Kimber Reports High Grade Gold and Silver Sample Results From Underground Sampling at Monterde

Unmined Section Yields Average of 6.2 g/t Gold Eq. over 1.8m Width for 81m Strike of Level 1 of Hilos

Kimber Resources Inc. (TSX:KBR)(NYSE MKT:KBX)(NYSE Amex:KBX) is pleased to announce the first set of results from its underground rehabilitation and sampling program within the historic Los Hilos level 0 and 1 underground workings of the Carmen deposit at the 100% owned Monterde gold-silver project in Chihuahua, Mexico. Assay results from levels 0 and 1 at Hilos show significant gold and silver mineralization remaining in the historic workings in areas of the vein structure that were not removed by mining in the 1930s and 1940s. The highest precious metal values were associated with banded epithermal quartz veining, stockworks and stronger silicification. 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.
Highlights from the sampling program are as follows:

** Horizontal Samples are estimate between 80-100% of true width.

The sampling on the upper adit (Level 1) in the unmined section beyond the last historic stope yielded a weighted average grade of 2.7 g/t gold and 181 g/t silver (6.2 g/t gold equivalent over 1.8 metres average sample width (true width) representing 81 metres of strike length along the vein (see Figure 3). Sections of the vein that were not mined out by the operators in the 1940's on the lower Hilos 0 level included 15 metres of strike averaging 2.2 g/t gold, 79.0 g/t silver (3.7 g/t gold equivalent) and 18 metres of strike averaging 6.0 g/t gold, 201.6 g/t silver (9.8 g/t gold equivalent (see Figure 2). See Appendix I for detailed sample data. The mined sections of these levels could not be sampled as they were fully stoped out, but suggest attractive grades were present in these areas too.

"Results from the underground sampling of the historic adits of the Hilos structure have provided us with an increased level of confidence in the grade and continuity of the high grade zones of gold-silver mineralization within the Carmen deposit," reported Gordon Cummings, President and CEO of Kimber Resources. "The assay results from Hilos Level 1 historic adit exceeded our expectations, with excellent gold-silver grades within a structure that shows strong visual continuity supported by geology and assay analysis. Results from Hilos Level 0 returned good gold and silver values despite historic mining efforts targeting mineralization in that area. These underground assay results will provide good additional information on the gold-silver mineralization of Hilos as we proceed towards a pre-feasibility study in 2013."
The sampling results at Hilos have successfully provided valuable information including:
  1. Support of continuity of the high grade mineralization on the Hilos vein structure between the old mine workings.
  2. Distribution of gold and silver within the mineralized zones on the Hilos structure.
  3. Mineralization controls, both structural and geological.
  4. Ground conditions for mine development planning and economics.

The underground work program initiated at the Carmen deposit was aimed at providing more than 1,000 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 and Carmen Mine levels 1 and 3. Assay results have been received for sampling on the Hilos levels 0 and 1. Sampling of the Carmen 1 level was completed in early December and the assays are pending. Rehabilitation and sampling continues on the Carmen Level 3 workings.

Figures 1-3 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 on development 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.
Historic production of gold and silver ores from the Monterde underground mine took place between 1937 and 1944. Total ore 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 ore 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.

The larger of the two mines was centred on the Carmen Shear. Production was accessed from three main surface adits connecting with four internal shafts and raises connected to multiple levels with stopes on four ore shoots. The stoped areas vary in strike length from 30 metres to over 90 metres. Down dip extent of the stopes ranges from 60 metres in the "Number 2 Orebody" to over 250 metres in the "Number 3 Orebody". The average stope width was 2 metres, although drilling has encountered stopes as wide as 6 metres true width. The smaller mine was located on the Los Hilos Shear. The Los Hilos mine was stoped along a strike length of 45 m and over a depth of approximately 100 metres. Stope widths on the Los Hilos Shear averaged approximately 1.5 metres wide.

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.
