PACIFICA RESOURCES ANNOUNCES SELWYN PROJECT CONTINUES GROWING WITH NEW DISCOVERY AND EXPANSION OF DON ZONE
Pacifica Resources Ltd. has released drill results from the Don Valley. The company has discovered the Don East zone. The Don East zone discovery brings to five the number of new zinc-lead Sedex zones identified by the Pacifica exploration team in 2006 in areas of highly prospective strata that prior to 2006 had not seen any diamond drilling. The Selwyn project hosts the world-class Howard's Pass Sedex zinc-lead deposits. Location of the new zones and detailed drill plan maps are available on the company website.
Highlights from drilling include:
discovery of Done East zone in a 1,350-metre step-out northwest of the most-northerly HC West zone -- drill hole Don-36 intersecting 18.62 metres of zinc-lead-mineralized active member grading 5.26 per cent zinc and 1.45 per cent lead, including 2.95 metres grading 13.18 per cent zinc and 4.91 per cent lead; and
191 drill holes have been completed in the year to date for a total of 39,809 metres.
Don East open-pit target discovery
The Don East zone was discovered through continued stratigraphic drilling in Don Valley to define the extension of the mineralized active member in the HC West zone (see Stockwatch news dated Aug. 31 and Oct. 25, 2006). The Don East discovery was made 1,350 metres along trend to the northwest of the HC West zone and 3.5 kilometres southeast of the Anniv East deposit that contains a National Instrument 43-101 inferred mineral resource of 18.38 million tonnes grading 4.46 per cent zinc and 1.28 per cent lead calculated by John Nilsson, PEng, and John O'Donnell, PGeo (see March 28, 2006, disclosure on SEDAR).
Don-36 was the first drill hole in the 3.8-kilometre untested portion of the Don Valley between the Don and HC West zones and intersected 18.62 metres true thickness of zinc-lead-mineralized active member within the open-pit target range.

Pacifica has now successfully drilled the entire 11-kilometre strike length of the Don Valley and identified four new zinc-lead zones of mineralization within an open-pit target range, adding significantly to the mineral potential of the Selwyn project. Additional drilling is planned in spring, 2007, for these new open-pit targets to expand the growing mineral potential in the Don Valley, as Brodel, HC, HC West, Don East and Don zones all remain open for expansion.
Don zone open-pit target follow-up drilling
Five drill holes have now been completed as follow-up to the 2005 discovery of the Don zone open-pit target in the Don Valley (see Stockwatch news dated Sept. 6 and Oct. 25, 2005) including Don-39 to Don-43. All five drill holes intersected zinc-lead-mineralized active member. The initial hole Don-4 intersected a 34.1-metre true thickness of zinc-lead mineralization that included two mineralized intercepts, 7.81 metres grading 7.93 per cent zinc and 1.8 per cent lead from 146.55 to 155.47 metres, and 7.13 metres grading 4.71 per cent zinc and 1.74 per cent lead from 177.36 to 185.51 metres.
Don-39 and Don-40 re-enforce the significant open-pit mineral potential of the Don zone. Both Don-39 and Don-40 were collared off of the same pad approximately 150 metres from the Don-4 discovery drill hole. Don-41, collared off of the same drill pad as the Don-4 discovery hole, confirmed the continuity of the active member by intersecting zinc-lead mineralization 80 metres down-dip within the open-pit target. The presence of several higher-grade zinc-lead bands within the active member in holes Don-39 and Don-40, combined with similar higher-grade intercepts identified in the HC West zone, provide further encouragement for development of deeper resources suitable for underground mining in Don Valley (see Stockwatch news dated Oct. 25, 2006).

The Selwyn project exploration program is being reviewed by vice-president of exploration Jason Dunning, MSc, PGeo. The on-site activities for the Selwyn project are directed by exploration manager Mr. O'Donnell, PGeo. 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. 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 National Instrument 43-101 indicated and inferred mineral resources are referenced in the March, 2006, National Instrument 43-101 report for Howard's Pass. In reviewing historical resources, all discussion of indicated mineral resources that predate introduction of National Instrument 43-101 should be considered as inferred mineral resources. All historical inferred mineral resources that predate National Instrument 43-101 should be considered as areas of mineral potential requiring further definition through drilling. Historical mineral resources are referenced in the June, 2005, National Instrument 43-101 report for Howard's Pass. Copies of the reports can be viewed on SEDAR.
We seek Safe Harbor.
