Darnley Bay Resources Completes 2010 Base Metals Drill Program

TORONTO, ONTARIO--(Marketwire - Nov. 23, 2010) - Darnley Bay Resources Limited ("Darnley Bay") (TSX VENTURE:DBL) has completed the 2010 phase of its drilling program at the Paulatuk Property in the Northwest Territories. The last hole was G-09-01, drilled on a high priority gravity and magnetic target within the Darnley Bay Gravity Anomaly. It penetrated 158.5 m of glacial overburden and continued to a depth of 242 m in bedrock, consisting of blocky karsted dolomite with clay seams. Drilling to date has not explained the Anomaly. Deteriorating weather conditions prevented further drilling after November 20. The drill has been left at the target site for resumption of drilling in early 2011. The drill camp remains on site. Ground geophysical surveys (gravity, electromagnetic and magnetic) for 2010 were completed in late October over all selected targets.

Samples of the bedrock drill core from holes M-07-01 (see news release of October 20, 2010) and G-09-01 are being prepared for laboratory analysis. Darnley Bay will assess the results of its 2010 drilling, geophysics and geological mapping in preparation for drilling in 2011. It remains committed to determining the source of the Darnley Bay Anomaly and locating associated mineral deposits. Darnley Bay has funds to continue the base metals drill program in 2011, and will consider additional financing and/or partnerships for an expanded program.

As indicated in the news release issued by Diadem Resources Ltd. on November 15, 2010, Darnley Bay and Diadem are planning an expanded drill program for diamonds in 2011.

Mr. Reford presented a poster paper at the Yellowknife Geoscience Forum from November 16 to18. It is available for download from www.darnleybay.com, highlighting results from the 2010 field work.
