VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 26, 2013) - Kimber Resources Inc. (News - Market indicators)(NYSE MKT:KBX) today announced results from its underground rehabilitation and sampling program within the historic Carmen Level 1, underground workings of the Carmen deposit at the 100% owned Monterde gold-silver project in Chihuahua, Mexico. Level 1 is the middle and most extensive of three levels developed on the Carmen deposit. Assay results from Level 1 at Carmen show significant strike lengths of high grade gold and silver mineralization remaining on the vein structure that were not removed by mining in the 1930's and 1940's. The continuity of these high grade zones, over significant strike lengths, supports the potential for similar continuity of high grade zones intersected in other areas of the Carmen deposit.

Individual sample highlights from the sampling program are as follows:

"We continue to be encouraged by the results of our underground sampling program in the Carmen deposit," said Gordon Cummings, President and CEO of Kimber Resources. "The historic mining targeted areas of high grade gold and silver mineralization with good continuity. This underground sampling program returned grades as high as 7.87 g/t gold equivalent over 25 metres of strike length. These results, showing continuity of high grade gold and silver, further adds to our belief that the Carmen deposit offers excellent economic potential." 

The sampling results at Carmen, combined with drill results, have successfully provided valuable information, including: 

1. Support of continuity of the zones of high grade mineralization within the Carmen vein structure in the old mine workings.
2. Distribution of gold and silver within the mineralized zones on the Carmen structure.
3. Mineralization controls, including lithological and structural.
4. Ground conditions for mine development planning and economics.

The following highlights some of the notable mineralization interpreted following compilation of the results from Carmen Level 1 (see figures 3-4 for further illustration):

See Figures 1-4 for detailed images showing sample results. The sampled areas were between the mined out sections of the vein (stopes) from the historic work in the 1940's which, in all probability, had better grades and/or thicknesses as they were mined out, whereas the material sampled by Kimber was left behind.

Description of style of mineralization and geology

In addition to confirming the favourable nature of the gold and silver mineralization along the Carmen vein structure, sampling of several cross cut drifts driven into the hanging wall and footwall of the principle vein correlate well with the modeling of the disseminated mineralization in the adjacent wall rock that surrounds the higher grade zones. Comparison of the cross cut samples with nearby reverse circulation and core drill holes provided further support of the geological model at Carmen. For example, sample results from the hanging wall mineralization exposed in the first cross cut drift over 26 metres of sample width averaged at 0.28 g/t gold, 61.9 g/t silver for 1.46 g/t gold eq. adjacent to the Carmen vein. 

Of special interest was the observation that the more permeable TBX and FTU lithological units allowed dissemination of the mineralizing fluids into the rock adjacent to the Carmen and Hilos vein structures. The more massive and brittle PQ unit was favorable for formation of vein stockworks and breccias. The TBX unit is a volcaniclastic unit consisting of mudflow (lahar) deposits deposited in paleo-river channels eroded in the underlying volcanic tuff deposits. Rounded boulders and cobbles of altered volcanics are surrounded by volcanic ash and sandstone that are permeable to the hydrothermal fluids, allowing the mineralization to spread laterally out from the vein structures. Similarly, the FTU unit, a weakly to moderately consolidated volcanic breccia deposit found beneath the TBX, has good permeability allowing for the mineralization to disseminate into the surrounding country rock. The PQ unit is interbedded with the TBX and FTU units, and consists of thick, massive lava flows of rhyolite to rhyodacite quartz porphyry that is a dense and brittle host rock. This unit hosts stockwork and breccia hosted mineralization adjacent to the veins, especially where secondary hanging wall veins such as the Carmen splays (see samples S049 and S058) and Hilos 1 and 2 vein intersections.

Description of the current work program and history of the underground mining

The underground work program initiated at the Carmen deposit was aimed at providing more than 650 metres of underground access to high-grade gold-silver mineralized structures, including the Carmen and Hilos structures (see figures 2 and 3 below). Thus far access has been achieved within all four of the targeted adits and total access exceeds 965 metres within the historic underground mine workings. Levels rehabilitated currently include Hilos Mine levels 0 and 1 (results released on December 20, 2012) and Carmen Mine levels 1 and 3. Assay results have been received for sampling on the Hilos levels 0 & 1 and Carmen 1 level. Rehabilitation and sampling continues on the Carmen Level 3 workings. 

Figures 1 & 2 show the spatial relationship of the historic workings with relation to the proposed Open Pit as outlined in the 2011 Preliminary Economic Assessment (the "PEA"). While the levels being sampled are within the proposed Open Pit, the sampling and mapping will provide important insight in respect of the continuity of the same vein structures below the proposed pit bottom. This information will be incorporated into the ongoing economic and engineering studies of the Carmen deposit development alternatives.

Figures 3 & 4 show the sample station locations within Carmen level 1. See the company website at www.kimberresources.com for a full table of the sample data. 

Historic production of gold and silver ores from the Monterde underground mine took place between 1937 and 1944. Total production has been estimated at 68,000 tonnes grading 19.29 g/t gold and 311.5 g/t silver. The mining cut-off grade is reported to have been approximately 15.0 g/t gold. All of the material produced was oxide in nature. Historic mining depths were greater than 250 metres vertical. Production was from two underground mines located on two separate shears, Carmen and Los Hilos, separated by an east-west distance of approximately 150 metres.

Sampling Program Description and QA/QC

Sampling within the underground workings included Diamond saw channel sampling, taken in compliance with the Company's core drilling QA/QC protocol, and have been analyzed for gold, silver and trace elements with ALS Chemex laboratory. The vein exposures in the back (roof) and face of the workings are sampled in stations perpendicular to the strike of the structure, with the widths of the individual samples determined by the mineralization and alteration. Sample stations include one to four continuous channel samples, with the hanging wall, vein and footwall mineralization separated into individual samples. Sample stations are spaced at approximately 2 metre intervals along the vein except in areas where historic mining has removed the vein. Minimum sample width was 0.4 metres and maximum was 2.0 metres. The cross cut drifts were sampled along waist high horizontal channel samples, with sample widths again determined by mineralization, but typically on 1.5 metre intervals. The data is being compared to the drill data in the area of the sampling for validation crosschecks and to analyze trends where stronger gold-silver mineralization occurs. Sample widths reported are true thicknesses except for horizontal crosscut samples which are approximately 80-100% of true thickness. Duplicate channel samples were taken for each 20th sample with blank and standard samples inserted in the sample stream.

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 Updated Preliminary Economic Assessment for Monterde in 2011 represented a significant step forward for Kimber and supported further evaluation and more advanced economic studies at the Monterde deposits, with the recently filed 2012 Updated Mineral Resource Estimate Technical Report for the Carmen deposit representing a component of those activities.
