ecennial Mineral Exploration Conferences (DMEC) has assumed the role of
‘patron’ of Exploration Trends & Developments in the lead-up to Exploration
’17, to be held in Toronto, Oct. 21-25, 2017. DMEC support came from the
companies listed in the Sponsor’s Box below.
The ETD review originated with the Geological Survey of Canada (GSC), where
for more than 50 years GSC scientists have prepared an unbiased annual publication
on trends and new developments in geophysical exploration for minerals. This
marks the 25th year that Patrick Killeen, has written the review, originally as a GSC
research scientist.
The Canadian Exploration Geophysical Society (KEGS) was the patron of ETD
between 2007 and 2016. DMEC and KEGS are committed to the promotion of
geophysics, especially as it is applied to the exploration for minerals other than oil; to
fostering the scientific interests of geophysicists; and to promoting high professional
standings, fellowship and co-operation among persons interested in these problems.

EXPLORATION TECHNOLOGY IN 2016:
AND THE BEAT GOES ON.....
A
s in 2015, the relatively low level of mineral
exploration activity in 2016 led more companies
to form partnerships, strategic alliances and
exclusive agreements, and to open new offices internationally in search of new business. However, there were signs of optimism
as well. At least two companies moved to new headquarters, a
new company offering advanced gravity exploration services
was formed, and at least one airborne geophysical survey contractor expanded its fleet. In terms of airborne survey activity,
most considered 2016 to be a “slow” year with activity picking
up towards the end of the year. To supplement decreased business from mineral exploration surveys, companies continued
to pick up an increasing number of surveys for groundwater,
environmental, geotechnical and even agricultural applications.
Advances and improvements in geophysical exploration
technology continued as system capabilities were enhanced
with increased sensitivity and new data processing techniques.
More companies modified helicopter-borne TDEM systems to
fly surveys faster. New AEM systems were tested and readied
for commercial surveys. A new generation Airborne Gravity
Gradiometer (AGG) system was successfully test flown and another company had a new AGG system in development. More
companies were processing AEM data for IP information and even
including it in joint inversions. Geophysical equipment was
made lighter and smaller for use on UAV (drone) platforms,
both fixed wing (FW) and quadcopters. A new compact, light-
4
weight, dual-mag compensator was developed for magnetic
gradiometers on a UAV. Several companies tested UAVs for
various geophysical surveys. A UAV flying a gamma-ray spectrometer for environmental surveys was demonstrated and
a new airborne gravity system was flown in an “optionallypiloted” aircraft. A full-tensor mag SQUID gradiometer, first
flown on a helicopter platform, was tested on a FW aircraft. A
new airborne VLF system was released along with a ground
version. AEM systems saw improvements and optimization
with increased power, frequency range, signal-to-noise (S/N)
ratio and target resolution, and one company claimed its upgraded system now has the highest RMS dipole moment of
any AEM system. A new multiparameter airborne system in
development combines Grav/Mag/EM/Rad sensors on one
platform. Other similarly integrated systems that include gravimeters became available in both helicopter and FW.
In ground geophysics, a new induced polarization/resistivity (IP/R) meter that can analyze up to 16,000 data points
on a decay curve was introduced and field testers for IP/R
measurements on drill core were enhanced to measure on
outcrops. One company introduced a new mini-contact probe
to its Near Infrared (NIR) field spectrometer to allow mineral
identification in a 3-mm spot area on a sample. A Magnetization Meter that can measure and differentiate between induced and remnant magnetization was released. In the area
of ground data acquisition and processing, major software
improvements, especially for 3D applications, were made. New

web-based 3-D EM modelling tools became available as well
as new joint inversion modelling of MT, IP and DC Resistivity data. In drillhole geophysics, an enhanced gravimeter
was introduced that can log holes much faster, reducing costs
significantly. In addition, new software was developed for
optical televiewer data that allows extraction of new information; two companies developed new precision or “intelligent”
logging winches; a new small portable borehole logger was
released; and a new, solid state gyroscopic logging tool for
accurate surveys of borehole trajectories was developed. New
data analytics were introduced to extract more geological,
geotechnical and rock mechanics information from borehole
logging data. Other advances included new downhole EM sensors with doubled sensitivity, an upgraded borehole gravity
system that can operate on a single conductor cable and a
BHEM system that can log “uphole” from underground.
Ground geophysics also saw improved ground EM systems
that can record three-component B-field and magnetic field
data and better QC and QA for both ground and borehole
TDEM systems, a lightweight third-generation UXO detection
system with seven real-time audio and visual target indicators; and a new gravimeter with Bluetooth integration and
handheld tablet-computer operation. In addition, new and
highly successful procedures for borehole IP and hole-to-hole
3D IP tomography were developed, as were new methods to
analyze seismic refraction data to extract geotechnical information. Other developments in ground geophysics included
the capacity expansion of IP/R surveys to more than 350
receivers; a new common voltage reference mode of surveying
that increases survey flexibility, efficiency and safety; better
post-processing software for IP/R systems; a new Broadband
MT system that records both AMT and MT data simultaneously; and a deeper penetrating GPR system suited to mineral
exploration that uses full waveform capture of reflection data
instead of high power.

works to continue to pull itself out of a five year long
slump. The main conference begins the next day with
two back-to-back plenary sessions; “State of the Art”
in the morning and “Integrating the Geosciences –
Lip Service or a Meaningful Way Forward?” in
the afternoon.
Exploration 17
Integrating the Geosciences; the Challenge of Discovery The ‘Must Attend’ geoscience meeting of 2017
In just over eight months’ time, the 6th Decennial
Conference will be held in Toronto. This conference
will mark the 50th anniversary of the Conferences
and is a testament to their long term relevance to
the Canadian and global exploration community.
Started in Canada’s centennial year, the purpose of
the Conferences has been to bring together industry
leaders to benchmark the important developments of
the past decade in the Conference’s key focus areas;
geophysics, geochemistry, remote sensing and data
processing and management. While the focus of the
Conference is on exploration technology, the target
audience is the practicing exploration geoscientist
who is increasingly required to understand and
manage what can appear to be a complex array of
technologies, leading to the Conference’s theme
“Integrating the Geosciences; the Challenge of
Discovery”.
The main conference program will run for three days
(Oct 23-25) in the Toronto Metro Convention Centre
but will be bracketed before and after by a number of
focused workshops and a geophysical field school to
be held prior to the conference in Sudbury, ON. The
‘warm-up’ session to the main technical program
will start Sunday afternoon (October 22) with an
open session entitled “Exploration Technology –
The Evolving Business Context” where a spectrum
of industry leaders will reflect on the current state
of play and where they see the industry going as it
The next day (October 24) will be a full-on series of
focused sessions covering the key technology areas;
Airborne Geophysics, Geochemistry Case Histories,
Ground & Borehole Geophysics, Analytic Methods,
Processing, Modelling, Inversion Spectral Geology &
Remote Sensing. As a special event, the Case Study
session will close off the day with the presentations
of the winning talks from the Frank Arnott Award
contest; an innovative crowd-sourcing contest five
years in the making that has drawn data sets and
contributing teams from all over the world.
On the final day (October 25), the focus of this
series of plenary sessions will be core themes of
the conference; Integrated Interpretation and the
major challenge the industry faces going forward,
Targeting-undercover and Targeting at the deposit/
mine scale.
On-going through the conference, delegates will have
access to the world’s major exploration technology
vendors with their latest in products and services.
With well over 1,000 delegates expected from around
the world coming next October to Toronto, Exploration
17 will be the ‘must-attend’ geoscience conference
for 2017.

RSI’s RS-607 gamma-ray
spectrometer mounted
on a UAV.
In 2016, Montreal-based Geosphair
Aviation concentrated activities exclusively on Airborne LiDAR surveys
in Quebec, flying more than 100 hours
with its two LiDAR-capable aircraft. In
September, Geosphair added a Piper
Navajo PA-31 to its fleet, equipped with
a Camera/LiDAR hatch, equipment rack
and long range tanks.
In April GF Instruments of Brno,
Czech Republic, moved into its new
headquarters, designed for the company’s
growing production of geophysical
instruments. The building and surrounding area combine facilities for R&D,
manufacturing, equipment storage and
training, with an outdoor site for testing
and calibration. The new facilities combine all activities on its own premises.
Concord, Ont.-based Pico Envirotec
Inc. (PEI) which supplies both airborne
and ground geophysical systems worldwide, delivered two turn-key airborne
geophysical survey systems that include
assistance with installation, certification
and commissioning. Clients in Vietnam
and India received magnetic, gammaray spectrometric and EM integrated
systems and operational training. The
company also assisted with P-THEM
operations in Japan. PEI has developed
an equipment upgrade program for
customers with older systems operating
in the field, offering a “trade-in terms upgrade” to supply brand new equipment
that meets today’s technology standards.
Radiation Solutions Inc. (RSI), based
in Mississauga, Ont., sold airborne gamma-ray spectrometer systems in Africa,
Asia, Australia and North America last
year. In the fourth quarter, RSI conducted
a demonstration flight for Canadian government officials of its newest airborne
product, the RS-607. The lightweight

RS-607 gamma-ray spectrometer is
designed to be mounted on UAVs, weighs
less than 3.6 kg, and consists of an array of small detectors. It was developed
in collaboration with scientists at the
Geological Survey of Canada for environmental applications and may have a
future in mining geophysics.
Sander Geophysics supplied its
AirGRAV technology to NASA’s IceBridge
project which is the largest airborne
survey ever flown over Earth’s polar
icecap.
Vancouver-based SJ Geophysics
continued to provide world-wide dataacquisition and consulting services for
a range of geophysical methods. The
company’s Volterra Acquisition System
caught the attention of other geophysical
service companies. Although it prefers
to operate its own instrumentation,
2016 saw the first lease of the system by
another geophysical contractor. R&D into
development of new methodologies for
MIP, MMR, and passive seismic will soon
lead to additional ground and borehole
acquisition services being offered by SJ
Geophysics.
In 2016, SkyTEM Surveys, headquartered in Aarhus, Denmark, opened
a regional office in Johannesburg,
South Africa. The company also partnered with Aurora Minerals Group,
an Australian-Kazakhstan company, to
provide SkyTEM technology in Kazakhstan and nearby. Aurora specializes in
the transfer of new technologies and
attraction of investments in the mining
and oil & gas industries.
Terraquest of Markham, Ont., has
provided high-resolution airborne
geophysical surveys for three decades
using gravimetric, total field magnetic,
horizontal gradient, radiometric and
proprietary XDS VLF-EM methods.
In 2016, the company won another
Ontario Ministry of Northern
Development and Mines (MNDM)
survey and also conducted surveys
throughout North, Central and South
America. Surveys are flown with
fixed-wing and helicopter platforms
with stinger or towed 3-sensor Triaxial
Gradiometer. Terraquest moved into a
new office location in Markham last
year.

GG Multi-Physics offers three EM technologies,
each with unique features for mapping variations in conductivity. In 2016, the company
deployed its Helitem system (with investigation
depth of more than 700 metres) on a largescale survey in Asia, and mineral exploration surveys in Africa, Australia, Canada and
Brazil. The Tempest EM system flew several
surveys in Australia and the company’s Resolve EM system was
used for exploration around the world to image from the surface
to 150 metres.
Discovery International Geophysics is using Gap Geophysics’
SAM (Sub-Audio Magnetics) technology in Canada primarily in
the helicopter-borne mode, which is a hybrid ground and airborne system. The transmitter is on the ground and the receiver,
which is a high-sensitivity, fast-sampling, total field magnetometer, is towed through the air by helicopter or mounted on a UAV.
The transmitter is either a long grounded dipole, or galvanic
source, with the connecting wire looped around the survey
area, or it can be an inductive transmitter loop. Results can
be interpreted in terms of magnetometric resistivity (MMR) and
magnetic IP (MIP) using the galvanic source, or as off-time TEM
data using an inductive source. The HeliSAM system has the
inherent deep exploration advantages of a powerful transmitter
on the ground, combined with the surveying speed and lower
cost per kilometre of an airborne system.
EON Geosciences of Montreal provides high-resolution
airborne magnetic, gamma-ray spectrometric, and gravity
surveys using fixed-wing aircraft or helicopters. Its helicopter-only techniques include both the ETHEM time-domain
and the Hummingbird frequency-domain EM systems. EON
completed a survey in the Otish Mountains region of northern Quebec for the Ministère de l’Énergie et des Ressources
Naturelles du Québec (MERN) and flew a survey covering
portions of northern Michigan and northeastern Wisconsin
for the United States Geological Survey (USGS). In late summer, Alaska’s Division of Geological & Geophysical Surveys
(DGGS) awarded EON an airborne magnetic survey in the
Porcupine River area of Alaska.
Geophysics GPR continued to offer airborne survey services
in heliborne and fixed-wing magnetic, VLF-EM, radiometric,
gravity and TDEM (GPRTEM). The GPRTEM system was significantly improved by reducing vibration noise and increasing
its electronic signal/noise ratio. The improved version is to be
tested at the Caber deposit in Quebec in 2017.
Moscow-based Geotechnologies continued its activities in
airborne time-domain and frequency-domain EM, magnetics and radiometrics. In 2016, it manufactured and installed
equipment for airborne magnetic surveys with an An-2 aircraft

for Alrosa. The company also provided technical support for a
frequency-domain airborne EM survey by the Norilsk branch
of VSEGEI. EM4H systems produced by Geotechnologies have
been used for Russian government survey projects since 2007
and it is now the most widely used airborne EM system in
Russia with about 100,000 line-km flown every year, including
2016. The company also started a large airborne survey project
in Rwanda using EM, magnetics and gamma-ray spectrometry
in August.
Goldak Airborne Surveys, based in Saskatoon, Sask., kept
crews busy to the end of the summer flying a regional magnetic
gradiometer survey for the Northwest Territories Geoscience
Office and a magnetic gradient/radiometric survey for Ontario’s
MNDM. In the fall, the company flew various projects for the
private sector in the Patterson Lake and South Athabasca region. Goldak is developing a new data-acquisition system with
an enhanced pilot interface for surveys in 2017.
Perth-based MagSpec Airborne Surveys is an Australianowned geophysical services company that collects and processes
high-quality airborne magnetic, radiometric and gravity data
from a variety of fixed-wing and helicopter platforms worldwide. After the standout 2015 Yalgoo survey conducted on behalf of the Geological Survey of Western Australia, comprising
over 110,000 line-km of detailed magnetics, radiometrics and
DEM data at 100-metre line spacing, the company reported 2016
started off as a dire year for contractors in Australia. Activity
started to pick up later in the year.
Groningen, Netherlands-based Medusa Sensing reported
a growing interest from the agricultural and environmental
markets, in its geophysical survey systems. In 2016, it delivered gamma-ray survey systems to clients in Canada, Brazil,
China and Europe. A collaboration with GeoDuster, integrating its lightweight, compact, airborne system with Medusa
spectrometers to be flown on a drone, continued. Medusa’s
first fully operational drone gamma-ray detector system will
be flying in early 2017. Tests are also anticipated for exploration applications (with Geodrones, a Paris-based startup) and
for crop field mapping (University of Wageningen). The drone
development is supported by the European Union EFRO fund.
Precision GeoSurveys, based in Vancouver, specializes in
flying low-level airborne geophysical surveys in remote and
mountainous terrain worldwide. In 2016, the company flew
1TEM time-domain EM, frequency-domain EM, magnetic, and
radiometric surveys across western Canada and U.S.

the company flew surveys for private companies in Australia,
Africa and Southeast Asia. It also continued the data acquisition and processing of the latest 2015-2017 New Zealand
Ministry of Business, Innovation & Employment airborne
geophysical survey, which includes more than 100,000 line-km
of heli-borne surveying and more than 70,000 line-km of
fixed-wing surveying. Thomson was also awarded a number
of large airborne mag/spec surveys for Geoscience Australia
in New South Wales and South Australia.
The company also continued to evaluate and test an entirely new airborne TDEM system, which is expected to be
offered as a commercial service in Australia from early 2017
and later world-wide. Development of the use of rotary wing
and fixed-wing UAVs to collect high-resolution magnetic data
is also ongoing.
Airborne Data Acquisition and Processing
In 2016, Lakewood, Colo.-based Condor Consulting worked on
exploration problems from early stage greenfields to detailed
assessments at mine sites. Work was split between projects
related to gold, base metals, (primarily copper) and uranium
(exclusively Athabasca Basin). The company reported its
GeoInterp lithostratigraphic assessment is now being applied
to all commodity types. Condor continued to develop a suite
of ZTEM case studies for porphyry copper deposits, adding
assessments for the Kemess deposit complex, in northern B.C.

the world. SGL flew several large airborne gravity surveys for
regional mapping and climate change studies in 2016, using
its AIRGrav technology. It also flew gravity and magnetic surveys in South America and Asia for petroleum exploration.
SGL flew several EM surveys with its frequency domain EM
system (SGFEM), including the second phase of a three-year
EM, magnetic, and radiometric survey in Ireland, and an EM
survey in Canada for mineral exploration.
In 2016, the Heli-GT helicopter 3-axis magnetic gradiometer
system developed by Toronto-based Scott Hogg & Associates
carried out surveys in eastern Canada for gold and diamond
exploration programs. The unique low noise combination of
four high-sensitivity cesium sensors and accurate pitch, roll
and yaw determination measures total field, as well as magnetic gradients in the east, north and vertical directions, fully
independent of towed bird orientation.
SkyTEM, whose SkyTEMFAST helicopter-borne TDEM systems
can acquire data at survey speeds up to 150 kph, has introduced
a lightweight composite frame with increased stability and rigidity that enhances helicopter performance and increases
flight safety. Now all SkyTEM systems are capable of flying fast
and can collect over 1,000 line-km of data in a single day.
SkyTEM was busy last year flying the SkyTEM312FAST
system with a dipole moment of 510,000 NIA, for mineral exploration and groundwater mapping. In Canada, the company
completed the acquisition of over 15,000 line-km of TDEM data
for gold mining projects in Nunavut and 10,000 line-km of EM
and magnetic data for gold exploration in Quebec’s Abitibi region. The company delivered post processing of airborne IP
signatures, along with EM and magnetic data. The survey was
completed in severe winter conditions in only three weeks in
January 2016 using SkyTEM312FAST. In the United States, the
system was employed primarily for water surveys in California’s
drought-stricken Central Valley and in Arizona, Nebraska and
Florida. In Africa, more than 15,000 line-km of TDEM data were
acquired in Angola and Botswana for diamond exploration and
a groundwater mapping survey was conducted in Botswana.
In Australia, Geoscience Australia used the 312FAST system
to fly a dual-purpose hydrological and geological survey: an
8,000 line-km regional mapping survey for both water and
minerals. SkyTEM also flew a graphite exploration survey in
Greenland, a geotechnical engineering survey for the Norwegian
Geotechnical Institute, a water exploration project in Sweden
and two surveys in Pribalkhash, Kazakhstan for minerals and
ground water, with partner Aurora Minerals Group.
Terraquest reported continued success with its proprietary
broadband XDS VLF-EM system and a frequency-specific digital
Matrix VLF-EM system from Magenta. The two systems complement each other, providing improved definition of conductors
with variable orientation. In 2016, Terraquest conducted test
flights in arctic conditions of its Poco Helicopter TDEM system,
designed to map to a depth of around 70 metres in conductive
terrain. Inversion software is now available for the Matrix VLF
system, showing the VLF in 3-D renderings. Recent flights over
the Athabasca Basin with the system showed strong correlation with known IP/R mapping.
Thomson Aviation, based in Griffith, New South Wales,

highest-grade undeveloped porphyry deposit in North America.
Resolution is somewhat unique as a porphyry because it has a
sulphide content level that produces a strong EM signature
with MT-style surveys, including ZTEM.
On a proprietary basis, Condor processed extensive ZTEM
and HeliTEM surveys over the Tier 1 Goldrush deposit (which
hosts more than 14 million oz. gold), in Nevada’s Carlin Trend.
Results from previously processed portions of both these
surveys, including gravity data on claims adjacent to Goldrush,
are available on Condor’s website as a summary case study. Condor continues to be a re-seller for the Pitney Bowes Business
Insight (PBBI) Encom line of geophysical software and for the
Model Vision software of Tensor Research, Sydney, Australia.

For the past 10 years, GeoDuster Technologies based in
Knysna, South Africa has been building a compact, unified
airborne Nav/DAS/Compensator/Controller (NDCC) system.
The commercially available GD_ICCS2b_ACC (125 x 70 x
175mm, 1.6 kg) is an energy efficient, integrated magnetic
compensator with real-time and post-flight options, data acquisition and touch screen navigation. The company offers
system integration and training services.
These systems have been installed on a variety of platforms, together with Medusa spectrometers, and magnetic
sensors and other high-resolution measurement and sensing devices provided by other companies. The compact size
of the system has attracted light aircraft operators implementing single pilot/operator scenarios. A new lighter, more
compact instrument for 2017 provides optional isolated
and monitored supply voltages to the sensors and systems
attached. The new system is targeted at the even more
SWAPC (Size Weight And Power Cost)-constrained applications in the UAV market but is flexible and scalable for
conventional airborne platforms. Ongoing R&D collaboration with Medusa Sensing has resulted in production of new
cylindrical spectrometer detectors in 1-litre and two-litre
‘stackable’ configurations.
In 2016, Aurora, Ont.-based Geotech began offering its
proprietary Airborne Induced Polarization (AIIP) AIIP mapping as well as AIIP removal, as commercial products for
all of its VTEM surveys, past and present. The company
also offers its proprietary superparamagnetic (SPM) discrimination algorithm for identifying and differentiating
SPM-contaminated EM decays from true Ni-Cu-PGE target
responses. The algorithm has already been applied to Geotech’s recent VTEM surveys in Greenland, Russia, China
and northern Canada. The ZTEM natural field EM bandwidth has also been expanded from its standard 30-720 Hz
frequency range to include frequencies as low as 22.5 Hz.
As promised last year, Medusa introduced its new sensorembedded gamma-ray data-acquisition and processing system developed in close collaboration with partner GeoDuster.

Aeromagnetic Surveying
Abitibi Geophysics of Val d’Or, Que., continued development
of AeroVision, its UAV magnetometer system. The company is
working with a new UAV designed to be more stable on takeoff
and landing. Flight performance tests took place in late 2016
to be followed by magnetic performance test flights.

The companies are working to reduce the size and weight of the
new system even further for UAV applications.
New-Sense Geophysics of Markham, Ont., has developed
the “dashboard,” a unique user-friendly, mobile and desktop
web-based platform that allows both crew and clients to monitor all aspects of a survey project with daily updates as survey
block flying progresses. The dashboard provides updates on
survey parameters and calibration results; progress maps
(flown, un-flown, and next-flight plans); access to preliminary
databases, grids and maps; data stream from remote base
stations (including magnetic, in-block weather station and
web cam feed) and images of the grids surveyed, up to and
including the previous day’s flights.
The GT-Grid mapping system originally developed by Scott
Hogg & Associates was designed to obtain the maximum benefit from measured magnetic gradient information and has been
used to process or re-process more than 1 million line-km of
gradient data collected by various airborne survey contractors
around the world. GT-Grid projects were carried out in 2016
for the Ontario Geological Survey as well as industry clients
in Canada, Australia, Kazakhstan, Paraguay and South Africa.
Maximum benefit is achieved with a full 3-axis system that
accurately resolves gradients in the north, east and vertical
directions. Total magnetic field distortion, caused by deviations
from an idealized drape surface, is accurately corrected by reference to the actual measured magnetic vertical gradient, not
the usual calculated vertical gradient, which is an approximation that does not account for magnetic trend direction.
TechnoImaging of Salt Lake City, Utah, made 3-D inversions
of entire airborne EM surveys a reality when it developed the
moving sensitivity domain approach to inversions. Now the
company is incorporating IP effects into the airborne inversion technique, allowing the recovery of IP parameters and
conductivity simultaneously in a fully coupled, non-linear
inversion. Negative transients in airborne data can be realistically fit while honouring the full physics of the EM problem.
This makes it worthwhile to reprocess old airborne EM data
to find a more robust conductivity model simultaneously with
IP information.
Petrophysical analysis is now being performed in-house
with equipment that can measure the complex resistivity
spectrum of core samples, find the IP parameters that account
for it and incorporate the information into the inversion. This
can be done for standard DC/IP surveys and for interpretation
of any EM survey data for a more accurate conductivity or IP
model. TechnoImaging has also developed methodologies for
interpretation of multiple geophysical data types. Multi-modal
geophysical data such as airborne EM and gravity gradiometry,
can be inverted jointly for multiple physical properties implementing Gramian constraints. The company is now offering
interpretation services based on these new technologies.
Markham, Ont.-based GEM Systems expanded its UAV
instrumentation by adding quadcopters and unmanned helicopters to the fixed-wing solution and developing a very light
Airbird that carries a high-sensitivity Potassium magnetometer, navigation gear, laser altimeter and a data-collection unit.
Using the navigation link, data are transmitted online to the
survey base station. Total weight of the Airbird is about 3.5
kg with a length of about 2.2 metres. A “Sling” magnetometer
with a suspended Potassium magnetometer sensor can also
be flown below a quadcopter.
Last year, Geotech introduced its Pacific Aerospace PAC
750XL, design-built for aeromagnetic technology, for extremely
low-noise fixed-wing magnetic gradiometry surveys in North
America.
In addition to its single magnetometer stinger, New-Sense
flies magnetic gradiometer stingers including a tri-axial boom
system that can be integrated with radiometric surveys. In
2016, the company carried out magnetic, radiometric and
gradiometric surveys in Mexico, Peru, Chile, Nicaragua, the
U.S. and Canada. It has developed an autonomous remote base
station that includes magnetic / diurnal monitoring, weather
station and camera feed. The remote station can be positioned
within a survey block providing real-time condition monitoring which allows flight crews to plan and execute safer flight
plans with current and accurate conditions. For any given
project, both live and historical data are accessible through
the company’s new “dashboard.”
RMS Instruments of Mississauga, Ont., introduced the
AARC51 in 2015, the newest compact (133 mm by 133 mm
by 216 mm) and light (less than 1.8 kg) member in its family
of Adaptive Aeromagnetic Real-Time Compensation systems,
designed for installation in UAV platforms. Field tests carried
out in 2016 produced positive results. For instance, compensation for an installation on a helicopter UAV (less than 25 kg

Exploration Trends & DevelopmentS
takeoff weight), with a Cs magnetometer sensor mounted on
a 1.5-metre boom, yielded improvement ratios slightly above
10, in line with typical performance in conventional aircraft.
Several built-in functions in the AARC51 critical to high-level
performance in UAV installations include flexibility for fieldcustomization of the transfer function implemented at the
front-end to tailor performance to the specific aircraft (e.g.
motor, rotor and on-board electronics), which allows realtime dynamic compensation of the effects of DC currents from
electronic systems and instrumentation.
In a new development, a prototype of a dual-magnetometerinput version of the AARC51, tentatively named AARC52,
was completed in the second half of 2016. While the AARC51
works with an external GPS receiver, the AARC52 includes
an embedded (dual-frequency, L-band corrections capable)
receiver. With the same form-factor as the AARC51 and only
slightly heavier (under 2 kg), the AARC52 is ideal for gradiometry work on UAV platforms. Production of the AARC52
is tentatively scheduled for mid-2017. Many features of the
enhanced performance of the AARC51 are available for retrofit into other models and also as an upgrade for older units.
System sales for conventional (fixed-wing and helicopter) platforms remained healthy in 2016, as did demand for its airborne
systems engineering and integration services and its training
programs throughout the world.
Geoscience BC awarded Sander Geophysics a large airborne magnetic gradient and radiometric survey in British
Columbia to map the mineral potential of west-central B.C.
with results to be publicly available in early 2017. The company
flew two large fixed-wing magnetic surveys for the Geological
Survey of Canada in northern Canada for regional mapping,
and one for Quebec’s MERN. SGL also started flying a helicopter
survey in Lao PDR, acquiring horizontal gradient magnetic data
and radiometric data.
Spectrem Air of Lanseria, South Africa, completed the commissioning of the Full Tensor Magnetic SQUID Gradiometer de-
veloped in partnership with the Leibniz Institute of Photonic
Technology (IPHT) in Germany. Most of the development has
been on a heli-borne platform and new tests are being conducted
on a fixed-wing aircraft. The partners plan to commercialize the
system and deploy the technology outside of South Africa.
Airborne Electromagnetic Surveying
In 2016, CGG Multi-Physics’ Tempest fixed-wing system underwent
extensive upgrades, with improvements and optimization for
mapping geology, groundwater and minerals. This next generation system is fitted to a Cessna C208B Grand Caravan, improving performance and reducing operating costs. A major
transmitter upgrade increased power by 30% with a faster and
cleaner Tx turnoff. CGG also completed receiver modifications
at both the high and low end of the frequency spectrum, significantly improving signal-to-noise. The system can now produce
data at selectable base frequencies from 12.5 to 15 Hz, increasing depth of exploration in areas of conductive cover and
ability to resolve conductivity differences in more resistive
areas. This new Tempest became operational in Australia in
December and will be available for projects in North America
in June 2017.
The design of CGG’s Helitem helicopter time-domain system
has switched focus from achieving the greatest dipole moment to achieving superior signal-to-noise ratio. HelitemC,
the latest variant, now has noise levels five times better than
the previous system. The addition of MultiPulse technology
extends the effective EM bandwidth for resolution without
compromising power, greatly expanding detection capability
for deep, shallow, and subtle targets.
GEM Systems has developed an airborne, two-channel,
digital VLF system with three sensor coils, measuring inphase and out-of-phase vertical field components up to 10
times per second. Two horizontal coils detect total horizontal
VLF field and its direction, and the search for optimum VLF

FDEM surveys.
station reception online is automatic. The same system is also
available for ground surveys, called “Walking VLF.” GEM is
now working on extension of the measurement of regular VLF
frequencies into a lower frequency range from 1 to 15 kHz for
use with a local transmitter.
Geotech introduced its new VTEM helicopter time-domain
EM system for hydrogeological and engineering applications
last year. The system features a lighter, redesigned transmitter
loop, new induction coil receiver sensor and advanced dataacquisition system. It can measure EM fields as early as 5
micro-seconds after the turn-off for more precise, near-surface
resistivity characterization in groundwater surveys. The new
VTEM gradiometer-receiver system features dual time-domain
EM measurements from two, vertically spaced EM sensors for
improved SPM (superparamagnetic) monitoring. Full Waveform
implementation for all its VTEM survey systems (VTEM, VTEMPLUS, VTEMMAX, VTEM ET) continued, providing accurate
time-domain EM measurements as early as 18 micro-seconds
after current transmission for improved near-surface resolution.
The aerodynamic and lightweight ZTEM Lite sensor is now
being used in towed-bird mode with a helicopter platform
for extremely high altitude (greater than 5,000 metres a.s.l.)
applications, specifically in the Andes of South America.
In 2016, Geotechnologies continued to improve its EQUATOR helicopter-borne EM system. The main features of EQUATOR are simultaneous time-domain and frequency-domain
measurements and a wide range of survey flight speeds. The
company added more high frequencies to the primary field
with no loss of time domain off-time data. There are now two
versions of EQUATOR. The EQUATOR-7 loop is 7.5 metres in
diameter, has a dipole moment of 50,000 Am2 and allows a
maximum speed up to 200 km/h. The EQUATOR-11 loop is 11
metres in diameter, has a dipole moment of 100,000 Am2 and
allows a maximum survey speed of 170 km/h, but has 20% better signal-to-noise ratio in the late time-domain channels.
New Resolution Geophysics (NRG), headquartered in Cape
Town, South Africa, specializes in ultra-high-resolution airborne
gravity, magnetic, radiometric and EM surveys. The company
released the latest additions to Xcite, a helicopter-borne timedomain EM (HTDEM) system, first introduced in 2015. Features
of the system include unique patented loop design (an inflatable bird), exceptional signal / noise and excellent depth of
investigation. In 2016, the system flew two sets of test flights
under typical survey conditions in Africa and Australia. The
first was over a Selebi Phikwe-type massive sulphide deposit
in Botswana, where the target was mapped to a depth of 360
metres. The second test flight was performed in Australia at
14
the Forrestania EM test range over two discrete and varying
bedrock conductors. The Xcite EM system detected a clear
anomaly over the IR2 conductor. The data acquired in the test
surveys confirms the system’s ability to accurately detect typical mineral exploration targets in Africa and Australia.
In 2016, Pico Envirotec enhanced another P-THEM system
to an output of 360,000 NIA. The unit is to undergo test flights
to be available for contract operations. The system has an adjustable dipole moment and can operate on base frequencies
of 25, 30, 75, and 90 Hz that can be changed depending on
survey requirements and location. The P-THEM system with
an estimated depth penetration of 300 to 400 metres is suitable for exploration for conductors and ground water, and for
environmental studies.
Spectrem Air claims that after completing a significant transmitter and loop upgrade, the SPECTREMPLUS airborne EM
(AEM) system now has the highest RMS dipole moment of any
AEM system. To take advantage of the increased power, the
company designed and implemented a new suspension system
in the towed EM receiver bird and a new, more sensitive receiver
coil is being developed. New processing techniques have been
developed to extract multiple windows from raw binary data.
Currently, up to 39 windows (client-specific) can be provided in
addition to the real-time on-board processed 11-channel data.
Spectrem Air has been experimenting with the integration of a
gravity (and in future, gravity gradiometer) system on its DC-3
aircraft to ultimately deploy a multi-sensor system that collects
gravity, EM, magnetic and radiometric data simultaneously.
Airborne Gravity Surveying
CGG Multi-Physics’ Falcon suite Airborne Gravity Gradiometer
(AGG) system was designed specifically for light aircraft and
engineered to isolate the instrument from aircraft noise to provide high-resolution airborne gravity data. CGG reported that in
2016, it flew Falcon and HeliFalcon surveys for clients in Africa,
the Middle East, Asia, Australia, and for the USGS. The company
flew airborne gravity and magnetic surveys in Southern Africa,
as well as a survey in Mexico for the Government’s Hydrocarbon Department. In late 2016, the Full Spectrum Falcon was
deployed commercially for the first time, in Indonesia.
By the end of 2016, three of CGG’s Falcon Plus systems —
launched in the spring of 2015 — were in operation globally.
Full Spectrum Falcon has increased resolution at very short
wavelengths due to enhanced processing for close line spacing. It also has reduced noise at long wavelengths because of
the data from an additional standalone strap-down gravimeter

(sGrav). This allows the acquisition of high-quality gravity
data to complement the measured Falcon gradients at long
wavelengths. At intermediate wavelengths, its performance is
comparable to the Falcon Plus.
In 2016, CGG partnered with Lockheed Martin to develop
the FTG Plus, a next-generation full-tensor gravity gradiometry
sensor. This instrument is 20 times more sensitive than current technology, reducing sensor noise to the point where it
is no longer a limitation on the use of gravity gradiometer
data. Accomplishing this to sufficient accuracy for exploration
required a series of upgrades and improvements to the configuration of the accelerometers that measure gravitational
acceleration.
Geotech’s GT-2A gravimeter.
Gedex Systems of Mississauga, Ont., has developed a new
generation airborne gravity gradiometer, the High Definition
Airborne Gravity Gradiometer or HD-AGG. In 2016, the company successfully demonstrated its two-axis system measuring
Gzz, Gxx, and Gyy with noise and resolution levels at the leading
edge of performance for fixed-wing systems. Gedex plans to
move the system to a larger aircraft to further improve performance and to begin commercial surveys this year.
Geotech is now offering helicopter and fixed-wing gravity in
North America using its GT-2A gravity systems, manufactured
by Canadian Micro Gravity (Toronto). Previously only available
through UTS Geophysics in Australia and Africa, the GT-2A
gravimeter can be flown onboard an Astar B3 helicopter, a
Cessna Grand Caravan or a PAC-750. Following successful test
surveys in early 2016 over the Vredefort Impact Crater in South
Africa, Geotech is now offering its new Integrated Helicopter
Gravity-ZTEM-Magnetic system for commercial surveys. The
new integrated system implements the ZTEM Lite aerodynamic
sensor and integrated cesium magnetometer as a towed-bird,
with the GT-2A positioned on-board an Astar B3 helicopter.
With its 12 AIRGrav systems operating worldwide, SGL flew
AirGrav surveys in North America, South America, Greenland,
Asia, Australia and Antarctica last year. For the majority of surveys, airborne magnetic data were recorded simultaneously
with the gravity data. A large airborne gravity survey in Greenland was part of the Oceans Melting Greenland (OMG) mission,
managed by NASA’s Jet Propulsion Laboratory (JPL). OMG, part
of NASA’s Suborbital Earth Ventures program, is intended to
pave the way for improved estimates of sea level rise during
the 21st Century by observing changes in ocean circulation
and glacier retreat over a five-year campaign using airborne
and ship-based assets. SGL’s role was to acquire and process
high-resolution gravity data using its AIRGrav system. The
data will be used by the OMG science team to infer sea floor
bathymetry to determine potential pathways for warm Atlantic
water to come into contact with the glaciers. SGL also flew a
large airborne gravity survey in Australia to support regional
geological mapping in the Kimberley Region of Western Australia. The survey was conducted on behalf of the Geological
Survey of Western Australia (GSWA), Department of Mines
and Petroleum, and Geoscience Australia. The fully processed data are expected to be publicly available in early 2017.
In 2016 SGL was involved for the seventh year in NASA’s
IceBridge project in Antarctica. The company supplied its AIRGrav airborne gravimeter to fly in NASA’s DC-8 and assist with
NASA’s polar research. The mission of Operation IceBridge is to
collect data on the changing polar land and sea ice and maintain
continuity of ICESat measurements until ICESat-2 is launched
in 2018.
The latest TAGS-7 airborne gravity system by Micro-g
LaCoste of Lafayette, Colo., has been flown on the Centaur
Optionally Piloted Aircraft with encouraging results. The Centaur robot flies with a safety pilot in U.S. airspace but is capable
of long-duration flights without a pilot. The Centaur line-following ability is a significant improvement over normal autopilot
performance and the company reports it is achieving consistent
repeatability in the 0.5 milliGal range.

Physical Rock Properties & Elemental Analysis
The SCIP Tester is an innovative instrument that measures
apparent resistivity and chargeability of drill cores and rock
samples. Quebec City-based Instrumentation GDD has enhanced
the SCIP Tester’s field mode to measure in-situ apparent resistivity and chargeability of outcrops and floats.
In 2016, Spectral Evolution of Lawrence, Mass., added a new
contact probe for use with its oreXpress field spectrometer for
mineral identification and analysis in exploration. The oreXpress
NIR spectrometer has very high resolution and sensitivity for a
field unit. Lightweight, rugged and battery-powered, it can quickly
collect accurate spectra. Using the optional EZ-ID mineral identification software, minerals can be identified by comparing target
spectra against library spectra. The new Miniprobe with a 3-mm
spot size was introduced for samples where minerals of interest
are in tiny areas.
Richmond Hill, Ont.-based Terraplus introduced the Pro
model for the KT-20 IP Induced Polarization/Resistivity Meter
to analyze decay curves with up to 16,000 data points for any
length of time on the curve from as early
as 2 ms. The KT-20 IP Pro calculates total
chargeability, initial chargeability, provides three Tau calculations and ability
to review the raw data. The KT-20 IP Pro
can also calculate chargeability using Mx
Fit and the traditional 20 windows method.
Mx Fit is an algorithm that uses a real-time
exponential decay model to analyze several
hundred data points on the decay curve,
increasing accuracy and confidence in measurements and the calculations. A new IP
reference pad can confirm the accuracy of
the various parameter results.
Terraplus also introduced the Qmeter

both remnant intensity with the Qmeter and induced magnetization with a magnetic susceptibility meter, a user can obtain the
Könisgsberger ratio, Q.
Ground Data Acquisition and Processing
In 2016, Toronto-based Geosoft improved its software technology with powerful performance upgrades, enhanced visualization and new support for displaying 3-D symbols, 3-D
drillholes, and geo-referenced sections. Updates to the Oasis
montaj extensions include the ability to invert IP and resistivity
data in VOXI and new IP QA/QC tools.
Oasis montaj and Target are now 64-bit applications that
enable users to work with much larger databases, voxels,
and grids. Two or more monitors can now be used to increase
screen workspace by dragging any window outside the Oasis
montaj or Target window to a second monitor. The company
updated 3-D graphics rendering for better transparency and
lighting in 3-D models, and added new options for visualizing
geology and geophysical data. New features for drillhole data
include the ability to create sections or level plan maps from
within the 3-D viewer, import multiple tables of drillhole data
from Excel or Access in a single step, and plan drillholes with
known deviation for more accurate targeting. ESRI LYR files imported with elevation values are now displayed in full 3-D.
For working with 3-D IP data, Geosoft introduced a new
utility to identify and remove readings associated with faulty
electrodes before further processing. The company also added a
new moving platform gravity workflow for processing shipborne
gravity survey data. With VOXI Earth Modelling, 3-D conductivity
and chargeability models can now be created from IP and resistivity data using a modern 3-D inversion platform. These models
can be integrated directly with geophysical or geological interpretations in Oasis montaj.
Kingston, Ont.-based Lamontagne Geophysics (LGL) completed a suite of utility HTML5 web applications for field and
model data plotting (3CPlotter), primary field vector viewing

(VectorPlot), and survey grid design (GridPlot) and continued
development of new web-based modelling tools. It also developed
a web app, MlpGL-MultiLoop X, for the EM modelling of multiple
thin-sheet conductors that can be in the form of curved surfaces
with variable conductance. Lamontagne plans to deploy a fullvolume 3-D EM modelling tool using the same MlpGL front end
(MlpGL-MGEM) on the LGL web site in 2017.
Toronto-based Quantec Geoscience improved its proprietary
software for joint inversion of datasets from MT, DC Resistivity
and IP surveys. The company now offers data processed with
“CLARUS V 1.0” for Joint Inversion Modelling. Based on the
“Wannamaker” Joint Inversion codes, the software allows full
display of data, response, and model generated by 2-D joint inversion of any combination of two or three of the data parameters.
This improved the modelling process and provides additional
products for deep TITAN24 and SPARTAN surveys. Joint acquisition and inversion of MT and DCIP is unique in the industry.
SJ Geophysics completed many surface Volterra IP and
EM projects in 2016, including projects that integrated both
survey methods. In Nevada, large-loop EM and DC resistivity
surveys defined conductive horizons potentially hosting lithium
brines. Large-scale Volterra-3D IP exploration projects were conducted in Myanmar, Colombia and Guyana, each requiring data
acquisition with customized survey designs. These ranged from
a high-density 3-D diamond array configuration with 80 active
dipoles and over 110,000 observations, to a large-scale regional
survey covering 23 sq. km.
Sydney-based Tensor Research continued to develop
the ModelVision magnetic and gravity interpretation system
since taking it over from Pitney Bowes. The drillhole modelling and inversion system has a new window-type designed to
emulate a drillhole log where the properties and position can
be edited within the hole, a map or a section. A new bodytype has been developed for modelling the position, dip and
dip azimuth of thin and thick magnetic sheets that have been
pierced by the drillhole. The magnetic and density properties can be resampled onto an existing drillhole dataset or a
planned 3-D drillhole and used as a predictive log during drilling operations. Constrained, 2.5-D voxel-style modelling and
inversion in cross-sections enables exploration of a range of
geological scenarios using a lithology painter concept to
assign magnetic or density property constraints for inversion.
Drillhole Methods
Abitibi Geophysics reported that the cost of Gravilog surveys
has been reduced due to enhancements made to the gravity probe by Scintrex. Down-hole travel velocity has been
increased and the new gravity sensor stabilizes more quickly.
Time required to log a 1,000-metre hole can be reduced by up
to 20%.
Luxembourg-based Advanced Logic Technology (ALT) reported its WellCAD software offers new ways to use the data
from its 2nd generation OBI-2G optical televiewer released in
2014. The user can now extract chromatic data from the image to be integrated with stratigraphic, geochemical, wire-line
or other geologic data. A new colour classification process in
WellCAD, allows determination of mineral phases from optical
televiewer images.
Crone Geophysics reported an almost equal usage of their three-component B-field probes
and dB/dt induction probes with its Pulse
EM TDEM systems. In addition to standard
ramp and off-time readings, Crone now

Kore Geosystems, a new company focused on data analytics
to derive geotechnical / rock mechanics information. In many
cases, DGI has been able to extract significant value from exploration drillholes and repurpose data to solve engineering
problems.
DGI has co-developed a 3,000-metre capacity winch with
GeoVista in the U.K. with a sensitive velocity control for highresolution measurements in deep drillholes. The winch was
used to acquire acoustic televiewer (ATV) data at depths exceeding 2,500 metres to measure the true orientation of breakouts,
faults and joints for geotechnical information. The company’s
improved horizontal logging system now produces higher-quality ATV data, to reliably measure orientation of breakouts in
shallow-dipping boreholes indicating the principal stress direction — important for ground control in underground mines.
Toronto-based Kore Geosystems (KORE) developed four
new data analytics and processing techniques for exploration
and mining applications. The first, the Quantitative Rock Type
Classification technique, identifies rock-type domains based on a
variety of data sources, such as mutli-element geochemistry and
downhole physical rock properties. The second, Predictive Analytics, predicts density estimates from mutli-element geochemistry or downhole rock property data. The third, Regional Stress
Analysis, is an inversion technique to calculate the regional stress
state from multiple boreholes (of any orientation) using ATV
breakout measurements. And the last, Mechanical Rock Property
Estimation from Drilling Parameters, infers mechanical rock
properties from drill-rig data (torque, rpm, rate of penetration,
etc.) to develop 3-D rock hardness models.
The new Gyro Path North Seeking Gyroscope (NSG) borehole
logging tool developed by Whitehorse-based Icefield Tools is an
advance in solid-state gyroscopic systems. The patented technology rapidly determines the trajectory of a borehole, with +/1 degree of accuracy after only one minute of measurement. The
rugged design of the NSG tool delivers consistent performance
in extreme drilling environments, in either memory or real-time
mode. Using the latest sensor technology, the instrument is
shock-resistant, easy to use and slim (30 mm diameter). Userselectable accuracy options are available, with measurement
times from 15 seconds to 15 minutes for very precise surveys.
A second prototype of a UTEM 5 down-hole sensor has been
built and is being tested by Lamontagne Geophysics. The aim
is to almost double the sensitivity over the first prototype to
achieve an improvement by a factor of more than five times
that of the BHUTEM4 sensor at 2 Hz base frequency and below.
The entire down-hole tool string has been redesigned to reduce
motion creep noise, a significant cause of errors in deep-hole,
low-frequency measurements.
Denver, Colo.-based Mount Sopris Instrument Co. has developed a new geophysical logging winch with a spool capacity
of 2,500 metres of standard 3/16” (4.76 mm) diameter, 4-conductor geophysical wireline. With this innovative 230VAC
50/60 Hz servo-controlled intelligent winch assembly, logging
and tripping speeds up to 60 metres/minute are possible, with
low-end user-controllable speeds of fractions of a metre/minute — used for any logging that requires precise winch control.
This relatively small-footprint winch (116 cm long, 94 cm wide,
and 81 cm high) with 630 kg maximum torque, is designed for
geophysical logging trucks or covered skids.

TDEM Receiver uphill.
Micro-g LaCoste’s Gravilog mining borehole gravity system
now operates on a single conductor cable with improved gravity
and depth accuracy. The Bluecap deep borehole gravity system has
also been completely redesigned for ruggedness and accuracy.
SJ Geophysics reported increased demand for its Volterra-BH
services, due to the system’s ability to survey below drill rods.
This allows drillholes with a high risk of collapsing to be surveyed safely and efficiently. In addition, the company completed an
underground Volterra-BHEM survey demonstrating its ability to
survey inclined (up-hole) drillholes. A 32-mm Volterra Borehole
probe was passed through BQ drill rods to the end of the hole,
with measurements taken as the rods were removed.
Ground Electromagnetic Methods
Abitibi Geophysics upgraded its InfiniTEM loop configuration
to InfiniTEM XL, increasing the depth of exploration. By using two transmitters, one on each lobe of the loop, it has a
dipole moment (power) four times larger than a conventional
InfiniTEM system. Used on a BHEM survey at SOQUEM’s B26
project in Quebec, the InfiniTEM XL clearly detected a conductor
more than 400 metres off-hole. The increased power has significant exploration benefits for both surface and borehole TDEM.
Abitibi continued its collaboration with Dr. James Macnae, geophysics professor at RMIT University in Melbourne to optimize
the ARMIT sensor for low-noise applications below 1 Hz. A prototype version of a borehole ARMIT sensor will be tested in 2017.
Abitibi acquired a multiplexer transmitter controller from
Perth-based EMIT to manage transmission to multiple TDEM
loops, reducing survey costs in geological environments where
numerous conductors must be resolved. The controller is used
for surface and borehole TDEM surveys with two or more transmitter loops. In response to increased demand for borehole Bfield surveys, Abitibi has acquired a second DigiAtlantis probe,
also from EMIT, which simultaneously records three-component
B-field data. In addition, it can be used to record the down-hole
magnetic field data. The B-field data are more sensitive to highly
conductive massive sulphides.

current monitoring and synchronization to other Phoenix instruments. The RXU-TMR continuously saves time-series records
of the TXU-30 output on a removable Compact Flash card or
transmits data with a wireless link to a companion receiver
system for real-time processing. The TXU-30 can also be driven by third-party instruments through its external drive input
for compatibility with any time- domain systems currently deployed in Canada and Australia.
Gravity Surveying
Concord, Ont.-based Scintrex and its sister company Micro-g
LaCoste introduced the next-generation CG-6 Autograv gravimeter. Among the new features are Bluetooth integration,
a light, compact redesign, and a handheld tablet computer
for remote operation, field reductions and Bouguer mapping
capability.
Induced Polarization
Abitibi Geophysics reported increased demand in 2016 for its
OreVision and IPower 3D induced polarization configurations,
as drilling confirmed their ability to detect and delineate mineralization targets deep under conductive overburden. Based on
success with this technique at the Detour Lake mine in Ontario,
Detour Gold has now begun systematic coverage of its claims,
where conventional IP was unable to penetrate the clay layer.
Also, Midland Exploration reported a new discovery in a wellexplored area using OreVision on its Heva gold project in Quebec. Abitibi’s borehole IP procedures include both borehole IP
logging and Hole-to-Hole 3D IP tomography. The proven record of discoveries with these IP procedures is a result of the
large volume of exploration between and around holes. A good
example is work at a Golden Tag Resources project in Mexico.
After drilling an off-hole target delineated by Hole-to-Hole 3-D IP
it was found that the IP chargeability high was right on the top of

With the CDR3 time-domain EM Receiver put into production in
2014, full-waveform time series borehole and surface EM data
acquisition became standard survey practice for Crone Geophysics in 2016. A new noise rejection algorithm that enables
the collection of quality EM data through certain types of noise
has been added to optional tools used during the collection and
QC of data.
Discovery International Geophysics offers the Jessy Deep,
high-temperature SQUID sensor for deep TEM exploration under
a North American exclusivity agreement with Supracon AG
from Jena, Germany. The high sensitivity of magnetic measurement possible with a SQUID sensor provides increased
signal-to-noise TEM surveying for deep exploration of highconductivity targets. Last year, Discovery carried out surveys
across Canada and the U.S. for base metal and uranium exploration; one resulted in the discovery of a nickel deposit in
northern Quebec.
In 2016, Mississauga, Ont.-based Geonics introduced a third
generation of its UXO detector, now called the EM61 BLU26
Array-MK3 for detection and discrimination of BLU26 sub munitions. The new modular system, with a 2-metre or 1-metre
detection swath, is lighter and has a primary mode of real-time
operation with seven different audio and visual target detection
indicators. It also includes a large memory for recording and
post-processing analysis.
Instrumentation GDD has integrated more tools and
options with the NordicEM24 Receiver and EM Post-Processing
software to improve data quality, including new filtering options
and better management of noisy data and decays. To detect excellent conductors, the EM Post-Processing software now allows
extraction of the On-Time decay and profile from the fullwave
data for analysis of in-phase EM responses.
After testing of medium-power prototypes, Lamontagne Geophysics has built a high-power prototype of the UTEM 5 transmitter with two times better current waveform fidelity and
power efficiency improvements of over 30%. Power dissipation
is also four times lower than in previous systems. Full-power
operation can now be achieved with a generator of less than 8
kW, compared to 11 kW previously. The new prototype, which
is roughly half the size of comparable UTEM 4 high-power systems, is being tested in field conditions to determine if its size
can be further reduced and its maximum output increased. The
objective is to use the same transmitter model at power levels
ranging from 2.5 kW to 10 kW.
The TXU-30 transmitter made by Toronto-based PhoenixGeophysics is a controlled current source that can be used for
time-domain methods (less than 100% duty cycle), or frequencydomain methods (100% duty cycle). The TXU-30 is designed to
use either a grounded (or resistive) load connected to the earth
by electrodes, or an inductive load using a wire loop. With a 30kW power output, the new upgraded TXU-30 now permits up
to 60 Amperes in an inductive loop for Time Domain EM operations. The TXU-30 is powered by a 208 V, three-phase generator.
The company recommends at least a 45-kW generator for output up to 60 Amperes in loops up to 2 by 2 km. Transmission is
synchronized with GPS satellite time signals for accurate stacking of waveforms without any physical link between the TXU-30
and a separate receiver.
The TXU-30 can be driven by a Phoenix RXU-TMR for timing,

the polymetallic Endoskarn Zone and the chargeability anomaly
corresponded exactly in size and shape to the zone.
Crone’s 3D E-SCAN technology, an arrayed IP / R data-acquisition, inversion and mapping system acquired in 2015, was
used in northern Ontario last year on its first commercial project. The system successfully surveyed a prospective area in true
3-D high resolution, using its unique omnidirectional pole-pole
array to optimize depth penetration. The deeper and unbiased
3-D inversion provided a better geological interpretation and
generated new targets, since proven by drilling.
Saskatoon, Sask.-based Dias Geophysical continued to develop
its proprietary DIAS32 resistivity and IP technology. The company expanded survey capacity to over 350 receivers/channels from 100. Dias also developed the revolutionary common
voltage reference mode of surveying with the DIAS32 system,
providing benefits in safety, survey flexibility and efficiency. Each
single-channel receiver is part of a wireless network that transmits data, quality control, and system health information to the
operational base.
Dias has carried out surveys in a variety of configurations,
including gradient, pole-dipole, dipole-pole-dipole (distributed
multipole), hybrid 3-D, and full 3-D. The single-channel system
architecture allows for any survey mode at any scale. Timeseries data were acquired on all surveys, with the current
waveform measured at two key locations for each survey. In
2016, the company completed commercial resistivity and IP
surveys in Chile, the U.S. and Canada, including a 3-D survey
over NexGen’s Arrow deposit along the Patterson corridor in the
Athabasca Basin. A DIAS32 3-D survey was also completed in a
groundwater application.
Multipole Resistivity Imaging or MRI-32, a deeper and higherresolution mode of IP/resistivity surveying developed by Discovery
International Geophysics, has seen renewed interest with the
use of the Dias Geophysical DIAS32 distributed array instrumentation. The technique combines pole-dipole, reverse dipolepole, and pole-pole array configurations in one pass along the
survey line. Current injections are performed at the mid-point
of the dipoles, as well as at each electrode, for greater resolution. The technique has inherently better resolution because the
combined forward and reverse arrays provide more control on
the inversion of the survey results. The pole-pole data provide
greater depth of exploration. The main drawback of the technique
has been its cost as more personnel are required to perform the
various surveys simultaneously. However, the DIAS32 system
avoids this problem through its distributed array technology and
also allows for greater “n” levels.
Instrumentation GDD’s new digital IP Transmitter (model
Tx4) allowing 10,000W-4800V-20A in a Master-Slave configuration will be enhanced in 2017 with the capability of connecting
four units in series to reach up to 20,000W-4800V-20A. Including
GPS synchronization and real-time current recording options
via the EM-IP Tx controller, the Tx4 will optimize IP/R survey
data and daily production.
GDD’s IP post-processing software can now display Pseudosections of raw and processed data. The GDD IP Post-Process
tool can be used to visualize the fullwave Vp, to manually discard
noisy half-cycles to improve data quality, to re-window the Vs
decay (chargeability) and to enhance apparent resistivity computation using real-time current (with the EM-IP Tx Controller). It

is compatible with Windows 7, 8 and 10. In 2017, users of GDD
IP Receivers will be able to merge and process files collected from
multiple receivers all together. This new IP Post-Process option is
ideal for large-scale regional surveys such as those carried out
for porphyry-copper exploration.
IRIS Instruments of Orleans, France, has improved the software for its FULLWAVER distributed resistivity and IP system
designed for 3-D deep surveys. The FullWave Viewer software
is used for all pre-processing steps. Since cables are not necessary between V-FullWaver modules, the setup is geometry free.
The software offers easy spike rejection and automatic batch data
processing. A data file is created by merging the clean signal and
the current GPS time-stamped raw samples. The output data file
is compatible with available inversion software. A manual option
to use filters in the pre-processing can improve the quality of
noisy signals.
Quantec Geoscience introduced new survey design tools for
survey planning that work with Google Earth. ORION3D and
SPARTAN IP deployments are infinitely flexible due to untethered autonomous DAS operation. Survey lines in rugged or environmentally or culturally sensitive areas can be configured to
minimize impact and cost. New alternative deployments of ORION3D and SPARTAN address true 3-D data-acquisition issues in
complex environments that prove difficult to interpret when collecting data in 2-D. SPARTAN now collects either MT or IP and
provides the vast amount of data required for the most precise
inversion results in configurations such as “Roll along,” “Swath”
and randomized. Now, the ORION3D setup also provides preliminary 2-D TITAN lines for immediate reference and targeting
prior to the completion of a survey block.
For safety, Quantec has designed and built lightning shunts
that protect crews from electric surges hidden from routine
storm monitoring that may be brought to the survey along the
infinite wire which may be up to 10 km long.

Exploration Trends & DevelopmentS
In early 2016, PhoenixGeophysics introduced its new Broadband MT (BMT) sensor for both shallow and deep exploration.
Shallow exploration (less than 1 km) uses the high-frequency
component of the natural EM spectrum originating from distant lightning. This was commonly referred to as Audio Magnetotellurics (AMT). MT also deduces the earth’s subsurface
conductivity from measurements of natural geomagnetic and
geoelectric field variations, but investigation depth ranges from
300 metres by recording higher frequencies, to 10,000 metres
or deeper, by recording long-period soundings. The new Phoenix
MTC-150 is a true broadband MT- AMT Induction Sensor that
permits the simultaneous collection of both AMT and MT data in
a single run for a Broadband MT sounding (BMT) without mode
switching, for collection of both signals without an operator. The
amount of high-frequency (AMT) data collected is much larger
than in the past, and as collection is typically performed overnight,
the system provides data from 10,000 Hz to DC with a minimized AMT deadband impact. Having broadband data allows
inversion techniques to be better constrained by near-surface
information and to deliver useful information for MT static shift
distribution. The BMT sensor has the same dimensions as a regular MT sensor, but is lighter (6 kg instead of 9 kg). It has now been
adopted by more than 25 companies worldwide.
SJ Geophysics conducted the first two commercial VolterraMT surveys in 2016 with its Volterra technology that uses sensitive B-field coils with a frequency range of 0.1 Hz to 10 kHz.
Fluxgate magnetometers are also available to acquire responses
at lower frequencies. Both the Electric field (Ex, Ey) and Magnetic
field (Bx, By, Bz) are acquired with the same data acquisition units.
The MT data can be collected in a variety of configurations, from
simple scaler MT soundings to complex 3D Full Tensor MT arrays with numerous electric dipoles and multiple B-field sites.
The latter configuration can be integrated with a 3D IP survey
using the same electric dipoles.
Unique to SJ Geophysics is the ability to take short-interval
MT readings during integrated Volterra 3D IP-MT surveys. With
these surveys, the MT response is measured via multiple shortinterval MT readings during quiet periods of the DC Resistivity/
IP acquisition. The multiple MT responses are processed separately, then stacked and averaged. Longer dedicated MT readings
before and after the IP acquisition are also taken.
Ground Penetrating Radar (GPR)
Toronto-based Groundradar specializes in the design and use
of deeper GPR technology for mineral exploration. The company
has over 100 of its UltraGPR instruments in use worldwide. UltraGPR has been improved to provide deeper penetration in a more
portable and wireless instrument. Radar penetration is a function of mean output power and frequency, not peak power. Increasing the transmitting power alone will not improve penetration. By using standard-power transmitters and full waveform
capture of reflection data, UltraGPR enables stacking 128,000
times at survey speeds of 30 km/hr, significantly increasing penetration depths in suitable environments. The latest UltraGPR
weighs 3 kg, includes a built-in RTK-DGPS positioning system
and is operated using an iPhone or Android phone. Groundradar
now provides training with instruments and acquisition at no cost,
charging only for data processing. This allows the technology to
be deployed for large projects at low cost.
GPR is an effective tool for use in underground mines and
quarries because of its ability to image the geologic structure
in electrically resistive materials like granite and evaporites
like salt and potash. Sensors & Software of Mississauga, Ont.,
recently collaborated with the Canadian potash industry to
develop BackTrak, a borer-mounted GPR system to assist with
potash operations. As the borer starts, a mechanical arm automatically moves the GPR sensor into contact with the back
(mine roof) a few metres behind the cutting face. Data collection
follows the borer’s forward movement. GPR signals penetrate
several metres into the back providing a real-time image of rock
structures. Of particular importance is the ability to detect thin
clay layers that can lead to partings in the back, resulting in rock
falls. BackTrak features an automatic layer-tracking algorithm
to follow strong reflections from the key marker bed. A continuous readout of the current back thickness to the marker bed is
provided to the operator with a warning when salt thickness to
the marker bed becomes too thin. The data display also highlights other features of interest to mine engineers such as faults,
partings/voids and solution zones.

Magnetotelluric (MT)
ClearView Geophysics of Brampton, Ont., enhanced its analysis
of seismic data acquired using a gun powder source. Standard
seismic refraction surveys and analysis are now combined with
MASW (Multichannel Analysis of Surface Waves). These enable
better estimates of the depths to various layers within overburden,
depth to bedrock, depth to water table and in some cases, changes
in bulk density of overburden and bedrock layers. Seismic refraction analysis relies on accurate picks of the time of first arrivals of
seismic waves to calculate the Vp (p-wave velocity) for the different layers. However, many types of rock and overburden have
the same Vp and cannot be differentiated. By optimizing the location of standard seismic shots, MASW can provide Vs (shear wave
velocity) information for higher resolution of depths to layers
with similar Vps but different Vss. Bulk density is not always
directly proportional to Vp or Vs, but in some cases qualified
estimates can be made. These enhanced interpretive results can
also be used to calculate standard geotechnical parameters such
as Poisson’s Ratio and Bulk Modulus.
