BENTON RESOURCES, ROYAL ROADS & GOLDEN DORY APPROVE 2009 PROGRAM FOR LONG RANGE NICKEL JOINT VENTURE, NEWFOUNDLAND – DRILL TARGETS IDENTIFIED
"... Among the targets selected for further work is a 600 metre long VTEM conductive anomaly described by Geotech Ltd. as “a relatively strong conductor consistent with massive sulphides”. This target has been selected for testing by diamond drilling, and it is anticipated that additional targets will be developed from results of the prospecting and ground geophysical surveys."

Data Processing
Geotech Airborne Pty Ltd. provides expert data processing at field locations and at the head-office. At the field level, quality control procedures are designed to ensure that all data collected meets or exceeds contract specifications. Data compilation is done progressively during each survey, with preliminary maps being produced immediately after the flying is complete. Final data processing is done at the Geotech office in Aurora. Geotech uses the latest data processing tools and techniques to provide a wide range of final geophysical survey products such as maps, resistivity-depth sections and data profiles.
Below are some examples of the maps. Full-size sample maps in PDF format can be downloaded by clicking on the images below.
