REVIEW OF OPERATIONS: WEST AFRICA REGION
Damang Gold Mine
 |
Fatality free year. |
 |
Increased gold production. |
|
OVERVIEW
Location: Damang is located in southwestern
Ghana, approximately 300 km by road, west
of Accra, the capital, at a latitude 5°11’N and
longitude 1°57’W. It is situated some 30 km
north of the town of Tarkwa with reasonable
access roads and an established infrastructure.
The mine is served by a main road connecting
to the port of Takoradi, some 90 km to the
southeast. Infrastructure: Multiple open pits,
surface stockpile sources and a CIL plant.
Geology: The Damang Gold Mine exploits
oxide and fresh hydrothermal mineralisation in
addition to Witwatersrand style, palaeoplacer
mineralisation similar to that of the Tarkwa Gold
Mine. Employees in service: 407 permanent
employees, 1,101 contractors.
SAFETY AND ENVIRONMENT
Damang Gold Mine experienced another good
safety year and the mine remains fatality free
since acquisition by Gold Fields. The mine has
shown an improvement in safety, evident in the
Lost Day Injury Frequency Rate improving from
0.68 to 0.37. This achievement has earned
the mine the prestigious Chairman’s Award for
the best safety improvement over a three year
period.
The mine’s safety management system has
been OHSAS18001 certified since 2006 and
re-certification was achieved following an
external audit conducted in May 2009. Damang
also retained its ISO14001:2004 (Environmental
Management System) certification following an
external audit during the year, and remains fully
compliant to the ICMI Cyanide Code.
OPERATIONAL REVIEW
Gold produced increased by three per cent from
194,000 ounces in F2008 to 200,000 ounces
in F2009. This was due to the build up of the
crushed ore stockpile in F2008, which resulted
in a consistent feed to the mill in F2009. Thus,
tons milled increased from 4.52 million tons in
F2008 to 4.99 million tons in F2009.
Tons mined decreased from 31.4 million tons
to 19.5 million tons as a result of mining the
deeper, higher-grade Damang pit cutback. Ore
mined increased from 4.1 million tons in F2008
to 4.4 million tons in F2009.
Revenue increased from US$160 million in
F2008 to US$176 million in F2009 resulting from
the higher gold price received and increased
production.
Operating costs, including gold-in-process
movements, increased by 20 per cent from
US$108 million in F2008 to US$130 million
in F2009. This increase was mainly due to
increased mining of the more expensive
Damang pit cutback and increased mill
consumable costs.
Total cash cost increased from US$551 per
ounce in F2008 to US$660 per ounce in F2009
as a result of the higher costs.
Operating profit, before amortisation, decreased
from US$53 million in F2008 to US$46 million
in F2009. Operating margin decreased from
33 per cent in F2008 to 26 per cent in F2009.
Capital expenditure decreased from
US$28 million in F2008 to US$17 million
in F2009. The decrease was mainly due to
higher Damang pit cutback development
costs in F2008. The majority of expenditure in
F2009 was for upgrading the primary crusher,
exploration drilling and developing the Rex pit.
Notional cash expenditure decreased from
US$753 per ounce in F2008 to US$745 per
ounce in F2009.
F2010 Focus Areas
- The operational focus will be on acquiring
and installing a secondary crusher,
maintaining plant efficiencies, and
optimising throughput volumes.
- With renewed focus on growing Damang,
the F2010 drilling campaign is targeting
27,600 metres of reverse circulation and
17,250 metres of diamond drilling at a
total estimated cost of US$10 million.
