Mining Projects
Overview
The
use
of
air
transport
in
mining
development
started
early
in
Canada.
Bush
planes,
like
the
Beaver
aircraft,
were
crucial
to
the
development
of
gold,
silver
and
nickel
mining
in
northern Quebec, Ontario and Manitoba.
Air
transport
enabled
people
and
equipment
to
undertake
resource
exploration
and
development
in
areas
that
are
virtually
inaccessible.
Roads
and
railway
lines
were
eventually
built
to
the
richest
of
these
deposits.
But
even
today,
Canada
has
the
renown
of
being
the
largest
single
market
for
helicopter services.
Despite
their
success,
bush
planes
and
helicopters
have
limitations
in
both
payload
and
flight
distance.
Development
of
large-scale
mines
or
energy
exploitation
was
only
possible
in
the
southern
fringes
of
the
north
where
rail
lines
or
road
links could be built economically.
Many
types
of
cargoes
are
required
for
mine
development
and
operations.
The
main
categories
include
construction
materials,
fuel,
equipment,
machinery,
cement,
explosives,
camp
supplies,
food,
etc.
Fuel
is
the
largest
single
input
requirement
that
limits
northern
development.
Supply
shortages
of
some
mining
provisions
may
be
a
nuisance,
but
a
fuel
shortage
can
be
a
catastrophe.
A
mine
that
is
forced
to
shutdown
its
concentrator
for
lack
of
fuel
may
never
be
re-
opened.
The
camp
would
face
some
very
significant
safety
issues without heat and electricity.
Transporting
fuel
is
costly
and
environmentally
risky.
Typically
fuel
is
transported
in
bulk
using
rail,
truck
or
barges.
Mines
that
have
no
railway,
gravel
roads
or
marine
access
must operate using ice roads during a short winter season.
Known
mineral
deposits
and
operating
mines
near
Yellowknife,
NWT
is
identified
on
Map
1.
A
seasonal
ice
road
serves
two
operating
mines
and
a
third
mine
under
re-
development.
Two
of
the
properties
are
diamond
mines
(Ekati
and Diavik) and the third is a gold property (Lupin).
These
mines
require
approximately
200
million
litres
of
fuel,
annually.
The
years
supply
of
fuel
is
trucked
over
an
ice
road
that
operates
for
a
12-16
week
period.
In
addition
to
the
fuel,
a
whole
years
supply
of
grinding
balls,
explosives,
plant
supplies,
non-perishable
camp
supplies,
etc.
must
be
moved
over
the
400-kilometer
ice
road.
The
transportation
cost
for
fuel
is
about
$40
million.
The
total
cost
for
all
freight,
including
building
and
maintaining
the
ice
road,
would
be
much higher.
The
capacity
of
the
ice
roads
out
of
Yellowknife
could
easily
be
reached
if
the
season
shortens,
one
of
the
mines
expands
(which
is
a
realistic
possibility
for
Lupin),
or
another
property
tries
to
connect
to
the
existing
road.
Adding
more
lanes
over
the
lakes
could
extend
capacity,
but
ultimately,
safety
concerns would impose an upper limit on traffic.
Transportation Challenges
Affecting Mining in the Territories
Diamond
and
gold
mines
require
large
volumes
of
fuel
and
other
supplies
to
be
trucked
in
to
their
operations,
but
the
monthly
output
can
be
carried
out
by
air.
This
is
not
the
case
for
base
metal
mines
(copper,
zinc,
nickel,
etc.)
that
have
much
larger
volumes
of
outbound
materials
to
transport.
This
means
that
for
economic
operations,
they
have
better
transportation
service.
An
example
is
the
undeveloped
Izok
Lake
discovery
that
is
located
in
central
Nunavut.
This
mineral
deposit
is
of
world-class
proportions.
The
grade
of
zinc,
lead,
copper
and
gold
(16.5
million
tones)
would
have
been
mined
long
ago,
if
it
were
accessible.
This
property
is
owned
by
a
large
publicly
traded
international
mining
company
(Inmet
Mining)
would
produce
350,000
to
400,000
tons
of
concentrate
annually
and
employ
250
persons.
A
pre-
feasibility
study
suggests
that
the
mine
would
have
a
minimum life of 13 years based on known reserves.
Several
major
mining
companies
have
considered
developing
the
Izok
Lake
reserve
but
all
have
failed
to
overcome
the
transportation
challenges
associated
with
economically
moving
mining
supplies,
principally
fuel,
into
the
mine site and concentrates back out.
Unlike
a
diamond
or
gold
mine
where
the
finished
product
can
be
brought
out
in
a
small
airplane
on
a
weekly
basis,
base-metal
mines
have
to
stockpile
their
inventories
for
9
to
10
months.
In
addition
to
the
direct
costs
of
ice
roads,
the
indirect
costs
of
financing
inventories
contribute
to
the
total
logistics
costs
of
the
mines.
Inmet
provided
the
following
comparative costs.
Mining
companies
have
examined
many
creative
solutions
to
the
Izok
Lake
transportation
dilemma.
Considerable
study
was
made
of
building
a
deep-water
port
on
the
north
shore
of
the
continent
at
Bathurst
Inlet.
This
port
would
be
the
terminus
for
a
265-kilometer
all-weather
road
to
the
mine.
The
cost
of
constructing
a
deep-water
port
and
building
the
road is estimated to be $250 million.
In
addition
to
transporting
the
concentrates
to
a
point
where
they
can
be
shipped
to
a
smelter,
there
is
a
requirement
to
haul
fuel
and
supplies
into
the
mine.
Also,
for
an
air
only
option
to
be
feasible,
the
aircraft
must
also
be
able
to
transport
the
equipment
and
construction
materials
to
site
as
part
of
the
facilities
construction.
An
Inmet
representative
has
estimated
that
to
be
competitive
with
ground
transportation,
excluding
the
cost
and
maintenance
of
the road, the airship would have to offer a price of $50/ton.
Isok
Lake
is
only
one
example
of
where
transportation
has
prevented
a
mine
from
being
developed.
The
lack
of
access
from
mining
sites
to
conventional
transportation,
such
as
a
port,
is
widespread.
In
an
attempt
to
resolve
this
issue,
the
Federal
Government
and
the
mining
companies
with
interests
in
the
area
sponsored
a
$6
million
study
to
consider
developing
an
all-weather
road
that
would
connect
with
the
existing
ice
roads.
In
addition
to
the
commercial
aspects
of
this
project,
there
are
important
social
issues.
Who
will
pay
for
the
road?
Do
the
economic
benefits
offset
environmental
impacts?
How
will
a
road
affect
the
aboriginals
living
in
the
area?
