Outline

from Cameco Corp. 2012

Reminder – what is CMIC, and the

Footprints Project?

Activity and plans – Cu, Au, U



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

http://www.cmic-ccim.org/


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


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


Ground IP and gravity surveys (Abitibi Géophysique) Pit outline pXRF data

Samples

2013 : New data


2013 field work at Malartic

205 drill core and field samples collected along a NS section

Petrophysical data are almost already acquired (hyperspectral, density, electric properties, magnetic suceptibility and remanence)

Whole rock geochemistry and mineralogy analysis are in progress

1483 pulp samples

pXRF (90% already measured, Memorial Univ, S. Piercey, M. Crocker)

Magnetic susceptibility and gamma-ray measurements in progress

Over 2000 magnetic susceptibility data

Uranium Site and Public Domain






-- 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

– Lake sediment geochemistry, boulder sampling geochemistry

and mineral spectroscopy (limited other surficial data)

Dr. Mohamed Gouiza Expertise in structural and tectonic development of

sedimentary basins

Looking towards the E, with all Cameco holes

Sandstone/Basement Unconformity

Looking towards the E, with all Cameco holes

Sandstone/Basement Unconformity

Millennium Volume: Focus of lithogeochemical and

alteration mineralogy analysis


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


Surface geochemical Which media and techniques

actually provide information

on “leakage” to surface – focus

sampling on “structures” in geological

model
