Growth
Gold Fields has set a target of achieving five million ounces
per annum, in production or in development, by the end of
2015. To this end we are developing an extensive pipeline of
projects which is discussed below.
International Projects
Chucapaca
Sterilisation drilling for the alternate tailings and waste storage
areas continued and is forecast to be completed by the end of
2012 pending agreements with the local Oyo Oyo community.
Negotiations with the local communities are on-going and
focus on land acquisition options for the project.
Work continued in all areas towards completion of the
feasibility study and submittal of the Environmental Impact
Assessment (EIA) by the end of 2012. Recent focus has been
on project peer reviews and final optimisation of project
parameters.
On completion of the feasibility study a period of value
engineering is planned to optimise the project capital costs
and ore recoveries. This value engineering will be conducted
in parallel with land acquisition and EIA processes.
Far Southeast
Following re-establishment of the underground drilling
platforms in the March quarter, activity continued with nine
drills out of a planned twelve completing a total of 17,000
metres of drilling in the June quarter. Two surface drill rigs
have commenced geo-technical drilling and, together with the underground drilling will provide additional data for the on-going
pre-feasibility study and maiden resource for this
project.
Pre-feasibility studies investigating mine access strategies,
production rates and scale, and metallurgical processing
commenced during the quarter. Various tailings storage
facility sites are under investigation, considering technical,
social and environmental perspectives.
Our Foreign Technical Assistance Agreement (FTAA)
application, which allows for direct majority foreign ownership
and control, was submitted in November 2011 and requires
Free Prior Informed Consent (FPIC) of the Indigenous People
in our affected areas. The FPIC process was suspended at a
national level pending the release of new guidelines, which
have subsequently been released. The process is expected to
recommence in the September quarter, with FPIC anticipated
to be received in 2013.
In July 2012, after months of consultation with key
stakeholders, President Aquino issued an Executive Order
providing policies and guidelines to ensure responsible mining
and utilisation of mineral resources in the Philippines. The
Executive Order is a policy statement and will be further
clarified by the Implementing Rules and Regulations
scheduled for release within 60 days. Our initial assessment
of this policy statement suggests that this will have no
significant effect on the FSE project, however we can only
confirm this once the Rules and Regulations are released.
The material sections of the Executive Order include:
- enforcement of environmental standards in mining with
reviews of existing operations;
- rationalisation of existing revenue sharing schemes and
arrangements, which we do not expect will have any
significant impact on the FTAA fiscal regime as the
FTAA currently provides for a 50:50 government sharing
and is competitive by international standards;
- suspension of the granting of new mineral agreements
until the fiscal sharing arrangements are rationalised and
legislated. We note that the Government has verbally
clarified however that this moratorium does not preclude
the negotiation of FTAAs for future mining projects. We
will not be affected by this provision as our FTAA
application was submitted prior to the issuance of the
Executive Order;
- implementation of measures to ensure alignment of
national interest with local governments’ interests; and
- implementation of measures to improve regulation and
control of small scale mining activities.
Arctic Platinum
Work continued on the pre-feasibility study and the definition
of a maiden resource for the Suhanko North project after
drilling was completed in the March quarter. All outstanding
assays were completed and the geological model and
resource estimates are expected to be completed by year-end.
Mine optimisation studies and a preliminary production model
for Suhanko North will be added to existing Suhanko
information to develop a series of trade-off options between
Konttijarvi, Ahmavaara and Suhanko North, the three Suhanko pits.
Initial metallurgical test work, including the Platsol
downstream process option, for Suhanko North is complete,
and plans for detailed test work are underway. Work has
commenced to collect baseline data related to Suhanko
North, for inclusion in the EIA permitting process. Marketing
studies for various products are advancing.
Damang super-pit
Drilling commenced on an interim 23,000 metre infill
campaign and 5,918 metres were completed during the
quarter. This drilling programme is expected to be completed
by the end of the year.
Greenfields exploration
In addition to the four resource development projects
mentioned above, the greenfields exploration portfolio also
consists of three advanced drilling projects, fifteen initial
drilling projects and six target definition projects in Peru,
Chile, Argentina, Ghana, Mali, Guinea, Canada, Kyrgyzstan,
China, Australia and the Philippines. A total of 55,478 metres
was drilled on ten greenfields projects during the quarter
compared with 99,800 metres drilled in the March quarter and
62,813 metres in the June 2011 quarter. The main reason for
the lower level of drilling activity in the June quarter was the
onset of winter in the Andes and seasonal rainfall in Australia
and Africa.
Africa
Following a short hiatus in the aftermath of the coup d’état in
Mali in late March 2012, diamond and reverse circulation
drilling resumed at the Yanfolila advanced drilling project in
mid-April 2012. The drills focused on infilling anomalies and
structures previously defined at the Gonka, Kabaya South and
Sanioumale West prospects. A total of 8,131 metres of
reverse circulation drilling was completed during the quarter.
The Komana scoping study will be updated with the additional
data in the September quarter. Drilling programmes also
continued this quarter on the Kangare project in Mali and at
the Asheba project in Ghana. Target definition work
consisting of geochemical surveys and geological mapping is
in progress at the Boako project in Ghana and over a number
of additional concessions with the extensive Kangare project
area in Mali.
North America
Diamond drilling resumed at the Woodjam advanced drilling
project in British Columbia in March 2012 and two drills are
currently active. Results are encouraging from initial drill
holes at one new target area and a follow-up programme will
be implemented in the September quarter.
Gold Fields executed an agreement with Bear Lake Gold on
its Larder Lake project in Ontario and diamond drilling
commenced in June 2012. Five diamond drill holes were also
completed at the Marble Mountain project in Ontario in May
2012, representing first activity on this new property. A
decision on the way forward will be made once all the results
have been analysed.
South America
With the onset of winter in the high Andes, drilling
programmes at the Salares Norte project in Chile and the
Taguas project in Argentina were concluded during the June
quarter. Results from both of these initial drilling projects
were encouraging and drilling is expected to resume in
September 2012. Drilling continues on two early stage
projects in southern Peru.
Australasia
Gold Fields’ drilling projects continued in the East Lachlan
region of New South Wales, Australia. Progress at the Myall
project was hampered by heavy rains and the remainder of
the drilling programme has been postponed until the
December quarter. At the Wellington North project, two drills are currently active at the Mayhurst target and results
continue to be positive.
Other regions
In north-western Kyrgyzstan, Gold Fields owned a 60 per cent
interest in the Talas joint venture with partner Orsu Metals
Corporation. Subsequent to quarter end, the Group acquired
the outstanding 40 per cent and now fully owns Talas. A
6,000 metre diamond drilling programme commenced in April
2012 after a two year hiatus following civil unrest in the
country. The 2010 scoping study will be updated with results
from the current drilling campaign and will form the basis
whether to proceed to pre-feasibility by the end of 2012.
Near mine exploration
Gold Fields has a well-supported near mine exploration
programme, successfully replacing production and growing
the reserve base at the international operations. Exploration
success immediately adds valuable life-of-mine to these
established assets which forms the sustaining foundation of
our overall growth strategy.
In Ghana, near mine exploration at Damang outside of the
super-pit project has been limited to modelling of recent data
acquired from drilling in the Amoanda-Rex corridor trend.
This will be ongoing with results expected in the second half
of 2012.
In Peru, at Cerro Corona, drilling commenced on the Corona
Deep programme highlighted in the March quarter. The 7,300
metres drill programme, targeting potential depth extensions
below the current planned open pit limits should be concluded
by the end of 2012.
In Australia, the 2012 A$35 million exploration programme at
St Ives is on schedule. Drilling continues to expand the
inventory in the area between Revenge and Neptune,
including definition of the southern extension of the N01
structure at Revenge that produced almost 300,000 ounces
by underground mining methods. Expanded early stage
exploration delineated several encouraging new prospects
including Invincible in the Greater Santa Ana area and Target
X in the Leviathan area. High grade mineralisation continues
to be intersected on depth extensions of the Eastern Lodes at
Cave Rocks.
Drilling continued on the high grade shoots project at Agnew
targeting the down-plunge of Main Lode at the Waroonga
complex. This programme, which initially confirmed the
presence of high grade mineralisation, is now confirming the
continuity and extent of the higher grade shoots.
