Goldbrook’s Raglan Winter Geophysics Program Underway

Posted by on Monday, 17 May, 2010

Goldbrook Ventures Inc.,   announces the commencement of a winter geophysics program at its McCart Lake camp in the western portion of the Raglan belt, Ungava, Quebec in order to carry out a planned winter geophysical program.  Contractors, equipment and support personnel arrived at the McCart Lake camp site in early April, using ski-equipped aircraft, to carry out a program starting April 18th, of ground magnetic and EM surveying in preparation for an aggressive exploration and drilling program during the summer season.

About 1600 line-kilometres of continuous recording high resolution magnetometer surveys over various areas of interest are being completed by Clearview Geophysics Inc. These high resolution magnetometer surveys are conducted in “walking mode” in conjunction with GPS guided snowmobile towed mode. The magnetometer data provide the mapping information for the detection and delineation of ultramafic bodies which host Raglan-style mineralization.

Two crews, from Crone Geophysics and Exploration Ltd, are conducting up to 70 line-kilometres of moving loop electromagnetic surveys using a combination of SQUID and fluxgate sensors. These sensors are state-of-the-art instruments specifically designed to detect and discriminate the highly conductive nickel sulphides of the Raglan deposits.  The moving loop model of surveying is labour intensive, but provides the highest resolution.

The 2010 exploration program, with a budget of over $17,500,000, includes a goal of 25,000 metres of diamond drilling in conjunction with an extensive program of prospecting, geochemical surveys, geological mapping and ground geophysics over both the east and west extensions of the productive north and south Raglan horizons. This is an aggressive expansion from the previous, and successful, exploration focus on the Belanger Trend into new, and high potential geological target areas. This program will follow-up on the positive results of geological, geophysical and remote sensing surveys completed in these areas over the last two years and which helped with discoveries of extensive nickel sulphides at the Mystery and Timtu zones.  The work is expected to be successful in defining new sulphide nickel occurrences within the Company’s extensive Raglan Nickel Belt property holdings.

The large Goldbrook property is located in Nunavik, northern Quebec, Canada.

The 2008 exploration program consisted of 12,000 metres of BQ size core drilling, a remote sensing program that covered large parts of the Goldbrook property, a regional geology and sampling program, interpretation of VTEM geophysical data collected in 2007, and reclamation of two camp sites previously used for exploration in parts of the Goldbrook property.

There are numerous other areas of interest / showings that warrant analysis and search for specific drill targets. Some of these areas are also candidates for further geophysical surveys or tests with methods such as gravity, walking magnetics, ZTEM, and SQUID-sensor ground EM, and possibly for more detailed VTEM analysis. In addition, analysis of regional geochemical data (rock, soil and till) may provide insights or support other evidence for drilling.
