Gold production increased by 2 per cent from 264,400 ounces for
the six months ended 30 June 2018 to 270,900 ounces for the six months ended 30 June 2019 mainly due to higher yield in line with
the plan.
Total tonnes mined, including capital stripping, increased by 7 per
cent from 45.2 million tonnes for the six months ended 30 June 2018 to 48.5 million tonnes for the six months ended 30 June 2019
due to improved contractor fleet performance. Ore tonnes mined
increased by 19 per cent from 6.7 million tonnes to 8.0 million
tonnes. Operational waste tonnes mined increased by 91 per cent
from 10.8 million tonnes to 20.6 million tonnes due to higher operational waste stripping required to expose ore in line with the
2019 plan. Capital waste tonnes mined decreased by 28 per cent
from 27.7 million tonnes to 19.9 million tonnes in line with the 2019
plan. Grade mined decreased by 3 per cent from 1.29 grams per
tonne to 1.24 grams per tonne in line with the 2019 plan. The strip
ratio decreased from 5.7 to 5.1.
The CIL plant throughput increased marginally from 6.88 million
tonnes for the six months ended 30 June 2018 to 6.89 million
tonnes for the six months ended 30 June 2019. Realised yield from
the CIL plant increased by 3 per cent from 1.19 grams per tonne
to 1.22 grams per tonne due to higher grade ore fed from mining
and stockpiles and improved plant recovery which increased from
96.6 per cent to 97.3 per cent.
Cost of sales before amortisation and depreciation, increased by
5 per cent from US$150 million for the six months ended 30 June
2018 to US$157 million for the six months ended 30 June 2019 as
a result of higher operational tonnes mined, partially offset by a
higher gold-in-process credit. The six months ended 30 June 2019
resulted in a US$13 million build-up of stockpiles compared with a
drawdown of US$11 million for the six months ended 30 June
2018.
At the end of June 2019, 5.6 million tonnes at 0.90 grams per tonne
remained on the ROM stockpile and 6.0 million tonnes at 0.64
grams per tonne on the low grade stockpile. At the end of June
2018, 4.8 million tonnes at 0.86 grams per tonne remained on the
ROM stockpile and 4.3 million at 0.64 grams per tonne on the lowgrade
stockpile.
Capital expenditure decreased by 19 per cent from US$84 million
to US$68 million mainly due to lower capital waste stripping and
increased operational waste mined.
All-in sustaining costs and total all-in cost decreased by 1 per cent
from US$954 per ounce for the six months ended 30 June 2018 to
US$940 per ounce for the six months ended 30 June 2019 due to
higher gold sold and lower capital expenditure, partially offset by
higher cost of sales before amortisation and depreciation.

Gold production increased by 25 per cent from 89,500 ounces for
the six months ended 30 June 2018 to 111,800 ounces for the six months ended 30 June 2019 mainly due to higher head grade and
higher volumes processed.
Total tonnes mined, including capital stripping, decreased by 28
per cent from 23.9 million tonnes for the six months ended 30 June 2018 to 17.1 million tonnes for the six months ended 30 June 2019
in line with the 2019 operational plan as the Amoanda pit comes to
completion.
Ore tonnes mined increased by 50 per cent from 1.8 million tonnes
to 2.7 million tonnes. Operational waste tonnes mined decreased
by 21 per cent from 3.4 million tonnes to 2.7 million tonnes as a
result of the Amoanda pit getting deeper with its associated
operational constraints. Total capital waste tonnes decreased by 37 per cent from 18.7 million tonnes to 11.7 million tonnes. Capital
waste of 11.7 million tonnes was mined at the Damang DPCB
complex for the six months ended 30 June 2019. This compared
with 4.4 million tonnes mined at the Amoanda pit and 14.3 million
tonnes at the Damang complex for the six months ended 30 June
2018, comprising 12.4 million tonnes from DPCB and 1.9 million
tonnes from the Saddle area.
Head grade mined decreased by 12 per cent from 1.79 grams per
tonne to 1.58 grams per tonne due to lower grade ore mined from
Saddle pit. The strip ratio decreased from 12.7 to 5.4 in line with
the 2019 operational plan.
Tonnes processed increased by 7 per cent from 2.16 million tonnes
for the six months ended 30 June 2018 to 2.32 million tonnes for
the six months ended 30 June 2019 as a result of higher plant
overall equipment effectiveness and optimisation work carried out
at the crushing circuit. Yield increased by 16 per cent from 1.29
grams per tonne to 1.50 grams per tonne due to higher mined
grade material treated from Amoanda pit. For the six months
ended 30 June 2019, tonnes milled were sourced as follow: 1.92
million tonnes at 1.66 grams per tonne from the pits, 0.40 million
tonnes at 1.78 grams per tonne from stockpiles. This compared
with 1.52 million tonnes at 1.75 grams per tonne from the pits, 0.64
million tonnes at 0.63 grams per tonne from stockpiles for the six
months ended 30 June 2018. The increase in yield
notwithstanding the lower head grade mined is due to the
processing of higher grade stockpiles previously mined at
Amoanda pit.
Cost of sales before amortisation and depreciation, decreased by
6 per cent from US$63 million to US$59 million due to a gold-inprocess
credit to cost of US$7 million for the six months ended 30 June 2019, compared with US$5 million for the six months ended
30 June 2018, as well as lower cost.
Capital expenditure decreased by 32 per cent from US$73 million
to US$50 million, with US$45 million spent on capital waste
stripping.
Sustaining capital expenditure decreased by 43 per cent from
US$7 million to US$4 million due to the expenditure incurred on
the SAG mill shell replacement in the six months ended 30 June 2018. Non-sustaining capital expenditure decreased by 30 per
cent from US$66 million to US$46 million mainly due to lower
capital waste tonnes mined.
All-in sustaining costs decreased by 21 per cent from US$829 per
ounce for the six months ended 30 June 2018 to US$652 per
ounce for the six months ended 30 June 2019 due to higher gold
sold, lower cost of sales before amortisation and depreciation and
lower sustaining capital.
All-in costs decreased by 33 per cent from US$1,585 per ounce
for the six months ended 30 June 2018 to US$1,061 per ounce for
the six months ended 30 June 2019 due to the same reasons
above, as well as lower non-sustaining capital expenditure.
At the end of the June 2019 quarter, and 30 months into the
Damang Reinvestment Project (DRP), total material mined
amounted to 103 million tonnes, 19 per cent ahead of the project
schedule. Gold produced during the same period was 436,185
ounces, 27 per cent above the DRP ounces of 344,332. The
project capital spent to date is US$320 million versus the original
DRP budget to date of US$275 million, largely driven by the
additional capital waste tonnes mined.
