VANCOUVER, BRITISH COLUMBIA — (Marketwire) — 05/29/12 — Kimber Resources Inc. (TSX:KBR)(NYSE MKT:KBX)(NYSE Amex:KBX) is pleased to announce the results from two drill holes designed to test for new structures in the “Carmen East” area on its 100%-owned Monterde property. Drill hole MTC-163 intercepted multiple mineralized structures, including two with high-grade gold-silver mineralization: one returning 4.3 g/t gold and 166.6 g/t silver over 2.1 metres and the other grading 3.2 g/t gold and 222.0 g/t silver over 1.5 metres.

“Kimber is delighted to have discovered multiple new mineralized structures to the northeast of the Carmen deposit in an area not previously drilled, including an intercept of 4.3 g/t gold and 166.6 g/t silver over 2.1 metres,” reported Gordon Cummings, President and CEO of Kimber Resources. “The area to the east and northeast of the current Carmen deposit has the potential to host multiple structures with significant gold and silver values, and Kimber sees this zone as an excellent target for further exploration drilling.”

Highlights of recent assay results are tabulated below, while complete results for the two drill holes are tabulated at the end of this news release:

(i) Structure strike and dip are unknown, so true widths are also unknown.

(ii) Gold equivalent grade assumes equivalence of 60 grams of silver to one

gram of gold.                                                               

The two holes were targeted to the northeast of the current Carmen deposit, in an area known as Carmen East: an area that has never previously been drilled. Kimber recently recognized that the Carmen East area has the potential to host additional structures containing high-grade gold-silver mineralization and the discovery of the Cocos zone (grading 18.3 g/t gold and 374.3 g/t silver over 7 metres reported on January 26, 2012), coupled with the results of MTC-163 further support this geologic theory.

Gold-silver mineralization was also intercepted in a number of other structures throughout MTC-163, including 264.4 to 272.0 metres returning 0.40 g/t gold and 32 g/t silver and 277.5 to 283.5 metres returning 0.6 g/t gold and 24 g/t silver. These multiple intercepts of elevated gold-silver mineralization support the potential for Carmen East to host a number of additional structures which may have the potential to carry high-grade gold-silver mineralization along strike or up and down dip from these lower grade intercepts, as is seen in structures within the Carmen area.

Drill hole MTC-164 was also situated to target the area northeast of Carmen. No significant gold and silver values were intercepted by MTC-164, however MTC-164 was a significant step out from Carmen and it is possible that the position may not have been appropriately located to intercept those structures identified in hole MTC-163.

Update Mineral Resource Estimate

Kimber continues to advance towards the completion of its Updated Mineral Resource Estimate for the Carmen deposit.

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 supports further development and more advanced economic studies at the Monterde deposits. The subsequent discovery of high grade gold-silver mineralization below the mineral resources used in the preliminary economic assessment adds a potentially significant new dimension to the opportunities at Monterde.

Quality Assurance/Quality Control

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements set out in National Instrument 43-101 and reviewed and approved by Mr. James A. Currie, P.Eng., Chief Operating Officer of the Company. The exploration activities at the Monterde project site are now carried out under the supervision of James A. Currie, P.Eng., who is the designated Qualified Person under National Instrument 43-101 for the Monterde project and is responsible for quality control at Monterde and has verified the data being disclosed herein. He has determined that the laboratory reports matched the drill sample logs and that the quality control assays fall within reasonable limits. QA/QC procedures incorporate blanks and duplicates inserted at the drill and standards inserted after sample preparation. Sample preparation was done by ALS Chemex at its Chihuahua laboratory. 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 in this news release and on its website, such as “measured”, “indicated”, and “inferred”, “mineral resources”, which the SEC guidelines strictly prohibit U.S. companies from including in their filings with the SEC.
