Gold production decreased by 4 per cent from 111,200
ounces in the June quarter to 106,600 ounces in the
September quarter in line with the current mine schedule.
At the underground operations, ore mined increased from
320,000 tonnes at 5.6 grams per tonne in the June quarter to
354,000 tonnes at 5.4 grams per tonne in the September
quarter. This was as a result of increased tonnage from the
slightly lower grade Cave Rocks.
At the open pit operations, total ore tonnes mined decreased
marginally from 1.21 million tonnes at 1.5 grams per tonne in
the June quarter to 1.19 million tonnes at 1.4 grams per tonne
in the September quarter. The transition to owner-operator
has commenced, with A$21 million of mobile equipment
purchased during the quarter and A$31 million expended on
the project to date. The total cost of the project is anticipated
at A$92 million by completion date in 2014.
Total tonnes processed increased from 1.76 million tonnes at
a yield of 2.0 grams per tonne in the June quarter to 1.85
million tonnes at a yield of 1.8 grams per tonne in the
September quarter. Throughput at the Lefroy mill increased
from 1.19 million tonnes to 1.23 million tonnes, partly
offsetting the lower yield which decreased from 2.7 grams per
tonne to 2.5 grams per tonne, reflecting the reduced grade
milled from all ore sources. Gold production from the Lefroy
plant decreased from 104,100 ounces to 100,600 ounces.
At the heap leach facility, tonnes processed increased from
566,000 tonnes at a head grade of 0.69 grams per tonne in
the June quarter to 623,000 tonnes at a head grade of 0.68
grams per tonne in the September quarter. However, due to
recovery times at the heap leach operation gold production
decreased from 7,100 ounces to 6,000 ounces.
Operating costs, including gold-in-process movements
decreased from A$103 million (R837 million) in the June
quarter to A$96 million (R822 million) in the September
quarter. The decrease in costs was due to a smaller
drawdown of stockpiles, compared with the June quarter and
reduced open pit costs. Total cash cost decreased from
A$908 per ounce (US$920 per ounce) to A$890 per ounce
(US$922 per ounce) due to the lower operating cost.
Operating profit at A$74 million (R636 million) in the
September quarter was similar to the A$76 million (R617
million) recorded during the June quarter.
Capital expenditure increased from A$74 million (R606
million) to A$99 million (R833 million) due to increased
expenditure on Bellerophon and Hamlet mine development
and infrastructure, as well as the purchase of open pit mobile
equipment due to the transition to owner-mining.
Notional cash expenditure increased from A$1,561 per ounce
(US$1,581 per ounce) in the June quarter to A$1,813 per
ounce (US$1,879 per ounce) in the September quarter due to
the increase in capital expenditure and decrease in
production. The NCE margin decreased from 3 per cent to a
negative 13 per cent as a result of the higher NCE in the
September quarter. Once capital, costs and production reach
steady state during calendar 2013 the NCE is expected to be
maintained at around A$1,250 per ounce.

Gold production increased by 28 per cent from 37,200 ounces
in the June quarter to 47,600 ounces in the September
quarter.
Ore mined from underground increased from 153,000 tonnes
at a head grade of 7.9 grams per tonne to 191,000 tonnes at a head grade of 8.5 grams per tonne. This increase in tonnes
and grades was mostly from the high grade Kim mine in
accordance with the revised mining schedule for the second
half of the year.
Tonnes processed increased from 255,000 tonnes in the June
quarter to 265,000 tonnes in the September quarter, which
included 77,000 tonnes of surface stockpile material
processed from Songvang compared with 110,000 tonnes in
the June quarter. The combined yield increased from 4.5
grams per tonne in the June quarter to 5.6 grams per tonne in
the September quarter reflecting the increase in higher grade
underground tonnes. The yield from the Songvang ore was
similar quarter on quarter at 1.5 grams per tonne.
Net operating costs, including movements in gold-in-process,
were similar to the June quarter at A$35 million (R300
million). Total cash cost decreased from A$916 per ounce
(US$928 per ounce) to A$727 per ounce (US$754 per ounce)
mainly due to the increased gold production.
Operating profit increased from A$24 million (R199 million) in
the June quarter to A$40 million (R341 million) in the
September quarter as a result of the 28 per cent increase in
gold production.
Capital expenditure decreased from A$21 million (R173
million) in the June quarter to A$15 million (R124 million) in
the September quarter. Capital expenditure included A$8
million on underground development and A$5 million on
exploration. The decrease in expenditure in the September
quarter was due to A$5 million spent on additional mining
equipment in the June quarter.
Notional cash expenditure decreased from A$1,507 per ounce
(US$1,526 per ounce) in the June quarter to A$1,078 per
ounce (US$1,117 per ounce) in the September quarter, as a
result of the increased gold production and the lower capital
expenditure. The NCE margin increased from 6 per cent to
32 per cent due to the lower NCE.
