VANCOUVER, BRITISH COLUMBIA, Jul 23, 2008 (MARKET WIRE via COMTEX News Network) --

Tres-Or Resources Ltd. (TSX VENTURE: TRS) ("Tres-Or") is pleased to provide an update on the progress of processing the Lapointe Kimberlite macro-diamond test at the Stornoway Diamond Corporation ("Stornoway") dense media separation (DMS) facility in Thunder Bay, Ontario. This facility is operated by Microlithics Laboratories Inc. ("Microlithics"), under agreement with Stornoway, and Stornoway in turn has agreed to process the Lapointe sample for Tres-Or at cost.

The Lapointe Kimberlite sample was collected in February, 2008, from a single, large diameter RC drill hole, and represents approximately 60 tonnes of in-place kimberlite. This sample arrived at the DMS facility from secure storage at DRA America (DRAA)'s independently controlled warehouse facility at the end of June, 2008, and the preliminary concentrate has been completed.

The preliminary concentrate from the DMS facility is being further reduced by caustic fusion procedures at the Microlithics lab in preparation for final diamond picking. Results will be announced upon completion.

Tres-Or holds 100% interest in the Lapointe pipe subject to a 5.0% Net Profits Interest granted to Arctic Star Diamonds Corporation. In circumstances where Tres-Or receives an offer to acquire an interest in Lapointe or Tres-Or determines to sell, assign or transfer any of its interest in Lapointe, then Stornoway shall have a 30 day period in which to accept or match the offer in order to exercise its first right under the agreement.
