Reminder – what is CMIC, and the
Footprints Project?

What is Canadian Mining Innovation Council?
www.cmic-ccim.org
Focusing on determining and providing the research
needed by the Canadian minerals industry to remain
competitive and sustainable, and to ensure excellence
in research, innovation, and commercialization
Network of mining companies, service providers,
universities, and government agencies
Canadian minerals research organization, created in 2007
SK Geol Survey Open House – 3 Dec 2013
Critical questions How to explore at depth in mature mining camps
How to explore under cover
How to define the entire ore system
How to apply new technologies and methods in the search
Requirement
Integrated matrix of geological, geochemical, mineralogical
petrophysical and geophysical features
(ORE-SYSTEM FOOTPRINT)
to enable identification of, and navigation within
ore-forming systems
CMIC: Exploration Innovation Initiative
See Robert and Galley, CMIC Signature Event Feb 2013

Ore Body
Erosion may disperse the footprint
Glacial cover will attenuate or obscure the footprint
Deformation and metamorphism may modify the footprint
Ore System Footprint
SK Geol Survey Open House – 3 Dec 2013
Ore Body
Develop multi-parameter models and data integration tools
Enhance signal-to-noise ratio (detectability) and vector from distal margins
to high-grade cores
Train and mentor geoscientists
Ore System Footprint

Copper Footprint:
Highland Valley porphyry Cu
Define the alteration,
geochemical, mineralogical and
petrophysical footprint
Identify the distal alteration
halo and its outermost
detectable limit
Characterise the geophysical
signatures through refined
analysis and modeling of
existing and new geophysical
surveys
Map source: Alva Jimenez (2011)
Copper Footprint:
The First Phase Mike D’Angelo MSc student
Research Associate has been hired and will
start in January, 2014
One MSc student is working on the
regional intrusions to determine the distal
footprint
Two PhDs will start next year working on
the architecture of the system and
alteration/mineral chemistry

Gold Footprint: Location
Malartic deposit
was relatively small
and high grade
Canadian Malartic
will be (is) very
large and high
tonnage
Should have a large
footprint, but not
yet obvious how it
will be expressed

-- Little outcrop, so limited geological mapping
– 30 years of exploration data, including 696 diamond drill holes
– Lithogeochemical data for 40,767 drill core samples, some with
only U and selected pathfinders, many with 55 elements from SRC
– Comprehensive airborne magnetic coverage, extensive airborne
and ground EM, airborne gravity, selective ground resistivity and
gravity
– EXTECH IV seismic survey (and associated work) and local
seismic surveys in the vicinity of some deposits
– Total gamma, SWIR, borehole sonic, resistivity for many holes

Millennium Volume: Focus of lithogeochemical and
alteration mineralogy analysis
SK Geol Survey Open House – 3 Dec 2013
MSc projects (just started):
Lithogeochemistry Geostatistical analysis of major and trace element
data (6026 points) from over 50 drillholes and
wedges, and 3D contouring of select element ratios
and alteration indices within GOCAD model
Shannon Guffey (Piercey/Kyser/Ansdell)
Alteration Mineralogy Mode, character, and crystal chemistry of illite and
chlorite from selected samples, and analysis of
mineral spectroscopy data within GOCAD model
Nick Joyce (Layton-Matthews/Kyser)
The projects will be integrated as
they are examining the same
drillholes from the same volume
Surficial studies: Geophysics and geochemistry
from Cameco Corp.
and in Kyser and Cuney (2009)
Overburden Stripping Remove affect on airborne and
ground geophysical signature
(less noise)
Significant for exploration across
Canada
SK Geol Survey Open House – 3 Dec 2013
Surface geochemical Which media and techniques
actually provide information
on “leakage” to surface – focus
sampling on “structures” in geological
model
