Quarterly Report
For the period ending 31 March 2012
Highlights
-
Group gold production of 84,122oz at an average cash cost of A$809/oz in the March quarter. Group production and costs remain in line with FY2012 guidance of 335 – 375koz (265 – 300Koz attributable[1] ) at an average cash cost of A$800 – A$850/oz
-
Benefits of operational diversity evident – lower production at Edna May offset by strong quarter at Mt Rawdon; access to higher grade ore at Mt Rawdon underpinned record monthly production in March with improved performance planned to continue in June quarter
-
Solid operational cash flow resulted in increased cash at bank of A$171M, after investment of some A$70M in capital during the quarter
-
Construction of Mt Carlton gold-silver-copper project in Queensland now one third complete and commissioning on schedule for December quarter 2012; project capital cost estimate revised to A$145M from A$127M following changes to project scope and increased construction costs
-
Further exploration drilling at Cracow confirms new high-grade epithermal gold shoot 250m from current mining operations; initial Inferred Mineral Resource estimate for new shoot, named Coronation, is targeted in FY2013
-
Underground Mineral Resource estimate for Edna May increased by 70% to 270,000oz; Resource defined to a depth of 550 metres and remains open at depth and along strike
-
Inclusion in the S&P/ASX 200 Index from 17 March 2012 in recognition of increased scale and liquidity

Cracow, Queensland (100%)
Cracow’s March quarter production was 24,119oz of gold at a cash cost of A$707/oz. This compares with the December quarter production of 25,724oz (20,492oz attributable) of gold at a cash cost of A$637 (attributable).
Gold production was in line with expectations and ore was sourced from five orebodies during the quarter; Kilkenny, Phoenix, Sovereign, Klondyke North and Roses Pride.
A number of initiatives commenced to improve mine productivity levels including the design and development of a medium term ventilation project to double the primary ventilation flow in the lower areas of the mine. Poor ventilation temporarily suspended development of the Kilkenny decline with development scheduled to recommence in the June quarter following the completion of the ventilation upgrade.
A total of 125,275t were treated at an average grade of 6.37g/t Au. The mill achieved excellent availability (96.7%) and recovery (94%) for the quarter. Construction of a 4m tails dam lift was completed on time and under budget, providing approximately 13 months of tails storage capacity when required for use. Production in the June quarter is forecast to be similar to the March quarter.
1 Includes increased interest in Cracow from 30% to 100% on 2 November 2011, 100% of Mt Rawdon from 2 November 2011, and 100% of Pajingo from 18 October 2011, and corrected silver production from the December 2011 quarterly report 2 Before royalties and after silver credits
3 Includes cash costs, depreciation, amortisation, royalties and exploration
4 Re-stated cash cost following site-wide implementation of standardised accounting policies in line with current Australian industry practice resulting in a material impact on Edna May’s reported cash operating costs

Pajingo, Queensland (100%)
As anticipated, Pajingo’s March quarter production was lower than the December quarter with production of 17,588oz of gold at a cash cost of A$832/oz (December quarter 26,068oz (21,229oz attributable) at a cash cost of A$535/oz (attributable).
Although a decrease on the previous quarter’s production, gold production was in line with expectations as a result of modifications to the open pit mining schedule following delays to Venue/VNU open pit and a deliberate change in the underground mining plan to undertake capital works for the ventilation system to enable ongoing mining production of the Zed East, Sonia and Faith orebodies.
Ore production from underground totalled 65,451t at 10.15g/t Au from Jandam, Bell Vein, Zed West, Faith and Sonia orebodies with total development of 1,154m during the quarter. This development excludes 455m of vertical development for the ventilation system which impacted on haulage capacity and hence restricted the horizontal capital development capabilities. These capital works complete the excavation component of the long term vertical requirement for the ventilation system.
Open pit ore production in the quarter was 25,905t at a grade of 1.2g/t Au sourced from cutback activities in the Janet A open pit. The pit floor will be accessible for mining in April and the pit will be completed by mid-May. Approximately 8,000oz remain in the Janet A open pit at the end of the quarter. It is anticipated that mining of the Venue/VNU open pit will commence at the beginning of FY2013.
A total of 110,533t at 5.1g/t Au were treated during the quarter, a decrease on the previous quarter’s performance (Dec 2011: 132,505t at 6.57g/t Au). Some delays were encountered during the quarter due to wet weather and the inability to crush wet ore, however, these delays were made up and minimal ore was in stockpile at the end of the quarter. Production in the June quarter is forecast to exceed this quarter’s gold production with production for FY2012 now planned to approach 80,000oz – a 174% increase on FY2011 production of 45,889oz.
Edna May, Western Australia (100%)
Edna May’s March quarter production was 16,312oz of gold at a cash cost of A$988/oz. This compares with the December quarter production of 20,006oz (100% attributable) of gold at a cash cost of A$814.
Total material movement of 2,001,366t comprising 722,572t of ore at 1.07g/t Au and 1,278,794t of waste was completed (Dec 2011 qtr: 2,189,625t total; 616,999t at 1.12g/t Au ore; 1,572,626t waste). Ore was predominantly sourced from the B-Cut pit which is now essentially 100% ore, whilst waste was sourced from the C-Cut which is advancing to the next ore supply.
A total of 541,030t were treated at an average grade of 1.05 g/t Au (Dec 2011 qtr: 623,357t at 1.11g/t Au). Gold production was below expectation due to six days of unplanned downtime to repair damage to the ball mill girth gear and pinion resulting from slurry ingress. Lower than anticipated gold production drove unit costs higher than planned.
A ten day shutdown is planned for the June quarter to rotate the ball mill girth gear and install a refurbished pinion as is a four day planned shutdown for mill relining work. Production in the June quarter is forecast to be marginally higher than this quarter. Improvements to plant reliability remain the focus with technical specialists engaged to lift performance with primary areas of focus including:
-
Maintenance systems;
-
Operational philosophy and controls;
-
Procurement and supply;
-
Lubrication system upgrade;
-
Primary crusher works; and
-
Critical spares.

Mine-to-Mill strategies for improving fragmentation are also in progress including optimisation of drill and blast and load and haul. Two rock breakers were employed full time on the ROM to reduce the level of oversized ore stockpiled with another employed predominantly within the pit to reduce oversized ore before it is transported to the ROM.
Construction of the process water bore field and pipeline 15km west of Edna May, to improve water security, is on schedule for completion in the June quarter.
Mt Rawdon, Queensland (100%)
Mt Rawdon’s March quarter production was 26,104oz of gold at a cash cost of A$776/oz. This compares with the December quarter production of 18,014oz (12,367oz attributable) of gold at a cash cost of A$893/oz (attributable) and includes a record monthly production of 11,865oz in March.
Gold production was in line with expectations as mining of the Stage 2 cutback accessed central, higher grade ore sources.
Total material movement of 4,246,088t comprising 1,016,149t of ore at 0.88g/t and 3,229,889 tonnes of waste was completed. (Dec 2011 qtr: 4,430,472t total, 1,193,670t at 0.75g/t ore, 3,236,802t waste). Total material mined was down slightly on the December quarter due to above average rainfall between January and March. Mining of the Stage 3 cutback commenced with ore to be accessed during the second half of FY2013.
A total of 895,474t were treated at 1.00g/t, an increase on the December quarter (Dec 2011 qtr: 811,671t at 0.76g/t Au) with mill throughput improving to average 9,840tpd for the quarter (Dec 2011 qtr: 8,812tpd). Feed grade is forecast to average higher than 1.00g/t for the remainder of FY2012. A major four day maintenance shutdown is planned in April to facilitate the installation of increased gravity recovery capacity and to undertake scheduled mill relines.
Production in the June quarter is forecast to increase as mining accesses the higher grade central zone of the orebody.

DEVELOPMENT
Mt Carlton, Queensland (100%)
Construction of the Mt Carlton gold-silver-copper project advanced significantly during the quarter. Construction is now over one third complete and is on schedule for commissioning in the December quarter 2012.
The Mt Carlton project is estimated to produce 800,000oz of gold, 17.3Moz of silver and 34,000t of copper over a current mine life of 12 years.
Expenditure from the commencement of the construction period to the end of the March quarter totalled A$41M. As engineering design and drafting is nearing completion, an updated project forecast has been undertaken. The project cost is forecast to be A$145M (previously estimated to be A$127M). The increase of A$17M is due to scope changes to reduce operational risk and allow for throughput capacity options; increased approval and compliance costs for environmental conditions; and increased construction costs.
During the quarter the focus of project development activities has been:
-
Engineering design and drafting; near completion;
-
Site civil works for the process plant, site infrastructure and access road;
-
Concrete work in the process plant; SAG mill area concrete 80% complete;
-
Construction and commissioning of the first phase of the permanent camp;
-
Commencement of stripping of topsoil for the A39 open pit;
-
Commencement of construction of the Tails Storage Facility and main water dam; and
-
Recruitment of the operational workforce
EXPLORATION
Cracow, Queensland
Resource Definition
Resource definition drilling to support an upgrade of the Kilkenny and Tipperary Mineral Resources at Cracow was undertaken during the quarter. Underground resource definition drilling continued at the Kilkenny Shoot with 4 holes for 1,252m being completed. The results to date at Kilkenny are in line with expectations, and drilling remains on track to achieve the conversion of the Inferred Resource to an Indicated category. At Tipperary, 14 holes were drilled for a total of 944.9m targeting northern extents of the shoot with a best intercept of 7.0m grading 9.16g/t Au from 115.0m.
Mine Lease Exploration
Recent diamond drilling along the Kilkenny structural trend, some 150m north of known mineralisation, has confirmed the presence of a new high-grade epithermal gold shoot. The shoot has been named Coronation.
Exploration drilling along the Kilkenny structural trend initially intersected high-grade mineralisation in December 2011 when drill hole CBK317R intersected 35.90m (8.68m[5] ) grading 6.76g/t Au from 625m (as reported in the December 2011 Quarterly Report[6] ). Ongoing drilling has subsequently confirmed the continuity of the mineralisation. Recent best intercepts from Coronation included:
- 25.40m (4.13m[5] ) grading 6.47g/t Au from 611.6m in CBK316
5 Estimated true width 6 Revised estimated true width. Original estimate was 11.02m @ 6.76g/t Au as reported in December 2011 Quarterly Report
==> picture [416 x 120] intentionally omitted <==
-
13.70m (3.61m[5] ) grading 8.01g/t Au from 539.0m in CBK317W3
-
2.80m (0.83m[5] ) grading 61.53g/t Au from 505.2m including 1.00m (0.30m[5] ) grading 125.00g/t Au in CBK318
The Coronation shoot is located approximately 550m below surface and 250m north of active mining operations (Figure 1). It remains open both up and down plunge and along strike. Infill drilling to date has demonstrated continuity of mineralisation, with ongoing drilling aimed at testing extensions to mineralisation and targeting an Inferred Mineral Resource estimate in FY2013.

Regional Exploration
Greenfields reconnaissance exploration continues to identify a number of new structures exhibiting prospective epithermal quartz vein textures.
At Golden Mile South, assay results of up to 17.30g/t Au and 375.00g/t Ag were received from selective rockchip sampling along a 500m trend containing two parallel intermittently outcropping 0.1m to >1m wide epithermal quartz veins. At least 400m of this structure has not been drill tested and remains a focus for ongoing exploration.

Pajingo, Queensland
Resource Definition
A series of short extensional and resource definition drill programs totalling 48 holes for 9,938m were completed underground during the quarter at Zed West, Faith, Sonia, and Sonia East. Best intercepts were returned from Sonia (7.0m grading 5.38g/t Au) and the Sonia East vein including:
-
5.64m grading 8.48g/t Au from 108m in 0767_37_BN
-
2.45m grading 66.62g/t Au from 124m in 0767_38_BN
-
2.15m grading 28.13g/t Au from 108m in 0767_37_BN
-
6.46m grading 8.61g/t Au from 108m in 0767_37_BN
Note: intersections are not true width with some being acute to the interpreted orebody
The Sub-Guinness program, targeting new mineralised systems parallel to the main Vera Nancy structure commenced during the quarter. At Powerline, drilling targeted a north east trending structure parallel to Veracity with results indicating that mineralisation improves towards surface and further drilling is being considered with respect to a possible open pit target.
Regional Exploration
Regional exploration during the quarter remained focused on drilling at the Moonlight prospect and along the Starlight corridor (Starlight B) where a total of 20 holes (RC and diamond) for 6,732m were completed.
At the Moonlight prospect, drilling targeted a northwest trending zone of mineralised epithermal quartz veining and brecciation approximately 1.5km south of mine infrastructure where mineralisation has to date been intersected over a strike length of approximately 300m. The zone of mineralisation remains open along strike to the northwest and southeast (Figure 2). Best intercepts returned during the quarter included:
-
19.35m grading 4.71g/t Au from 455.3m including 7.2m grading 9.03g/t Au in JMRD3682
-
7.30m grading 5.67g/t Au from 465m including 0.5m grading 12.20g/t Au and 1.7m grading 14.56g/t Au in JMRD3702A
-
14.00m grading 3.22g/t Au from 472m including 3m grading 6.43g/t Au and 1m grading 11.70g/t Au in JMRD3703
-
2.30m grading 5.26g/t Au from 468.6m including 1m grading 7.69g/t in JMRD3741
-
2.10m grading 3.63g/t Au from 478.0m including 0.3m grading 17.80g/t Au in JMRD3741
Drilling at Starlight B testing a geophysical anomaly was successful in intersecting gold mineralisation with a best intersection of 6.0m grading 2.32g/t Au from 6m in JMRD3744. Further drilling is in progress.

Edna May, Western Australia
Resource Definition
A revision of the Edna May Underground Mineral Resource was completed during the quarter and resulted in a 70% increase to 1.2Mt at 7.0g/t gold for 270,000oz of which 50% is classified as Indicated Mineral Resource (ASX release 27 February 2012). The upgrade in Mineral Resource confidence was enabled through recent infill and extensional diamond drilling completed during 2011 for a total of 19 diamond holes for 10,303m.
Drilling programs targeted the infill of high value areas of the Resource and extensional targeting aimed at testing depth and strike extensions to mineralisation. To date, this has resulted in the definition of additional reefs in the hanging wall of the Edna May Gneiss and successfully defined strong grade continuity both laterally and at depth.
The February 2012 Edna May Underground Mineral Resource was estimated using Micromine Ordinary Kriging block modelling techniques, and reported on a 3g/t Au cut-off grade within geologically and grade defined mineralisation envelopes in accordance with the Australian JORC Code.
Two geological domains were defined for grade estimation: high-grade quartz reef mineralisation and corresponding halo mineralisation. A total of eight mineralised reefs were interpreted corresponding to down dip extensions of historically mined reefs together with newly identified hanging wall reefs to the Edna May Gneiss.

==> picture [416 x 120] intentionally omitted <==
The underground Mineral Resource has only been defined to a depth of 550m below surface and remains open both at depth and along strike. Infill drilling to date has prioritised the upgrade of Inferred Resources close to the existing decline, beneath the open pit operation.
The previous Mineral Resource estimate for the Edna May Underground was reported above a 3g/t cut-off in May 2011 and comprised a total of 700,000t at 7.4g/t Au for 166,000oz and was classified as Indicated and Inferred.

Mine Lease Exploration
The Greenfinch diamond drilling program targeting down dip extensions to high-grade gold mineralisation commenced this quarter with nine holes for 3,762m drilled. Strike and dip extensions of the Greenfinch gneiss were significantly extended and displayed moderate to intense amphibole alteration. A follow-up resource definition RC drilling program will commence from next quarter consisting of 28 drill holes totalling 5,800m.
Mt Rawdon, Queensland
Regional Exploration
Results were received from the drillhole at Mt Shamrock designed to test the down-plunge potential of the Kent’s Knob intrusive mineralised zone. Gold mineralisation was intersected in altered sediments indicating that lithology may control the distribution of mineralization with a best intersection of 10.0m grading 0.82g/t Au from 269.9m in MSRD005.
Five RC drillholes were completed for 1,304m targeting the Arabanga Volcanic Stratigraphy immediately south of the Mt Rawdon mine. While some results are still pending, results from three holes returned low level anomalism.
Mt Carlton, Queensland
Mine Lease Exploration
Exploration drilling recommenced at Mt Carlton in late March after a two week delay caused by seasonal rain. Drilling recommenced in late March to test mine targets to the north east of V2 deposit and north of A39 deposit where previous shallow drilling identified a broad zone of gold-silver-copper mineralisation coincident with the north east extension of a distinct IP chargeability corridor, similar to the geophysical expression of the V2 East zone. Currently ten drill holes are planned to test this zone.
Regional Exploration
Mt Carlton regional exploration during 2012 and 2013 is planned to focus on the Capsize trend, a 15km east-west zone of intense alteration extending east of V2 pit which includes known prospects at Capsize Creek and Strathmore at the western extent. Systematic sampling is planned over a number of targets defined by historical rock chip sampling and structural/magnetic zones.
Better intersections returned during the March 2012 quarter from all projects are presented in Table 1.

Pajingo Pastoral Leases
During the quarter Evolution acquired the Britannia and Doongara pastoral leases that overlie the line of lode and major infrastructure at the Pajingo mine. Ownership of the pastoral leases provides long term security of access to mine infrastructure and potential future discoveries. The properties are sub-leased to a pastoralist with whom Pajingo has had a good working relationship and we look forward to continuing this relationship.
