FACTBOX-Teck Resource’s Red Dog mine

March 17 (BestGrowthStock) – Teck Resources (TCKb.TO: )(TCK.N: ) is
facing an appeal by native and environmental groups of a planned
expansion of its Red Dog zinc mine in Alaska, the largest zinc
mine in the world.

The environmental permits cover the Aqqaluk deposit, to
which Teck intends to gradually shift mining this year, as the
current deposit is expected to be depleted in 2011.

Teck has said any delay beyond May will likely force it to
stop production in October, as it needs ore from Aqqaluk to
supplement the declining grades of the remaining ore in the main
deposit.

Below are key facts of the Red Dog mine:

OWNERSHIP:

* While Red Dog operated by Teck, the land is leased from
the NANA Regional Corporation, which is a native Alaskan
development corporation.

PRODUCTION:

* The open-pit mine produced 582,500 tonnes of zinc
concentrate and 131,500 tonnes of lead concentrate in 2009.

* The concentrates are shipped to Teck’s smelter in Trail,
British Columbia, as well as to customers in Asia and Europe.

* Red Dog accounts for about 80 percent of zinc mined in the
United States. About half of the product is used for galvanizing
steel, while the rest is used in zinc-based alloys, to create
brass and bronze, as well as in agriculture, chemicals, paint
and rubber.

* The mine also accounts for almost 30 percent of the lead
concentrate mined in the United States, most of which is used in
the battery industry.

THE NEW DEPOSIT:

* The Aqqaluk ore body, located adjacent to the original Red
Dog pit, is expected to effectively double the lifespan of the
mine, which opened in 1989. The deposit holds 51.6 million
tonnes of proven and probable reserve grading 16.7 percent zinc
and 4.4 percent lead.

THE OPPOSITION:

* The expansion has the backing of Alaska’s political and
business establishment, but environmentalists have said the mine
has inflicted years of harm on the fragile Arctic environment.

* Environmentalists point to studies finding that harvests
of caribou and beluga in the vicinity of the mine have fallen to
less than half of pre-mine levels.

* Red Dog has been cited in the past by federal and state
regulators for improperly releasing sediments and metals into
the water and air.

* Most recently, Teck agreed in September to pay $120,000 to
settle a series of wastewater discharge violations alleged by
the EPA.

THE CHALLENGE:

* Several environmental and tribal groups have appealed a
renewed National Pollution Discharge Elimination System (NPDES)
permit, which was due to come into effect on March 1.

* The U.S. Environmental Protection Agency is expected to
issue a notice clarifying which specific parts of the permit are
subject to appeal, but until that happens, the entire permit is
on hold.

* The appeal was filed on Feb. 17, and the EPA usually
issues its notice with 30 days of an appeal.
