Pacifica Resources Drilling Extends Limits of High-grade Mineralization at XY
Vancouver, British Columbia CANADA, October 30, 2006 /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 (see August 31 and September 26, 2006 news releases). Results of drilling of other zones will be released shortly.
The Selwyn Project hosts the world-class Howard's Pass SEDEX zinc-lead deposits. Drilling continues with 6-drill rigs on known mineralized zones on the 96 square kilometres of Howard's Pass Joint Venture ("HPJV") claims under purchase agreement and new target evaluation on the more than 209 square kilometres of wholly owned mineral claims (Pacifica Claims). Location of the new zones and detailed drill plan maps are available at www.pacifica-resources.com.
Highlights
* Definition drilling continues to expand along strike the underground Inferred mineral resource with XY-141 intersecting 24.72 metres true thickness grading 8.64% zinc and 2.26% lead that includes 2.85 metres grading 26.56% zinc and 4.91% lead.
* Infill drilling continues to show potential for higher zinc and lead grades within the open-pit target with XY-142 intersecting 14.25 metres true thickness grading 10.03% zinc and 2.75% lead that includes 1.49 metres grading 44.90% zinc and 10.42% lead or 55.32% combined zinc-lead.
* 177 drill holes have been completed for a total of 39,092.1 metres.
Extension of XY Underground Resource
Drill hole XY-141 intersected a true thickness of 24.72 metres of well mineralized Active Member demonstrating the continuation of the high-grade zinc-lead mineralization intersected in drill holes XY-111, XY-112, XY-124, and XY-133 and the potential expansion of the high grade underground Inferred resource. Drilling continues down dip and along strike of the new high grade drill hole intercepts (see September 26 and October 10, 2006 news releases). All the 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-141 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 resource beneath 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 reviewed and reported in a 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). Drilling is continuing with four drills testing the down dip and lateral extension of the area of high grade mineralization in XY Central zone.
XY Central Zone - Open Pit
Recent drill results from the XY Central zone include intervals of high-grade zinc-lead mineralization similar to that encountered in the underground Inferred mineral resource in the northwest part of the XY zone. Of interest is drill hole XY-142 that intersected 14.25 metre true thickness of mineralized zinc-lead Active Member. This drill hole is located at a shallow depth and outside of the historical resource area utilized in the March 2006 resource report. Additional definition drilling is continuing in this area to expand resources, as the deposit remains open along strike to the northwest and down-dip.

Drilling is continuing in the Anniv and XY areas. Follow-up of the DON-4 drill hole discovery in 2005 is underway with two drills. With the onset of winter conditions, the Anniv camp is being shut down and two of the drills are shut down and being stored for the winter. Anniv camp facilities are also being transferred to the new camp and air strip under construction in Don Valley.
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.
