MINING FOR CLOSURE
13
As stated in Section 1.3, this document seeks to ad-
dress three distinct components of the interaction
between mining, the environment and society in
SEE/TRB. Similar to other mining related initiatives
(c.f. ANZMEC MCA, 2000 for instance) it address-
es the operation of existing and new mining opera-
tions. However, as distinct from such initiatives,
“Mining for Closure”
in this document is intended to
encompass the stimulation and the creation of new
and innovative frameworks to support the re-mining
or otherwise valorising of abandoned or orphaned
sites and the closure and making safe of such sites.
This document is intended to build on calls for
such frameworks (see for example, Post Mining Al-
liance, 2005), and existing governmental advances
in practice in some jurisdictions (see for example,
Gammon, 2002).
Clark
et al
. (2000) summarises the challenge of a
process he terms integrated mine closure as follows:
Comprehensive mine closure for abandoned mines,
presently operating mines, and future mines remains
a major challenge for virtually every mining nation
in the world. To accommodate the need to close
abandoned mines and to ensure that existing and
future mines are appropriately closed will require the
cooperation of a diverse stakeholder community, new
and innovative methods of financing closure and
major policy and legislative change in most nations
to ensure post-mining sustainable development.
Mining for closure
requires recognition that min-
ing is a temporary use of land, but that the nature
of
potential
impacts can be exceedingly long term.
Further, such impacts can negatively affect a wide
range of stakeholders and economic development
in addition to the ecological environment.
Mining
for Closure
is a sustainability issue – not just an en-
vironmental issue.
As Robertson, Shawand others (1998; 1998) note, the
interest of amining organization in the land generally
terminates with the implementation of a closure plan
– a closure plan that is generally focussed upon items
such as optimized resource extraction, achievement
of regulated environmental objectives and cessation
of ongoing liabilities
23
(Laurence, 2003) as quickly as
possible and at as low a cost as possible. As such, a
mining organization often has, and traditionally has
had, a short term planning perspective – a view that
is significantly misaligned with the temporal aspects
of potential impacts (Strongman, 2000; van Zyl
et
al
., 2002a). The same may even be true of regulatory
bodies (Smith & Underwood, 2000).
The objectives of present-day mining industries
with regard to mine closure are often similar to
those of the regulatory authorities. Owners and
operators wish to eliminate future liabilities as far
as possible to obtain a release from planning and
discharge licence conditions or bonds and to give
them the freedom to dispose of their sites at the ap-
propriate time (Smith & Underwood, 2000).
This contrasts markedly with the interests of the
succeeding custodian(s) and associated stakehold-
ers. These actors are (or should be) far more focused
upon the continued sustainable use of the land(Strongman, 2000). In current frameworks, such
custodial interest generally only commences when
a closure plan is completed (Robertson, 1998).
In the past, communities often saw that the only
choice available was whether a deposit should be
mined or not. However, it has been shown that the
manner in which a mine is planned can have major
influences on themagnitude and duration of impacts
over the life of the development and following its clo-
sure (Environmental Protection Agency, 1995a, p. 2).
This indicates that at first glance the issue of
Min-
ing for Closure
may dominantly be an issue for com-
munities and their guardians to pursue. As a Mining
Adviser for the World Bank Group stated some years
ago (Strongman, 2000, emphasis added):
There is a fundamental divide between the in-
terests of mining companies and the interests of
the rationale for working towards
“mining for closure”

23. As such, we are essentially discussing “walk-away” – or legally
binding sign-off of liability for the site. However, as Gilles Trem-
blay, Program Manager, Special Projects with Natural Resources
Canada indicates (personal communication: Natural Resources
Canada, 2005, 2 August)- for sites with ongoing pollution chal-
lenges such as acidic drainage – true “walk-away” conditions may
not be achievable.
