St Barbara is now a diversified, international, mid tier gold producer
Overview
On 7 September 2012, St Barbara gained control of the Allied Gold Mining Plc group and the Pacific Operations of Simberi in Papua New Guinea, and Gold Ridge in the Solomon Islands.
Post-acquisition integration activities are well advanced and are progressing to schedule.
Tragically, on 8 September, a local villager working at the Simberi Mine was fatally injured in an incident involving the aerial rope ore transport conveyor. Mining operations were suspended and recommenced following a mourning period.
The following detailed report includes production and exploration results for the newly acquired assets for the full September quarter. It is important to note that gold production for the Pacific Operations is only attributable to St Barbara Limited from 7 September – a total of 23 days for the quarter.
With the exception of extended down time of the rope ore transport conveyor (see page 7), Simberi performance was consistent with expectations arising from St Barbara’s preacquisition on site due diligence.
Gold production at Simberi is anticipated to increase in the coming quarters, particularly with completion of the oxide processing expansion project, which is on track to be commissioned in the March 2013 quarter. New power generators due to be operational late in the December 2012 quarter will assist to reduce operating costs.
Gold Ridge performance did not, however, meet expectations due to poor mining performance and plant throughput seriously impacting gold production and unit costs. Intensive work is underway to lift the operating performance at Gold Ridge. St Barbara’s Technical Services team has been deployed to Gold Ridge, to work with the on-site team to improve mining efficiencies, materials handling and processing throughput and recoveries.
St Barbara’s June 2012 Quarterly Report foreshadowed that September 2012 quarter gold production from the Gwalia Mine in Western Australia was planned to be lower than the record June 2012 quarter.
On 1 September the Gwalia Mine completed a mining contractor transition from Barminco to Byrnecut Mining, and although the transition went smoothly in terms of people and logistics, poor haul truck reliability in September impacted mined tonnage from underground, and gold production. Mining of high grade underground ore was effectively deferred to the December 2012 quarter, gold production was lower than expected, and unit costs higher as a consequence. Byrnecut has responded well and haulage performance is now restored. Head grade and gold production are expected to lift markedly in the December 2012 quarter, and full year production and cost guidance for Gwalia is maintained.
The King of the Hills satellite mine, which provides ore to the Gwalia processing plant, exceeded expectations. Opportunities for expanding mineral resources on the Western Flank have been identified and will be tested by drilling in FY13.
At Southern Cross Operations in Western Australia, mining at Marvel Loch Underground will cease by the end of October 2012, with processing to be completed by the end of November when the plant is scheduled to go on to care and maintenance.
Overall, FY13 guidance for the Australian Operations is maintained, and we expect to update Allied Gold’s previous guidance for the Pacific Operations by 31 January 2013.

The mining of lower grade stopes from within the South West Branch (SWB) was in accordance with the mine schedule and gold production is expected to increase in the December 2012 quarter.
A change of underground mining contractor from Barminco to Byrnecut was completed smoothly with respect to people, logistics and safety performance at the end of August with Byrnecut in place and operating on 1 September 2012. Poor haul truck reliability did however impact mining performance in September resulting in lower underground ore tonnage and lower head grade than planned. Byrnecut responded by mobilising additional equipment to restore haulage performance to required levels. The shortfall in mill feed from underground was offset by processing low grade underground ore and surface stockpile material from Tower Hill, lowering processed grade to 6 g/t Au.
High grade underground production originally scheduled for September has been re-scheduled to the December 2012 quarter. Consequently, although gold production and unit cash operating costs did not meet expectations for the quarter, improved performance over the remainder of FY13 is expected and full year cash operating cost and production guidance is maintained.
The Gwalia mine produced 34,293 ounces of gold at a mined grade of 7.4 g/t Au and cash operating cost of $853 per ounce for the quarter.
Ore mined was sourced between 1,280 metres below surface (mbs) and 1,340 mbs, from the lower grade areas of the South West Branch and the South Gwalia Series lodes. South West Branch is expected to be the principal ore source for the foreseeable future.

Southern Cross Operations are currently winding down production from underground mining at Marvel Loch.
Despite the increase in cash operating cost, Southern Cross Operations generated positive cash flow for the quarter, as most of the development costs had been previously paid.
Outlook
During FY13, ore will be progressively sourced from the higher cost Western Flank. Forecast full year gold production is expected to be within the previous guidance range of 55,000 to 60,000 ounces.
Outlook
Underground mining operations at Marvel Loch are expected to cease by end-October 2012. Supplemented by low grade stockpiles, processing is expected to continue until the end of November 2012.

St Barbara assumed operational control of Gold Ridge on 7 September 2012.
Gold Ridge produced 14,079 ounces in the September quarter, down from 16,845 ounces in the June quarter, with production restricted by poor mining performance.
Total material movements were down 5% in the quarter at 1.23 million tonnes, while total ore production reduced 21% to 420,000 tonnes.
Process plant throughput reduced by 8% to 435,000 tonnes. Mill feed grade was 1.4 g/t Au in the quarter, which was slightly below expectations because of slow development of the new Kupers pit, which has delayed access to higher grade material. This in turn has led to increased reliance on sulphide material from Namachamata South and Valahaichichi pits, which has reduced gold recovery rates from 76% to 74%.
Gold Ridge performance has continued to suffer from poor mine planning and plan execution, and ore handling and plant performance. August and September rainfall at Gold Ridge was unseasonably heavy and impacted mining fleet performance. In the face of reduced total material movement, mining activity was concentrated on providing ore feed to the processing plant at the expense of waste stripping, and the operation effectively mined itself into a corner of limited ore availability. The situation was further compounded in late September when access to the new higher grade Kupers and Dawsons pits was lost when a culvert was washed away during a particularly heavy downpour. Scheduled ore feed from these areas was replaced by lower grade material that also contained higher levels of sulphides, which impacted plant recovery.
Low production rates combined with high fixed costs resulted in cash operating cost for the quarter of $1,713 per ounce.

Outlook
A significant body of work to address the mining and processing performance issues has commenced. New personnel with mining and processing expertise are being introduced at Gold Ridge to fill critical vacancies and boost capability. Mine plans are being completely recast with plan compliance and ore presentation as critical focus areas. Availability of additional mining equipment is being reviewed to claw back the shortfall in waste movement and build more flexibility into mine plans. Access to the Kupers and Dawsons pits will be re-established by the end of October 2012 with the installation of a new culvert. ROM ore blending and crusher feed will be closely supervised by a dedicated Superintendent to optimise ore handling

performance. Metallurgical characterisation work is providing new insights into the ore quality of the different deposits being mined, and will enable better blending and ore presentation.
Many opportunities to reduce operating expenditure have been identified and are being implemented.
Contract claims with GR Engineering Services (GRES) have now been settled and the St Barbara Technical Services Team is engaging with GRES to make the necessary improvements to the processing plant.
December 2012 quarter performance is expected to be an improvement on the September quarter with increasing gold production, and operating costs to be reduced by $1 million per month to around $7 million.
The Company expects to update Allied Gold’s previous FY13 guidance for the Pacific Operations, including Gold Ridge, by 31 January 2013. A strong performance trend is expected in the second half of FY13 as operational improvement initiatives gain traction.

St Barbara assumed operational control of Simberi on 7 September 2012.
Simberi produced 13,733 ounces in the September quarter, which was down 6% on the June quarter.
Simberi performance was significantly impacted by two extended one-off rope conveyor downtime events totalling 43 days. This was due to the failure of a splice in the conveyor belt, which took 25 days to repair in July and is a warranty issue with the equipment manufacturer. In addition, the entire Simberi operation was shut for three days following the fatality on site in early September, with the conveyor stopped for a subsequent 15 days to reestablish safe operations.
Conveyor stoppages resulted in material movements falling by 18% in the quarter to 717,000 tonnes. Ore feed was sourced from locations closer to the plant that contain higher levels of sulphides, and delivered by truck at significantly higher cost.
Ore mined was down 3% at 504,000 tonnes, with ore milled down 4% to 464,000 tonnes, impacted by the conveyor stoppages. Grade of ore milled and recovery rate were fairly consistent with the prior quarter at 1.1 g/t Au and 83% respectively.
Cash operating costs increased to $1,277 per ounce, affected by the lower production rates and high fixed cost profile of the operation.
Simberi Oxide Expansion
The expansion is being achieved through the installation of a new semi-autogenous grinding (SAG) mill, two new leach tanks, additional elution circuit and improved tailings treatment facilities.
All of the major components are now on site, with the exception of the apron feeder, which is clearing customs in PNG and due to arrive on Simberi within the next few days. The SAG mill is now installed with associated structural steel work close to completion. The additional leach tanks are in place and receiving final coating. The tanks are due for commissioning in November, along with the new gold

Leonora targets: The final 2 deep drill holes of a 12 hole program were completed south of Gwalia on the mine trend, totalling 929m, testing conceptual Gwalia-analogue targets. These drill holes intersected only low level anomalous gold values. However, based on geological information obtained from this drilling program, and detailed geological structural mapping underground at Gwalia and at the other mines in the district, a revised interpretation has been generated for the Leonora district, which will be used as the basis for future drill targeting.
During the quarter, a detailed structural geology study of King of the Hills was completed and a number of mineral resource extension targets identified, particularly in the Western Flank orebodies. Drill testing of these targets is planned for the remainder of FY13.
At the Sullivans Creek area, another conceptual target located 40km NNW of Gwalia Mine, 139 air-core geochemical holes, totalling 10,617m, were completed. Interpretation of the results from this program has generated 2 anomalous gold targets for drilling in the December 2012 quarter.
Other Areas
Power Supply Conversion
The conversion of the power plant at Simberi from diesel fuel to lower cost heavy fuel oil continued during the quarter. Four of the seven new Wartsila generators have now been installed and, following the later arrival of electrical and control cables, are expected to be operational late in the December 2012 quarter.
Yilgarn province, WA : The focus during the quarter was to generate new targets in the Pinjin, Mt Percy and Murphy’s Well tenements within the Yilgarn Province, WA. Geochemical air-core drilling is planned to commence in the December 2012 quarter on a number of prospects to generate new drill targets, including Yerilla and Lake Carnage, subject to negotiation of appropriate access arrangements and Government approval of work programs. Elsewhere in the Yilgarn province, project generation and acquisition activities will continue.

Gawler province, SA : A new tenement was granted near Whyalla (EL 4977), and access is being negotiated with the Department of Defence.
East Lachlan Fold Belt, NSW : The target in the Nyngan area of the East Lachlan Fold Belt, NSW, is intrusion-related porphyry copper-gold mineralisation within a large volcanic-intrusive complex situated under younger cover rocks on the western edge of the Great Artesian Basin. Results of a helicopter-borne electro-magnetic (EM) survey flown in the previous quarter were received from a test area, aimed at identifying areas of deep conductive rock alteration to assist the targeting process under cover rocks.
The Phase 2 drilling program totalling 2,617m was completed during the quarter. All drill holes intersected the targeted monzodiorite intrusions beneath the cover rock sequence from a depth of 130m. Although no significant gold-copper mineralisation was encountered in these widely spaced (up to 4km apart) drill holes, encouraging indications were observed as being proximal to potential mineralisation. Detailed mineralogical analysis is being conducted in parallel with interpretation of the EM survey, to further assist the vectoring process to possible mineralised systems.
South West Pacific
Simberi, Tatau & Tabar Islands, PNG
On Simberi Island, four holes totalling 779m tested structural targets in the Pigiput Bay Plantation area and one hole is in progress at Pigiput. Geochemical surface sampling continues with both reconnaissance ‘ridge and spur’, trenching and soil sampling within the area of mining lease ML136. Encouraging trench sampling results from Botlu South West (including 35m @ 6.1 g/t Au) and Sorowar East prospects are scheduled for follow-up by more trenching and the drilling in the December 2012 quarter. In exploration licence EL609, soil sampling commenced at Banesa on Big Tabar Island. The soil sampling will be used to support a detailed ground geophysical survey (IP), planned to start in the December 2012 quarter. The geophysics and soil sampling surveys are designed to test the extent of porphyry copper-gold mineralisation found in previous diamond drill holes.
Gold Ridge, Guadalcanal Island, Solomon Islands
Within the mining lease, 11 exploration holes, totalling 2016m, tested areas below and north of the Dawsons deposit. Better intercepts include (see Table 1):
- GDC032: 8m @ 2.3 g/t Au from 53m and 7m @ 3.2 g/t Au from 165m;
• GDC035: 4m @ 5.5 g/t Au from 3m and 23m @ 5.4 g/t Au from 33m and 8m @ 4.4 g/t Au from 144m,
test for new areas of mineralisation within the mining lease area.
Discovery and Growth Outlook
The December 2012 quarter will be largely focused on:
-
undertaking air-core geochemical drilling programs on several targets in the Yilgarn province subject to land access;
-
drilling near-mine targets in the Leonora area;
-
analysis of results from the East Lachlan Fold Belt, prior to a Phase 3 drilling program;
-
testing near-mine drill targets on Simberi Island;
-
generating new drill targets on Tatau and Tabar Islands based on detailed geochemistry and ground geophysics surveys;
-
drilling near-mine targets at Gold Ridge.
