Pacifica Resources Extends Limits of High-grade Mineralization at XY
Vancouver, British Columbia CANADA, March 13, 2007 /FSC/ - Pacifica Resources Ltd. (PAX - TSX Venture), is pleased to provide an update on drill hole results in the XY Zone including both the open-pit area and drilling both along strike and down-plunge of the previously defined underground Inferred resource. Location of the new drill holes and detailed drill plan maps are available at www.pacifica-resources.com. These holes complete the results from the 2006 drilling.
XY Central Zone - Open Pit
Drill hole XY-136 is the final drill hole from the XY Central Zone open pit target to be reported from the 2006 drilling program. It should be noted that the depth of the intercept in XY-136 is at the transition between the bottom elevation of the open pit and that of the high grade underground resource. XY-136 is also a transition drill hole from deposit average grade to higher grade mineralization as demonstrated by the presence of elevated lead grade. In all five areas known to possess the potential for high grade underground resource targets, the transition to high grade zinc-lead mineralization is denoted by lead grades above three percent over at least several metres of the Active Member.

XY Underground Resource
The final drill hole from the high grade underground resource area from 2006 drilling activities is XY-149, which intersected a true thickness of 4.03 metres of well mineralized Active Member, thereby demonstrating the predictable continuity of the high-grade zinc-lead mineralization intersected in drill holes XY-111, XY-112, XY-124, XY-133, XY-138, XY-141, and XY-150. The continuing success in intercepting the high grade underground resource supports the potential for continued expansion of the higher grade mineralization in 2007 with continued deep drilling. It should be noted that all of these high grade intercepts are above the elevation of the floor of Don Valley and are therefore easily accessible with horizontal drifting for development.

Drill hole XY-149 is located 310 metres northwest of XY-124 and 230 metres northwest of XY-133 and 550 metres northwest of XY-116 that previously intersected high grade mineralization down-dip of the Inferred resources in the proposed open pit (see August 31, September 26, and October 10, 2006 news releases). An Inferred resource of 8,100,000 tonnes (8,900,000 short tons) grading 10.6% zinc and 5.5% lead was defined by Placer in 1981 and reviewed and reported upon in the June 2005 NI-43-101 compliant report prepared by Mr. Al Burgoyne and filed on www.sedar.com (note that this resource estimate predates NI-43-101 and should not be relied upon).
The continuing success in intercepting the high grade underground resource supports the potential for expansion of the higher grade mineralization in 2007 with continued deep drilling. It should be noted that all of these high grade intercepts are above the elevation of the floor of Don Valley and are therefore easily accessible with horizontal drifting for development.
The Selwyn Project exploration program is being reviewed by Vice President Exploration, Mr. Jason Dunning, M.Sc., P.Geo. The onsite activities for the Selwyn Project are directed by Exploration Manager, John J. O'Donnell, P.Geo. Both Mr. Dunning and Mr. O'Donnell are Qualified Persons within the meaning of National Instrument 43-101. All assay data has been through internal validation of quality assurance and quality control. Pacifica has established a sampling and assay control program with blind insertion of assay blanks, standards and duplicates for the Selwyn Project; however, it should be noted that there is also a quality control and quality assurance program in place at both ACME Analytical Laboratories Ltd. ("ACME") and ALS Chemex that includes blanks, duplicates and standards. At ACME, silver and base metal analyses are conducted by a 17-element, four-acid digestion, ore-grade ICP-AES technique. At ALS Chemex, silver and base metal analyses are conducted by a 25-element, four-acid digestion, ICP-AES technique with overlimit protocols for zinc, lead, copper, antimony, arsenic, and barium conducted by an ore-grade aqua-regia digestion with an instrument finish (ALS-Chemex).
Note that all discussion of NI-43-101 compliant Indicated and Inferred mineral resources are referenced in the March 2006 NI 43-101 report for Howard's Pass. In reviewing historical resources, all discussion of Indicated mineral resources that predate introduction of NI 43-101 should be considered as Inferred mineral resources. All historical Inferred mineral resources that predate NI 43-101 should be considered as areas of mineral potential requiring further definition through drilling. Historical mineral resources are referenced in the June 2005 NI 43-101 report for Howard's Pass. Copies of the reports can be viewed at www.sedar.com.
Pacifica's main focus is the exploration of its Selwyn Project in eastern Yukon and Northwest Territories. The Selwyn Project hosts very large tonnages of zinc-lead mineralization. The known deposits have the potential for large scale production of zinc and lead, at a time when World's zinc mine supply is in deficit and there are few new zinc-lead mines under development.
This press release may contain forward-looking statements based on assumptions and judgments of management regarding future events or results that may prove to be inaccurate as a result of exploration and other risk factors beyond its control and actual results may differ materially from the expected results. Additional drilling is required to confirm the potential of the new discovery areas and expansions of the current resource areas. Furthermore, there is no assurance that the resources being defined can be developed as an economically attractive mine, and there are many uncertainties associated with permitting and other factors that could delay such development.
THE TSX VENTURE EXCHANGE HAS NOT REVIEWED AND DOES NOT ACCEPT RESPONSIBILITY FOR THE ADEQUACY OF THIS NEWS RELEASE.
