VANCOUVER, June 8, 2011 Reduced open pit size and strip ratio, increase in measured mineral resource for Carmen DepositAfter tax IRR of 40.6% and 2 year payback at $1100 gold and $19 silver
VANCOUVER, June 8, 2011 /PRNewswire/ – Kimber Resources Inc. (NYSE AMEX:KBX, TSX:KBR) is pleased to announce that it has received the results of an updated independent Preliminary Assessment (“PA”) prepared by Micon International Limited. (“Micon”), with assistance by Kirkham Geosystems Ltd., Knight Piésold Consulting Ltd. and various consultants employed directly by Kimber on its 100% owned Monterde project, located in Mexico’s Sierra Madre mining district. This National Instrument 43-101 compliant PA is based on the updated mineral resource estimate for the Carmen deposit and the existing mineral resource estimate for the Veta Minitas deposit at Monterde prepared by Micon. The PA is based on combined open pit and underground mining and a focus on the high grade gold-silver mineralization and demonstrates significantly improved financial outcomes compared to the initial PA, a summary of which was discussed in a news release issued by Kimber on June 2, 2010.
“We continue to make progress in reducing project development risk and improving projected financial returns at Monterde,” said Gordon Cummings, President & CEO of Kimber. “In the updated PA, the open pit strip ratio has been reduced by more than 50%, the open pit is smaller, and in-pit measured mineral resources now comprise 30% of open pit tonnage, with measured and indicated (“M&I) mineral resources making up 80% of open pit tonnage, and having significantly higher gold and silver grades than the inferred mineral resources. These improvements have reduced both the open pit cash costs per tonne and project capital expenditures, leading to a faster payback and higher internal rate of return (“IRR”), even when using the 2010 PA gold and silver price estimates. The higher metals prices used in the updated PA (being US$1100/oz gold and US$19/oz silver) demonstrate the degree of leverage that Monterde has to rising gold and silver prices. Moreover, the revised PA does not incorporate any results from our 2011 drilling program, which have the potential to further increase gold and silver mineral resources and enhance project economics.”
Highlights of the Updated Preliminary Assessment for Monterde
- Before tax (at prices of US$1100 per ounce of gold and US$19 per ounce of silver):
- IRR of 47.9% with undiscounted net cash flows of US$585 million;
- Project net present value (“NPV”) (at an 8% discount rate) of US$295 million.
- After tax (at prices of US$1100 per ounce of gold and US$19 per ounce of silver):
- IRR of 40.6% with undiscounted net cash flows of US$430 million;
- Project NPV (at an 8% discount rate) of US$211.9 million;
- Payback of pre-production capital and operating costs within 2 years.
- After tax (at near spot prices of US$1500 per ounce of gold and US$35 per ounce of silver):
- IRR of 71.9% with undiscounted net cash flows of US$876.9 million;
- Project NPV (at an 8% discount rate) of US$471.8 million;
- Payback of pre-production capital and operating costs after 1 year
- Pre-production capital of US$100.1 million, with total life-of-mine capital cost of US$119.3 million, including a total contingency amount of US$28.3 million.
- Total mine life of 15.5 years, with combination of open pit and underground production for 9.3 years at an average mill throughput of approximately 2,800 tonnes per day, followed by underground only for 6.2 years, with average mill throughput of approximately 1,000 tonnes per day.
- Average annual production of 58,400 ounces of gold and 1.9 million ounces of silver for the first 9 years of production.
- Life-of-mine cash costs of US$151 per ounce of gold, with silver as a by-product credit, and total costs of production, including capital costs, of US$311 per ounce of gold, with silver as a by-product credit.
- Average annual production of 90,400 gold equivalent ounces for the first 9 years of production
- Total production of 744,000 gold ounces and 20.2 million ounces of silver over the total mine life of 15.5 years
- Life-of-mine cash costs of US$450 per gold equivalent ounce and total costs of production for life-of-mine, including capital costs, of US$538 per gold equivalent ounce.
The mine plan in the updated PA involves a combination of open pit and underground mining, with material processed in a mill in order to maximize recoveries. Further information regarding key mine plan parameters and assumptions used in this Preliminary Assessment as well as information relating to mineral resources for the Carmen deposit is included in an appendix to this news release.
Economic Analysis
The economic assessment in the PA is preliminary in nature and uses inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that this preliminary economic assessment will be realized. The inferred mineral resource used in the mine plan represents 32% of the total life-of-mine (“LOM”) mineral resource.

Gold equivalent ounces referred to in the updated PA are based on prices of US$1100/oz gold and US$19/oz silver for recovered ounces, giving a ratio of 57.9 to convert recoverable silver ounces to gold equivalent ounces. After refining charges, net revenue per payable ounce has a ratio of 58.7 to 1. Gold equivalent ounces referred to in the mineral resource estimate tables are based on a ratio of gold to silver of 58.3 to 1.
Mineral resources within the updated PA proposed pit of the Carmen Deposit
As a result of re-estimating the mineral resources within the updated open pit, a portion of the total was classified in the measured category, as shown in the tables below:

The mineral resources used in this updated PA were estimated by Gary Giroux P.Eng., Senior Associate of Micon, in April 2011 based on drill data up to October 2009 and the only difference to the October 2009 database used for the Carmen mineral resource estimate of November 2009 is the addition of 49 surface trench assays from November 2010 that were added to increase the available grade information near surface. This updated mineral resource estimate used for this updated PA resulted in no material changes to total mineral resources for gold and silver in the measured plus indicated or inferred categories. More complete details of the mineral resource estimates used in this updated PA are shown in the appendix to this news release.
Compliance with National Instrument 43-101
Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution. These mineral resource estimates include inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to the measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied.

About Kimber
Kimber owns mineral concessions covering in excess of 39,000 hectares in the prospective Sierra Madre gold-silver belt, including the Monterde property, where three gold-silver mineral resources have already been defined. The most advanced of these, the Carmen deposit, has been extensively drilled and has undergone detailed geologic modeling. The completion of the Preliminary Assessment for Monterde in 2010 represented a significant step forward for Kimber and is expected to lead to further development and more advanced economic studies at the Monterde deposits including the completion of a pre-feasibility study during 2011.
