Excalibur Resources Ltd.: Minera Catanava Project Receives SEMARNAT Permit Approval

TORONTO, ONTARIO--(Marketwire - Nov. 25, 2011) - Excalibur Resources Ltd. (the "Company") (CNSX:XBR)(FRANKFURT WKN:A0MMDH) reports that its 49% subsidiary, Minera Catanava S.A. de C.V. ("Catanava") has received all the necessary permits required to build the plant and to go into production. The EIS application to the SEMARNAT in Zacatecas was submitted in June, was reviewed in July, followed by a site inspection in August, which lead to a request for a number of items, including a soil analysis report on the tailings area and the completion of the water permit from the National Water Commission (CNA). Tim Gallagher, Chairman of Excalibur commented, "We are extremely pleased to have achieved this major milestone. Receiving the SEMARNAT approval is the official Mexican government green light that allows Minera Catanava to proceed to the start up stage of development. This has been a tremendous amount of work and we congratulate the team in Mexico. We also expect the explosive permit shortly, but given the amount of material already on surface in the San Gil area, it is not required to start production."

Recent work at the site has been focused on the completion of the foundation in order to install the ball mill, crushers, conveyors and the recently delivered concentrators which have been sourced from www.actionmining.com.
