Airborne EM Extends I.P. Target; Several Large Coincident Mag Targets Identified
VANCOUVER, BC, July 19, 2006 - Grande Portage Resources Ltd. (TSX-V GPG) ("Grande Portage" or "the Company") is pleased to announce that a preliminary evaluation of the recently completed 1,474 line km airborne EM and Mag geophysics confirms the results of the earlier 3-D Induced polarization ground geophysics and extends the target length to in excess of 5 km.
The ground geophysics survey, which generally has a greater depth penetration and accuracy than airborne surveys, detected a chargeability anomaly that remained open to the southwest at the extent of the surveys at the time. The airborne EM detected the southwest extension and extended for an additional 4.2 km, with a parallel zone to the west continuing for 2.0 km. At least 2 east/west conductors crosscut this trend for an excess of 4km. Other coincident Mag and EM anomalies occur 5km southwest of the Merry Widow pits and the focus of the first 24 drillholes; along the western edge of the airborne survey; and to the north. The Company is extremely encouraged that the results to date continue to provide significant insights. The precise size of each anomaly will be discussed in detail once the Company has received the final results of all the data plots and filtering expected sometime in August.
With the Merry Widow open pits as the model for skarn related massive sulphide mineralization occurring proximal to the magnetite, an initial review of the airborne magnetics shows that the previous mining focused within a discrete Mag high. The airborne Mag reveals a cluster of similar Mag highs varying in size and dimension, many of which are larger than the original discovery.
This is significant as no previous exploration knowledge of these targets has been located to date. These are new areas which will require initial investigation to determine if they are magnetite bearing and if skarn related massive sulphide mineralization also occurs within these bodies. Regional geological mapping indicates that the geology is similar.
The Company is presently drilling the first diamond drill holes into the I.P. generated targets. Should the holes successfully intersect massive sulphide mineralization along this trend, further ground geophysics will commence along the entire EM detected anomalies to further refine future drillhole selection. These grids will extend southwest along the main trend, along the parallel western zone, and will be targeted on new areas.
The exploration program is being conducted under the direction of Warren Robb, P.Geo. and George Nicholson, P.Geo, both are qualified geologists as defined under National Instrument 43-101. Both individuals authored this news release.
