“Working with GEM is always a pleasure. Data quality and production rates are outstanding. Field crews work autonomously and proactively, with a great work ethic. GEM never fail to provide professional and reliable surveys with the latest high quality sensors. We look forward to continuing to work with GEM for all our ground EM needs.” Louise L’Oste-Brown Geophysicist at Minotaur Exploration.

“I’ve been using GEM geophysics since they began in 2003 on many projects within Australia and overseas (e.g. Fiji, Vietnam, Tanzania). GEM are a well run, very reliable and responsible group and their hard-working crews consistently deliver high quality EM data with good productivity. They are able to efficiently mobilise though borders to remote sites, respect local people, and use local assistance where needed”. Paul Mutton Consulting Geophysicist at Touchstone Geophysics.

“I have no hesitation in recommending GEM Geophysics for all forms of ground and down-hole electromagnetic surveys. GEM Geophysics consistently achieve high standards in the field followed by delivery of quality data in a timely fashion. Every effort is made to accommodate client’s requirements where practical. Spinifex has always been able to rely on their operators to follow the proposed programme, but also show initiative in suggesting improvements to survey design and/or parameters as dictated by ground conditions. Their organisation, field practices and safety standards are excellent. They have always made every effort to conform to company policies specific to each site. Communication from the field crews is typically excellent resulting in clients trusting GEM with a high degree of autonomy in remote locations. GEM Geophysics is continually looking to offer the latest technology available to the exploration industry, thereby maximising the client’s chance of success.” Brett Adams Consulting Geophysicist at Spinifex Geophysics.

“I have used GEM for surface and down-hole EM surveys on numerous projects around Australia over the past 10 years. The data quality and production rates have always been excellent, and GEM’s crews are consistently experienced and professional. The Jessy Deeps SQUID sensor coupled with GEM’s 100A transmitter provides an excellent combination of sensitivity and power, and at a very competitive rate. I have no hesitation in recommending GEM to explorers looking for a reliable TEM survey company”. Kelvin Blundell
