An airborne time-domain electromagnetic geophysical survey using Geotech Limited's deep penetrating helicopter-borne VTEM
system will be flown over the most prospective portions of West Raglan.
The drilling programme will be guided by historical exploration results for the area and the results of the VTEM
survey and will include the drilling of approximately twenty boreholes to an average depth of 200 metres.
modeling results indicate a consistent moderate westerly dip to the gossan-associated conductors, with average depths of 30 to 70 metres below natural surface.
Aeroquest says, "The VTEM
max or Versatile Time Domain Electro Magnetic system is the most innovative and successful airborne electromagnetic system to be introduced in more than 30 years.
The company recently undertook an airborne VTEM
survey of the property, consisting of 1,850 line kilometres.
Sydney, Australia, Nov 28, 2012 - (ABN Newswire) - Sheffield Resources (ASX:SFX) today announced the identification of four high order anomalies from the first pass VTEM
airborne electromagnetic (EM) survey undertaken at its Red Bull Project.
and magnetometer survey covering 1,700 line kilometres delineated numerous targets favourable for gold deposits associated with banded iron formations as well as targets that exhibit high potential for massive sulphide copper, zinc, gold and silver deposits.
Masse" anomaly which coincides with a new VTEM
anomaly (airborne EM).
This is an important addition to the Complex, as it is associated with a nearly continuous VTEM
airborne geophysical survey anomalous conductivity trend over the same distance.
In 2004, the MacDonald carried out an airborne VTEM
and magnetic survey consisting of 50 to 75 metre-line spacing, where 40 anomalies were defined on the Big Mac property and 25 on the MacNugget property.
geophysical anomalies are slated for drill-testing.
It is the first time that a VTEM
survey has been started in Sri Lanka.
