Diamcor Mining Enters Into Agreement With Trans Hex for Exploration on Diamcor's “So Ver” Mining Area


KELOWNA, BRITISH COLUMBIA, CANADA, May 31, 2007 – Diamcor Mining Inc. (TSX-V:DMI) (“Diamcor” or the “Company”) announced today that it has signed a memorandum of understanding for a joint venture agreement with Trans Hex Group Limited (JSE:TSX) and its joint venture partners (collectively “Trans Hex”) to perform exploration on various new and yet unexplored portions of Diamcor’s So Ver land holdings in South Africa. Trans Hex has been evaluating geophysical anomalies outside the So Ver mining area and is in possession of exploration information that suggests there may be potential to discover additional kimberlite bodies on these yet unexplored parts of the Diamcor property. The new targets identified are part of an area covered by both an old order prospecting right previously granted to Diamcor and a recent new order prospecting right granted to Trans Hex. The areas in question are not associated with the previously announced Doornkloof exploration undertakings.

Under the terms of the joint venture understanding, Diamcor will allow Trans Hex access to sample all geophysical targets identified in the area and in exchange retain a 7.5% interest in any project that may follow from the exploration targets identified. Trans Hex has agreed to fund these projects through feasibility, after which all post-feasibility funding would be in proportion to each party’s interest in any subsequent project that may result. Any resulting post-feasibility project will be overseen by a joint venture management committee, but the project will be operated and managed by Trans Hex. Trans Hex will also be responsible for the marketing of any diamonds produced through Trans Hex Diamond Trading.

“We welcome the opportunity to work with Trans Hex, in further evaluating the new anomalies they have identified on our land holdings, and to the potential discovery of additional kimberlite bodies that could result in a viable project at a later date,” commented Dean Taylor, Diamcor President and Chief Operating Officer.
