PACIFICA RESOURCES ANNOUNCES HIGH-GRADE RESULTS IN DEEP DRILLING ON DON ZONE
Pacifica Resources Ltd. is providing the following update on drill hole results from the Don valley.
The new holes have increased the area of near surface open pit mineralization for both the Don and Don East zones and reconfirmed the presence of higher-grade mineralization at depth in Don valley. Location of the new zones and detailed drill plan maps are available at the Pacifica company website.
Highlights
DON-44 intersecting 18.27 metres grading 8.94 per cent zinc and 3.1 per cent lead including 2.7 metres grading 24.21 per cent zinc and 10.61 per cent lead.
Don zone deep drill hole
Drilling in the Don zone has tested an area of 450 by 300 metres. Drill hole DON-44 is located 160 metres southwest from DON-42 and is the deepest intersection drilled to date in the Don zone and hosts a thick sequence of high-grade mineralization. The mineralization in DON-44 is the highest grade intersection outside of the XY zone where deep drilling has defined high-grade mineralization below the open pit portion of the XY deposit. DON-44 is one of several higher grade drill holes that have been intersected over the 13.5 kilometres between the Don and XY zones. The Don zone remains open to expansion along strike and at depth.

Including 318.70 322.00 3.30 10.61 24.21 34.82 2.70
The high grade intercept in DON-44 is the down dip extension of the active member in Don 41 and 42 and is 125 and 50 metres lower in elevation than those holes, respectively. DON-44 is also approximately 225 metres lower in elevation than DON-22 in the HC West zone that also hosts high grade mineralization within the active member (see news reported in Stockwatch on Oct. 25, 2006).
The intersection in DON-44 of 18.27 metres true thickness of higher grade zinc-lead mineralization, with narrower intervals of even higher grades, appears to signal a transition to higher grades at depth, similar to as seen in the XY zone and more recently in both Anniv Central and HC zones (see news reported in Stockwatch on Nov. 30, 2006) and those discussed for the Don zone (see news reported in Stockwatch on Dec. 11, 2006). Additional deep drilling is planned to test the extension of these higher grade intercepts beneath the probable depth of open pit mineralization in Don Valley and lateral continuity over the 13.5-km-long mineralized active member horizon between Don and XY zones.
Don East zone open pit target
During 2006, four drill holes were completed on the Don East zone open pit target in the Don valley. The drilling defines a strike length of 550 metres for Don East within the shallow open pit environment. DON-45 is located 400 metres northwest of the discovery drill hole DON-36 (see news reported in Stockwatch on Nov. 30, 2006) and 2,950 metres southeast of DON-44, the latest high-grade intercept in the Don zone. The presence of several higher grade zinc-lead bands within the active member in DON-45 combined with similar higher grade intercepts identified in the Don and HC West zones provides further encouragement for development of deeper mineral potential suitable for underground mining in Don valley (see news reported in Stockwatch on Oct. 25, 2006).

The deeper intercept in DON-45 is interpreted as a fault repeat of the active member whose distribution is unknown.
The Selwyn project exploration program is being reviewed by vice-president exploration, Jason Dunning, MSc, PGeo. The onsite activities for the Selwyn project are directed by exploration manager, John J. O'Donnell, PGeo. Both Mr. Dunning and Mr. O'Donnell are qualified persons within the meaning of National Instrument 43-101. All assay data have 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).
