Excalibur Resources Conducts Preliminary Grab Sample Program at Delamar North Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 13, 2007) - Excalibur Resources Ltd. (CNQ:EXBR)(FRANKFURT WKN: A0MMDH) -

The Company is pleased to announce that, in a preliminary work program, 15 additional grab samples have been collected from the Stinger Claim Block that forms the Company's Delamar North Property. During the program, an extension to the vein system, approximately 240 meters to the northwest and along the north-northwest trending fault that overlays the Stinger Claims, was discovered. In addition, two more prospect pits were found. There are no known historical records available on these prospect pits, nor on the first mineshaft discovered on the Property in 2003.

This sampling program was undertaken prior to and in preparation for a ground exploration program later this summer. The ground work will include the layout of a grid system, soil and rock sampling, a detailed analysis of the shaft area and a geophysics program to determine prospective drilling targets. Assay results are pending and will be announced when available.

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. The Corporation is aggressively investigating the potential acquisition of other precious metal targets within the United States, Canada and northern Europe. The Corporation intends to acquire a portfolio of properties through project acquisitions, joint ventures and alliances.
