Terraquest’s King Air C90 Airborne Geophysical Survey Platform
Terraquest owns and operates a King Air C90, which is a powerful aircraft capable of high altitude flight, flight over mountainous terrain and flight in remote areas or offshore. It is an ideal, stable platform for carrying out a variety of surveys, including magnetics, horizontal gradient (up to 3 sensors), radiometrics, VLF-EM, LiDAR, and airborne gravity surveys.
Multi-function King Air C90 configured with two wingtip pods and tail pod for horizontal gradient surveys.
Shallow explorers can now benefit from the new Matrix™ Digital VLF-EM technology developed for Terraquest’s precious metals and diamond clients. Other surveys, as noted above, prospect to a range of depths. Over 216,000 line km of airborne gravity surveys have been completed on this platform since its inception in 1996.
The platform is equipped with accurate real-time corrected GPS navigation and data recovery for precise positioning on the ground. This is an essential capability as many explorers target and drill directly from airborne geophysical survey results and accurate positioning increases the potential of drilling success.
King Air C90 Logistics and Benefits
Terraquest has carefully selected the King Air C90 as an effective, stable platform for airborne geophysical surveys for high resolution airborne geophysical surveys using a variety of measurements. The platform is capable of relatively slow air speeds -- the ideal condition for acquiring high resolution, well-positioned data at a nominal ground clearance of 80 m.
Some of the advantages include a large payload for multi-sensor data acquisition, reliable and powerful twin PT6 21 turbine engines for climb and high altitude survey performance, and use of the ubiquitous Jet-A fuel which can be sourced worldwide for any project work.
The C90’s capabilities include operation in remote areas and capability for large productive surveys based on extended range and easy ferrying operations as well as long range fuel tanks for extended surveys over blocks during the survey day.
Safety
Terraquest’s King Air C90 operates under full Canadian Ministry of Transport approval and certification for specialty flying, including airborne geophysical surveys. The craft has low maintenance with 200 hour scheduled inspections. To ensure safety at all times, the system is maintained by a regulatory AMO facility, Enterprise Aviation of Oshawa, Ontario, Canada.

Piper Navajo Logistics and Benefits
Terraquest has added the Piper Navajo to its fleet based on a number of benefits for its clients in terms of acquiring Better Data, Better Results™. The Piper Navajo is suited for a number of airborne geophysical survey types as noted above and with its twin engines is equipped to survey over large bodies of water.
Some of the advantages include a large payload for multi-sensor data acquisition and with its extensive modifications it is a very magnetically quiet aircraft.
The Piper Navajo’s capabilities include operation in remote areas and capability for smaller targeted surveys as well as regional work. Flight endurance is five hours with extended fuel tanks.

Terraquest’s Cessna U206 Airborne Geophysical Survey Platform
Terraquest owns and operates two Cessna aircraft, one a U206, in addition to its other fixed wing platforms.
The U206 is a workhorse type of aircraft for performing all surveys from large scale regional airborne geophysical surveys to postage stamp size surveys. Drone operators also provide postage stamp surveys; however, the Cessna gives greater capability as well as multi-sensor airborne geophysical surveys – which are unmatched capabilities.
The U206 is a rugged, stable platform for carrying out a variety of airborne geophysical surveys, including magnetics, horizontal gradient (up to 3 sensors), VLF-EM and Lidar surveys (two camera ports). Recent surveys included a survey of 40 postage stamp sized blocks of 400 line km each, and a 15,000 line km survey over a large area, which were both completed ahead of schedule and under budget.
Workhorse Cessna U206 configured with two wingtip pods and tail pod for horizontal gradient surveys.
Shallow explorers can now benefit from the new Matrix™ Digital VLF-EM technology developed for Terraquest’s precious metals and diamond clients. Other surveys, as noted above, prospect to a range of depths.

Cessna U206 Logistics and Benefits
Terraquest has incorporated the Cessna U206 into its fleet based on a number of benefits for its clients in terms of acquiring Better Data, Better Results™. The Cessna is suited for a number of airborne geophysical survey types as noted above and is a lightweight aircraft capable of long flights.
Some of the advantages include a high wing which is ideal for unpaved and gravel runways and fixed landing gear which eliminates the requirement for time consuming gear swings. It is also a versatile aircraft for both extremely cold and hot conditions (piston engine).
In the bottom line, with Terraquest’s almost 40 years of airborne geophysical survey experience, notes that clients value the Cessna U206 platform simply for its excellent record of quality data acquisition.

Terraquest's Single Sensor Helicopter Geophysical Survey Platform
Terraquest utilizes helicopter airborne geophysical surveys with Resolution™ magnetics as well as with Max-Gamma™ radiometric, Matrix™ VLF-EM and EM-Power™ time domain electromagnetic survey capability.
For magnetics, a single magnetic sensor is mounted in a stinger which projects from the nose of the helicopter as shown below.
For EM-Power™ helicopter time domain electromagnetics surveys, a source / receiver coil is suspended on a cable from a helicopter and used to take shallow or deep electromagnetic measurements. Or for near surface investigation, the new Matrix™ Digital VLF-EM system can be used to produce resistivity maps, sections, and depth slices for each frequency.
Max-Gamma™ airborne radiometric surveys can also be operated with an advanced digital, automatic gain stabilization spectrometer with individual crystal processing; 4 crystals/pack, one pack (16.8 litres down).
