(TSX VENTURE:KWG)("KWG") announce the receipt of a report prepared by SGS SGS Société Générale de Surveillance SGS Symantec Gateway Security (appliance) SGS School of Graduate Studies SGS Subgrid Scale SGS Singapore Government Securities SGS Shell Global Solutions Lakefield Research Limited entitled "The Ore Characteristics of Samples from the Wawa Deposit", dated March 3, 2006. The preliminary caustic fusion diamond results were previously disclosed in a press release issued February 20, 2006. This report presents and discusses the potential beneficiation beneficiation Treatment of raw material (such as pulverized ore) to improve physical or chemical properties in preparation for further processing. Beneficiation techniques include washing, sizing of particulates, and concentration (which involves the separation of valuable (crushing and separating rock into valuable substances or waste by any of a variety of techniques) of the diamond bearing xenolith from the matrix that hosts the xenolith in a particular diamond occurrence located on the joint venture's 45 square kilometer property situated 35 km. north of Wawa, Ontario Wawa, Ontario is a community in Northern Ontario, Canada, located in Michipicoten Township in the Algoma District. The community is known for its 28-foot-tall metal statue of a Canada goose, which was built in 1963. . The report presents details of the various laboratory tests performed on three samples, representing the xenolith fraction, the matrix fraction and ROM (run of mine) composite fraction. These tests were designed to better understand the overall recoverability of diamond from the rock, and to determine what process(s) can be used to separate the diamond bearing xenoliths from the less diamondiferous matrix. Tests included but were not limited to; geochemistry, mineralogy mineralogy Scientific study of minerals, including their physical properties, chemical composition, internal crystal structure, occurrence and distribution in nature, and origins or conditions of formation. , specific gravity specific gravity, ratio of the weight of a given volume of a substance to the weight of an equal volume of some reference substance, or, equivalently, the ratio of the masses of equal volumes of the two substances. and bulk density, magnetic susceptibility Magnetic susceptibility The magnetization of a material per unit applied field. It describes the magnetic response of a substance to an applied magnetic field. and grindability. The SGS Lakefield Research Report erroneously refers to the sampled rock as "ore" throughout, and occasionally the word "mine" is mentioned therein. The reader is cautioned that neither Spider or KWG consider the Wawa project to be hosting "diamond ore" in the proper sense of the phrase at this time, nor is there a "mine" currently present on the property. The aforementioned words were used by the rock beneficiation department at SGS Lakefield Research only, as they typically process and study "ores" from various other deposits. The program that SGS Lakefield Research was mandated with, in this case deals with the rock characteristics and the recoverability of xenoliths and contained diamonds therein. The following text represents excerpts from the Summary and Conclusion section of the in-house report. "It was determined that both rock types (matrix and xenolith) have similar mineralogical min·er·al·o·gy n. pl. min·er·al·o·gies 1.

The xenolith rocks consist mainly of amphiboles (79%) and mica (11%) while the predominant minerals in the matrix are mica (48%), plagioclase feldspar plagioclase feldspar (plā`jēəklās'): see feldspar. (27%) with lesser amounts of amphiboles (11%)." "The two rock types have similar physical properties. The xenolith rocks are slightly heavier on average, but their distribution of density overlaps that of the matrix.

Verb 1. beneficiate - process (ores or other raw materials), as by reduction metallurgy - the science and technology of metals the xenolith, but significant inefficiencies will occur, although any free diamonds would be recovered with the xenolith rocks." "The distribution of the magnetic susceptibility for the xenolith and matrix rocks are very similar, so magnetic separation can likely not be used for xenolith beneficiation. Magnetic separation can only be used to separate liberated diamond. Any locked diamond would likely be rejected with the magnetic phase." "Both rock types depicted similar responses to grindability testing at various energy input levels, which eliminates selective grinding selective grinding, n See grinding, selective. as a potential beneficiation aid. The two rock types are very hard in comparison with other (kimberlitic) diamond ores, which will make the diamond liberation process more difficult. A multi-stage separation approach, with intermediate low energy input grinding, is recommended to maximize diamond liberation, while minimizing diamond breakage. Some diamond breakage and/or losses will be unavoidable." "Ore sorting Ore sorting refers to the process of separating an ore into separate constituent parts. Today, ore sorters are widely used in industrial mineral mines, diamond mines and base and precious metal mines. (as performed at the site) is likely to be the most successful beneficiation route. Electronic sorting, based on image analysis, can sort rocks by colour and/or shape. This may be combined with dense-media separation in the processing flowsheet." "The MgO, Cr, Ni (and others such as Al, Na, P, Sr, etc.) can be used as a guide to differentiate between the xenolith material and the matrix. This will require a relatively simple analytical technique An analytical technique is a method that is used to determine the concentration of a chemical compound or chemical element. There are a wide variety of techniques used for analysis, from simple weighing (gravimetric) to titrations (titrimetric)to very advanced techniques using to measure and could be done on site with portable XRF XRF X-Ray Fluorescence XRF X-Ray Flash XRF Cross Reference XRF Extended Recovery Facility (IBM) XRF Extended Reliability Feature XRF Cross Reference File XRF External Reference (xray fluorescence) instrumentation.

"The parallel caustic fusion work confirmed the preferential concentration Preferential Concentration is the tendency of dense particles in a turbulent fluid to cluster in regions of high strain (low vorticity) due to their inertia. The extent by which particles cluster is determined by the Stokes number, defined as  Details of that work have previously been released (February 20, 2006), but are re-presented here for ease of reference:

"A total of 244 diamonds weighing 0.051 carats were found in the xenolithic material compared to 67 and 87 for the matrix and ROM, respectively. Sixteen diamonds in the xeno sample were greater than 0.5 mm in at least one dimension compared to only one in the matrix, indicating that the xenolith preferentially host the largest diamonds. The xenolith diamonds were also whiter on average." In summary, the testwork done on the selected samples is encouraging, as there are physical properties that distinguish the host relatively diamond-poor matrix from the relatively diamond-rich xenolith portion of the rock. These differences can be utilized in the design of a flow sheet as required for the processing of the rock, that may cost effectively liberate diamonds from the rock in a production situation, if and when warranted. The beneficiation study suggests that simple electronic sorting coupled with dense media separation may be the preferred route to take in processing the Wawa diamond bearing rocks. All samples reported upon herein were selected by James G. Burns P.Eng., (Independent Qualified Person) Neil Novak P.Geo. (representative of Spider/KWG Joint Venture), and Andre McKen (representative of SGS Lakefield Research Ltd.). The 3 samples were processed by caustic dissolution at the SGS Lakefield Research laboratory located in Lakefield, Ontario Lakefield (population 2400) is a village which is a part of the township of Smith-Ennismore-Lakefield, and Peterborough County, Ontario, although it was formerly a separate village. The Trent-Severn Waterway passes on the west. . They have provided individual descriptions (xyz dimensions, crystal descriptions, actual carat weight of larger stones). The samples reported herein were individually bagged and sealed by James Burns

Only those diamonds that were captured on a 0.105 mm sieve or greater were collected and reported upon. The technical information presented herein, was compiled and prepared by Neil Novak P.Geo. in his capacity as the appointed manager of the KWG - Spider Ontario joint venture. Spider is now planning the follow-up to the SGS Lakefield Research recommendations. Plans include diamond drilling the main diamond occurrence that has been mapped and sampled over an area 300 meters by 15 meters (open to north and south). A current NI-43-101 report is being prepared and finalized by James Burns P.Eng., that summarizes all of the exploration work done on this property since its acquisition in 1996, this report will be filed with Sedar upon completion. As this project falls within the scope of what Spider has agreed to with KWG pertaining to amendments to the existing joint venture, and since the Wawa project is a focus project for Spider and not KWG, Spider will continue the exploration work on this project alone. Under the terms of the proposed new amendment to the joint venture, KWG will have the option of participating in additional exploration work on this project, once their interest is diluted down to 33.3%.
