Expansion of Bulyanhulu Upper East Project and order of long lead items
* Incorporation of Reef 2 ounces brings total project in excess of 2Moz
* Incremental additional production will average over 90koz per annum
* Board approved order of long lead items, production targeted for Q4 2014
* Project generates a post tax IRR of 34% at current gold prices
ABG has continued to progress the acceleration of mining of the Upper East Zone
at Bulyanhulu and has received Board approval to begin the ordering of certain
long lead items for the project. The project was previously solely based on the
1.2 million ounces (Moz) of reserves located in Reef 1 of the Upper East Zone,
and we have now completed a positive scoping study to incorporate the 900,000
ounces (koz) of gold which currently sit in reserves in Reef 2 of the Upper
East zone. We are now progressing with pre-feasibility and feasibility work on
Reef 2 with the aim of completing a combined feasibility study for both reefs
by the end of Q1 2013. Production from the Upper East Zone is targeted to
commence in late 2014 and is now expected to average in excess of 90koz per
annum over the life of mine ("LOM") at average cash costs of $608 per ounce.
The incorporation of Reef 2 significantly enhances the project economics,
driving a post tax IRR of 34% at $1,700 per ounce. The project is estimated to
require approximately $100 million of pre-production capital, to be spent in
2013 and 2014 and is planned to deliver life of mine production of 1.86Moz over
the next 20 years.
Commenting on the project, CEO Greg Hawkins said: "One of our key aims for this
year is to progress the expansion of Bulyanhulu in order to accelerate the
realisation of the value provided by the scale of the reserve base. In May we
received Board approval for the CIL expansion, and we have now successfully
expanded the scope of the Upper East Project whilst maintaining our planned
timeline for first production. With the two expansion projects, we now have a
clear path to increasing production levels at Bulyanhulu towards 400,000 ounces
per annum over the coming years."

Background to the project:
Bulyanhulu is a world class high grade underground mine with reserves of
10.6Moz at a grade of 11.7g/t Au and total resources of 16.9Moz at 9.7g/t Au
and in 2011 the mine produced 262koz. Production rates are currently
constrained by the hoisting capacity of the shaft resulting in a mine life of
over 25 years. As part of our drive to optimise our assets, ABG has been
examining options to increase mining rates from Bulyanhulu to bring production
more into line with the scale of the resource base.
A key part of the analysis has been the Upper East zone which is situated
approximately 1.5km east of the process plant, on the eastern extension of the
strike length of the mine. The zone is currently included in reserves and was
scheduled to be mined later in the mine life. The Upper East was initially
accessed in 2001 through a 1.8km decline from the central ramping system. Due
to the low gold price environment the area was subsequently not developed. Over
the past 18 months ABG has been dewatering and rehabilitating the decline as it
provides an opportunity to truck ore to surface and therefore bypass the shaft
constraint.
ABG initially examined the opportunity to bring forward just the ounces
contained in Reef 1 (1.2Moz at 10.6 g/t Au) and have completed a feasibility
study into the project, which is awaiting the completion of a test stope before
being submitted for Board approval. As previously announced, we are
investigating the possibility of mining Reef 2 in parallel with Reef 1, which
will allow increased access to mining faces and therefore increase production
rates from the zone while using the same ramp system. The incorporation of Reef
2 adds 0.9Moz at 9.7g/t Au to the project, bringing the total reserve ounces
contained in the Upper East Zone project to 2.1Moz at 10.2g/t Au.
ABG has commenced work on a pre-feasibility and feasibility study to
incorporate the mining of Reef 2 in parallel with Reef 1 which will utilise the
shared underground infrastructure. Reef 2 is hosted in a more competent host
rock and therefore it is planned to utilise lower cost mining methods already
employed elsewhere at the mine, namely long hole stoping. We estimate this work
will be completed by the end of Q1 2013 after which time Board approval will be
sought for the whole project. In order to protect the overall timeline to first
production, the Board have approved the ordering of certain long lead items to
ensure that mining operations can commence once Board approval is received. All
equipment ordered ahead of final Board approval can also be utilised in the
existing Bulyanhulu operations. The commitment amounts to $4.3 million in 2012
and $6.5 million in 2013.
With the incorporation of Reef 2 into the project, it is now expected to be of
sufficient scale to become a standalone operation and benefit from having its
own dedicated infrastructure, ventilation and personnel in place.
Sensitivity Analysis:
The sensitivity analysis below highlights the returns the project offers at a
range of gold prices:
Gold price $/oz 1,200 1,400 1,700 1,800
Post tax IRR % 17.1% 24.1% 34.3% 37.7%
Desktop rescheduling of the life of mine plan has shown the ability to fully
replace the Upper East ounces in the current mine plan whilst still maintaining
the existing production profile and therefore the whole of the Upper East zone
project provides incremental value to the mine.
Key Life of Mine Operating Metrics:
The key life of mine operating metrics are based upon a combination of the
feasibility study on Reef 1 and the scoping study on Reef 2. This combination
of studies in conjunction with the recently approved CIL Expansion Project
gives the potential to move from 92% to 95% recoveries from the Bulyanhulu
Upper East ore. The studies show a lower cash cost than current levels, given
Upper East is closer to surface and will mine material with grades similar to
current Bulyanhulu operating averages. The ordering of the long lead items
provides the opportunity to bring forward production from 2015 to Q4 2014.

Next Steps:
We plan to implement the project in two phases. Phase One will commence
immediately with the ordering of the long lead items. Following completion of
the combined feasibility study and upon receipt of Board approval project
development will commence in H1 2013 utilising the dewatered and rehabilitated
1.8km existing decline to provide access for development of stoping areas.
Phase Two is expected to commence in early 2014, once environmental approvals
have been granted for ABG to undertake a box cut over the shallower portion of
the Upper East zone. The box cut will be the location for asecond decline into
the underground which will be developed in order to open up the shallower
reserves on reefs 1 and 2. This box cut will allow for an additional
ventilation intake, improved access to the Upper East reefs 1 and 2 and
additional truck haulage ability through the new ramp system.
A drill programme is continuing on the Upper East to further test the strike
extension and to look to convert additional resources into reserves. Initial
results have been positive and the programme is expected to be completed by the
end of 2012 with the results then being incorporated into the project.
Primary development will be contracted out to a suitably capable development
contractor which will allow the primary workforce to focus on existing
operations.
In tandem with the development, work will commence to increase the capacity of
the front end of the process plant by 200ktpa bringing capacity to around
1.4Mtpa, ABG believes that this can be achieved with limited capital spend and
no impact on operations.
