VANCOUVER--(BUSINESS WIRE)-- Portrush Petroleum Corporation (TSX-V:PSH, OTCBB:PRRPF) (http://www.portrushpetroleum.com)

Portrush has commissioned a Calgary based Petrophysical Consulting firm to conduct a detailed evaluation on the Moore 6-12-III #2 well on its Waubuno property in Moore (St. Clair) Township, Lambton County, Southwestern Ontario. The evaluation is based on log evaluation and an oil show observed during drilling at the top of the main potentially productive porosity interval. The results will be considered preliminary until such time as the well is placed on production. The Company holds a 65% WI in the project.

The Raw Oil in place has been estimated at 806,000 barrels.

The report continues:

The "data presented herein indicates there is considerable Oil in place under the Waubuno (150-acres) pooled interest. The Portrush et al #2,Moore 6-12-111 completion candidate presents log data that compares favourably with log data obtained from nearby A1 Carbonate Oil Producers. The well if completed as an oil well would be expected to drain approximately 40 acres. This would indicate that at least three oil wells would be required to effectively drain the reservoir as postulated to cover 111.0 acres more or less (primary production)."
