Excalibur Resources Ltd. Prepares Exploration Program for the Former Silver King Mine Property, Nelson, British Columbia, Canada

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 13, 2007) - Excalibur Resources Ltd. (the "Company") (CNQ:EXBR)(FRANKFURT WKN:A0MMDH) is pleased to announce that Dr. Hamid Mumin Ph.D., P.Eng., P.Geo., an independent consultant to the Company, has prepared a report entitled "Exploration and Development Potential of the Former Silver King Mine Property, Nelson British Columbia, Canada". The report is intended to review, evaluate and report on the mineral potential of the Company's Silver King Mine Property located approximately seven km SSW of Nelson, British Columbia. In view of the potential for additional resources within and adjacent to existing workings and considerable potential of the remainder of the property, a systematic program of detailed surface exploration and diamond drilling is recommended for the Silver King property.

During the current winter period, the Company will continue to review and process the very large data base from past mining and exploration activity and conduct preliminary work on the property. Work will include digitization of the database in order to produce a 3-D mine model. The 3-D model will be extremely useful in assisting the exploration team to extrapolate and project mineralization trends at depth. In addition, the Company will conduct mineralogical and geochemical investigations of the Silver King hosted hydrothermally altered and mineralized rocks collected earlier this year. The mineralogical work will include thin section analysis and accompanying photomicrographs, electron microprobe analysis including whole rock and trace element geochemical analysis.

The Company intends to conduct an early summer program to include line cutting, detailed geological mapping, a geophysical survey and a Phase I drilling program. The Phase I, first objective drill program is designed to confirm and extend near surface resources along the Silver King Vein. It is recommended that a minimum of 17 diamond drill-holes representing approximately 1,600 meters (5,200 ft) be conducted. A Phase I, second objective of nine diamond drill-holes will explore near surface parallel and cross-cutting structures and previously identified geochemical and geophysical anomalies.

The former Silver King Mine produced approximately 4.4 million ounces of silver (approx. 19.8 oz/t Ag), 15 million lbs. of copper (Approx. 3.3% Cu), 31,000 lbs. of lead, 7,400 lbs. of zinc and 280 oz. of gold from approximately 222,000 tons of direct smelting ore. Most mining occurred between 1889 and 1913. No recorded production took place after 1943.

The contents of Dr. Mumin's Report will be available in its entirety for review on the Company's website, www.excaliburresources.ca.

Excalibur Resources Ltd. is a junior exploration mining company focused on the discovery, development and mining of economically viable precious and base metal mineral resources.
