Adjusted gross margin:
Adjusted gross profit (loss) divided
by gold sales including realised non-hedge derivatives.
Adjusted gross profit (loss):
Gross profit (loss) excluding
unrealised non-hedge derivatives and other commodity
contracts.
Adjusted headline earnings (loss):
Headline earnings (loss)
excluding unrealised non-hedge derivatives, fair value
adjustments on the option component of the convertible
bond, fair value gain (loss) on interest rate swap,
adjustments to other commodity contracts and deferred
tax thereon.
Available-for-sale financial asset:
A financial asset that has
been designated as available-for-sale or a financial asset
other than those classified as loans and receivables, held-
to-maturity investments or derivative instruments.
Average number of employees:
The monthly average
number of production and non-production employees and
contractors employed during the year, where contractors
are defined as individuals who have entered into a fixed-
term contract of employment with a group company or
subsidiary. Employee numbers of joint ventures represents
the group's attributable share.
BIF:
Banded Ironstone Formation. A chemically formed
iron-rich sedimentary rock.
By-products:
Any products that emanate from the core
process of producing gold, including silver, uranium and
sulphuric acid.
Calc-silicate rock:
A metamorphic rock consisting mainly of
calcium-bearing silicates such as diopside and
wollastonite, and formed by metamorphism of impure
limestone or dolomite.
Capital expenditure:
Total capital expenditure on tangible
assets which includes stay-in-business and project capital.
Carbon-in-leach (CIL):
Gold is leached from a slurry of gold
ore with cyanide in agitated tanks and adsorbed on to
carbon granules in the same circuit. The carbon granules
are separated from the slurry and treated in an elution
circuit to remove the gold.
Carbon-in-pulp (CIP):
Gold is leached conventionally from a
slurry of gold ore with cyanide in agitated tanks. The
leached slurry then passes into the CIP circuit where
carbon granules are mixed with the slurry and gold is
adsorbed on to the carbon. The granules are separated
from the slurry and treated in an elution circuit to remove
the gold.
Cash flow hedge:
A hedge of the exposure to variability in
cash flows, that is attributable to a particular risk
associated with a recognised asset or liability or a
forecasted transaction.
Comminution:
Comminution is the crushing and grinding of
ore to make gold available for treatment. (See also
“Milling”).
Contained gold:
The total gold content (tons multiplied by
grade) of the material being described.
Cut-off grade (surface mines):
The minimum grade at
which a unit of ore will be mined to achieve the desired
economic outcome.
Depletion:
The decrease in quantity of ore in a deposit or
property resulting from extraction or production.
Development:
The process of accessing an orebody
through shafts and/or tunnelling in underground mining
operations.
Discontinued operation:
A component of an entity that,
pursuant to a single plan, has been disposed of or
abandoned or is classified as held-for-sale until conditions
precedent to the sale have been fulfilled.
Doré:
Impure alloy of gold and silver produced at a mine to
be refined to a higher purity, usually consisting of 85% gold
on average.
Electro-winning:
A process of recovering gold from solution
by means of electrolytic chemical reaction into a form that
can be smelted easily into gold bars.
Elution:
Recovery of the gold from the activated carbon into
solution before zinc precipitation or electro-winning.
EBITDA:
Operating profit (loss) before amortisation of
tangible and intangible assets, impairment of tangible and
intangible assets, profit (loss) on disposal of assets and
investments and unrealised non-hedge derivatives, plus the
share of associates' EBITDA, less profit (loss) from
discontinued operations.
Effective tax rate:
Current and deferred taxation as a
percentage of profit before taxation.
Equity:
Shareholders' equity adjusted for other
comprehensive income, actuarial gain (loss) and deferred
taxation. Where average equity is referred to, this is
calculated by averaging the figures at the beginning and
the end of the financial year.
Financial asset:
Cash or cash equivalents, an equity
instrument, a contractual right to receive cash, or a
contractual right to exchange a financial instrument under
