DECEMBER 2012 RESOURCE AND RESERVE STATEMENT
Evolution Mining Limited (ASX: EVN) is pleased to report that it has completed an update to its Mineral Resource and Ore Reserve estimates as at 31 December 2012.
Group Mineral Resources are now estimated at 7.7 million ounces gold equivalent, an increase of 10% compared to the June 2012 estimate of 7.0 million ounces. This change is after accounting for depletion by mining and is due to a significant increase at Pajingo (406koz) and increases at Edna May (101koz), Mt Rawdon (94koz) and Cracow (73koz).
Group Ore Reserves are now estimated at 3.6 million ounces gold equivalent, an increase of 7% compared to the June 2012 estimate of 3.3 million ounces. This change is after accounting for depletion by mining and is largely due to increases at Pajingo (145koz) and Mt Rawdon (112koz).
The most significant increase achieved in both Mineral Resources and Ore Reserves is the result of new drilling carried out in the 12 months to 31 December 2012. New geological interpretation and a rigorous reassessment of Evolution’s very large drilling database, particularly at Pajingo, also added significant ounces to both Mineral Resources and Ore Reserves. The commodity prices used for the resource and reserve update remain the same as those used for the previous estimate. Similarly, there have not been material changes to the cut-off grades used to estimate the Ore Reserves.
Resource definition drilling programs at all operations also resulted in a marked increase in Resource confidence with the amount of gold equivalent in the Measured category increasing 20%, Indicated increasing by 12% and Inferred consequently decreasing by 6%.
This resource and reserve update includes all exploration and resource definition drilling information up to 31 December 2012 and has been depleted for mining to 31 December 2012. Moving forward, the Group Mineral Resource and Ore Reserve statement will be updated annually only, with a 31 December cut-off date.
The Mineral Resources and Ore Reserves have been prepared according to the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (2004 JORC Code). Mineral Resources are reported inclusive of Ore Reserves.
Explanatory notes containing information on the parameters and methods used to estimate Mineral Resources and Ore Reserves are provided in the appendices to this announcement.

Appendix A
Discussion of Mineral Resources, Ore Reserves and Comparisons
Pajingo Mineral Resource
The December 2012 Pajingo Mineral Resource estimate of 6.97 million tonnes at 5.8g/t gold for 1,306koz represents an increase of 406koz (+45%) net of mining depletion compared to the June 2012 Mineral Resource.
Material changes in the December 2012 Mineral Resource estimate compared to the June 2012 estimate include:
-
An Increase of 145koz to the Jandam area (includes the Vera South lode, Faith, Leaping Dog and Olivia lodes that were reported individually for the site June 2012 Mineral Resources) as a result of drilling, new geological interpretation and Mineral Resource estimation methodology changes (refer below);
-
An increase of 135koz at Venue Underground as a result of drilling, new geological interpretation and Mineral Resource estimation methodology changes;
-
An increase of 90koz at Sonia and Sonia East as a result of drilling, new geological interpretation and Mineral Resource estimation methodology changes;
-
A combined increase of 34koz at Orchid, Veracity, Zed and Janine as a result of drilling, new geological interpretation and Mineral Resource estimation methodology changes; and
-
Mining depletion of 41koz.
Mineral Resource estimation methodology changes at Pajingo involved changes to the geological domaining, compositing and estimation search parameters.
Open-pit Mineral Resources are reported at a 0.5g/t gold cut-off, constrained by a A$1,350/oz pit optimisation shell and estimated using non-linear estimation methods into blocks with dimensions of 5 metres east by 2 metres north by 2.5 metres elevation.
Underground Mineral Resources are reported at a 2.5g/t gold cut-off, and largely estimated using Ordinary Kriging into parent blocks with dimensions 15 metres east by 5 metres north by 15 metres elevation and sub-blocks of 1.5 metres east by 0.5 metres north and 1.5 metres elevation.
Pajingo Ore Reserve
The December 2012 Pajingo Ore Reserve estimate of 1.62 million tonnes at 6.3g/t gold for 329koz represents an increase of 145koz (+79%) net of mining depletion compared to the June 2012 Ore Reserve.
The significant increase in the Ore Reserve is attributable to extensional and Resource definition drilling (primarily within the Zed and Sonia lodes), Mineral Resource estimation methodology changes, and re-evaluation of the remnant Mineral Resource areas and inclusion of these areas to the Ore Reserves (primarily at Jandam).
Material changes in the December 2012 Ore Reserve estimate compared to the June 2012 estimate include:
-
An increase of 77koz for Jandam as a result of re-evaluation of the remnant Mineral Resource areas and inclusion of these areas in the Ore Reserves;
-
An increase of 71koz for Zed as a result of extensional and resource definition drilling;
-
An Increase of 26koz for Sonia as a result of extensional and resource definition drilling; and
-
Mining depletion of 41koz.
Ore Reserves are reported above a cut-off grade of 3.0g/t gold (diluted panel grade) for underground and 0.65g/t gold cut-off for the open-pit. Ore Reserves were estimated based on a gold price of A$1,350/oz and a gold recovery of 96.0%.

Cracow Mineral Resource
The December 2012 Cracow Mineral Resource estimate of 4.29 million tonnes at 6.1g/t gold for 842koz represents an increase of 73koz (+10%) net of mining depletion compared to the June 2012 Mineral Resource.
Material changes in the December 2012 Mineral Resource estimate compared to the June 2012 estimate include:
-
Maiden reportable resources for the Coronation and Griffin structures of 93koz; and
-
Mining depletion of 55koz.
Mineral Resources are reported above a cut-off of 2.3g/t gold and estimated using Ordinary Kriging into blocks with a range of dimensions optimised to the characteristics and geometry of each deposit.
Cracow Ore Reserve
The December 2012 Cracow Ore Reserve estimate of 1.61 million tonnes at 5.3g/t gold for 273koz represents an increase of 31koz (+13%) net of mining depletion compared to the June 2012 Ore Reserve.
Material changes in the December 2012 Ore Reserve estimate compared to the June 2012 estimate include:
-
An increase of 39koz at Empire as a result of resource definition drilling;
-
An increase of 36koz at Roses Pride as a result of resource definition drilling;
-
An increase of 14koz at Klondyke North as a result of resource definition drilling;
-
Addition of 8koz at Griffin as a result of discovery and resource definition drilling; and
-
Mining depletion of 55koz (inclusive of mineralisation mined outside of the Ore Reserve).
Ore Reserves are reported above an average cut-off of 3.6g/t gold (varying slightly for different mining areas) and estimated based on a gold price of A$1,350/oz, a gold recovery of 93.0% and costs projected from historical performance.
Mt Rawdon Mineral Resource
The December 2012 Mt Rawdon Mineral Resource estimate of 56.7 million tonnes at 0.7g/t gold for 1,288koz represents an increase of 94koz (+8%) net of mining depletion compared to the June 2012 Mineral Resource.
Material changes in the December 2012 Mineral Resource estimate compared to the June 2012 estimate include:
-
An increase of 139koz due to model methodology changes (refer below);
-
Mining depletion of 58koz; and
-
An increase of 13koz from stockpile balances.
The June 2012 estimate was performed using Ordinary Kriging while the December 2012 estimate was performed using Multiple Indicator Kriging (MIK). Consequent enhancements to the Mineral Resource estimate includes improved internal waste domaining of the post-mineralisation intrusive to better constrain the mineralised zones.
The MIK method was reconciled with the July 2012 – December 2012 production showing an improved correlation between the December 2012 estimation and achieved mining performance. The variance was within approximately 1% on contained ounces compared to the reconciled mined figures.
Mineral Resources are reported above a cut-off of 0.23g/t gold and below the 31 December 2012 pit surface within a A$1,800/oz pit optimisation shell.

Mt Rawdon Ore Reserve
The December 2012 Mt Rawdon Ore Reserve estimate of 39.8 million tonnes at 0.8g/t gold for 1,026koz represents an increase of 112koz (+12%) net of mining depletion compared to the June 2012 Ore Reserve.
The Ore Reserve increase reflects an increase of the Indicated Mineral Resources for December 2012. The increase in Indicated Mineral Resources is due to an increase in gold estimated by the change in the modelling technique to MIK and resource definition drilling during 2012. Subsequent conversion of the Indicated Mineral Resources has resulted in an increase of the Ore Reserves.
The December 2012 Ore Reserve estimate has been reported above the cut-off of 0.3g/t gold using a A$1,350/oz gold price and gold recovery of 89.5%.
Edna May Mineral Resource
The December 2012 Edna May Mineral Resource estimate of 47.0 million tonnes at 1.1g/t gold for 1,643koz represents an increase of 101koz (+7%) net of mining depletion compared to June 2012 Mineral Resource.
The Edna May underground Mineral Resource remains unchanged since the June 2012 Mineral Resource as there has been no new geological data or interpretation.
Material changes in the December 2012 Mineral Resource estimate compared to the June 2012 estimate include:
-
An increase of 63koz in the Edna May open-pit due to resource definition drilling;
-
An increase of 23koz in the Greenfinch open-pit due to resource definition drilling;
-
Mining depletion of 54koz; and
-
A 14koz increase from a stockpile balance change.
The Mineral Resources are reported at a 0.4g/t gold cut-off for the Edna May and Greenfinch open-pits and a 3.0g/t gold cut-off for the Edna May underground.
The Edna May open-pit resource is reported above the 1050mRL (290 metres below the natural surface) and below the 31 December 2012 pit surface. The Edna May and Greenfinch open-pit resources were estimated using E-Type Multiple Indicator Kriging into blocks with dimensions 25 metres east by 25 metres north by 5 elevation and 20 metres east by 15 metres north by 5 elevation respectively.
The Edna May underground resource is reported below the 1050mRL and above the 800mRL and estimated using Ordinary Kriging into blocks with dimensions 5 metres east by 5 metres north by 5m elevation.
Edna May Ore Reserve
The December 2012 Edna May Ore Reserve estimate of 22.5 million tonnes at 1.0 g/t gold for 709koz represents a decrease of 59koz (-8%) net of mining depletion compared to June 2012 Ore Reserve.
The decrease in the December 2012 Ore Reserve estimate compared to the June 2012 estimate was due to mining depletion.
The Ore Reserve is reported above a cut-off of 0.4g/t gold and estimated using a gold price of A$1,500/oz and a gold recovery of 91.0%.
Mt Carlton Mineral Resource
The Mt Carlton Mineral Resource consists of the V2 and A39 deposits and stockpiled material from the A39 open-pit.
The December 2012 V2 Mineral Resource estimate of 25.2 million tonnes at 1.7g/t gold, 19g/t silver and 0.24% copper for 1,350koz gold, 15.1Moz silver and 59.7kt copper is unchanged from the June 2012 estimate. No

==> picture [478 x 137] intentionally omitted <==
additional resource definition drilling or Mineral Resource estimates have been conducted since the June 2012 estimate.
The December 2012 A39 Mineral Resource estimate of 2.95 million tonnes at 170g/t silver and 0.12% copper for 16,134koz silver and 3.4kt of copper represents an increase of 647koz silver compared to the June 2012 estimate. The change is a result of grade-control drilling having identified additional mineralisation in the A39 open-pit. This material has been mined and trucked to the Run of Mine (“ROM”) stockpile and is recorded as stockpile material in the Mineral Resource statement. No additional resource definition drilling or Mineral Resource estimates have been conducted since the June 2012 estimate.
The V2 Mineral Resource is reported above a cut-off of 0.35 g/t Au and estimated using E-Type Multiple Indicator Kriging into blocks with dimensions 25 metres east by 25 metres north by 5 metres elevation.
The A39 Mineral Resource is reported above a cut-off of 42g/t silver and estimated using a combination of Ordinary Kriging for more broadly spaced resource definition drilling and Sequential Gaussian Simulation for close spaced grade-control drilled areas, into blocks with dimensions 10 metres east by 10 metres north by 2.5 metres elevation. The A39 Mineral Resource is reported below the 31 December 2012 pit surface.
Mt Carlton Ore Reserves
The December 2012 Mt Carlton Ore Reserve estimate of 10.4 million tonnes at 3.7g/t gold equivalent for 1.23 million gold equivalent ounces represents a small increase compared to the June 2012 estimate as a result of grade-control drilling having identified additional mineralisation in the A39 open-pit (see discussion under Mt Carlton Mineral Resources above).
The V2 deposit Ore Reserve is reported at a 0.69 g/t gold cut-off and used metal recoveries proportionate to head grade with gold recovery ranging from 82.0% to 90.0% and silver and copper recoveries ranging from 84.0% to 90.0%. The A39 deposit Ore Reserve is reported at a 53g/t silver cut-off and used 88.0% and 92.0% for silver and copper recoveries respectively. Mt Carlton Ore Reserves are estimated using metal prices of A$1,350/oz for gold, A$28.00/oz for silver and A$2.00/lb for copper.
Twin Hills Mineral Resource
The December 2012 Twin Hills Mineral Resource estimate of 4.62 million tonnes at 2.7g/t gold for 399koz remains unchanged from the June 2012 estimate. There are no changes to the Mineral Resource as no new drilling or estimation has been conducted at Twin Hills during the period.
The Mineral Resource estimate for the Twin Hills open-pit deposit is reported above a cut-off of 0.5g/t gold and within a A$1,500/oz pit shell. The Mineral Resource estimates for the Twin Hills Underground Deposits are reported above a cut-off of 2.0g/t gold.

Notes:
Data is reported to significant figures and differences may occur due to rounding Mineral Resources are inclusive of Ore Reserves
Mt Carlton V2 deposit Mineral Resources have been reported above a cut-off grade of 0.35 g/t gold and A39 deposit reported above 42g/t silver
Mt Carlton V2 deposit was estimated using E-Type Multiple Indicator Kriging into blocks with dimensions 25 metres east by 25 metres north by 5 metres elevation
Mt Carlton A39 deposit was estimated using a combination of Ordinary Kriging, for more broadly spaced Resource Definition drilling, and Sequential Gaussian Simulation for close spaced grade control drilled areas of the deposit into blocks with dimensions 10 metres by 10 metres by 2.5 metres elevation
Competent Person: John Winterbottom a member of Australian Institute of Geoscientists
The gold equivalence calculation represents total metal value for each metal summed and expressed in equivalent gold grade and ounces. The prices used in the calculation being A$1350/oz Au, A$28.00/oz Ag and A$2.00/lb Cu. Metallurgical recovery to concentrate of 90.0% for gold, 92.0% for silver at V2 and 88.0% silver at A39 and 92.0% for copper as indicated by metallurgical testwork
1 Troy Ounce = 31.1034768 grams Au Eq for Silver = ((Price Ag per Oz x Ag Recovery)/(Price Au per Oz x Au Recovery)) x Ag Grade Au Eq for Copper = ((Price Cu per lb x 2204.623) x (Cu Recovery)) / (Price Au per Oz x Au Recovery / 31.1034768) x (Cu Grade / 100)

Notes:
Data is reported to significant figures and differences may occur due to rounding V2 Ore Reserves are reported above a 0.69 g/t gold cut-off and A39 Ore Reserves reported above a 53 g/t silver cut-off Ore Reserves were calculated using a gold price of A$1,350/oz, silver price of A$28.00/oz silver price and copper price of A$2.00/lb V2 deposit used variable recoveries proportionate to head grade with gold recovery ranging from 82.0% to 90.0%, silver and copper recoveries ranged from 84.0% to 92.0%
A39 deposit used 88.0% and 92.0% for silver and copper recoveries respectively Smelter payabilities were also considered in the reserve calculation Competent Person: Tony Wallace a member of the Australasian Institute of Mining and Metallurgy The gold equivalence calculation represents total metal value for each metal summed and expressed in equivalent gold grade and ounces. The prices used in the calculation being A$1350/oz Au, A$28.00/oz Ag and A$2.00/lb Cu. Metallurgical recovery to concentrate of 90.0% for gold, 92.0% for silver at V2 and 88.0% silver at A39 and 92.0% for copper as indicated by metallurgical testwork Au Eq for Silver = ((Price Ag per Oz x Ag Recovery)/(Price Au per Oz x Au Recovery)) x Ag Grade
Au Eq for Copper = ((Price Cu per lb x 2204.623) x (Cu Recovery)) / (Price Au per Oz x Au Recovery / 31.1034768) x (Cu Grade / 100)
