A word from the owner :
Alusaf Limited

Core owner's team to expand Alusaf's production
capacity by building the 466 ktpa greenfield Hillside
Smelter.

US $ 2 billion

Expected to take 36 months, but completed in 31
months.

Pechiney AP28/30 technology.

Plant consumes 840 Megawatts of continuous
power, equivalent to the total consumption of Cape
Town and Port Elizabeth - ESKOM's largest
customer by far!

Comprehensive EIA completed September 1992,
including public response reports.  Forerunner of
most current day SA large project EIA's.

Producing 500 ktpa of aluminium ingots.

It is the world's largest greenfield aluminium
smelter.

A word from the owner :
Reunion Mining and later Anglo American plc, Base
Metals Division.

25km north of Rosh Pinah, Southern Namibia.

US $ 450 million.

• Zinc Oxide orebody discovered in 1976 (Anglo American
  Corporation).
• Bankable feasibility study and piloting carried out in 1998
  (GTI).
• Anglo American approved the project in 2000.
• Project completed in 2003.

To produce a world class integrated zinc mine and refinery
that sets the highest standards in the innovative processing
and production of low-cost Special High Grade zinc.

First application of zinc solvent extraction technology on a
primary orebody.  Zinc is leached from the oxide ore with
sulphuric acid at atmospheric pressure.
Zinc is extracted from the leach solution by solvent
extraction and stripped from the organic by spent
electrolyte.  The loaded electrolyte is sent to the electro-
winning cellhouse where Special High Grade zinc
(99.995%) is produced and finally cast into products for
export.

• Single circuit 400kV overhead line 260km Keetmanshoop
  to Skorpion.
• 25% of Namibia's total power requirements, with a plant
  maximum demand of 84 Megawatts.

Skorpion was developed in a unique and fragile ecosystem
where the slightest disturbance can blow away countless
dormant seeds of the endemic desert flora or affect the
habitats of unique wildlife. Many species of rare and
unusual plants were removed prior to earthmoving. The
Skorpion team also developed a comprehensive emissions
monitoring programme.
Remote and environmentally sensitive site . One of the
world's top 25 biodiversity hotspots. Environmental Impact
Assessment completed to World Bank standards. Environ-
mental Management Plan implemented during construction
paved the way for operational ISO 14001 listing, IAIAsa
project of the year winner.

Infrastructure  included 191 houses, a shiftworkers village,
airstrip and water supply from the Orange River, 45km
away.

At full capacity the refinery will produce 150 ktpa of high
quality zinc.  The plant has a lifespan of 15 years with ore
reserves at 21,4 million tonnes.

Classic Business 8/8/03 - "We're very pleased with the
commissioning of the Skorpion Zinc Project in Namibia.  It's
gone very well.  It looks to be a very good business and a
very low cost producer." Tony Trahar, CEO, AAplc.

Special Requirements :
Metalline Mining Company, Idaho, USA.

To produce a bankable feasibility study for a zinc mine
and refinery complex in Coahuila province, Mexico.

Control budget estimate to be produced by the study.

The deposit consists of two resources, each a different
mineral system separated by the east west trending
Sierra Mojada fault. North of the fault the mineralisation
is chemical sedimentary disseminated to massive silver,
copper, zinc and lead sulphide. South of the fault the
mineralisation consists of oxide zinc and lead manto
deposits.

Zinc Solvent Extraction and Electrowinning process
(SXEW) supplied by Tecnicas Reunidas, Madrid Spain.
The Red and White Zinc Manto ore bodies at Sierra
Mojada are oxide zinc and SXEW may give Metalline a
30% cost of production advantage over sulphide ore
producing competitors.The solvent extraction process
consists of leaching the oxide zinc ore with sulphuric
acid producing an acidic solution containing zinc and
other soluble metals, the leach solution. The leach
solution is mixed with the organic extraction solution,
which selectively removes and concentrates zinc from
the leach solution into the organic extraction solution.
The extraction solution is taken to electrolytic reduction
cells where SHG zinc (99,995%) is produced.

Negotiations in progress with Comison Federal de
Electricidad of Mexico.

Area mined for silver for past 60 years - environmental
baselining in progress.
