and shipped to
Kennecott's Mineral Processing Laboratory in Thunder Bay, Ontario, for caustic
fusion processing and diamond recovery. KCEI's laboratory is accredited to
ISO/IEC 17025 for specific registered tests. The samples were processed
according to registered methods and standard operating procedures.
Exploration Summary and Future Plans
The 2007 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.
In addition to the ground geophysics, a total of 512 till and stream sediment
samples were collected over the project area. Overburden Drill Management Ltd.
of Ottawa, Ontario has processed and delivered over 80% of the heavy mineral
concentrates to Diamondex's mineralogical staff for kimberlite indicator mineral
picking. It is expected that all samples will be picked within the next 6 weeks.
Diamondex is currently planning its 2008 and 2009 field programs for the
property. Priority initiatives being evaluated include:
- Contemplation of a mini bulk sample for the Tuwawi kimberlite
- Drill testing of the Tuwawi Deep target
- Drill testing of high priority geophysical anomalies located outside of the
known kimberlite corridors
- Follow-up till sampling, on the eastern half of the property, to locate
sources of kimberlite indicator mineral anomalies
The Brodeur Project is centered on the northern half of the Brodeur Peninsula of
Baffin Island. Diamondex is earning a 100% interest in the property, subject to
an underlying Property Acquisition Agreement with Kennecott Canada Exploration
Inc. The property comprises 211,216 acres covering 82 claims and hosts three
known diamond bearing kimberlite bodies: Tuwawi, Nanuk, and Kuuriaq.
