GOLD FIELDS AND OUTOKUMPU ANNOUNCE NEW PGE RESOURCES OF 5.1 MILLION OUNCES IN
THE SK REEF AT ARCTIC PLATINUM PARTNERSHIP
11 February, 2002; Johannesburg, South Africa and Espoo, Finland: Gold Fields
Limited (JSE: GFI and NASDAQ: GOLD) and Outokumpu Oyj (HEX: OUT) are pleased to
announce new platinum group element ("PGE") resources of 5.1 million ounces at
their Arctic Platinum Partnership ("APP") in Finland. These resources, in
addition to the PGE resources announced last year, bring the total of measured,
indicated and inferred resources at APP to greater than 11 million ounces. Gold
Fields Limited completed its 51 % earn-in acquisition in the partnership on
January 17,2002.
The SK Reef occurs as a stratiform PGE reef in the Narkaus Intrusion of the
Portimo layered complex situated in northern Finland. The reef has been traced
in outcrops and through shallow drilling over a strike length of 10km. Last year
APP completed systematic drilling over an aggregate strike length of
approximately 6 km in three areas known as Siika Kama, Nutturalampi and
Kuohunki.
The resource estimated for the SK Reef is 5.1 million ounces contained in 30Mt
at an average grade of 5.2 g/t 2PGE+Au (3.9 g/t Pd, 1.1 g/t Pt, 0.2 g/t Au),
plus 0.14 %Cu and 0.11 %Ni. In the following Table the resource in each area is
reported above a cutoff of 2.0 g/t 2PGE+Au to an average depth of 260 metres. At
a cutoff of 0.5 g/t the estimate is 5.3 million ounces contained in 35Mt at an
average grade of 4.7 g/t 2PGE+Au.

The Mineral Resource estimate was undertaken by Snowden Mining Industry
Consultants and is classified as Inferred in accordance with the JORC Code
(September 1999). The Code is a recognized standard of Mineral Resource and Ore
Reserve reporting.
The Siika Kama, Nutturalampi and Kuohunki geological models and resource
estimates are based on a total of 16,700 metres of drilling, comprising 4,200
metres of earlier drilling by Outokumpu and 12,500 metres of drilling by APP.
Drilling was carried out on grid lines spaced 200m apart.
The SK Reef dips at 20 - 40degrees with an average of 30degrees . Good
structural and mineralization continuity has been demonstrated by drilling which
has tested the reef to a maximum depth of 300 metres.
The drilled sections of SK Reef have an average reef thickness of 4.9 metres.
Additional PGE mineralization occurs above and below the reef and can extend up
to 15m into mineralized footwall gabbro. This additional mineralization is not
included in the current resource estimate.
Initial metallurgical studies on SK Reef ore types have been completed with
positive results, as part of an ongoing scoping study. The study is assessing a
stand alone SK Reef mining operation and the impact of milling higher grade SK
Reef material as supplementary ore to the Suhanko project, which envisages open
pit mining at the Konttijarvi and Ahmavaara deposits located 20 - 30 km away. A
feasibility study is in progress on the Suhanko project, as well as exploration
to expand the 6.0 million ounce PGE resource announced from Konttijarvi and
Ahmavaara in July 2001. A summary of APP resources reported above 0.5 g/t
2PGE+Au cutoff follows:
