MEDIA RELEASE
GOLD FIELDS DRILLS OUT 1 MOZ MINERAL
RESOURCE AT HAMLET, ST IVES

Johannesburg, 20 May 2010: Gold Fields Limited (Gold Fields)
(JSE, NYSE, NASDAQ Dubai: GFI) is pleased to announce a
substantial increase in the Mineral Resource at Hamlet, an
emerging gold deposit in the Argo-Athena camp at its St Ives Gold
Mine in Western Australia.

Exploration drilling over the past year has led to an increase in
Indicated and Inferred Mineral Resources at the Hamlet deposit,
which is now reported as 6.62 Mt at 4.86 g/t for a total of 1.03
million ounces. The Mineral Resource estimate has been
independently audited by Optiro, a Perth-Based minerals industry
consulting and advisory organisation.

After Athena, Hamlet is the second major discovery in the
developing Argo-Athena camp in the last two years and is the result
of an extensive investment in the St Ives’ near-mine exploration
programme.

*  The Mineral Resource is reported at a nominal 0.60 g/t gold cut-off grade, for
shallow resources, constrained within an optimised pit shell and 2.4
g/t cut-off for
the underground resources within conceptual stope shapes. It is expected that the
majority of the resource will be mined by underground methods. The pit shell is
based on price assumptions of US$1,150/oz (A$1,375/oz) gold. The Mineral
Resource estimate is reported in accordance with the South African Code for the
Reporting of Exploration Results, Mineral Resources and Mineral Reserves, 2007
Edition (SAMREC Code) and is reported without unplanned dilution or ore loss.


The Hamlet deposit is located approximately 1km to the east of the
new Athena underground mine and 12km south of the Lefroy Mill.
Athena and Hamlet are part of a larger mineralised system in the
Argo-Athena camp, which is being actively explored by the near
mine exploration team.

“This milestone highlights the potential of the developing Argo-Athena camp, which now has an
estimated endowment
1 of about 4 Moz, and is a credit to the excellent work done by the near mine
exploration team,” commented Nick Holland, Chief Executive Officer of Gold Fields.

An initial Indicated and Inferred Mineral Resource for the Hamlet Deposit of 2.1 Mt at 3.65 g/t for
251 Koz was reported in Gold Fields’ Mineral Resource and Mineral Reserve declaration for the 2009
financial year. Drilling since July 2009 has focussed on shallow mine-definition and extensional
drilling aimed at defining the size and content of the deposit. A total of 41,900m of RC (reverse
circulation) drilling and 45,700m of diamond core drilling was completed in 10 months. The deposit
consists of an upper and lower lode; the lodes have been defined over 600m of strike and to a
vertical depth of 800m. The deposit remains open at depth. Drilling to further expand the resource
and support a feasibility study is underway and a construction decision is planned for the first half of
calendar 2011.

Gold Fields recently intersected the first ore on the margins of the main ore body in underground
development at the new Athena mine. The decline and mine development are progressing on time
and within budget and full production remains on schedule for mid-calendar 2011. The Athena
infrastructure, currently under development, was positioned to provide a potential underground
access to the Hamlet deposit, which would enable the rapid development of the project on
completion of a successful feasibility study.
