Kimber Announces High Grade Gold-Silver Mineral Resource Estimate and
Improved Metallurgical Recoveries for Carmen Deposit

New Upgraded Geologic Model Supports Improved Recoveries - 96% for Gold & 72% for Silver for High Grade Mineral Resource

VANCOUVER, Nov. 18 /CNW/ - Kimber Resources Inc. (NYSE AMEX: KBX, TSX:KBR) is pleased to announce a new, upgraded mineral resource estimate for the Carmen Deposit at its 100% owned Monterde project, located in Mexico's Sierra Madre mining district. This estimate defines a high grade gold-silver mineral resource with improved metallurgical recoveries, which lies within an overall significantly larger, lower grade mineral resource. This new mineral resource estimate is based on 587 drill holes and 329 metallurgical tests completed to date, and has been created after a thorough geological and metallurgical review. The base case high grade mineral resource estimate is tabulated below, while additional details follow later in this release.

"We are extremely pleased with this new mineral resource estimate for the Carmen Deposit, which is underpinned by a very detailed geological model and technical work program, and which defines a significant tonnage of high grade gold-silver mineral resources with excellent metallurgical recoveries," said Gordon Cummings, President & CEO of Kimber. "Kimber is now in a position to commence the formal review of economics of the Carmen Deposit, based on this high grade gold-silver mineral resource, and we will review the optimal combination of open pit and underground operations, with a focus on profitability."

Metallurgical Recovery Highlights for High Grade Mineral Resource

Based on 329 individual metallurgical recovery characterization tests conducted across the entire Carmen deposit, trends have been identified that allowed recovery to be related to location within the deposit (along strike and to depth) and to grade, for each of silver and gold.

As a result of this extensive test work, at a cut off of 3 g/t recoverable gold equivalent, average modelled gold recoveries were 96% for indicated mineral resources and inferred mineral resources while the average modelled silver recovery was 72% for indicated mineral resources and 75% for inferred mineral resources.

Mineral Resource Estimation Process

The mineral resource estimate for the Carmen Deposit at Monterde was prepared by Mr. Gary Giroux P.Eng. a senior associate of Micon International and the results are effective at November 17, 2009. This mineral resource estimate was prepared using a three dimensional block model and ordinary kriging of 6 x 6 x 6 metre blocks while the inverse distance squared method was used for comparative purposes. The estimation of grades was constrained by models of the geological and mineralized zones created by Kimber geological staff under the supervision of Mr. Petrus (Marius) Mare, P.Geo. Mr. Petrus (Marius) Mare, P.Geo. is the Vice-President Exploration, and the designated Qualified Person ("QP") for the Monterde project under National Instrument 43-101. Models of the geology and mineralization of gold and silver at Carmen were reviewed and approved by Mr. Terrence Hennessey P.Geo. of Micon International. The wireframes of the high grade and low grade gold and silver mineralization were interpreted into various sub-domains to optimize the sample search orientation by Pierre Desautels P.Geo. of PEG Mining Consultants Inc. The gold and silver metallurgical recovery models used to calculate gold and silver recoveries by block and gold equivalent grade by block were prepared by Kimber staff and consultants, and reviewed and approved by Richard Gowans P.Eng., President of Micon International. Interpolated results are reported in indicated and inferred categories and were based on continuity of the mineralization and sample density.

This new mineral resource estimate for Carmen includes a high grade mineral resource considered to be potentially amenable to underground mining, and which is surrounded by a lower grade mineral resource halo, some of which may be amenable to open pit mining.

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 normally 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.

Details of High Grade Mineral Resource update for Carmen Deposit

Since the last block model mineral resource estimate for the Carmen deposit, reported in July 2006, Kimber has drilled an additional 18 core holes and 125 reverse circulation drill holes. In addition, 121 previously drilled, non-geotechnical core holes have been included in the drill hole database for mineral resource purposes. During 2008 and 2009, the principal objectives for the Carmen deposit have been the compilation of all of the geologic data to provide geological control for the resource estimates; and the modelling of the distribution of silver recoveries within the deposit. Gold recoveries do not vary much within the Carmen deposit. This new, upgraded mineral resource estimate is the result of this work.

The high grade mineral resource estimates at various cutoff grades are shown below, with the base case bolded:

Metallurgical Recoveries for Gold & Silver in Carmen Deposit

Micon International, under the supervision of Richard Gowans, P. Eng. Qualified Person, has approved the application of gold and silver metallurgical recovery models based on geographic and grade relationships defined in the recovery characterization tests noted above. These models take into account the improved geological understanding of the deposit derived from the review and reinterpretation of all available geological and drill data.

Gold recovery in the Carmen deposit is almost always good, based on recovery results from the characterization tests. The only visible factor influencing recovery appears to be that gold recovery increases with gold grade.

    
    A silver recovery model has been created with reference to:
    -   the grade of gold and silver in each sample;
    -   the physical location of the sample; and
    -   the mineralized structure where the sample was located.
    

Analysis of the silver recovery data led to the identification of 10 clusters identified as key based on the estimated number of recoverable ounces affected by a cluster.

In order to validate the gold and silver recovery models, and to facilitate refinements, 72 samples were selected in the summer of 2009 and tested for gold and silver recovery, in the same manner as the previously tested 257 recovery characterization samples. These samples were selected mainly from the 10 key clusters with varying depth, grade, location along strike and structural characteristics. The recovery model projected results in line with those obtained from the most recent laboratory results, supporting the validity of the model.

The gold and silver recovery models can be applied to any block model mineral resource estimate created in respect of the Carmen deposit.

Other Mineral Resource Estimates

The mineral resource estimates for Veta Minitas and Carotare, the other two gold-silver deposits that, with Carmen, comprise the Monterde Project, are expected to be released in the near future.

About Kimber

Kimber owns mineral concessions covering in excess of 39,000 hectares in the prospective Sierra Madre gold-silver belt, including the Company's 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 in order to evaluate the potential for a combined open pit and underground mining operation based on current mineral resources. The Company is now commencing a formal review of potential economics at the Carmen deposit. In addition, the Company has a 100% interest in the mineral concessions of its Pericones property, an 11,890 hectare property targeted for silver, located approximately 100 kilometres southwest of Mexico City.

QA/QC procedures incorporate blanks inserted at the core shack and standards inserted after sample preparation in respect of the Monterde Project samples. Pulps are analyzed by ALS Chemex at its laboratory in North Vancouver, British Columbia, using 50 gram sub-samples, using fire assay with an AA finish for gold and four-acid digestion and ICP finish for silver from a 0.4 gram subsample. High grade gold or silver intervals are re-assayed by fire assay with gravimetric finish.

Cautionary Note to U.S. Investors - The United States Securities and Exchange Commission permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. Kimber Resources uses certain terms on its website (and certain press releases), such as "measured," "indicated," and "inferred," "resources," which the SEC guidelines strictly prohibit U.S. registered companies from including in their filings with the SEC. U.S. Investors are urged to consider closely the disclosure in our Form 20-F which may be secured from us, or from the SEC's website at http://www.sec.gov/edgar.shtml.
