TORONTO, ONTARIO--(Marketwire - Sept. 8, 2010) - Darnley Bay Resources Limited ("Darnley Bay") (TSX VENTURE:DBL) and Diadem Resources Ltd. ("Diadem") (TSX VENTURE:DRL) are pleased to announce that they have completed the first phase of 2010 drilling on their 50/50 joint venture package of 33 claims on the Parry Peninsula, Northwest Territories. Of the four targets drilled, three have resulted in the discovery of new kimberlite pipes. These are in addition to the ten kimberlite pipes discovered in 2000, of which six have proven diamondiferous. The kimberlite material intersected in the 2010 drilling is being prepared for shipping to CF Mineral Research Ltd. in Kelowna BC for analysis.

Darnley Bay and Diadem are quite encouraged by the initial success of the drill program. Numerous high priority targets remain untested. The results of this first phase are being incorporated in planning for the second phase of 2010 drilling, as well as determining the targets that are better suited for drilling from frozen lakes in February-April 2011. Diadem is funding the 2010 program.

The drillholes are summarized as follows:

Coordinates are UTM 10N, NAD83.

Hole MT112-01

This hole targeted a 1.7 ha ground magnetic low of 10 nT amplitude, partially covered by a lake. It intersected 15.35 m of kimberlite, hosted in dolomite. The kimberlite intersection is described as "Dark green to black, fine grained matrix consisting of dark green ferro-magnesian minerals and 10 to 35% green partially altered olivine and peridotite fragments, some being completely talc altered. Contains numerous greenish, subrounded possible mantle derived fragments to 100 mm." The log is as follows:

Hole MT102-01

This hole targeted a 3.6 ha ground magnetic low of 325 nT amplitude, partially covered by a lake. It intersected 7.6 m of kimberlite, hosted in dolomite. The kimberlite intersection is described as "Dark gray to blackish-green, massive, fine to medium grained kimberlite (micro breccia). The mass of the kimberlite comprises dark green 1-5 mm mafics in a white clay - calcite matrix." The log is as follows:

Hole MT10-03

This hole targeted a 10.2 ha ground magnetic low of 105 nT amplitude, partially covered by a lake. It intersected 0.6 m of kimberlite, hosted in dolomite. The kimberlite intersection is described as "Dark gray to black, loose packed, sub-rounded to sub-angular wall rock and some mantle derived fragments in a fine to medium grained matrix. Fragments consist of 1 to 25 mm black mudstone and chert, gray dolomite and some greenish-gray, rarely apple green, serpentinised mantle-derived xenoliths." The log is as follows:

Hole MT10-04 was stepped back 65 m from Hole MT10-03. It did not intersect kimberlite, remaining in dolomite below the overburden. Holes MT10-01 and MT10-02 were drilled in 2000 further to the east and south respectively, and neither intersected kimberlite. The size, amplitude and shape of the magnetic anomaly indicate that additional kimberlite material should be present, and further drilling on this target will be considered in future.

In addition target MT113-01 was drilled but did not intersect kimberlite (17 m of overburden and 152 m of dolomite). This hole targeted a 2.0 ha ground magnetic low of 25 nT amplitude. The magnetic anomaly is similar in nature to those associated with the kimberlite pipes in the vicinity and its source remains unexplained. A second drill hole on this target will be considered in future.

Aurora Geosciences Ltd. is responsible for management of the drill program and the handling and logging of the core. Kimberlite intersections from drill core are secured in closed core boxes at the drill rig. The core boxes are opened at Darnley Bay's Rummy Creek field camp where qualified geologists log the core in detail for geological and geotechnical information. All cores are photographed, and systematically subjected to specific gravity and magnetic susceptibility measurements at regular intervals along the core length.

The kimberlite portions of the core are placed in tamper-proof sample bags. A small reference sample from each metre of core is retained. The bags are then placed in sealed boxes and transported by secured, express freight to the CF Mineral Research Ltd. facility in Kelowna B.C. The samples are then processed and analysed for kimberlite indicator minerals and micro-diamonds.

In addition to drilling, 66.07 line-km of ground magnetic survey data were acquired over three targets that had not been surveyed previously. The results are being evaluated for potential drill targets.

Mr. Lou Covello, P. Geo., the joint venture's Project Manager, is a Qualified Person under NI 43-101 and is responsible for the design and conduct of the programs carried out by the joint venture. Mr. Covello has reviewed this release and approves of its contents.

About Darnley Bay Resources Limited:

Darnley Bay Resources Limited was formed in 1993 to explore for and develop base metal deposits related to the 50 km x 80 km, 132 mGal Darnley Bay gravity anomaly near Paulatuk, Northwest Territories, Canada. It has discovered six diamondiferous kimberlite pipes in the same region. Darnley Bay is currently exploring and drilling for base metals on its 4,600 km² land holding. It has a 50/50 joint venture with Diadem Resources Ltd. on 33 claims that encompass ten kimberlite pipes.
