Our Technology
Innovation
GEM are focussed on bringing advanced technology to our customer’s projects in the most collaborative, planned and structured way possible.
Our technology has proven to be pivotel in enabling access to our client’s resources at an increased depth, both cost effectively and safely, allowing us to deliver on what we say we can do.
Jessy Deep Low Temp SQUID
(Superconducting Quantum Interference Detector)
We can provide many years of expertise in using the JESSY DEEP Low temperature SQUID for deep mineral exploration to our clients to benefit their programs.
Ultimate sensitivity and highest dynamic range are amongst the most prominent advantages over conventional sensors. It translates into higher depths of exploration, shorter duration of measuring campaigns and completely new types of information.
The superior performance of the receiver especially for late times even allows measurement of targets covered by a conducting overburden. Measuring the B Field direct results in sharper contrast for conductive ore bodies. Provides data up to 10 times longer resulting in an increase in depth of investigation by a factor of 3. High magnetic field resolution at low frequencies. Flat frequency response from dc up to 10 kHz.
Jessy Deep High Temp SQUID
(Superconducting QUantum Interference Detector)
We have been using these HTS SQUID systems for almost 10 years and our experience is therfore second to none.
The JESSY DEEP High Temperature SQUID for deep mineral exploration. GEM have been conducting numerous surveys with these German engineered SQUIDS and are very experienced in their use. They are fast becoming the prioritized choice for many client’s exploration surveys.
JESSY DEEP is the world’s most sensitive receiver for transient electromagnetic (TEM) measurements. The SQUID’s unrivalled sensitivity provides the exploration community with data of deeper targets or ore bodies covered with a conducting overburden then conventional receivers. The exceptionally high dynamic range of JESSY DEEP results in shorter data acquisition times and ultimately more efficient measuring campaigns.
SMARTem 24
SMARTem24 has been designed to be efficient in the field and to deliver the highest quality data. This compact, portable, 16-channel, PC-based package is the next generation of a system that has already set the benchmark in electrical geophysical surveys. The GPS synchronisation, small footprint, long-life batteries, a library of sensors to choose from and a bright colour touchscreen make this instrument a pleasure to operate. With the powerful signal processing software you have come to expect from a SMARTem receiver, full time-series recording and 24-bit ADCs make SMARTem24 data the best you will see anywhere.
High Power Transmitters
DRTX transmitters are capable of transmitting 100A through large transmitter loops. These high power transmitters are ideal for deep targets, or in areas with conductive overburden where depth penetration is limited with conventional lower power transmitters.
