Inc.,

On
Monday,
July
22,
Mr.
Borst
called
Mr.
Sippel
in
Canada
regarding
minimum
copper
content
required
in
secondary
materials
received
at
Noranda's
Horne
copper
smelter.
Mr.
Borst
placed
this
call
in
conjunction
with
evaluation
of
a
petition
by
World
Resources
Corporation
before
EPA
to
exclude
electroplating
sludge
from
the
definition
of
solid
waste
under
the
Resource
Conservation
and
Recovery
Act.
Mr.
Borst
reminded
Mr.
Sippel
of
a
prior
conversation
in
which
Mr.
Sippel
had
indicated
that
secondary
copper­
bearing
materials
received
at
Horne
had
to
have
a
minimum
of
five
to
ten
percent
copper
content
(or
equivalent
precious
metal
value)
on
a
dry
weight
basis
to
be
received.
Mr.
Sippel
confirmed
that
this
was
the
correct
range
but
wanted
to
confirm
this
with
his
plant
manager
at
Horne.

On
Wednesday,
July
24,
Mr.
Sippel
contacted
Mr.
Borst
in
Virginia
and
clarified
that
in
order
to
be
acceptable
to
Noranda,
a
secondary
material
would
have
to
have
either
a
five
percent
minimum
copper
content
on
a
dry
weight
basis,
equivalent
precious
metal
value
or
other
processing
value
such
as
significant
flux
content.
Mr.
Borst
questioned
Mr.
Sippel
on
the
presence
of
silica
in
electroplating
sludge
and
whether
or
not
lime
would
be
an
appropriate
fluxing
agent
at
Horne.
Mr.
Sippel
replied
that
silica
was
the
typical
fluxing
material
and
that
Noranda
would
not
purchase
lime
(calcium
hydroxide)
as
a
flux.

Mr.
Borst
and
Mr.
Sippel
concluded
the
conversation
by
discussing
the
value
of
services
provided
to
Noranda
by
World
Resources
Corporation.
Mr.
Sippel
indicated
that
WRC
created
an
infrastructure
for
electroplating
sludge
recycling
that
would
be
difficult
to
replicate
if
electroplaters
sent
their
sludge
directly
to
Noranda.

Date
of
Record,

Contact:
Andy
Mollison,
Manager
of
the
Custom
Feed
Department,
Falconbridge,
Sudbury,
Ontario,
(705)
699­
3915.

Mr.
Mollison
returned
Mr.
Borst's
call
to
Mike
Humphries
of
Falconbridge,
a
Canadian
nickel
smelter.
Mr.
Mollison,
Falconbridge's
Manager
of
Custom
Feeds,
indicated
to
Mr.
Borst
that
Falconbridge
operated
in
Ontario
under
a
certificate
of
approval
issued
by
the
Province
that
requires
processing
of
significant
metal
values.
Mr.
Mollison
said
that
in
order
for
Falconbridge
to
receive
a
secondary
material,
it
had
to
have
a
minimum
of
two
to
three
percent
nickel
content
on
a
dry
weight
basis.
Mr.
Mollison
offered
that
this
amount
would
cover
the
smelter's
processing
costs,
but
that
generator
would
have
to
offer
substantially
higher
levels
of
nickel,
five
to
10
percent,
before
the
generator
could
expect
to
paid
any
cash.
